Question 1 of 5
A nurse is caring for a client who has a peanut allergy. The client ate peanut butter and is now experiencing anaphylaxis. Which of the following physiological responses should the nurse expect to occur?
Correct Answer: B
Rationale: The correct answer is B: Blood vessels become more permeable. During anaphylaxis, the body releases histamine causing blood vessels to dilate and become more permeable. This leads to fluid leakage from blood vessels, causing swelling and a drop in blood pressure.
Choice A is incorrect as anaphylaxis typically causes a drop in blood pressure due to vasodilation.
Choice C is incorrect because blood vessels do not constrict during anaphylaxis.
Choice D is incorrect as white blood cells are not destroyed during anaphylaxis.
