A newborn is diagnosed with metatarsus adductus. The parents ask the nurse how this occurred. Which response by the nurse would be most appropriate?

Correct Answer: B

Rationale: Metatarsus adductus is a condition characterized by the inward turning of the front part of the foot. It is often caused by the baby's position in the womb, leading to the foot adopting this position. Choice A is incorrect because metatarsus adductus is primarily related to positioning in utero rather than a genetic defect. Choice C is incorrect as there is an understanding of the common cause of this condition. Choice D is incorrect because metatarsus adductus specifically refers to a foot deformity, not a hip deformity.

Correct Answer: C

Rationale: Delayed physical growth is a common finding in children with symptomatic cardiac malformations. This occurs due to insufficient oxygenation and nutrient supply, which can affect overall growth and development. Mental retardation (Choice A) is not typically associated with symptomatic cardiac malformations. Inherited genetic factors (Choice B) may contribute to the development of cardiac malformations but are not a common finding in affected children. Clubbing of the fingertips (Choice D) is more commonly associated with chronic respiratory or cardiovascular conditions, rather than symptomatic cardiac malformations.

Correct Answer: B

Rationale: The correct way to prevent tinea pedis is by keeping the feet dry, especially between the toes, to decrease the risk of fungal infection. Choice A is incorrect as keeping the feet moist can promote fungal growth. Choice C is incorrect because nylon or synthetic socks can trap moisture, contributing to the growth of fungi. Choice D is incorrect as going barefoot in public, especially in areas like locker rooms, increases the risk of contracting tinea pedis.

Correct Answer: B

Rationale: Vomiting and poor appetite are common symptoms of neuroblastoma, a malignancy that arises from neural crest cells in the adrenal glands or sympathetic nervous system. This tumor can cause abdominal swelling due to its location and size, leading to symptoms like vomiting and decreased appetite. The presence of a maculopapular rash on the palms (Choice A) is not a typical finding associated with neuroblastoma. Irritability and failure to thrive (Choice C) are nonspecific symptoms that can be seen in various conditions but are not specifically indicative of neuroblastoma. Auscultation revealing wheezing with diminished lung sounds (Choice D) may suggest respiratory conditions rather than neuroblastoma.

Correct Answer: B

Rationale: After a cardiac catheterization, the priority nursing care for a 3-year-old child is monitoring the site for bleeding. This is essential to promptly identify and address any signs of bleeding or hematoma formation, which are potential complications of the procedure. Encouraging early ambulation may be beneficial post-procedure but ensuring site integrity takes precedence. Restricting fluids until blood pressure stabilization is not a standard post-catheterization practice, as adequate hydration is crucial for recovery. Comparing the blood pressure of both lower extremities is not a priority immediate nursing action after a cardiac catheterization in a pediatric patient.
