A nurse is providing teaching about immunizations to a client who is pregnant. Which of the following statements should the nurse include in the teaching?

Choice A rationale:

Decreased temperature is not a typical sign of naloxone reversing the effects of an opioid overdose. Opioid overdose commonly leads to respiratory depression and hypoxia, but it does not significantly affect body temperature. Naloxone works by binding to the same receptors in the brain that opioids bind to, thereby reversing the effects of the overdose. The primary signs of successful reversal include improved respiratory rate and increased alertness, not changes in body temperature.

Choice B rationale:

Polyuria (excessive urination) is not a specific indicator of naloxone effectiveness. Opioid overdose and naloxone administration primarily affect the central nervous system and respiratory function, not urinary output. Naloxone's effects are more evident in the client's level of consciousness, respiratory rate, and overall responsiveness.

Choice C rationale:

Bradycardia (slow heart rate) is not an expected indicator of naloxone effectiveness. Opioid overdose typically causes respiratory depression, leading to a decreased respiratory rate and oxygen saturation. Naloxone works by reversing this respiratory depression and improving ventilation. Consequently, increased respiratory rate, not heart rate, is a more relevant indicator of naloxone's effectiveness in reversing opioid overdose.

Choice D rationale:

This is the correct answer. Increased respiratory rate is a key indicator that naloxone is reversing the effects of an opioid overdose. Opioid overdose depresses the respiratory system, leading to slow and shallow breathing. Naloxone, as an opioid receptor antagonist, rapidly reverses this effect, leading to a noticeable increase in the client's respiratory rate. Monitoring for improved breathing and increased oxygen saturation is crucial to assessing the effectiveness of naloxone in treating opioid overdose.

A. Administer oxytocin. (This is unanticipated as the client is experiencing contractions, and oxytocin might not be needed at this point.)
D. Limit fluid intake to 3,000 mL/day. (Fluid restriction might not be necessary based on the provided notes.)
F. Place client in supine position. (The supine position is generally avoided during pregnancy due to potential compression of the vena cava.)
