Medical Surgical Bronchoscopy #1

Question

Which finding would the nurse expect to see on a normal bronchoscopy?

Answers

  1. Mucus plug in the bronchi.
    • Rationale:

      This answer is not correct because this is an abnormal finding with a bronchoscope. Other substances that are abnormally found on bronchoscopy include blood, stones, and foreign objects.

  2. Protruding cartilage of bronchial wall.
    • Rationale:

      This answer is not correct because this is a bronchial wall abnormality. Other bronchial wall abnormalities include inflammation, tumors, ulceration, and submucosal lymph node enlargement.

  3. Blood in the trachea.
    • Rationale:

      This answer is not correct because blood in the trachea is an abnormal finding. Blood in the trachea may indicate a neoplasm, hemangioma, or tracheal stenosis.

  4. Right bronchus larger than left.
    • Rationale:

      This answer is correct because the right bronchus is wider, shorter, and more vertical than the left. The right lung has three lobes, while the left only has two. This is why it is larger. The right lung is shorter, to accommodate the liver, which is tucked underneath the ribcage. The size of the left lung helps make room for the heart.

Overview

A bronchoscopy is a procedure that allows direct visualization of the larynx, trachea, and bronchi with a fiberoptic scope. Normal bronchoscopy findings include the bronchi is structurally the same with the trachea, right bronchus is slightly larger than the left, and a small bronchi branching from the main bronchi.
