Digital Forensics Crime Investigation

When a patient cannot eat enough to meet nutritional needs, how do clinicians decide between feeding through the gastrointestinal tract and delivering nutrients intravenously? In this episode, we examine enteral and parenteral nutrition, their clinical indications, physiological differences, and potential complications. Using real clinical scenarios, we explain how dietitians, nurses, and medical...

What happens to glucose after glycolysis, and how does your body turn carbohydrates, fats, and proteins into usable energy? In this episode of RD Exam in the Car, we break down the Krebs cycle, acetyl-CoA, NADH, FADH₂, and the electron transport chain without overwhelming you with complicated biochemistry. You’ll learn where these processes occur, why oxygen matters, and which concepts are most im...

Glycolysis is one of the most important metabolic pathways tested on the Registered Dietitian exam, yet its enzymes, reactions, and energy calculations can seem overwhelming. In this episode, we simplify how glucose is converted into pyruvate, why ATP is both consumed and produced, and what happens when oxygen availability changes. You’ll learn the key regulatory enzymes, the net energy yield, and...

Fat digestion involves several coordinated processes that are essential for the RD exam. This episode explains how bile salts, pancreatic lipase, micelles, and chylomicrons work together to digest and transport dietary fats. We also examine the absorption of fat-soluble vitamins and the consequences of impaired fat digestion. Strengthen your understanding of gastrointestinal physiology, clinical n...

Protein digestion is a favorite RD exam topic because it connects gastrointestinal physiology, enzymes, amino acid absorption, and nitrogen metabolism. In this episode, we follow protein from the stomach through the small intestine and explain what happens to amino acids after they enter the bloodstream. We’ll also focus on the enzymes, hormones, and metabolic pathways you’re most likely to encoun...

Carbohydrates are one of the body’s primary energy sources, but before they can produce energy, they must be digested, absorbed, transported, and metabolized. This episode follows carbohydrates from the mouth to the bloodstream and then into the cells, connecting digestive physiology with insulin, glucagon, glycogen, and glucose metabolism. For the RD exam, the key is understanding not just where...

When should nutrition go through the gastrointestinal tract, and when should it go directly into the bloodstream? This episode uses two fictional patients to make the difference between enteral nutrition and parenteral nutrition easy to remember. We examine gastrointestinal function, access, clinical appropriateness, and complications rather than relying on simplistic rules. Two original practice...

The Nutrition Care Process is one of the most important frameworks to understand for the RD exam. In this episode, we follow a fictional hospitalized patient from the first nutrition assessment through diagnosis, intervention, and follow-up. You’ll learn how to distinguish assessment data from a nutrition diagnosis and how the PES statement connects the problem to its cause and evidence. Then test...

This episode explores the transformative impact of rapid 3D scanning technologies on modern crime scene investigation, detailing how terrestrial laser scanners and photogrammetry create precise digital twins that preserve evidence with sub-millimeter accuracy. We examine the integration of these tools with cyber forensic techniques, their advantages over traditional methods, and real-world applica...

They didn't just sling product — they built a system. This episode breaks down how the 007 Bloods turned BonTon into one of Dallas's most profitable drug corridors, the hierarchy that kept it running, and the federal hammer that finally came down. No politics. Just the streets.
