Which of the following nursing considerations is important when administering adenosine?

When administering adenosine, it's crucial to be aware that the medication may cause transient asystole for up to 15 seconds. Adenosine is used primarily for the rapid conversion of certain types of supraventricular tachycardia (SVT) to a normal sinus rhythm. Upon administration, it can temporarily disrupt electrical activity in the heart, leading to a pause in cardiac output, which presents as asystole. This effect is typically brief, lasting only a few seconds, and highlights the need for close monitoring of the patient's cardiac rhythm during and immediately after its administration.

Understanding this transient asystole is essential for preparing both the nursing staff and the patients for what they might observe following administration. Proper monitoring is critical to ensure safety and prompt intervention if necessary. Other options may present misleading information about the administration and effects of adenosine, but recognizing the risk of transient asystole ensures that nursing staff can appropriately respond to patient needs during this time.
