Pediatrics

A 12-month-old boy is brought to the office for a routine well-child visit. Three months ago, he was hospitalized for a 5-day history of high fever, polymorphic rash, bilateral conjunctival injection, and cervical lymphadenopathy. He was diagnosed with Kawasaki disease and treated successfully with high-dose intravenous immunoglobulin (IVIG) and aspirin. He is currently taking no medications. The mother expresses concern that her son is not yet walking independently and only says "mama" and "dada" specifically. He pulls to stand, cruises along furniture, uses a neat pincer grasp, and points to objects. His length, weight, and head circumference are at the 50th percentile. Physical examination is normal. His immunization record shows he received all recommended vaccines at ages 2, 4, and 6 months. Which of the following is the most appropriate management for this patient today?

A 1-week-old male newborn is brought to the pediatric clinic for his initial newborn follow-up visit. He was born at 39 weeks gestation via an uncomplicated spontaneous vaginal delivery to a 28-year-old primigravida. His birth weight was 3.4 kg (7 lb 8 oz). Current vital signs include a temperature of 36.8°C (98.2°F), heart rate of 140/min, and respiratory rate of 40/min. Physical examination reveals a healthy, vigorous neonate with normal muscle tone, a flat anterior fontanelle, and symmetric primitive reflexes. He received the first dose of the hepatitis B vaccine at birth and is feeding well on demand. His first-time parents are eager to understand what to expect regarding his neurodevelopmental progress over the coming years.

Arrange the following developmental milestone clusters in the chronological order of their expected emergence in a typically developing healthy child.

Match the following key socioemotional and play milestones to the most typical chronological age at which they first emerge during normal pediatric development.

A 30-month-old boy is brought to the office by his parents for a routine well-child visit. His parents express concern regarding his development. They note that he does not play cooperatively with other children at the local park, preferring to play independently next to them, and he frequently refuses to share his toys. Additionally, they are worried because he cannot yet pedal a tricycle or draw a circle. On physical examination, the child is active and cooperative. He walks up the examination step stool by placing both feet on each step and successfully jumps in place. He builds a tower of eight blocks and holds a crayon to make vertical lines. He speaks in two- to three-word phrases, has a vocabulary of approximately 100 words, and refers to himself as "I." His speech is understood by the physician roughly half the time. Which of the following is the most appropriate next step in management?

Parents bring their 2-year-old son to the pediatric clinic because they are highly concerned about his frequent, severe temper tantrums. When he is denied a toy, he frequently throws himself on the floor, kicks, and screams. During the most severe episodes, he cries vigorously, stops breathing, and turns slightly blue around the lips before taking a deep breath and recovering spontaneously. He has never lost consciousness.

On developmental assessment, the boy walks well, runs, kicks a ball, and can build a tower of 6 cubes. He points to objects he wants and brings books to his parents to read. His vocabulary consists of "mama," "dada," "dog," and "no." He does not put two words together. He makes good eye contact, smiles reciprocally, and plays alongside his older sister in the waiting room.

A 5-year-old boy is brought to the clinic for a well-child examination prior to starting kindergarten. His medical history is notable for severe polyarticular juvenile idiopathic arthritis. For the past 6 months, his condition has been exceptionally well controlled on a regimen of subcutaneous etanercept and oral methotrexate. His mother states he has been entirely asymptomatic. A review of his immunization records shows that he received all required infant and toddler vaccinations up to age 2, but he has not yet received any of his standard preschool booster vaccines. The mother also expresses concern that her son cannot yet copy a diamond or independently tie his shoelaces. Observation in the clinic reveals he can skip, copy a triangle, and accurately count to 10. Vital signs and physical examination are normal. Which of the following is the most appropriate management plan for this patient today?

A 4-year-old boy is brought to the pediatric clinic in late September for a well-child visit. He was diagnosed with moderate-to-severe Crohn disease 6 months ago. His current medications include infliximab, a tumor necrosis factor-alpha (TNF-α) inhibitor, which has led to clinical remission and appropriate weight gain. He has no other medical conditions. His immunizations were up to date until his 18-month visit. He is now due for his routine preschool vaccinations, and the parents also request the seasonal influenza vaccine. His vital signs are temperature 36.8°C (98.2°F), heart rate 98/min, and respiratory rate 20/min. Physical examination is unremarkable.

A 2-day-old male newborn is evaluated in the nursery for a new-onset skin rash. He was born at 39 weeks gestation via uncomplicated spontaneous vaginal delivery. Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. The infant has been breastfeeding well and has had normal bowel and bladder function. Temperature is 37.1 C (98.8 F), heart rate is 140/min, and respiratory rate is 40/min. Physical examination reveals multiple erythematous macules and papules with central 1- to 2-mm yellow-white pustules scattered across the trunk and proximal extremities. The palms and soles are spared. The remainder of the examination is unremarkable. Which of the following is the most appropriate next step in management?

A 2-month-old girl is brought to the clinic for her first well-child examination. She was born at 39 weeks gestation via spontaneous vaginal delivery. Her mother has a history of severe, refractory Crohn's disease, which has been managed with regular infusions of infliximab throughout the pregnancy, with the final dose administered at 36 weeks gestation. The infant's newborn screen was normal. She has been exclusively breastfed and is gaining weight well. On examination, the infant appears well. She smiles responsively, makes cooing sounds, and tracks the examiner's face past the midline. When placed in the prone position, she is able to lift her head to 45 degrees. The mother expresses concern that the infant is not yet reaching for objects or rolling over. Her tone and reflexes are normal. She previously received the Hepatitis B vaccine at birth. Which of the following is the most appropriate next step in management regarding her immunizations and development?

During routine well-child visits, developmental surveillance is a critical component of preventive care. Arrange the following communication and language milestones in the correct chronological order of their typical emergence in a healthy developing child, from earliest to latest.

A mother brings her daughter, aged 4 years and 2 months, to the pediatric clinic for a health maintenance visit. The child was diagnosed with minimal change disease one month ago and has been taking daily oral prednisone at a dose of 2 mg/kg for the past 24 days. Her vital signs are within normal limits for her age, and physical examination reveals mild facial puffiness but is otherwise unremarkable. The mother expresses concern regarding her daughter's development, noting that the child can hop on one foot and copy a cross, but is unable to skip or draw a person with more than three body parts. A review of the electronic health record shows the patient received all recommended infant and toddler immunizations up to 18 months of age, but she has not yet received any of her preschool vaccine boosters. Which of the following is the most appropriate management regarding this patient's immunizations and development?

Match the following classic clinical descriptions of benign neonatal skin findings with their most likely diagnoses.

A pediatric clinic is creating a quick-reference chart for residents to use during routine well-child evaluations. The chart aims to integrate various developmental domains across the first three years of life. Arrange the following key developmental milestones in their correct chronological sequence of expected acquisition, starting with the earliest.

A 12-month-old boy is brought to the clinic for a routine well-child visit. His mother reports that he pulls to a stand and cruises along furniture, but she is concerned because he is not yet walking independently. He uses a neat pincer grasp to pick up small pieces of food. He says "mama" and "dada" specifically to his parents but uses no other recognizable words. He plays peek-a-boo and waves goodbye. The boy is due for his routine 12-month immunizations, which include the live-attenuated measles-mumps-rubella (MMR) and varicella vaccines. However, his 6-year-old sister recently underwent a hematopoietic stem cell transplant for acute myeloid leukemia and is currently severely immunocompromised. The mother asks if it is safe for the boy to receive his scheduled vaccines given his sister's condition. Which of the following is the most appropriate next step in management?

An 18-month-old toddler is evaluated at a primary care clinic after relocating from another state. The parents note that he has had nasal congestion and a mild cough for the past 48 hours. His temperature is 37.8°C (100.0°F), pulse is 110/min, and respirations are 24/min. Physical examination demonstrates clear rhinorrhea and a mildly erythematous posterior oropharynx. Auscultation reveals clear breath sounds bilaterally without wheezing or crackles. He is playful, runs around the examination room, scribbles on a piece of paper, and uses approximately 15 different words. Review of his medical record indicates that his last immunizations were administered at the age of 6 months. Which of the following is the most appropriate next step in the management of this patient?

A medical student is preparing a comprehensive timeline of preventive care milestones to use during a pediatric clerkship. The student aims to map out the exact age at which specific universal screening tests are first introduced for a healthy, term, asymptomatic pediatric patient with no family history of genetic or metabolic disease. According to the American Academy of Pediatrics (AAP) Bright Futures guidelines, arrange the following universal screening interventions in chronological order based on the age they should FIRST be administered, from earliest to latest.

A 4-year-old girl is brought to the office by her father for a well-child examination. The father is worried about her overall development. He states that since she started attending a new preschool three months ago, she has frequently engaged in conversations with an "imaginary friend" in her bedroom. Furthermore, she intermittently repeats syllables when she is very eager to talk about her day. The father is also concerned because she is unable to draw a square or ride a two-wheeled bicycle, milestones that her older sibling had already achieved by age 5. Her medical history is unremarkable. On examination, the patient appears well-nourished and cooperative. She is able to hop on one foot and catch a bounced ball. When given paper and crayons, she successfully draws a person with four body parts and copies a cross, but she cannot draw a square or a triangle. During the visit, her speech is entirely understandable to the physician, and she exhibits no facial grimacing, jaw jerking, or eye blinking when repeating syllables. Which of the following is the most appropriate next step in management?
