A nurse is caring for a client who has human immunodeficiency virus (HIV). Which of the following laboratory values would be most concerning to the nurse?
Positive Western blot test
CD4-T-cell count 505 cells/mm³ (nl. 500-1500 cells/mm³)
Platelets 115,000/mm³ (nl. 140,000-400,000/mm³)
White blood cell (WBC) count 800/mm³ (nl. 5000-10,000/mm³)
The Correct Answer is D
A. A positive Western blot test confirms the diagnosis of HIV, but it is not concerning once the diagnosis has been established.
B. A CD4-T-cell count of 505 cells/mm³ is low but not critically low. While it does indicate immunosuppression, it is not the most concerning value presented.
C. A platelet count of 115,000/mm³ is lower than normal and may indicate a risk for bleeding, but it is not as concerning as a critically low white blood cell count.
D. A WBC count of 800/mm³ is severely low and indicates a high risk for infection, which is particularly concerning in a client with HIV, as it suggests significant immunosuppression and vulnerability to opportunistic infections.

Correct Answer is ["1.8"]
Explanation
Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of nitroglycerin (units/mL)
First, calculate the concentration of nitroglycerin in the IV bag:
- 100 mg / 250 mL = 0.4 mg/mL
Next, convert the desired dose from mcg/min to mg/hr:
- 12 mcg/min 60 min/hr = 720 mcg/hr = 0.72 mg/hr
Finally, plug the values into the formula:
- Infusion rate = 0.72 mg/hr / 0.4 mg/mL = 1.8 mL/hr
Correct Answer is ["B","C","D","E"]
