, PNCB Pediatric Primary Care Exam 2026: 50 Practice Q&A
1. The child at highest risk for having an elevated blood lead level is a:
A. 3-month-old exclusively breastfed infant
B. 6-month-old who lives in a home built after 1970
C. 2-year-old with iron deficiency anemia
D. 2-year-old who is a picky eater
Answer: C
Explanation: The amount of lead absorbed from the gut is increased in children with nutritional
deficiencies such as iron deficiency anemia (IDA). Iron deficiency anemia is often a comorbidity
of lead poisoning. The hand-to-mouth behavior of infants and young children increases their lead
exposure. However, living in a home built after 1970 reduces the risk since residential paint used
in that era should not have been lead-based.
2. Which laboratory assessment is the BEST indicator of vitamin D deficiency?
A. 25(OH)-D (cholecalciferol)
B. 1,25(OH)2-D (calcitriol)
C. PTH (parathyroid hormone)
D. Serum calcium
Answer: A
Explanation: The best diagnostic study for vitamin D deficiency is the level of 25(OH)-D
(cholecalciferol). 1,25(OH)2-D (calcitriol) is the active metabolite but has a short half-life and is
not a reliable indicator of vitamin D status. PTH and serum calcium are not specific for vitamin
D deficiency.
3. In a 2-month-old with visible rib fractures on radiograph, the NEXT most critical evaluation to
obtain is a:
A. CT scan of the head
B. Long bone series
C. Coagulation profile
D. Retinal ophthalmologic exam
, Answer: A
Explanation: Posterior rib fractures are highly suggestive of non-accidental trauma, such as
shaken baby syndrome. Subdural and subarachnoid hemorrhages are common intracranial
injuries in such cases. A head CT is critical to evaluate for acute brain injury.
4. The MOST common barrier related to transitioning health care for an adolescent with special
needs or chronic illness is:
A. Finding an adult health care provider for transition
B. Resistance of the family and adolescent to transition of care
C. Lack of health care provider time to plan for transition of care
D. Difficulty in talking with patients about transitioning care
Answer: A
Explanation: Finding an adult health care provider who is qualified to care for young adults
with special health care needs is the most commonly perceived barrier to successful transition, as
identified by families, adolescents, and providers.
5. A toddler is unable to use the right arm normally after the caregiver pulled her arm to prevent
the child from falling. Which finding would confirm the diagnosis of subluxation of the radial
head?
A. Severe swelling and bruising of the elbow
B. Elbow flexed with pronated forearm
C. Point tenderness at ulnar aspect of elbow
D. Obvious deformity of the forearm
Answer: B
Explanation: Subluxation of the radial head (nursemaid’s elbow) typically presents with the
elbow flexed and forearm pronated. There is usually no swelling or deformity. The history of
traction injury is classic.
6. Education for caregivers whose child has sickle cell disease should include that the majority of
pain crises are triggered by which of the following?
A. No identifying cause
