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
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
Explanation
Choice A rationale: Considering the mechanism of injury, pain severity, tenderness, swelling, and ecchymosis, there is a high suspicion of a fracture. Immobilization is essential to prevent further injury and reduce pain.
Choice B rationale: Contracture is less likely in this acute injury scenario. Acetaminophen might manage pain, but it doesn't address the risk factor.
Choice C rationale: A sprain is less likely given the severity of pain and the mechanism of injury. Raising the leg doesn't address the risk of a suspected fracture.
Choice D rationale: Dislocation doesn't align with the reported symptoms. Applying heat could potentially worsen inflammation.
Correct Answer is B
Explanation
Choice A rationale: While joint deformities are concerning in RA, the immediate attention would be required for an acute, red, hot, swollen joint which could indicate an active inflammatory process.
Choice B rationale: Redness, heat, and swelling in a joint are signs of an acute flare in rheumatoid arthritis and might require urgent intervention to manage the inflammation.
Choice C rationale: Puffy-looking areas behind the knee might indicate joint involvement but might not require immediate attention as much as an acutely inflamed joint.
Choice D rationale: Jaw pain while eating can be a symptom of TMJ involvement in RA, but an acutely inflamed joint would generally take precedence.
