Answer to Question 1

B
Normal blood levels of potassium range between 3.5 and 5.0 mEq/L. The value listed here, 2.6 mEq/L, is low (hypokalemia) and can weaken the skeletal muscles of respiration. Most likely, the diuretic therapy caused the kidneys to excrete too much potassium. Although the blood urea nitrogen level also is lower than normal, it does not pose an immediate health threat.

Answer to Question 2

C
Among the most common side effects of ethosuximide are GI symptoms such as nausea, vomit-ing, and indigestion. The nurse should give this drug with food or a snack to minimize or prevent these symptoms.
