Introduction
This comprehensive practice assessment is designed to evaluate and enhance the clinical competency of nursing students and professionals in the field of pharmacology. The exam
assesses a candidate's ability to integrate physiological principles with drug actions, ensuring safe patient outcomes. Through a series of multiple-choice and complex scenario-based
questions, the assessment tests knowledge of drug classifications, adverse effects, and nursing interventions. With a strong emphasis on real-world application, legal compliance, and
ethical decision-making, this tool prepares learners to navigate the intricate responsibilities of medication management in diverse healthcare settings, fostering critical thinking and
precision in practice.
1. A nurse is preparing to administer digoxin to a patient with heart failure. Which of the following actions should the nurse take first?
A. Weigh the patient.
B. Check the patient's serum potassium level.
C. Assess the apical pulse for one full minute.
D. Monitor the patient's blood pressure.
🟢 C. Assess the apical pulse for one full minute.
🔴 RATIONALE: Digoxin is a cardiac glycoside that decreases the heart rate. The nurse must assess the apical pulse for 60 seconds; if the heart rate is less than 60 beats per
minute, the dose is typically held to prevent bradycardia.
, 2. A patient is prescribed sublingual nitroglycerin for angina. What instruction should the nurse include in the teaching?
A. Swallow the tablet with a full glass of water.
B. Place the tablet under the tongue and let it dissolve completely.
C. Take the medication only if chest pain lasts longer than 30 minutes.
D. Crush the tablet and mix it with food if it tastes bitter.
🟢 B. Place the tablet under the tongue and let it dissolve completely.
🔴 RATIONALE: Sublingual medications bypass the first-pass metabolism by absorbing directly into the systemic circulation through the oral mucosa. Swallowing or crushing the
medication would significantly reduce its effectiveness.
3. Which laboratory value is most important for a nurse to monitor in a patient receiving heparin via continuous IV infusion?
A. Prothrombin time (PT)
B. International Normalized Ratio (INR)
C. Activated partial thromboplastin time (aPTT)
D. Platelet count
🟢 C. Activated partial thromboplastin time (aPTT)
🔴 RATIONALE: The aPTT is the standard laboratory test used to monitor the effectiveness and safety of heparin therapy. PT and INR are typically used to monitor warfarin
therapy.
4. A nurse is caring for a patient who has a new prescription for lisinopril. The nurse should monitor the patient for which of the following adverse effects?
A. Hyperkalemia
B. Hypokalemia
C. Tachycardia
D. Weight gain
🟢 A. Hyperkalemia
🔴 RATIONALE: ACE inhibitors like lisinopril can cause potassium retention by inhibiting aldosterone secretion. Patients should be monitored for elevated potassium levels and
advised to avoid salt substitutes containing potassium.
5. A patient with type 1 diabetes mellitus is prescribed lispro insulin. When should the nurse administer this medication?
A. 30 to 60 minutes before a meal.
B. Immediately after a meal.
C. 15 minutes before a meal.
D. At bedtime.
, 🟢 C. 15 minutes before a meal.
🔴 RATIONALE: Lispro is a rapid-acting insulin with an onset of 15 minutes. It must be administered shortly before eating to prevent hypoglycemia and to match the
postprandial glucose spike.
6. Which medication is considered the antidote for an overdose of warfarin?
A. Protamine sulfate
B. Vitamin K
C. Naloxone
D. Acetylcysteine
🟢 B. Vitamin K
🔴 RATIONALE: Vitamin K antagonizes the effects of warfarin by promoting the synthesis of clotting factors. Protamine sulfate is the antidote for heparin, and naloxone is for
opioids.
7. A nurse is teaching a patient about a new prescription for albuterol inhaler. Which statement by the patient indicates an understanding of the teaching?
A. I should use this medicine to prevent an asthma attack every morning.
B. I will use this inhaler when I feel short of breath or wheezing.
C. I should rinse my mouth with water before using the inhaler.
D. This medication might make me feel very sleepy.
🟢 B. I will use this inhaler when I feel short of breath or wheezing.
🔴 RATIONALE: Albuterol is a short-acting beta2-agonist (SABA) used as a rescue medication for acute bronchospasm. It is not used for long-term daily prevention
(maintenance).
8. A patient is receiving furosemide for peripheral edema. Which of the following foods should the nurse encourage the patient to consume?
A. White bread
B. Bananas
C. Canned soup
D. Cheese
🟢 B. Bananas
🔴 RATIONALE: Furosemide is a loop diuretic that causes the excretion of potassium. To prevent hypokalemia, patients should increase their intake of potassium-rich foods like
bananas, spinach, and potatoes.
9. A nurse is reviewing the medication record of a patient who has a prescription for spironolactone. Which of the following medications, if taken concurrently, increases the
risk for hyperkalemia?
