NUR 6111 EXAM 2 MOST TESTED QUESTIONS AND
ANSWERS GRADED A+ WITH RATIONALES
1. When reading a TST (PPD), all of the following indicate a positive test except:
A. ≥5 mm induration in HIV-positive persons
B. ≥10 mm induration in recent immigrants
C. ≥15 mm induration in healthy low-risk individuals
D. Healthy
Answer: D. Healthy
Rationale: A “positive” PPD depends on risk factors and size of induration, not on health status alone.
2. An employee with latent TB has a positive TST and QFT but a clear CXR. Before starting INH therapy,
you should order which additional test?
A. Serum creatinine
B. Liver function tests (LFTs)
C. Complete blood count
D. HIV antigen
Answer: B. Liver function tests
Rationale: INH can cause hepatotoxicity, so baseline LFTs are essential.
3. What percentage of lung cancers is attributed to active cigarette smoking?
A. 50%
B. 70%
C. 90%
D. 100%
Answer: C. 90%
Rationale: Approximately 90 % of lung cancers are linked to tobacco exposure.
4. In a smoker with chronic cough, which finding most warrants a low-dose CT scan?
A. Occasional wheezing
B. Night sweats
C. Persistent cough or change in cough character
D. Intermittent chest tightness
,ESTUDYR
Answer: C. Persistent cough or change in cough character
Rationale: A new or changing chronic cough in a smoker prompts imaging to rule out malignancy.
5. All of the following are evidence-based smoking-cessation recommendations except:
A. Offer nicotine replacement therapy
B. Advise behavioral counseling
C. Prescribe varenicline or bupropion
D. Recommend against e-cigarettes
Answer: D. Recommend against e-cigarettes
Rationale: While not first-line, e-cigarettes may be considered harm-reduction tools when other
methods fail.
6. Which bacterial pathogen is not a common cause of acute bronchitis?
A. Mycoplasma pneumoniae
B. Bordetella pertussis
C. Chlamydophila pneumoniae
D. Pneumonia virus
Answer: D. Pneumonia virus
Rationale: Acute bronchitis is primarily viral; Pneumonia is a syndrome, not a bronchitic pathogen.
7. Which symptom does not typically occur in pneumonia?
A. Fever
B. Productive cough
C. Pleuritic chest pain
D. Altered mental status in healthy young adults
Answer: D. Altered mental status
Rationale: While AMS can occur in elderly or severe cases, it is not a “classic” symptom in otherwise
healthy adults.
8. The gold standard to confirm pneumonia diagnosis is:
A. Sputum Gram stain
B. Pulse oximetry
C. Chest radiograph (CXR)
D. Serum procalcitonin
, ESTUDYR
Answer: C. Chest radiograph
Rationale: Imaging demonstrates infiltrates and consolidations diagnostic of pneumonia.
9. Current guidelines recommend low-dose CT screening for high-risk lung-cancer patients starting at
age:
A. 45
B. 55
C. 65
D. 75
Answer: B. 55
Rationale: Annual screening is advised for 55–80 year olds with ≥30 pack-year smoking history who
currently smoke or quit within 15 years.
10. Asthma is best described as:
A. Acute infection of the bronchi
B. Primary pulmonary fibrosis
C. Chronic airway inflammation with superimposed bronchospasm
D. Irreversible airflow obstruction
Answer: C. Chronic airway inflammation with superimposed bronchospasm
Rationale: Asthma’s hallmark is reversible obstruction atop an inflammatory milieu.
11. All of the following are used to treat pulmonary embolism except:
A. Heparin
B. Low-molecular-weight heparin
C. Tissue plasminogen activator (tPA)
D. Clopidogrel (Plavix)
Answer: D. Clopidogrel
Rationale: Antiplatelets aren’t indicated for PE; anticoagulation or thrombolysis is standard.
12. The classic ECG finding in pulmonary embolism is:
A. ST-segment elevation V₂–V₄
B. T-wave inversion in lead III, an S wave in lead I, and Q wave in lead III (S1Q3T3)
C. Peaked P waves
D. Prolonged PR interval
