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

Explanation

Choice A rationale: The correct answer is 5 units/hour. To calculate the units of insulin per hour, we need to use the following formula: units of insulin per hour = (units of insulin in the bag / volume of the bag) x infusion rate

Plugging in the given values, we get:

units of insulin per hour = (50 / 100) x 10 units of insulin per hour = 0.5 x 10

units of insulin per hour = 5

Therefore, the client is receiving 5 units of insulin every hour.

Choice B rationale: This is incorrect because it assumes that the infusion rate is equal to the units of insulin per hour, which is not true.

Choice C rationale: This is incorrect because it multiplies the units of insulin in the bag by the infusion rate, which is too high.

Choice D rationale: This is incorrect because it adds the units of insulin in the bag and the infusion rate, which is also too high.

A. Conus medullaris syndrome B. Concussion C. Neurogenic shock D. Diffuse axonal injury

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.
