The nurse is reinforcing teaching with the caregiver of 5-year-old twins regarding urinary tract infections (UTIs). The caregiver is puzzled about why her daughter has had three urinary tract infections but her son has had none. She reports that their diets and fluid intake are similar. Which statement would be accurate for the nurse to tell this mother?

“Girls tend to urinate less frequently than boys, making them more susceptible to UTIs.”

“It is unlikely that your daughter is practicing good cleaning habits after she voids.”

“Girls need more vitamin C than boys to keep their urinary tract healthy, so your daughter may be deficient in vitamin C.”

“A girl’s urethra is much shorter and straighter than a boy’s, so it can be contaminated fairly easily.”

Answer and Explanation

The Correct Answer is D

Choice A reason: Urination frequency varies individually, not by gender, and isn’t a primary UTI risk factor. The shorter female urethra explains higher UTI rates, making this inaccurate and incorrect compared to the anatomical reason for the daughter’s recurrent infections in the 5-year-old twins.

Choice B reason: Assuming poor hygiene without evidence is speculative and less relevant than anatomical differences. The shorter urethra is the primary UTI risk in girls, making this blaming and incorrect compared to explaining the biological factor contributing to the daughter’s infections in the teaching.

Choice C reason: Vitamin C may support urinary health but isn’t gender-specific or a primary UTI cause. The shorter female urethra directly increases contamination risk, making this irrelevant and incorrect compared to the anatomical explanation for the daughter’s recurrent UTIs in the caregiver’s twins.

Choice D reason: Girls’ shorter, straighter urethras allow easier bacterial access to the bladder, explaining higher UTI rates compared to boys. This anatomical fact aligns with pediatric urology evidence, making it the accurate statement to clarify the daughter’s recurrent infections for the caregiver of the twins.

Correct Answer is B

Explanation

Choice A reason: 300-800 ml/day is too low for a child with sickle cell disease, risking dehydration and sickling crises. 1500-2000 ml maintains hydration, making this insufficient and incorrect compared to the adequate fluid intake needed to prevent complications in the child’s home care.

Choice B reason: 1500-2000 ml/day ensures adequate hydration for a child with sickle cell disease, reducing blood viscosity and sickling risk. This aligns with pediatric hematology guidelines for preventing crises, making it the correct fluid intake recommendation for the caregiver to support the child’s health at home.

Choice C reason: 2500-3200 ml/day exceeds typical needs for a child, risking fluid overload without added sickle cell benefit. 1500-2000 ml is optimal, making this excessive and incorrect compared to the recommended fluid range for managing sickle cell disease effectively at home.

Choice D reason: 1000-1200 ml/day is below the optimal range for a child with sickle cell disease, increasing dehydration and crisis risk. 1500-2000 ml better supports hydration, making this inadequate and incorrect compared to the fluid intake needed to prevent sickle cell complications.

A. “At birth, the infant’s right and left ventricle are about the same size.” B. “The child’s heart doesn’t mature and function like an adult’s until between 8 and 10 years of age.” C. “The heart rate of the child decreases whenever the child experiences a fever.” D. “Between the ages of 5 and 6, the child’s left ventricle grows to about two times the size of the right.”

Correct Answer is A

Explanation

Choice A reason: At birth, the infant’s right and left ventricles are nearly equal in size due to fetal circulation demands. This aligns with pediatric cardiology, making it the correct statement demonstrating understanding of the newborn’s cardiovascular system as discussed in the nurses’ review session.

Choice B reason: The heart matures earlier, with adult-like function by early childhood, not 8-10 years. Equal ventricle size at birth is accurate, making this incorrect, as it overestimates the timeline for cardiovascular maturation in the nurse’s understanding of the child’s heart development.

Choice C reason: Heart rate typically increases with fever in children, not decreases, due to metabolic demands. Equal ventricle size at birth is correct, making this inaccurate and incorrect compared to the true statement about the infant’s cardiovascular system in the nurses’ review.

Choice D reason: The left ventricle grows slightly larger but not twice the right’s size by 5-6 years. Equal ventricles at birth is accurate, making this incorrect, as it exaggerates ventricular growth in the nurse’s understanding of the child’s cardiovascular system development.
