NURS 225 Exam 1 V2 | NURS 225 Nutrition
Proctored Exam | Actual Q&A with
Rationale (NURS225 Exam 1) | West Coast
University
1. A nurse is conducting a nutritional assessment on a client who adheres to a vegan diet.
Which of the following nutrients should the nurse identify as a potential deficiency requiring
supplementation?
A. Vitamin C
B. Vitamin B12
C. Fiber
D. Potassium
Answer: B
Rationale: Vitamin B12 is primarily found in animal-based products, putting individuals
on strict vegan diets at risk for deficiency. The nurse must monitor for signs of pernicious
anemia or neurological changes in these clients. Adequate education on fortified cereals or
oral supplements is necessary for maintaining long-term health.
2. When teaching a group of adult clients about the differences between simple and complex
carbohydrates, which information should the nurse prioritize?
A. Complex carbohydrates take longer to digest and provide a steady glucose level.
,B. Simple carbohydrates provide sustained energy release.
C. Complex carbohydrates are found primarily in honey and fruits.
D. Simple carbohydrates have a higher thermic effect.
Answer: A
Rationale: Complex carbohydrates consist of long chains of glucose molecules that require
more enzymatic activity to break down. This slower digestion process results in a more
gradual rise in blood glucose levels compared to the rapid spikes caused by simple sugars.
Promoting the intake of whole grains and legumes is a key strategy for glucose
management.
3. A nurse is reviewing the laboratory results of a client with suspected protein-calorie
malnutrition. Which lab value is the most sensitive indicator of current nutritional status?
A. Transferrin
B. Albumin
C. Prealbumin
D. Hemoglobin
Answer: C
Rationale: Prealbumin has a much shorter half-life of approximately two days compared to
albumin’s twenty-day half-life. This makes prealbumin a more reliable marker for
, assessing acute changes in a client’s nutritional condition. The nurse should advocate for
this lab test when monitoring the effectiveness of nutritional interventions.
4. A client asks the nurse about the purpose of dietary fiber. Which response by the nurse is
the most accurate regarding insoluble fiber?
A. It slows down gastric emptying to keep you full.
B. It dissolves in water to form a gel-like substance.
C. It adds bulk to the stool and promotes regular bowel movements.
D. It lowers blood cholesterol levels by binding to bile.
Answer: C
Rationale: Insoluble fiber does not dissolve in water and acts as a mechanical stimulant in
the digestive tract to speed up transit time. This process is essential for preventing
constipation and maintaining overall colonic health. Sources include wheat bran,
vegetables, and whole grains.
5. A nurse is assessing a client’s Body Mass Index (BMI). The client weighs 75 kg and is 1.75
meters tall. Which classification does the nurse identify?
A. Underweight
B. Normal weight
C. Overweight
D. Obese
