Final answer:
The nursing action that requires the completion of an incident report is giving the medication when the client's apical pulse is 58/min.
Step-by-step explanation:
The nursing action that requires the completion of an incident report is C. Giving the medication when the client's apical pulse is 58/min.
Administering medications and monitoring the client's vital signs are key responsibilities of nurses. The normal range for the apical pulse rate in adults is typically 60-100 beats per minute. A pulse rate of 58 beats per minute indicates bradycardia (a slow heart rate), which can be a cause for concern and may necessitate further assessment or intervention. Therefore, administering the medication in this situation requires documenting the incident and notifying the appropriate healthcare provider.
