1. How many kilocalories are provided by one gram of dietary carbohydrates?
A. 9 kcal/g
B. 7 kcal/g
C. 4 kcal/g
D. 12 kcal/g
Correct Answer: C
Expert Explanation: Carbohydrates are the primary source of energy for the body and
provide 4 kilocalories for every gram consumed. This is the same energy density as protein.
Fats are more energy-dense, providing 9 kilocalories per gram.
2. Which macronutrient is primarily responsible for tissue building and wound healing?
A. Lipids
B. Carbohydrates
C. Vitamins
D. Proteins
Correct Answer: D
,Expert Explanation: Proteins consist of amino acids which are the building blocks of the
body. They are essential for the repair of tissues, such as skin and muscle, especially after
surgery or injury. A patient with a pressure ulcer would require increased protein intake to
support healing.
3. The nurse is teaching a patient about the body’s stored form of carbohydrates. Which term
should the nurse use?
A. Glycogen
B. Fructose
C. Glucose
D. Starch
Correct Answer: A
Expert Explanation: Glycogen is the storage form of glucose in animals and humans. It is
primarily stored in the liver and muscle tissues to be used when blood glucose levels drop.
Starch is the storage form of glucose found in plants.
4. Which of the following is considered a fat-soluble vitamin?
A. Vitamin D
B. Vitamin B12
C. Vitamin C
D. Folate
, Correct Answer: A
Expert Explanation: Vitamins A, D, E, and K are fat-soluble, meaning they are stored in the
body’s fatty tissue and liver. Vitamin C and the B-complex vitamins are water-soluble and
excreted in urine if consumed in excess. Fat-soluble vitamins require bile for absorption in
the small intestine.
5. A patient has a BMI of 28. How should the nurse classify this finding?
A. Underweight
B. Overweight
C. Normal weight
D. Obese
Correct Answer: B
Expert Explanation: A Body Mass Index (BMI) between 25 and 29.9 is classified as
overweight. Normal weight is defined as a BMI between 18.5 and 24.9. Obese is defined as a
BMI of 30 or higher.
6. What is the primary function of dietary fiber in the human body?
A. Providing immediate cellular energy
B. Promoting regular bowel movements
