Answer to Question 1

C
Quinidine can cause plasma levels of digoxin to rise; concurrent use of quinidine and digoxin is contraindicated. There is no indication for adding spironolactone unless this patient's potassium level is elevated. The dose of digoxin ordered is a low dose. Potassium supplements are con-traindicated with digoxin.

Answer to Question 2

D
The nurse understands that this patient may be vulnerable to opportunistic infections, especially if there were an indication of the HIV conversion to acquired immunodeficiency syndrome (AIDS). A very low helper T lymphocyte count would most concern the nurse, because the helper T cells are essential to the immune system, and people with AIDS have a low or deficient count. A high level of macrophages could indicate an inflammatory response. A low RBC count may indicate anemia. A low neutrophil count can be caused by multiple conditions, but a high count most likely indicates an infection.
