Questions & Verified Answers
1. Which factor is the most important determinant of a drug’s ability to cross the blood-brain
barrier?
A. Molecular weight of the drug
B. Protein binding affinity
C. Degree of ionization
D. Lipid solubility
Answer: D
Rationale: To cross the blood-brain barrier, a drug must be highly lipid-soluble to pass through the
capillary endothelial cells of the brain, as there are no slits between these cells. Clear understanding of
this concept improves both test performance and everyday clinical judgment. Practice applying it to
short case scenarios to lock the idea in place. Understanding this helps the nurse notice early warning
signs and act before the problem gets worse. Early action often prevents bigger complications for the
client.
2. A patient is taking a drug that is a known CYP450 enzyme inducer. How will this affect a
co- administered drug that is metabolized by the same enzyme system?
A. It will increase the plasma levels of the second drug.
B. It will decrease the rate of metabolism of the second drug.
C. It will have no effect on the second drug.
D. It will decrease the plasma levels of the second drug.
Answer: D
Rationale: Enzyme inducers increase the metabolic activity of CYP450 enzymes, leading to faster
breakdown and lower plasma levels of substrate drugs. Remembering this point will help you decide
the best nursing action when similar questions appear on the exam. Link the answer to the client’s
current condition and risk level. Exam questions often test whether you can pick the most practical and
safe choice for the client in real situations. Focus on what the nurse can actually do right now.

3. When initiating ACE inhibitor therapy, which laboratory value must be monitored most
closely for potential elevation?
A. Serum Sodium
B. Blood Urea Nitrogen
C. Serum Calcium
D. Serum Potassium
Answer: D
Rationale: ACE inhibitors reduce aldosterone secretion, which can lead to potassium retention and
hyperkalemia. Remembering this point will help you decide the best nursing action when similar
questions appear on the exam. Link the answer to the client’s current condition and risk level. Clear
understanding of this concept improves both test performance and everyday clinical judgment.
Practice applying it to short case scenarios to lock the idea in place.
4. A 75-year-old patient has a reduced glomerular filtration rate (GFR). What adjustment is
typically required for drugs excreted renally?
A. Increase the dosage
B. Decrease the dosage or increase the dosing interval
C. Decrease the dosing interval
D. Switch to a drug with a shorter half-life
Answer: B
Rationale: Reduced renal function decreases clearance, necessitating lower doses or longer intervals
between doses to prevent toxicity. This is important because the nurse must choose the action that
keeps the client safest while still meeting their basic needs. Always think about safety first when
answering these questions. Remembering this point will help you decide the best nursing action when
similar questions appear on the exam. Link the answer to the client’s current condition and risk level.
