A nurse administers an IV antihypertensive medication, causing an immediate reduction in blood pressure. The baroreceptors respond by attempting to return blood pressure back to normal by accelerating the heart rate
Which term will the nurse use when documenting this phenomenon?
1. Reflex tachycardia
2. Ventricular tachycardia
3. Re-entry tachycardia
4. Supraventricular tachycardia
Correct Answer: 1
Rationale 1: Reflex tachycardia is an accelerated heart rate in response to a sudden drop in blood pressure.
Rationale 2: Ventricular tachycardia occurs when the ventricles of the heart beat greater than 100 beats per minute.
Rationale 3: Re-entry tachycardia is caused by abnormal conduction pathways in the myocardium.
Rationale 4: Supraventricular tachycardia is a rapid heartbeat when the heart rate is generated either in the atria or in the atrioventricular node.
