The nurse is describing the maturation of various organ systems during toddlerhood to the parents. What would the nurse correctly include in this description?
Myelination of the brain and spinal cord is complete at about 24 months.
Alveoli reach adult numbers by 3 years of age.
Urine output in a toddler typically averages approximately 30 mL/hour.
Toddlers typically have strong abdominal muscles by the age of 2.
The Correct Answer is A
A. Myelination of the brain and spinal cord is a continuous process that begins during fetal development and continues through childhood and adolescence. While significant myelination
occurs during infancy and toddlerhood, it is not complete by 24 months. However, substantial progress in myelination does occur during the toddler years, contributing to the development of motor and cognitive skills.
B. Alveoli reach adult numbers by 3 years of age. This statement is incorrect. Alveoli continue to develop and increase in number after birth, reaching adult numbers around adolescence, not by 3 years of age.
C. Urine output in a toddler typically averages approximately 30 mL/hour. This statement is incorrect. Toddlers typically have higher urine output rates than adults due to their smaller
bladder capacity and higher metabolic rate. The average urine output for a toddler is around 1-2 mL/kg/hour, which varies depending on factors such as hydration status and activity level.
D. Toddlers typically have strong abdominal muscles by the age of 2. This statement is incorrect. While toddlers may develop some abdominal muscle strength through activities such as walking and climbing, their muscle tone and strength are still developing and may not be as strong as in older children or adults.

Correct Answer is A
Explanation
A. Obtain a detailed history.
Obtaining a detailed history is essential to understand the circumstances surrounding the bruises, including how they occurred, where they are located, and whether there is a plausible
explanation for them. This information helps determine whether the bruises are due to accidental injury or potential abuse.
B. Report the suspected abuse to the authorities.
While reporting suspected abuse may ultimately be necessary if there are concerns about the origin of the bruises, obtaining a detailed history is the initial step to gather information and assess the situation before making a report.
C. Ask a psychiatrist to talk with the parents.
Involving a psychiatrist may be appropriate in cases where there are concerns about the child's mental health or the family dynamics, but it may not address the immediate concern of the bruises without first obtaining a detailed history.
D. Separate the child from the parents.
Separating the child from the parents should not be the first action taken without sufficient evidence or reason to believe that the child is in imminent danger. Gathering information through a detailed history is essential before considering such a drastic measure.
Correct Answer is B
Explanation
A. Epiglottitis
Epiglottitis typically presents with rapid onset of severe sore throat, high fever, difficulty swallowing, and drooling due to inflammation and swelling of the epiglottis. It is a medical emergency requiring immediate intervention but is less likely to present with the described symptoms.
B. Bronchiolitis
Bronchiolitis commonly occurs in infants and young children, often during the winter months. It is characterized by symptoms such as coughing, wheezing, nasal congestion, fever, and
respiratory distress. The described symptoms, including coughing, nasal congestion, and intermittent fever, align with bronchiolitis.
C. Influenza
Influenza typically presents with symptoms such as fever, cough, sore throat, body aches, and fatigue. While coughing and fever are common symptoms of influenza, the presence of apneic spells is less typical of influenza and more indicative of lower respiratory tract infections like bronchiolitis.
D. Croup
Croup is characterized by a barking cough, hoarseness, and respiratory distress often accompanied by stridor. While croup shares some symptoms with bronchiolitis, such as coughing, the absence of stridor in the description suggests bronchiolitis as a more likely diagnosis.
