Correct Answer: A

Rationale: The correct answer is A, Tomato juice. Tomato juice is high in vitamin C, which enhances the absorption of nonheme iron from foods. Vitamin C helps convert nonheme iron to a form that is easier for the body to absorb. Tea (choice B) contains tannins that can inhibit iron absorption. Milk (choice C) contains calcium, which can interfere with iron absorption. Dried beans (choice D) are a good source of nonheme iron but do not enhance iron absorption when consumed with nonheme iron.

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: The correct answer is B: Potassium. Spironolactone is a potassium-sparing diuretic, which means it helps retain potassium while eliminating sodium. This is beneficial for patients with cirrhosis and ascites as they are at risk of low potassium levels. Choice A, Sodium, is incorrect as Spironolactone does not spare the elimination of sodium but rather helps eliminate it. Choice C, Phosphate, is incorrect as Spironolactone does not directly affect phosphate levels. Choice D, Albumin, is incorrect as Spironolactone does not spare the elimination of albumin.

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: D

Rationale: The correct answer is 'D: Activity intolerance related to fatigue.' This nursing diagnosis should receive the highest priority for a client with hyperthyroidism. Hyperthyroidism often leads to symptoms such as fatigue, weakness, and muscle discomfort, which can significantly impact the client's ability to perform daily activities. Addressing activity intolerance is crucial to prevent exacerbation of symptoms and promote the client's overall well-being. Choices A, B, and C are important nursing diagnoses as well, but in the context of hyperthyroidism, addressing activity intolerance takes precedence over the risk for injury related to exophthalmos, impaired social interaction related to emotional lability, and imbalanced nutrition due to hypermetabolism.
