- A. Intense thirst and dry, sticky mucous membranes
- B. Dependent oedema and moist lung sounds
- C. Carpopedal spasm with facial twitching

Hypernatremia commonly causes cellular dehydration, producing thirst, dry mucous membranes, restlessness and neurological changes. Oedema and neck vein distension suggest fluid excess, while carpopedal spasm is associated more closely with low calcium.
