Lifespan Nutrition, and High-Yield Review with Detailed Answer
Rationales
Section 1: Nutrition Across the Lifespan (Pregnancy, Infants, Geriatrics)
1. A nurse is providing dietary teaching to a client who is at 10 weeks of
gestation. Which of the following nutrients should the nurse prioritize to
prevent neural tube defects?
• A. Calcium
• B. Iron
• C. Folic Acid
• D. Vitamin D
Answer: C. Folic Acid
Rationale: Folic acid (vitamin B9) is crucial for proper neural tube closure during
the first trimester. A deficiency can lead to spina bifida or anencephaly.
2. A nurse is teaching the parent of a 6-month-old infant about introducing solid
foods. Which of the following foods should the nurse recommend introducing
first?
• A. Strained fruits
• B. Iron-fortified rice cereal
• C. Egg whites
• D. Cow's milk
Answer: B. Iron-fortified rice cereal
Rationale: Iron-fortified single-grain cereal is recommended as the first solid food
because infants' iron stores begin to deplete around 6 months. Cow's milk should
not be introduced until 12 months.
3. A nurse is assessing an older adult client for signs of malnutrition. Which of
the following findings is the priority for the nurse to report?
, • A. BMI of 20
• B. Prealbumin 10 mg/dL
• C. Hemoglobin 14 g/dL
• D. Potassium 4.2 mEq/L
Answer: B. Prealbumin 10 mg/dL
Rationale: Prealbumin is a sensitive indicator of recent nutritional status; a level
of 10 mg/dL indicates severe protein-calorie malnutrition. The other values are
within normal limits.
4. A nurse is teaching a parent about appropriate snack choices for a 9-month-
old infant. Which of the following food choices should the nurse recommend?
• A. Raw carrot sticks
• B. Graham crackers
• C. Skim milk
• D. Honey
Answer: B. Graham crackers
Rationale: Graham crackers dissolve easily and pose a low choking risk. Raw
vegetables are a choking hazard, skim milk lacks essential fat, and honey carries a
risk of infant botulism before 12 months.
5. A nurse is assessing an older adult client for risk factors of malnutrition.
Which finding is the greatest risk factor?
• A. Taking multiple medications (polypharmacy)
• B. Having dentures that fit well
• C. Living with family members
• D. Participating in a community meal program
Answer: A. Taking multiple medications (polypharmacy)
Rationale: Polypharmacy can lead to decreased appetite, drug-nutrient
interactions, and altered taste, all of which significantly increase malnutrition risk.
,6. A nurse is providing dietary teaching to a client who is pregnant. Which of the
following statements by the client indicates an understanding of the teaching?
• A. "I should increase my calcium intake to 1,500 mg/day."
• B. "I need to double my caloric intake during the first trimester."
• C. "I should increase my iron intake to prevent anemia."
• D. "I can continue to drink alcohol in moderation."
Answer: C. "I should increase my iron intake to prevent anemia."
Rationale: Iron needs increase during pregnancy to support maternal blood
volume expansion and fetal needs. Calcium recommendation is 1,000 mg/day
(not 1,500 mg), caloric needs increase by about 340-450 kcal/day in the
second/third trimesters (not doubled), and alcohol should be avoided entirely.
7. A nurse is caring for a client who is breastfeeding. Which of the following
nutrients should the nurse recommend increasing in the client's diet?
• A. Vitamin C
• B. Vitamin D
• C. Vitamin K
• D. Vitamin E
Answer: B. Vitamin D
Rationale: Breastfeeding mothers need adequate vitamin D to ensure sufficient
levels in breast milk. Supplementation of 400 IU/day is often recommended for
breastfed infants as well.
8. A nurse is providing education to the parents of a toddler about appropriate
portion sizes. Which of the following statements by the parent indicates
understanding?
• A. "My child should eat 1 tablespoon of each food per year of age."
• B. "My child should eat the same portion size as an adult."
• C. "My child should eat only when hungry, regardless of portion size."
• D. "My child should finish everything on the plate."
, Answer: A. "My child should eat 1 tablespoon of each food per year of age."
Rationale: A general guideline for toddler portion sizes is 1 tablespoon of each
food per year of age. This helps prevent overfeeding and respects the child's
appetite.
9. A nurse is assessing a school-age child for signs of iron deficiency anemia.
Which of the following findings should the nurse expect?
• A. Increased energy level
• B. Pale conjunctiva
• C. Hypertension
• D. Hyperactivity
Answer: B. Pale conjunctiva
Rationale: Pale conjunctiva and mucous membranes are classic signs of iron
deficiency anemia due to decreased hemoglobin. Fatigue and pallor are expected,
not increased energy or hyperactivity.
10. A nurse is teaching a group of older adults about nutrition. Which of the
following statements should the nurse include?
• A. "Caloric needs increase with age."
• B. "Protein needs decrease with age."
• C. "Fiber intake should be increased to prevent constipation."
• D. "Fluid intake should be limited to prevent edema."
Answer: C. "Fiber intake should be increased to prevent constipation."
Rationale: Older adults often experience decreased GI motility; increased fiber
and fluid intake help prevent constipation. Caloric needs typically decrease,
protein needs may increase, and fluid should not be limited unless medically
indicated.
