The nurse is caring for a client with sinus bradycardia at a rate of 32 beats/min, blood pressure (BP) of 80/42 mm Hg, and reports feeling faint. Which is the appropriate action?

The procedure uses electrical energy to destroy areas of the conduction system: Catheter ablation is a minimally invasive procedure performed to treat abnormal heart rhythms, such as atrial flutter. During the procedure, a catheter is inserted into the heartand used to deliver electrical energy to specific areas of the heart tissue. This energy is used to destroy or ablate the abnormal conduction pathways that are causing the atrial flutter.

Let's go through the other options and explain why they are not accurate:

The procedure stimulates the growth of new pathways between the atria: Catheter ablation does not stimulate the growth of new pathways. Instead, it aims to eliminate or modify existing abnormal pathways in the heart to restore normal electrical conduction.

The procedure uses cold therapy to stop the formation of the flutter waves: Catheter ablation does not use cold therapy. It primarily utilizes radiofrequency energy or other sources of heat to ablate the targeted areas of the heart tissue.

The procedure prevents or minimizes the patient's risk for sudden cardiac death: While catheter ablation can be an effective treatment for certain arrhythmias, including atrial flutter, it is not primarily performed to prevent or minimize the risk of sudden cardiac death. Its main purpose is to restore normal heart rhythm and alleviate symptoms associated with the arrhythmia.

The most important finding to report to the health care provider would be the serum potassium level of 3.0 mEq. This is an extremely low potassium level (normal range is typically 3.5-5.0 mEq/L), which can indicate a potentially life-threatening condition called hypokalemia. Furosemide (Lasix) is a diuretic medication that can cause potassium loss in the urine, and a low potassium level can lead to serious cardiac and muscle abnormalities. It is crucial to report this finding promptly to the health care provider for appropriate intervention and monitoring.

Blood glucose level of 175 mg/dL: While an elevated blood glucose level can be a concern, especially for individuals with diabetes, it is not the most critical finding in this situation. The client's primary concern is hypertension, and the administration of IV furosemide is aimed at managing blood pressure. The elevated blood glucose level should still be addressed and monitored, but it is not as urgent as the low potassium level.

Orthostatic systolic BP decrease of 12 mm Hg: Orthostatic hypotension refers to a significant decrease in blood pressure upon standing up. While it is important to assess and manage orthostatic changes, a decrease of 12 mm Hg in systolic blood pressure alone may not be considered clinically significant. It could be a normal response for some individuals. However, if the client experiences symptoms such as dizziness or lightheadedness upon standing, further evaluation may be necessary. Nonetheless, it is not as urgent as the low potassium level.

Current blood pressure reading of 166/94 mm Hg: While this blood pressure reading indicates hypertension, it is not the most critical finding to report in this situation. The nurse is preparing to administer furosemide (Lasix), which is a medication commonly used to treat hypertension. It is expected that the blood pressure will be high before administering the medication. The goal is to monitor the blood pressure after the administration to assess the effectiveness of the medication.
