Propranolol administration requires careful monitoring of which type of heart rhythm?

• A. Chamber size
• B. EKG
• C. Heart rate variability
• D. Oxygen saturation levels

Answer: (B)

Monitoring the EKG is crucial when administering propranolol because this medication is a non-selective beta-adrenergic antagonist that can affect the heart's electrical conduction system. Propranolol can lead to changes in heart rate, rhythm, and potentially cause bradycardia or heart block, which can be detected on an EKG. The EKG provides real-time data regarding the heart's electrical activity, allowing healthcare providers to track any changes in rhythm or conduction that may occur as a result of propranolol therapy. This monitoring helps ensure patient safety and allows for timely interventions if any adverse effects arise. While considering the other options, chamber size is important for assessing cardiac function and heart disease but is not directly monitored through propranolol administration. Heart rate variability can be informative but is not as immediately relevant for safety during propranolol treatment as EKG changes. Oxygen saturation levels are essential to monitor in many clinical situations, but they do not provide specific information regarding the heart rhythm affected by propranolol. Thus, EKG monitoring is the most relevant and critical aspect to ensure appropriate management during propranolol use.
