Answer to Question 1

B
Feedback
A Positive Ortolani's sign yields a clunking sensation and indicates a dislocated
femoral head moving into the acetabulum.
B Asymmetric thigh and gluteal creases may indicate potential dislocation of the
hip.
C During a positive Barlow test, the examiner can feel the femoral head move out
of acetabulum.
D If the hip is dislocated, the knee on the affected side will be lower.

Answer to Question 2

D
Feedback
A The child with lactose intolerance is not at risk for hyperkalemia.
B Lactose intolerance does not affect glucose metabolism.
C Hyperglycemia does not result from ingestion of a lactose-free diet.
D The child between 1 and 10 years requires a minimum of 800 mg of calcium
daily. Because high-calcium dairy products containing lactose are restricted from
the child's diet, alternative sources such as egg yolk, green leafy vegetables,
dried beans, and cauliflower must be provided to prevent hypocalcemia.
