Question

14 multiple choice 5 points coughing up blood - tinged sputum from a bronchial hemorrhage is known as: pulmonary embolus. hemoptysis. hemothorax. apnea. 15 multiple choice 5 points the rounded top of each lung is called the: parietal pleura. hilum. apex. visceral pleura. 16 multiple choice 5 points an irregular breathing pattern with a period of apnea followed by deep, labored breathing that becomes shallow, then apneic cheyne - stokes respiration. orthopnea. hyperpnea. dyspnea.

Explanation:

• Question 14: Hemoptysis is defined as coughing up blood - tinged sputum from a bronchial hemorrhage. A pulmonary embolus is a blockage in a pulmonary artery (usually by a blood clot). Hemothorax is the accumulation of blood in the pleural cavity. Apnea is a temporary cessation of breathing.
• Question 15: The apex is the rounded top of each lung. The parietal pleura is the outer layer of the pleura that lines the thoracic cavity. The hilum is the area on the medial surface of the lung where structures (such as bronchi, blood vessels) enter and exit the lung. The visceral pleura is the inner layer of the pleura that covers the lung surface.
• Question 16: Cheyne - Stokes respiration is an irregular breathing pattern with a period of apnea followed by deep, labored breathing that becomes shallow, then apneic again. Orthopnea is difficulty breathing when lying flat. Hyperpnea is increased depth and rate of breathing. Dyspnea is a general term for difficulty in breathing.

Answer:

1. B. hemoptysis
2. C. apex
3. A. Cheyne - Stokes respiration
