Section 1: Respiratory Disorders and Tuberculosis
(Questions 1-50)
1. A client is admitted with suspected tuberculosis. Which
precautions should the nurse implement?
A. Standard precautions only
B. Droplet precautions
C. Contact precautions
D. Airborne precautions
Answer: D
Rationale: Tuberculosis requires airborne precautions, which include a negative
pressure room, N95 respirator (or higher level), and appropriate personal protective
equipment . Standard and droplet precautions are insufficient for TB transmission
prevention. The client should be placed in a private room with negative airflow.
2. A client with tuberculosis is prescribed a four-drug regimen.
The nurse understands that which medication is hepatotoxic?
A. Isoniazid
B. Rifampin
C. Pyrazinamide
D. All of the above
,Answer: D
Rationale: Isoniazid, rifampin, and pyrazinamide are all hepatotoxic medications used in
the treatment of tuberculosis . The nurse should monitor liver function tests and educate
the client to avoid alcohol and report signs of liver toxicity such as jaundice, dark urine,
or nausea.
3. A nurse is providing discharge teaching to a client recently
diagnosed with TB. Which statement by the client indicates
correct understanding of the teaching? (Select all that apply)
A. "I will follow up with my healthcare provider regularly"
B. "My family does not require testing"
C. "I need to strictly adhere to my medication schedule"
D. "I will avoid alcoholic beverages while on this treatment plan"
Answer: A, C, D
Rationale: Clients with TB must adhere to the full medication schedule, avoid alcohol
due to hepatotoxicity risk, and follow up regularly with healthcare providers . Family
members and close contacts should be tested for TB exposure, so option B is incorrect.
4. Which diagnostic test is needed to confirm a tuberculosis
diagnosis?
A. Complete blood count
B. Chest x-ray
C. Mantoux skin test
D. Sputum culture
Answer: D
Rationale: A sputum culture is the definitive test for confirming a tuberculosis
diagnosis . A chest x-ray and Mantoux skin test are screening tools but are not
confirmatory for active TB. A positive Mantoux test indicates exposure, not active
disease.
,5. The nurse is caring for a client with end-stage emphysema.
Which laboratory finding would the nurse expect?
A. pH 7.35
B. CO2 30 mm Hg
C. CO2 50 mm Hg
D. Decreased CO2
Answer: C
Rationale: Clients with end-stage emphysema often have chronic CO2 retention due to
air trapping and ineffective gas exchange. A CO2 level of 50 mm Hg indicates
hypercapnia, which is expected in advanced COPD . This reflects the respiratory acidosis
that accompanies advanced lung disease.
6. A nurse is caring for a client who has emphysema. Which
findings should the nurse expect to assess in this client? (Select all
that apply)
A. Tripod position
B. Wheezing
C. Tachypnea
D. Barrel chest
E. Distended jugular vein
Answer: A, B, C, D, E
Rationale: Clients with emphysema may present with tripod positioning (leaning
forward to breathe), wheezing, tachypnea, barrel chest from air trapping, and distended
jugular veins due to increased intrathoracic pressure . These are all expected findings in
advanced COPD.
7. The nurse is admitting a client with new onset of dyspnea and
productive cough with suspected pneumonia. The client has an
oxygen saturation of 96% on 2L O2 via nasal cannula, crackles in
, bilateral lung bases, temperature 98.9°F, heart rate 103, and
respiratory rate 18. Which order should the nurse perform first?
A. Administer broad-spectrum antibiotics
B. Collect sputum sample for culture
C. Administer antipyretic for temperature
D. Collect blood sample for complete blood count
Answer: B
Rationale: The priority is to collect a sputum sample for culture before initiating
antibiotics . This ensures accurate identification of the causative organism. The client is
stable with 96% oxygen saturation, so antibiotics can be administered after the sputum
culture is obtained.
8. A nursing student is teaching a client about their new diagnosis
of pulmonary fibrosis. Which statement would the student
include in the teaching?
A. "A sputum culture may show the presence of mycobacterium"
B. "Most clients have progressive disease with a life expectancy of less than 5 years"
C. "This is an incurable, autosomal recessive genetic disease that affects many organs"
D. "Inflammation of the mucous membranes in the airways can trigger an attack"
Answer: B
Rationale: Pulmonary fibrosis is a progressive disease with a poor prognosis; many
clients have a life expectancy of less than 5 years after diagnosis . It is not caused by
mycobacterium (tuberculosis), is not typically autosomal recessive (cystic fibrosis), and
does not involve airway inflammation like asthma .
9. A client with suspected TB is admitted to the hospital. Along
with a private room, which of the following is appropriate related
to isolation procedures?
A. Positive pressure room
B. Standard surgical mask for staff
