NURS 225 Exam 2 V1 | NURS 225 Nutrition
Proctored Exam | Actual Q&A with
Rationale (NURS225 Exam 2) | West Coast
University
1. A nurse is reviewing the primary function of carbohydrates in the body during a nutritional
assessment. Which statement should the nurse identify as the most accurate?
A. Carbohydrates provide the main source of energy for cellular metabolism.
B. Carbohydrates are the primary structural component of muscle tissue.
C. Carbohydrates act as the primary storage vehicle for fat-soluble vitamins.
D. Carbohydrates are essential for the synthesis of all steroid hormones.
Answer: A
Rationale: Carbohydrates are the body’s preferred source of fuel, particularly for the brain
and nervous system. Glucose is the specific end-product used for ATP production in cellular
respiration. While other macronutrients provide energy, carbohydrates are the most
efficient and readily available source.
2. A client asks the nurse why fiber is important if it cannot be digested. Which response by
the nurse is most appropriate?
A. Fiber adds bulk to the stool and promotes regular bowel movements.
B. Fiber is converted into essential amino acids by the liver.
,C. Fiber provides a significant amount of caloric energy to the daily total.
D. Fiber increases the absorption of cholesterol in the small intestine.
Answer: A
Rationale: Insoluble fiber increases stool mass and speeds up the transit time through the
colon, preventing constipation. Soluble fiber can also assist in lowering blood cholesterol
by binding with bile acids. Nurses should encourage fiber intake to support overall
gastrointestinal health and metabolic stability.
3. A nurse is educating a client on the differences between saturated and unsaturated fats.
Which food item should the nurse identify as containing primarily saturated fats?
A. Whole-milk dairy products
B. Avocado
C. Canola oil
D. Walnuts
Answer: A
Rationale: Saturated fats are typically solid at room temperature and are predominantly
found in animal products such as meat and full-fat dairy. Excessive intake of these fats is
linked to higher LDL cholesterol levels and increased cardiovascular risk. In contrast, plant
oils and nuts usually contain higher proportions of heart-healthy unsaturated fats.
, 4. When assessing a client for protein deficiency, which clinical finding is most characteristic
of Kwashiorkor?
A. Severe wasting of subcutaneous fat
B. Hyperactivity and increased appetite
C. Edema in the lower extremities and abdomen
D. Yellowing of the sclera
Answer: C
Rationale: Kwashiorkor is a form of severe protein malnutrition characterized by
adequate calorie intake but insufficient protein. This leads to a decrease in serum albumin,
which causes fluid to shift into the interstitial spaces, resulting in edema. It is distinguished
from Marasmus, which involves a general deficiency of both calories and protein.
5. A nurse is teaching a patient about complete proteins. Which of the following foods should
be included as an example?
A. Soybeans
B. Whole grain bread
C. Peanut butter
D. Lentils
Answer: A
