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: When a client is prescribed risperidone, it is essential to monitor for potential side effects. Weight gain is a common side effect of risperidone, so the nurse should closely monitor the client's weight throughout the treatment. This monitoring helps in early detection of weight changes and allows for timely interventions to prevent further complications.

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: 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.
