The portion of the lung ventilated by one bronchioles is called......
- A. terminal bronchioles
- B. bronchioles tree
- C. Pulmonary lobule
- D. primary bronchioles
Correct Answer: C
Rationale: The correct answer is C: Pulmonary lobule. A pulmonary lobule is the portion of the lung ventilated by one bronchiole. This is because each bronchiole branches into smaller airways ending in clusters of alveoli called pulmonary lobules. The other choices are incorrect because: A) Terminal bronchioles are the smallest airways in the respiratory tract, not the portion of the lung ventilated by one bronchiole. B) Bronchiole tree is not a specific anatomical term. D) Primary bronchioles are the branches of the main bronchi and are not associated with the specific portion of the lung ventilated by one bronchiole.

A female client must take streptomycin for tuberculosis. Before therapy begins, the nurse should instruct the client to notify the physician if a health concern occurs?
- A. Impaired color discrimination
- B. Increased urinary frequency
- C. Decreased hearing acuity
- D. Increased appetite
Correct Answer: C
Rationale: The correct answer is C: Decreased hearing acuity. Streptomycin is known to cause ototoxicity, which can lead to decreased hearing acuity. Therefore, the nurse should instruct the client to notify the physician if any changes in hearing occur to prevent permanent hearing loss. Impaired color discrimination (A) and increased appetite (D) are not commonly associated with streptomycin use. Increased urinary frequency (B) is not a typical side effect of streptomycin and would not require immediate physician notification.
The nurse has assessed a patient's family history for three generations. The presence of
which respiratory disease would justify this type of assessment?
- A. Asthma
- B. Obstructive sleep apnea
- C. Community-acquired pneumonia
- D. Pulmonary edema
Correct Answer: A
Rationale: Step-by-step rationale:
1. Asthma is a hereditary respiratory disease, making it important to assess family history.
2. Genetic predisposition plays a role in the development of asthma.
3. Understanding family history helps in identifying potential risk factors.
4. Obstructive sleep apnea, community-acquired pneumonia, and pulmonary edema are not typically hereditary respiratory diseases.
5. Therefore, assessing family history for three generations is justified for asthma.
A nurse is caring for a client with acute respiratory distress syndrome. Which of the following would the nurse expect to note in the client?
- A. Decreased respiratory rate.
- B. Pallor.
- C. Low arterial PaO2.
- D. An elevated arterial PaO2.
Correct Answer: C
Rationale: The correct answer is C: Low arterial PaO2. In acute respiratory distress syndrome (ARDS), there is impaired gas exchange leading to hypoxemia. Low arterial PaO2 indicates poor oxygenation in the blood, a hallmark of ARDS. Decreased respiratory rate (A) is unlikely as the body compensates by increasing respiratory effort. Pallor (B) is a general sign of reduced blood flow and not specific to ARDS. An elevated arterial PaO2 (D) would not be expected in ARDS, as it signifies adequate oxygenation.
A nurse cares for a client who has hypertension that has not responded well to several medications. The client states compliance is not an issue. What action would the nurse take next?
- A. Assess the client for obstructive sleep apnea.
- B. Arrange a home sleep apnea test.
- C. Encourage the client to begin exercising.
- D. Schedule a polysomnography
Correct Answer: A
Rationale: The correct answer is A: Assess the client for obstructive sleep apnea. Hypertension that is not responding to medications may be due to underlying sleep apnea, a common comorbidity. By assessing for obstructive sleep apnea, the nurse can identify a potential contributing factor to the client's uncontrolled hypertension. This step is crucial in managing the client's condition effectively.
Summary of other choices:
B: Arranging a home sleep apnea test may be premature without first assessing the client for obstructive sleep apnea.
C: Encouraging the client to begin exercising is important for overall health but may not directly address the uncontrolled hypertension.
D: Scheduling a polysomnography may be necessary if obstructive sleep apnea is suspected after the initial assessment.
What is an advantage of a tracheostomy over an endotracheal (ET) tube for long-term management of an upper airway obstruction?
- A. A tracheostomy is safer to perform in an emergency.
- B. An ET tube has a higher risk of tracheal pressure necrosis.
- C. A tracheostomy tube allows for more comfort and mobility.
- D. An ET tube is more likely to lead to lower respiratory tract infection.
Correct Answer: C
Rationale: A tracheostomy tube allows for more comfort and mobility compared to an endotracheal tube, making it preferable for long-term management of an upper airway obstruction. The ability to speak, eat, and move more freely with a tracheostomy tube can significantly improve the quality of life for the patient.
