A 45-year-old male presents to the emergency department after experiencing profuse vomiting and diarrhea for 3 days. His blood pressure is 90/60 mmHg, heart rate is 110 beats per minute, and mucous membranes are dry. Which of the following interventions should the nurse prioritize?

Encourage oral intake of water

Administer potassium-sparing diuretic

Restrict fluid intake

Administer IV bolus of normal saline

Answer and Explanation

The Correct Answer is D

A. Encouraging oral intake may not be effective due to the patient's likely need for more rapid rehydration given his low blood pressure and heart rate.
B. A potassium-sparing diuretic is inappropriate in this situation, as the patient is already experiencing fluid loss and requires rehydration, not diuresis.
C. Restricting fluid intake would be contraindicated as the patient is in a state of dehydration and hypotension.
D. Administering an IV bolus of normal saline is the priority intervention to quickly restore fluid volume and improve blood pressure and hydration status.

Correct Answer is C

Explanation

A. Anuria, or the absence of urine output, indicates significant renal impairment and is a later sign of shock.
B. Hypotension is a classic sign of shock but occurs after compensatory mechanisms have failed.
C. An increased respiratory rate is often one of the earliest indicators of shock, as the body attempts to compensate for reduced oxygenation and tissue perfusion by increasing respiratory effort.
D. A decreased level of consciousness can occur with prolonged shock but typically presents after other compensatory mechanisms have been overwhelmed.

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.
