Section I: Autonomic Agents
1. A client is experiencing symptomatic bradycardia.
Which medication should the nurse prepare?
A. Atropine
B. Propranolol
C. Metoprolol
D. Bethanechol
Answer: A. Atropine
Rationale: Atropine blocks muscarinic receptors,
inhibiting parasympathetic stimulation of the heart and
increasing heart rate (NursingTip).
2. A patient with asthma is prescribed albuterol.
Which statement indicates understanding?
A. “I will use it before exercise.”
B. “It will decrease mucus production.”
C. “It blocks beta-1 receptors.”
D. “I should take it with meals.”
Answer: A. “I will use it before exercise.”
Rationale: Albuterol is a β₂-agonist that
bronchodilates and is often used prophylactically
before exertion (Studocu).
3. Which drug would be contraindicated in a client
taking a nonselective β-blocker?
A. Atenolol
B. Metoprolol
C. Propranolol
D. Albuterol
, Answer: D. Albuterol
Rationale: Propranolol blocks both β₁ and β₂
receptors; using albuterol (a β₂-agonist) can be
antagonized and exacerbate bronchospasm
(Studocu).
4. For urinary retention following surgery, the nurse
anticipates administering:
A. Bethanechol
B. Neostigmine
C. Atropine
D. Oxybutynin
Answer: A. Bethanechol
Rationale: Bethanechol is a muscarinic agonist that
stimulates bladder contraction (NursingTip).
5. A patient on atropine should be monitored for
which adverse effect?
A. Diaphoresis
B. Urinary retention
C. Bradycardia
D. Diarrhea
Answer: B. Urinary retention
Rationale: Antimuscarinic effects include decreased
bladder tone leading to retention (NursingTip).
Section II: Cardiovascular Drugs
6. Which medication is first-line for acute angina
relief?
A. Metoprolol
, B. Nitroglycerin sublingual
C. Diltiazem
D. Lisinopril
Answer: B. Nitroglycerin sublingual
Rationale: Rapidly reduces preload via venous
dilation to relieve chest pain (Naxlex).
7. A client on furosemide should be monitored for:
A. Hyperkalemia
B. Hypokalemia
C. Hypertension
D. Bradycardia
Answer: B. Hypokalemia
Rationale: Loop diuretics increase K⁺ excretion,
risking hypokalemia (Naxlex).
8. Which antihypertensive drug is contraindicated in
pregnancy?
A. Methyldopa
B. Labetalol
C. Enalapril
D. Hydralazine
Answer: C. Enalapril
Rationale: ACE inhibitors cause fetal renal damage
and are contraindicated (Naxlex).
9. For dysrhythmias, amiodarone’s primary action is
to:
A. Block calcium channels
B. Prolong repolarization
