Correct Answer: C

Rationale: Low-set ears with lobe creases are often associated with genetic disorders, such as Down syndrome, and can indicate underlying chromosomal abnormalities. This physical characteristic is a common feature seen in various genetic syndromes. The other choices, including feeding problems, weight and height measurements, and motor skills, are not typically specific indicators of genetic disorders in the absence of other associated features.

Correct Answer: A

Rationale: Epicanthal folds are a common physical feature seen in individuals with Down syndrome. These are folds of skin that cover the inner corners of the eyes. Webbed neck (Choice B) is associated with Turner syndrome, not Down syndrome. Enlarged head (Choice C) is not a typical physical characteristic of Down syndrome. Polydactyly (Choice D) is the presence of extra fingers or toes, which is not specifically related to Down syndrome.

Correct Answer: A

Rationale: The most important nursing intervention for a child with leukemia receiving chemotherapy is to monitor for signs of infection. Chemotherapy suppresses the immune system, putting the child at a higher risk of developing infections. Early detection and prompt treatment of infections are crucial to prevent complications and improve outcomes. Monitoring for signs of bleeding (choice B), dehydration (choice C), and pain (choice D) are also important aspects of care, but in this scenario, the priority is to prevent and manage infections due to the compromised immune system.

Correct Answer: B

Rationale: During a vaso-occlusive crisis in sickle cell anemia, the priority nursing intervention is administering pain medication to alleviate the severe pain associated with the crisis. While administering oxygen can help improve oxygenation, pain relief is crucial in managing the crisis. Monitoring fluid intake is important in sickle cell anemia but is not the most immediate intervention during a vaso-occlusive crisis. Encouraging physical activity is contraindicated during a vaso-occlusive crisis as it can exacerbate pain and complications.

Correct Answer: B

Rationale: The correct answer is B: Paroxysmal abdominal pain. Colic in infants is characterized by paroxysmal abdominal pain, leading to excessive crying and fussiness. It is not caused by inadequate peristalsis (Choice A), an allergic response to certain proteins in milk (Choice C), or a protective mechanism designed to eliminate foreign proteins (Choice D). Understanding that colic is primarily associated with abdominal pain helps healthcare providers provide appropriate care and support to parents dealing with colicky infants.
