A newborn frequently experiences cyanosis, typically during crying or after feeding. Which cardiac diagnosis is supported by this history?
Ventricular septal defect (VSD)
Atrioventricular canal (AVC) defect
Tetralogy of Fallot
Atrial septal defect (ASD) .
The Correct Answer is C
Choice A rationale
A Ventricular septal defect (VSD) is a hole in the wall separating the two lower chambers of the heart. While it can cause cyanosis, it would not typically cause cyanosis only during crying or after feeding.
Choice B rationale
An Atrioventricular canal (AVC) defect is a combination of heart problems resulting in a defect in the center of the heart. While it can cause cyanosis, it would not typically cause cyanosis only during crying or after feeding.
Choice C rationale
Tetralogy of Fallot is a rare condition caused by a combination of four heart defects that are present at birth. These defects, which affect the structure of the heart, cause oxygen-poor blood to flow out of the heart and into the rest of the body. Infants and children with Tetralogy of Fallot usually have blue-tinged skin because their blood doesn’t carry enough oxygen. This is often more noticeable during episodes of crying or feeding.
Choice D rationale
An Atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). The condition is present at birth (congenital). Small defects might be found by chance and never cause a problem. Some small atrial septal defects close during infancy or early childhood. While it can cause cyanosis, it would not typically cause cyanosis only during crying or after feeding.

Correct Answer is D
Explanation
Choice A rationale
Venous thrombosis is a condition in which a blood clot forms in a vein, typically in the leg. While this condition can cause discomfort and changes in the appearance of the leg, it would not typically cause the leg to become cold and pale or result in the loss of a pulse.
Choice B rationale
Paresthesia refers to abnormal sensations in the body, such as tingling, numbness, or burning. While this condition could potentially cause discomfort, it would not typically cause the leg to become cold and pale or result in the loss of a pulse.
Choice C rationale
Vascular spasm is a sudden, brief tightening of the muscles inside the walls of a blood vessel. While this could potentially cause discomfort and changes in the appearance of the leg, it would not typically cause the leg to become cold and pale or result in the loss of a pulse.
Choice D rationale
Arterial occlusion is the correct answer. This condition involves a blockage in an artery, which can significantly reduce blood flow to the affected area. This could cause the leg to become cold and pale and result in the loss of a pulse.
Correct Answer is ["B","D"]
Explanation
Choice A rationale
The need for Metoprolol (Lopresor) STAT does not necessarily indicate progression to septic shock. Metoprolol is a beta-blocker used to treat high blood pressure, heart failure, and angina. While it may be used in the management of sepsis to control heart rate, its use does not specifically indicate progression to septic shock.
Choice B rationale
The need for Norepinephrine to maintain a mean arterial pressure (MAP) greater than 65 mmHg despite fluid replacement is a strong indicator of septic shock. Norepinephrine is a vasopressor, a type of medication used to increase blood pressure. In septic shock, vasopressors are often required to maintain adequate blood pressure and organ perfusion despite aggressive fluid resuscitation.
Choice C rationale
A serum lactate level less than 2 mmol/L is generally not indicative of septic shock. Elevated lactate levels can indicate tissue hypoperfusion, a condition that may occur in septic shock. However, a level less than 2 mmol/L is typically considered within the normal range.
Choice D rationale
A blood pressure of 70/34 after the fluid bolus could indicate progression to septic shock. In septic shock, despite aggressive fluid resuscitation, blood pressure often remains dangerously low, which can lead to inadequate blood flow to the organs.
