1. Which pharmacologic principle describes how a drug is absorbed, distributed,
metabolized, and excreted by the body?
Page | 2
1. Pharmacodynamics
✔ 2. Pharmacokinetics
2. Half-life
3. Therapeutic range
Answer: 2
Rationale: Pharmacokinetics involves the movement of drugs through the body, including
absorption, distribution, metabolism, and excretion. It determines how long a drug stays
active in the system and influences dosing intervals and onset of action. This differs from
pharmacodynamics, which focuses on the drug’s biological effect. Understanding
pharmacokinetics helps nurses anticipate therapeutic and adverse effects.
2. Which lab result is most important to monitor in a patient receiving lisinopril?
1. Blood glucose
2. BUN
✔ 3. Serum potassium
3. Platelet count
Answer: 3
Rationale: Lisinopril, an ACE inhibitor, can cause retention of potassium and hyperkalemia.
Monitoring serum potassium is essential, especially in clients with renal impairment or those
taking potassium-sparing diuretics. Hyperkalemia can lead to serious cardiac complications
, 3
such as arrhythmias. While BUN and creatinine are also relevant, potassium levels provide
the most immediate insight into possible adverse effects.

3. A client with heart failure is prescribed digoxin. Which finding should the nurse
report immediately?
1. Apical heart rate of 64 bpm
✔ 2. Visual disturbances such as yellow halos
2. Mild fatigue
3. Blood pressure of 130/80 mmHg
Answer: 2
Rationale: Visual disturbances, particularly seeing yellow or green halos around lights, are
classic signs of digoxin toxicity. Digoxin has a narrow therapeutic range, and toxicity can
lead to life-threatening arrhythmias. Although fatigue is common in heart failure, visual
changes are an early warning sign that the drug may need to be held and serum digoxin levels
checked immediately.
4. Which statement by a client taking warfarin indicates a need for further teaching?
1. “I’ll avoid aspirin unless prescribed.”
✔ 2. “I will increase my intake of leafy green vegetables.”
2. “I’ll use a soft-bristle toothbrush.”
3. “I will get my INR checked regularly.”
, 4
Answer: 2
Rationale: Leafy green vegetables are high in vitamin K, which can counteract the effects of
warfarin and reduce its anticoagulant properties. Clients should maintain a consistent intake
Page | 4
rather than suddenly increasing it. All other statements reflect appropriate safety behaviors.
This question tests the nurse’s ability to assess client understanding and reinforce essential
dietary restrictions with anticoagulants.
5. What is the priority nursing action when administering IV potassium chloride?
✔ 1. Use an infusion pump and dilute the solution
2. Administer via IV push
3. Mix with dextrose 5% for rapid absorption
4. Give the dose undiluted if patient is hypokalemic
Answer: 1
Rationale: IV potassium chloride should never be given as an IV push or undiluted. It must
be diluted and administered slowly using an infusion pump to prevent life-threatening
arrhythmias. Administering potassium too quickly can lead to cardiac arrest. The nurse must
ensure appropriate dilution and rate of administration to maintain client safety and meet
standard of care.
6. Which medication requires monitoring for ototoxicity?
1. Metronidazole
