Blood flow through heart - CORRECT ANSWER✔✔deoxygenated blood
comes from the lung through the inferior and superior vena cava it
then goes into the right atrium through the valve into the right
ventricle, the blood is then pumped out through the pulmonary artery
to the lungs. Gas exchange happens in the lungs and then the
oxygenated blood comes back to the heart through the pulmonary
veins. The pulmonary veins bring oxygenated blood to the left atrium
and it passes through the valve into the left ventricle. The blood is
then pumped out into the body through the aorta.
Best position for performin high quality chest compressions -
CORRECT ANSWER✔✔: Supine on a rigid surface like on the ground or
on a backboard
How does Aspirin work - CORRECT ANSWER✔✔*Action:* Anti-
inflammatory agent and anti-fever agent; prevents platelets from
clumping, thereby decreasing formation of new clots
*Interactions:* Caution should be used in patients who are taking
anticoagulants
*Administration Concerns:* Do not administer for pain caused by
trauma or for fevers in children; patients with chest pain must be able
to chew tablets
*Dosage:* 160 to 325 mg
, Indications: Relief of mild pain, headache, muscle aches; chest pain of
cardiac origin
Contraindications: Hypersensitivity; recent bleeding
Large vessels, arteries, and veins - CORRECT ANSWER✔✔The superior
and inferior vena cava brings deoxygenated blood to the heart. The
aorta takes oxygenated blood to the body, it splits off into the carotid
arteries that bring blood to the brain, the subclavian arteries that go
along your clavicle, abdominal aorta that takes blood to the bottom of
your body, and the coronary arteries that provide blood supply to the
heart. The subclavian arteries turn into the brachial arteries once they
hit your upper arm, once the brachial is in your lower arm it turns into
the ulnar and radial artery. The abdominal aorta turns into your two
iliac arteries and then your femoral artery in your groin. After the groin
the femoral turns into the tibial and peroneal arteries. The peroneal
and tibial veins bring deoxygenated blood back up as they go up your
leg they turn into the femoral and great saphenous vein in the thigh
area. In the pelvis area the femoral and saphenous turn into the iliac
veins and the inferior vena cava. Coming from the hands the basilic
veins bring blood back to the cephalic vein which turns into the
subclavian vein. The subclavian then goes into the superior vena cava
and back to the heart. Coming from the brain the deoxygenated blood
flows through the jugular vein.
Understand all layers of the heart. Be able to identify - CORRECT
ANSWER✔✔*Pericardial Cavity* - is a fluid-filled cavity where the heart
sits within; between the two layers of serous pericardium around the
heart (parietal and visceral layers).
*Pericardium* - the membrane enclosing the heart, consisting of an
outer fibrous layer and an inner double layer of serous membrane. This
serous membrane produces serous fluid to lubricate the heart and
prevent friction between the beating heart and its surrounding organs.
Holds the heart in position and maintains a hollow space for the heart
to expand. Visceral layer covers the outside of the heart and the
parietal layer forms a sac around the outside of the pericardial cavity.
