MyLab Questions: Obesity, Exam #2
review questions
The nurse is teaching about the pathophysiological changes that cause obesity
and the minimum amount of kilocalories required to sustain life.
Which information should the nurse include?
How a decrease in basal metabolic rate contributes to weight gain
How increasing resting energy expenditure causes obesity
How to calculate body mass index
How to determine nutrient density - CORRECT ANSWER-How a decrease in
basal metabolic rate contributes to weight gain
The nurse is describing the pathophysiology of obesity, so the answer should
explain that the basal metabolic rate is the "cost" of staying alive and is the
minimum number of kilocalories needed at rest to maintain life-sustaining
activities. The resting metabolic rate per kilogram of body weight is lower in an
obese person compared with a normal-weight person. The other answers are
incorrect because the resting energy expenditure is also typically lower, not
higher, in an obese person; the body mass index is an indirect measure of the
amount of body fat, and the nutrient density refers to the ratio of good nutrients to
the calories a food contains, but neither choice explains the pathophysiological
cause of obesity.
A patient diagnosed with hypertension has a calculated body mass index (BMI)
of 36 and the following lab results: LDL 190 mg/dL, HDL 40 mg/dL, total
cholesterol 240 mg/dL, triglycerides 500 mg/dL.
Based on this assessment data, how should the nurse classify the patient's
weight?
,Obesity class II
Normal weight
Obesity class I
Overweight - CORRECT ANSWER-Obesity class II
The most common way to determine if a person is overweight or obese is to
calculate body mass index (BMI). The diagnosis of hypertension and the lab
results indicate hyperlipidemia, which are two comorbidities of obesity. Based on
this information, a BMI greater than 35 with two or more comorbidities is defined
as obesity class II. Normal weight is a BMI under 18.5-24.9 with no comorbidities.
BMI between 25 and 30 is classified as overweight. A BMI of 30-34.9 with two or
more comorbidities is classified as obesity class I.
An obese patient has been prescribed a lipase inhibitor, orlistat (Xenical), for
weight loss.
Which finding is most important to report to the healthcare provider?
ANSWER
The patient is having recurrent liquid stools.
The patient feels bloated after meals.
The patient is experiencing a weight-loss plateau.
The patient is pale and has extensive bruising. - CORRECT ANSWER-The
patient is pale and has extensive bruising.
A 60-year-old female patient is concerned about gaining weight because she is
going through menopause.
,Which factor should the nurse teach the patient to help prevent weight gain as
she ages?
ANSWER
Drinking more water
Eliminating the intake of bread, potatoes, and rice
Focusing on portion sizes
Restricting the intake of carbohydrate-dense foods - CORRECT
ANSWER-Focusing on portion sizes
Education is a key to promoting nutritional wellness and preventing
nutrition-related alterations, including obesity. Patients may benefit from teaching
related to portion sizes. Water is an essential nutrient; however, drinking more
water will not prevent weight gain as the patient ages. The patient should not be
instructed to avoid particular foods and food groups such as carbohydrates and
grains because these foods provide essential nutrients and vitamins to maintain
health.
The nurse is teaching a patient about the recommended amounts of food from
animal and plant sources.
Which menu selections made by the patient indicate that the nurse's teaching
about diet has been understood?
ANSWER
3 oz of lean beef, 2 oz of low-fat cheese, and a sliced tomato
3 oz of roast pork, a cup of corn, and a cup of carrot sticks
A cup of tossed salad and nonfat dressing topped with a chicken breast
, A half cup of tuna mixed with nonfat mayonnaise and a half cup of celery -
CORRECT ANSWER-3 oz of roast pork, a cup of corn, and a cup of carrot sticks
This selection is most consistent with the recommendation of the American
Institute for Cancer Research that one third of the diet should be from animal
sources and two thirds from plant source foods. The other choices all have
higher ratios of animal-origin foods to plant-source foods than would be
recommended. The following image is a good representation of the serving size
for each food item, except that the patient should only have one pork chop and
more green beans. Swapping out sweet potatoes for the regular mashed
potatoes would make this meal an even better selection.
The nurse is assessing a patient who is obese.
Which is the most important observation that the nurse should make?
The patient's dislike of vegetables
The patient's self-reported shortness of breath after brisk walking
The patient's difficulty standing from a seated position
The patient's negative self-image caused by obesity - CORRECT ANSWER-The
patient's difficulty standing from a seated position
When planning activities for obese patients, it is important to note self-imposed
restrictions, such as difficulty moving from a sitting to standing position in order to
anticipate for these difficulties while developing a successful workout plan.
Knowing that the patient does not like vegetables is good, but there are many
other options to help them achieve balanced nutrition without having to directly
eat vegetables. Shortness of breath is a commonly reported symptom of obese
people who have performed physical activity. Finally, it is important to note
negative self-image and issues with self-esteem, but it is easier to focus on the
short-term goal of establishing an exercise routine, because this has the potential
of leading to higher self-esteem as the patient loses weight.
