After surgical repair of a cleft palate, what should be used to prevent injury to the suture line?

Correct Answer: C

Rationale: The correct answer is C: Syringe. Using a syringe helps in feeding without causing injury to the suture line after cleft palate repair because it avoids direct contact with the suture area. Straws and spoons can potentially put pressure on the suture line, leading to injury. Cups may not provide the necessary control to prevent contact with the suture line, unlike a syringe.

Correct Answer: C

Rationale: The correct answer is C: Absence of parasympathetic ganglion cells in a portion of the colon. Hirschsprung disease is a congenital condition characterized by the absence of nerve cells (ganglia) in parts of the colon. This absence leads to a lack of peristalsis in the affected segment, resulting in severe constipation and bowel obstruction. Choices A, B, and D are incorrect. Choice A describes symptoms of diarrhea rather than a causative factor of Hirschsprung disease. Excessive peristaltic movement (choice B) is not a causative factor but rather the opposite, as Hirschsprung disease is associated with reduced peristalsis. Choice D, which refers to intussusception, is a different condition unrelated to Hirschsprung disease.

Correct Answer: A

Rationale: The Pavlik harness is designed to position a child's femurs in abduction for developmental hip dysplasia. Abduction helps align the hip joint correctly and promotes proper development in cases of hip dysplasia. Adduction (choice B) brings the legs closer to the midline, which is not the desired position in this condition. Flexion (choice C) refers to bending at a joint, while extension (choice D) is the opposite of flexion. However, in the case of developmental hip dysplasia, abduction is crucial for the Pavlik harness to work effectively.

Correct Answer: B

Rationale: Children with a history of severe allergic reactions should receive inactivated vaccines because they do not contain live pathogens. Live attenuated vaccines (choice A) contain weakened live pathogens and can potentially trigger an allergic reaction in sensitive individuals. Subunit vaccines (choice C) and recombinant vaccines (choice D) may contain components that could still trigger an allergic response in individuals with a history of severe allergies. Inactivated vaccines are the safest choice for individuals with a history of severe allergic reactions as they do not pose a risk of causing an allergic reaction due to the absence of live pathogens.

Correct Answer: B

Rationale: The correct first step in managing a child with a suspected head injury is to assess the child's level of consciousness. This assessment is crucial as it helps determine the severity of the injury and guides further management. Administering pain medication (Choice A) should not be done before assessing the level of consciousness. Performing a CT scan (Choice C) may be necessary but is not the initial step. Monitoring for seizures (Choice D) is important but comes after assessing the child's level of consciousness.
