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?
Blood pressure increases.
Blood vessels become more permeable.
Blood vessels constrict.
White blood cells are destroyed.
The Correct Answer is B
A. Blood pressure does not increase during anaphylaxis; instead, it typically decreases due to vasodilation and fluid leakage.
B. During anaphylaxis, blood vessels become more permeable, leading to the release of fluids into the tissues, which causes swelling and contributes to hypotension.
C. Blood vessels do not constrict during anaphylaxis; rather, they dilate as a part of the allergic response, resulting in decreased blood pressure.
D. While there is an immune response during anaphylaxis, white blood cells are not destroyed; rather, they are activated to respond to the allergen, leading to inflammation and other systemic effects.

Correct Answer is C
Explanation
A. Anuria, or the absence of urine output, indicates significant renal impairment and is a later sign of shock.
B. Hypotension is a classic sign of shock but occurs after compensatory mechanisms have failed.
C. An increased respiratory rate is often one of the earliest indicators of shock, as the body attempts to compensate for reduced oxygenation and tissue perfusion by increasing respiratory effort.
D. A decreased level of consciousness can occur with prolonged shock but typically presents after other compensatory mechanisms have been overwhelmed.

B. Fungal and bacterial infections are also associated with advanced HIV/AIDS due to immunosuppression and not seen in the initial phase of infection.
C. Flu-like symptoms and night sweats are common initial symptoms of HIV infection, often occurring 2-4 weeks after exposure during the acute retroviral syndrome phase.
D. Kaposi's sarcoma is a cancer associated with advanced HIV/AIDS and does not manifest during the initial symptoms of infection.
