(Latest 2025 / 2026) Advanced Pathophysiology | Questions & Answers| 100% Correct | Grade A - Chamberlain

Question:

A patient with normal lungs should be able to exhale _____ of the forced vital capacity within the first second.

• 50%
• 70%
• 80%
• 90%

Answer:

80%

Question:

Simple spirometry includes a measure of residual capacity.

• True
• False

Answer:

False 1 / 4

Question:

The NP reviews the results of a patient's pulmonary function tests and notes that the FEV1, FVC, and total lung capacity (TLC) are reduced. The FEV1/FVC

ratio is normal. Based on interpretation, this reflects:

• Obstructive lung disease.
• Combined obstructive-restrictive lung disease.
• Restrictive lung disease.
• The test is invalid.

Answer:

Restrictive lung disease.

Question:

Chronic bronchitis will decrease which of the following parameters?

• Decreased total lung capacity.
• Decreased forced expiratory flow (FEV1).
• Increased lung compliance.
• Decreased diffusing capacity.

Answer:

Decreased forced expiratory flow (FEV1).

• / 4

Question:

Which of the following would indicate obstructive lung disease?

• Chronic asthma.
• Pneumonia.
• Pulmonary fibrosis.
• Pulmonary hypertension.

Answer:

Chronic asthma.

Question:

Which of the following spirometry results indicate restrictive lung disease?

a. FEV1, FEV, and total lung capacity normal: FEV1/FVC ratio normal.

• FEV1 reduced, FVC normal, total lung capacity reduced; FEV1/FVC ratio

normal.

• FEV1, FVC, and total lung capacity reduced; FEV1/FVC ratio normal.
• FEV1, FEV, and total lung capacity reduced; FEV1/FVC ratio reduced.

Answer:

FEV1, FVC, and total lung capacity reduced; FEV1/FVC ratio normal.

• / 4

Question:

The NP notes that a patient's FEV1/FVC ratio is normal. Which of the following conditions is most likely the patient's pulmonary issue?

• Pneumonia.
• Chronic asthma.
• Emphysema.
• Pulmonary fibrosis.

Answer:

Pulmonary fibrosis.

Question:

A patient with chronic bronchitis is most likely to experience:

• Respiratory alkalosis due to inability to exhale CO2.
• Respiratory acidosis due to decreased intake of O2.
• Respiratory acidosis due to inability to exhale CO2.
• Respiratory alkalosis due to inability to exhale CO2

Answer:

Respiratory acidosis due to inability to exhale CO2.
