Correct Answer: B

Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL to prevent overdistension and potential harm. Choice A (100 to 150 mL) is too low and may not be effective in achieving the desired outcome. Choices C (255 to 360 mL) and D (365 to 500 mL) exceed the safe range for a 2-year-old child and can lead to overdistension, electrolyte imbalance, or other complications. Therefore, the correct answer is B.

Correct Answer: D

Rationale: The correct answer is D: Side-lying. After surgery using steel bar placement to correct pectus excavatum, the nurse should instruct the parents to avoid placing the child in a side-lying position. This position should be avoided to prevent displacement of the steel bar. Choices A, B, and C are incorrect. Semi-Fowler, Supine, and High Fowler positions are generally safe and commonly used in postoperative care, but in this specific case, side-lying should be avoided to ensure the effectiveness of the surgical correction.

Correct Answer: B

Rationale: During a check-up for a child with eczema, assessing compliance with treatment regimens is a key nursing intervention. This helps ensure that the child is following the prescribed treatment plan effectively, which is crucial in managing eczema and preventing flare-ups. Changing a bandage on a cut is not directly related to managing eczema. Discussing systemic corticosteroid therapy may be part of the visit, but assessing compliance is more immediate and essential. Assessing the child's fluid volume is important for overall health assessment but not specifically related to managing eczema.

Correct Answer: D

Rationale: Correct answer: When feeding a newborn with choanal atresia, the nurse should anticipate that the infant may take only part of the feeding. This behavior is due to the condition causing difficulty in breathing through the nose while feeding, prompting the infant to pause for air. Choice A, 'Chokes on the feeding,' is incorrect as it does not specifically relate to the feeding behavior expected in choanal atresia. Choice B, 'Has difficulty swallowing,' is also incorrect because the issue in choanal atresia is primarily related to breathing rather than swallowing. Choice C, 'Does not appear to be hungry,' is not the typical behavior seen in infants with choanal atresia; they may still display hunger cues but struggle with feeding due to the condition.

Correct Answer: B

Rationale: Choice B is the correct answer because it accurately states that White, non-Hispanic children are more likely to be in very good or excellent health compared to African American and Hispanic children. This reflects a disparity in health outcomes among different racial groups. Choices A, C, and D are incorrect. Choice A is unrelated to the impact of common barriers to health care on families. Choice C talks about overweight children but does not address access to health care. Choice D discusses the impact of the overall health care plan on working families but does not specifically address the disparity in health status among different racial groups.
