Fusion Inhibitors

Integrase Inhibitors

Nucleoside Reverse Transcriptase Inhibitors (NRTIs)

Protease Inhibitors

Answer and Explanation

The Correct Answer is C

A. Fusion Inhibitors work by preventing the virus from entering the host's cells but do not inhibit RNA from forming DNA.
B. Integrase Inhibitors block the integration of viral DNA into the host's DNA but do not directly inhibit the reverse transcription process.
C. Nucleoside Reverse Transcriptase Inhibitors (NRTIs) inhibit reverse transcriptase, the enzyme responsible for converting viral RNA into DNA, thus directly targeting this crucial stage of the HIV lifecycle.
D. Protease Inhibitors inhibit the protease enzyme involved in the maturation of the virus but do not affect the reverse transcription process.

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. Stridor B. Hypotension C. Urticaria D. Vomiting

Correct Answer is A

Explanation

A. Stridor is a high-pitched sound indicating upper airway obstruction and is a critical sign of anaphylaxis requiring immediate intervention to secure the airway.
B. Hypotension is a serious condition that occurs during anaphylaxis, but the priority is to address the airway obstruction first.
C. Urticaria (hives) is a common symptom of an allergic reaction but is not life-threatening and can be addressed after more severe symptoms.
D. Vomiting may occur during anaphylaxis but is not the most urgent finding when airway compromise is present.
