GRADED A+ | ASSURED SUCCESS WITH DETAILED RATIONALES
Question 1
A nurse is monitoring a client taking carbamazepine (Tegretol). Which serum level indicates a
therapeutic range?
A. 1–5 mcg/mL
B. 3–8 mcg/mL
C. 5–12 mcg/mL
D. 15–25 mcg/mL
✅Correct Answer: C. 5–12 mcg/mL
Rationale:
Therapeutic range for carbamazepine is 5–12 mcg/mL. Levels above this increase risk of
toxicity (ataxia, diplopia, CNS depression).
Question 2
A client is receiving digoxin (Lanoxin). Which level indicates therapeutic effect?
A. 0.1–0.5 ng/mL
B. 0.5–2.0 ng/mL
C. 2.5–4.0 ng/mL
D. 5–10 ng/mL
✅Correct Answer: B. 0.5–2.0 ng/mL
Rationale:
Digoxin has a narrow therapeutic index. Levels above 2.0 increase risk of toxicity
(bradycardia, visual disturbances).
Question 3
Which laboratory value reflects a therapeutic peak level for gentamicin?
A. 1–3 mcg/mL
B. 3–5 mcg/mL
,C. 5–10 mcg/mL
D. 12–20 mcg/mL
✅Correct Answer: C. 5–10 mcg/mL
Rationale:
Gentamicin therapeutic peak = 5–10 mcg/mL. Higher levels risk nephrotoxicity and
ototoxicity.
Question 4
A nurse is reviewing phenytoin levels. Which result indicates therapeutic range?
A. 2–5 mcg/mL
B. 5–10 mcg/mL
C. 10–20 mcg/mL
D. 25–40 mcg/mL
✅Correct Answer: C. 10–20 mcg/mL

B. 5–10 mcg/mL
C. 10–20 mcg/mL
D. 25–35 mcg/mL
✅Correct Answer: C. 10–20 mcg/mL
Question 6
