QUESTION 1
The nurse is teaching a client about nutrition and explains that the primary
function of nutrition is to perform which action for the body?
A. Provide the body with necessary nutrients for daily tasks
B. Eliminate all toxins from the digestive system
C. Regulate body temperature through metabolic processes
D. Create energy stores for emergency situations
✓ Correct Answer: A
Rationale: Nutrition provides the body with the nutrients it needs to
perform its daily tasks. This encompasses the essential function of
supplying energy, building materials, and regulatory substances that
enable all bodily functions to operate effectively.
QUESTION 2
A client is consuming more than enough calories but still appears malnourished.
The nurse recognizes that this client may be experiencing which condition?
A. Overnutrition
B. Undernutrition
C. Malnutrition
D. Starvation
, ✓ Correct Answer: C
Rationale: Malnutrition is an imbalance of proper nutrients that can occur
even when caloric intake is adequate. This condition results from
consuming calories from sources that lack essential vitamins, minerals,
and other nutrients needed for optimal body function.
QUESTION 3
The nurse is assessing a client who exhibits self-starvation, food preoccupation,
compulsive exercising, and an absence of menstrual cycles. The nurse suspects
which eating disorder?
A. Bulimia nervosa
B. Binge eating disorder
C. Anorexia nervosa
D. Pica
✓ Correct Answer: C
Rationale: Anorexia nervosa literally means loss of appetite, but this is a
misnomer as the client is hungry but denies the hunger due to an irrational
fear of becoming fat. Characteristics include self-starvation, food
preoccupation and rituals, compulsive exercising, and often an absence of
menstrual cycles in women. Untreated, this condition can be fatal.
QUESTION 4
A client reports recurring periods of binge eating followed by self-induced
vomiting and laxative abuse. The nurse identifies these behaviors as consistent
with which disorder?
A. Anorexia nervosa
B. Bulimia nervosa
C. Binge eating disorder
D. Orthorexia
, ✓ Correct Answer: B
Rationale: Bulimia is characterized by recurring periods of binge eating
during which large amounts of food are consumed in a short period,
followed by purging through self-induced vomiting, abuse of laxatives
and/or diuretics, or periods of fasting. This cycle of bingeing and purging
distinguishes bulimia from other eating disorders.
QUESTION 5
The nurse is teaching a client about binge eating disorder and explains that this
condition is characterized by which behaviors?
A. Eating rapidly and consuming large amounts of food even when not hungry
B. Restricting food intake to fewer than 500 calories per day
C. Exercising compulsively for hours each day
D. Purging through self-induced vomiting after meals
✓ Correct Answer: A
Rationale: Binge eating disorder is characterized by episodes of binge
eating that include eating rapidly, eating large amounts of food even when
not feeling hungry, and feeling guilty or depressed after overeating. Unlike
bulimia, binge eating disorder does not involve compensatory purging
behaviors.
QUESTION 6
The nurse is assessing a client who is 20 percent above normal weight and has
poor dietary patterns including increased intake of sugar-sweetened beverages.
The nurse recognizes that this client is at risk for which health problems?
A. Type 2 diabetes, hypertension, and heart disease
B. Anemia and osteoporosis
C. Thyroid disorders and adrenal insufficiency
D. Autoimmune diseases and allergies
, ✓ Correct Answer: A
Rationale: Obesity is defined as being 15 to 20 percent above normal
weight and is associated with poor dietary patterns including increased
intake of sugars in sweetened soft drinks, foods, and meals of high energy
and low nutrient density. Clients with obesity are at risk for serious health
problems such as type 2 diabetes, hypertension, heart disease, stroke,
and some types of cancer.
QUESTION 7
The nurse is teaching a client about minerals and explains that inorganic
materials that form body parts and regulate nerve impulses are classified as
which type of nutrient?
A. Vitamins
B. Minerals
C. Carbohydrates
D. Lipids
✓ Correct Answer: B
Rationale: Minerals are inorganic materials that form body parts such as
teeth and bones, maintain acid-base neutrality, regulate nerve impulses,
osmotic pressure, and electrolyte balance. They are essential for
numerous physiological functions and must be obtained through the diet.
QUESTION 8
The nurse is counseling a client about dietary sources of calcium. Which foods
should the nurse recommend as rich sources of this major mineral?
A. Oranges, bananas, and dried fruits
B. Milk, cheese, sardines, and green vegetables
