Answer and Explanation

The Correct Answer is A,B,C,D,E,F

1. Assessing the client's airway is the priority to determine if there is any obstruction or compromise due to swelling.

2. Calling the emergency response team ensures that additional medical help is on the way if the situation worsens.

3. Applying high-flow oxygen is critical to address potential hypoxia from airway swelling.

4. Initiating IV access is necessary for administering medications.

5. Administering IV epinephrine is essential to counteract severe allergic reactions, such as angioedema.

6. Administering IV antihistamines can help alleviate symptoms but is secondary to the immediate interventions for airway management and epinephrine administration.

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.

A. Fusion Inhibitors B. Integrase Inhibitors C. Nucleoside Reverse Transcriptase Inhibitors (NRTIs) D. Protease Inhibitors

Correct Answer is C

Explanation

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.
