A nurse is caring for a client who is receiving morphine.Which of the following assessments should the nurse perform first?

Choice A rationaleAssessing the apical heart rate is important but not the first priority when administering morphine. Respiratory rate takes precedence due to the risk of respiratory depression, a common adverse effect of opioids.Choice B rationaleMonitoring blood pressure is essential, but the first priority is to assess respiratory rate to promptly identify and address any respiratory depression, which is a critical side effect of morphine administration.Choice C rationaleRespiratory rate must be assessed first because morphine can cause respiratory depression. Early detection of decreased respiratory rate ensures timely intervention and prevention of severe complications related to opioid use.Choice D rationaleLevel of consciousness should be monitored, as morphine can cause sedation. However, the initial priority is to assess respiratory rate to detect any immediate life-threatening respiratory depression caused by the opioid. .
