A nurse is caring for a client who has HIV and a CD4-T-cell count of 150/mm³. Which of the following conditions should the nurse monitor the client for?
Hepatitis
Tuberculosis
Gonorrhea
Chlamydia
The Correct Answer is B
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.

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 C
Explanation
A. Obstructive shock occurs when blood flow is physically obstructed, such as in cases of pulmonary embolism or cardiac tamponade, which is not indicated here as the cause is blood loss.
B. Septic shock is related to infection and systemic inflammatory response, not directly caused by blood loss.
C. Hypovolemic shock is caused by a significant loss of blood volume, leading to decreased blood pressure, which directly relates to the client losing 800 mL of blood during surgery. This condition results in inadequate perfusion and oxygen delivery to tissues.
D. Neurogenic shock results from spinal cord injuries leading to vasodilation and bradycardia, which is not applicable to this scenario.
