Final answer:
Special attention must be paid to potassium levels, kidney function, and signs of digitalis toxicity in patients taking Digitalis medication, due to its narrow therapeutic index and potential for serious side effects.
Step-by-step explanation:
If a patient is taking a Digitalis medication, special attention must be paid to the patient's potassium levels, kidney function, and signs of digitalis toxicity. Digitalis medications, which include digoxin, are used to treat various heart conditions such as heart failure and atrial fibrillation by increasing the efficiency of the heart and controlling the rate and rhythm of the heartbeat. However, these medications have a narrow therapeutic index, meaning the difference between a beneficial dose and a harmful one is small. Patients on Digitalis need to be monitored for symptoms of toxicity, which can include nausea, vomiting, dizziness, confusion, and abnormal heart rhythms. It's also essential to maintain appropriate potassium levels as low potassium can increase the risk of digitalis toxicity. Kidney function tests are important since the kidneys are responsible for excreting digoxin; impaired function may lead to accumulation of the drug in the body.
