CRITICAL THINKING FOR COMPLETE EXAM PREPARATION AND
ACADEMIC SUCCESS
Question 1
A nurse is assessing a 6-month-old infant during a well-baby visit. Which developmental
milestone is most appropriate for this age?
A. Walking independently
B. Rolling from back to abdomen
C. Speaking two-word sentences
D. Using a pincer grasp fully
Correct Answer: B. Rolling from back to abdomen
Rationale:
At approximately 6 months of age, infants commonly roll over, sit with support, and begin
transferring objects between hands. Rolling from back to abdomen is an expected gross motor
milestone.
• Walking independently usually occurs around 12 months.
• Two-word sentences typically develop around 2 years.
• A mature pincer grasp develops around 9–12 months.
,The nurse should always compare developmental findings with expected age-related milestones
to identify delays early.
Question 2
The nurse is teaching parents about safe sleep practices for their newborn. Which statement by
the parent indicates understanding?
A. “I will place my baby on the stomach to sleep.”
B. “Soft blankets should be placed around the baby.”
C. “My baby should sleep on a firm mattress on the back.”
D. “Co-sleeping helps decrease sudden infant death syndrome.”
Correct Answer: C. “My baby should sleep on a firm mattress on the back.”
Rationale:
The safest sleep position for infants is supine (on the back) on a firm mattress without loose
bedding or toys. This significantly reduces the risk of sudden infant death syndrome (SIDS).
• Stomach sleeping increases SIDS risk.
• Soft blankets and pillows can cause suffocation.
• Co-sleeping increases risk for accidental suffocation and injury.
Safe sleep education is one of the most important preventive teachings in pediatric nursing.
Question 3
A child with dehydration is admitted after several episodes of vomiting and diarrhea. Which
assessment finding is most concerning?
A. Moist mucous membranes
B. Capillary refill of 4 seconds
C. Urine output every 4 hours
D. Presence of tears while crying
Correct Answer: B. Capillary refill of 4 seconds
Rationale:
,Delayed capillary refill greater than 3 seconds suggests poor perfusion and possible moderate to
severe dehydration.
Other signs of dehydration include:
• Dry mucous membranes
• Sunken fontanel
• Tachycardia
• Decreased urine output
• Absence of tears
Moist mucous membranes and tears suggest adequate hydration.
Question 4
The nurse is caring for a toddler hospitalized with respiratory syncytial virus (RSV). Which
isolation precaution is most appropriate?
A. Airborne precautions
B. Droplet and contact precautions
C. Protective isolation
D. Standard precautions only
Correct Answer: B. Droplet and contact precautions
Rationale:
RSV spreads through respiratory secretions and contaminated surfaces. Droplet and contact
precautions help prevent transmission.
Appropriate measures include:
• Hand hygiene
• Gloves and gown use
• Private room if possible
• Mask use during close contact
Airborne precautions are used for illnesses such as measles or tuberculosis.
, Question 5
A nurse is assessing pain in a 3-year-old child. Which pain assessment tool is most appropriate?
A. Numeric rating scale
B. FLACC scale
C. Glasgow Coma Scale
D. Mini-Mental Status Exam
Correct Answer: B. FLACC scale
Rationale:
The FLACC scale evaluates:
• Face
• Legs
• Activity
• Cry
• Consolability
It is commonly used for infants and young children unable to reliably describe pain numerically.
• Numeric scales are more appropriate for older children.
• Glasgow Coma Scale assesses neurological status.
• Mini-Mental Status Exam assesses cognition in adults.
Question 6
Which finding would the nurse expect in a child with iron-deficiency anemia?
A. Bradycardia
B. Pale conjunctiva
C. Increased appetite
D. Jaundice
Correct Answer: B. Pale conjunctiva
Rationale:
Iron-deficiency anemia commonly presents with:
