SECTION 1: NUTRITION ASSESSMENT AND BASIC PRINCIPLES (Questions 1-10)
**Question 1**
A nurse is teaching a client about dietary sources of complete protein. Which of the
following foods should the nurse include as a complete protein?
A) Lentils
B) Brown rice
C) Eggs
D) Peanut butter
**ANswer:** C) Eggs
**rATIoNAle:** Complete proteins contain all nine essential amino acids. Animal
sources (eggs, meat, poultry, fish, dairy, and soy) are complete proteins. Plant sources
(lentils, rice, beans, peanut butter) are incomplete proteins, though combinations can
create complementary proteins. Eggs are considered the gold standard reference
protein for quality.

**Question 2**
,A nurse is calculating the body mass index (BMI) of a client who weighs 75 kg and is
1.75 m tall. What is the correct BMI?
A) 18.5
B) 22.4
C) 24.5
D) 28.1
**ANswer:** C) 24.5
**rATIoNAle:** BMI = weight (kg) ÷ height (m)² = 75 ÷ (1.75 × 1.75) = 75 ÷ 3.0625 = 24.49
≈ 24.5. BMI classifications: Underweight <18.5, Normal 18.5-24.9, Overweight 25-29.9,
Obesity ≥30.

**Question 3**
A nurse is educating a client about the function of carbohydrates. Which statement by
the client indicates understanding?
A) "Carbohydrates are primarily stored as adipose tissue."
B) "Carbohydrates provide the body's main source of energy."
C) "Carbohydrates should be avoided to lose weight."
D) "Carbohydrates are only found in sugary foods."
**ANswer:** B) "Carbohydrates provide the body's main source of energy."
**rATIoNAle:** Carbohydrates are the body's preferred and primary energy source,
providing 4 kcal/g. They are broken down into glucose, which fuels the brain, muscles,
and other tissues. Complex carbohydrates (whole grains, vegetables) are healthier than
, simple sugars. Carbohydrates are not primarily stored as fat unless consumed in
excess.

**Question 4**
A nurse is reviewing laboratory results for a client who is malnourished. Which
laboratory value would the nurse expect to be decreased?
A) Hemoglobin
B) White blood cell count
C) Albumin
D) All of the above
**ANswer:** D) All of the above
**rATIoNAle:** Malnutrition affects multiple laboratory parameters. Hemoglobin
decreases due to iron, folate, or B12 deficiency (anemia). Albumin decreases due to
inadequate protein intake (negative acute phase reactant). White blood cell count may
decrease due to protein-energy malnutrition impairing immune function. Prealbumin is
a more sensitive marker of acute protein malnutrition.

**Question 5**
A nurse is teaching a client about the difference between saturated and unsaturated
fats. Which statement is correct?
A) Saturated fats are liquid at room temperature
B) Unsaturated fats are solid at room temperature
