Correct Answer: D

Rationale: The correct answer is to take levothyroxine on an empty stomach. This is because levothyroxine should be taken in the morning on an empty stomach to ensure proper absorption. Option A is incorrect because levothyroxine is usually advised to be taken in the morning. Option B is not the priority teaching point as monitoring for hypothyroidism symptoms is ongoing care. Option C is incorrect as levothyroxine should not be taken with calcium supplements as they can interfere with its absorption.

Correct Answer: B

Rationale: The correct answer is B: Peripheral edema. In heart failure, the heart's inability to pump effectively can lead to fluid backup, causing swelling in the extremities, known as peripheral edema. Monitoring for peripheral edema is crucial as it is a common sign of worsening heart failure. Choices A, C, and D are incorrect because increased energy, elevated heart rate, and improved lung sounds are not typical findings in heart failure. Increased energy is not usually associated with heart failure, an elevated heart rate may occur as a compensatory mechanism but is not a direct sign of heart failure, and improved lung sounds are not expected in heart failure which often presents with crackles or wheezes due to pulmonary congestion.

Correct Answer: A

Rationale: The correct answer is to assess blood pressure first. Losartan is an angiotensin receptor blocker used to lower blood pressure. Assessing the patient's blood pressure before administering losartan is crucial to ensure it is not already too low, which could lead to hypotension. Assessing heart rate (choice B) is important but not the priority when administering losartan. Serum potassium levels (choice C) and liver function (choice D) are also important assessments, but they are not the primary concern before administering losartan.

Correct Answer: A

Rationale: The correct answer is to monitor for withdrawal symptoms. This is a priority because individuals with a history of substance abuse are at risk of experiencing withdrawal symptoms when the substance is no longer used. Monitoring for withdrawal symptoms is crucial to ensure the client's safety and to manage any potential complications related to substance withdrawal. Encouraging social activities, scheduling regular follow-ups, and providing educational materials are also important aspects of care, but they are not as critical as monitoring for withdrawal symptoms in this immediate scenario.

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.
