Nurse educator presenting on basic first aid for new home health nurses. She evaluates teaching as effective when a new nurse states that a client who has heat stroke will have which of the following?

The correct answer is A: Hypotension. Heat stroke leads to severe dehydration and vasodilation, causing a drop in blood pressure (hypotension). Bradycardia (B), clammy skin (C), and bradypnea (D) are not characteristic of heat stroke. Bradycardia is a slow heart rate, while heat stroke typically causes tachycardia. Clammy skin is more indicative of shock or hypoglycemia, not heat stroke. Bradypnea is slow breathing, but heat stroke usually leads to rapid, shallow breathing. Therefore, hypotension is the most appropriate choice as it aligns with the physiological response to heat stroke.
