In this lesson, we discuss how to rule out bowel obstruction based on history, the physical exam, and imaging.

There are a great variety of medications to use in patients with nausea like antimuscarinic agents, antihistaminic agents, dopaminergic antagonists, and many others.

As an intern, you’ll be in charge of electrolyte repletion almost every day. In this lesson, we cover the symptoms of hypokalemia (low potassium), the formula to calculate the dose, and the best administration route.

In this lesson, our expert teaches you one of the most important skills in the hospital setting—prioritizing your patient’s problem list.

3D analysis of the left ventricle requires four steps: finding the anatomical landmarks, segmenting images into 2D views, marking endocardial borders and generating a 3D ventricle model. In this lesson, our expert explains 3D echo overcomes 2D echo measurement limitations in the case of cardiac remodeling.

With 2D echo, we can assess right ventricular function using measurements like the tricuspid annular plane systolic excursion (TAPSE) or fractional area change (FAC). In this video, you will find out how the right ventricular function assessment can be even more accurate with 3D echo.

The left atrium size is a meaningful prognostic marker for cerebral or cardiovascular disease. In this video, we’ll cover measuring atrial volume with 3D echo and the assessment of intracardiac masses.

3D echo allows you to evaluate the cusp morphology and function in the aortic valve, which hasn’t been possible with 2D echo. In this video, you’ll learn when to use the X plane mode for valve assessment and how 3D echo helps diagnose congenital valve malformations.

While colonoscopy is the standard diagnostic test for colorectal cancer, CT plays a role as a staging tool. In this video, you’ll find out what the apple core lesion is and how to recognize hepatic metastases from colon cancer.

Small bowel obstruction needs a quick diagnostic workup because the patient may need emergency surgery (e.g., when ischemia or perforation are present). In this video, you’ll learn how to recognize small bowel obstruction in a CT study by identifying the three key imaging features.
