Occasional use of nitroglycerin
Benign prostatic hypertrophy
Mild hypertension

Correct Answer is A
Explanation
a. This is the correct answer because maintaining adequate hydration helps prevent nephrotoxicity associated with acyclovir. Encouraging fluid intake during and after the infusion helps flush the drug through the kidneys.
b. While monitoring urinary output is important, it alone may not be sufficient to prevent nephrotoxicity.
c. Providing a low-protein diet is not a standard intervention for preventing acyclovir-induced nephrotoxicity.
d. Administering intravenous normal saline boluses, as ordered, can help maintain hydration and prevent nephrotoxicity. However, encouraging oral fluid intake is a more direct and immediate measure during acyclovir infusion.
Correct Answer is B
Explanation
a) Levothyroxine is usually recommended to be taken 30 to 60 minutes before breakfast to enhance absorption, but this is not the answer indicated by the client's statement.
b) Taking levothyroxine at bedtime is another acceptable option and may be more convenient for some individuals. Both options (morning or bedtime) are valid.
c) Taking levothyroxine when feeling fatigued is not a specific guideline for medication administration.
d) Taking levothyroxine with an antacid may interfere with absorption and is not recommended.
