Answer to Question 1

B
Feedback:
Effector or cytotoxic T cells either destroy a foreign cell or make it available for aggressive destruction. Cells that identify specific proteins or antigens are B cells. Cells that respond to chemical indicators to stimulate other cells are helper T cells. Cells that suppress or slow the reaction are suppressor T cells.

Answer to Question 2

B
Feedback:
The nurse will check the patient's digoxin level and electrolytes. Assessing vital signs is important because the risk of cardiac arrhythmias could increase due to the patient's receiving furosemide, which is a potassium-losing diuretic. The adverse effects most frequently seen with the cardiac glycosides include headache, weakness, drowsiness, and vision changes (a yellow halo around objects is often reported). Gastrointestinal (GI) upset and anorexia also commonly occur. Only after checking lab values and assessing vital signs might the nurse call the physician. Acetaminophen and Maalox would not be indicated. Having her lie down and restricting her diet to clear liquids would be appropriate but not the first actions.
