Question 1

Which of the following best describes the pathophysiology of Chronic Obstructive Pulmonary Disease (COPD)?

Accepted Answer

COPD involves chronic inflammation leading to narrowing of airways, increased mucus production, and destruction of alveolar walls.

Question 2

A patient with COPD presents with a hematocrit (PCV) of 28%. The normal range is 40.00-54.00%. What does this finding most likely indicate?

Accepted Answer

Decreased oxygen-carrying capacity, possibly due to anemia.

Question 3

Which of the following is a common side effect of bronchodilator therapy in COPD management?

Accepted Answer

Tachycardia and tremors

Question 4

A 73-year-old male farmer is admitted with recurrent coughing episodes, blood in sputum, and difficulty breathing for 7 days. Which investigation would best help confirm a diagnosis of COPD?

Accepted Answer

Chest X-ray and spirometry

Question 5

Which of the following is NOT a typical sign or symptom of COPD?

Accepted Answer

Night sweats

Question 6

A patient with COPD has a blood sugar (random) of 163.00 mg/dl (normal: 70-140 mg/dl). Which medication listed in the case study could contribute to this finding?

Accepted Answer

Corticosteroids

Question 7

Which of the following best explains why patients with COPD often experience wheezing?

Accepted Answer

Bronchial walls become thickened and mucus plugs the airway, causing turbulent airflow.

Question 8

Which equation best represents the calculation of Body Mass Index (BMI), which is important in assessing nutritional status in COPD patients?

Accepted Answer

$$BMI = \frac{weight\ (kg)}{$$height^2$$\ (m^2$)}$$

Question 9

A patient with COPD is prescribed Rabecip (rabeprazole), a proton pump inhibitor. What is the primary reason for this medication in COPD management?

Accepted Answer

To reduce gastric irritation caused by frequent coughing and medication side effects.

Question 10

Which of the following lifestyle modifications is most important for a patient with COPD?

Accepted Answer

Smoking cessation

Question 11

Which anatomical structure is responsible for the exchange of gases in the lungs?

Accepted Answer

Alveoli

Question 12

A patient with COPD has a decreased RBC count of 3.25 million/cmm (normal: 4.20-6.50 million/cmm). What is the most likely consequence of this finding?

Accepted Answer

Decreased oxygen-carrying capacity, leading to fatigue and weakness

Question 13

Which of the following is a risk factor for developing COPD according to the case study?

Accepted Answer

Crowded living conditions

Question 14

Which of the following best describes the function of the diaphragm in respiration?

Accepted Answer

It contracts and flattens to increase thoracic volume, allowing air to enter the lungs.

Question 15

Which of the following laboratory findings is most consistent with inflammation in a COPD patient?

Accepted Answer

Increased neutrophil percentage (e.g., 72%)

Question 16

A patient with COPD is experiencing cyanosis. What does this indicate about the patient's oxygenation status?

Accepted Answer

Decreased oxygen saturation in the blood

Question 17

Which of the following is the most appropriate nursing intervention for a COPD patient experiencing shortness of breath?

Accepted Answer

Place the patient in a semi-Fowler's position to facilitate breathing

Question 18

Which of the following best explains why smoking cessation is critical in the management of COPD?

Accepted Answer

Smoking causes chronic inflammation and damage to airway and alveolar walls.

Question 19

Which of the following is a common complication of untreated COPD?

Accepted Answer

Pulmonary hypertension

Question 20

Which formula would you use to calculate the respiratory rate if you count 22 breaths in 30 seconds?

Accepted Answer

$$Respiratory\ Rate = Number\ of\ breaths\ in\ 30\ sec 	imes 2$$
