A nurse is preparing to percuss an adolescent's chest and abdomen. Which of the following areas should the nurse expect to hear a dull sound? (You will find hot spots to select in the artwork below. Select only the hot spot that corresponds to your answer.)

A. The FLACC pain rating scale is appropriate for infants and young children, assessing pain based on Face, Legs, Activity, Cry, and Consolability, making it suitable for a 5-month-old infant.
B. The COMFORT pain rating scale is generally used for children who are unable to communicate their pain, typically in older children or adolescents, and is less suitable for this age group.
C. The FACES pain rating scale is designed for children aged 3 and older who can identify facial expressions but is not appropriate for a 5-month-old infant.
D. The CRIES pain rating scale is also used for infants but is more specific to neonates (0-6 months) and measures crying, oxygen requirement, increased vital signs, and facial expressions, making it less applicable than the FLACC scale for this specific postoperative context.

Rationale:

A) Placing the child in a forward-facing car seat before the appropriate age and size increases the risk of injury.

B) Placing the child in the front seat, even in a rear-facing car seat, is not recommended due to the risk of airbag deployment.

C) Booster seats are used for older children who have outgrown their forward-facing car seats, but are not yet big enough to use the seat belt properly. Booster seats should be used until the child is at least 4 feet 9 inches tall and between 8 and 12 years old.

D) Placing the child in a rear-facing car seat until age 2 is recommended by safety guidelines to provide optimal protection for the child's head, neck, and spine.
