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 B
Explanation
Choice A rationale
A pleural friction rub, which is a grating sound caused by the inflammation of the pleural surfaces during respiration, is not typically associated with cardiac tamponade. It is more commonly associated with conditions affecting the lungs, such as pneumonia or pleurisy.
Choice B rationale
Distended neck veins are a classic sign of cardiac tamponade. This occurs due to increased pressure in the right atrium as a result of the impaired filling of the ventricles. This is a critical sign that should be reported immediately.
Choice C rationale
Widening pulse pressure (an increase in the difference between systolic and diastolic blood pressure) is not typically associated with cardiac tamponade. In fact, cardiac tamponade more commonly presents with a narrowed pulse pressure.
Choice D rationale
Bradycardia, or a slow heart rate, is not typically a sign of cardiac tamponade. More commonly, tachycardia, or a fast heart rate, is observed in response to decreased cardiac output.
Correct Answer is B
Explanation
Choice A rationale
A 39-year-old patient experiencing tenderness and swelling in the right calf following a flight may be experiencing deep vein thrombosis (DVT), a condition that can lead to serious complications such as pulmonary embolism if not treated. However, DVT is not immediately life-threatening in most cases.
Choice B rationale
A 58-year-old patient on anticoagulants for atrial fibrillation presenting with black stools is likely experiencing gastrointestinal bleeding, a common side effect of anticoagulant therapy. This can lead to severe blood loss, anemia, and hypovolemic shock, which can be life-threatening if not promptly addressed. Therefore, this patient should be prioritized for assessment.
Choice C rationale
A 67-year-old patient with a gangrenous foot ulcer and a weak pedal pulse likely has peripheral artery disease and an infection that could lead to sepsis if not treated. However, while this condition needs medical attention, it is not as immediately life-threatening as gastrointestinal bleeding.
Choice D rationale
A 50-year-old patient reporting sudden, severe upper back pain could be experiencing a number of conditions, ranging from musculoskeletal strain to aortic dissection. While an aortic dissection is a medical emergency, without additional symptoms such as chest pain, shortness of breath, or loss of consciousness, this patient is not the highest priority.
