Questions on Respiratory System Questions
Question 1 of 5
The nurse is performing an occupational history as part of the respiratory assessment. Which occupation(s) place the patient isn't at increased risk for an occupational lung disorder?
Correct Answer: D
Rationale: The correct answer is D: A bartender. Bartenders are not typically exposed to occupational lung hazards like smoke, dust, or chemicals. Firefighters (A), cotton gin workers (B), and construction contractors (C) are all at increased risk due to exposure to smoke, cotton dust, and construction materials, respectively. As a result, the bartender is the least likely to develop an occupational lung disorder compared to the other professions listed.
Question 2 of 5
The nurse supervises unlicensed assistive personnel (UAP) providing care for a client who has right lower lobe pneumonia. Which action by the UAP requires the nurse to intervene?
Correct Answer: D
Rationale: Correct Answer: D Rationale: 1. In right lower lobe pneumonia, positioning the client with the affected side down helps improve ventilation and drainage. 2. Lowering the head of the bed to 15 degrees promotes pooling of secretions, worsening respiratory status. 3. A, B, and C are appropriate actions that promote client comfort and safety in pneumonia management. 4. Intervening in option D is crucial to prevent complications and promote effective respiratory care.
Question 3 of 5
How much does the inspired O2 concentration have to be raised to abolish the hypoxaemia?
Correct Answer: B
Rationale: The correct answer is B (7%). To abolish hypoxemia, inspired O2 concentration needs to be increased sufficiently to raise arterial oxygen levels. A 7% increase is generally effective in achieving this without causing oxygen toxicity. Choices A, C, and D are incorrect because a 5% increase may not be enough to abolish hypoxemia, a 10% increase can lead to oxygen toxicity, and a 15% increase is excessive and unnecessary for treating hypoxemia. Therefore, option B is the most appropriate and balanced choice for addressing hypoxemia effectively.
Question 4 of 5
The organ of the respiratory system that traps bacteria with a ring of tonsils is the:
Correct Answer: B
Rationale: The correct answer is B: pharynx. The pharynx is the organ that traps bacteria with its tonsils. The tonsils are located in the pharynx and act as the body's first line of defense against pathogens entering the respiratory system. The nose (choice A) is responsible for warming, humidifying, and filtering air, but it does not trap bacteria with tonsils. The larynx (choice C) is involved in sound production and preventing food from entering the airway, not trapping bacteria. The trachea (choice D) is the windpipe that carries air to and from the lungs, but it does not have tonsils to trap bacteria.
Question 5 of 5
Nurse Reese is caring for a client hospitalized with acute exacerbation of chronic obstructive pulmonary disease. Which of the following would the nurse expect to note on assessment of this client?
Correct Answer: B
Rationale: The correct answer is B: A hyperinflated chest noted on the chest x-ray. In COPD, air trapping leads to hyperinflation of the lungs, causing the chest to appear hyperinflated on x-ray. This is due to the increased residual volume and decreased expiratory flow rates in COPD. Incorrect choices: A: Hypocapnia is unlikely in COPD as patients typically retain carbon dioxide due to impaired gas exchange. C: Increased oxygen saturation with exercise is unlikely in COPD as these patients often have decreased oxygen saturation due to impaired gas exchange. D: A widened diaphragm would not be a typical finding on chest x-ray in COPD; hyperinflated lungs are more characteristic.
