HESI A2 QUESTIONS AND ANSWERS 100% ACCURATE.
What is the only artery in the body to carry oxygen-poor blood?
A. renal artery
B. interosseous artery
C. vena cava
D. pulmonary artery - D. pulmonary artery
Most arteries in the body carry oxygen-rich blood away from the heart, but the pulmonary artery
carries oxygen-poor blood from the right ventricle of the heart to the lungs. The vena cava would
not be correct because it is not an artery, it is a vein and the question asks for an artery.
Chocolate cysts of the ovaries are attributed to ____.
A. menorrhagia
B. ectopic pregnancy
C. pelvic inflammatory disease
D. endometriosis - D. endometriosis
Endometriosis is a condition in which the tissue from the uterus (endometrium) grows in other
parts of the body, such as the ovaries or bowel. If a woman has endometrial tissue in her ovary,
the tissue bleeds and builds up over time, and as the blood ages it turns brown, hence the term
"chocolate cyst."
Which is not true of synovial joints?
A. They are found in the intervertebral discs of the spinal column
B. They have a fluid-filled capsule that surrounds their articulating surface
C. They are the most common joint in the body
D. They are the most moveable joint type in the body - A. They are found in the intervertebral
discs of the spinal column
Instead of a synovial joint, the intervertebral discs of the spinal column form a fibrocartilaginous
joint, which allows slight movement of the vertebrae of the spine.
