Answer to Question 1

B
PEG-ELS solutions provide an isosmotic solution and do not cause dehydration or electrolyte imbalance. They are safe to use in patients with renal impairment or cardiovascular disease. This patient's laboratory values suggest renal impairment. Sodium phosphate products can cause kid-ney damage; giving them with less fluid only increases this possibility. Reducing the dietary in-take of sodium is not recommended. Suppositories are not effective bowel cleansing agents.

Answer to Question 2

A
Patients who abuse cocaine, opioids, and other such drugs also frequently abuse clonidine, so this agent would not be the best choice for this patient. The other drugs do not share this abuse potential.
