The nurse is preparing to administer adenosine to a patient with supraventricular tachycardia When a patient presents with supraventricular tachycardia (SVT), rapid and precise intervention is often required to restore normal heart rhythm. Among the first-line pharmacologic treatments employed is adenosine, a potent antidysrhythmic agent known for its rapid onset and short half-life. The nurse plays a crucial role in preparing and administering this medication safely and effectively.
Preparation begins with verifying the healthcare provider’s order, ensuring the correct dosage based on the patient’s weight and clinical condition. Adenosine is typically administered as a rapid intravenous (IV) push, followed immediately by a saline flush to facilitate its swift entry into the circulation. The nurse must confirm the availability of the medication in the correct form and concentration, as well as ensure that emergency equipment and resuscitation facilities are readily accessible. This is vital because adenosine administration can sometimes cause transient side effects, including chest discomfort, flushing, or brief asystole.
Prior to administration, the nurse assesses the patient’s vital signs, including heart rate, blood pressure, and oxygen saturation. It is also important to review the patient’s allergy history and current medications, as certain drugs or conditions might contraindicate the use of adenosine or increase the risk of adverse reactions. For example, patients with second- or third-degree AV block, sick sinus syndrome, or known hypersensitivity require careful consideration or alternative therapies.

The nurse is preparing to administer adenosine to a patient with supraventricular tachycardia The actual preparation involves drawing up the prescribed dose into a syringe, typically labeled as a rapid IV push, often over 1 to 2 seconds. The nurse then prepares a saline flush—usually 5 to 20 mL of normal saline—to follow immediately after the adenosine dose. The infusion site is checked for patency, and the nurse ensures that the IV line is patent and positioned proximally to the heart to facilitate rapid drug delivery.
When administering adenosine, the nurse instructs the patient to remain still and breathe normally, as movement can interfere with the procedure. The medication is injected rapidly through a large vein, preferably in the antecubital fossa or another large vein, to ensure quick circulation to the heart. Immediately afterward, the nurse administers the saline flush at the same rapid rate, followed by removing the syringe and keeping the IV line patent for potential additional doses if the initial attempt does not convert the rhythm.
The nurse is preparing to administer adenosine to a patient with supraventricular tachycardia Monitoring the patient closely during and after administration is essential. The nurse observes the cardiac rhythm via ECG continuously, noting any changes such as conversion to normal sinus rhythm or adverse reactions. The patient may experience brief sensations like chest pressure, flushing, or a sense of impending doom, which are typically transient. The nurse must be prepared to manage these symptoms and provide reassurance.
In case the initial dose does not resolve the SVT, the healthcare provider may order additional doses of adenosine, often doubling the previous dose, with careful monitoring. The nurse’s role is to ensure proper administration, observe for efficacy, and remain vigilant for potential adverse effects, including arrhythmias or respiratory issues.

In summary, administering adenosine for SVT requires meticulous preparation, rapid and correct technique, and vigilant monitoring. The nurse’s expertise ensures the safety and comfort of the patient while facilitating effective treatment of this common arrhythmia.
