Question 1 of 5
A 65-year-old female presents with confusion, headache, and muscle weakness. Her sodium level is 120 mEq/L. Which of the following interventions is most appropriate based on her condition?
Correct Answer: A
Rationale: Hypertonic saline corrects severe hyponatremia (120 mEq/L), and water restriction prevents further sodium dilution. Other options may worsen the condition.
Question 2 of 5
Which stage of the HIV lifecycle involves the virus attaching to the host cell membrane?

A nurse is caring for a client who is in the compensatory stage of shock. Which of the following findings should the nurse expect?

Question 4 of 5
A nurse is monitoring a client who received epinephrine for angioedema after a first dose of losartan. Which of the following data indicates a therapeutic response to the epinephrine?
