What should the nurse do if a mechanically ventilated ICU patient with hypophosphatemia experiences respiratory muscle weakness, hemolysis, and impaired ATP generation?
Show answer and explanation
Correct answer: Replace phosphate, as depletion impairs respiratory muscle and ATP
Hypophosphatemia impairs ATP generation and respiratory muscle (including diaphragm) contractility and can cause hemolysis; the nurse should check and replace phosphate to restore muscle and cellular energy function.
