Advanced Pleural Pathophysiology And Thoracic Intervention Protocols Practice Tests

Question 1

According to Boyle's Law, what happens to the pressure within the thoracic cavity during inspiration when the volume of the cavity increases?

Accepted Answer

The pressure decreases

Answer

The pressure increases

Answer

The pressure remains constant

Answer

The pressure becomes equal to atmospheric pressure

Question 2

Which type of pneumothorax is characterized by a one-way valve mechanism where air enters the pleural space but cannot exit, leading to mediastinal shift and impaired venous return?

Accepted Answer

Tension pneumothorax

Answer

Open pneumothorax

Answer

Closed pneumothorax

Answer

Spontaneous pneumothorax

Question 3

A closed pneumothorax is typically caused by the rupture of subpleural blebs on the visceral pleura.

Accepted Answer

True

Answer

False

Question 4

What is the primary pathophysiological mechanism of an open pneumothorax?

Accepted Answer

Air enters the pleural space through a defect in the chest wall during inspiration

Answer

Rupture of internal lung tissue due to high airway pressure

Answer

Accumulation of lymphatic fluid in the pleural space

Answer

Blood accumulation resulting from intercostal vessel trauma

Question 5

What is the medical term for the presence of lymphatic fluid in the pleural space, often resulting from thoracic duct interruption?

Accepted Answer

Chylothorax

Question 6

Which of the following are potential management strategies for a patient diagnosed with a chylothorax?

Answer

Octreotide administration

Answer

Pleurodesis

Answer

Immediate surgical resection of the lung

Answer

Hyperbaric oxygen therapy

Question 7

A patient presents with a hemothorax following blunt chest trauma. Which anatomical structures are most commonly the source of this blood accumulation?

Accepted Answer

Option A

Answer

Option B

Answer

Option C

Answer

Option D

Question 8

In a standard three-chamber chest drainage system, what is the primary purpose of the water seal chamber?

Accepted Answer

To act as a one-way valve that allows air to escape the pleural space while preventing air from re-entering.

Answer

To regulate the amount of suction applied to the patient.

Answer

To collect fluid drainage from the pleural space.

Answer

To measure the exact volume of air lost per minute.

Question 9

What is the correct nursing action if a patient with a chest tube exhibits subcutaneous emphysema (crepitus) around the insertion site?

Accepted Answer

Assess the extent of the swelling and notify the healthcare provider.

Answer

Apply a warm compress to the area to increase circulation.

Answer

Remove the chest tube immediately to stop the air leak.

Answer

Increase the suction pressure to pull the air out of the tissues.

Question 10

When managing a patient with an open sucking chest wound, the occlusive dressing should be taped on all four sides to ensure a complete airtight seal.

Accepted Answer

False

Answer

True

Question 11

Which of the following are essential components of the 'start of shift' nursing assessment for a patient with a chest tube? (Select all that apply)

Answer

Checking the insertion site for signs of infection or subcutaneous emphysema.

Answer

Recording the amount and character of the drainage.

Answer

Assessing the patient's pain level.

Answer

Removing the dressing to inspect the pleural cavity directly.

Question 12

What is the standard recommended suction level for the suction control chamber in a typical three-chamber drainage system?

Accepted Answer

20 cm H2O

Answer

5 cm H2O

Answer

10 cm H2O

Answer

50 cm H2O

Question 13

What is the immediate clinical priority if a chest tube becomes completely dislodged from the patient's chest?

Accepted Answer

Apply a sterile occlusive dressing and secure it on three sides.

Question 14

Why must the chest drainage system always be kept below the level of the patient's chest?

Accepted Answer

To prevent backflow of drainage fluid into the pleural space due to gravity.

Answer

To ensure the suction control chamber bubbles correctly.

Answer

To make it easier for the nurse to read the drainage levels.

Answer

To keep the tubing from becoming kinked.

Question 15

Which of the following is a critical distinction in the management of chest tubes between cardiac and pulmonary surgery patients?

Accepted Answer

Chest tubes in cardiac surgery are often milked to prevent tamponade, while those in lung surgery are generally not milked.

Answer

Chest tubes in lung surgery require constant milking to ensure lung re-expansion, while cardiac tubes must remain static.

Answer

Cardiac surgery chest tubes always exhibit significant respiratory fluctuations, whereas pulmonary tubes do not.

Answer

Both cardiac and pulmonary chest tubes must be milked every hour to maintain patency.

Question 16

In the post-operative period following cardiac surgery, it is expected that chest tubes will show significant respiratory fluctuations.

Accepted Answer

False

Answer

True

Question 17

Which clinical complication is the primary concern when chest tubes become obstructed following a Coronary Artery Bypass Graft (CABG)?

Accepted Answer

Cardiac tamponade

Answer

Pneumothorax

Answer

Pleural effusion

Answer

Mediastinitis

Question 18

Which of the following are essential components of pre-operative nursing care for a patient scheduled for cardiothoracic surgery?

Answer

Obtaining baseline ABGs

Answer

Teaching splinting techniques

Answer

Instruction on incentive spirometry use

Answer

Immediate post-operative ambulation

Question 19

What is the recommended frequency for post-operative ambulation to facilitate recovery in cardiothoracic surgery patients?

Accepted Answer

3-4 times daily

Answer

Once daily

Answer

Twice daily

Answer

Every 6 hours

Question 20

What is the primary goal of effective pain management in the immediate post-operative period for a patient who has undergone a thoracotomy?

Accepted Answer

To prevent hypoventilation
