A nurse is preparing a client's body for a postmortem family viewing. Which of the following actions should the nurse take?

A. Difficulty swallowing: Difficulty swallowing is more commonly associated with cranial nerve involvement, neuromuscular disorders, or medication side effects rather than pain perception. It does not reliably reflect inadequate pain control following a spinal epidural. Difficulty swallowing would prompt evaluation of airway or neurologic status rather than pain relief.

B. Urinary retention: Urinary retention is a known effect of spinal or epidural anesthesia due to temporary blockade of sacral nerves. It reflects autonomic nervous system involvement rather than the client’s pain level. Retention can occur even when pain is adequately managed.

C. Restlessness: Restlessness is a common behavioral indicator of unrelieved pain, especially when pain persists despite treatment. Clients may appear unable to relax, frequently change positions, or seem agitated when discomfort is not controlled. This finding suggests the need for reassessment of pain management effectiveness.

D. Constipation: Constipation is associated with opioid use, reduced mobility, or decreased gastrointestinal motility rather than uncontrolled pain. It develops over time and is not an acute indicator of ineffective pain relief. It would prompt bowel management rather than pain reassessment.

A. Nursing care plan: The care plan outlines planned interventions and goals for the client’s care. It is not the appropriate place to document medication errors, as it is intended for ongoing care rather than reporting incidents or deviations from standard practice.

B. Provider's progress notes: While the provider should be notified of the error, documenting it in progress notes alone does not fulfill institutional or legal requirements for reporting medication errors. Progress notes are primarily for client assessment and treatment updates.

C. Incident report: An incident report is the correct location to document a medication error. It provides a formal record for quality improvement, risk management, and legal purposes. Documentation should be factual, timely, and include details of the error and immediate actions taken.

D. Controlled substance inventory record: This record tracks the administration and count of controlled substances. While the codeine component must be accounted for in the inventory, the inventory itself does not replace the need for an incident report to document the error comprehensively.
