What is the advantage of teaching to the family about continuous cycling peritoneal dialysis (CCPD) or continuous ambulatory peritoneal (CAPD) for adolescents who require dialysis?

Tetralogy of Fallot is a congenital heart defect characterized by a combination of four specific heart abnormalities:
Ventricular septal defect (VSD): A hole in the wall (septum) between the two lower chambers (ventricles) of the heart.
Overriding aorta: The aorta is positioned over both the left and right ventricles, allowing oxygen-poor (deoxygenated) blood from the right ventricle to mix with oxygen-rich (oxygenated) blood from the left ventricle.
Pulmonic stenosis: Narrowing of the pulmonary valve or artery, which restricts blood flow from the right ventricle to the lungs.
Right ventricular hypertrophy: The right ventricle becomes thicker and more muscular as it works harder to pump blood against the narrowed pulmonary valve or artery.
The combination of these defects results in deoxygenated blood from the right ventricle being pumped into the systemic circulation, leading to cyanosis (blueness of the skin) due to decreased oxygen levels in the arterial blood.
The other options (A, B, and C) describe different congenital heart defects but do not specifically result in cyanosis due to deoxygenated blood entering the systemic circulation:

A. Coarctation of the aorta results in the narrowing of the aorta but does not directly lead to cyanosis from the mixing of oxygen-poor blood.

B. Aortic stenosis involves narrowing of the aortic valve but does not typically result in cyanosis in the same way as Tetralogy of Fallot.

C. Patent ductus arteriosus (PDA) involves a connection between the aorta and pulmonary artery but does not cause cyanosis from mixing to the extent seen in the Tetralogy of Fallot.

When obtaining the history of a child with suspected rheumatic fever, the nurse should consider the following information to be most significant:

B. A recent episode of pharyngitis.

Explanation:

Rheumatic fever often follows an untreated or inadequately treated streptococcal pharyngitis (strep throat) infection caused by Group A Streptococcus bacteria. Therefore, a recent episode of pharyngitis is a key piece of information in the context of rheumatic fever. It is important to assess whether the child had a sore throat, fever, and other symptoms of streptococcal infection that may have triggered the development of rheumatic fever.

While the other symptoms (vomiting, lack of interest in food, fever) may be important for the overall assessment and management of the child, they are not as directly associated with the development of rheumatic fever as a recent episode of pharyngitis caused by Group A Streptococcus. Rheumatic fever is an autoimmune response to untreated streptococcal infection, and its diagnosis is often linked to the presence of preceding streptococcal pharyngitis.
