A DTR is working in a WIC clinic. WIC primarily serves which population group?
Answer: Low-income women who are pregnant, postpartum, or breastfeeding, and children up to age 5
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.
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:
Answer: 0 g/day
Nitrogen balance = N intake − (UUN + 4) = 14 − (10 + 4) = 0, indicating equilibrium.
Which specialized enteral formula would be most appropriate for a patient with severe chronic obstructive pulmonary disease (COPD) requiring ventilatory support?
Answer: Low-carbohydrate, high-fat formula
High-fat, low-carbohydrate formulas reduce CO2 production (lower respiratory quotient), which benefits patients with compromised respiratory function.
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?
Answer: 1.2
A sedentary lifestyle (little or no exercise) corresponds to an activity factor of 1.2 when applied to the Mifflin-St Jeor REE.
A patient receiving continuous tube feeding via nasogastric tube has a gastric residual volume (GRV) of 550 mL. What is the most appropriate action?
Answer: Hold the feeding and notify the care team
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.
Which food component in excess is most directly linked to hypertension and fluid retention in the general population?
Answer: Dietary sodium
Excess dietary sodium promotes fluid retention and increases blood pressure, making sodium restriction a cornerstone of hypertension management.
A DTR completing a food service production record notices that 100 portions were planned but only 85 were served. What is the leftover percentage?
Answer: 15%
(100 − 85) ÷ 100 × 100 = 15% leftover, indicating 15% of planned portions were not served.
