NSG 5544 EXAM 1 STUDY GUIDE QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTIONS | NEW UPDATE 2026 | SOUTH COLLEGE
Question 1
Which of the following is considered the primary risk factor for the development of Chronic
Obstructive Pulmonary Disease (COPD)?
A) High sodium diet
B) Sedentary lifestyle
C) Cigarette smoking
D) Viral infections
E) Obesity
Correct Answer: C) Cigarette smoking
Rationale: Smoking is the most significant risk factor for COPD, accounting for the vast
majority of cases. While environmental pollutants and alpha-1 antitrypsin deficiency are
also factors, tobacco smoke remains the leading cause of airway inflammation and alveolar
destruction.
Question 2
A patient presents with a chronic cough, sputum production, and progressive dyspnea. Which
physical exam finding would most likely suggest advanced COPD?
A) S3 gallop
B) Pleuritic chest pain
C) Barrel chest
D) Egophony
E) Xanthomas
Correct Answer: C) Barrel chest
Rationale: A barrel chest (increased anterior-posterior diameter) is a classic finding in
COPD, particularly emphysema. It occurs due to chronic air trapping and hyperinflation
of the lungs, which pushes the rib cage outward.
Question 3
What is the diagnostic gold standard for confirming a diagnosis of COPD?
A) Chest X-ray
B) Peak flow meter
C) Spirometry
D) Sputum culture
E) Arterial Blood Gas (ABG)
Correct Answer: C) Spirometry
Rationale: Spirometry is the required diagnostic tool to confirm airflow limitation. It
measures the volume of air an individual can inhale or exhale as a function of time.
Question 4
According to clinical guidelines, which spirometry result is diagnostic of COPD?
A) FEV1/FVC ratio > 0.80
, 2
B) FEV1/FVC ratio < 0.70
C) FEV1 increase of 15% post-bronchodilator
D) AHI > 5
E) ABI < 0.9
Correct Answer: B) FEV1/FVC ratio < 0.70
Rationale: A post-bronchodilator FEV1/FVC ratio of less than 0.70 confirms the presence of
persistent airflow limitation that is not fully reversible, which is the hallmark of COPD.
Question 5
A 65-year-old patient with COPD presents with increased dyspnea and change in sputum color.
What is the most common trigger for such an exacerbation?
A) Exercise
B) Cold weather
C) Respiratory infection
D) High salt intake
E) Allergic rhinitis
Correct Answer: C) Respiratory infection
Rationale: Exacerbations of COPD are most frequently triggered by respiratory tract
infections (viral or bacterial) and environmental pollutants. These triggers lead to
increased inflammation and mucus production.
Question 6
Which medication is considered a cornerstone for the long-term maintenance of COPD to reduce
symptoms and exacerbations?
A) Long-acting bronchodilators (LABA/LAMA)
B) Empiric antibiotics
C) High-dose aspirin
D) ACE inhibitors
E) Thiazide diuretics
Correct Answer: A) Long-acting bronchodilators (LABA/LAMA)
Rationale: Bronchodilators (SABA, LABA, and LAMA) are central to COPD symptom
management. Long-acting versions are preferred for maintenance therapy to keep airways
open and reduce the frequency of flare-ups.
Question 7
Community-Acquired Pneumonia (CAP) is most commonly characterized by which clinical
presentation?
A) Daytime sleepiness and morning headaches
B) Intermittent wheezing and chest tightness
C) Fever, productive cough, and pleuritic chest pain
D) Claudication and rest pain
, 3
E) Xanthomas and xanthelasma
Correct Answer: C) Fever, productive cough, and pleuritic chest pain
Rationale: The classic presentation of CAP includes acute onset of fever, a cough that often
produces sputum, and pleuritic chest pain caused by inflammation of the pleural lining.
Question 8
During a physical exam of a patient with suspected Community-Acquired Pneumonia (CAP), the
provider hears "E" to "A" changes during auscultation. What is this finding called?
A) Rhonchi
B) Wheezing
C) Egophony
D) S4 gallop
E) Bruit
Correct Answer: C) Egophony
Rationale: Egophony is a physical exam finding where the spoken "E" sounds like an "A"
through the stethoscope. It indicates lung consolidation, which is common in lobar
pneumonia.
Question 9
What is the typical finding on a chest X-ray for a patient diagnosed with Community-Acquired
Pneumonia (CAP)?
A) Flat diaphragm and hyperinflation
B) Lobar consolidation or infiltrates
C) Cavitary lesions in the upper lobes
D) Normal lung fields with a large heart
E) Kerley B lines
Correct Answer: B) Lobar consolidation or infiltrates
Rationale: Pneumonia causes the alveoli to fill with fluid or pus, appearing as white patches
(infiltrates) or solid blocks (consolidation) on a chest X-ray.
Question 10
Which of the following is an appropriate empiric antibiotic treatment for an outpatient with CAP
and no comorbidities?
A) Lisinopril
B) Azithromycin or Doxycycline
C) Varenicline
D) Albuterol
E) Warfarin
Correct Answer: B) Azithromycin or Doxycycline
Rationale: Guidelines often recommend macrolides (like azithromycin) or tetracyclines (like
