Which vaccine is now recommended for the immunization of all newborns?

The correct answer is choice B: Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.

Choice A rationale:

Pulmonic stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy. This choice is incorrect because it includes "aortic hypertrophy" and "left ventricular hypertrophy," which are not components of the tetralogy of Fallot. Aortic hypertrophy is not a recognized structural defect in tetralogy of Fallot, and left ventricular hypertrophy is not a characteristic feature of this congenital heart condition.

Choice B rationale:

Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This is the correct choice. Tetralogy of Fallot is characterized by four specific structural defects: pulmonic stenosis (narrowing of the pulmonary valve), ventricular septal defect (hole between the right and left ventricles), overriding aorta (aorta positioned over the ventricular septal defect, receiving blood from both ventricles), and right ventricular hypertrophy (enlargement of the right ventricle due to increased workload).

Choice C rationale:

Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This choice is incorrect because it includes "aortic stenosis," which is not part of the tetralogy of Fallot. In tetralogy of Fallot, the stenosis occurs at the pulmonary valve, not the aortic valve.

Choice D rationale:

Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy. This choice is incorrect. While "overriding aorta" is present in tetralogy of Fallot, "atrial septal defect" and "left ventricular hypertrophy" are not part of this condition. Atrial septal defects involve a hole between the two atria, not the ventricles, and left ventricular hypertrophy is not typically seen in tetralogy of Fallot.

The correct answer is choice A: Signs of stress.

Choice A rationale:

Children often express stress through physical complaints such as stomach pains, headaches, and fatigue. The 9-year-old's complaints of stomach pains, along with the description of aggressive and stubborn behavior, are indicative of stress. Stressors can include academic pressures, family issues, social challenges, or other emotional factors.

Choice B rationale:

Developmental delay refers to a situation where a child's developmental milestones are significantly delayed compared to their peers. This doesn't align with the presented symptoms of stomach pains, aggression, and stubbornness. These symptoms are more indicative of emotional or psychological distress.

Choice C rationale:

While a physical problem could potentially cause emotional stress, the scenario doesn't provide enough information to directly conclude that a physical problem is the primary trigger. Stomach pains could indeed result from emotional stress, and it's important to consider the child's overall well-being.

Choice D rationale:

Lack of adjustment to the school environment can lead to behavioral and emotional challenges, but it's not the most direct explanation for the symptoms described in the scenario. The combination of stomach pains and behavioral changes suggests a more immediate emotional trigger, which is often stress-related.
