The patient with tuberculosis is now on isoniazid (INH). Which laboratory test should the nurse monitor?

Liver enzymes/ LFTs

PT and PTT

BUN

CBC

Answer and Explanation

The Correct Answer is A

A. Liver enzymes/ LFTs: Correct. Isoniazid (INH) is hepatotoxic and can cause liver damage. Monitoring liver function tests (LFTs) helps detect hepatotoxicity early.
B. PT and PTT: These tests measure blood clotting and are not directly affected by INH.
C. BUN: Blood Urea Nitrogen (BUN) measures kidney function, and while it is important, INH primarily affects the liver.
D. CBC: Complete Blood Count (CBC) is useful for overall health but not specifically for monitoring INH therapy.

Correct Answer is ["A","D"]

Explanation

A. Insulin: Insulin is produced by the beta cells of the pancreas and lowers blood glucose levels by facilitating the uptake of glucose into cells.
B. Growth hormone: Growth hormone is produced by the pituitary gland, not the pancreas. It can affect blood glucose levels indirectly but is not a pancreatic hormone.
C. Estrogen: Estrogen is produced primarily by the ovaries, not the pancreas. It does not directly regulate blood glucose levels.
D. Glucagon: Glucagon is produced by the alpha cells of the pancreas and raises blood glucose levels by promoting the conversion of glycogen to glucose in the liver.
E. Antidiuretic hormone: Antidiuretic hormone (ADH) is produced by the hypothalamus and released by the pituitary gland. It regulates water balance in the body, not blood glucose levels.
