HONDROS NURSING 160 EXAM 2 UPDATED WITH MOST TESTED
QUESTIONS AND ANSWERS | GRADED A+ | ASSURED SUCCESS WITH
DETAILED RATIONALES
1. Which assessment finding is commonly associated with COPD?
A. Pitting edema
B. High-pitched wheezing
✅C. Barrel-shaped chest and digital clubbing
D. S3 heart sound
Rationale: COPD often presents with a barrel chest (due to lung hyperinflation) and clubbing of fingers
caused by chronic hypoxia.
2. Respiratory acidosis occurs when the body:
A. Loses too much CO₂
✅B. Retains CO₂, resulting in acidic blood pH
C. Retains bicarbonate
D. Over-breathes due to anxiety
Rationale: Elevated CO₂ from hypoventilation leads to acid accumulation in the blood, causing
respiratory acidosis.
3. What is the primary nursing intervention for respiratory acidosis?
A. Administer sodium bicarbonate
B. Begin IV fluids
✅C. Assist the patient with ventilation (e.g., oxygen or ventilator support)
D. Restrict fluid intake
Rationale: Enhancing ventilation helps eliminate excess CO₂ and restore normal pH.
4. The Glasgow Coma Scale (GCS) assesses:
A. Pupil response (PERRLA)
✅B. Eye opening, verbal response, and motor response to pain
C. Reflexes and gait
D. Vitals and skin color
, ESTUDYR
Rationale: GCS measures neurological responsiveness by evaluating eye, verbal, and motor responses—
not pupil reaction.
5. What distinguishes emphysema from COPD?
A. Emphysema is viral in origin
✅B. Emphysema is a subtype of COPD, most often caused by smoking
C. COPD only includes chronic bronchitis
D. Emphysema affects the airways only
Rationale: Emphysema is part of COPD caused primarily by smoking-induced alveolar damage.
6. When checking pulse oximetry at home, you should:
A. Place the sensor on cold fingers
✅B. Ensure warm extremities and avoid the arm with a BP cuff
C. Place it in direct sunlight
D. Apply nail polish for contrast
Rationale: Cold or compressed extremities (e.g., from BP cuff) can cause inaccurate readings.
7. For a focused respiratory assessment, the nurse should check:
A. History of allergy
✅B. O₂ device/settings, nasal cannula placement, respiratory rate, and pulse ox reading
C. Diet preferences
D. Activity level only
Rationale: These assess oxygen delivery and function of ventilation in respiratory patients.
8. Proper steps to draw an arterial blood gas (ABG) specimen include:
A. Use a 20 mL syringe and place at room temp
✅B. Use a 3–5 mL syringe, ice the specimen immediately, and send to the lab
C. Use a vacuum tube and process in an hour
D. Use EDTA tubes and refrigerate
Rationale: Immediate cooling preserves gas levels; delay or wrong handling invalidates results.
