Respiratory (1–15)

1. A patient with COPD has an SpO₂ of 86%. What is the priority nursing action?

 A. Apply a non-rebreather mask at 15 L/min
 B. Start oxygen via nasal cannula at 2 L/min
 C. Position the patient prone
 D. Prepare for intubation

*In COPD, high oxygen can suppress the hypoxic drive. Start low (2 L/min) and titrate to
SpO₂ 88–92%.*

2. Which finding indicates a tension pneumothorax?

 A. Bilateral crackles
 B. Frothy sputum
 C. Tracheal deviation to the opposite side
 D. Decreased jugular venous distention

Tracheal deviation away from the affected side is a late sign of tension pneumothorax, a
life-threatening emergency.

3. A patient with asthma has a peak flow reading of 50% of personal best. What action
should the nurse take first?

 A. Administer albuterol via nebulizer
 B. Give oral prednisone
 C. Recheck in 30 minutes
 D. Encourage deep breathing

*50% indicates a moderate exacerbation; bronchodilator (albuterol) is first-line treatment.*

4. Which symptom differentiates left-sided heart failure from right-sided heart failure?

, A. Jugular vein distention
 B. Peripheral edema
 C. Crackles in lung bases
 D. Hepatomegaly

Crackles indicate pulmonary congestion, a hallmark of left-sided failure. JVD/edema = right-
sided.

5. The nurse notes a patient with pneumonia has new-onset confusion. What is the
priority action?

 A. Reorient the patient
 B. Notify the provider for a CT scan
 C. Assess oxygen saturation
 D. Increase IV fluids

Confusion in older adults with pneumonia often indicates hypoxemia. Assess oxygenation
first.

6. A patient with pulmonary embolism is on heparin. Which lab requires immediate
action?

 A. INR of 1.2
 B. aPTT of 98 seconds (normal 25–35)
 C. Platelets 180,000
 D. Hemoglobin 13.5

aPTT > 70 seconds (or > 2.5x normal) indicates bleeding risk. Hold heparin and notify
provider.

7. Which diet is appropriate for a patient with COPD?

 A. Low-carb, low-calorie
 B. Clear liquids only
 C. High-protein, high-calorie small meals
 D. Low-fat, high-fiber

COPD increases metabolic demand. High-protein, high-calorie small meals reduce dyspnea
during eating.

, 8. A patient with bacterial pneumonia is on droplet precautions. Which action is
correct?

 A. Place in negative-pressure room
 B. Wear surgical mask within 3 feet of patient
 C. Use N95 respirator for all care
 D. Keep door closed at all times

Droplet precautions require a surgical mask within 3 feet. N95 is for airborne (TB, COVID).

9. The nurse hears absent breath sounds on the left side after chest tube insertion.
What is the priority action?

 A. Clamp the chest tube
 B. Assess for tracheal deviation
 C. Increase suction
 D. Document as normal

Absent sounds could indicate reaccumulation of pneumothorax or tube dislodgement; check
for tracheal shift (tension pneumothorax).

10. Which vaccine is recommended annually for all patients with asthma?

 A. Pneumococcal
 B. Influenza
 C. Tdap
 D. Hepatitis B

Influenza can trigger severe asthma exacerbations; annual flu vaccine is key.

11. A patient with TB is started on rifampin. What teaching is essential?

 A. Avoid sunlight
 B. Urine/tears may turn orange-red
 C. Monitor for hearing loss
 D. Take with antacids

Rifampin causes harmless orange-red discoloration of body fluids. Reassure patient.

12. Which finding in a patient with asthma indicates status asthmaticus?

 A. Peak flow 80% of personal best
