A nurse is caring for a child in the emergency department.

For each of the child's findings, click to specify if the finding is consistent with rheumatic fever or Kawasaki disease. Each finding may support mor e than 1 disease process or none at all. There must be at least 1 selection in every column. There does not need to be a selection in every row.

Assessment of pediatric vital signs requires comparison with normal age-specific ranges because normal values differ significantly from adults. In a 1-year-old toddler, heart rate, respiratory rate, temperature, and blood pressure must be interpreted based on developmental physiology. Respiratory status is especially important because toddlers can deteriorate quickly when respiratory compromise is present. Identifying abnormal findings early allows prompt intervention and prevention of serious complications.

Rationale:
A. A temperature of 37.7°C (99.9°F) is within an acceptable range for a toddler and does not indicate significant fever. Mild variations in temperature can occur due to activity, environment, or time of day. This finding alone would not require immediate provider notification unless accompanied by other concerning symptoms.

B. A heart rate of 110/min is normal for a 1-year-old toddler. Typical resting heart rate for this age group ranges approximately from 90 to 150 beats per minute depending on activity and emotional state. Since this value falls within the expected range, it is not considered abnormal.

C. A respiratory rate of 54/min is elevated for a toddler and should be reported because normal respiratory rate for a 1-year-old is generally about 20 to 40 breaths per minute. Tachypnea may indicate respiratory distress, infection, fever, or metabolic imbalance. Because children compensate early through respiratory changes, this abnormality requires prompt attention.

D. A blood pressure of 88/42 mm Hg is within an expected range for a 1-year-old toddler. Pediatric blood pressure values are naturally lower than adult values due to smaller body size and developmental physiology. This reading does not suggest hypotension unless accompanied by signs of poor perfusion or shock.

Developmental milestones are used to evaluate neurological, motor, and social progression during infancy. At 9 months of age, infants are expected to sit independently, begin pulling to stand, and demonstrate early language development such as babbling. Failure to achieve age-appropriate gross motor and language milestones may indicate developmental delay, neurological impairment, or underlying systemic conditions requiring further evaluation.

Rationale for correct choices:

• Sitting ability: By 9 months, infants are expected to sit independently without trunk support and begin transitioning toward crawling and pulling to stand. This infant is only able to sit with trunk support, which indicates delayed gross motor development. This suggests possible neuromuscular delay, hypotonia, or other developmental concerns affecting core muscle strength and postural control. Delayed sitting ability should be reported for further evaluation.

• Vocalization: By 6 to 9 months of age, infants should be babbling with consonant sounds such as “ba,” “da,” or “ma,” which reflects normal language and social development. The absence of vocalization or babbling at 9 months is a significant developmental delay in speech and language milestones. This may indicate hearing impairment, neurological delay, or global developmental delay. Lack of early communication skills requires further assessment.

Rationale for incorrect choices:

• Tooth eruption: The appearance of a single lower central incisor at 6 months falls within normal variation and does not require concern. Tooth eruption timing differs significantly between infants and is not used as a primary developmental milestone marker. Therefore, this finding is considered normal and does not need to be reported.

• Fine motor skills: No evidence in the assessment suggests abnormal fine motor development, such as inability to grasp objects or poor hand coordination. Without abnormal findings, fine motor skills cannot be identified as delayed.
