A nurse is caring for a client who has a fractured leg and rates their pain as 7 on a scale of 0 to 10. Which of the following medications should the nurse expect to administer?

A. Gather supplies for a client's dressing change after removing the old dressing: This approach is inefficient and can lead to delays in care. Effective time management involves preparing all necessary supplies beforehand to minimize interruptions and ensure a smooth workflow.

B. Complete activities for one client before moving to the next client: Organizing care around each client and completing all required interventions in one visit promotes efficiency, reduces the risk of missed tasks, and allows better prioritization of nursing responsibilities.

C. Document assessment findings and interventions after providing care for a group of clients: Delaying documentation increases the risk of forgetting important details and can compromise patient safety. Timely documentation is essential for accurate communication and continuity of care.

D. Delay cleaning personal work area until the end of the shift: Maintaining an organized and clean work environment throughout the shift prevents clutter, reduces errors, and supports efficient care delivery. Postponing cleaning can hinder workflow and time management.

A. Atrial fibrillation: Atrial fibrillation is characterized by absent P waves and an irregularly irregular ventricular rhythm. A constant P-R interval is not observed in this dysrhythmia.

B. Complete heart block: Complete heart block (third-degree AV block) shows no relationship between P waves and QRS complexes, with atrial and ventricular rhythms independent of each other. A constant prolonged P-R interval is not present.

C. First-degree atrioventricular block: First-degree AV block is defined by a consistently prolonged P-R interval (>0.20 seconds) with all atrial impulses conducted to the ventricles. A P-R interval of 0.35 seconds indicates delayed AV conduction consistent with first-degree AV block.

D. Premature atrial complexes: Premature atrial complexes present as early P waves with abnormal morphology, often followed by a normal QRS. The P-R interval may be normal or slightly altered, but a consistently prolonged P-R interval is not characteristic.
