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 A
Explanation
A. Preschoolers believe their illness is punishment for their misbehavior:This statement is true. Preschool-aged children often have a limited understanding of illness and may associate it with punishment. They might think that their illness is a consequence of something they did wrong. As a nurse, it’s essential to address these misconceptions and provide age-appropriate explanations to help them understand their condition better.
B. Preschoolers are interested in what happens to the body after death: Preschoolers may have curiosity about death and what happens afterward, but their understanding is typically limited. They may ask simple questions about death and may need age-appropriate explanations about the concept. Providing information in a sensitive and honest manner can help address their curiosity and alleviate fears.
C. Adolescents worry more about death than the physical changes that can occur as a result of the illness: Adolescents facing terminal illness may have complex emotions and concerns about both death and the physical changes associated with their illness. It's important to acknowledge and address both aspects of their experience, providing opportunities for adolescents to express their feelings and concerns in a supportive environment.
D. Toddlers personify death as being a type of monster: Toddlers often have limited understanding of death and may personify it in different ways, including as a monster or some other abstract concept. It's essential for guardians to provide comfort and reassurance to toddlers who may experience fear or confusion about death. Providing simple and concrete explanations about death, tailored to their developmental level, can help alleviate anxiety.
Correct Answer is D
Explanation
A. Green zone reading on peak expiratory flow meter:
A green zone reading on a peak expiratory flow meter indicates that the child's peak expiratory flow rate (PEFR) is within the normal or stable range. This would not typically be indicative of an exacerbation of asthma. In fact, a green zone reading suggests that asthma is well-controlled.
B. Rhinitis:
Rhinitis, or inflammation of the nasal mucosa, is a common symptom in individuals with asthma, but it is not necessarily indicative of an exacerbation of asthma. Rhinitis can occur due to allergic or non-allergic triggers and may be present even when asthma is well-controlled.
C. Axillary temperature of 37.2°C (99°F):
An axillary temperature of 37.2°C (99°F) is within the normal range for body temperature and is not indicative of an exacerbation of asthma. While fever can occur during exacerbations of asthma, it is not a universal symptom and may be absent in some cases.
D. Hacking, nonproductive cough:
This is the correct option. A hacking, nonproductive cough is a common symptom of asthma exacerbation. During an exacerbation, the airways become inflamed and constricted, leading to coughing. The cough may be dry and unproductive, and it is often worse at night or early in the morning.
