Correct Answer is B
Explanation
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.
Correct Answer is B
Explanation
A. CPAP is typically used for simpler obstructive sleep apnea, while BiPAP is often used for more complex cases.
B. BiPAP delivers two different pressure levels: a higher pressure during inhalation (IPAP) and a lower pressure during exhalation (EPAP), which helps patients breathe more easily.
C. CPAP delivers a continuous, single pressure level throughout the breathing cycle, not two different pressures.
D. This describes CPAP rather than BiPAP.
