Question: 43
Nutrient needs of infants diagnosed with bronchopulmonary dysplasia:
A. Are linked with linear growth
B. May include a resting energy expenditure 50% higher than that of normal
infants
C. May include use of diuretics to regulate water balance
D. All of the above
Answer: D
Nutrient needs of infants diagnosed with bronchopulmonary disease are linked
with linear growth (a measure of lung development), may include a resting energy
expenditure that is 50% higher than that of normal infants, and may include the
use of diuretics to regulate water balance. Bronchopulmonary disease is a
common lung disorder in premature infants which increases energy needs.
Diuretics are often needed to regulate water balance as a result of respiratory
compromise.
Question: 44
The following nutrition diagnosis is written in what type of format: “Poor
glycemic control is related to skipping use of oral hypoglycemic agents as
evidenced by random blood glucose levels greater than 200 mg/dl”.
A. SOAP note
B. POMR
C. PES statement
D. Continuity of care record
Answer: C
The nutrition diagnosis “Poor glycemic control is related to skipping use of oral
hypoglycemic agents as evidenced by random blood glucose levels greater than
200 mg/dl” is written as a PES statement (P is problem, E is etiology, S is signs or
symptoms). Problem = poor glycemic control, Etiology = skipping use of oral
hypoglycemic agents, S = blood glucose levels greater than 200 mg/dl.
Question: 45
Which dietary measures are recommended for treating hypercalcuria that is not
associated with renal stones?
A. Limiting calcium to 1000 mg per day
B. Increasing fluid intake to 2 liters per day
C. 400 IU vitamin D per day
D. Limiting animal protein to less than 1.7 g/kg per day
Answer: D
Limiting animal protein to less than 1.7 g/kg per day is recommended for the
treatment of hypercalcuria because excessive intakes of animal protein cause
calcium loss from the bones. A moderate calcium intake of 600-800 mg of
calcium per day is recommended, since lowering calcium intake results in
increased absorption. Increasing fluid intake does not prevent hypercalcuria.
Question: 46
Which of the following is a common side effect of immunosuppressive drug
therapy used in organ transplantation?
A. Sodium and fluid diuresis
B. Hyperphosphatemia
C. Hyperkalemia
D. Decreased vitamin C requirements
Answer: C
Hyperkalemia (elevated potassium levels) is a common side effect of
immunosuppressive drug therapy used in organ transplantation, as a result of
disturbances in renal hormone activity. Sodium and fluid retention and
hypophosphatemia are also side effects of immunosuppressive drugs.
Question: 47
Brown adipose tissue performs what function in the body:
A. Protects internal organs from injury
B. Storage site for triglycerides
C. Is considered to be “essential fat” that supports metabolic processes
D. Heat production and regulation of body temperature
Answer: D
Brown adipose tissue is believed to regulate heat production and body
temperature, particularly in infants who are susceptible to hypothermia. White
adipose tissue is the major type of fat in the body. It protects internal organs from
injury, stores triglycerides, and makes up the essential fat that supports many
metabolic processes.
Question: 48
Age-associated bone loss among the elderly:
A. Is always reversed with calcium supplementation
B. Can be prevented by cardiovascular exercise such as swimming
C. Affects both trabecular and cortical bone
D. May be slowed by the use of steroid drugs
Answer: C
Age-associated bone loss among the elderly affects both trabecular (spongy) and
cortical (hard) bone. Age-associated bone loss may be slowed by calcium
supplementation, through may not be reversed. Bone loss is slowed by weight-
bearing exercise, such as walking, aerobics, and weight training, and accelerated
by the use of steroid drugs.
Question: 49
Which of the following vitamins functions as a hormone?
A. Folic acid
B. Vitamin C
C. Vitamin E
D. Vitamin D
Answer: D
Vitamin D functions in the form calcitriol as a hormone in the regulation of body
calcium and phosphorus. It is also responsible for the formation of bone.
Question: 50
50. Which of the following is true for athletic amenorrhea, the loss of menstrual
periods caused by excessive exercise?
A. It results in irreversible bone loss
B. It may be successfully treated by increasing carbohydrate intake
C. It is treated by decreasing the intensity and amount of exercise
D. Both A and C
E. Both A and B
Answer: D
Athletic amenorrhea, the loss of menstrual periods caused by excessive exercise,
results in irreversible bone loss and is treated by decreasing the intensity and
amount of exercise. It is not helped by increasing intake of carbohydrates.
