SECTION 1: DRUG CLASSIFICATIONS & MECHANISMS OF ACTION
1. A nurse is preparing to administer furosemide to a client with heart failure. To which drug
class does furosemide belong?
A) Beta-blocker
B) Loop diuretic
C) ACE inhibitor
D) Calcium channel blocker
**Rationale: Furosemide is a loop diuretic that promotes diuresis by inhibiting sodium and
chloride reabsorption in the thick ascending limb of the loop of Henle. This reduces fluid
overload in heart failure .
2. A nurse is administering lisinopril to a client. What is the primary indication for this
medication?
A) Pain relief
B) Seizure control
C) Hypertension
D) Infection treatment
**Rationale: Lisinopril is an ACE inhibitor primarily used to treat hypertension and heart
failure. It works by inhibiting the conversion of angiotensin I to angiotensin II, reducing
vasoconstriction and aldosterone secretion .
3. A nurse is administering atorvastatin. To which drug class does it belong?
A) Anticoagulant
B) Statin
C) Beta-agonist
D) Antidepressant
, **Rationale: Atorvastatin is a statin that lowers cholesterol by inhibiting HMG-CoA
reductase in the liver. This reduces LDL cholesterol and decreases the risk of
cardiovascular events .
4. Which antifungal drug is correctly matched with its mechanism of action?
A) Echinocandins inhibit polysaccharide (glucan) synthesis in the cell wall
B) Flucytosine binds to the cell membrane
C) Ticonazole is an antimetabolite for fungal RNA
D) Amphotericin B binds to a cytochrome P450-dependent enzyme
**Rationale: Echinocandins (e.g., caspofungin) inhibit glucan synthesis in the fungal cell
wall. Amphotericin B binds to ergosterol in the fungal cell membrane. Azoles inhibit
cytochrome P450 enzymes .
5. The mechanism of action for antiviral medications may include:
A) Changing cell-wall synthesis
B) Binding to ergosterol
C) Inhibiting cell mitosis
D) Inhibiting neuraminidase
**Rationale: Neuraminidase inhibitors (e.g., oseltamivir) block the neuraminidase
enzyme, preventing viral release from infected cells. This is a key mechanism for influenza
antivirals .
6. A client is prescribed albuterol for asthma. Which drug classification does albuterol
belong to?
A) Corticosteroid
B) *Beta-2 adrenergic agonist*
C) Anticholinergic
D) Leukotriene receptor antagonist
***Rationale: Albuterol is a short-acting beta-2 adrenergic agonist (SABA) that causes
bronchodilation by relaxing smooth muscle in the airways. It is first-line for acute asthma
exacerbations .*
7. Which drug classification is used to treat anaphylaxis?
A) Antihistamines alone
B) Epinephrine – sympathomimetic
, C) Corticosteroids
D) Bronchodilators
**Rationale: Epinephrine is a sympathomimetic (alpha and beta agonist) that reverses
bronchospasm, hypotension, and mucosal edema in anaphylaxis. It is first-line treatment .
8. A nurse is caring for a client taking atenolol. Atenolol belongs to which drug class?
A) Calcium channel blocker
B) Beta-adrenergic blocker
C) ACE inhibitor
D) Vasodilator
***Rationale: Atenolol is a cardioselective beta-1 adrenergic blocker that reduces heart
rate, contractility, and blood pressure by blocking beta-adrenergic receptors in the heart .*
9. Which medication classification is used to treat hypercalcemia?
A) Calcium chloride
B) Calcium gluconate
C) Calcitonin
D) Vitamin D
**Rationale: Calcitonin decreases plasma calcium levels by inhibiting bone resorption and
increasing renal calcium excretion. It is used for hypercalcemia, including that caused by
malignancy or hyperparathyroidism .
10. The site of action of diazepam (Valium) to relieve anxiety is the:
A) Spinal cord
B) Limbic system
C) Reticular formation
D) Basal ganglia
**Rationale: Benzodiazepines like diazepam act on the limbic system, which regulates
emotion and anxiety. They enhance GABA activity, producing anxiolytic effects .
11. Saquinavir (Invirase) is classified as which type of medication?
A) Antifungal
B) Protease inhibitor (antiretroviral)
C) Anticoagulant
