Answer to Question 1

Correct Answer: 2
Rationale 1: The presence of an oxygen cannula is not associated with preparation for the test.
Rationale 2: Nitrogen balance is determined by comparing the grams of protein taken in to the urinary nitrogen output for 24 hours. Accurate food intake is essential.
Rationale 3: Urine output is not collected for 48 hours for this test.
Rationale 4: The client must have protein intake during the testing time.

Answer to Question 2

Correct Answer: 3
Rationale 1: The words lighter or reduced calories only mean that this version of the food is lower in calories than a previous version, but the food can still be very high in calories.
Rationale 2: There is no special label letter that indicates foods lighter in calories.
Rationale 3: In order to qualify as a low-calorie food in a 2,000-calorie diet, the food must have less than 40 calories per serving.
Rationale 4: Foods that are lower in fat also contain fewer calories, but low fat is considered less than 5.
