Mrs. Helms was very upset with the news of her husband. condition. As the day progressed, she noticed that Mr. Helm's breathing was increasingly difficult. He could barely speak without losing his breath. Mrs. Helms called the nurse to her husband's, room. "My husband can't breathe! What is wrong? I thought he had a heart attack not a respiratory condition!" Nurse Nan auscultator the patient's chest listening to Mr. Helm's respirations, which were rapid and wet, producing or crackling sounds. Nurse Nan calmly informed Mrs. Helms, "I'm sorry. Your husband's condition is worsening. The damage to his heart it causing his respiratory problems." The left side of the heart receives blood from which part of the body? If the bicuspid (mitral) valve is not fully dosing, does pulmonary circulation increase, decrease, or not change? Does pulmonary blood pressure increase or decrease with left-sided heart failure? Does this change in pulmonary blood pressure increase or decrease capillary filtration in the lungs? Explain. How does change in pulmonary blood pressure and capillary filtration cause Mr. Helms' rales (wet breath sounds)? Why is Mr. Helms breathing rapidly?
Solution -
The condition of Mr. Helm signifies that the pulmonary pressure increases in the pulmonary arteries. This condition is known as pulmonary hypertension which commonly occurs when the left side of the heart stops functioning or it fails. The blood not pumped by the left heart is pumped back into the lungs thereby increasing the blood pressure. The heart do not get time to relax in this conditions due to continuous pumping back and fro.
Given: Time: 3.5 hrs Velocity: 120 miles/hour Now Distance= Speed x Time Now Velocity and Speed have the same magnitude. Velocity being a vector quantity has a definite direction. Where as speed is a scalar quantity, it indicates only the magnitude and doesn’t define any direction. Hence Distance= Velocity x Time Distance= 3.5x20=420 miles
