A nurse is assessing a client who has diarrhea. Which of the following findings is a manifestation of hypokalemia?

Hypertension

Muscle weakness

Hyperactive bowel sounds

Cerebral edema

Answer and Explanation

The Correct Answer is B

Hypokalemia refers to low levels of potassium in the blood. Potassium is an essential electrolyte that plays a crucial role in nerve and muscle cell functioning. When potassium levels are low, it can lead to muscle weakness or even muscle cramps.

Hypertension (high blood pressure) is not commonly associated with hypokalemia. In fact, hypokalemia can sometimes cause low blood pressure (hypotension).

Hyperactive bowel sounds are more commonly associated with conditions such as diarrhea, gastroenteritis, or bowel obstruction. While diarrhea can contribute to electrolyte imbalances, it is not a specific manifestation of hypokalemia.

Cerebral edema refers to swelling in the brain and is not typically associated with hypokalemia. Hypokalemia is more likely to affect muscle and nerve function rather than cerebral edema.

Correct Answer is ["125"]

Explanation

To determine the mL/hr rate for the IV pump, we need to calculate the infusion rate of the

potassium chloride solution. Given:

Potassium chloride concentration: 40 mEq in 500 mL Infusion rate: 10 mEq/hr

We can set up a proportion to find the mL/hr rate:

(40 mEq / 500 mL) = (10 mEq / x mL) Cross-multiplying the equation:

40 mEq * x mL = 500 mL * 10 mEq Simplifying:

40x = 5000

Dividing both sides by 40:

x = 5000 / 40

x ≈ 125

Therefore, the nurse should set the IV pump to deliver approximately 125 mL/hr.
