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 D
Explanation
A. Ophthalmologist: This healthcare professional specializes in the diagnosis and treatment of eye disorders. While eye problems can occur in infants, congenital talipes equinovarus specifically involves foot deformities rather than eye issues. Therefore, a referral to an ophthalmologist wouldn't be appropriate for this condition.
B. Nutrition counselor: A nutrition counselor provides guidance on diet and nutrition-related issues. While nutrition is essential for overall health, it's not directly related to the treatment of congenital talipes equinovarus. Therefore, a referral to a nutrition counselor wouldn't typically be part of the care plan for this condition.
C. Speech therapist: Speech therapists, also known as speech-language pathologists, specialize in evaluating and treating communication and swallowing disorders. However, congenital talipes equinovarus doesn't affect speech or swallowing. Therefore, a referral to a speech therapist wouldn't be relevant for this condition.
D. Orthopedic specialist: An orthopedic specialist is a healthcare professional who specializes in the diagnosis and treatment of musculoskeletal conditions, including congenital abnormalities like clubfoot. They are trained to assess the severity of the deformity and develop a treatment plan, which may include non-surgical or surgical interventions to correct the foot alignment. Therefore, a referral to an orthopedic specialist is the most appropriate choice for an infant with congenital talipes equinovarus.

Correct Answer is C
Explanation
A. "What is your pain level right now?": This response doesn't directly address the child's question about mortality and may deflect the conversation away from the child's concerns. While assessing pain is important, it should not be the immediate response to a question about mortality.
B. "Your doctor will be able to answer your questions tomorrow.": This response delays addressing the child's concerns and may leave the child feeling anxious or unsupported in the meantime. It's important for the nurse to provide immediate support and reassurance when a child expresses fears or worries.
C. "It sounds like you are worried. Tell me what you have been told.": This response acknowledges the child's emotions and invites them to share their thoughts and concerns. It opens up a dialogue between the nurse and the child, allowing the nurse to provide appropriate support and information based on the child's understanding and perspective.
D. "It's natural to worry about death, but you should focus your energy on getting better.": While this response acknowledges the child's worry, it may come across as dismissive or minimizing of the child's concerns about mortality. It's important to validate the child's emotions and offer support rather than redirecting their focus away from their worries.
