Question 1

Resorption of bone tissue is done by?

Accepted Answer

Answer reason: Multinucleated osteoclasts mediate resorption by attaching to bone, creating a sealed resorption lacuna, and secreting hydrogen ions and proteolytic enzymes to dissolve mineral and organic matrix. In contrast, osteoblasts are responsible for bone formation by laying down osteoid and promoting mineralization. Osteocytes mainly maintain existing bone and coordinate remodeling signaling rather than performing primary resorptive work.

Question 2

Bones are connected by?

Accepted Answer

Answer reason: At synovial joints (as illustrated), ligaments reinforce the joint capsule and help maintain alignment during movement and weight bearing. Tendons are a common distractor because they also attach to bone, but they connect muscle to bone to transmit force for movement rather than linking bones to each other. Cartilage primarily provides a smooth, low-friction surface and shock absorption at joint surfaces, but it does not serve as the primary connective structure between bones.

Question 3

Bone destroying cells are called?

Accepted Answer

Answer reason: The cells responsible for resorption dissolve mineralized bone using acid and proteolytic enzymes, which is the defining function of osteoclasts. Osteoblasts are the bone-forming cells that lay down osteoid, making them a common distractor in “bone cells” questions. Osteocytes are mature bone cells embedded in the matrix that primarily sense mechanical stress and help regulate remodeling rather than directly resorbing bone.

Question 4

The nurse is caring for a 40-year-old male with a diagnosis of carpal tunnel syndrome of the right arm. The nurse is aware that carpal tunnel compresses which of the following locations?

Accepted Answer

Answer reason: Compression of this nerve produces paresthesia, pain, and sensory changes in the thumb, index, middle, and radial half of the ring finger, often with thenar weakness. The ulnar nerve is typically affected in Guyon’s canal (ulnar tunnel) rather than the carpal tunnel. The radial nerve and radial artery are not the primary structures traversing the carpal tunnel and therefore are not the characteristic site of compression in this condition.

Question 5

Synovial fluid helps in..?

Accepted Answer

Answer reason: Its hyaluronic acid and lubricin content create a viscous film that prevents wear during repetitive motion. It also contributes to nutrient and waste exchange for avascular articular cartilage, but that function is secondary to friction reduction. “Protection” is less specific and not the primary tested function compared with lubrication, while digestion and respiration are unrelated.

Question 6

Most common bone to get fracture in a newborn?

Accepted Answer

Answer reason: g., shoulder dystocia, large infant). The clavicle is relatively thin and acts as a strut between the sternum and shoulder, making it vulnerable when the anterior shoulder is impacted at the pubic symphysis. Typical findings include decreased arm movement on the affected side, crepitus, or a palpable bony irregularity, often with rapid healing and callus formation. Long-bone fractures like femur or radius are less common in routine vaginal deliveries and usually suggest higher-force mechanisms or obstetric instrumentation.

Question 7

How many bones are there in human vertebra?

Accepted Answer

Answer reason: The vertebral column is classically counted as 33 vertebrae in total: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal. Although the sacral and coccygeal vertebrae fuse in adulthood to form the sacrum and coccyx, they are still included in the developmental/anatomic count. This makes 33 the standard exam answer when asked for the number of vertebrae. Other totals (e.g., 25) can reflect fused adult segments counted as separate bones differently, but the question asks for vertebrae number, not fused adult spinal bones.

Question 8

Which position of the femur is accurate in relation to the acetabulum in a child with developmental dysplasia of the hip (DDH)?

Accepted Answer

Answer reason: The typical displacement is superolateral, driven by muscle forces and the deficient bony coverage, so the femur sits higher relative to the acetabulum. This anatomy explains common findings such as apparent limb shortening and asymmetric thigh/gluteal folds. Options describing inferior positioning conflict with the characteristic superior migration seen with hip dysplasia/dislocation.

Question 9

The nurse is aware that the strengthening of which muscle group is important for a client diagnosed with talipes equinovarus?

Accepted Answer

Answer reason: Rehabilitation and post-casting/bracing care aims to counter the varus/adduction component by improving eversion and abduction control at the foot and ankle. Strengthening the muscles that evert the foot (primarily the peroneal muscle group) helps oppose the tendency toward inversion/varus and supports more neutral alignment during gait. Strengthening invertors or plantar flexors would reinforce the deforming forces rather than correct them, and the plantar fascia is not a primary target for active strengthening in this condition.

Question 10

When a child is suspected of having muscular dystrophy, a nurse should expect which muscles to be affected first?

Accepted Answer

Answer reason: Early findings reflect pelvic girdle and proximal lower-extremity weakness (difficulty running, climbing stairs, frequent falls, and a positive Gowers sign). This pattern occurs because large proximal muscle groups are affected early in the degenerative process. Respiratory muscle weakness typically develops later as the disease progresses, making it a less likely first manifestation.

Question 11

A 2-year-old toddler has muscular dystrophy. His legs are held together with the knees touching. Which muscles are contracted?

Accepted Answer

Answer reason: A sustained “held together” posture reflects increased tone/contracture of the adductor muscle group (e.g., adductor longus/brevis/magnus, gracilis). In contrast, hip abductors would pull the legs apart, increasing the distance between the knees. Hip flexors and extensors primarily change the hip angle in the sagittal plane rather than drawing the knees together.

Question 12

A 70-year-old female client complains of lower back pain and is diagnosed with osteoporosis. The nurse is aware that this client is most at risk for which condition?

Accepted Answer

Answer reason: In older adults, this commonly results in vertebral compression fractures (often presenting as lower back pain) as well as hip and wrist fractures. While pain can occur, it is a symptom rather than the primary high-risk condition associated with osteoporosis. The other options describe increased bone density or sclerosis, which are not consistent with osteoporosis and therefore do not represent the key clinical risk.

Question 13

A 75-year-old client with Paget’s disease is undergoing diagnostic exams for a suspected fracture. The nurse should expect to observe which of the following types of fracture?

Accepted Answer

Answer reason: When abnormal bone fails under bending stress, a break that runs perpendicular to the long axis of the bone is commonly expected. This pattern reflects reduced ability of the diseased bone to withstand mechanical loading rather than the twisting mechanism that more often creates an oblique fracture. The other listed patterns are less characteristic as the “expected” fracture type in this metabolic bone disorder.

Question 14

The nurse is reviewing the laboratory tests of a child diagnosed with muscular dystrophy. Which laboratory test would aid in the diagnosis of this condition?

Accepted Answer

Answer reason: Among the listed choices, creatinine is most directly connected to skeletal muscle mass and can support the overall assessment of neuromuscular disease when interpreted with the clinical picture and other muscle-related labs. Bilirubin primarily reflects hepatic/biliary function, and sodium/potassium are electrolytes that are not diagnostic for muscular dystrophy. Although creatine kinase is the classic screening lab for dystrophies, it is not offered here, making creatinine the best available option.

Question 15

The nurse is assessing a child suspected of having muscular dystrophy for muscle weakness. At what age would evidence of muscle weakness associated with muscular dystrophy appear?

Accepted Answer

Answer reason: Around age 2, parents and clinicians often start noticing delayed walking/running, frequent falls, difficulty climbing stairs, and early signs such as a waddling gait. This timing aligns with progressive weakness of the pelvic girdle muscles that becomes more obvious as activity demands increase. Earlier ages may have subtle findings, but classic functional weakness is most commonly recognized around the second year of life.

Question 16

The nurse is caring for a client with severe scoliosis. The nurse determines that the client is at risk for which of the following?

Accepted Answer

Answer reason: Restriction reduces lung volumes, especially total lung capacity and vital capacity, leading to increased work of breathing and risk of hypoventilation. Options describing increases in capacity or oxygen uptake contradict the expected physiologic limitation from reduced thoracic compliance. Residual volume is typically normal or may be relatively increased in restriction rather than decreased, making that distractor incorrect.

Question 17

How would the nurse best describe Gowers’ sign to the parents of a child with muscular dystrophy?

Accepted Answer

Answer reason: This is essentially a compensatory method of getting from the floor to standing by leveraging the upper extremities when lower-extremity strength is insufficient. That description aligns best with a functional movement/transfer strategy rather than a gait pattern. A waddling gait can occur in muscular dystrophy, but it is a different finding than the classic maneuver of pushing on the thighs to stand. Muscle twitching with quick stretch describes clonus/spasticity (upper motor neuron findings), not muscular dystrophy.

Question 18

The nurse would expect her client’s suspected developmental dysplasia of the hip (DDH) to be confirmed by which diagnostic technique?

Accepted Answer

Answer reason: Plain radiography can demonstrate acetabular dysplasia and femoral head displacement, making it an accepted confirmatory diagnostic technique (especially as ossification progresses). Ortolani/Barlow findings and an audible click are screening exam clues and can be falsely positive from benign ligamentous laxity or soft-tissue snapping. Trendelenburg gait is a later functional sign and does not confirm the diagnosis by itself.

Question 19

The nurse receives a report on a child admitted with the most severe form of muscular dystrophy. The nurse knows this means the child has which type of muscular dystrophy?

Accepted Answer

Answer reason: It typically presents in early childhood with Gowers sign, calf pseudohypertrophy, and later cardiomyopathy and respiratory failure. The other listed dystrophies (facioscapulohumeral, limb-girdle, myotonic) generally have later onset and/or slower progression compared with Duchenne in children. Therefore, a report stating the “most severe form” in a child most strongly indicates Duchenne muscular dystrophy.

Question 20

Which of the following are causes of primary osteoarthritis?

Accepted Answer

Answer reason: Advancing age increases cartilage vulnerability and reduces regenerative capacity, while chronic joint overuse accelerates cartilage breakdown and osteophyte formation. Obesity contributes both by increasing load on weight-bearing joints and via inflammatory adipokines that can worsen cartilage degeneration. Diabetes mellitus is more associated with secondary/metabolic contributors and is not a classic primary cause in standard OA risk-factor framing, making options including it less correct.

Question 21

The nurse is planning to teach the parents of a child with newly diagnosed muscular dystrophy about the disease. Which description accurately describes this condition?

Accepted Answer

Answer reason: The core pathology is degeneration and replacement of muscle fibers with fat and connective tissue, which explains gradual loss of strength and function. Demyelination and upper motor neuron lesions describe primary neurologic disorders (e.g., multiple sclerosis or stroke/spinal cord UMN injury) rather than a primary muscle disease. Cortical lesions would produce central neurologic deficits (often spasticity, seizures, or focal findings) instead of the primary myopathic pattern seen in muscular dystrophy.

Question 22

The nurse is performing an admission assessment on a client with osteoarthritis. Which of the following clinical manifestations would the nurse expect to find?

Accepted Answer

Answer reason: This pattern reflects “use-related” joint pain and limited inflammation compared with autoimmune arthritis. Symmetric hand joint swelling and prolonged morning stiffness (>30 minutes) are more typical of rheumatoid arthritis due to inflammatory synovitis. Fever is not an expected manifestation of uncomplicated osteoarthritis and suggests systemic inflammation or infection instead.

Question 23

A client asks the nurse for information about osteoarthritis. What is the most appropriate information for the nurse to include?

Accepted Answer

Answer reason: Osteoarthritis is a degenerative joint disease characterized by progressive cartilage breakdown and related bony changes, making it highly prevalent in the general population. Patient teaching should emphasize accurate epidemiology, and this condition is the leading cause of arthritis-related pain and disability. The statement that it is rare is incorrect, and it can be significantly function-limiting, so describing it as rarely debilitating is misleading. Although incidence increases with age and is common in older adults, limiting it to those over 60 is inaccurate because it can occur earlier, especially with risk factors such as obesity or prior joint injury.

Question 24

The nurse observes a client who has a positive Trendelenburg gait. Which characteristic would indicate this gait?

Accepted Answer

Answer reason: When the patient bears weight on the affected side, the pelvis drops on the contralateral (swing) side rather than staying level. This produces the characteristic “hip drop” and often a compensatory trunk lean to reduce the abductor demand. Options about pelvic tilting upward or leg-length discrepancy describe other gait/alignment problems but do not define the classic Trendelenburg pattern.

Question 25

The nurse is performing an assessment on a client with a diagnosis of osteoarthritis. Which of the following clinical manifestations would the nurse expect to find?

Accepted Answer

Answer reason: It commonly affects weight-bearing and frequently used joints in a non-uniform pattern, so findings are often asymmetric and limited to specific joints (e.g., one knee worse than the other). In contrast, elevated ESR and systemic symptoms like fever/malaise point more toward inflammatory arthritides. Subcutaneous nodules are classically associated with rheumatoid arthritis rather than osteoarthritis.

Question 26

The nurse is teaching the client about the primary cause of osteoporosis. What is the most important information for the nurse to provide?

Accepted Answer

Answer reason: Osteoporosis most commonly results from an imbalance between bone resorption and bone formation, with increased osteoclast activity relative to osteoblast activity. Loss of estrogen after menopause is a major driver because estrogen normally suppresses bone resorption; when it declines, bone breakdown accelerates and bone mineral density falls. Alcoholism and malnutrition are important risk factors that can worsen bone loss, but they are not the primary underlying mechanism across the population. Osteogenesis imperfecta is a genetic collagen disorder causing brittle bones, which is distinct from osteoporosis and is not its primary cause.

Question 27

The nurse is teaching a community class about back injuries. Which of the following statements by the nurse would be the most accurate concerning the area that is common for vertebral herniation?

Accepted Answer

Answer reason: Lumbar intervertebral disc herniation most commonly occurs at the lowest, most mobile segments where mechanical load and shear forces are greatest. The L4–L5 and L5–S1 levels bear the highest stress during lifting, flexion, and rotation, making them the most frequent sites of disc protrusion. This aligns with the typical pattern of low back pain with radicular symptoms from compression of the corresponding nerve roots. Options involving upper lumbar levels (e.g., L1–L2) or lower sacral segments (e.g., S2–S3) are less commonly implicated in routine disc herniation patterns.

Question 28

The nurse is teaching a client diagnosed with degenerative joint disease about the condition. The nurse recognizes teaching has been effective when the client makes which statement?

Accepted Answer

Answer reason: Degenerative joint disease (osteoarthritis) is primarily a wear-and-tear process characterized by progressive cartilage degeneration and osteophyte formation rather than a primary systemic inflammatory synovitis. This makes “noninflammatory” the best overall description for patient teaching, even though mild secondary inflammation can occur with flares. Immune-mediated joint disease more accurately describes rheumatoid arthritis, which is autoimmune and typically presents with prominent inflammatory findings. The viral and systemic infection options describe reactive arthritis and septic/infectious arthritis patterns, not degenerative disease.

Question 29

The parents of a child with newly diagnosed developmental dysplasia of the hip (DDH) ask the nurse how their child developed this condition. The nurse explains that the greatest number of cases is caused by which condition?

Accepted Answer

Answer reason: This structural undercoverage creates hip instability that can range from mild looseness to progressive displacement over time. True dislocation represents a more severe end of the DDH spectrum but is less common as the initiating/primary condition than acetabular underdevelopment. Subluxation is typically a consequence of instability from the dysplastic socket rather than the predominant underlying cause, and fracture is not characteristic of DDH pathogenesis.

Question 30

Which finding would the nurse expect in a client with developmental dysplasia of the hip (DDH)?

Accepted Answer

Answer reason: DDH is characterized by abnormal development/instability of the hip joint that can progress to subluxation or dislocation, where the femoral head no longer sits properly within the acetabulum. The classic displacement pattern is posterosuperior migration of the femoral head relative to the acetabulum, reflecting loss of containment by the shallow acetabulum and lax supporting structures. Inferior displacement is not the typical direction described for DDH, making that distractor less consistent with standard anatomy/pathophysiology. A true capsular rupture is more consistent with acute traumatic dislocation rather than developmental dysplasia, which is a chronic developmental instability problem.

Question 31

The health care provider informs the client diagnosed with gout that his Xrays are normal. Which of the following statements by the health care provider would be most appropriate when the client asks if he still has gout?

Accepted Answer

Answer reason: " Gout is a crystal-induced inflammatory arthritis in which early disease often has no radiographic abnormalities because bony erosions and tophi take time to develop. A normal plain X-ray therefore does not exclude gout, especially in initial or intermittent presentations, and diagnosis relies more on clinical pattern and, when available, synovial fluid identification of monosodium urate crystals. Telling the client he is “cured” is inaccurate because normal imaging does not indicate resolution of hyperuricemia or future flare risk. The claim that X-ray changes are only seen with acute attacks is incorrect; chronic gout more typically produces characteristic erosive changes over time.

Question 32

A nurse is teaching the parents of a 3-month-old infant with severe torticollis who has presented with the head rotated to the left and the side bent to the right. The nurse determines that teaching has been effective when the parents identify which muscle as being shortened?

Accepted Answer

Answer reason: A head posture of rotation to the left with right side-bending matches contraction/shortening of the right sternocleidomastoid (it laterally flexes the neck to the right and rotates the face to the left). Congenital muscular torticollis most commonly involves unilateral sternocleidomastoid tightness rather than the trapezius. Therefore the identified shortened muscle must be on the right side.

Question 33

The client asks the nurse for information about osteoarthritis. What is the most appropriate information for the nurse to include about the disease?

Accepted Answer

Answer reason: Osteoarthritis is primarily a degenerative “wear-and-tear” disorder characterized by progressive breakdown of articular cartilage and changes in subchondral bone, rather than a systemic autoimmune inflammatory process. This leads to joint space narrowing, osteophyte formation, pain that worsens with activity, and stiffness that is typically brief after rest. Describing it as noninflammatory best distinguishes it from rheumatoid arthritis, which is systemic and inflammatory. While mild secondary inflammation can occur in osteoarthritis, the core pathology is cartilage degeneration in synovial joints.

Question 34

A client is diagnosed with a herniated nucleus pulposus (herniated disk). Which of the following statements should the nurse include in teaching the client about a herniated disk?

Accepted Answer

Answer reason: A herniated disc involves displacement of nucleus pulposus material through or against the annulus fibrosus, which can compress adjacent spinal nerve roots and cause radicular pain/neurologic symptoms. This option correctly links the internal disc mechanics (nuclear material stressing the annulus) to the clinically important consequence of nerve root compression. “Slips out of alignment” is more consistent with vertebral malalignment/spondylolisthesis rather than disc herniation. “Shatters” is inaccurate for typical degenerative disc herniation, and the description of the nucleus remaining centralized contradicts the defining pathology.

Question 35

Which finding should a nurse expect when assessing a neonate with a positive Galeazzi sign?

Accepted Answer

Answer reason: A positive finding is unequal knee height, indicating limb length discrepancy from posterior/superior displacement of the femoral head. This is performed with the infant supine and both knees flexed to about 90 degrees, making the asymmetry directly observable. An audible click with external rotation is more consistent with Ortolani/Barlow maneuvers rather than the Galeazzi sign.

Question 36

An 80-year-old client with pneumonia is admitted to the hospital. The client has a past medical history that includes chronic rheumatoid arthritis. Which assessment finding should the nurse expect during the physical examination?

Accepted Answer

Answer reason: Hyperextension at the proximal interphalangeal joint with flexion at the distal interphalangeal joint is a classic deformity pattern expected in longstanding disease. The other options point more toward different conditions: thickened palmar plaques are typical of Dupuytren contracture, and thenar eminence flattening suggests median nerve compression (carpal tunnel syndrome). A cystic swelling on the dorsal wrist can occur as a ganglion cyst and is not a hallmark deformity pattern used to identify chronic rheumatoid changes.

Question 37

When reviewing the chart of a 25-year-old male, the nurse reads that the client was diagnosed with an osteosarcoma of the distal femur. Which statement indicates the nurse’s correct interpretation of the client’s diagnosis?

Accepted Answer

Answer reason: Osteosarcoma is a primary malignant bone cancer that typically arises in the metaphysis of long bones, commonly around the knee (distal femur/proximal tibia), especially in adolescents and young adults. A diagnosis of osteosarcoma therefore refers to a bone-origin malignancy rather than spread to bone from another primary site. Management is usually multimodal (neoadjuvant/adjuvant chemotherapy plus limb-sparing resection when feasible), so amputation is not the only treatment. It is not a benign tumor, making characterization as nonmalignant with simple excision and grafting incorrect.

Question 38

Osteoporosis is disease of?

Accepted Answer

Answer reason: The pathology primarily affects bone remodeling, with resorption exceeding formation, leading to porous, weak bones. This directly makes it a disease of the bones rather than soft tissues or the nervous system. A common clinical consequence is low-trauma fractures (e.g., vertebral compression, hip, wrist), which reflects compromised bone strength rather than primary muscle, skin, or brain disease.

Question 39

Von Rosen's Splints used for?

Accepted Answer

Answer reason: The Von Rosen splint is an infant hip abduction orthosis used for this purpose in early-detected hip instability/dislocation. It maintains the hips flexed and abducted, supporting stable reduction and reducing risk of persistent dysplasia. Conditions like Perthes disease (avascular necrosis) and SCFE (adolescent physeal slip) require very different management (activity restriction/surgery), not abduction splinting.

Question 40

Ligaments connect?

Accepted Answer

Answer reason: This bone-to-bone attachment limits excessive movement and helps maintain proper alignment during motion and weight bearing. A common distractor is “Bone to muscle,” but that describes tendons, which transmit force from muscle contraction to bone. “Muscle to muscle” and “Muscle to skin” are not the primary anatomic role of ligaments in the musculoskeletal system.

Question 41

Hutchinson Fracture is?

Accepted Answer

Answer reason: The defining feature is involvement of the distal radius at the styloid, which distinguishes it from carpal or metacarpal fractures of the hand. Malleolar fractures involve the ankle (tibia/fibula) and therefore do not match the anatomic location implied by this eponym. Recognizing the name-to-location pairing is the key tested concept here, and the distal radius option is the only one that fits.

Question 42

A pregnant patient presents with an exaggerated curvature of the lumbar spine. What term is used to describe this finding?

Accepted Answer

Answer reason: Kyphosis refers to an excessive posterior curvature, typically of the thoracic spine (“hunchback”). Scoliosis and “lateral deviation” describe abnormal lateral curvature in the coronal plane rather than an increased lumbar inward curve. The stem specifically localizes the change to the lumbar region and implies increased anterior curvature, making this the best match.

Question 43

The nurse is aware that which type of exaggerated spinal curvature is often present in older adults?

Accepted Answer

Answer reason: This produces the classic “kyphotic” or stooped posture frequently seen in older adults. Lordosis refers to an inward curvature (typically cervical/lumbar) and is not the typical age-related exaggerated deformity. “Sacral kyphosis” is not the usual clinically emphasized exaggerated curvature pattern in geriatrics compared with thoracic involvement.

Question 44

Which cells are responsible for bone formation?

Accepted Answer

Answer reason: The correct option fits because these cells line bone surfaces during growth and remodeling and are responsible for new bone deposition. In contrast, osteoclasts perform bone resorption, increasing breakdown rather than building. Chondrocytes primarily produce cartilage matrix, and fibroblasts produce connective tissue collagen (e.g., tendons/ligaments), not mineralized bone.

Question 45

The nurse is reviewing the lab results of a patient with osteoporosis. The nurse would most likely note abnormalities in?

Accepted Answer

Answer reason: Bone mineral is primarily hydroxyapatite, so disorders of bone density most directly relate to calcium and phosphate balance. Osteoporosis reflects reduced bone mass and microarchitectural deterioration, and evaluation commonly focuses on mineral homeostasis and factors that regulate calcium–phosphate metabolism (e.g., vitamin D and PTH), where abnormalities may be detected depending on the underlying cause. Potassium is not a structural bone mineral and is not a typical lab focus for osteoporosis. Magnesium can influence PTH and vitamin D activity, but it is a less primary pairing than calcium with phosphate for expected mineral-related abnormalities.

Question 46

The nurse is caring for a patient with osteoporosis. The patient is most likely to be a(n)?

Accepted Answer

Answer reason: Osteoporosis risk rises when bone resorption chronically exceeds bone formation, which is strongly driven by aging and estrogen deficiency. After menopause, lower estrogen increases osteoclast activity and accelerates loss of trabecular bone, making fractures (hip, vertebrae, wrist) more likely. Older women also tend to have lower peak bone mass and greater lifetime bone loss than men, amplifying risk. While diabetes and other conditions can contribute to fracture risk, they are less predictive than the combined effect of postmenopausal status plus advanced age. Menstruating women are relatively protected by estrogen, and high parity alone is not the classic primary risk factor tested for osteoporosis.

Question 47

The nurse is reviewing the x-ray of a patient with a fractured tibia. The x-ray shows a fracture diagonal to the bone's long axis. What type of fracture is this?

Accepted Answer

Answer reason: A diagonal fracture line is characteristic of an oblique pattern, typically produced by an angled force. In contrast, a transverse fracture runs perpendicular to the long axis, and a linear fracture runs parallel to it. A comminuted fracture refers to the bone being broken into multiple fragments rather than the specific direction of the break.

Question 48

A nurse reviews the health care provider's dictation notes on an x-ray that conclude with the diagnosis of a fracture through the shaft with multiple bone fragments. Based on the notes, the nurse recognizes this as what type of fracture?

Accepted Answer

Answer reason: The description “through the shaft” localizes the injury to the diaphysis, but the key classifier is the presence of several fragments. Linear fractures refer to a single fracture line parallel to the long axis, oblique fractures are angled, and transverse fractures run perpendicular to the long axis; none of those terms inherently imply multiple fragments. Therefore the provider’s dictation most directly matches a comminuted pattern, commonly associated with higher-energy trauma and greater soft-tissue injury risk.
