1. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

Correct answer: B

Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.

2. The drug of choice to decrease uric acid levels is:

Correct answer: B

Rationale: The correct answer is allopurinol (Zyloprim) as it is a xanthine oxidase inhibitor that decreases uric acid formation. Allopurinol is commonly used to manage gout by lowering uric acid levels. Prednisone is a corticosteroid used to decrease inflammation, not to lower uric acid levels. Indomethacin is an analgesic, anti-inflammatory, and antipyretic agent, but it is not the drug of choice for lowering uric acid levels. Hydrochlorothiazide is a thiazide diuretic used to treat hypertension and edema, not to decrease uric acid levels.

3. Which client is at risk for hypomagnesemia?

Correct answer: D

Rationale: The correct answer is the client admitted with alcohol abuse. Alcoholics tend to have poor nutrition due to decreased food intake, which is a common source of magnesium. Additionally, alcohol suppresses the release of ADH, leading to diuresis and magnesium loss. Choice A is incorrect because a history of heart disease does not directly increase the risk of hypomagnesemia. Choice B is incorrect as taking magnesium-based antacids would not put the client at risk for hypomagnesemia; in fact, it would help prevent it. Choice C is also incorrect as a parathyroid disorder is not typically associated with an increased risk of hypomagnesemia.

4. Which reported symptom would indicate a client with Addison's disease has received too much fludrocortisone (Florinef) replacement?

Correct answer: B

Rationale: Fludrocortisone (Florinef) replacement in Addison's disease involves mimicking aldosterone to retain sodium and water. This retention can lead to weight gain due to increased fluid retention. Rapid weight gain, such as 6 pounds in one week, is a concerning sign of excessive fluid retention, indicating a potential overdose of fludrocortisone. Choices A, C, and D are incorrect because oily skin and hair, loss of muscle mass, and increased blood glucose levels are not specific symptoms of excessive fludrocortisone replacement in Addison's disease.

5. A mother brings her 13-month-old child with Down Syndrome to a pediatric clinic reporting muscle weakness and poor movement. The child's reflexes are noted to be diminished. Which action should the nurse take first?

Correct answer: D

Rationale: In a child with Down Syndrome presenting with muscle weakness and diminished reflexes, an atlanto-axial dislocation is a concern. The priority action is to position the child's neck in a neutral c-spine posture to prevent further injury. This should be done before any movement or manipulation. Contacting the physician should follow to ensure appropriate evaluation and management. Initiating an IV is not indicated unless specifically ordered for a medical reason. Ordering an X-ray for a c-spine work-up should not be the first action as it may involve movement that could exacerbate the condition if an injury is present.
