When a telemetry patient receives IV potassium chloride replacement, what must be monitored closely throughout the infusion?
Answer: Cardiac rhythm for signs of hyperkalemia and arrhythmias
IV potassium directly affects cardiac electrical activity; rapid or excessive administration can cause hyperkalemia and life-threatening arrhythmias, requiring continuous telemetry monitoring.
A patient on IV amiodarone develops new high-degree AV block on the telemetry monitor. What is the most appropriate immediate action?
Answer: Notify the physician and slow or stop the infusion per protocol
Amiodarone's AV node blocking properties can cause conduction delays; new heart block requires immediate physician notification and possible infusion adjustment.
What is the maximum recommended rate for IV potassium chloride infusion via a peripheral IV line in adults?
Answer: 10 mEq/hour
The standard maximum peripheral IV rate for potassium is 10 mEq/hour to prevent sudden hyperkalemia, cardiac arrhythmias, and vein irritation.
Which antiarrhythmic medication carries a black box warning for pulmonary toxicity and requires continuous telemetry monitoring during IV administration?
Answer: Amiodarone
Amiodarone has FDA black box warnings for pulmonary toxicity, hepatotoxicity, and proarrhythmia, and requires continuous cardiac monitoring during infusion.
A telemetry technician notices QT prolongation on the monitor after a patient is started on a new antibiotic. What is the correct action?
Answer: Notify the nurse or physician of the QT change immediately
New QT prolongation following initiation of an antibiotic is a clinically significant finding that must be reported immediately due to the risk of Torsades de Pointes.
In the telemetry setting, lidocaine is used primarily to treat which condition?
Answer: Suppression of ventricular arrhythmias
Lidocaine is a Class IB antiarrhythmic that stabilizes ventricular myocardium by blocking fast sodium channels, and is used for suppressing ventricular arrhythmias such as VT.
