Q1 Question 1 of 85
A 68-year-old man with a 40-pack-year smoking history presents with chronic productive cough,
dyspnea on exertion, and wheezing. Spirometry reveals FEV1/FVC ratio of 0.58 and FEV1 of 55
percent predicted. The nurse recognizes that these findings are most consistent with which stage of
COPD according to GOLD guidelines?
A. Moderate COPD with FEV1 between 50 and 79 percent predicted
B. Mild COPD with FEV1 greater than or equal to 80 percent predicted
C. Severe COPD with FEV1 between 30 and 49 percent predicted
D. Very severe COPD with FEV1 less than 30 percent predicted
Correct Answer: A
Rationale:
An FEV1 of 55 percent predicted with an FEV1/FVC ratio below 0.70 classifies as moderate COPD (GOLD Stage 2),
which is defined by FEV1 between 50 and 79 percent predicted. Mild COPD requires FEV1 at or above 80 percent.
Severe COPD requires FEV1 between 30 and 49 percent. Very severe COPD is below 30 percent.
Q2 Question 2 of 85
A 72-year-old woman with advanced emphysema has a barrel chest, uses accessory muscles to
breathe, and demonstrates pursed-lip breathing. The nurse explains that the primary physiological
benefit of pursed-lip breathing for this patient is which mechanism?
A. Increasing respiratory rate to improve oxygen saturation rapidly
B. Maintaining positive airway pressure during exhalation to prevent airway collapse
C. Decreasing inspiratory time to reduce the work of breathing
D. Shifting to mouth breathing to bypass nasal airway resistance
Correct Answer: B
Rationale:
Pursed-lip breathing creates back-pressure in the airways during exhalation, maintaining positive pressure that
prevents premature collapse of small airways and allows more complete emptying of the lungs. It does not increase
respiratory rate or shift to mouth breathing. The technique prolongs exhalation rather than decreasing inspiratory time.

, Q3 Question 3 of 85
A 65-year-old patient with COPD is receiving oxygen at 6 L/min via nasal cannula and becomes
increasingly drowsy with shallow respirations. Arterial blood gases reveal PaCO2 of 68 mmHg and
PaO2 of 78 mmHg. The nurse recognizes that this patient's condition is most likely caused by which
mechanism?
A. Pulmonary embolism producing sudden ventilation-perfusion mismatch
B. Anxiety and panic causing hyperventilation and respiratory alkalosis
C. Oxygen-induced hypoventilation from suppression of the hypoxic drive
D. Pneumothorax creating collapse of the unaffected lung
Correct Answer: C
Rationale:
In COPD patients who retain CO2, the respiratory drive may become dependent on hypoxemia rather than CO2 levels,
and high-flow oxygen suppresses this hypoxic drive, leading to hypoventilation and dangerous CO2 retention as
demonstrated by the elevated PaCO2. Anxiety would cause hyperventilation with low CO2. Pulmonary embolism and
pneumothorax present with acute dyspnea, not progressive drowsiness.
Q4 Question 4 of 85
A 70-year-old man with COPD is prescribed tiotropium bromide via dry powder inhaler. The nurse
should teach the patient that this medication works through which mechanism of action?
A. Short-acting beta-2 agonist causing rapid bronchodilation for acute relief
B. Methylxanthine derivative stimulating respiratory center drive
C. Inhaled corticosteroid reducing airway inflammation and mucus production
D. Long-acting anticholinergic producing sustained bronchodilation over 24 hours
Correct Answer: D
Rationale:
Tiotropium is a long-acting anticholinergic (LAMA) that blocks muscarinic receptors in airway smooth muscle, providing
sustained bronchodilation for 24 hours with once-daily dosing. Short-acting beta-2 agonists like albuterol provide rapid
relief but last only 4-6 hours. Inhaled corticosteroids reduce inflammation but do not directly cause bronchodilation.
Methylxanthines like theophylline are systemic agents with a different mechanism.
