A client with cystitis receives a prescription for phenazopyridine. Which information should the nurse explain to the client about its therapeutic effect?

 

Choice A reason: Administering potassium is not the primary action for treating digoxin toxicity. While hypokalemia can exacerbate digoxin toxicity, the initial step is to assess and stabilize the patient’s overall condition, including acid-base and electrolyte balance. Potassium administration may be considered if hypokalemia is present, but it is not the first-line treatment.

Choice B reason: Cardioversion is not typically used to treat digoxin toxicity. Digoxin toxicity can cause various arrhythmias, but the treatment focuses on stabilizing the patient and addressing the toxicity itself2. Cardioversion may be considered in life-threatening arrhythmias, but it is not the primary intervention.

Choice C reason: Checking acid-base and electrolyte values is crucial in managing digoxin toxicity. Digoxin toxicity can lead to electrolyte imbalances, particularly hyperkalemia, which can be life-threatening. Assessing and correcting these imbalances is essential for stabilizing the patient and preventing further complications.

Choice D reason: Giving digoxin by another route to slow absorption is not an appropriate action. The primary treatment for digoxin toxicity involves stopping the medication and administering digoxin-specific antibody fragments (Fab) if necessary. These antibodies bind to digoxin, neutralizing its effects and allowing for its excretion.

Choice A reason: Withholding the scheduled dose and notifying the healthcare provider is the correct action because the client’s heart rate is significantly low at 48 beats per minute. Labetalol, a beta-blocker, can further reduce the heart rate, potentially leading to bradycardia or other cardiac complications. It is crucial to inform the healthcare provider to reassess the medication regimen and ensure the client’s safety.

Choice B reason: Administering the dose and monitoring the client’s blood pressure regularly is not advisable in this scenario. Although monitoring blood pressure is important, the primary concern here is the client’s low heart rate. Administering labetalol could exacerbate bradycardia, leading to severe complications.

Choice C reason: Assessing for orthostatic hypotension before administering the dose is a good practice but not the most critical action in this situation. The client’s low heart rate poses a more immediate risk than orthostatic hypotension. Therefore, withholding the medication and notifying the healthcare provider is a higher priority.

Choice D reason: Applying a telemetry monitor before administering the dose is useful for continuous cardiac monitoring, but it does not address the immediate concern of the client’s low heart rate. The priority should be to withhold the medication and consult the healthcare provider to prevent potential bradycardia.
