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 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.
Correct Answer is A
Explanation
A pulmonary embolism (PE) occurs when a blood clot, typically originating from the deep veins of the legs or pelvis, travels through the bloodstream and lodges in one of the pulmonary arteries in the lungs.
Deep venous thrombosis (DVT) is the most common source of pulmonary emboli. DVT occurs when a blood clot forms in the deep veins of the legs, pelvis, or arms, and can develop due to prolonged immobility, surgery, trauma, cancer, pregnancy, hormone therapy, or genetic factors.
Endocarditis, valvular heart disease, and left heart failure are not typical sources of pulmonary emboli. Endocarditis is an infection of the heart valves and lining, which can lead to valve damage and heart failure, but does not usually cause blood clots. Valvular heart disease, which includes conditions such as aortic stenosis and mitral regurgitation, can cause blood flow disturbances and increase the risk of thrombosis, but does not directly cause blood clots. Left heart failure, which occurs when the left ventricle of the heart is unable to pump effectively, can cause fluid buildup in the lungs, but does not typically cause blood clots to form.
