Correct Answer: D

Rationale: Administering an additional dose of naloxone should be the first action taken by the nurse in this scenario. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. If the client's level of consciousness deteriorates after the initial dose, administering another dose can help further reverse the overdose effects and improve the client's condition. Once the additional naloxone dose is given, the nurse can then proceed to assess the client's response and consider other interventions as needed.

Correct Answer: A

Rationale: The correct answer is A: Dizziness. Metoprolol, a beta-blocker, can lead to dizziness as a common side effect due to its mechanism of action in reducing heart rate and blood pressure. This effect can cause a sensation of lightheadedness or unsteadiness, particularly when standing up quickly. While fatigue, orthostatic hypotension, and headache are potential side effects of metoprolol, dizziness is commonly observed and should be closely monitored by the nurse to ensure patient safety.

Correct Answer: C

Rationale: It is crucial for clients to understand that they should not discontinue escitalopram abruptly, even if they start feeling better. Stopping the medication suddenly can lead to withdrawal symptoms or a relapse of depression. It is essential to complete the full course of treatment as prescribed by the healthcare provider to ensure the best outcomes and prevent potential complications.

Correct Answer: B

Rationale: Amlodipine, a calcium channel blocker, commonly causes peripheral edema as an adverse effect. This is due to its vasodilation effects on blood vessels, leading to fluid accumulation in the extremities. Monitoring for peripheral edema is crucial to assess the client's response to amlodipine and ensure timely intervention if needed.

Correct Answer: B

Rationale: The correct answer is B: History of an egg allergy. The influenza vaccine may contain a small amount of egg protein. According to the CDC, individuals with a severe allergy to any component of the vaccine, including egg protein, should not receive the influenza vaccine. Therefore, if the client has a history of an allergy to eggs, the practical nurse should not administer the vaccine and consult with the charge nurse for further guidance, as it is a contraindication. The other conditions listed do not require consultation before administering the influenza vaccine.
