With a pre-dialysis heart rate of 44 for a patient taking digitalis, what should the nurse suspect?

A pre-dialysis heart rate of 44 beats per minute is bradycardia, which is a significant slowing of the heart rate. In a patient taking digitalis, this can often indicate drug toxicity. Digitalis, or digoxin, is commonly utilized to manage conditions such as heart failure and atrial fibrillation by increasing the force of heart contractions and regulating heart rhythm.

However, a known side effect of digitalis is that it can depress heart rate, leading to bradycardia, especially if the therapeutic range is exceeded. When heart rates drop significantly, as in this case, it raises the suspicion of digitalis toxicity, potentially requiring immediate nursing intervention and assessment of the patient’s symptoms, as well as adjustments in medication or dosage. Recognizing this relationship between heart rate and digitalis is crucial for safe patient care.

In contrast, other potential issues, such as heart failure, dehydration, or low blood pressure, do not specifically correlate as closely with the patient's current presentation of bradycardia under digitalis therapy. While they can be related to a heart rate disturbance, they do not directly point to digitalis toxicity in the same clear manner.
