Explanation
B. Liver: Grapefruit juice inhibits CYP3A4 enzymes in the liver, which metabolize many drugs (e.g., statins, calcium channel blockers). This inhibition can lead to increased drug levels and toxicity.
A. Gall bladder – The gall bladder stores bile but does not metabolize drugs.
C. Kidney – The kidneys excrete drugs, but grapefruit juice does not significantly impact renal metabolism.
D. Small bowel – Some drug metabolism occurs in the intestines, but grapefruit juice primarily affects liver enzymes.
Correct Answer is A
Explanation
A. 1630 and 1930: Peak and trough levels are used to monitor drug effectiveness and prevent toxicity. Trough levels (lowest drug concentration) are drawn right before the next dose-1745 would be slightly too late. Peak levels (highest drug concentration) are drawn 30-60 minutes after administration (for IV drugs). Since the next dose is at 1800, the trough should be drawn just before the dose (1630) and the peak should be drawn 30-60 minutes after the dose (1930).
B. 1100 and 1700- Incorrect timing, not close to dose administration.
C. 1400 and 2200- Too far from the scheduled 1800 dose.
D. 1745 and 1830- Trough is too close to administration, peak is too early.
