The client has taken an overdose of an opioid. The nurse knows the client must be carefully observed for which effect on respirations?

The correct answer is C: Bradypnea. When a client overdoses on an opioid, it can lead to respiratory depression, resulting in slow and shallow breathing (bradypnea). This is a serious concern as it can progress to respiratory arrest. Hyperventilation (A) is rapid breathing, not typically seen in opioid overdose. Eupnea (B) is normal breathing pattern. Hyperpnea (D) is increased depth of breathing, not commonly associated with opioid overdose. It is crucial to monitor for bradypnea to intervene promptly and prevent respiratory complications.
