Nutrition Proctored Exam | Actual Q&A
with Rationale (NURS225 Final Exam) |
West Coast University
1. A nurse is teaching a client about the caloric value of macronutrients. Which of the
following information should the nurse include regarding the energy provided by lipids?
A. 9 kcal/g
B. 4 kcal/g
C. 7 kcal/g
D. 12 kcal/g
Answer: A
Rationale: Lipids provide the highest energy density of all macronutrients at 9 calories per
gram. In contrast, proteins and carbohydrates provide only 4 calories per gram.
Understanding these values is crucial for nurses when calculating a patient’s total daily
caloric intake.
2. A client is diagnosed with a deficiency in Vitamin K. Which of the following physiological
processes is most likely to be affected?
A. Visual acuity in low light
B. Synthesis of prothrombin for blood clotting
,C. Collagen synthesis for wound healing
D. Calcium absorption in the gut
Answer: B
Rationale: Vitamin K is essential for the hepatic synthesis of several blood-clotting factors,
including prothrombin. Without adequate Vitamin K, the body cannot effectively manage
coagulation, leading to increased bleeding risks. Nurses must educate patients on
anticoagulant therapy about consistent Vitamin K intake.
3. Which of the following instructions should the nurse provide to a client seeking to increase
their intake of complex carbohydrates?
A. Consume more fruit juices and honey
B. Focus on low-fat dairy products
C. Increase consumption of whole grains and legumes
D. Choose white bread and refined pastas
Answer: C
Rationale: Complex carbohydrates consist of long chains of glucose molecules and are
found in whole grains, beans, and vegetables. These foods take longer to digest and provide
a more sustained energy release compared to simple sugars. Increasing fiber intake
through these sources also promotes gastrointestinal health.
, 4. A nurse is caring for a patient with a pressure injury. Which nutrient is most critical for
tissue repair and collagen formation?
A. Vitamin D
B. Vitamin B12
C. Vitamin C
D. Vitamin E
Answer: C
Rationale: Vitamin C, also known as ascorbic acid, is a vital cofactor in the synthesis of
collagen, which provides structural integrity to skin and tissues. It also acts as an
antioxidant that protects cells from damage during the inflammatory phase of healing.
Ensuring adequate Vitamin C intake is a standard part of wound management protocols.
5. What is the recommended weight gain for a pregnant woman with a pre-pregnancy Body
Mass Index (BMI) within the normal range (18.5 to 24.9)?
A. 11 to 20 lbs
B. 25 to 35 lbs
C. 15 to 25 lbs
D. 28 to 40 lbs
Answer: B
