Answers|Grade A+ Questions.
### Overview of Relias RN Pharmacology Test A
1. **What medication is a leukotriene receptor antagonist used to manage asthma?**
A. Albuterol
B. Montelukast
C. Ipratropium
D. Budesonide
**Answer**: B. Montelukast
**Rationale**: Montelukast is a leukotriene receptor antagonist that reduces inflammation in
asthma. Albuterol is a bronchodilator, ipratropium is an anticholinergic, and budesonide is a
corticosteroid.[](https://www.docsity.com/en/docs/relias-rn-pharmacology-test-a-relias-actual-

2. **Which medication is a potassium-sparing diuretic?**
A. Furosemide
B. Hydrochlorothiazide
C. Spironolactone
D. Mannitol
, **Answer**: C. Spironolactone
**Rationale**: Spironolactone (Aldactone) is a potassium-sparing diuretic that promotes
diuresis without significant potassium loss. Furosemide and hydrochlorothiazide cause
potassium loss, and mannitol is an osmotic diuretic.[](https://www.docsity.com/en/docs/relias-

3. **A nurse is administering a beta-blocker. Which medication belongs to this class?**
A. Lisinopril
B. Metoprolol
C. Amlodipine
D. Losartan
**Answer**: B. Metoprolol
**Rationale**: Metoprolol is a beta-blocker that reduces heart rate and blood pressure.
Lisinopril is an ACE inhibitor, amlodipine is a calcium channel blocker, and losartan is an ARB.
4. **Which medication is an anticoagulant used to prevent thrombus formation?**
A. Clopidogrel
B. Warfarin
C. Aspirin
D. Tirofiban
**Answer**: B. Warfarin
**Rationale**: Warfarin inhibits vitamin K-dependent clotting factors, acting as an
anticoagulant. Clopidogrel and aspirin are antiplatelets, and tirofiban is a glycoprotein IIb/IIIa
inhibitor.
5. **What is the primary action of proton pump inhibitors (PPIs)?**
A. Neutralize gastric acid
B. Inhibit acid secretion
, C. Enhance gastric motility
D. Protect gastric mucosa
**Answer**: B. Inhibit acid secretion
**Rationale**: PPIs like omeprazole block the proton pump in parietal cells, reducing acid
secretion. Antacids neutralize acid, and other medications affect motility or mucosa.
6. **A client is prescribed nitrofurantoin for a urinary tract infection. What is its primary
action?**
A. Inhibits bacterial cell wall synthesis
B. Disrupts bacterial DNA replication
C. Inhibits bacterial protein synthesis
D. Damages bacterial cell membranes
**Answer**: B. Disrupts bacterial DNA replication
**Rationale**: Nitrofurantoin interferes with bacterial DNA, effective against urinary
pathogens. Other antibiotics target cell walls or protein
synthesis.[](https://www.docsity.com/en/docs/relias-rn-pharmacology-exam-2024-actual-exam-
questions-and-correct-answers/10678392/)
7. **Which medication is a loop diuretic?**
A. Spironolactone
B. Furosemide
C. Amiloride
D. Chlorothiazide
**Answer**: B. Furosemide
**Rationale**: Furosemide is a loop diuretic that inhibits sodium and chloride reabsorption in
the loop of Henle. Spironolactone and amiloride are potassium-sparing, and chlorothiazide is a
thiazide diuretic.
, 8. **What is the mechanism of action of metformin in type 2 diabetes?**
A. Stimulates insulin release
B. Decreases hepatic glucose production
C. Increases peripheral glucose uptake
D. Inhibits glucagon secretion
**Answer**: B. Decreases hepatic glucose production
**Rationale**: Metformin reduces gluconeogenesis in the liver, lowering blood glucose. Other
medications like sulfonylureas stimulate insulin release.
9. **A client is prescribed a statin. Which medication belongs to this class?**
A. Atorvastatin
B. Nifedipine
C. Fenofibrate
D. Ezetimibe
**Answer**: A. Atorvastatin
**Rationale**: Atorvastatin is a statin that inhibits HMG-CoA reductase, lowering cholesterol.
Nifedipine is a calcium channel blocker, fenofibrate is a fibrate, and ezetimibe inhibits
cholesterol absorption.
10. **Which medication is an angiotensin II receptor blocker (ARB)?**
A. Enalapril
B. Losartan
C. Diltiazem
D. Propranolol
**Answer**: B. Losartan
**Rationale**: Losartan blocks angiotensin II receptors, reducing blood pressure. Enalapril is
an ACE inhibitor, diltiazem is a calcium channel blocker, and propranolol is a beta-blocker.
