Which stage of the HIV lifecycle involves the virus attaching to the host cell membrane?

Binding

Integration

Fusion

Reverse Transcription

Answer and Explanation

The Correct Answer is A

A. Binding is the initial step where the HIV virus attaches to the CD4 receptor on the host cell's surface. This interaction is crucial for the subsequent entry of the virus into the host cell.
B. Integration occurs later in the lifecycle, after the virus has entered the host cell and its RNA is converted to DNA.
C. Fusion refers to the process where the viral envelope fuses with the host cell membrane to allow entry into the cell, which follows the binding stage.
D. Reverse Transcription is the process of converting viral RNA into DNA after the virus has entered the host cell, and is not involved in the attachment phase.

Correct Answer is B

Explanation

A. Metabolic acidosis would be indicated by a low pH and a low HCO3, which is not present in this case since HCO3 is normal.
B. The pH of 7.32 indicates acidemia, and a PaCO2 of 50 mmHg suggests respiratory acidosis as the body is retaining carbon dioxide, contributing to the low pH. The HCO3 is normal, indicating that there is no metabolic compensation occurring.
C. Respiratory alkalosis would show a high pH and low PaCO2, which is not the case here.
D. Metabolic alkalosis would present with a high pH and elevated HCO3, which is also not present in these ABG results.

A. Cardiac tamponade B. Third spacing C. Ruptured aneurysm D. Cardiomyopathy

Correct Answer is A

Explanation

A. Cardiac tamponade is a condition where fluid accumulates in the pericardial space, exerting pressure on the heart and impeding its ability to pump effectively, leading to obstructive shock.
B. Third spacing refers to fluid accumulation in the interstitial spaces but is not a specific diagnosis of obstructive shock.
C. A ruptured aneurysm may lead to hypovolemic shock due to blood loss rather than obstructive shock, which is characterized by physical obstruction to blood flow.
D. Cardiomyopathy is a disease of the heart muscle that affects its ability to pump blood, leading to cardiogenic shock, not obstructive shock.
