Question

1. the phase in the cardiac cycle in which chambers relax between contractions is called:

○ lumen
○ dia/stole
○ auscult/ation
○ oc/clus/ion

1. what is a stricture of the carotid arteries in the neck that can lead to stroke called?

○ carotid edema
○ carotid athroma
○ carotid prolapse
○ carotid stenosis

Explanation:

Question 45

To solve this, we analyze each option:

• "lumen" refers to the inside space of a tube (like a blood vessel), not a cardiac cycle phase.
• "diastole" (the option is written as dia/stole, likely a typo for diastole) is the phase where the heart chambers relax between contractions.
• "auscultation" is the act of listening to body sounds (like heart or lung sounds), not a cardiac cycle phase.
• "occlusion" means a blockage, not a relaxation phase.

Analyzing each option:

• "carotid edema" is swelling of the carotid artery, not a stricture.
• "carotid athroma" (likely a typo, but "atheroma" is a fatty deposit, not a stricture).
• "carotid prolapse" is a protrusion, not a stricture.
• "carotid stenosis" is the narrowing (stricture) of the carotid arteries, which can lead to stroke.

Answer:

B. dia/stole (correct term is diastole)
