What is the benefit of using an arterial line for titrating IV blood pressure medications?
Reduces the risk of infection associated with repeated blood pressure cuff inflations
Provides direct, accurate, and continuous measurement of blood pressure
Allows the patient to be transferred to a lower acuity of care with less monitoring
Increases the accuracy of non-invasive blood pressure measurements
The Correct Answer is B
A. While arterial lines may reduce cuff-related discomfort, infection risk is not their primary benefit.
B. An arterial line provides direct, accurate, and continuous blood pressure monitoring, which is crucial for titrating IV blood pressure medications safely and effectively.
C. Patients with arterial lines generally require higher acuity monitoring, not lower.
D. Arterial lines do not improve the accuracy of non-invasive blood pressure measurements; they provide invasive, more precise data.
