Question

question 121
a pulmonary infarction actually means:
pulmonary incompetence
slowed blood flow
lung blood flow blockage
pulmonary valve stenosis

question 122
which of the following cranial nerves are responsible for carrying nerve impulses associated with the special senses?
1, 2, 5, 8
1, 2, 7, 10
1, 2, 8, 9
1, 2, 8, 11

question 123
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 121: Pulmonary infarction occurs when there is a blockage in the blood flow to the lungs. Pulmonary incompetence refers to a valve - related issue (not infarction), slowed blood flow is a general term and not specific to infarction, and pulmonary valve stenosis is a valve narrowing (not infarction).
• Question 122: Cranial nerve 1 (olfactory - smell), 2 (optic - vision), 8 (vestibulocochlear - hearing and balance) are associated with special senses. Cranial nerve 5 is trigeminal (somatic sensations like touch on face), 7 is facial (motor for facial muscles and some taste), 9 is glossopharyngeal (taste and swallowing), 10 is vagus (many functions including in the gut), and 11 is accessory (motor for neck and shoulder muscles).
• Question 123: Carotid stenosis is the narrowing (stricture) of the carotid arteries which can lead to stroke due to reduced blood flow or embolization. Carotid edema is swelling, atheroma is a fatty deposit (but stenosis is the stricture), and prolapse is a displacement (not relevant here).

Answer:

• Question 121: lung blood flow blockage
• Question 122: 1, 2, 8
• Question 123: carotid stenosis
