Correct Answer: D

Rationale: Pegs and pounding boards are the most suitable choice for toddlers to express their emotions constructively. These materials provide a safe and acceptable way for toddlers to release anger and frustration through physical activity. Options A, B, and C may not be as effective or safe for toddlers dealing with temper tantrums. A ball and bat may encourage aggressive behavior rather than constructive expression. A wad of clay might not be ideal for channeling anger, and a punching bag can potentially promote violent behavior, which is not appropriate for toddlers.

Correct Answer: B

Rationale: The priority nursing care after a cardiac catheterization in a 3-year-old is to monitor the site for bleeding. This is essential to promptly detect and manage any potential complications, such as hematoma or hemorrhage. Encouraging early ambulation, as mentioned in choice A, may not be safe immediately post-procedure and should be guided by the healthcare provider's instructions. Restricting fluids until blood pressure is stabilized, as in choice C, is not typically necessary after a cardiac catheterization. Comparing blood pressure in both lower extremities, as in choice D, is not the priority immediate nursing care following this procedure.

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: Metatarsus adductus is a condition where the front part of the foot is turned inward. It is often caused by the baby's position in the womb, leading to pressure on the foot during fetal development. Choice A is incorrect as metatarsus adductus is not primarily caused by a genetic defect in the bones. Choice C is incorrect as the cause of metatarsus adductus is known to be related to intrauterine positioning. Choice D is incorrect as metatarsus adductus specifically pertains to the foot and not the hip.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial in managing asthma as certain foods can trigger symptoms or exacerbate the condition. By evaluating the child's diet, the nurse can identify potential triggers, ensure the child receives proper nutrition, and help manage symptoms effectively. Assessing sleep patterns, academic performance, or behavior at home, while important in a holistic assessment, are not as directly related to managing asthma symptoms as dietary intake.
