Diabetic Ketoacidosis (DKA): A High-Yield USMLE Topic
Diabetic Ketoacidosis (DKA) is a life-threatening complication of diabetes mellitus, often seen in type 1 diabetes but can also occur in type 2 diabetes under stress conditions. It results from insulin deficiency and increased counter-regulatory hormones, leading to hyperglycemia, ketonemia, and metabolic acidosis.
Action Potentials: How Neurons Communicate on the DAT
Neurons are responsible for transmitting electrical signals throughout the body, enabling everything from muscle movement to thought processes. The action potential is the fundamental mechanism by which neurons communicate, and it’s a high-yield topic on the DAT.
Hyperkalemia: Causes, ECG Changes, and Management
Hyperkalemia (serum K⁺ >5.0 mEq/L) is a life-threatening electrolyte imbalance commonly tested on the USMLE. It affects cardiac conduction, leading to fatal arrhythmias if untreated. Understanding its causes, ECG findings, and emergency management is crucial for both the exam and clinical practice.
