Final answer:
The highest priority nursing problem for an immobile client with fecal incontinence and diarrhea is the risk of skin breakdown and dehydration. Close monitoring and care are necessary to prevent further complications.
Step-by-step explanation:
The identification of nursing problems for a client who is immobile and has been experiencing fecal incontinence and diarrhea requires prioritization based on the severity and impact on the client's health status. In the context of an immobile client, the primary caregiver's capacity to manage these conditions is crucial. The highest priority nursing problem in this situation would likely be the risk of skin breakdown due to fecal incontinence and the potential for severe dehydration caused by prolonged diarrhea. Fecal incontinence can lead to moisture-associated skin damage, while diarrhea increases the risk of dehydration and electrolyte imbalance. Both conditions demand prompt and appropriate nursing interventions to prevent complications.
