c.) Potassium level because a common trigger for toxicity is hyperkalemia.
d.) CBC to check the patient’s WBCs because they may have a UTI.
b.) Dignoxin level because the elderly are at increased risk for digoxin toxicity.
Which labs should the nurse monitor after increasing a patient’s lisinopril from 10 mg to 40 mg QD?

b.) BUN, Potassium, Creatinine
A patient with heart failure is prescribed Digoxin & a loop diuretic. The nurse knows that what finding would increase the patient’s risk of developing Digoxin toxicity?

d.) Albumin 5 g/dL
b.) Potassium 2 mEg/L
