At what age does an infant typically start to sit without support?
3 months
12 months
6 months
9 months
Infants usually achieve sitting without support around six months as part of gross motor development. This milestone reflects trunk and head control improvements. Balance and muscle strength at this age enable independent sitting.
What is the normal resting heart rate range for a 1-year-old child?
60-80 beats per minute
120-160 beats per minute
80-120 beats per minute
40-60 beats per minute
A healthy one-year-old typically has a resting heart rate between 80 and 120 beats per minute. Heart rates outside this range may indicate cardiac or systemic problems. Pediatric heart rate norms vary by age group.
Which vaccine is routinely given at 12 months to protect against measles, mumps, and rubella?
MMR
IPV
DTaP
Hib
The MMR vaccine is usually administered at 12 - 15 months to immunize against measles, mumps, and rubella. It is a live-attenuated vaccine given in two doses. Ensuring timely vaccination reduces the risk of outbreaks.
A child presents with rhinorrhea, cough, and low-grade fever for two days. Which diagnosis is most likely?
Strep throat
Bacterial pneumonia
Viral upper respiratory infection
Measles
Rhinorrhea, cough, and low-grade fever are classic signs of a viral upper respiratory infection. These infections are common in children and often resolve without antibiotics. Bacterial pneumonia and strep throat typically present with higher fever and focal findings.
Using the formula (age in years × 2) + 8, estimate the weight of a typical 2-year-old child in kilograms.
10 kg
16 kg
12 kg
14 kg
The formula estimates a 2-year-old's weight as (2 × 2) + 8 = 12 kg. This quick tool aids initial dosing and equipment sizing. It provides a reasonable approximation in healthy children.
At what age does an infant typically develop the pincer grasp?
3 months
6 months
9 months
12 months
The pincer grasp emerges around nine months when infants can use thumb and index finger to pick up small objects. This fine motor milestone demonstrates developing hand-eye coordination. It is a key indicator of neurologic development.
A 4-year-old presents with a barking cough and inspiratory stridor, worse at night. What is the most likely diagnosis?
Asthma
Croup
Epiglottitis
Bronchiolitis
Croup causes a characteristic barking cough and stridor due to laryngeal inflammation, often worse at night. It is usually viral and managed with humidified air or nebulized epinephrine in moderate to severe cases. Epiglottitis typically presents with drooling and severe distress.
Calculate the appropriate single dose of acetaminophen (15 mg/kg) for a 15-kg child.
300 mg
200 mg
225 mg
150 mg
Acetaminophen dosing is 15 mg per kg, so 15 kg × 15 mg = 225 mg. Weight-based dosing ensures therapeutic effect while minimizing toxicity risk. Always verify concentration when drawing dose.
What is the expected respiratory rate for a 4-year-old child at rest?
12-20 breaths per minute
30-40 breaths per minute
20-30 breaths per minute
40-60 breaths per minute
A normal resting respiratory rate for a 4-year-old ranges from 20 to 30 breaths per minute. Rates above this may indicate respiratory distress or illness. Pediatric respiratory norms vary by age.
At what age is the second dose of the MMR vaccine typically administered?
4-6 years
2 years
9 months
12-15 months
The second MMR dose is usually given at 4 - 6 years of age, ensuring long-term immunity. The first dose is administered at 12 - 15 months. This schedule maximizes vaccine effectiveness.
Which of the following is a sign of moderate dehydration in a toddler?
Dry mucous membranes
Absent tears
Lethargy
Sunken eyes
Sunken eyes indicate moderate dehydration due to fluid loss affecting orbital tissues. Dry mucous membranes and absent tears can occur in mild to severe cases, while lethargy suggests severe dehydration. Accurate assessment guides rehydration therapy.
Which tool assesses pediatric patients using appearance, work of breathing, and circulation to skin?
APGAR score
Braden scale
Glasgow Coma Scale
Pediatric Assessment Triangle
The Pediatric Assessment Triangle rapidly evaluates appearance, work of breathing, and circulation to skin for initial triage. It helps providers identify critical illness without equipment. Other scales serve different purposes.
At what age do infants usually transfer objects from one hand to the other?
3 months
6 months
12 months
9 months
By six months, infants typically transfer objects hand-to-hand, reflecting increasing coordination. This milestone is part of fine motor development. Variations may indicate need for developmental evaluation.
A 5-year-old has fever, rash, conjunctivitis, and a "strawberry tongue." Which illness is most likely?
Scarlet fever
Kawasaki disease
Measles
Rubella
Kawasaki disease presents with prolonged fever, rash, conjunctivitis, and mucosal changes like strawberry tongue. It requires prompt treatment to prevent coronary artery aneurysms. Scarlet fever rash and tongue changes differ in pattern.
For an anaphylactic reaction, epinephrine is given intramuscularly at 0.01 mg/kg. What dose is appropriate for a 25-kg child?
0.3 mg
0.5 mg
0.15 mg
0.25 mg
The recommended IM epinephrine dose is 0.01 mg per kg, so 25 kg × 0.01 mg/kg = 0.25 mg. Accurate weight-based dosing is critical to manage anaphylaxis. Overdose can cause significant cardiac effects.
A 7-month-old infant has not rolled from front to back. At what age should this milestone be achieved, indicating a possible delay?
10 months
4 months
8 months
6 months
Rolling front to back typically appears by four months, reflecting early gross motor control. Absence beyond this age may signal neuromuscular or developmental issues. Early recognition prompts further evaluation.
A 3-year-old presents with high fever, cough, coryza, conjunctivitis, and Koplik spots. What is the most likely diagnosis?
Fifth disease
Rubella
Measles
Scarlet fever
Koplik spots on the buccal mucosa are pathognomonic for measles, accompanied by the three C's: cough, coryza, and conjunctivitis. This viral illness requires supportive care and airborne precautions. Rubella and scarlet fever have different clinical features.
What is the maintenance intravenous fluid requirement per hour for a 20-kg child using the Holliday-Segar method?
50 ml/hr
75 ml/hr
100 ml/hr
62.5 ml/hr
Holliday-Segar calculates 100 ml/kg for first 10 kg and 50 ml/kg for next 10 kg: total 1500 ml/24 hr, which equals 62.5 ml/hr. Proper fluid management is essential in pediatric care. Over- or underhydration can lead to complications.
A 9-year-old who missed the HPV vaccine requires a catch-up schedule. How many doses are recommended and at what interval?
Three doses at 0, 1, and 6 months
Two doses at 0 and 6 months
Two doses at 0 and 1 month
Single dose at school entry
For children aged 9 - 14, the CDC recommends a two-dose HPV series with the second dose given six months after the first. This schedule elicits a strong immunologic response. Three-dose series apply to older adolescents or immunocompromised patients.
In compensated pediatric shock, which clinical sign is most reliable to detect early circulatory compromise?
Hypotension
Altered mental status
Prolonged capillary refill
Tachycardia
Prolonged capillary refill is an early indicator of poor perfusion in compensated shock, as other signs like hypotension appear late in children. Tachycardia and mental status changes occur later. Early detection guides prompt intervention.
