Question 1 of 5
Which stage of the HIV lifecycle involves the virus attaching to the host cell membrane?
Correct Answer: A
Rationale: Binding is when HIV attaches to the CD4 receptor. Integration, fusion, and reverse transcription occur later in the lifecycle.
Question 2 of 5
A nurse is assessing a client for a suspected anaphylactic reaction following a CT scan with contrast media. For which of the following client findings should the nurse intervene first?
Correct Answer: A
Rationale: Stridor indicates airway obstruction, a life-threatening emergency requiring immediate intervention. Hypotension, urticaria, and vomiting are addressed after securing the airway.
Question 3 of 5
In which stage of the HIV lifecycle does the enzyme integrase play a crucial role, and what is its function in that stage?
Correct Answer: B
Rationale: Integrase inserts viral DNA into the host genome during integration. Other stages involve different enzymes or processes.
Question 4 of 5
A 70-year-old male receiving high-dose IV furosemide for heart failure complains of ringing in his ears and dizziness. His current labs show normal potassium and sodium levels. What is the nurse's most appropriate intervention?
Correct Answer: D
Rationale: Ringing in ears and dizziness suggest furosemide ototoxicity. Stopping the infusion and notifying the provider is critical. Other actions risk worsening the condition.
