A nurse is reviewing the medical record of a client who has beers taking a medication that can cause hepatoxicity. Which of the following data should the nurse report to the provider?
HbA1C 5.9%
Albumin 3.8 g/dl
Alanine aminotransferase (ALT) 67 units/l
Aspartate aminotransferase (AST) 39 units/l
The Correct Answer is C
Here is the rationale for each choice:
A. HbA1C 5.9%: HbA1C is a measure of long-term glucose control in patients, often used in diabetes management. A value of 5.9% is slightly above the normal range (4–5.7%) but does not indicate hepatotoxicity.
B. Albumin 3.8 g/dl: Albumin is a protein produced by the liver, and its levels can reflect liver function. A normal range is 3.5–5 g/dl, and 3.8 g/dl falls within this range. Thus, it does not indicate hepatotoxicity.
C. Alanine aminotransferase (ALT) 67 units/l: ALT is an enzyme primarily found in the liver and is a key marker for liver injury. The normal range for ALT is approximately 7–56 units/l. A value of 67 units/l is slightly elevated, which may suggest mild liver damage or hepatotoxicity. This result should be reported to the provider, as it could be associated with the medication’s impact on the liver.
D. Aspartate aminotransferase (AST) 39 units/l: AST is another enzyme used to evaluate liver function, though it is less specific to the liver than ALT, as AST is also found in other tissues such as the heart and muscles. The normal range for AST is roughly 10–40 units/l.

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.
Correct Answer is ["22"]
Explanation
- 1 inch = 2.54 cm
- 55 cm ÷ 2.54 cm/inch ≈ 21.65 inches
- Rounded to the nearest whole number = 22 inches
