Correct Answer: C

Rationale: At 18 months of age, needing assistance to climb stairs upright is considered normal behavior for a toddler. Crawling upstairs is a different motor skill and does not necessarily correlate with the ability to climb stairs. The child is still developing gross motor skills, and climbing stairs upright typically requires more coordination and strength, which may not be fully developed at this age. Choices A, B, and D are not relevant in this scenario as the observed behavior is within the expected range of development for an 18-month-old child.

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: C

Rationale: Low-set ears with lobe creases are often associated with genetic disorders and can indicate underlying chromosomal abnormalities. This physical characteristic is known to be a common sign in various syndromes like Down syndrome. Choices A, B, and D are not directly linked to genetic disorders. Feeding problems and specific weight/height measurements are more general indicators of growth and development, while the ability to hop on one foot but not skip is a developmental milestone assessment that does not specifically point towards a genetic disorder.

Correct Answer: C

Rationale: The correct preoperative intervention for a child with pyloric stenosis is to monitor for signs of dehydration. Pyloric stenosis involves the obstruction of the pyloric sphincter, leading to projectile vomiting, which can result in dehydration and electrolyte imbalances. Monitoring for signs of dehydration is crucial to assess the child's fluid status and prevent complications. Administering intravenous fluids, although important in managing dehydration, is not typically a preoperative intervention but rather a treatment during or after surgery. Monitoring for signs of infection and pain may also be important but are not the priority preoperative interventions in a child with pyloric stenosis.

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.
