Advanced Nutrition for Health and
Healthcare Practice Multiple Choice
Questions (MCQs) with Answers and
Explanations (Chapters 1–23)
1. A 68-year-old patient recovering from hip surgery has experienced significant weight
loss and poor wound healing despite consuming an adequate number of calories. Which
nutritional factor is most likely contributing to delayed tissue repair?
A. Excess carbohydrate intake
B. Excessive vitamin C supplementation
C. Inadequate protein intake
D. Excess dietary fiber
Explanation: Protein provides the amino acids required for collagen synthesis, immune function,
and tissue repair. Even with sufficient caloric intake, inadequate protein intake can impair
wound healing and recovery after surgery.
2. A nurse evaluates a patient's food diary and notes frequent consumption of ultra-
processed foods high in sodium and saturated fat. Which long-term outcome is most
strongly associated with this dietary pattern?
A. Improved bone mineral density
B. Increased risk of cardiovascular disease
C. Reduced insulin resistance
D. Enhanced immune function
Explanation: Diets high in sodium, saturated fats, and processed foods contribute to
hypertension, dyslipidemia, inflammation, and increased cardiovascular disease risk.
3. During nutritional assessment, which anthropometric measure provides the best estimate
of central adiposity associated with metabolic syndrome?
A. Body mass index (BMI)
B. Waist circumference
C. Mid-upper arm circumference
D. Skinfold thickness
Explanation: Waist circumference reflects abdominal fat accumulation, which is more closely
associated with insulin resistance, cardiovascular disease, and metabolic syndrome than BMI
alone.
, 4. A hospitalized patient develops edema despite normal body weight. Which laboratory
value would most likely explain this finding?
A. Elevated hemoglobin
B. Increased serum glucose
C. Low serum albumin
D. Elevated serum calcium
Explanation: Albumin maintains plasma oncotic pressure. Hypoalbuminemia allows fluid to
shift into interstitial tissues, causing edema.
5. Which characteristic distinguishes a nutrient-dense food from an energy-dense food?
A. It contains more calories than nutrients.
B. It provides substantial nutrients relative to calorie content.
C. It contains only vitamins and minerals.
D. It excludes dietary fats.
Explanation: Nutrient-dense foods supply vitamins, minerals, fiber, and other beneficial
nutrients while providing relatively few calories.
6. A patient with lactose intolerance can generally tolerate which dairy product most
effectively?
A. Whole milk
B. Sweetened condensed milk
C. Yogurt containing live bacterial cultures
D. Evaporated milk
Explanation: Live bacterial cultures partially digest lactose, improving tolerance in many
individuals with lactose intolerance.
7. During digestion, the majority of nutrient absorption occurs in which anatomical
location?
A. Stomach
B. Small intestine
C. Large intestine
D. Esophagus
Explanation: The small intestine provides extensive absorptive surface area through villi and
microvilli, making it the principal site of nutrient absorption.
8. Which hormone primarily stimulates glucose uptake into skeletal muscle following a
carbohydrate-rich meal?
