a. client with type 2 diabetes taking an oral anti-
diabetic agent

c. d. client taking a thiazide diuretic for
hypertension
client taking non-steroidal anti-
Many salt substitutes are composed of potassium chloride. Heavy use cna
contribute to the development of hyperkalemia. The client should be taught to read labels
and to choose a salt substitute that does not contain potassium. NSAIDs promote the
retention of sodium but not potassium.
An older adult client presents with signs and symptoms related to dig toxicity. Which
age related change may have contributed to this problem?

In a client with hypokkalemia, progressive skeletal muscle weakness is associated with
increasing severity of hypokalemia. The most lifethreatening complication of hypokalemia
is respiratory insufficiency. It is imperative for the nurse to perform a respiratory assessment
first to make sure that the client is not in immediate
