Addison vs. Cushing: The One Lab That Changes Everything with Nurse Mike

A single lab value can flip your entire answer choice, especially when the adrenal glands are involved. We pick up with part two of our Addison’s disease and Cushing syndrome breakdown and focus on what actually helps under pressure: pattern recognition, memory tricks, and the nursing priorities that show up on NCLEX-style questions and real clinical scenarios. First, we walk through Addison’s disease (adrenal insufficiency) by tying low cortisol and low aldosterone to what you’ll see in front of you: fatigue, weight loss, hypotension, hypoglycemia, salt cravings, and that classic hyperpigmentation. Then we lock in the Addison lab pattern, especially the dangerous one: hyperkalemia. We talk through why potassium threatens the heart, what to monitor for on telemetry, and how early recognition can be life-saving. We also cover treatment with hormone replacement therapy like hydrocortisone and fludrocortisone, plus the non-negotiables of patient education, including stress dosing, sodium support, and never stopping steroids abruptly. Then we flip the script to Cushing syndrome (hypercortisolism) and the difference between Cushing disease vs syndrome so you can interpret ACTH correctly. We connect “too much cortisol” to moon face, buffalo hump, truncal obesity, thin extremities, and the lab pattern of high glucose and sodium with low potassium. From there, we hit the nursing considerations that matter most: infection risk, delayed wound healing, bone loss, fall precautions, diet education, and treatment options like surgery, radiation, and cortisol-blocking meds. If you want endocrine to feel predictable instead of random, press play, subscribe for future breakdowns, and share this with a classmate.
