Introduction
This comprehensive practice examination is designed to rigorously assess your knowledge and clinical
application of pharmacotherapeutics in preparation for the NSG 1540 final exam. It covers foundational
theory, drug mechanisms, side effect profiles, and complex patient management scenarios. The 200
multiple-choice questions are crafted to evaluate critical thinking, decision-making, and the safe
application of pharmacological principles in real-world settings. Emphasis is placed on interpreting
clinical data, understanding drug interactions, and adhering to legal and ethical standards. This resource
is intended to solidify your understanding and build confidence for success on your final examination.
SECTION ONE: QUESTIONS 1 – 100
1. A patient is prescribed a medication that acts as a competitive antagonist at muscarinic receptors.
Which of the following physiological effects would the nurse expect to observe?
A. Miosis
B. Bradycardia
C. Bronchoconstriction
D. Decreased gastrointestinal motility
🟢 D. Decreased gastrointestinal motility
,🔴 Explanation: A competitive antagonist at muscarinic receptors (like atropine) will block the
parasympathetic effects of acetylcholine. This leads to mydriasis (pupil dilation), tachycardia,
bronchodilation, and decreased GI motility. Therefore, decreased GI motility is the correct expected
effect.
2. A patient with a history of angina is prescribed isosorbide dinitrate. The nurse explains that the
therapeutic effect of this drug is primarily due to which mechanism?
A. Blockade of beta-1 adrenergic receptors in the heart
B. Inhibition of calcium influx into vascular smooth muscle
C. Conversion to nitric oxide, leading to vasodilation
D. Inhibition of angiotensin-converting enzyme
🟢 C. Conversion to nitric oxide, leading to vasodilation
🔴 Explanation: Isosorbide dinitrate is an organic nitrate. Its mechanism of action involves being
converted to nitric oxide (NO) in the body, which then stimulates guanylate cyclase, increasing cGMP
and causing relaxation of vascular smooth muscle, particularly in veins, leading to vasodilation and
reduced cardiac workload.
3. A nurse is monitoring a patient receiving an IV infusion of dopamine. Which assessment finding
would indicate a desired therapeutic effect?
A. Decreased cardiac output
B. Decreased mean arterial pressure
C. Increased urine output
D. Increased systemic vascular resistance
🟢 C. Increased urine output
🔴 Explanation: At low to moderate doses, dopamine stimulates dopamine-1 receptors in the renal
vasculature, leading to vasodilation and increased renal blood flow, which results in increased urine
output. This is a desired therapeutic effect in patients with shock or renal failure.
4. A patient is started on sertraline. The nurse should instruct the patient that the full therapeutic
effect for depression may not be realized for:
A. 1 to 2 days
B. 3 to 5 days
,C. 1 to 2 weeks
D. 4 to 8 weeks
🟢 D. 4 to 8 weeks
🔴 Explanation: Selective serotonin reuptake inhibitors (SSRIs) like sertraline require several weeks to
achieve their full antidepressant effect. While some improvement may be seen in 1-2 weeks, the full
therapeutic benefit often takes 4 to 8 weeks to manifest.
5. A patient on warfarin therapy has an INR of 1.2. The nurse anticipates an order for:
A. An increase in the warfarin dose
B. A decrease in the warfarin dose
C. Discontinuation of the warfarin
D. Administration of vitamin K
🟢 A. An increase in the warfarin dose
🔴 Explanation: The therapeutic INR range for most indications is 2.0-3.0. An INR of 1.2 is
subtherapeutic, indicating that the patient is not adequately anticoagulated. The healthcare provider
would likely order an increase in the warfarin dose to achieve a therapeutic level.
6. A patient with asthma is prescribed a leukotriene receptor antagonist. The nurse knows this
medication is MOST beneficial for which type of asthma?
A. Exercise-induced bronchospasm
B. Acute severe asthma exacerbation
C. Status asthmaticus
D. Allergic rhinitis-induced asthma
🟢 D. Allergic rhinitis-induced asthma
🔴 Explanation: Leukotriene receptor antagonists (e.g., montelukast) are particularly effective in
patients with allergic asthma or asthma exacerbated by allergic rhinitis. They are not effective for acute
asthma exacerbations and are used as prophylactic therapy.
7. The nurse is preparing to administer a drug that is highly protein-bound. The patient's serum
albumin level is low. The nurse should monitor the patient for which effect?
, A. Decreased drug efficacy
B. Increased risk of drug toxicity
C. Decreased drug half-life
D. Increased renal excretion
🟢 B. Increased risk of drug toxicity
🔴 Explanation: Low serum albumin means there are fewer binding sites for the drug. A higher
concentration of unbound (free) drug is present, which is pharmacologically active. This increases the
risk of toxicity, as there is more drug available to exert its effect.
8. A patient is prescribed a beta-blocker. Which adverse effect is MOST concerning in a patient with
a history of COPD?
A. Tachycardia
B. Hypotension
C. Bronchospasm
D. Headache
🟢 C. Bronchospasm
🔴 Explanation: Non-selective beta-blockers (like propranolol) can block beta-2 receptors in the lungs,
leading to bronchospasm. Even cardioselective beta-blockers (like metoprolol) are used with caution in
COPD patients. Bronchospasm is the most concerning effect because it can exacerbate COPD
symptoms and lead to respiratory distress.
9. A nurse is caring for a patient receiving vancomycin IV. Which assessment is MOST important to
perform during the infusion?
A. Monitoring for a red rash on the trunk
B. Monitoring for a "red man syndrome"
C. Monitoring blood pressure for hypertension
D. Monitoring for Chvostek's sign
🟢 B. Monitoring for a "red man syndrome"
🔴 Explanation: Rapid IV infusion of vancomycin can cause "red man syndrome," characterized by a
histamine-like reaction causing flushing, rash, and hypotension. Monitoring for this side effect and
ensuring the infusion is given over at least 60 minutes are crucial nursing interventions.
