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 C

Explanation

Choice A rationale: Conus medullaris syndrome involves injury or compression to the end portion of the spinal cord and can present with various symptoms but not necessarily lack of normal sympathetic outflow leading to shock.

Choice B rationale: Concussion is a mild traumatic brain injury, and the symptoms described align more with spinal cord injury leading to neurogenic shock.

Choice C rationale: Neurogenic shock occurs due to the loss of sympathetic tone and is characterized by bradycardia, low blood pressure, and vasodilation following spinal cord injury at or above the level of the sixth thoracic vertebra.

Choice D rationale: Diffuse axonal injury typically presents with more widespread brain injury-related symptoms and is not associated with the specific spinal cord-related symptoms described.

A. pulmonary embolism B. myocardial infarction C. fat embolism syndrome D. compartment syndrome

Correct Answer is C

Explanation

Choice A rationale: Pulmonary embolism would cause chest pain, dyspnea, and hemoptysis, but not petechiae or neurological changes.

Choice B rationale: While chest pain might be associated with myocardial infarction, the combination of symptoms aligns more with a pulmonary embolism.

Choice C rationale: Fat embolism syndrome occurs when fat globules from the bone marrow enter the bloodstream and travel to the lungs, brain, or other organs. This can

cause respiratory distress, neurological impairment, petechiae (reddish-purple spots on the skin), and cardiac dysfunction.

Choice D rationale: Compartment syndrome doesn't typically manifest with respiratory symptoms or reddish-purple spots.
