In this high-yield episode of Master USMLE, we tackle a classic Step 2 CK challenge: hypocalcemia.

A malnourished patient presents with cramps, twitching, and perioral numbness. His calcium is low—but is that the real issue?

We walk you step-by-step through how to approach low calcium on the exam:

• How to confirm true hypocalcemia

• The three key questions you must ask first

• Why magnesium is often the missing piece

• When to check PTH, and how to interpret it

• The difference between gland failure and PTH resistance

This episode trains your clinical reasoning, not just your memory. Learn how to break down these questions just like you would on test day.
