A patient with Crohn's disease is experiencing diarrhea. Which dietary recommendation is appropriate?

Correct Answer: B

Rationale: A low-residue diet is appropriate for a patient with Crohn's disease experiencing diarrhea because it helps reduce bowel movements and manage symptoms. Choice A, a high-fiber diet, can exacerbate diarrhea in Crohn's disease due to increased bulk and fermentation in the gut. Choice C, a high-fat diet, may be hard to digest and can worsen symptoms. Choice D, a high-protein diet, can be taxing on the digestive system and may not provide the relief needed for diarrhea in Crohn's disease.

Correct Answer: C

Rationale: Zinc supplementation is often recommended to manage mucositis in patients undergoing chemotherapy. Zinc plays a crucial role in wound healing and immune function, which can help alleviate the symptoms of mucositis. Vitamin E (Choice A) is known for its antioxidant properties but is not typically used to manage mucositis. Vitamin B12 (Choice B) is important for red blood cell production and nerve function but is not directly associated with mucositis management. Calcium (Choice D) is essential for bone health and muscle function but is not a primary nutrient supplemented to manage mucositis.

Correct Answer: A

Rationale: The correct way to manage a patient's intake of dietary fiber is to increase it gradually. This approach helps prevent gastrointestinal discomfort that can occur when fiber intake is suddenly increased. Choice B is incorrect because sudden increases in fiber intake can lead to bloating, gas, and other digestive issues. Choice C is incorrect as decreasing fiber intake abruptly can disrupt bowel regularity and cause constipation. Choice D is incorrect because maintaining a high intake of fiber without considering the patient's current levels can also cause digestive problems.

Correct Answer: C

Rationale: The correct answer is C, GH (General Hospital), as it is the COMMZ level hospital that focuses on treating and rehabilitating patients who can return to duty within the theater evacuation policy. FSB (Forward Surgical Hospital) primarily provides surgical care close to the front lines. CSH (Combat Support Hospital) offers more comprehensive surgical and medical care than FSB but does not focus on rehabilitation like GH. FH (Field Hospital) provides initial medical care and stabilization before patients are evacuated to higher-level facilities.

Correct Answer: D

Rationale: The correct answer is D. Under the health services support area concept, medical care under MEDCOM is divided into eight geographical areas of responsibility. Each of these areas is designated as a health services support region, and they are further subdivided into two or more health service areas. Choices A, B, and C are incorrect because they do not accurately describe how the medical care under MEDCOM is divided.
