After administering 40 mEq of potassium chloride, a nurse evaluates the client's response. Which manifestations indicate that treatment is improving the client's hypokalemia? (Select all that apply.)
a. Respiratory rate of 8 breaths/min
b. Absent deep tendon reflexes
c. Strong productive cough
d. Active bowel sounds
e. U waves present on the electrocardiogram (ECG)
ANS: C, D
A strong, productive cough indicates an increase in muscle strength and improved potassium imbalance. Active bowel sounds also indicate treatment is working. A respiratory rate of 8 breaths/min, absent deep tendon reflexes, and U waves present on the ECG are all manifestations of hypokalemia and do not demonstrate that treatment is working.
