Prescription for digoxin
🟨 Digoxin is a critical finding because furosemide can cause further potassium loss, and hypokalemia increases the risk of digoxin toxicity.
🟨 When potassium is low, digoxin binds more easily at its action sites, which can lead to dangerous cardiac effects.
🟨 This client already has a potassium level below normal, so adding furosemide could worsen the imbalance and increase harm.
🟨 The nurse should recognize that concurrent digoxin therapy makes the low-potassium situation especially concerning before giving the new diuretic.
🟨 Therefore, the prescription for digoxin is one of the findings that indicates a contraindication or major concern requiring follow-up.
Client verbal report
🟨 The client reports diarrhea, dry mouth, and unusual thirst for the past three days, which suggests possible fluid volume depletion.
🟨 Furosemide is a loop diuretic, so giving it to a client who may already be dehydrated can worsen fluid loss.
🟨 This can increase the risk of hypovolemia, dizziness, electrolyte imbalance, and renal compromise.
🟨 The nurse should identify these symptoms as important assessment findings that need further evaluation before administering the medication.
🟨 Therefore, the client verbal report is one of the findings that indicates a contraindication or significant concern.
Potassium level
🟨 The client’s potassium level is 3.2 mEq/L, which is below the expected range and indicates hypokalemia.
🟨 Furosemide can further lower potassium because it increases urinary excretion of electrolytes.
🟨 Worsening hypokalemia can lead to muscle weakness, dysrhythmias, and increased risk of digoxin toxicity.
🟨 Because the potassium is already low before the first dose, the nurse should recognize this as a serious reason to question the prescription.
🟨 Therefore, the potassium level is one of the findings that indicates a contraindication or major concern.
Blood pressure
🟨The blood pressure of 122/68 mm Hg is within an acceptable range and does not by itself indicate a contraindication to furosemide.
🟨Although furosemide can lower blood pressure, this current reading is not the most concerning finding here.
BUN
🟨The BUN of 19 mg/dL is within the expected reference range and does not independently suggest renal impairment severe enough to contraindicate furosemide.
🟨It is less concerning than the signs of dehydration and low potassium.
