1. What is an important consideration when administering medications to a child with a history of chronic renal failure?

A. Increased frequency of medication administration
B. Adjustments in dosage due to altered drug metabolism
C. Avoidance of all medications
D. Use of only intravenous medications

Correct answer: B

Rationale: When administering medications to a child with chronic renal failure, it is crucial to consider adjustments in dosage due to altered drug metabolism. Children with chronic renal failure may have impaired drug excretion, leading to potential drug accumulation and toxicity. Increasing the frequency of medication administration (choice A) may not address the altered drug metabolism issue and could increase the risk of adverse effects. Avoiding all medications (choice C) is not practical or safe as some medications may be necessary for the child's health. Using only intravenous medications (choice D) is not always required and may not be the best route of administration for all medications needed.

2. Approximately how many grams does a normal half-cup vegetable portion weigh?

A. 5 grams
B. 50 grams
C. 100 grams
D. 150 grams

Correct answer: C

Rationale: A normal half-cup vegetable portion usually weighs around 100 grams. This weight is a standard measurement for a half-cup serving of vegetables, making choice C the correct answer. Choices A, B, and D are incorrect as they do not align with the typical weight of a half-cup vegetable portion.

3. What is the term for the study of how diet affects gene expression?

A. Epigenetics
B. Nutrigenomics
C. Genomics
D. Genetics

Correct answer: B

Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.

4. Parents of a 6-month-old child, diagnosed with iron deficiency anemia, ask why it was not diagnosed earlier. What should the nurse say?

A. Are you sure your child has iron deficiency anemia?
B. Maternal stores of iron are depleted at about 6 months.
C. This anemia is caused by blood loss.
D. The child may not have had it for a long time.

Correct answer: B

Rationale: The correct answer is B: 'Maternal stores of iron are depleted at about 6 months.' Iron deficiency anemia becomes apparent around 6 months of age when the infant's iron stores, primarily received from the mother during pregnancy, are depleted. This timing coincides with the introduction of solid foods, which may lack sufficient iron. Choices A, C, and D are incorrect because they do not address the specific reason why iron deficiency anemia is typically diagnosed around 6 months of age.

5. What is a common sign of developmental dysplasia of the hip (DDH) in infants?

A. Dislocated patella
B. Limited abduction of the hip
C. Swelling of the knee
D. Hyperextension of the leg

Correct answer: B

Rationale: Limited abduction of the hip is a common sign of developmental dysplasia of the hip in infants. It indicates possible hip dislocation or instability, making it a key clinical manifestation to assess for DDH. Dislocated patella (Choice A) is not typically associated with DDH. Swelling of the knee (Choice C) and hyperextension of the leg (Choice D) are not specific signs linked to DDH in infants, further supporting why they are incorrect choices.
