FNP 2 EXAM 3 2026 FINAL PAPER REVIEW
QUESTIONS ANSWERS BUNDLED PRACTICE
COLLECTION
◉ Why is a special diet necessary for life in a 1-month-old diagnosed
with phenylketonuria (PKU)?
Answer: Tx: balanced restriction of phenylalanine
The diet is supplemented with a medically modified formula, free of
phenylalanine. Over the child's first few years of life, parents are
educated on the phenylalanine content of foods; the child's
phenylalanine level is frequently monitored, and a phenylalanine
"allowance" is established based on the child's dietary tolerance. The
current recommendation is a "diet for life" to prevent long-term
cognitive and neurologic sequelae
◉ What is PKU
Answer: Inability to change phenylalanine to tyrosine
Results in mental retardation and irreversible brain damage
◉ What characterizes a Salter-Harris Type II fracture in a school-age
child with a fractured wrist?
,Answer: Most common type of growth plate fracture, similar to type
I except that the metaphyseal fragment is present on the
compression side of the fracture
◉ Salter Harris Fracture Type I
Answer: Involves a fracture through the zone of hypertrophic cells of
the physis with no fracture of the surrounding bone
◉ What does a positive Barlow maneuver indicate during a hip
screening for developmental dysplasia?
Answer: That the hip joint can be easily dislocated or moved out of
socket, indicating hip instability that could lead to hip dislocation
◉ What is the appropriate management for a 3-year-old who refuses
to use the right arm after being swung by both arms?
Answer: What is the appropriate management for a 3-year-old who
refuses to use the right arm after being swung by both arms?
Techniques to Reduce Radial Head: Supination and flexion
Hyperpronation and extension
Caution: Do not attempt either procedure if there is epitrochlear
tenderness, as this may indicate a more serious injury (e.g.,
fracture).
◉ How is a closed fracture of the right clavicle managed in a school-
age child?
,Answer: Sling Immobilization: Provides comfort and support for the
affected extremity. Generally, can be discontinued at 3 to 4 weeks.
Figure-Eight Clavicular Brace: Used if displacement results in
decreased shaft length. May be uncomfortable to wear. Effectiveness
is questionable.
Protection Duration: Generally sufficient for 4 to 5 weeks. Union
typically requires about 4 weeks of healing.
Pain Management for Older Children: May require analgesics or a
nonsteroidal anti-inflammatory drug (NSAID).
5. Surgical Intervention:
Uncommon for clavicular fractures.
May be necessary in cases of: Open fractures Neurovascular
compromise Multiple traumas Rib cage fractures Fractures with
greater than 100% displacement and severe skin tenting.
◉ What is the recommended treatment for a young adolescent with
chest pain associated with coughing and lifting, but no history of
injury?
Answer: Diagnosis: costochondritis or sternochondritis =
Inflammation of the costochondral cartilage in the anterior chest
wall
Benign and self-limiting; does not involve the CV system
Management: Rest, NSAIDs, Ice, and Gentle stretching
, ◉ What is the correct treatment for a 6-month-old infant with
positive Ortolani and Barlow signs?
Answer: Infants Aged 6 to 18 Months with Dislocated Hip: Likely
require either: Closed manipulation Open reduction
Adductor Tenotomy: Gentle reduction helps prevent osteonecrosis
of the femoral head.
Post-Reduction Care: A hip spica cast is applied to: Maintain the hip
in more than 90 degrees of flexion. Avoid excessive internal or
external rotation.
◉ What is the most important initial management for an overweight
14-year-old boy with a unilateral limp and hip pain?
Answer: 1. Refer immediately to the emergency department to see
an orthopedic surgeon.
2. Place child on crutches or in a wheelchair. Non-weight bearing
must be emphasized to prevent further slippage. Once the diagnosis
has been made, the child should immediately be admitted to the
hospital and placed on bed rest
◉ What is the appropriate action for a 12-month-old with bilateral
internal tibial torsion and asymmetric bowing of the legs?
Answer: Typically
1. No treatment; self-resolves
2. Assessment q 3-6 months
