Practice Exam with Answers &
Rationales
### RESPIRATORY SYSTEM (Questions 1-50)
**1. A client with chronic bronchitis often shows signs of hypoxia.
Which of the following is the priority to monitor for in this client?**
A. O2 levels
B. Barrel chest
C. Nutritional Status
D. Clubbing of fingers
**Answer: A. O2 levels**
*Rationale:* In chronic bronchitis, hypoxia is a primary concern due to
chronic inflammation and mucus production obstructing airways.
,Monitoring oxygen saturation is the priority to prevent complications
like respiratory failure. Barrel chest and clubbing are late findings, while
nutritional status is important but not the priority .

**2. Which of the following positions offers NO benefit to relieve
dyspnea in a client with chronic airflow limitation?**
A. Sitting at the edge of the chair, leaning forward with arms folded and
resting on a table
B. Low semi-reclining positions with shoulders back and neck apart
C. Leaning forward in a chair with feet spread apart and elbows placed
on knees
D. Upright with head slightly flexed, feet spread apart, and shoulders
relaxed
**Answer: B. Low semi-reclining positions with shoulders back and
neck apart**
*Rationale:* The tripod position (A, C, D) helps relieve dyspnea by
allowing accessory muscles to assist with breathing. A low semi-
reclining position does not provide the same mechanical advantage and
may actually impede diaphragmatic movement .
---
,**3. The nurse knows that which test is NOT used to identify potential
tuberculosis?**
A. Sputum culture
B. Chest x-ray
C. Mantoux skin test
D. Saliva swab
**Answer: D. Saliva swab**
*Rationale:* TB diagnosis requires sputum specimens, not saliva.
Sputum culture is the gold standard. Chest x-ray shows pulmonary
changes, and the Mantoux test indicates exposure. Saliva is not
appropriate for TB testing .

**4. A nurse has identified a nursing diagnosis of ineffective airway
clearance with bronchospasms for a client with pneumonia. What
nursing intervention will help conduct effective airway clearance?**
A. Increase liters of humidified oxygen
B. Scheduled and PRN albuterol nebulizer bronchodilator treatment
C. Handheld bronchodilator always as needed
D. Prednisone via inhaler or IV to reduce inflammation
, **Answer: B. Scheduled and PRN albuterol nebulizer bronchodilator
treatment**
*Rationale:* Albuterol is a bronchodilator that directly addresses
bronchospasm by relaxing smooth muscle. Scheduled and PRN dosing
ensures consistent airway opening. Oxygen alone doesn't clear airways,
and prednisone addresses inflammation but not acute bronchospasm .

**5. The nurse is teaching a client about post-rhinoplasty care. Which
statements indicate understanding? (Select All That Apply)**
A. I will have a very large dressing on my nose
B. I may have a very dry mouth and throat
C. There will be swelling that will cause a loss of sense of smell
D. I will have bruising around my eyes, nose, and face
E. I should limit coughing, sneezing, and blowing my nose
**Answer: B, D, E**
*Rationale:* B: Mouth breathing post-op causes dryness. D: Bruising
(raccoon eyes) and facial swelling are expected. E: Coughing/sneezing
increases pressure and bleeding risk. A: Dressing is typically small, not
