Which structural defects constitute tetralogy of Fallot?
Pulmonic stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy.
Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.
Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.
Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy.
The Correct Answer is B
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.

Correct Answer is D
Explanation
The correct answer is choice D. Birth history.
Choice A rationale:
The heading "Chief complaint" is used to document the primary reason for the patient seeking medical attention, such as their main symptom or concern. This is usually stated in the patient's own words and provides context for the visit, but it does not encompass information about the circumstances of birth or prematurity.
Choice B rationale:
"Review of systems" involves a systematic approach to inquire about the patient's current symptoms or physical complaints across different body systems. It helps to identify any additional issues the patient might not have mentioned initially, but it does not pertain to birth history or prematurity.
Choice C rationale:
"Present illness" is the section where the nurse documents the patient's current health concern, including the details of the symptoms, their onset, duration, and any associated factors. However, it does not encompass information about the circumstances of birth or prematurity.
Choice D rationale:
"Birth history" is the most appropriate heading for recording information about the infant's delivery, including any difficulties during delivery and the fact that the baby was born prematurely. This information is relevant for understanding the infant's medical background and potential risk factors associated with prematurity.
Correct Answer is ["A","C","D"]
Explanation
The correct answers are choices A, C, and D: Tachycardia, Hyperthermia, and Vomiting.
Choice A rationale:
Tachycardia. Tachycardia, an abnormally fast heart rate, is a classic manifestation of thyroid storm. In this life-threatening condition, there is an excessive release of thyroid hormones, leading to increased metabolic rate and subsequent cardiovascular effects such as tachycardia.
Choice B rationale:
Constipation. This choice is incorrect for thyroid storm. Hyperthyroidism typically leads to increased bowel motility and can cause diarrhea rather than constipation.
Choice C rationale:
Hyperthermia. This is a correct choice. Thyroid storm is associated with severe hyperthermia due to the increased metabolic rate caused by excessive thyroid hormones. The body's temperature regulation is disrupted, leading to dangerously high body temperatures.
Choice D rationale:
Vomiting. This is a correct choice. Gastrointestinal symptoms, including vomiting and nausea, can occur in thyroid storm due to the heightened metabolic state. Thyroid storm affects various systems, including the gastrointestinal system, leading to symptoms like vomiting.
Choice E rationale:
Hypotension. This choice is incorrect for thyroid storm. Thyroid storm is more likely to cause hypertension rather than hypotension due to the increased cardiac output and sympathetic stimulation.
