In which scenario would a nurse instruct a nursing assistant to use a urinal in bed instead of a standing position?

Using a urinal while in bed is especially appropriate for patients who have significantly limited mobility, such as those with paralysis. In the scenario involving the patient with complete left-sided paralysis due to a stroke, the patient's ability to stand or move independently is severely impaired. This creates a risk of falls and injury if the patient attempts to use the urinal while standing. By instructing the nursing assistant to provide the urinal while the patient is in bed, the nurse ensures the patient's safety and comfort by allowing them to use the device without the need to move out of a stable position. This approach is crucial in the care of patients with mobility challenges, emphasizing the importance of adapting nursing care to meet the specific needs of each patient.

The other scenarios involve patients who either have better mobility or require different considerations, such as their overall condition or treatment protocol, making the usage of a urinal while standing more feasible or necessary.
