Correct Answer: A

Rationale: The correct answer is A. Levothyroxine should be taken in the morning on an empty stomach to prevent insomnia and ensure proper absorption of the medication. Choice B is incorrect because taking levothyroxine at night may interfere with sleep and absorption. Choice C is incorrect as stopping the medication without consulting the healthcare provider can lead to negative health outcomes. Choice D is incorrect because levothyroxine is a daily medication that should be taken consistently, not just when symptoms are present.

Correct Answer: A

Rationale: To calculate the mL to be administered, convert 250 mg to grams (0.25 g). Then, set up a proportion: (0.25 g / 3 g) x 5 mL = 0.4167 mL, which rounds to 0.4 mL. Therefore, the healthcare professional would administer 0.4 mL per dose. Choice B (0.3 mL) is incorrect because it does not reflect the accurate calculation. Choice C (0.5 mL) is incorrect as it does not consider the correct conversion and calculation. Choice D (0.6 mL) is incorrect as it provides a value higher than the accurate calculation.

Correct Answer: D

Rationale: Clients with renal failure are at risk for electrolyte imbalances and hypertension. Monitoring electrolyte levels is crucial because renal failure can lead to imbalances in sodium, potassium, and other electrolytes. Blood pressure monitoring is essential as hypertension is a common complication of renal failure. Therefore, both electrolyte levels and blood pressure should be closely monitored to detect and manage any abnormalities. Fluid intake, while important, is not specific to renal failure monitoring and is not the priority in this case.

Correct Answer: A

Rationale: The correct answer is to limit intake of processed foods. Processed foods are often high in sodium, which goes against the goal of a low-sodium diet. Fresh fruits and vegetables are recommended for a low-sodium diet due to their natural low sodium content. The use of accessory muscles and monitoring for allergic reactions are not related to dietary modifications for a low-sodium diet.

Correct Answer: C

Rationale: The correct answer is C, 'Living will.' A living will is a legal document that outlines an individual's preferences for life-sustaining medical treatment if they become unable to make decisions. Choice A, 'Do Not Resuscitate,' specifically refers to a directive that instructs healthcare providers not to perform CPR. Choice B, 'Informed consent,' pertains to a patient's right to be informed about and consent to medical treatment. Choice D, 'Durable power of attorney for health care,' involves appointing someone to make healthcare decisions on behalf of an individual when they are unable to do so.
