QUESTION 1
A 35-year-old patient with Type 2 diabetes is being counseled on nutrition.
The nurse explains that complex carbohydrates are preferable to simple
sugars. Which of the following best describes why complex carbohydrates are
recommended?
A) They contain no calories and are risk-free for weight gain
B) They are absorbed more slowly, providing sustained energy and better blood
glucose control
C) They taste better and are more appealing to patients
D) They are only found in organic foods and are always healthier
E) They completely eliminate the need for insulin therapy
✓ CORRECT ANSWER: B) They are absorbed more slowly, providing sustained
energy and better blood glucose control
RATIONALE: Complex carbohydrates have a lower glycemic index and are digested
more slowly than simple sugars, resulting in a gradual rise in blood glucose levels.
,This steady energy release helps prevent rapid spikes in blood sugar, making them
ideal for diabetic patients. They also provide sustained energy throughout the day
and improve satiety. Options A and D are factually incorrect as complex
carbohydrates do contain calories and are found in many food sources. Option C is
subjective, and Option E is inaccurate as diet alone cannot eliminate the need for
insulin in all diabetic patients.

QUESTION 2
A nurse is assessing a patient's nutritional status. Which laboratory value is
the most sensitive indicator of recent nutritional changes?
A) Serum albumin
B) Total serum protein
C) Prealbumin (transthyretin)
D) Hemoglobin level
E) Blood urea nitrogen (BUN)
✓ CORRECT ANSWER: C) Prealbumin (transthyretin)
RATIONALE: Prealbumin has a short half-life of 2-3 days compared to albumin's
half-life of 20 days, making it more sensitive for detecting acute nutritional changes.
It is synthesized in the liver and is an accurate indicator of recent protein status.
Serum albumin reflects long-term nutritional status (weeks to months) and is
affected by liver function and hydration status. Hemoglobin and BUN are not
specific indicators of overall nutritional status. Prealbumin is the gold standard for
assessing recent nutritional changes in clinical practice.

QUESTION 3
,A patient with chronic kidney disease (CKD) stage 4 is on a therapeutic diet.
Which nutrient requires the most careful restriction in this patient's meal
plan?
A) Fat
B) Carbohydrates
C) Potassium
D) Vitamins A and D
E) Fiber
✓ CORRECT ANSWER: C) Potassium
RATIONALE: In advanced CKD, the kidneys cannot effectively excrete potassium,
leading to hyperkalemia, which can cause cardiac arrhythmias and muscle
weakness. Potassium restriction (typically to 2000-3000 mg/day) is critical. While
protein and sodium are also restricted in CKD, potassium management is
particularly important due to the life-threatening cardiac complications of
hyperkalemia. Fat and carbohydrate restriction are not primary concerns for CKD,
though sodium restriction may be important if hypertension is present. Vitamins
require careful consideration, but potassium is the most immediately dangerous if
not managed properly.

QUESTION 4
A 6-month-old infant is being transitioned to solid foods. According to current
feeding guidelines, which food should be introduced first?
A) Egg whites for protein
B) Single-grain iron-fortified cereal
C) Pureed citrus fruits for vitamin C
D) Pureed vegetables to prevent sweet preference
E) Cow's milk mixed with infant cereal
, ✓ CORRECT ANSWER: B) Single-grain iron-fortified cereal
RATIONALE: Iron-fortified single-grain cereals (rice, oatmeal, or barley) are the
recommended first solid foods because they are easily digestible, low in
allergenicity, and help meet the increased iron needs of infants at this
developmental stage. Single grains allow identification of any allergic reactions
before introducing combination foods. Egg whites are allergenic and should be
delayed. Citrus fruits are acidic and may cause digestive upset. Vegetables before
fruits may actually be preferred to avoid establishing sweet preferences. Cow's milk
is not recommended as a beverage before 12 months due to lack of proper
nutrients for infant development.

QUESTION 5
A patient recovering from major surgery is experiencing poor wound healing.
The nurse recognizes that which nutrient is most essential for collagen
synthesis and tissue repair?
A) Vitamin A
B) Vitamin C (Ascorbic Acid)
C) Zinc
D) Selenium
E) Biotin
✓ CORRECT ANSWER: B) Vitamin C (Ascorbic Acid)
RATIONALE: Vitamin C is essential for collagen cross-linking and stabilization,
making it crucial for wound healing. It acts as a cofactor for hydroxylation reactions
necessary for collagen formation. Deficiency leads to poor wound healing and
tissue fragility. While zinc is also important for wound healing and immune
function, vitamin C is specifically required for the structural integrity of the collagen
matrix. Vitamin A supports epithelialization, selenium and biotin contribute to
