EMT Cardiology Practice Test 2

Question 1

The normal heart rate for a newborn is:

Accepted Answer

140 – 160

Answer

Newborns have significantly higher resting heart rates compared to older children and adults due to their higher metabolic rate and smaller cardiac output per beat. A normal heart rate for a newborn typically ranges between 140 and 160 beats per minute, though it can vary slightly. This elevated rate is essential to meet their physiological demands.

Question 2

The normal heart rate for a child between the ages of 1-6:

Accepted Answer

100 – 120

Answer

Normal heart rates vary significantly with age. For children between 1 and 6 years old, their cardiovascular system is still developing, resulting in a faster resting heart rate compared to adults. The typical range for this age group is 100 to 120 beats per minute, reflecting their higher metabolic demands.

Question 3

The normal heart rate for a child over the age of 6 is:

Accepted Answer

80 – 100

Answer

As children mature past the age of 6, their cardiovascular system continues to develop, and their resting heart rate gradually decreases. For a child over 6 years old, the normal heart rate range typically falls between 80 and 100 beats per minute. This rate is closer to that of an adult as their body grows and metabolic demands stabilize.

Question 4

The correct flow of blood through the heart and lungs is…?

Accepted Answer

Inferior/superior vena cavae, right atrium, right ventricle, lungs, left atrium, left ventricle, aorta

Answer

Deoxygenated blood from the body enters the right atrium via the vena cavae, then flows into the right ventricle, which pumps it to the lungs for oxygenation. Oxygenated blood returns to the left atrium, moves into the left ventricle, and is then pumped out to the rest of the body through the aorta. This precise sequence ensures efficient circulation and oxygen delivery.

Question 5

What is the difference between angina pectoris and a myocardial infarction?

Accepted Answer

Angina pectoris is caused by physical or emotional stress

Answer

Angina pectoris is chest pain caused by temporary myocardial ischemia, often triggered by physical exertion or emotional stress, and typically relieved by rest or nitroglycerin. In contrast, a myocardial infarction (heart attack) involves permanent heart muscle damage due to prolonged ischemia, and its pain is usually not relieved by rest. This difference in cause and relief is a key distinguishing factor.
