Answer to Question 1

2

Rationale 1:It speeds up your metabolism is incorrect. Orlistat blocks lipase in the GI tract.
Rationale 2: Orlistat blocks the enzyme lipase in the GI tract, which blocks the absorption of fats.
Rationale 3:Orlistat does not cause nausea.
Rationale 4:Orlistat does not suppress appetite.

Global Rationale: Orlistat blocks the enzyme lipase in the GI tract, which blocks the absorption of fats. It produces only a small decrease in weight compared to placebos.

Answer to Question 2

1

Rationale 1:Despite the public's desire for effective drugs to promote weight loss, there are few drugs available. Diet and exercise need to be included in the plan of care for an obese client.
Rationale 2:The nurse needs to be knowledgeable about the treatment plan for the client.
Rationale 3:Medications, diet, and exercise are a comprehensive plan of care for a client diagnosed with obesity.
Rationale 4:Depression can be linked to obesity. A comprehensive plan of diet, exercise, and medication is necessary.

Global Rationale: Current pharmacologic strategies for weight management focus on two mechanisms: lipase inhibitors and anorexiants. Diet and exercise are critical to the management of an obese client.
