What is the purpose of intra-arterial catheters?

• A. To monitor arterial blood pressure
• B. To administer medication
• C. For retrieving blood samples only
• D. To insert intravenous fluids

Answer: (A)

Intra-arterial catheters are primarily utilized to monitor arterial blood pressure continuously. This is critical in managing patients in various medical situations, particularly in intensive care settings, where precise blood pressure readings are necessary for effective treatment and monitoring. These catheters provide real-time data that helps healthcare providers make informed decisions regarding a patient's hemodynamic status. While some intra-arterial catheters may also permit the administration of medications or retrieval of blood samples, their main and most crucial function centers around the continuous and accurate monitoring of blood pressure. This capability is essential in guiding the administration of fluids and medications and in assessing the overall cardiovascular status of the patient.
