A 6-month-old male infant is brought to a pediatrician by his guardian for scheduled immunizations. The boy was born at 39 weeks gestation via spontaneous vaginal delivery. He is up to date on all vaccines and is meeting all developmental milestones. The infant is generally healthy; however, the guardian is concerned about multiple patches of bluish discolorations on the skin overlying the lower back and sacrum. A review of medical records indicates that these patches have been present since birth. On further review the child was placed into protective services due to neglect and abuse by his biological family. On physical examination, his vital signs are normal. The pediatrician notes the presence of multiple blue-brown patches over the lumbosacral region, buttocks, and back. These patches are soft and nontender on palpation. Which of the following is the best next step in management of the infant?

A 5-year-old child is brought to the emergency department after being hit by a motor vehicle on the way to school. According to paramedics, the child's right leg was severely crushed in the accident. After evaluation, the physician recommends immediate limb-saving surgery to preserve the leg and prevent complications. However, the parents refuse to consent to the surgery. They explain that they heard about a similar case where a child died after limb-saving surgery, and they believe the procedure might lead to amputation or death. Despite the physician's explanation that the surgery is intended to save the limb, the parents remain adamant in their refusal. What is the next best step?

A 26-year-old G1P0 female who is 39 weeks pregnant presents to the emergency department in labor. She reports following her primary care physician’s recommendations throughout her pregnancy and has not had any complications. During delivery, the baby’s head turtled back into the vaginal canal and did not advance any further. The neonatal intensivist was called for shoulder dystocia and a baby girl was able to be delivered vaginally 6 minutes later. Upon initial assessment, the baby appeared pale throughout, had her arms and legs flexed without active motion, and had some flexion of extremities when stimulated.

A 1-minute-old newborn is being examined by the pediatric nurse. The nurse auscultates the heart and determines that the heart rate is 89/min. The respirations are spontaneous and regular.

When the arms are extended by the nurse they flex back quickly. What is this patient’s Apgar score?

A six-year-old male presents to the pediatrician for a well child visit. The patient’s parents report that they are struggling to manage his temper tantrums, which happen as frequently as several times per day. They usually occur in the morning before school and during mealtimes, when his parents try to limit how much he eats. The patient often returns for second or third helpings at meals and snacks throughout the day. The patient’s parents have begun limiting the patient’s food intake because he has been gaining weight. They also report that the patient recently began first grade but still struggles with counting objects and naming letters consistently. The patient sat without support at 11 months of age and walked at 17 months of age. He is in the 99th percentile for weight and 5th percentile for height. On physical exam, he has almond-shaped eyes and a downturned mouth. He has poor muscle tone. Which of the following additional findings would most likely be seen in this patient?

A 3-year-old boy is brought to the physician for evaluation of developmental delay. He could sit alone at 12 months and started walking with support at the age of 2 years.
