The charge nurse of a critical care unit is informed at the beginning of the shift that less than the optimal number of registered nurses (RN) will be working that shift. In planning assignments, which client should receive the most care hours by a RN?

A. The combination of cognitive impairment, physical injury, and restraints poses a high risk for complications such as infection, skin breakdown, and falls. Close monitoring and nursing interventions are critical to ensure safety, comfort, and appropriate care in this patient. B. While this client may need some care for the electrolyte imbalance and nausea, this situation is more stable compared to the elderly client with Alzheimer's. The RN's role here would focus on managing the electrolyte disturbance and providing symptom relief. C. Although this client is postoperative and may need some care, the RN's focus would primarily be on pain management and monitoring for infection or complications. However, the client’s condition is relatively stable compared to the elderly client with multiple risks. D. This client is also stable and may require some ongoing monitoring for respiratory issues. However, the level of care needed is less intensive compared to a client with cognitive issues, restraints, and a recent fracture.
