Correct Answer: C

Rationale: The correct answer is C: 'Numbness and tingling of the fingers.' Post-thyroidectomy, hypocalcemia is a concern due to potential damage to the parathyroid glands that regulate calcium levels. Numbness and tingling of the fingers are classic signs of hypocalcemia. Constipation (Choice A) is not typically associated with hypocalcemia. Frequent urination (Choice B) is more indicative of conditions like diabetes or a urinary tract infection. Increased thirst (Choice D) is commonly seen in conditions such as diabetes insipidus or uncontrolled diabetes mellitus, not specifically related to hypocalcemia.

Correct Answer: C

Rationale: Encouraging the client to take frequent rest periods is an appropriate intervention for managing mania in a client with bipolar disorder. During a manic episode, individuals often have increased energy levels, decreased need for sleep, and may engage in high-risk behaviors. Encouraging regular rest periods can help reduce stimulation and promote relaxation, which may assist in stabilizing mood. Choices A and B are not as effective in managing manic symptoms, as they do not directly address the client's need for rest and relaxation. Choice D is inappropriate because placing the client in seclusion can increase feelings of anxiety and agitation, worsening the manic episode.

Correct Answer: C

Rationale: The correct action for the nurse to take is to limit IV exposure to light. Nitroprusside is light-sensitive, and exposure to light can lead to its degradation, potentially reducing its efficacy in treating severe hypertension. Keeping calcium gluconate at the bedside (Choice A) is not directly related to managing nitroprusside infusion. While monitoring blood pressure every 2 hours (Choice B) is important in managing hypertension, it is not the immediate action required to ensure medication efficacy. Attaching an inline filter to the IV tubing (Choice D) may help filter particles but does not address the critical concern of light sensitivity associated with nitroprusside administration.

Correct Answer: C

Rationale: The correct answer is C. Drinking at least 2 liters of water daily is crucial for clients taking lithium to prevent dehydration and lithium toxicity. Lithium is a salt, so it's important for clients to maintain adequate hydration. Option A is incorrect because lithium does not interact with tyramine-containing foods. Option B is incorrect because increasing salt intake is not necessary and can actually exacerbate lithium toxicity. Option D is incorrect because avoiding caffeinated beverages is not a priority teaching point for clients taking lithium.

Correct Answer: D

Rationale: Measuring the client's intake and output every 2 hours is essential when caring for a client receiving a continuous IV infusion of milrinone. Milrinone is a medication that affects fluid balance, and monitoring intake and output helps assess the client's response to the medication. Continuous monitoring of blood pressure may not be necessary unless there is a specific indication. While weighing the client daily is important for overall assessment, measuring intake and output more frequently provides more real-time data for fluid balance evaluation. Monitoring the infusion site is crucial for detecting infiltration but is not directly related to managing fluid balance in this situation.
