Correct Answer: B

Rationale: It is recommended that a child should visit the dentist within the next few months after turning two years old. This allows for early dental check-ups to monitor oral health, detect any issues early on, and establish a good oral hygiene routine. Choice A ('Before starting school') is not as specific and may delay the child's first dental visit. Choice C ('When the first deciduous teeth are lost') is too late for the first dental visit, as preventive care should start earlier. Choice D ('At the next dental visit of a family member') is not ideal as the child's dental needs should be addressed independently of family members' visits.

Correct Answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.

Correct Answer: C

Rationale: The priority nursing action after corrective surgery for hypertrophic pyloric stenosis (HPS) is to assess the IV site for infiltration. This is crucial as it ensures proper fluid administration and prevents complications such as phlebitis or infiltration-related tissue damage. Applying restraints (Choice A) would not be appropriate in this situation as it is not related to the immediate post-operative care of an infant with an IV infusion. Administering a mild sedative (Choice B) is not indicated as the primary concern post-surgery is monitoring the IV site and the infant's response to the surgery. Attaching the nasogastric tube to wall suction (Choice D) is not the priority at this time, as assessing the IV site takes precedence to prevent potential complications.

Correct Answer: B

Rationale: Seizures are a common complication in children with high fever and altered mental status, indicating a risk of febrile seizures. While vomiting can occur with altered mental status, seizures are of higher concern due to the association with febrile illnesses in children. Combativeness may be a concern in some altered mental status cases but is not as common as seizures. Respiratory distress, although important, is not the primary concern in this scenario given the symptoms presented.

Correct Answer: B

Rationale: The correct answer is to monitor for signs of dehydration. After treatment for dehydration, it is crucial to educate caregivers about recognizing early signs of dehydration to prevent its recurrence. Monitoring for dehydration ensures that appropriate measures can be taken promptly if signs reappear. Choices A, C, and D are incorrect because infection, hypovolemia, and malnutrition, while important considerations in healthcare, are not the primary focus after treating dehydration in a 3-year-old child.
