Question 1 of 5
A pregnant woman at 36 weeks' gestation is followed for PIH and develops proteinuria. To increase protein in her diet, which of the following foods will provide the greatest amount of protein when added to her intake of 100 mL of milk?
Correct Answer: B
Rationale: This choice would provide more unwanted fat and sugar than protein. Skim milk would add protein. Eggs are good sources of protein while low in fat and calories. The benefit of protein from ice cream would be outweighed by the fat content. Chocolate syrup has caffeine, which is contraindicated or limited in pregnancy. Although most animal proteins are higher in protein than plant proteins, gelatin is not. It loses protein during the processing for food consumption.
