Final answer:
The client is at risk for developing a potassium deficit due to sustained tissue damage, nasogastric suctioning, a history of Addison's disease, and taking a potassium-sparing diuretic.
Step-by-step explanation:
The client is at risk for developing a potassium deficit due to the following reasons:
- Sustained tissue damage can result in potassium loss as potassium is needed for proper cellular function.
- Nasogastric suctioning can lead to potassium depletion as it removes stomach contents, which may contain potassium.
- Having Addison's disease can cause a decrease in potassium levels due to impaired kidney function.
- Taking a potassium-sparing diuretic can prevent the excretion of potassium by the kidneys, leading to potassium accumulation and deficits in the body.
