In which stage of the HIV lifecycle does the enzyme integrase play a crucial role, and what is its function in that stage?

Assembly. Integrase packages the viral RNA into new virions.

Integration: Integrase inserts viral DNA into the host's genome.

Entry: Integrase helps the virus fuse with the host cell membrane.

Reverse Transcription: Integrase copies viral RNA into DNA.

Answer and Explanation

The Correct Answer is B

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 A

Explanation

A. Respiratory acidosis is characterized by a low pH (7.32) and an elevated PaCO2 (48 mm Hg), indicating that the body is unable to eliminate CO2 effectively, leading to acid retention. The HCO3 level is within normal limits, suggesting that there is not a metabolic compensation occurring yet.
B. Metabolic alkalosis would present with a high pH and elevated bicarbonate levels, which is not the case here.
C. Respiratory alkalosis typically shows a high pH and low PaCO2, indicating hyperventilation, which does not align with the current findings.
D. Metabolic acidosis would show a low pH with a low HCO3, which is not supported by the HCO3 level of 23 mEq/L in this case.

A. Cortisol B. Bicarbonate C. Albumin D. Potassium

Correct Answer is D

Explanation

A. Cortisol levels are not directly affected by furosemide; monitoring for adrenal function is not a priority.
B. Bicarbonate levels are not specifically monitored for clients on furosemide; this medication's main effect does not relate directly to bicarbonate balance.
C. Albumin levels are not primarily affected by furosemide; although low albumin can affect fluid status, it is not the critical monitoring focus.
D. Potassium levels should be monitored because furosemide is a loop diuretic that can lead to hypokalemia, which is a common and significant side effect due to increased renal excretion of potassium.
