Question

question 49
the device or instrument that is used to measure arterial blood pressure by hand is a:
o cardiac catheterization
o treadmill stress test
o sphygmomanometer
o sphygmostasis

question 50
the surgical technique that brings a new blood supply to heart muscles by detouring around blocked atherosclerotic coronary arteries is called a(n):
o coronary artery bypass
o cardiac tuning
o venal bypass
o mitral commissurotomy

Explanation:

For Question 49, a sphygmomanometer is the instrument used to measure arterial blood - pressure by hand. Cardiac catheterization is an invasive procedure for diagnosing heart conditions, treadmill stress test assesses heart function during exercise, and sphygmostasis is related to stopping bleeding.
For Question 50, coronary artery bypass is the surgical technique that brings a new blood supply to heart muscles by detouring around blocked atherosclerotic coronary arteries. Cardiac tuning is not a standard surgical term in this context, venal bypass is not related to heart - muscle blood supply in this way, and mitral commissurotomy is a procedure for the mitral valve.

Answer:

Question 49: C. sphygmomanometer
Question 50: A. coronary artery bypass
