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 D

Explanation

A. Furosemide is a diuretic and is not indicated in the acute management of anaphylaxis.
B. Methylprednisolone is a corticosteroid that may be used later to reduce inflammation but is not the first-line treatment in anaphylaxis.
C. Dobutamine is a medication used to treat heart failure and shock but does not address the acute allergic reaction.
D. Epinephrine is the first-line treatment for anaphylactic shock, as it acts quickly to reverse severe allergic reactions by causing vasoconstriction, bronchodilation, and inhibiting further release of mediators from mast cells.

A. Mottled skin B. Heart rate 160/min C. Blood pressure 115/68 mmHg D. Hypokalemia

Correct Answer is C

Explanation

A. Mottled skin is more indicative of the progressive or refractory stages of shock, where perfusion to the skin is severely compromised.
B. A heart rate of 160/min indicates tachycardia, which is common in shock but is not the most characteristic finding of the compensatory stage.
C. During the compensatory stage of shock, the body attempts to maintain blood pressure and perfusion, and a blood pressure of 115/68 mmHg suggests that compensatory mechanisms are still functioning adequately.
D. Hypokalemia is not a typical finding in the compensatory stage; rather, the body may exhibit signs of hyperkalemia due to tissue breakdown and acidosis.
