Question

During assessment of a patient who is receiving digoxin, the nurse monitors for findings that would indicate an increased possibility of toxicity, such as:

a. apical pulse rate of 62 beats/min.
b. digoxin level of 1.5 ng/mL.
c. serum potassium level of 2.0 mEq/L.
d. serum calcium level of 9.9 mEq/L.

Answer 1

A serum potassium level of 2.0 mEq/L indicates hypokalemia and increases the risk of digoxin toxicity, which can lead to serious arrhythmias.

Step-by-step explanation:

During the assessment of a patient who is receiving digoxin, a nurse should monitor for several key indicators that could suggest an increased risk of toxicity. Among the options provided, a serum potassium level of 2.0 mEq/L would be a significant concern because it indicates hypokalemia, which can lead to arrhythmias. This low serum potassium level can enhance the toxic effects of digoxin on the heart, increasing the risk of life-threatening arrhythmias. Other options such as an apical pulse rate of 62 beats/min and a digoxin level of 1.5 ng/mL are within normal ranges and are less concerning. A serum calcium level of 9.9 mEq/L is also within normal limits and does not indicate increased risk of digoxin toxicity.
