A nurse is assessing a child who has a congenital heart defect. The nurse should recognize that which of the following defects is associated with increased pulmonary blood flow?
Coarctation of the aorta
Patent ductus arteriosus
Tetralogy of Fallot
Tricuspid atresia
The Correct Answer is B
A. Coarctation of the aorta
Coarctation of the aorta involves a narrowing of the aorta, leading to decreased blood flow to the lower body. It is not associated with increased pulmonary blood flow.
B. Patent ductus arteriosus
Patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that usually closes shortly after birth, remains open. This allows blood to flow from the aorta into the pulmonary artery, increasing pulmonary blood flow. Therefore, option B is correct.
C. Tetralogy of Fallot
Tetralogy of Fallot is a congenital heart defect characterized by four abnormalities, including a ventricular septal defect (VSD), pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta. While it can lead to cyanosis due to right-to-left shunting, it is not primarily associated with increased pulmonary blood flow.
D. Tricuspid atresia
Tricuspid atresia involves the absence of the tricuspid valve, leading to a lack of direct blood flow from the right atrium to the right ventricle. It usually presents with decreased pulmonary blood flow rather than increased pulmonary blood flow.

Correct Answer is C
Explanation
A. Steatorrhea: Steatorrhea refers to the presence of fat in the stool, which can indicate malabsorption or digestive issues, but it is not a typical symptom of a urinary tract infection (UTI). Therefore, it is not relevant to consider steatorrhea in the context of a UTI.
B. Jaundice: Jaundice is characterized by yellowing of the skin and eyes due to elevated levels of bilirubin in the blood. It is typically associated with liver or gallbladder problems and is not a common symptom of a UTI. Therefore, it is not relevant to consider jaundice in the context of a UTI.
C. Incontinence: Incontinence, or the inability to control urination, can be a symptom of a UTI in toddlers. UTIs can cause irritation of the bladder, leading to urgency, frequency, and in some cases, incontinence. Therefore, incontinence is a relevant finding to consider in the context of a UTI.
D. Rebound tenderness: Rebound tenderness is a sign of peritoneal irritation and is typically associated with conditions affecting the abdomen, such as appendicitis or peritonitis. It is not a typical symptom of a UTI. Therefore, it is not relevant to consider rebound tenderness in the context of a UTI.
Correct Answer is ["B","C","D"]
Explanation
A. "Schedule a time for your child to receive the pneumococcal vaccine within 2 weeks."
This statement is incorrect. Pharyngitis caused by group A beta-hemolytic streptococci (GABHS) is typically treated with antibiotics, but it does not necessitate pneumococcal vaccination. Pneumococcal vaccination is recommended for other purposes, such as preventing pneumonia and invasive pneumococcal disease.
B. "Provide your child with their own towel for drying their face and hands at home."
This statement is correct. Group A streptococci (GAS) can be transmitted through respiratory droplets or by direct contact with infected secretions. Providing the child with their own towel can help prevent the spread of the infection to other family members.
C. "Replace your child's toothbrush 24 hours after beginning antibiotic therapy."
This statement is correct. It is recommended to replace the child's toothbrush after starting antibiotic therapy to reduce the risk of re-infection with group A streptococci (GAS).
D. "Your child can return to school 24 hours after their first dose of antibiotics."
This statement is correct. After initiating antibiotic therapy for GABHS pharyngitis, the child is usually considered non-contagious and can return to school after completing 24 hours of antibiotic treatment.
E. "Replace your child's orthodontic appliances prior to beginning antibiotic therapy."
This statement is incorrect. There is no specific recommendation to replace orthodontic appliances before starting antibiotic therapy for GABHS pharyngitis unless otherwise advised by a dentist or healthcare provider.
