Correct Answer: C

Rationale: Ambulance exchange points are set up when threats to air resources make it impossible to evacuate by air from forward units. These points serve as locations where patients can be transferred from ambulances to aircraft for further evacuation. Area support medical battalions (Choice A) are not directly related to this scenario, as they provide medical support to larger areas. TOE units (Choice B) refer to tables of organization and equipment, not specific to this situation. Field hospitals (Choice D) are more permanent facilities for treating patients and are not specifically for transferring patients under threats to air resources.

Correct Answer: A

Rationale: The correct answer is A because tapering glucocorticoids is crucial to prevent adrenal insufficiency, which can occur if the medication is stopped abruptly. Choice B is incorrect as it refers to dose adjustments during stress or infection, not discontinuation. Choice C is incorrect because it does not specifically address the issue of stopping the medication. Choice D is not directly related to the management of glucocorticoid therapy for Addison's disease.

Correct Answer: C

Rationale: The correct answer is C: Elevate the circulating blood volume. Albumin increases the circulating blood volume, which helps to reduce ascites and improve hemodynamics in clients with portal hypertension. Choice A is incorrect because salt-poor albumin is not primarily administered to provide nutrients. Choice B is incorrect because the main purpose of administering albumin is not to increase protein stores but to address fluid shifts. Choice D is incorrect because administering albumin does not divert blood flow away from the liver temporarily; instead, it helps improve blood volume and circulation.

Correct Answer: C

Rationale: Ambulance exchange points are established when threats to air resources prevent evacuation by air from forward units. These points serve as locations where patients can be transferred between ground and air ambulances. Area support medical battalions (Choice A) refer to medical units that provide medical support to large areas and are not specifically related to evacuation. TOE units (Choice B) and field hospitals (Choice D) are not typically established in response to threats to air resources affecting evacuation.

Correct Answer: D

Rationale: The correct answer is D, Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates the bone marrow to produce red blood cells. Choices A, B, and C are incorrect. Iron-deficiency anemia is characterized by low iron levels, vitamin B12 deficiency anemia by inadequate vitamin B12, and aplastic anemia by bone marrow failure.
