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.

that TSS is commonly associated with which of the following?
A. High-absorbency tampons

Rationale: Mosquito bites are not associated with TSS.
C. International travel
Rationale: International travel is not associated with TSS.

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.

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.

finding? (Select all that apply.)
A. Symptoms are continuous throughout the day.
B. Daytime symptoms occur more than twice a week.
C. Nighttime symptoms occur approximately twice a month.
D. Minor limitations occur with normal activity.
E. Peak expiratory flow (PEF) is greater than or equal to 80% of the predicted value.
Rationale: Symptoms are continuous throughout the day is incorrect. Continual asthma
symptoms throughout the day are seen with severe persistent asthma.
Daytime symptoms occur more than twice a week is correct. A child with mild
persistent asthma will typically have daytime symptoms more than twice a week,
but not daily.
Nighttime symptoms occur approximately twice a month is incorrect. Nighttime
symptoms occurring approximately twice a month are seen with intermittent
asthma.
Minor limitations occur with normal activity is correct. A child with mild persistent
asthma will have some minor limitations with normal daily activities.
Peak expiratory flow (PEF) is greater than or equal to 80% of the predicted value is
correct. A child with mild persistent asthma will have a PEF greater than or equal to
80% of the predicted value.
