Chronic Obstructive Pulmonary Disease (COPD) includes
- A. Emphysema
- B. Bronchitis
- C. Asthma
- D. All these
Correct Answer: D
Rationale: The correct answer is D because Chronic Obstructive Pulmonary Disease (COPD) is an umbrella term that encompasses both emphysema and bronchitis. Emphysema is characterized by damage to the air sacs in the lungs, while bronchitis involves inflammation of the bronchial tubes. Asthma, on the other hand, is a separate condition characterized by reversible airway obstruction. Therefore, choices A, B, and C are incorrect, as only emphysema and bronchitis fall under the category of COPD.

A nurse is assessing a client who is recovering from a lung biopsy. The client's breath sounds are absent. While another nurse calls the Rapid Response Team
- A. what action by the nurse takes is most important?
- B. Take a full set of vital signs.
- C. Obtain pulse oximetry reading.
- D. Ask the patient about hemoptysis.
Correct Answer: B
Rationale: The correct answer is B, taking a full set of vital signs, as it is crucial in assessing the client's overall condition and detecting any signs of deterioration. Vital signs include blood pressure, heart rate, respiratory rate, and temperature, which provide valuable information about the client's cardiovascular and respiratory status. In this scenario, absent breath sounds indicate potential respiratory compromise, making it essential to monitor vital signs for any signs of respiratory distress or instability.
Choice A is incorrect because calling the Rapid Response Team is important, but assessing the client's vital signs should take priority to provide immediate information on the client's condition. Choice C, obtaining pulse oximetry reading, is also important but may not provide a comprehensive assessment of the client's overall condition compared to a full set of vital signs. Choice D, asking about hemoptysis, is not the most urgent action to take in this situation as assessing vital signs would provide more immediate and critical information for the client's management.
A patient is undergoing testing to see if he has a pleural effusion. Which of the nurse's respiratory assessment findings would be most consistent with this diagnosis?
- A. Increased tactile fremitus, egophony, and a dull sound upon percussion of the chest wall
- B. Decreased tactile fremitus, wheezing, and a hyperresonant sound upon percussion of the chest wall
- C. Lung fields dull to percussion, absent breath sounds, and a pleural friction rub
- D. Normal tactile fremitus, decreased breath sounds, and a resonant sound upon percussion of the chest wall
Correct Answer: C
Rationale: The correct answer is C. Lung fields dull to percussion, absent breath sounds, and a pleural friction rub are consistent with pleural effusion. Dullness on percussion indicates fluid accumulation in the pleural space. Absent breath sounds suggest decreased air movement due to the fluid. A pleural friction rub may be heard due to inflammation of the pleura.
A is incorrect because increased tactile fremitus, egophony, and a dull sound upon percussion are more indicative of pneumonia.
B is incorrect because decreased tactile fremitus, wheezing, and a hyperresonant sound upon percussion are more indicative of COPD or emphysema.
D is incorrect because normal tactile fremitus, decreased breath sounds, and a resonant sound upon percussion are more indicative of asthma or atelectasis.
The concentration of carbon dioxide in the earth's atmosphere is
- A. 0.004 percent.
- B. 0.04 percent.
- C. 0.4 percent
- D. 4.0 percent.
Correct Answer: B
Rationale: The correct answer is B (0.04 percent) because the concentration of carbon dioxide in the Earth's atmosphere is around 400 parts per million (ppm), which is equivalent to 0.04 percent. This concentration is widely accepted by scientific research and measurements. Choice A (0.004 percent) is too low and doesn't accurately reflect the actual concentration. Choice C (0.4 percent) and choice D (4.0 percent) are both too high, which are significantly above the current levels of carbon dioxide in the atmosphere. Therefore, B is the correct choice as it aligns with the established scientific data on carbon dioxide concentration in the atmosphere.
A slightly obese female client with a history of allergy-induced asthma, hypertension, and mitral valve prolapse is admitted to an acute care facility for elective surgery. The nurse obtains a complete history and performs a thorough physical examination, paying special attention to the cardiovascular and respiratory systems. When percussing the client's chest wall, the nurse expects to elicit:
- A. Resonant sounds.
- B. Hyperresonant sounds.
- C. Dull sounds.
- D. Flat sounds.
Correct Answer: A
Rationale: The correct answer is A: Resonant sounds. Percussing the chest of a healthy individual typically elicits resonant sounds due to the presence of air-filled lung tissue. In this case, the client has a history of asthma, which indicates airway inflammation and possible mucus accumulation, making resonant sounds more likely. Hyperresonant sounds (B) are typically heard in conditions like emphysema with increased lung volume. Dull sounds (C) are indicative of fluid or solid tissue present in the lungs, which is not expected in this client. Flat sounds (D) are heard over areas of solid tissue or muscle, not in the chest of a client with respiratory conditions.
Carbon dioxide and water combine to form
- A. hydrochloric acid
- B. oxygen
- C. carbonic acid
- D. carbaminohemoglobin
Correct Answer: C
Rationale: The correct answer is C: carbonic acid. When carbon dioxide and water combine, they form carbonic acid through a chemical reaction known as hydration. This process is essential for the transportation of carbon dioxide in the blood and plays a crucial role in maintaining the body's pH balance. Hydrochloric acid (A) is formed by the reaction of hydrogen chloride gas with water. Oxygen (B) is not a product of the reaction between carbon dioxide and water. Carbaminohemoglobin (D) is a compound formed by the binding of carbon dioxide to hemoglobin in red blood cells, not a direct product of the reaction between carbon dioxide and water.
