Final answer:
A nurse should question a healthcare provider's order of IV morphine for clients with conditions like respiratory depression, head injuries, or decreased consciousness, due to the risk of respiratory failure.
Step-by-step explanation:
The nurse should question the administration of IV morphine for a client who is displaying symptoms or has a history that suggests respiratory depression, decreased respiratory reserve (such as in chronic obstructive pulmonary disease or asthma), head injury, decreased level of consciousness, or any other contraindication to morphine use. Due to morphine's respiratory depressant effects, it's crucial to ensure that a patient's respiratory status is stable enough to handle the drug. The nurse, surgeon, and anesthesia professional play key roles in reviewing the recovery and care plan for a patient, which includes proper medication orders.
