20.What is the main adverse effect of aminoglycosides to monitor? a) Nephrotoxicity b) Hepatotoxicity c) Cardiotoxicity d) Both a and c Aminoglycosides can cause nephrotoxicity and ototoxicity but not cardiotoxicity; however, answer d is incorrect, so best is nephrotoxicity only. (Adjust to clarify: Best answer is a) Nephrotoxicity) 20 (Revised). What is the main adverse effect of aminoglycosides to monitor? a) Nephrotoxicity b) Hepatotoxicity c) Cardiotoxicity d) Neurotoxicity a) Nephrotoxicity Aminoglycosides are nephrotoxic and require monitoring kidney function during therapy. 21.A patient is prescribed metformin.

22.Which of the following medications is contraindicated during pregnancy? a) Penicillin b) Warfarin c) Acetaminophen d) Insulin Warfarin is teratogenic and contraindicated in pregnancy due to risk of fetal hemorrhage and malformations. 23.Which class of drugs is most effective for treating acute asthma exacerbations? a) Beta blockers b) Beta-2 agonists c) ACE inhibitors d) Calcium channel blockers Beta-2 agonists cause bronchodilation and relieve acute bronchospasm in asthma. 24.Which neurotransmitter is primarily affected by benzodiazepines? a) Dopamine b) Gamma-aminobutyric acid (GABA) c) Serotonin d) Norepinephrine Benzodiazepines enhance the effect of GABA, an inhibitory neurotransmitter, producing sedation and anxiolysis. 25.Which drug requires monitoring of trough levels to prevent toxicity? a) Amoxicillin
c) Immunosuppression d) Bradycardia Corticosteroids suppress immune function, increasing risk of infections. 29.Which of the following drugs is commonly used to treat tuberculosis? a) Ciprofloxacin b) Isoniazid c) Metronidazole d) Acyclovir Isoniazid is a first-line antitubercular agent. 30.Which electrolyte imbalance is a common side effect of thiazide diuretics? a) Hyperkalemia b) Hypokalemia c) Hypercalcemia d) Hyponatremia Thiazides cause potassium loss, leading to hypokalemia. 31.What class of drugs does atropine belong to? a) Beta blockers b) Anticholinergics c) Diuretics d) ACE inhibitors Atropine blocks acetylcholine at parasympathetic sites, increasing heart rate and reducing secretions. 32.A patient on lithium therapy should have which lab monitored regularly? a) Blood glucose
b) Serum lithium levels c) Liver enzymes d) Serum calcium Monitoring lithium levels is crucial due to its narrow therapeutic index and risk of toxicity. 33.Which medication is used to reverse opioid overdose? a) Flumazenil b) Atropine c) Naloxone d) Protamine sulfate Naloxone competitively blocks opioid receptors, reversing respiratory depression caused by opioid overdose. 34.Which medication requires the patient to avoid consuming grapefruit juice? a) Metformin b) Lisinopril c) Simvastatin d) Furosemide Grapefruit juice inhibits CYP3A4 enzyme, increasing simvastatin blood levels and risk of toxicity. 35.Which vitamin deficiency is associated with isoniazid therapy? a) Vitamin D b) Vitamin C c) Vitamin B6 (pyridoxine)
b) Haloperidol c) Lithium d) Diazepam Haloperidol is a typical antipsychotic used to treat schizophrenia and other psychoses. 40.Which class of antibiotics inhibits bacterial cell wall synthesis? a) Macrolides b) Aminoglycosides c) Beta-lactams d) Fluoroquinolones Beta-lactams like penicillins and cephalosporins inhibit bacterial cell wall synthesis causing cell lysis. 41.Which drug is used to treat anaphylaxis? a) Diphenhydramine b) Epinephrine c) Albuterol d) Epinephrine Epinephrine is the drug of choice for anaphylaxis because it reverses airway constriction and hypotension rapidly. 42.Which medication requires regular monitoring of liver function tests? a) Metformin b) Lisinopril c) Isoniazid d) Furosemide
Isoniazid can cause hepatotoxicity, so liver enzymes should be monitored regularly. 43.Which medication can cause a “disulfiram-like” reaction when taken with alcohol? a) Metronidazole b) Ciprofloxacin c) Metronidazole d) Amoxicillin Metronidazole inhibits aldehyde dehydrogenase, causing unpleasant symptoms when alcohol is consumed. 44.Which medication is used as first-line therapy for type 2 diabetes? a) Glipizide b) Insulin c) Metformin d) Sitagliptin Metformin improves insulin sensitivity and reduces hepatic glucose production. 45.Which medication is classified as a calcium channel blocker? a) Metoprolol b) Lisinopril c) Amlodipine d) Furosemide Amlodipine inhibits calcium influx into vascular smooth muscle, causing vasodilation and decreased blood pressure.
d) Allopurinol Allopurinol reduces uric acid production, preventing gout attacks. 50.Which of the following drugs is considered a controlled substance due to potential for abuse? a) Acetaminophen b) Ibuprofen c) Morphine d) Amoxicillin Morphine is an opioid analgesic with high potential for dependence and abuse. 51.Which medication is an example of a macrolide antibiotic? a) Ciprofloxacin b) Gentamicin c) Azithromycin d) Cephalexin Azithromycin is a macrolide that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit. 52.A patient taking digoxin complains of visual disturbances and nausea. What is the nurse’s best action? a) Increase the dose b) Assess for digoxin toxicity c) Ignore symptoms d) Give antacids
