Ineffective Tissue Perfusion: Aneurysms

Question 1

Which type of aneurysm affects only the inner layers of a blood vessel?
A) True aneurysm
B) Dissecting (false) aneurysm
C) Cerebral aneurysm
D) Popliteal aneurysm

Answer 1

B) Dissecting (false) aneurysm

Rationale: A dissecting (false) aneurysm affects only the inner layers of the blood vessel, whereas a true aneurysm affects all three layers of the vessel.

Question 2

A patient presents with a pulsating mass in the abdomen and sudden sharp abdominal pain. Imaging confirms a rupture in the aorta. Based on the patient’s symptoms, what type of aneurysm is most likely?
A) True aneurysm
B) Dissecting aneurysm
C) Cerebral aneurysm
D) Popliteal aneurysm

Answer 2

A dissecting aneurysm involves the rupture of an artery, often presenting with sharp, sudden pain, especially in the aorta. This can lead to life-threatening complications like exsanguination.

Question 3

Which of the following is NOT a common risk factor for aneurysms?
A) Hypertension
B) Smoking
C) High LDL levels
D) Diabetes

Answer 3

D) Diabetes

Rationale: While hypertension, smoking, and high LDL levels are known risk factors for aneurysms, diabetes is not commonly associated with the formation of aneurysms.
