Question 1

Which medication is used to treat type 2 diabetes?

Accepted Answer

Answer reason: This drug decreases gluconeogenesis in the liver and increases peripheral insulin sensitivity, lowering fasting and postprandial glucose without causing hypoglycemia when used alone. It is widely recommended as initial pharmacotherapy alongside lifestyle modification for most adults with type 2 diabetes. By contrast, a statin treats dyslipidemia, an ARB treats hypertension/proteinuria, and an antihistamine treats allergic symptoms, none of which directly lower blood glucose.

Question 2

Sedative effect sabse zyada kis drug me hota hai?

Accepted Answer

Answer reason: This drug is also significantly anticholinergic, which further contributes to drowsiness, impaired concentration, and psychomotor slowing. In contrast, second-generation antihistamines like fexofenadine, loratadine, and desloratadine are more peripherally selective and have minimal CNS penetration, so they are far less sedating. Therefore, among the listed options, the one expected to cause the most sedation is the first-generation agent.

Question 3

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal thrombocytopenia?

Accepted Answer

Answer reason: Warfarin readily crosses the placenta and is classically avoided in pregnancy because it can produce fetal anticoagulation and hemorrhagic effects. Heparin is associated with heparin-induced thrombocytopenia as an immune-mediated adverse effect and is treated as a key thrombocytopenia-related risk in anticoagulant selection questions. By contrast, NSAIDs like ibuprofen/aspirin are more associated with fetal renal effects and premature ductus arteriosus closure later in pregnancy rather than being the prototypical cause of fetal thrombocytopenia in exam framing.

Question 4

A patient with hypertension and gout is prescribed losartan. The beneficial effect on uric acid is?

Accepted Answer

Answer reason: This makes it a preferred antihypertensive choice for patients with gout compared with agents that raise uric acid (e.g., thiazide diuretics). The beneficial effect is therefore lowering uric acid rather than increasing it or having no effect. It does not characteristically precipitate gout flares as a direct pharmacologic effect.

Question 5

What is the primary use of Artemether injection?

Accepted Answer

Answer reason: The injectable formulation is used for malaria, particularly when oral therapy is not feasible or in severe/complicated cases as part of artemisinin-based treatment strategies. It is not an antibiotic, antiviral, or antifungal and therefore would not be expected to target typical bacterial, viral, or fungal pathogens. The key testable point is matching the drug class (artemisinin derivatives) with its primary indication (malaria).

Question 6

Which antibiotic causes red-man syndrome if infused too quickly?

Accepted Answer

Answer reason: Rapid IV administration of this drug can cause flushing, pruritus, erythema (especially face/neck/upper torso), and sometimes hypotension. The risk is reduced by slowing the infusion rate (typically at least 60 minutes, longer for higher doses) and, when needed, premedicating with an antihistamine. The other listed antibiotics are associated with different hallmark toxicities (e.g., beta-lactam allergy with penicillin; nephro/ototoxicity with gentamicin) rather than infusion-rate–dependent flushing.

Question 7

Statins lower LDL primarily by?

Accepted Answer

Answer reason: This triggers increased expression of LDL receptors on the liver cell surface, which boosts clearance of circulating LDL particles from the blood—this is the main mechanism responsible for LDL reduction. In contrast, binding bile acids is the primary action of bile acid sequestrants, and inhibiting intestinal cholesterol absorption is the mechanism of ezetimibe. Increased biliary excretion is not the primary pathway by which statins lower LDL in clinical practice.

Question 8

Which of the following is a commonly used antacid?

Accepted Answer

Answer reason: This option is a classic over-the-counter antacid that raises intragastric pH by acid neutralization. In contrast, famotidine and ranitidine are H2-receptor antagonists that reduce acid secretion rather than neutralize existing acid. Omeprazole is a proton pump inhibitor that suppresses acid production more slowly and is not classified as an antacid.

Question 9

Which of the following is a statin drug?

Accepted Answer

Answer reason: Among the choices, only this drug name ends with the characteristic “-statin” suffix and belongs to the statin class. Warfarin is an anticoagulant (vitamin K antagonist), and aspirin and ibuprofen are NSAIDs/antiplatelet-analgesic agents rather than cholesterol-lowering drugs. Therefore it is the only option that matches the pharmacologic class being asked.

Question 10

Which drug is used to treat epilepsy?

Accepted Answer

Answer reason: Phenytoin is a classic antiseizure medication that primarily blocks voltage-gated sodium channels, helping prevent seizure propagation (notably in focal and generalized tonic-clonic seizures). Aspirin is an analgesic/antiplatelet, propranolol is a beta-blocker used for cardiovascular conditions and tremor, and metformin is an antihyperglycemic for type 2 diabetes. Therefore, the only option that directly treats epilepsy is the antiseizure agent listed.

Question 11

All these antihypertensive drugs are safe in pregnancy, except which?

Accepted Answer

Answer reason: This leads to fetal renal dysgenesis with oligohydramnios, pulmonary hypoplasia, growth restriction, and neonatal renal failure, especially with 2nd/3rd trimester exposure. In contrast, labetalol, nifedipine, and methyldopa are standard first-line/commonly used agents for chronic hypertension or acute BP control in pregnancy due to better fetal safety profiles. Therefore the ACE inhibitor listed is the unsafe choice.

Question 12

Which drug is a direct-acting vasodilator?

Accepted Answer

Answer reason: Hydralazine fits this mechanism and is classically categorized as a direct arteriolar vasodilator used in hypertension (including in pregnancy) and in selected heart failure regimens. Aspirin is an NSAID/antiplatelet agent, phenytoin is an antiepileptic sodium-channel blocker, and metformin is an antihyperglycemic; none are primary direct vasodilators. A common testable consequence of hydralazine’s arteriolar dilation is reflex sympathetic activation, leading to tachycardia and fluid retention, often prompting combination with a beta-blocker and diuretic.

Question 13

Which drug is a direct renin inhibitor?

Accepted Answer

Answer reason: This mechanism uniquely matches one medication in the list. In contrast, losartan is an ARB (blocks angiotensin II receptors) and lisinopril is an ACE inhibitor (blocks conversion of angiotensin I to II), which are downstream targets. Amlodipine is a dihydropyridine calcium channel blocker and does not act on the RAAS pathway.

Question 14

The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) and a significant family history of coronary artery disease. Which of the following prescriptions by the health care provider would treat a major modifiable risk factor of coronary artery disease?

Accepted Answer

Answer reason: Major modifiable risk factors for coronary artery disease include dyslipidemia, hypertension, diabetes, and smoking, and lowering LDL cholesterol reduces atherosclerotic event risk. A statin directly treats hyperlipidemia by inhibiting HMG-CoA reductase, lowering LDL and stabilizing plaque, which addresses a key modifiable CAD risk factor. The other options are COPD therapies (systemic steroid, ICS/LABA, and SABA) and do not target lipid-driven atherosclerosis. In a patient with strong family history, lipid-lowering therapy is a high-yield preventive intervention when indicated by risk assessment.

Question 15

Which symptom of hypoglycemia will be present in a patient even he's taking beta blocker?

Accepted Answer

Answer reason: Diaphoresis is largely mediated by sympathetic cholinergic (muscarinic) pathways rather than beta receptors, so it tends to remain a reliable sign. Tremor is more beta-2 mediated and can also be reduced, making it less dependable than diaphoresis. Therefore, persistent sweating is the best expected symptom even when a patient is taking a beta-blocker.

Question 16

What is the primary function of the drug albuterol?

Accepted Answer

Answer reason: This directly addresses acute bronchospasm and reversible airflow obstruction seen in asthma (and COPD), improving wheeze and shortness of breath. It does not treat infection or fever because it has no antimicrobial or antipyretic mechanism. It also is not primarily an anti-inflammatory analgesic; airway inflammation is targeted by corticosteroids rather than SABAs.

Question 17

What are the potential side effects of antacids?

Accepted Answer

Answer reason: Magnesium-containing antacids commonly cause osmotic diarrhea, while aluminum-containing antacids tend to cause constipation by slowing intestinal motility. Many OTC antacid products combine magnesium and aluminum salts to blunt either extreme, highlighting these as the classic side effects tested. Other listed symptoms can occur nonspecifically, but they are less characteristic and less predictive of antacid type.

Question 18

What is the primary use of nitroglycerin?

Accepted Answer

Answer reason: Its predominant clinical benefit in acute angina is venodilation that reduces preload and myocardial oxygen demand, quickly relieving ischemic chest pain; it can also dilate coronary arteries and improve perfusion. Diabetes management and seizure control are unrelated to its mechanism and therapeutic class. Although it can lower blood pressure, that effect is secondary and not its primary indication in routine practice compared with angina relief.

Question 19

Which analgesic drug is often used to treat nerve pain?

Accepted Answer

Answer reason: Certain antidepressants (especially TCAs like amitriptyline and SNRIs like duloxetine) enhance descending inhibitory pathways via serotonin and norepinephrine, making them first-line options for many neuropathic pain syndromes. NSAIDs and acetaminophen mainly target inflammatory/prostaglandin-mediated nociceptive pain and are often inadequate for nerve pain. Opioids can provide analgesia but are not typically preferred for chronic neuropathic pain due to limited long-term benefit and higher risk of dependence and adverse effects.

Question 20

Which antibiotic class can cause severe photosensitivity reactions?

Accepted Answer

Answer reason: This class is classically associated with pronounced sunburn-like reactions, so patients should be counseled on sun avoidance and high-SPF protection. Aminoglycosides are better known for nephrotoxicity and ototoxicity rather than UV reactions. Although some fluoroquinolones and sulfonamides can also cause photosensitivity, it is most strongly and commonly tested with this class.

Question 21

Which drug is the first-line treatment for Type 2 Diabetes?

Accepted Answer

Answer reason: This medication fits that role and is widely recommended as first-line for most nonpregnant adults when not contraindicated (notably severe renal impairment). It is weight-neutral to modestly weight-reducing and has favorable cardiometabolic effects compared with many alternatives. A common distractor here is a statin, which is used for dyslipidemia and cardiovascular risk reduction but does not treat hyperglycemia.

Question 22

What is the main therapeutic use of acyclovir?

Accepted Answer

Answer reason: Clinically it is used to treat HSV-1/HSV-2 infections (e.g., genital herpes) and varicella-zoster infections (chickenpox, shingles), reducing symptom duration and viral shedding when started early. The diabetes-related options are incorrect because acyclovir has no role in insulin secretion, insulin sensitivity, or glucose regulation. It also does not affect coagulation pathways, so it is not used for prevention of blood clots.

Question 23

Which class of drugs is contraindicated in patients with a history of liver disease?

Accepted Answer

Answer reason: In a patient with pre-existing liver disease, reduced hepatic reserve increases the likelihood of clinically significant transaminitis, hepatitis, or liver failure when exposed to hepatotoxic agents. This makes the antifungal class (particularly azoles and some other systemic agents) a high-risk choice and often contraindicated or requires strict avoidance depending on severity. In contrast, NSAIDs are more classically avoided in liver disease due to bleeding/renal effects, but they are not uniformly contraindicated as a class to the same extent as hepatotoxic systemic antifungals. The key safety principle is to avoid drugs with strong hepatic metabolism and hepatotoxic potential when hepatic function is impaired.

Question 24

Furosemide belongs to which class of drugs?

Accepted Answer

Answer reason: This pharmacologic effect is characteristic of loop diuretics and explains its common use for edema (e.g., heart failure) and hypertension when significant fluid removal is needed. It also increases urinary calcium excretion, which further distinguishes it from thiazide diuretics. The other choices are antihypertensive classes with different targets (beta-adrenergic receptors, L-type calcium channels, or the renin-angiotensin system) and do not match furosemide’s renal tubular site of action.

Question 25

What is the main therapeutic use of fluticasone?

Accepted Answer

Answer reason: Its primary therapeutic role is maintenance therapy, not rapid relief during an acute attack. Diabetes and blood glucose control are not indications for this medication, and systemic corticosteroids more commonly worsen glycemic control rather than treat it. Prevention of blood clots is managed with antiplatelets or anticoagulants, not inhaled steroids.

Question 26

What is the primary function of the drug fluticasone?

Accepted Answer

Answer reason: By decreasing airway inflammation, it reduces mucosal edema and downregulates mucus production, which lowers hyperresponsiveness and helps prevent exacerbations. It is not an antibiotic, so it does not treat bacterial infections, and it is not an antipyretic used primarily to reduce fever. Unlike short-acting beta-agonists, it does not provide rapid bronchodilation for acute symptom relief, so airway dilation is not its primary function.

Question 27

What is a common side effect of rifampin?

Accepted Answer

Answer reason: A clinically important adverse effect is liver injury, so patients require counseling about hepatitis symptoms and monitoring of liver enzymes, especially with other hepatotoxic TB drugs. Gastrointestinal upset can occur but is less distinctive and does not capture the key high-yield toxicity. Weight gain/sedation are not typical for this medication, and significant hypotension/tachycardia would suggest an acute reaction rather than the common expected effect.

Question 28

What is a key adverse effect of carbamazepine?

Accepted Answer

Answer reason: g., dizziness, ataxia) and serious hematologic toxicity from bone marrow suppression. Clinically important complications include leukopenia, agranulocytosis, aplastic anemia, and thrombocytopenia, which is why CBC monitoring and infection/bleeding vigilance are emphasized. It is also associated with significant cutaneous reactions, ranging from mild rash to severe SJS/TEN (higher risk with certain HLA variants). The other options list effects more consistent with sympathomimetic toxicity, hypoglycemic drugs, or anticholinergic agents rather than this anticonvulsant/mood stabilizer.

Question 29

Drug used for allergic rhinitis?

Accepted Answer

Answer reason: H1-receptor antagonists reduce these symptoms by blocking histamine’s effects on nasal and conjunctival tissues. Antibiotics target bacterial infections and do not treat an allergic mechanism. Antacids and analgesics may address GI acidity or pain, but they do not address the histamine-mediated pathophysiology of allergic rhinitis.

Question 30

What is the mechanism of action of opioids?

Accepted Answer

Answer reason: Receptor activation inhibits adenylyl cyclase, closes presynaptic voltage-gated calcium channels, and opens postsynaptic potassium channels, decreasing substance P and glutamate transmission in pain pathways. This produces analgesia along with predictable class effects such as sedation and respiratory depression. Calcium-channel blockade alone is not the defining pharmacologic mechanism (it is downstream of receptor activation), while carbonic anhydrase inhibition and beta-adrenergic blockade describe other drug classes.

Question 31

A patient with tuberculosis is on isoniazid. He should receive supplemental?

Accepted Answer

Answer reason: Supplementing vitamin B6 reduces the risk of paresthesias, numbness, and other neurotoxicity, especially in patients with risk factors such as malnutrition, pregnancy, HIV, diabetes, alcoholism, or renal failure. This supplementation supports normal neurotransmitter synthesis and nerve function while allowing continued effective TB therapy. Other vitamins listed are not routinely used specifically to prevent isoniazid-associated neuropathy.

Question 32

What is the drug of choice for the prophylaxis of malaria in travelers to areas with chloroquine-resistant Plasmodium falciparum?

Accepted Answer

Answer reason: falciparum, chemoprophylaxis requires an agent active against resistant strains in endemic regions. This option is a standard first-line regimen for travelers because it is highly effective and typically well tolerated, with a short post-travel continuation period compared with some alternatives. Chloroquine is ineffective in chloroquine-resistant areas, making it an unsafe choice for prevention. While doxycycline and mefloquine are also acceptable alternatives, selection commonly favors this option due to its favorable balance of efficacy, resistance coverage, and practicality for many travelers.

Question 33

What is the primary function of the drug theophylline?

Accepted Answer

Answer reason: This directly addresses bronchospasm in conditions like asthma and COPD, so improving breathing through airway smooth-muscle relaxation is the primary therapeutic effect. Reducing airway inflammation and mucus is more characteristic of inhaled corticosteroids and some leukotriene modifiers rather than theophylline’s main action. It has no antibacterial or antipyretic mechanism, making those options clearly incorrect.

Question 34

What is the mechanism of action of naloxone?

Accepted Answer

Answer reason: This rapidly counteracts opioid-induced respiratory depression, sedation, and hypotension. Because it has a shorter duration than many opioids, recurrence of toxicity can occur and monitoring for re-sedation is important. The serotonin reuptake and GABA-related options describe mechanisms of other drug classes and do not reverse opioid effects.

Question 35

Which drug is used to treat alcohol dependence?

Accepted Answer

Answer reason: Naltrexone (opioid receptor antagonist) decreases rewarding effects and craving, acamprosate modulates glutamatergic/GABA balance to support abstinence, and disulfiram inhibits aldehyde dehydrogenase to produce unpleasant symptoms if alcohol is consumed. Because each listed medication is used for alcohol dependence in appropriate patients, the inclusive choice is most accurate. A common pitfall is thinking only aversive therapy is “treatment,” but relapse-prevention agents are standard first-line options as well.

Question 36

Which drug is a cephalosporin antibiotic?

Accepted Answer

Answer reason: This medication is a third-generation cephalosporin with strong gram-negative coverage and common clinical use in infections such as pneumonia, meningitis, and gonorrhea. By contrast, erythromycin and azithromycin are macrolides (protein synthesis inhibitors), and metronidazole is primarily used for anaerobes and certain protozoa via DNA strand breakage mechanisms. Identifying the drug class by name pattern is a high-yield pharmacology skill that guides expected coverage, allergy cross-reactivity considerations, and adverse-effect monitoring.

Question 37

Which drug is an oral hypoglycemic agent?

Accepted Answer

Answer reason: This drug is a sulfonylurea that stimulates pancreatic beta cells to release insulin, thereby reducing serum glucose levels. The other options are not glucose-lowering antidiabetic drugs: ibuprofen and aspirin are NSAIDs/analgesics, and simvastatin is a lipid-lowering statin. A key safety consideration is hypoglycemia risk, especially with missed meals or in older adults.

Question 38

Which the following is an example of Anti-hypetenive drug?

Accepted Answer

Answer reason: This medication is a nonselective beta-blocker with additional alpha-1 blocking activity, which decreases heart rate/contractility and causes peripheral vasodilation, lowering blood pressure. Tolmetin is an NSAID for pain/inflammation and can worsen blood pressure control via sodium/water retention. Vinorelbine is a vinca alkaloid chemotherapy agent, not used for hypertension, and “Erymchhyin” appears to refer to an antibiotic (erythromycin), which is also not an antihypertensive.

Question 39

A patient in on lithium. Which of the following is most likely to cause lithium toxicity when taken with lithium?

Accepted Answer

Answer reason: Lithium is handled by the kidneys similarly to sodium, so anything that lowers sodium or increases proximal sodium reabsorption reduces lithium clearance and raises serum levels. Diuretics—especially thiazides—promote sodium loss and thereby increase lithium reabsorption, making toxicity more likely. This interaction can occur even at usual lithium doses, particularly with dehydration or low-salt intake. By contrast, insulin and statins do not predictably raise lithium concentrations, and beta blockers are more associated with additive bradycardia/tremor effects rather than a classic increase in lithium level.

Question 40

During an admission interview, a client reports to the nurse using several herbal and vitamin supplements daily, including echinacea. The nurse recognizes that echinacea is a popular herb used by clients primarily to?

Accepted Answer

Answer reason: Echinacea is commonly taken with the intent of preventing or shortening the duration of upper respiratory infections by promoting immune activity. This “immune boosting” use is the best-known and most frequently tested indication for the herb in nursing/pharmacology review. Options about libido, weight loss, or cognition are more characteristic of other supplements (e.g., ginseng for vitality, various stimulants for weight loss, ginkgo for cognition) rather than echinacea. Clinically, recognizing this purpose helps nurses screen for potential issues such as use in autoimmune conditions or with immunosuppressive therapies.

Question 41

What is the primary indication for levofloxacin?

Accepted Answer

Answer reason: The option describing bacterial infections directly matches its pharmacologic class and therapeutic purpose. Osteoporosis management is treated with agents like bisphosphonates or denosumab, not antibiotics. Seizure control requires antiepileptic drugs, and asthma is managed with bronchodilators and anti-inflammatory therapies rather than antibacterial agents unless a bacterial infection is present.

Question 42

Which class of drugs is used to treat respiratory diseases by inhibiting the action of phosphodiesterase-4?

Accepted Answer

Answer reason: PDE-4 inhibition increases intracellular cAMP in inflammatory cells, reducing release of pro-inflammatory mediators and helping control airway inflammation, particularly in COPD (e.g., roflumilast). The other listed respiratory drug classes act through different mechanisms: beta-agonists stimulate β2 receptors, anticholinergics block muscarinic receptors, and corticosteroids broadly alter gene transcription rather than directly inhibiting PDE-4. Therefore, the only option that directly fits the stated mechanism is the PDE-4 inhibitor class.
