What is the most likely source of the artifact noted in this 2D color Doppler image?

When imaging a patient in the cardiac ICU, you image an Impella cannula placement in the long axis view, where should the cannula measured and what is the correct length for this measurement?

While performing a routine echocardiogram on a newborn in the nursery you obtain the following 2D image in the apical 4 chamber view. What is the most likely cardiac diagnosis based on this 2D image?

A neonatal patient presents for an echocardiographic evaluation to rule out anomalous pulmonary venous return. The sonographer optimizes the color Doppler Nyquist limit and obtains a high parasternal/suprasternal short-axis view, frequently referred to as the “crab view”, to visualize the pulmonary veins draining into the left atrium. Which of the following statements best describes following 2D image with color Doppler?

Which cardiac structure is noted by the arrow in this 3D image?

During a routine echocardiogram on a newborn you visualize a structure with a left to right shunt in the high left parasternal view. Anatomically, what is this structure and which structures does it form a direct conduit between?

All future benefits and costs are measured in constant 2026 dollars. Which NPV setup keeps the dollar units consistent?

Annual hospital visits fall from 30,000 to 15,000 after a program begins. Over the same period, visits fall by 6,000 in comparable untreated cities. A well-matched valuation study supports a shadow price of $4,000 per avoided visit. If the comparison-city trend is the appropriate counterfactual, which annual benefit estimate is best supported?

Projects A and B each cost $10 million at t = 0 and have the same NPV at a 3% discount rate. All of A’s benefits arrive at the end of year 25, while all of B’s benefits arrive at the end of year 5. If the discount rate rises, which project’s NPV has the larger decrease in dollar terms, holding the cash flows fixed?

The nurse is caring for an infant with a known diagnosis of Tetralogy of Fallot when the infant suddenly becomes cyanotic and irritable during a crying episode. The nurse should first position the infant in the (supine, knee-chest, prone) position and then administer (aspirin, furosemide (Lasix), morphine) to reduce oxygen demand and calm the infant.
