,1. A nurse is calculating a client's body mass index (BMI). Which BMI
range is classified as normal weight?
A. Less than 18.5
B. 18.5-24.9
C. 25-29.9
D. 30 or greater
Correct Answer: B. 18.5-24.9
Rationale: A BMI of 18.5-24.9 kg/m2 is classified as normal weight. Below
18.5 is underweight, 25-29.9 is overweight, and 30 or greater is obese.
2. A nurse is teaching a client about complete proteins. Which food
source provides a complete protein?
A. Black beans
B. Rice
C. Eggs
D. Corn
Correct Answer: C. Eggs
Rationale: Eggs are a complete protein source, containing all nine essential
amino acids. Plant sources like beans, rice, and corn are typically incomplete
proteins unless combined.
3. A nurse is assessing a client for protein-energy malnutrition. Which
laboratory value best reflects visceral protein status?
A. Serum albumin
B. Hemoglobin A1c
C. Fasting blood glucose
D. Serum sodium
Correct Answer: A. Serum albumin
Rationale: Serum albumin is a marker of visceral protein status and nutritional
reserve, though it has a long half-life (~20 days) and may not reflect acute
changes; prealbumin is more sensitive to short-term changes.
,4. A nurse is teaching about carbohydrates. Which statement indicates
the client understands the difference between simple and complex
carbohydrates?
A. 'Whole grains are a simple carbohydrate.'
B. 'Table sugar is an example of a complex carbohydrate.'
C. 'Complex carbohydrates like whole grains provide more sustained energy
and fiber.'
D. 'Simple and complex carbohydrates provide the same nutritional value.'
Correct Answer: C. 'Complex carbohydrates like whole grains provide
more sustained energy and fiber.'
Rationale: Complex carbohydrates (whole grains, legumes) contain fiber and
provide more sustained energy release compared to simple carbohydrates
(table sugar), which cause rapid blood glucose spikes.
5. A nurse is calculating caloric needs for a client. How many kilocalories
are provided by 1 gram of fat?
A. 4 kcal
B. 7 kcal
C. 9 kcal
D. 12 kcal
Correct Answer: C. 9 kcal
Rationale: Fat provides 9 kcal/gram, more than double that of carbohydrates
and protein (4 kcal/gram each); alcohol provides 7 kcal/gram.
6. A nurse is using anthropometric measurements to assess nutritional
status. Which measurement assesses subcutaneous fat stores?
A. Mid-arm circumference
B. Triceps skinfold thickness
C. Height
D. Waist-to-hip ratio only
Correct Answer: B. Triceps skinfold thickness
Rationale: Triceps skinfold thickness is an anthropometric measurement used
to estimate subcutaneous fat stores and overall body fat percentage.
, 7. A nurse is calculating a client's ideal body weight percentage to assess
malnutrition risk. A client at what percentage of ideal body weight is
considered to have severe malnutrition?
A. 90-100%
B. 80-90%
C. 70-79%
D. Less than 70%
Correct Answer: D. Less than 70%
Rationale: Less than 70% of ideal body weight generally indicates severe
malnutrition; 80-90% suggests mild, and 70-79% suggests moderate
malnutrition.
8. A nurse is teaching a client about dietary fiber. Which health benefit is
associated with adequate fiber intake?
A. Decreased risk of constipation and improved bowel regularity
B. Increased risk of hyperlipidemia
C. Decreased satiety after meals
D. Increased blood glucose spikes
Correct Answer: A. Decreased risk of constipation and improved bowel
regularity
Rationale: Adequate dietary fiber intake promotes bowel regularity, decreases
constipation risk, helps lower cholesterol, and improves satiety and glycemic
control.
9. A nurse is reviewing a client's nutrition screening tool (e.g., MST or
MUST). Which finding would trigger a referral to a registered dietitian?
A. Stable weight over the past 6 months
B. Unintentional weight loss of 10 lbs (4.5 kg) over the past month with
decreased appetite
C. Consistent, adequate oral intake
D. BMI within normal range with no recent changes
Correct Answer: B. Unintentional weight loss of 10 lbs (4.5 kg) over the
past month with decreased appetite
Rationale: Unintentional weight loss combined with decreased appetite are
red flags on nutrition screening tools that warrant a referral for comprehensive
dietitian assessment.
