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 B
Explanation
A. "Honor the child's request if she holds her breath.": This instruction is incorrect and potentially dangerous. Giving in to the child's demands when they hold their breath during a temper tantrum can reinforce the behavior and may lead to more frequent and intense tantrums. It's important for parents to remain calm and not give in to unreasonable demands during tantrums.
B. "Establish a structured daily routine for the child.": This instruction is appropriate. A structured daily routine can help toddlers feel secure and provide predictability, which may reduce the likelihood of tantrums. Consistency in meal times, naptimes, and activities can help toddlers know what to expect and feel more in control of their environment.
C. "Place the child in her room alone until the temper tantrum ends.": While it may be necessary to remove a toddler from a potentially dangerous situation during a tantrum, isolating them in their room alone is not recommended. It's important for parents to stay nearby to ensure the child's safety and to provide comfort and support as needed.
D. "Comfort the child during the temper tantrum.": Providing comfort and reassurance to a child during a temper tantrum can be helpful, as long as it's done in a calm and supportive manner. Reassuring words and gentle touch can help the child feel secure and may help to de-escalate the tantrum more quickly.
Correct Answer is A
Explanation
A. Report of diplopia
Diplopia, or double vision, can be a symptom of increased intracranial pressure (ICP) due to its effects on cranial nerve function. Therefore, it is a manifestation that the nurse should recognize as indicating the presence of increased ICP.
B. Hyperactivity
Hyperactivity is not typically associated with increased ICP. Instead, manifestations of increased ICP often include altered level of consciousness, lethargy, or even coma.
C. Nuchal rigidity
Nuchal rigidity, or stiffness in the neck, is not a direct manifestation of increased ICP. It is more commonly associated with meningitis or other conditions affecting the meninges.
D. Report of sore throat
A sore throat is not typically associated with increased ICP unless it is related to complications such as pharyngeal injury or infection.
