A nurse is caring for a client who has a new prescription for mirtazapine. Which of the following medications should the nurse identify as a contraindication to the client's new prescription?

A. “Heart rate”: While it’s important to monitor the heart rate of a client who has received naloxone, it’s not the first assessment that should be made. Opioid toxicity can lead to life-threatening respiratory depression, so the priority is to assess the client’s respiratory status.

B. “Pain level”: Pain level is an important consideration when administering any medication, but it’s not the first assessment to be made following naloxone administration. The priority is to assess the client’s respiratory status, as opioid toxicity can cause life-threatening respiratory depression.

C. “Blood pressure”: Monitoring blood pressure is important in any client receiving medication, but it’s not the first assessment to be made following naloxone administration. The priority is to assess the client’s respiratory status, as opioid toxicity can cause life-threatening respiratory depression.

D. “Breath sounds”: This is the correct answer. The primary risk with opioid toxicity is respiratory depression, which can be life-threatening. Naloxone is administered to reverse this effect. Therefore, the nurse should first assess breath sounds to determine if the client’s respiratory status is improving.

A) Monitor the client's oxygen saturation:
Monitoring the client's oxygen saturation is essential during moderate sedation with diazepam to assess respiratory status and detect any signs of respiratory depression, which can be an adverse reaction to the medication. Decreased oxygen saturation can indicate hypoventilation, a potential complication of sedative medications like diazepam.

B) Check the client's urinary output:
While monitoring urinary output is important for assessing renal function, it is not directly related to adverse reactions to diazepam or moderate sedation.

C) Monitor the client for seizure activity:
Seizure activity is a potential adverse reaction to diazepam, particularly if the client has a history of seizures or epilepsy. However, during moderate sedation, the focus is on assessing respiratory status and sedation depth rather than monitoring for seizure activity.

D) Auscultate the client's bowel sounds:
Auscultating bowel sounds is not directly related to assessing adverse reactions to diazepam or moderate sedation. It is more pertinent in assessing gastrointestinal function, which may be affected by other factors but is not typically a primary concern during moderate sedation
