Cardio Questions and Answers (Q&A)

The first type of circulation is the Pulmonary Circulation. This involves removing the oxygen-depleted blood cells from the heart going the lungs so that they would receive proper oxygen. The second type of circulation is the Systematic Circulation. This brings the blood cells with oxygen to be distributed to different parts of the body before going back to the heart.

The third type is the coronary circulation. It allows blood to be placed inside the heart. The last type of circulation is the one that happens in the heart itself. The heart is responsible for pumping blood to various parts of the body. These four types of circulation are very important to the human body.

The argument for standing vs. prone restraint has been debated. When suddenly standing, the pulse dramatically increases. Upon assuming the correct posture, blood tends to go to the vascular compartment of the lower extremities due to the effects of gravity, which reduces the stroke volume, resulting in a decrease in systolic blood pressure.

To ensure that rapid adjustments occur, your blood pressure is being maintained. A significant difference between standing versus supine blood pressure could indicate medical problems.

The correct answer here would be arrived at by dividing the total oxygen consumption by the arteriovenous oxygen gradient, according to what I could find on the internet about this kind of calculation.

Now, I’m not an expert in nursing or in these measurements, so I cannot tell you which measurements are needed out of what is given. If I look at the previous answer, they got 6.25 L/min, or answer D, and they used all of the measurements given.

In light of this, I am almost positive that answer D is the correct answer, especially as I have not found a calculator that asks for these specific measurements when calculating the cardiac output of a patient with the provided numbers.

B is the answer to this question. There are absent p waves and this is a sign that there is a problem with the atrium. The pacemaker should be applied in the atrioventricular also known as AV node. As per the given, the qrs and the t waves are normal.

This means the depolarization and repolarization should be done in a normal manner which can only be done if option B is chosen. Placing the pacemaker in the Purkinje system would make the ventricles become activated in an abnormal sequence. This should be avoided because even the qrs would follow an abnormal sequence.

The correct answer here is the left-to-right ventricular shunt, or answer C. This is because this particular kind of shut allows the blood to flow backwards in the heart.

The heart is an incredible organ because it keeps the blood flowing in one direct route through the heart. The blood has to follow the set route. If it doesn’t, a clot could form because of blood standing still.

When blood flows back into the pulmonary system instead of going out to deliver the oxygen rich blood, the pulmonary blood flow is greater than any other kind of blood flow in the body. This is quite the intriguing situation, but it needs to be fixed because the blood is not delivering oxygen properly.

The answer to this question is E. When the body starts to anticipate that the body is about to undergo exercise, the central command will increase sympathetic outflow to the blood vessels and the heart. This can make the heart rate increase and contract.

The other choices are meant for different purposes. It is important for people to do some exercising because it will surely improve their body overall. It will help increase their blood flow, increase their cardiac output, and at the same time have a healthier body that will allow them to live for a long time. Just take a few minutes to exercise every day and this will already make a lot of difference.
