Which of the following conditions would cause the nurse to monitor for hyperkalemia?
a. Excess aldosterone
b. Acute acidosis
c. Insulin usage
d. Metabolic alkalosis
ANS: B
In acidosis, ECF hydrogen ions shift into the cells in exchange for ICF potassium and sodium; hyperkalemia and acidosis therefore often occur together. Acidosis does not cause excess aldos-terone. Insulin would help treat hyperkalemia, not cause it.
Alkalosis does not lead to hyperkalemia.
