Correct Answer: C

Rationale: The healthcare professional should verify the client's vaccination history to ensure they are due for the flu vaccine. Verifying the client's age (choice A) is important for other vaccines but not specifically for the flu vaccine. While allergy to eggs (choice B) is relevant as the flu vaccine is traditionally produced in eggs, it is not the top priority for verification. The client's weight (choice D) is not directly related to the administration of the flu vaccine.

Correct Answer: A

Rationale: In heart failure, the accumulation of fluid can lead to peripheral edema, which is swelling in the extremities. This is a common sign that healthcare professionals should monitor for. While tachycardia (increased heart rate), bradycardia (decreased heart rate), and hypotension (low blood pressure) can also occur in heart failure, they are not the primary signs typically associated with this condition. Therefore, peripheral edema is the most relevant sign to monitor in this case.

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: C

Rationale: The correct intervention the nurse should include in the teaching is to pad the side rails of the bed. By padding the side rails, the nurse can help prevent injury if the patient experiences a seizure. Administering antiseizure medications promptly (Choice A) is typically the responsibility of a healthcare provider or according to a prescribed schedule. Using oral airway devices during seizures (Choice B) can pose risks and should be managed by healthcare professionals. Applying restraints during a seizure (Choice D) is not recommended as it can lead to further injury and complications.

Correct Answer: D

Rationale: Monitoring blood pressure, weight, and heart rhythm is crucial in clients with a history of heart disease as these parameters can indicate changes in the cardiovascular status. Changes in blood pressure can signify heart strain, weight fluctuations can be related to fluid retention or heart failure, and irregular heart rhythm can indicate arrhythmias or other cardiac issues. Monitoring all these parameters comprehensively allows for early detection of potential complications and timely intervention. Therefore, selecting 'All of the above' is the correct choice as it encompasses all the essential parameters for monitoring in clients with heart disease. Choices A, B, and C are incorrect as monitoring only one or two of these parameters may lead to missing important changes in the client's condition.
