Answer to Question 1

ANS: C
Patients with prolonged vomiting and diarrhea become hypovolemic. A solution to replace extracellular volume is 0.9 sodium chloride, which is an isotonic solution. 0.225 and 0.45 sodium chloride are hypotonic. 3 sodium chloride is hypertonic.

Answer to Question 2

ANS: C
Total parenteral nutrition is an intravenous solution composed of nutrients and electrolytes to replace the ones the patient is not eating or losing. TPN does not stimulate the appetite. TPN does not contain blood pressure medication or antibiotics.
