Answer to Question 1

3

Rationale: The normal adult ranges of serum electrolyte levels are sodium, 136 to 145 mEq/L; potassium, 3.5 to 5.1 mEq/L; chloride, 98 to 106 mEq/L; and bicarbonate (venous), 22 to 30 mEq/L. The only abnormal value identified above is the serum potassium level, which would be the one of most concern to the nurse because of potential cardiac arrhythmias.

Answer to Question 2

4

Rationale: Nix is an over-the-counter antilice product that kills both lice and eggs with one ap-plication and has residual activity for 10 days. It is applied to the hair after shampooing and left for 10 minutes before rinsing out. The hair should not be shampooed for 24 hours after the rins-ing treatment.
