1. A patient has a body mass index of 27 and weighs 160 pounds. What is this patient considered to be?

  1. A)  Underweight
  2. B)  Overweight
  3. C)  Obese
  4. D)  Desired weight

Ans: B
Feedback:
Overweight is defined as a body mass index of 25 to 29.9 kg/m2. The patient is not underweight, obese, or at the desired weight. Obesity cannot be determined solely on the basis of body weight.

2. When the nurse is educating a women’s group on obesity and healthy eating, which of the following statements is most accurate?

  1. A)  Consuming 3500 extra calories in a week will result in 1 pound of fat.
  2. B)  Extra calories are converted to amino acids or protein.
  3. C)  Food that contains large amounts of fat stimulates energy.
  4. D)  Women will typically expend more energy than men because of muscle tissue.

Ans: A
Feedback:
Consuming an extra 500 calories each day for a week results in 3500 excess calories, or 1 pound of fat. Excess calories are converted to triglycerides, not amino acids. Foods that contain carbohydrates and protein stimulate energy expenditure. Men expend more energy than women.

3. A school nurse is in the planning stages of a health promotion campaign that will address childhood obesity. Of the following, which is an environmental factor believed to have contributed most to increased weight in children?

  1. A)  Playing video games
  2. B)  Genetic changes
  3. C)  Increased social acceptance of obesity
  4. D)  Increased incidence of depression

Ans: A
Feedback:
For both adults and children, increased time watching television, playing video and computer games, and working on computers contributes to less physical activity and promotes weight gain. Depression, social factors, and genetic factors are not environmental influences.

  2. B)  Migraine headache
  3. C)  Scoliosis

Overweight and obese children are at risk for developing type 2 diabetes. Overweight children are not particularly prone to developing glaucoma, migraine headache, or scoliosis.

  1. A)  Dry mouth
  2. B)  Hypernatremia
  3. C)  Fatigue
  4. D)  Hypoglycemia

Ans: A
Feedback:
The most commonly reported adverse effects of phentermine are nervousness, dry mouth, constipation, and hypertension. Hypernatremia, fatigue, and hypoglycemia are not adverse effects of phentermine.

6. An obese patient has asked her nurse practitioner to prescribe sibutramine. What variable will most affect the nurse’s decision?

  1. A)  Sibutramine has been taken off the market due to adverse cardiovascular effects.
  2. B)  Sibutramine is prohibitively expensive and is not covered by most insurers.
  3. C)  The use of sibutramine requires weekly blood work.
  4. D)  Sibutramine must be combined with an anticholinergic drug in order to potentiate

    its effects.

Ans: A

Feedback:

Until recently, health care providers used sibutramine, a drug that suppresses appetite by inhibiting the reuptake of the neurotransmitters norepinephrine and serotonin, in the management of obesity. The drug is no longer available in the United States because a clinical study demonstrated an increased risk of cardiovascular events such as heart attack and stroke with its use.
