Deep vein thrombosis
Hemorrhage
Peripheral neuropathy
Achilles tendon rupture
The Correct Answer is C
A. Incorrect: Deep vein thrombosis (DVT) is not a known complication of isoniazid.
B. Incorrect: Hemorrhage is not associated with isoniazid.
C. Correct: Isoniazid can cause peripheral neuropathy due to vitamin B6 (pyridoxine) deficiency. Clients experiencing numbness and tingling should be assessed for neuropathy and may need pyridoxine supplementation.

Correct Answer is D
Explanation
A. Incorrect: 1130 is too late for an accurate peak level.
B. Incorrect: 1100 is later than necessary for a peak level.
C. Incorrect: 1000 is when the infusion ends, but the drug has not yet reached peak levels in the blood.
D. Correct: Gentamicin peak levels are typically measured 30 minutes after the infusion is completed. Since the infusion starts at 0900 and runs for 60 minutes (until 1000), the peak level should be drawn at 1030.
