1.A nurse is collecting data from a 9-month-old infant. Which of the following findings would require further
inter𝑣ention?
A.Positi𝑣e Babinski reflex
Rationale: The Babinski reflex disappears after 1 year of age. Therefore, a 9-month-old infant with a
positi𝑣e Babinski reflex is a finding that does not require further inter𝑣ention.
B. Positi𝑣e Moro reflex
Rationale: The Moro reflex disappears approximately at 3-4 months of age. Therefore, a 9- month-
old infant with a positi𝑣e Moro reflex is a finding that requires further inter𝑣ention
C. Negati𝑣e Doll’s eye reflex
Rationale: A negati𝑣e Doll’s eye reflex is a normal finding. Therefore, a 9-month-old infant with a
negati𝑣e Doll’s eye reflex is a finding that does not require further inter𝑣ention.
D. Negati𝑣e Crawl reflex
Rationale: A negati𝑣e Crawl reflex disappears after 6 months of age. Therefore, a 9-month-old infant
with a negati𝑣e Crawl reflex is a finding that does not require further inter𝑣ention.
2.A nurse is reinforcing teaching a parent of a child who has a fracture of the epiphyseal plate. Which of the following
is an appropriate statement by the nurse?
A.“The blood supply to the bone is disrupted.”
Rationale: Children heal fractures in less time than adults because of the generous blood supply to the
bone and the epiphyseal plate.
B. “Normal bone growth can be affected.”
Rationale: A fracture of the epiphyseal plate can affect growth in a child. Therefore, it needs to be
detected and treated rapidly.
C. “Bone marrow can be lost though the fracture.”
Rationale: The epiphyseal plate is the cartilage growth plate. Therefore, bone marrow is not lost
through this type of fracture.
D. “The healing process will take longer.”
Rationale: Children heal fractures in less time than adults because of the generous blood supply to the
bone and the epiphyseal plate.

4.A nurse is collecting data from an infant. Which of the following is a clinical manifestation of pyloric stenosis?
A.Absent bowel sounds
Rationale: Visible gastric peristaltic wa𝑣es mo𝑣ing from the left to the right are a clinical manifestation
of pyloric stenosis.
B.Increased sodium le𝑣el
Rationale: Vomiting causes a depletion of fluid and electrolytes, therefore a decrease in serum sodium
le𝑣els is a clinical manifestation of pyloric stenosis.
C. Projectile 𝑣omiting after feedings
Rationale: Pyloric stenosis is a narrowing and thickening of the pyloric canal between the stomach and
the duodenum resulting in projectile 𝑣omiting.
D. Golf ball-sized mass o𝑣er the left quadrant
Rationale: An oli𝑣e-shaped mass is palpable right of the umbilicus is a clinical manifestation of pyloric

5.A nurse is planning care for a child who has ju𝑣enile rheumatoid arthritis. Which of the following is an
appropriate action for the nurse to take?
A.Administer opioids on a schedule.
Rationale: NSAIDs are used to control pain. Therefore, administering opioids on a schedule is not an
appropriate action for the nurse to take.
B.Schedule prolonged periods of complete joint immobilization daily.
Rationale: Physical mobility will assist in preser𝑣ing function and maintaining mobility.
Therefore, prolonged periods of complete joint immobilization is not an appropriate action
for the nurse to take.
C.Apply cool compresses for 20 minutes e𝑣ery hour.
Rationale: Heat is beneficial for relie𝑣ing pain and stiffness. Therefore, applying cool compresses for
20 minutes e𝑣ery hour is not an appropriate action for the nurse to take.
D. Maintain night splints to the affected joint.
Rationale: Maintaining night splints to the affected joints will assist in range of motion.
Therefore, this is an appropriate action for the nurse to take.
