Correct Answer: C

Rationale: Norepinephrine is indeed secreted by the adrenal medulla, making choice C the correct answer. The adrenal medulla is part of the adrenal glands, located on top of the kidneys. Norepinephrine is involved in the body's 'fight or flight' response, helping to prepare the body to react to stress. Choices A, B, and D are incorrect as norepinephrine is not secreted by the pancreas, adrenal cortex, or the anterior pituitary gland.

Correct Answer: C

Rationale: The correct answer is C. Neomycin can interfere with the absorption of fat-soluble vitamins such as vitamins A, D, E, and K. Choice A is incorrect because neomycin does not affect the absorption of iron, copper, and zinc. Choice B is incorrect as neomycin does not impact the absorption of protein and amino acids. Choice D is also incorrect as neomycin does not decrease the absorption of water-soluble vitamins like vitamin C and the B vitamins.

Correct Answer: C

Rationale: Choice C indicates that further teaching is needed because taking a laxative every night and aiming to have a stool daily can lead to dependence and is not recommended for managing hemorrhoids. Choices A, B, and D are appropriate self-care measures for hemorrhoids, such as increasing fiber intake, using warm compresses/sitz baths, and using analgesic ointments or suppositories for pain relief.

Correct Answer: C

Rationale: The correct answer is C: GH (General Hospital). General Hospitals have the principal mission of treating and rehabilitating patients who can return to duty within the theater evacuation policy. FSB (Forward Surgical Hospital), CSH (Combat Support Hospital), and FH (Field Hospital) do not focus on treating and rehabilitating patients for duty within the theater evacuation policy, making them incorrect choices.

Correct Answer: B

Rationale: The correct answer is 'Decreased urine output.' Embolization of vegetative lesions from the mitral valve can cause renal infarction, leading to a decrease in urine output. This complication is due to the obstruction of blood flow to the kidneys. Choices A, C, and D are incorrect because embolization from the mitral valve typically does not directly cause pulmonary embolism, hemoptysis, or deep vein thrombosis.
