A nurse is assessing a toddler who has heart failure. Which of the following findings should the nurse expect?
Bradycardia
Weight loss
Orthopnea
Increased urine output
The Correct Answer is C
A. Bradycardia is not typically expected in toddlers with heart failure; instead, tachycardia (increased heart rate) is more common as the body compensates for decreased cardiac output.
B. Weight loss is generally not a typical finding in toddlers with heart failure; rather, they often experience weight gain due to fluid retention.
C. Orthopnea, or difficulty breathing when lying flat, is a common symptom of heart failure and would be expected in a toddler due to fluid overload affecting respiratory function.
D. Increased urine output is usually not expected in heart failure; rather, fluid retention often leads to decreased urine output as the kidneys respond to the body's fluid balance needs.

Correct Answer is B
Explanation
A. Using a booster seat until the child reaches the appropriate height for a seatbelt is correct and aligns with safety guidelines for child passengers.
B. Allowing a child to ride in the front seat while still using a booster seat is unsafe; children should remain in the back seat until they are at least 13 years old.
C. Ensuring that the child wears a helmet while riding a bicycle is an important safety measure and demonstrates understanding of injury prevention.
D. Teaching the child to avoid running into the street without looking shows awareness of pedestrian safety and the need for supervision and education about traffic safety.
Correct Answer is B
Explanation
A. Tricuspid atresia typically leads to decreased pulmonary blood flow due to the absence of normal blood flow to the lungs.
B. Patent ductus arteriosus results in increased pulmonary blood flow because it allows blood to flow from the aorta to the pulmonary artery, increasing the volume of blood going to the lungs.
C. Coarctation of the aorta can cause decreased blood flow to the lower body, which may not directly relate to increased pulmonary blood flow.
D. Tetralogy of Fallot is characterized by decreased pulmonary blood flow due to right ventricular outflow obstruction, making it not associated with increased pulmonary blood flow.
