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.

Correct Answer: B

Rationale: IV Ca (intravenous calcium) is the correct answer for emergency treatment of hypermagnesemia. Hypermagnesemia is a condition characterized by high levels of magnesium in the blood, which can lead to muscle weakness, cardiac arrhythmias, and respiratory depression. IV calcium antagonizes the effects of magnesium on the heart and neuromuscular system, helping to restore normal function.

Correct Answer: D

Rationale: The correct answer is D (70%). The human body is composed of approximately 60-70% water in adults. Water is essential for various physiological functions, such as regulating body temperature, transporting nutrients, and eliminating waste. The body's water content varies based on factors like age, gender, and body composition. Choice A (30%) is too low, as it would be insufficient for the body to function properly. Choice B (50%) is closer but still underestimates the actual water percentage. Choice C (60%) is a common misconception but falls within the lower range of the correct percentage. Therefore, choice D is the most accurate representation of the average adult's total body water content.

Correct Answer: A

Rationale: The correct answer is A: Bradycardia. In hyperkalemia, there is increased potassium levels in the blood, leading to cardiac abnormalities. Bradycardia is not typically associated with hyperkalemia; instead, it may manifest as tachycardia or irregular heart rhythms. Hyperreflexia, muscle weakness, and tall peaked T-waves on ECG are common signs of hyperkalemia due to the effects of elevated potassium levels on nerve conduction and muscle function.

Correct Answer: A

Rationale: Respiratory acidosis is caused by an increase in CO2 levels due to inadequate ventilation (A). Hypoventilation decreases the removal of CO2, leading to its accumulation and respiratory acidosis. Hyperventilation (B) reduces CO2 levels, causing respiratory alkalosis. Diarrhea (C) and excessive vomiting (D) result in metabolic acidosis due to loss of bicarbonate, not respiratory acidosis.
