The nurse assesses for acidosis in the client with which assessment data?
a. Serum sodium level of 130 mEq per liter and peripheral edema
b. Serum sodium level of 144 mEq per liter and tachycardia
c. Serum potassium level of 6.5 mEq per liter and flaccid paralysis
d. Serum potassium level of 4.5 mEq per liter and hyperactive deep tendon reflexes
C
When acidosis is present, the hydrogen ion concentration of the extracellular fluid (ECF) is increased above normal. The physiologic action to reduce the ECF hydrogen ion concentration is to move the hydrogen ions into the cells in exchange for potassium ions, thereby maintaining the electroneutrality of the intracellular fluid. As a result, acidosis is accompanied by hyperkalemia, which diminishes nerve and skeletal muscle excitability, causing flaccid paralysis.
