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 B
Explanation
A. In the assembly stage, other proteins and enzymes are involved in the packaging of viral components into new virions, not integrase.
B. During the integration stage, integrase is essential as it inserts the newly formed viral DNA into the host's genome, enabling the virus to utilize the host's cellular machinery for replication.
C. Integrase does not participate in the entry stage; this stage is facilitated by other proteins that aid in the fusion of the virus with the host cell membrane.
D. Integrase is not involved in reverse transcription; that process is facilitated by the enzyme reverse transcriptase, which converts viral RNA into DNA.
Correct Answer is B
Explanation
A. Hepatitis is a concern for individuals with HIV, but it is not specifically indicated by a low CD4-T-cell count.
B. A CD4-T-cell count of 150/mm³ indicates severe immunosuppression, making the client highly susceptible to opportunistic infections like tuberculosis, which is common in individuals with HIV.
C. While gonorrhea is a risk for sexually active individuals, it is not specifically related to the low CD4-T-cell count.
D. Chlamydia is also a sexually transmitted infection, but similar to gonorrhea, it is not directly linked to the immunocompromised state indicated by the CD4-T-cell count.
