A home health nurse is caring for an older adult client who reports. "I keep coughing when I try to swallow my food, but not at other times." Which of the following actions should the nurse take?

Rationale:

A. Bradypnea: Respiratory depression is the most serious and potentially life-threatening adverse effect of morphine, especially after IV administration when onset is rapid. Bradypnea indicates a compromised airway and inadequate ventilation, making it the nurse’s priority for immediate assessment and intervention to prevent hypoxia and respiratory arrest.

B. Sedation: Sedation is a common effect of morphine and requires monitoring, but it is less immediately dangerous than respiratory depression. The nurse should assess the depth of sedation and level of consciousness while ensuring airway safety.

C. Constipation: Constipation is a common long-term side effect of opioids, but it is not an immediate threat to life. Preventive measures can be planned, but it does not take priority over acute respiratory compromise.

D. Euphoria: Euphoria may occur with opioid administration and is generally not harmful in the short term. While the nurse should monitor for behavioral changes or signs of misuse, it does not pose an immediate risk compared with respiratory depression.

Rationale:

A. Magnesium sulfate: Magnesium sulfate does not have significant interactions with warfarin and is not contraindicated. It can be safely administered with appropriate monitoring, making it safe in this context.

B. Ibuprofen: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of bleeding when taken with warfarin. It inhibits platelet function and can potentiate anticoagulation, making it contraindicated.

C. Cetirizine: Cetirizine is an antihistamine that does not significantly affect coagulation or interact with warfarin. It can be safely used with warfarin under normal circumstances.

D. Gingko biloba: Gingko biloba can increase the risk of bleeding by inhibiting platelet aggregation. Clients on warfarin should avoid herbal supplements like gingko that can potentiate anticoagulation effects.

E. Aspirin: Aspirin has antiplatelet effects and can significantly increase the risk of bleeding when combined with warfarin. Concurrent use is generally contraindicated unless specifically approved and closely monitored by the provider.
