Question 3 of 5
Which of the following is NOT a common cause of hypokalemia (low potassium levels)?
Correct Answer: D
Rationale: Potassium is an essential electrolyte vital for nerve and muscle function. Hypokalemia, or low potassium, can be caused by factors that deplete the body's potassium levels. Diuretics can increase potassium excretion, excessive vomiting leads to electrolyte loss, and kidney disease impairs potassium regulation. Constipation, however, does not directly contribute to potassium depletion.

Correct Answer: C
Rationale: When considering hypertonic solutions, extra assessment is needed for the condition of the heart. Hypertonic solutions have a higher concentration of solutes compared to the body's cells, which can cause fluid to be drawn out of the cells and into the bloodstream. This can lead to an increase in blood volume and put additional strain on the heart. Therefore, it is important to assess the condition of the heart before administering hypertonic solutions to ensure it can handle the increased workload.

Correct Answer: B
Rationale: The most important education to be done in teaching about hypokalemia is bowel management care. Hypokalemia is a condition characterized by low levels of potassium in the blood, which can lead to gastrointestinal symptoms, including constipation. Educating patients about proper bowel management, such as increasing fiber intake, staying hydrated, and regular exercise, is crucial in managing hypokalemia effectively.
