Answer:

The correct answer is : D. isoelectric line.

Explanation:

ECG interpretation requires the analysis of various waves and curves and their characteristic.  There are different type of waves and curves that can be found and analyzed in ECG such as P- wave, T wave, PR interval and others.

All these curves and interval shows electrical activities generating by the repolarization and depolarization of atria and ventricles of heart.

Base line or isoelectric line shows a flat line which have no electric activity as there is no negative or positive charge to create deflection.

Thus, the correct answer is : D. isoelectric line.

A 52-year-old man presents to your office for an acute visit because of coughing and shortness of breath. He is well known to yo
Finger [1]

Answer:

The most likely cause of this patients dyspnoea is chronic bronchitis due to  his history of chronic smoking and the recent production of green phlegm with an increased mucus production

Therapy is generally focused on alleviation of symptoms.Toward this goal, a doctor may prescribe a combination of medications that open obstructed bronchial airways and thin obstructive mucus so that it can be coughed up more easily. Care for acute bronchitis is primarily supportive and should ensure that the patient is oxygenating adequately. Bed rest is recommended.

Acute treatment for the patient would be therapy with short-acting agonists or anticholinergic bronchodilators if there is acute exacerbation to help dilate the bronchioles and reduce inflammation. Additionally a short course of systemic corticosteroid therapy to aid with inflammation reduction and allow phlegm to be coughed up more easily

The most helpful intervention to help prevent future exacerbation is the avoidance of environmental irritants, especially cigarette smoke. and reducing the amount of smoking per day this will help control cough and sputum production in patients with chronic bronchitis
