A client ordered grapefruit juice for breakfast. The nurse should review the client's medication record for medications metabolized by the:
Gall bladder
Liver
Kidney
Small bowel
The Correct Answer is B
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. Sodium 126 mEq/L: This value indicates hyponatremia, which can cause confusion, seizures, and fluid imbalance. Normal sodium levels are 135-145 mEq/L, so this is a critical finding.
B. Chloride 99 mmol/L: This is within the normal range (96-106 mmol/L), so it is not concerning.
C. Albumin 4.9 mg/dL: Normal albumin levels are 3.5-5.0 mg/dL, so this value is within range.
D. Potassium 3.6 mEq/L: Normal potassium levels are 3.5-5.0 mEq/L. This value is on the lower end but still within normal limits.
