A nurse is planning care for a client who has terminal cancer and has a prescription for morphine. Which of the following interventions should the nurse include in the plan of care?

A. Itching (pruritus) is a common side effect of morphine due to histamine release, not necessarily an allergy. Stopping pain medication for terminal cancer without a substitute is inappropriate. Instead, the nurse should manage the itch with antihistamines. B. Morphine is a central nervous system (CNS) depressant that significantly suppresses the cough reflex. In a terminal client, this can lead to pooling of secretions in the lungs, increasing the risk of "death rattle" or pneumonia, and collapse of small airways due to shallow breathing and lack of lung expansion. Encouraging the client to cough and deep breathe (when possible) helps clear the airway and improves oxygenation, even if the goal is palliative. C. This is an antidiarrheal. Morphine causes severe constipation, not diarrhea. Giving an antidiarrheal to a patient on morphine could cause a bowel obstruction or paralytic ileus. A stool softener/stimulant laxative is needed instead. D. Morphine causes miosis (pinpoint pupils), which makes it difficult for the eye to adjust to low light. Keeping the room dim during waking hours increases the risk of falls and disorientation.
