A nurse is caring for a client who is receiving heparin therapy. If the client requires a reversal of the effects of heparin, which of the following medications should the nurse expect the provider to prescribe?

A. "Instruct the client's visitors not to operate the PCA pump.” Only the client should press the PCA button to self-administer medication. Allowing visitors or family members to press the button ("PCA by proxy") increases the risk of over-sedation, respiratory depression, and opioid toxicity. The nurse should reinforce to visitors that only the client should control medication delivery based on their own pain level.

B. "Check the client's pain level every 8 hours." Pain assessment should be performed more frequently than every 8 hours when a client is receiving morphine PCA. Pain, sedation level, and respiratory status should be monitored every 1–2 hours initially and then at regular intervals as determined by hospital protocol to ensure effective pain management and prevent complications such as respiratory depression.

C. "Diarrhea is an adverse effect of morphine PCA." Morphine is an opioid analgesic that commonly causes constipation, not diarrhea. Opioids slow gastric motility, which can lead to delayed bowel movements, bloating, and discomfort. Clients on long-term opioid therapy often require stool softeners or laxatives to prevent opioid-induced constipation.

D. "Using morphine PCA increases the client's risk of toxicity." PCA pumps are designed with preset dose limits and lockout intervals to prevent overdose. While there is a risk of opioid toxicity if the system is misused (e.g., PCA by proxy or improper settings), PCA is actually safer than traditional opioid administration methods because it allows for precise dosing and patient-controlled pain management. Proper monitoring helps prevent complications.

A. Anorexia. While gastrointestinal side effects such as nausea and esophageal irritation can occur with alendronate, anorexia is not a common adverse effect. If severe nausea leads to decreased appetite, the client should report this to their provider, but it is not a primary concern compared to more serious side effects.

B. Jaw pain. Jaw pain can indicate osteonecrosis of the jaw (ONJ), a rare but serious adverse effect associated with long-term bisphosphonate use. This condition involves poor bone healing, especially after dental procedures, and can lead to bone deterioration. Clients taking alendronate should report any persistent jaw pain and undergo regular dental exams to monitor bone health.

C. Insomnia. Alendronate does not typically cause insomnia. While some medications, such as corticosteroids and stimulants, are linked to sleep disturbances, alendronate does not affect the central nervous system in a way that would disrupt sleep patterns.

D. Bruising. Alendronate does not interfere with platelet function or coagulation, making bruising an unlikely adverse effect. Clients who experience unexplained bruising should be evaluated for other underlying causes, such as blood disorders or medication interactions.
