NCLEX-RN
A rare autosomal‑dominant channelopathy that produces episodic, often profound, skeletal‑muscle weakness. The attacks are precipitated by a rapid intracellular shift of potassium, leaving the serum concentration low enough to silence muscle excitability. Because the presentation mimics Guillain‑Barré, myasthenia gravis, and electrolyte disorders, nurses must spot the distinctive pattern and act quickly to prevent life‑threatening complications.
