A nurse notes that a client's serum potassium level is 5.9 mEq/L. The nurse interprets this as an expected finding in the client with:

Diabetic ketoacidosis

Heart failure being treated with furosemide

Addison disease

Cushing disease

Answer and Explanation

The Correct Answer is C

Choice A rationale: Typically associated with potassium depletion rather than elevated levels.

Choice B rationale: Furosemide, a loop diuretic, can cause potassium depletion leading to hypokalemia, but it might also cause transient elevations in potassium levels initially. Choice C rationale: Addison disease can cause hyperkalemia, or high potassium, due to decreased renal excretion of potassium and increased retention of sodium and water.

Choice D rationale: Cushing disease can cause hypokalemia, or low potassium, due to increased renal excretion of potassium and decreased reabsorption of sodium and water.

Correct Answer is ["A","D","F"]

Explanation

Choice A rationale: Altered consciousness is a hallmark feature of delirium, where individuals may experience fluctuations in awareness.

Choice B rationale: Delirium typically has an acute onset rather than symptoms developing over months to years.

Choice C rationale: Delirium often has a fluctuating course, rather than a consistent progressive decline.

Choice D rationale: Delirium can result from various factors including fluid/electrolyte imbalances or infections.

Choice E rationale: While these conditions might contribute to cognitive impairments, they are not typically associated with delirium.

Choice F rationale: Delirium can affect judgment, but it's not a defining feature.

Choice G rationale: While memory impairments can be seen in delirium, they're often accompanied by altered consciousness and fluctuations in awareness.
