Question 1

A DTR is working in a WIC clinic. WIC primarily serves which population group?

Accepted Answer

Low-income women who are pregnant, postpartum, or breastfeeding, and children up to age 5

Answer

WIC (Women, Infants, and Children) serves low-income pregnant, postpartum, and breastfeeding women, infants, and children up to age 5 who are at nutritional risk.

Question 2

The nitrogen balance study of a patient reveals nitrogen intake of 14 g/day and urinary urea nitrogen (UUN) of 10 g/day. Using a fecal/sweat loss factor of 4, the nitrogen balance is:

Accepted Answer

0 g/day

Answer

Nitrogen balance = N intake − (UUN + 4) = 14 − (10 + 4) = 0, indicating equilibrium.

Question 3

Which specialized enteral formula would be most appropriate for a patient with severe chronic obstructive pulmonary disease (COPD) requiring ventilatory support?

Accepted Answer

Low-carbohydrate, high-fat formula

Answer

High-fat, low-carbohydrate formulas reduce CO2 production (lower respiratory quotient), which benefits patients with compromised respiratory function.

Question 4

A DTR calculating energy needs uses the Mifflin-St Jeor equation for a sedentary male patient. After calculating REE, which activity factor should be applied?

Accepted Answer

1.2

Answer

A sedentary lifestyle (little or no exercise) corresponds to an activity factor of 1.2 when applied to the Mifflin-St Jeor REE.

Question 5

A patient receiving continuous tube feeding via nasogastric tube has a gastric residual volume (GRV) of 550 mL. What is the most appropriate action?

Accepted Answer

Hold the feeding and notify the care team

Answer

A GRV of 500 mL or greater is typically the threshold to hold enteral feedings and reassess, as it may indicate delayed gastric emptying and aspiration risk.
