Correct Answer: D

Rationale: The correct answer is D because a recent illness, such as a cold, can trigger a vaso-occlusive crisis in sickle cell disease. This crisis is often precipitated by infections or other illnesses that cause a systemic inflammatory response, leading to vaso-occlusion. Choices A, B, and C do not directly relate to the etiology of a vaso-occlusive crisis in sickle cell disease, making them incorrect.

Correct Answer: B

Rationale: Checking the client's gag reflex is the appropriate action in this scenario. It helps assess the client's ability to swallow safely without the risk of aspiration. Adding a thickening agent to the fluids (Choice A) may be considered later if swallowing difficulties persist. Feeding the client only solid foods (Choice C) can increase the risk of aspiration in this case, and increasing the rate of intravenous fluids (Choice D) does not address the swallowing concern.

Correct Answer: A

Rationale: Corrected Rationale: Yogurt contains all essential amino acids, making it a complete protein. Choice B, fresh vegetables, are incomplete proteins.

Correct Answer: B

Rationale: The correct answer is B because a positive acid-fast bacillus smear in an elderly factory worker suggests tuberculosis, a serious communicable disease that must be reported promptly to the public health department to prevent its spread. Choice A is incorrect as Shigella is an important pathogen, but it does not require immediate public health reporting. Choice C is incorrect because Pneumocystis carinii is an opportunistic pathogen and does not require urgent public health reporting. Choice D is incorrect as varicella-zoster virus causes chickenpox and shingles, both of which are not reportable diseases to the public health department.

Correct Answer: C

Rationale: The correct answer is C: Beans. Beans are an excellent choice for individuals following a low-cholesterol diet post-coronary artery bypass grafting due to their low cholesterol content.

Choice B, Milk, contains cholesterol and saturated fats, which are not ideal for this diet. Choice D, Eggs, are also high in cholesterol and should be limited in a low-cholesterol diet.
