Correct Answer: C

Rationale: The correct answer is C: Fat-soluble vitamins. Neomycin is known to interfere with the absorption of fat-soluble vitamins. This is because neomycin can disrupt the normal gut flora responsible for the absorption of these vitamins. Choices A, B, and D are incorrect because neomycin primarily affects the absorption of fat-soluble vitamins, not minerals, proteins, amino acids, or water-soluble vitamins.

Correct Answer: B

Rationale: The correct answer is B: Decreased urine output. When vegetative lesions from the mitral valve embolize, they can block blood flow to the kidneys, leading to renal infarction. This can result in decreased urine output. Choices A, C, and D are incorrect. Pulmonary embolism involves a blockage of an artery in the lungs, not directly related to embolization from the mitral valve. Hemoptysis is the coughing up of blood from the respiratory tract, which is not a direct consequence of embolization from the mitral valve. Deep vein thrombosis is the formation of a blood clot in a deep vein, unrelated to embolization from the mitral valve.

Correct Answer: D

Rationale: The correct answer is D. Avoiding irritants like spicy foods, tobacco, and alcohol is crucial in managing mouth ulcers as they can further irritate and worsen the condition. Choice A is incorrect as using a soft-bristle toothbrush may still cause discomfort. Choice B is incorrect as alcohol-containing mouthwashes can be irritating. Choice C is incorrect as swallowing antifungal solution meant for topical use is not appropriate and can be harmful.

Correct Answer: D

Rationale: The correct answer is D. Avoiding irritants like spicy foods, tobacco, and alcohol is crucial in managing mouth ulcers as they can further irritate the ulcers and delay healing. Choices A, B, and C could potentially worsen the condition. Brushing with a soft-bristle toothbrush may cause discomfort, rinsing with Listerine mouthwash can be too harsh on the ulcers, and swallowing antifungal solution is not recommended unless specified by a healthcare provider.

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.
