A nurse is reinforcing teaching about car safety with the parents of a preschool-age child.
Which of the following findings indicates the correct use of a booster seat?
The lap belt fits snugly over the child's abdomen.
The lap belt fits low across the child's hips.
The child is in the front seat using a shoulder-only automatic belt.
The shoulder strap crosses just below the child's chin.
The Correct Answer is B
Choice A rationale
The lap belt fitting snugly over the child's abdomen increases the risk of abdominal injury during a crash.
Choice B rationale
The lap belt fitting low across the child's hips distributes force over stronger bony structures, reducing injury risk.
Choice C rationale
Placing a child in the front seat with a shoulder-only automatic belt does not provide proper restraint and increases injury risk.
Choice D rationale
The shoulder strap crossing just below the child's chin indicates improper fit, posing a risk to the neck in a crash.

Correct Answer is ["3.8"]
Explanation
Step 1: lb ÷ (2.2 lb/kg) = 10 kg.
Step 2:.5 mg/kg/day × 10 kg = 15 mg/day.
Step 3: mg/day ÷ 4 doses/day = 3.75 mg/dose.
Step 4:.75 mg ÷ 1 mg/mL = 3.75 mL per dose.
The calculated answer is 3.8 mL (rounded to the nearest tenth).
Correct Answer is D
Explanation
Choice A rationale
Boys are generally screened for scoliosis at a later age than girls due to different growth patterns and timelines in puberty. Girls typically go through growth spurts earlier, which can reveal scoliosis sooner.
Choice B rationale
Scoliosis is not associated with childhood trauma. It's primarily idiopathic, meaning its cause is unknown, though genetics and growth factors are considered.
Choice C rationale
Children with scoliosis often do not report back pain. The condition is usually detected through physical exams or screenings rather than symptoms like pain.
Choice D rationale
The Adam's forward bend test is a common method for screening scoliosis, which involves the child bending forward at the waist with arms hanging down. This position highlights any abnormal curvature of the spine.
