Answer to Question 1

ANS: B
Orlistat works by altering the absorption of fats. It does not affect how energy is stored, the metabolic rate, or the appetite.

Answer to Question 2

ANS: C
Because orlistat works by reducing fat absorption, fat-soluble vitamins are not absorbed as well. Patients should take a multivitamin containing vitamins A, D, E, and K. The increased fat is lost in stools, resulting in fatty, oily stools and fecal incontinence. These are expected side effects but are not dangerous and can be managed with bulk-forming laxatives. Orlistat is used for long-term weight loss and should be given up to 2 years to sustain weight loss. Dark urine and light-colored stools indicate possible liver damage and the need to discontinue the drug until liver damage has been ruled out.
