1. A nurse cares for an infant with osteogenesis imperfecta
(OI). Which interventions are appropriate? Select all that
apply.
a. Support the trunk and extremities together when lifting.
b. Use an automated blood pressure cuff for accuracy.
c. Lift the infant by the buttocks rather than the ankles during
diaper changes.
d. Encourage swimming and low-impact play within safe limits.
e. Keep the child immobilized for long periods to prevent
fractures.
,f. Recognize that fractures in various stages of healing can
mimic child abuse.
A, C, D, F
Rationale: In OI, handle gently and support the whole body; use
a MANUAL cuff (automated cuffs over-pressurize fragile arms,
so B is wrong); lift by the buttocks, not the ankles. Promote
weight-bearing/low-impact activity because prolonged
immobilization (E) worsens osteopenia. Multiple healing
fractures can mimic non-accidental trauma.
2. A nurse teaches about pediatric fractures and growth plate
(epiphyseal) injuries. Which statements are accurate? Select all
that apply.
a. Children's bones are softer and more flexible than adults'.
b. About 30% of pediatric fractures involve the growth plate.
c. Growth plate injuries can disrupt future bone growth.
d. Children heal fractures more slowly than adults.
e. Growth plate injuries are classified using the Salter-Harris
system.
f. Early X-rays always clearly reveal growth plate injuries.
A, B, C, E
Rationale: Pediatric bones are soft and flexible; ~30% of
fractures are epiphyseal and can cause limb-length discrepancy
or angular deformity. They are classified by the Salter-Harris
,system. Children heal FASTER than adults (D), and growth
plate injuries may NOT show on early X-rays (F).
3. A nurse performs the Barlow and Ortolani maneuvers on a
newborn. Which finding does the nurse document as a
POSITIVE sign of hip instability or dislocation?
a. A soft, high-pitched click as the hip is moved.
b. A palpable "clunk" as the femoral head moves in or out of the
acetabulum.
c. Symmetric gluteal and thigh skin folds.
d. Equal knee heights when the hips and knees are flexed.
B - a palpable "clunk."
Rationale: The positive Barlow/Ortolani finding is a palpable
"clunk," not a click. A is the trap - a soft, high-pitched click is a
benign, common finding and is NOT considered positive; the
answer is the "clunk." The clunk is the femoral head actually
sliding out of (Barlow) or back into (Ortolani) the acetabulum,
and it is the finding that suggests hip instability or dislocation
and requires further evaluation. C (symmetric skin folds) and D
(equal knee heights) are normal/negative findings. Remember:
click is benign, clunk is the positive sign.
, 4. A nurse teaches the parents of a child with a new fiberglass
cast. Which statements indicate correct understanding? Select all
that apply.
a. "I will lift the wet cast with my palms, not my fingertips."
b. "I can put powder or lotion inside the cast to relieve itching."
c. "I will elevate the casted limb above heart level for the first
day or two."
d. "I will call the provider for a foul odor or drainage stains on
the cast."
e. "I can use cool air, such as a hair dryer on the cool setting, for
itching."
f. "I will report increased swelling, numbness, or increasing
pain."
A, C, D, E, F
Rationale: Lift a wet cast with palms (not fingertips), elevate
above heart level initially, and use cool air for itching. Report
infection signs (foul odor, drainage) and neurovascular changes
(swelling, numbness, increasing pain). NOTHING goes inside
the cast - no powder or lotion (B).
