What is the name for the amount of blood that is ejected from the heart with each beat?
- A.
Ejection Fraction
- B.
Cardiac Output
- C.
Minute Volume
- D.
Stroke Volume
Correct Answer
D. Stroke VolumeExplanation
Stroke volume refers to the amount of blood that is ejected from the heart with each beat. It is the difference between the volume of blood in the heart at the end of diastole (end-diastolic volume) and the volume of blood remaining in the heart at the end of systole (end-systolic volume). Stroke volume is an important measure of cardiac function and is used to calculate other parameters such as cardiac output.Rate this question:

What is the average amount of blood that is ejected from the heart over an entire minute?
- A.
4 - 5 Liters
- B.
70 milliliters
- C.
4 - 5 Galons
- D.
70 ounces
Correct Answer
A. 4 - 5 LitersExplanation
The average amount of blood that is ejected from the heart over an entire minute is 4 - 5 Liters. This is the correct answer because the average adult human has a blood volume of about 5 liters, and the heart pumps the entire volume of blood in the body through the circulatory system in one minute. Therefore, the average amount of blood ejected from the heart over a minute would be around 4 - 5 Liters.Rate this question:

During what stage of a cardiac cycle does the coronary arteries fill with blood?
- A.
Diastole
- B.
Systole
- C.
Coronary Phase
- D.
Phase III
Correct Answer
A. DiastoleExplanation
During diastole, the heart is in a relaxed state and the ventricles are filling with blood. This is the stage of the cardiac cycle when the coronary arteries fill with blood. The coronary arteries supply oxygenated blood to the heart muscle itself, allowing it to receive the necessary nutrients and oxygen for proper functioning.Rate this question:

When performed properly, most victims of cardiac arrest will make a full recovery.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false. When cardiac arrest occurs, the heart stops beating, and without immediate medical intervention, it can lead to death. While prompt CPR and defibrillation can improve the chances of survival, the outcome is not guaranteed, and many victims of cardiac arrest do not make a full recovery. Cardiac arrest is a serious medical emergency that requires immediate attention and professional medical assistance.Rate this question:

ROSC is an acronym for:
- A.
Return of some circulation.
- B.
Return of spontaneous circulation
- C.
Return of some cardiac
- D.
Rarely occuring super compressions
Correct Answer
B. Return of spontaneous circulationExplanation
ROSC stands for Return of Spontaneous Circulation. This term is commonly used in the medical field to describe the restoration of a patient's heartbeat and blood flow without any external intervention. It indicates that the patient's heart has started beating on its own again after a period of cardiac arrest or other similar conditions.Rate this question:

In general, when the body is sick or injured, the heart rate will
- A.
Decrease in an attempt to rest.
- B.
Remain the same as the heart is not affected by illness or injury.
- C.
Increase as oxygen demand increases.
- D.
Completely stop until the illness or injury is resolved
Correct Answer
C. Increase as oxygen demand increases.Explanation
When the body is sick or injured, the heart rate will increase as oxygen demand increases. This is because the body requires more oxygen to heal and fight off infections. The heart pumps oxygen-rich blood to the organs and tissues, and an increased heart rate ensures that an adequate supply of oxygen is delivered. This increase in heart rate helps to meet the body's increased metabolic demands during illness or injury.Rate this question:

Proper compression rate and depth is essential in order to pause longer between cycles in order to check a pulse.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement suggests that a proper compression rate and depth are necessary to pause longer between cycles to check a pulse. However, this is incorrect. In fact, it is crucial to maintain a continuous and uninterrupted compression rhythm during CPR. Pausing for an extended period can decrease the effectiveness of chest compressions and reduce blood flow to the vital organs. Therefore, the correct answer is false.Rate this question:

Chest compression will essentially squeeze the heart between the sternum and the
- A.
Lungs
- B.
Ribs
- C.
Backbone
- D.
Cervical vertabrae
Correct Answer
C. BackboneExplanation
When performing chest compressions during CPR, the sternum is pressed down towards the backbone. This action creates pressure on the heart, which in turn helps to pump blood throughout the body. Therefore, the correct answer is backbone, as it is the structure against which the sternum is compressed during chest compressions.Rate this question:

It essential to compress the chest as rapidly as possible in order to improve cardiac output.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Compressing the chest rapidly is not essential to improve cardiac output. While chest compressions are a crucial part of cardiopulmonary resuscitation (CPR), the speed at which they are performed is not the primary factor in improving cardiac output. The depth and quality of the compressions, along with proper ventilation, are more important in achieving effective CPR. Rapid chest compressions may be necessary in certain situations, but it is not the sole determinant of improving cardiac output.Rate this question:

Research has shown that compressions can be given consistently and effectively if done so in tandem with which popular 70's song?
- A.
Don't mess around with Jim
- B.
Fire and Rain
- C.
Hotel california
- D.
Staying Alive
Correct Answer
D. Staying AliveExplanation
Research has shown that compressions can be given consistently and effectively if done in tandem with the beat of the song "Staying Alive". The rhythm of the song has a tempo of around 100 beats per minute, which is the recommended rate for performing chest compressions during CPR. This popular 70's song has been widely used as a mnemonic device to help individuals maintain the correct rhythm and pace while administering CPR, ultimately increasing the chances of successful resuscitation.Rate this question:

Effective CPR is known to create a cardiac output that is
- A.
25 - 30% that of the heart on its own.
- B.
100% that of the heart on its own.
- C.
50% that of the heart on its own.
- D.
1 - 5% that of the heart on its own.
Correct Answer
A. 25 - 30% that of the heart on its own.Explanation
Effective CPR is known to create a cardiac output that is 25-30% that of the heart on its own. This means that CPR can generate a blood flow that is approximately one-fourth to one-third of what the heart is capable of pumping on its own. CPR helps to maintain circulation and oxygenation of vital organs during cardiac arrest when the heart is not functioning properly. While CPR is not as effective as the heart's natural pumping action, it can still provide a significant amount of blood flow to keep the body alive until advanced medical interventions can be administered.Rate this question:

Cell death will begin to occur after 10 minutes of being without oxygen.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Cell death will not begin to occur after 10 minutes of being without oxygen. While prolonged oxygen deprivation can lead to cell death, the exact time frame varies depending on factors such as the type of cells and the individual's overall health. In some cases, cells can survive for much longer than 10 minutes without oxygen before irreversible damage occurs. Therefore, the statement is false.Rate this question:

Effective CPR compression rate and compression depth is not the only important aspect of performing adequate CPR.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because while the compression rate and depth are crucial aspects of performing effective CPR, they are not the only important factors. Other factors such as proper hand placement, allowing for full chest recoil, minimizing interruptions in compressions, and providing adequate ventilation also contribute to the overall effectiveness of CPR. Therefore, focusing solely on compression rate and depth may not result in adequate CPR.Rate this question:

Performing CPR on an individual is likely to cause which of the following side effects?
- A.
Broken ribs
- B.
Vomiting
- C.
Distended abdomen
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Performing CPR on an individual can cause broken ribs due to the force applied during chest compressions. This is a common side effect as the sternum may crack or fracture under the pressure. Additionally, the forceful compressions can cause vomiting in the individual due to the stimulation of the gag reflex. Lastly, CPR can lead to a distended abdomen as the air that is being forced into the lungs during rescue breaths can also enter the stomach, causing it to expand. Therefore, all of the given options are potential side effects of performing CPR.Rate this question:

What do you call a fish with 2 knees?
- A.
Leg fish
- B.
Knee fish
- C.
A walking fish
- D.
A two knee fish
Correct Answer
D. A two knee fishExplanation
The correct answer is "A two knee fish" because the question is asking for the name of a fish with 2 knees. This answer directly states that it is a fish with two knees, which is the information being asked for. The other options, such as "Leg fish" and "Knee fish," do not specifically mention the number of knees the fish has. "A walking fish" is also not a direct answer to the question.Rate this question:
