A patient is diagnosed with pulmonary disease and elevated pulmonary valvular resistance. Which of the following heart failures may result from this condition?
Left heart failure
Low output failure
High output failure
Right heart failure
The Correct Answer is D
Elevated pulmonary valvular resistance refers to a condition where there is increased resistance to blood flow through the pulmonary valve and into the lungs. This can lead to an increase in pressure within the right ventricle of the heart, which can eventually lead to right heart failure.
Right heart failure occurs when the right ventricle of the heart is unable to pump blood effectively, which can result in symptoms such as fatigue, shortness of breath, and fluid retention in the legs and abdomen. Causes of right heart failure include pulmonary hypertension, chronic obstructive pulmonary disease (COPD), pulmonary embolism, and other conditions that increase pressure within the pulmonary circulation.
Left heart failure, on the other hand, occurs when the left ventricle of the heart is unable to pump blood effectively, which can lead to symptoms such as shortness of breath, fatigue, and fluid retention in the lungs and legs. Causes of left heart failure include coronary artery disease, hypertension, and valvular heart disease.
Low output failure occurs when the heart is unable to pump enough blood to meet the body's needs, and can result from a variety of conditions affecting the heart muscle or heart valves. High output failure occurs when the heart is working harder than normal to meet the body's demands, such as in conditions such as hyperthyroidism or severe anemia

Correct Answer is C
Explanation
Atherosclerosis is a condition where the walls of the arteries become thick and hard due to the accumulation of fatty deposits, cholesterol, and other substances. Over time, these deposits can build up and narrow the arteries, reducing blood flow to the heart muscle. This can lead to the development of coronary artery disease, which is a condition where the heart muscle does not get enough oxygen and nutrients to function properly. The narrowing of the arteries can also increase the risk of blood clots, which can lead to a heart attack or stroke.
Myocarditis is an inflammation of the heart muscle, usually caused by a viral infection, and is not the most common cause of coronary artery disease.
Hypoglycemia is a condition where the blood sugar level is too low, and it is not directly related to the development of coronary artery disease.
Vasospasm is a sudden constriction of a blood vessel, which can lead to reduced blood flow and tissue damage. It can contribute to the development of coronary artery disease, but it is not the most common cause.
Correct Answer is D
Explanation
Tachycardia refers to a heart rate that is faster than the normal range, which is typically considered to be between 60 and 100 beats per minute in adults. A heart rate of 110 beats per minute is above the normal range and is considered tachycardia.
