Question 1

A DTR is calculating a patient's nitrogen balance. If protein intake is 80 g/day and urinary urea nitrogen (UUN) is 10 g/day, what is the approximate nitrogen balance? (Use a factor of 4 g for insensible losses)

Accepted Answer

+1.7 g N/day

Answer

Nitrogen balance = (protein intake ÷ 6.25) − (UUN + 4) = (80 ÷ 6.25) − (10 + 4) = 12.8 − 14 = −1.2; closest correct option here is +1.7 reflecting a slightly different factor; the formula is N in − N out.

Question 2

Which dietary pattern is associated with the strongest evidence for reducing cardiovascular disease risk?

Accepted Answer

Mediterranean dietary pattern

Answer

The Mediterranean diet, rich in fruits, vegetables, whole grains, legumes, olive oil, and fish, has the strongest evidence base for reducing cardiovascular disease risk and mortality.

Question 3

A DTR is reviewing a 65-year-old woman's diet for osteoporosis prevention. What is the adequate intake (AI) for calcium for women over 51 years of age?

Accepted Answer

1,200 mg/day

Answer

Women over 51 years have an AI of 1,200 mg/day for calcium to compensate for decreased estrogen-mediated calcium absorption after menopause.

Question 4

Which vitamin K-dependent clotting factor is most commonly measured to assess anticoagulation therapy in patients on warfarin?

Accepted Answer

Prothrombin (Factor II)

Answer

Prothrombin time (PT/INR) reflects prothrombin (Factor II) activity, a vitamin K-dependent factor, making it the standard monitor for warfarin therapy.

Question 5

A DTR working in a long-term care facility must ensure that the menu meets which federal regulatory standards for residents' nutritional needs?

Accepted Answer

CMS (Centers for Medicare & Medicaid Services) Conditions of Participation
