✔✔Bracytherapy is used to treat what? - ✔✔Cancer.
Bracytherapy is a type of radiation therapy. It is used to treat cancer. It uses ionizing
radiation. It is also known as internal radiation therapy
✔✔Of the following, which would be considered a minor reaction to contrast?
a. Laryngeal edema
b. Cimetidine
c. Bronchospasm
d. Vasovagal Syncope - ✔✔Vasovagal syncope.
Vasovagal syncope is fainting. It is important to monitor the patient's pulse, BP, oxygen
saturation and ECG. Also, the patient's legs should be elevated. IV access should be
established and atropine 0.6-1.2 mg administered for bradycardia. For persistent
hypotension, volume expansion with IV fluids is necessary.
✔✔Which of the following is a blood subsystem of the circulatory system?
,a. Straight circulation
b. Arterial circulation
c. Horizontal circulation
d. Pressure circulation. - ✔✔Arterial circulation
The circulatory system is composed of 4 subsystems. They are arterial circulation,
venous circulation, capillary circulation, and pulmonary circulation. The arterial
circulation includes arteries. Arteries that are in good health are both elastic and strong.
Arteries will narrow between each heartbeat. Arteries branch into arterioles. Arterioles
are smaller blood vessels.
✔✔Where are the largest veins in the body found?
a. Right side of the heart
b. Left side of the heart
c. Legs
d. Stomach - ✔✔Right side of the heart
The heart is considered a muscular organ. It is approximately the size of a human fist.
The heart is found behind and just a little bit to the left of the breastbone. The job of the
heart is to pump blood throughout the cardiovascular system. Some arteries and veins
in the circulatory system are connected to the heart directly. The veins found on the
right side of the heart are the largest in the body.
✔✔The IV dose for Odansetron as a conscious sedation is 4 mg, repeat x 1 if
necessary. What is the duration time?
a. 3-4 hrs
b. 45 mins
c. 4-8 hrs
d. 15 mins - ✔✔c. 4-8 hrs
Odansetron is an Antiemetic. For the average adult, the proper IV dose is 4 mg, repeat
x 1 if necessary.
✔✔What is the typical frame rate (frames per second) for the Anteroposterior calf
vessels view of a lower limb angiogram? - ✔✔1 frame per sec
For the Anteroposterior calf vessels view of a lower limb angiogram, the typical
parameters are:
Contrast volume (mL): 10 - 20
Injection rate (mL/s): 5
Frame rate (frames per second): 1
Field size (cm): 40
Inject delay (s): 0
X-ray delay (s): Increase as necessary
,✔✔Intracoronary brachytherapy uses a catheter that is directed into which part of the
heart?
a. The left atrium
b. The right ventricle
c. The coronary arteries
d. The vena cava - ✔✔c. The coronary arteries.
Brachytherapy typically focuses on issues in the coronary arteries, such as tissue
overgrowth of a stent or a blockage. To deliver specific doses of radiation, a special
heart catheter is directed into artery using x-ray guidance. The catheter is placed across
the blockage or tissue in the artery and targeted to the problem area and then removed
once it is complete.
✔✔What is performed before the pericardiocentesis?
a. nothing
b. 2-D echo
c. Xray
d. 3-D echo - ✔✔b. 2-D echocardiogram.
A 2-D echocardiogram may be performed before a pericardiocentesis. This will help
provide information about the perfusion.
✔✔Which of the following is a way to keep the coronary artery healthy?
a. Limit cholesterol in the diet
b. Increase cholesterol in the diet
c. Limit the diet to only liquids
d. Take higher doses of vitamins than recommended - ✔✔a. Limit cholesterol in the diet
The coronary artery brings blood to the heart. If the artery narrows it causes a lack of
blood flow to the heart. This is the major problem with coronary arteries. The most
common cause of this is cholesterol deposits. These deposits build up, creating blood
flow problems. To help keep the coronary artery healthy, cholesterol intake should be
limited.
✔✔What is gas exchange? - ✔✔Where blood gathers more oxygen and removes
carbon dioxide into the lungs
Capillaries are small blood vessels. Once blood makes it to the lungs, it then travels
through capillaries. In the capillaries, blood gathers more oxygen. The capillaries also
transfer carbon dioxide to the lungs. This is known as gas exchange.
✔✔What central alpha-agonist has a usual dose range of 0.2 - 1.2 mg?
a. Clonidine hydrochloride
b. Guanabenz acetate
c. Guanfacine hydrochloride
, d. Methyldopa. - ✔✔a. Clonidine hydrochloride (2-3 times per day)
✔✔A proximal embolic protection device seals ______ of the lesion. - ✔✔Distal.
The proximal occlusion/aspiration system seals distal of the lesion. This is upstream of
the lesion.
✔✔Before a pulmonary angiography, patients should do what? - ✔✔Not drink or eat
anything 6-8 hours prior to the test
Before a pulmonary angiography can begin, preparation is needed on the patient's part.
The patient should not drink or eat anything 6-8 hours prior to the test. The body needs
to be cleansed of food and drink to have a clearer picture.
✔✔Brachytherapy is also known as what? - ✔✔Internal radiation therapy.
Brachytherapy is a type of radiation therapy. It is used to treat cancer. It uses ionizing
radiation. It is also known as internal radiation therapy.
✔✔During a pulmonary angiography, once the x-rays are done, what can happen? -
✔✔The catheter can be removed
Pulmonary angiographies are used to check how well blood is flowing through the
lungs. After a catheter is properly placed, dye is injected and an X-ray is performed.
After this step, the catheter can be removed, and pressure should be placed on the cut.
✔✔AEDs use built in computers to do what? - ✔✔Check if defibrillation is necessary
AED stands for Automated External Defibrillator. This device is portable and lightweight.
It is used to give an electric shock to the heart. The AED can correct an irregular heart
rhythm and return the heart rhythm back to normal in a case of a sudden cardiac arrest.
They are used by checking if defibrillation is necessary. If necessary, a shock button will
be pressed giving the heart a shock.
✔✔What is used to treat arrhythmias?
a. Temporary pulse generator
b. Doppler pulse unit
c. ACT unit
d. Pacemaker - ✔✔d. Pacemaker
Pacemakers are small medical devices. They are used to help control heart rhythms
that are abnormal. Pacemakers use electrical pulses to control the heart beat, and
make it beat normally. Arrhythmias uses a pacemaker because the condition causes the
heart to beat either too slow, too fast, or irregularly.
✔✔An IVUS looks at what? - ✔✔Blood vessels.
