Endocrine
Feedback loops gone wrong: too much or too little of a hormone, and the crises at each extreme. Diabetes and its emergencies anchor the system — the highest-frequency endocrine content on the NCLEX.
Diabetes Mellitus (Type 1 & 2)
DM High-yield in researchThe anchor page — insulin deficiency vs resistance, sick-day rules, hypo- vs hyperglycemia recognition.
Diabetic Ketoacidosis
DKA High-yield in researchAbsolute insulin lack → ketones and acidosis — the K⁺-before-insulin sequence.
Hyperosmolar Hyperglycemic State
HHS High-yield in researchExtreme glucose without ketones — the older-adult presentation and the DKA-vs-HHS table.
Hypothyroidism & Myxedema Coma
High-yield in researchThe slowed-down body — lifelong levothyroxine teaching, and the myxedema emergency.
Hyperthyroidism & Thyroid Storm
High-yield in researchThe sped-up body — storm triggers, and post-thyroidectomy airway + calcium watch.
Cushing’s Syndrome
in researchCortisol excess — usually iatrogenic; the steroid-taper link and masked infection.
Addison’s Disease & Adrenal Crisis
in researchCortisol deficiency — never stop steroids abruptly; crisis is shock that needs hydrocortisone.
SIADH & Diabetes Insipidus
SIADH in researchThe water-balance mirror image — sodium direction, urine output, and correction speed limits.
Parathyroid & Calcium Disorders
in researchTrousseau and Chvostek signs — and the post-thyroidectomy tie-in.
Pheochromocytoma
in researchParoxysmal catecholamine surges — the hypertensive triad and don’t-palpate-the-abdomen.
