The home health nurse identifies several nursing problems for a client with celiac disease, who had knee replacement surgery 2 weeks ago. The client is experiencing diarrhea and the primary caregiver is the client's spouse. In planning care, which nursing problem has the highest priority?

D. Neuropathy, especially when associated with numbness and tingling in the lower extremities, poses a significant risk for impaired skin integrity. The loss of sensation can lead to decreased awareness of pressure, friction, or trauma to the feet, making the client more susceptible to skin breakdown, ulcers, and injuries.

A. Increasing numbness and tingling in the lower extremities, which primarily suggests neuropathic symptoms rather than impaired mobility.

B. A self-care deficit may arise if the client's neuropathy significantly affects their ability to perform foot care tasks independently. However, self-care deficit becomes a priority concern.

C. Neuropathy can increase the risk of foot injuries due to decreased sensation, which in turn can lead to infections if not promptly addressed. However, while infection is a potential complication, the immediate concern in this scenario is preventing the development of skin breakdown and ulcers.

B. When the oxygen saturation is lower than expected, the nurse's first action should be to verify the accuracy of the reading by ensuring the proper placement and functioning of the pulse oximeter. This involves checking that the pulse oximeter probe is securely attached to the client's finger or other appropriate site and that there are no obstructions or interference affecting the reading.

A. A non-rebreather mask delivers higher concentrations of oxygen compared to a nasal cannula and is typically used when a client requires higher levels of oxygen supplementation. However, switching to a non-rebreather mask may not be appropriate without further assessment.

C. Increasing the oxygen flow rate to 3 L/minute would deliver a higher concentration of oxygen to the client, potentially improving oxygen saturation. However, increasing the oxygen flow should be done cautiously and based on clinical assessment to avoid oxygen toxicity.

D. Removing the nasal cannula would deprive the client of supplemental oxygen, which may not be appropriate if the client's oxygen saturation is already low. Oxygen supplementation is typically provided to improve oxygenation and support vital organ function.
