Correct Answer is B

Explanation

A. Spinal cord perfusion is not monitored with a pulmonary artery catheter; it typically requires different neuromonitoring techniques.
B. Hemodynamic status is accurately monitored using a pulmonary artery catheter (also called a Swan-Ganz catheter), which provides information on cardiac output, pulmonary artery pressures, and other cardiovascular parameters.
C. Intracranial pressure is monitored using devices like an intraventricular catheter or subarachnoid bolt, not a pulmonary artery catheter.
D. Renal function is assessed through laboratory tests (e.g., BUN, creatinine) and urine output, not via a pulmonary artery catheter

A. Sinus bradycardia B. First degree heart block C. Normal sinus rhythm D. Sick sinus syndrome

Correct Answer is C

Explanation

A. Sinus bradycardia is characterized by a heart rate less than 60 beats/min, but in this case the rate is exactly 60, which is normal lower limit.
B. First degree heart block involves a prolonged PR interval (>0.20 seconds); here, the PR interval is normal (0.16 seconds).
C. Normal sinus rhythm has regular P waves and QRS complexes, a normal PR interval (0.12–0.20 seconds), and a heart rate between 60–100 beats/min.
D. Sick sinus syndrome is characterized by irregular rhythms and abnormal sinus node function, which is not indicated here.
