Answer #1

Asthma lead due to hyperresponsiveness of bronchial muscles. In this disease due to secretion of inflammatory mediators, autocoids. a bronchial muscle spasm occurs which narrow the windpipe.

In gas exchange, the oxygen level gets stated decrease in lungs and carbon dioxide increase due to narrowing of bronchial muscles. Pulmonary ventilation also decrease. gases affected due to increasing carbon dioxide and decrease oxygen in the blood.

In normal breathing regulation, the respiratory center regulates smoothly. Where in asthma due to the bronchial spasm and lack of oxygen in body respiratory center look overactive. which increase the rate of breathing.

Hilda Wilde is a 45-year-old woman who was diagnosed with asthma as a child. She recalls her first asthma attack being horrendous; chest tightness, difficulty breathing, wheezing, feeling anxious and sweating profusely. She was rushed to hospital and spent many days in hospital as a child until she managed to work out the triggers and control it early. The triggers for her asthma were cold temperatures, pollen, smoky environments and respiratory infections/colds, which continue to be the triggers throughout her...

True/False The exchange of gas molecules from areas of higher concentration to areas of lower concentration is called osmosis. Oxygen and carbon dioxide exchange takes place in the alveoli. Cyanosis is a reliable and early sign of hypoxia. When a nurse documents that a patient is tachypneic, it indicates a respiratory rate greater than 24 breaths/minute. On assessment, the nurse would describe coarse crackles as discontinuous popping sounds heard in early inspiration. A serious complication of a group A beta-hemolytic...
