Final answer:
Respiratory depression after an IV bolus of morphine can occur within minutes, with the effects developing over time. Naloxone is used to counteract these effects, particularly in cases of acute overdoses or in newborns affected by maternal narcotic use.
Step-by-step explanation:
The question pertains to the time frame in which respiratory depression can occur after receiving an intravenous (IV) bolus of morphine. Typically, the onset of respiratory depression from morphine administered intravenously can occur within minutes since this route of administration allows for rapid absorption and effect. The full scope of respiratory depression, depending on various factors such as the dose administered and the individual patient's sensitivity, may develop over a finite period and requires close monitoring.
Further safety measures include the administration of opiate antagonists, such as naloxone, which can reverse the effects of morphine, including respiratory depression. Naloxone is particularly important in the context of acute narcotic intoxication or when a newborn is experiencing respiratory depression due to the mother's narcotic use.
Overall, it is crucial for healthcare providers to monitor patients closely after administering morphine, due to the risk of respiratory depression, and have naloxone available for rapid intervention when indicated.
