A nurse is about to administer a vaccination to a 4 year old. What developmental response to this painful procedure is MOST likely for a preschool aged child.
The child withdraws and attempts to hide because they think the pain is a form of punishment.
The child denies being scared about pain in an attempt to seem brave, and withdraws to a game on mom's phone.
The child makes facial expressions such as brow contracting and chin quivering in anticipation of the pain.
The child kicks, hits and cries due to lack of control over the situation.
The Correct Answer is C
Rationale:
A. The child withdraws and attempts to hide because they think the pain is a form of punishment: This is more typical of toddlers who have limited understanding and may associate pain with punishment, rather than preschoolers who have a better grasp of cause and effect.
B. The child denies being scared about pain in an attempt to seem brave, and withdraws to a game on mom's phone: While distraction techniques are effective, preschoolers are more likely to show visible signs of distress rather than denying fear completely, as their emotional expression is more open.
C. The child makes facial expressions such as brow contracting and chin quivering in anticipation of the pain: Preschool-aged children often express fear and anxiety about painful procedures through facial cues and body language, showing clear anticipation and emotional response.
D. The child kicks, hits and cries due to lack of control over the situation: This aggressive and oppositional behavior is more characteristic of toddlers or children with less developed coping skills, rather than preschoolers who generally have more emotional regulation.

Correct Answer is D
Explanation
Rationale:
A. "The blood supply to the bone is disrupted.": While some fractures can disrupt blood supply, epiphyseal plate fractures primarily threaten the growth plate itself, and vascular disruption is not the main concern with these injuries.
B. "The younger the child, the longer the healing process will take.": Younger children generally heal faster due to better bone remodeling capacity and more active growth plates, so healing time tends to be shorter, not longer.
C. "Bone marrow can be lost through the fracture.": Bone marrow loss is uncommon in epiphyseal plate fractures and is more relevant in open fractures or those involving severe bone trauma.
D. "Normal bone growth can be affected.": Damage to the epiphyseal (growth) plate can impair normal bone growth, potentially leading to limb length discrepancies or angular deformities, making this a crucial point for parents to understand.
Correct Answer is A
Explanation
Rationale:
- Convert weight to kg:
60 lb ÷ 2.2
= 27.27 kg
- Calculate safe dose range per dose:
Minimum = 10 mg/kg × 27.27 kg
= 272.7 mg
Maximum = 15 mg/kg × 27.27 kg
= 409 mg
Prescribed dose is 400 mg, which falls within the safe range of 273 mg to 409 mg per dose. The dose is safe based on weight.
