However, it is normally elevated during infancy. At which age does AFP physiologically fall to normal adult level?
- A. three month
- B. eight month
- C. one year
- D. three year

Which principle does not follow neuromaturational theory?
- A. The sequence and rate of motor development are consistent among infants
- B. Movement emerges from an interaction and cooperation of many systems
- C. Movement progresses from primitive reflexes to voluntary control
- D. Low-level skills are prerequisites for certain high-level skills
Correct Answer: B
Rationale: Neuromaturational theory emphasizes that motor development progresses in a predictable sequence and rate, starting from primitive reflexes to voluntary control. It also states that low-level skills are foundational for higher-level skills. However, the theory does not support the idea that movement solely emerges from an interaction and cooperation of many systems, as it focuses more on the hierarchical development of motor skills.
A school-age child is 2 hours postoperative following a tonsillectomy. Which of the following actions should the nurse include in the plan of care?
- A. Place a heating pad at the surgical site.
- B. Encourage the child to cough every 2 hours.
- C. Administer analgesics to the child on a regular schedule.
- D. Apply an ice collar to the child's neck.
Correct Answer: D
Rationale: After a tonsillectomy, applying an ice collar to the child's neck helps decrease pain and swelling. Heat should be avoided as it can increase bleeding. Encouraging coughing may increase the risk of bleeding. Administering analgesics on a regular schedule is essential for pain management, but the immediate postoperative period may require additional interventions like ice collar application.
