A nurse is providing teaching to a client who has angina and a new prescription for nitroglycerin tablets. Which of the following instructions should the nurse include in the teaching?
Repeat up to four doses until pain is relieved.
Store unused tablets at room temperature.
Take two tablets at the onset of pain.
Take the medication two hours prior to exercise.
The Correct Answer is B
Choice A rationale
Repeating up to four doses until pain is relieved is incorrect. The correct instruction is to take one tablet at the onset of pain and repeat every 5 minutes if needed, up to a maximum of three tablets in 15 minutes.
Choice B rationale
Storing unused tablets at room temperature is correct. Nitroglycerin tablets should be stored in their original container at room temperature, away from moisture and heat.
Choice C rationale
Taking two tablets at the onset of pain is incorrect. The correct instruction is to take one tablet at the onset of pain and repeat every 5 minutes if needed, up to a maximum of three tablets in 15 minutes.
Choice D rationale
Taking the medication two hours prior to exercise is incorrect. Nitroglycerin should be taken 5 to 10 minutes before an activity that may cause chest pain.

Correct Answer is ["A","E"]
Explanation
Choice A rationale
Muscle weakness is a common symptom of hypokalemia due to decreased potassium levels affecting muscle function.
Choice B rationale
Hyperactive bowel sounds can indicate hypokalemia because potassium is essential for normal gastrointestinal motility. Low potassium levels can lead to increased activity in the intestines, resulting in hyperactive bowel sounds.
Choice C rationale
Tingling of fingers, or paresthesia, can be a symptom of hypokalemia, as low potassium levels may affect nerve conduction. This results in abnormal sensations like tingling or numbness.
Choice D rationale
Peaked T waves are more commonly associated with hyperkalemia rather than hypokalemia. Therefore, this option would not indicate hypokalemia. However, a nurse should be vigilant about monitoring potassium levels as both conditions can lead to significant cardiovascular effects.
Choice E rationale
Fatigue is another symptom of hypokalemia as low potassium levels can impair cellular function and energy production.
