Which of the following is NOT found in lung tissue?
- A. blood capillaries
- B. alveolar sacs
- C. interstitial fluid
- D. muscle
Correct Answer: D
Rationale: The correct answer is D: muscle. Lung tissue does not contain muscle tissue; instead, it is primarily composed of alveolar sacs for gas exchange, blood capillaries for oxygen exchange, and interstitial fluid for support. Muscles are not part of the structure of the lungs as they are not involved in the respiratory process. In summary, muscles are not found in lung tissue, making option D the correct choice.

Severing the sensory fibers from the lungs would result in all of the following except
- A. less inhibition of the inspiratory center during forced breathing
- B. a drop in tidal volume
- C. potential damage to the lungs due to overinflation
- D. a disappearance of the Hering-Breuer reflexes
Correct Answer: B
Rationale: The correct answer is B: a drop in tidal volume. Severing sensory fibers from the lungs would lead to decreased feedback to the brain, resulting in less inhibition of the inspiratory center and potentially overinflation of the lungs (choice C). The Hering-Breuer reflexes, responsible for preventing lung over-inflation, would disappear (choice D). However, tidal volume is primarily controlled by the respiratory muscles and respiratory center in the brain, not solely by sensory input from the lungs. Hence, severing sensory fibers would not directly lead to a drop in tidal volume.
Spirometry is used
- A. To detect the amount of Hemoglobin
- B. To detect the air flow through the respiratory system
- C. To check the respiratory quotient
- D. None of these
Correct Answer: B
Rationale: The correct answer is B: To detect the air flow through the respiratory system. Spirometry measures lung function by assessing the volume of air inhaled and exhaled. It helps in diagnosing respiratory conditions like asthma or COPD. Choice A is incorrect because spirometry does not measure hemoglobin levels. Choice C is incorrect as spirometry does not determine the respiratory quotient, which relates to metabolic processes. Choice D is incorrect as spirometry is used for assessing respiratory function.
When obtaining a health history from a 76-year-old patient with suspected CAP, what does the nurse expect the patient or caregiver to report?
- A. Confusion
- B. An abrupt onset of fever and chills
- C. A recent loss of consciousness
- D. A gradual onset of headache and sore throat
Correct Answer: B
Rationale: In patients with Community-Acquired Pneumonia (CAP), an abrupt onset of fever and chills is a common symptom to expect. This is due to the rapid inflammatory response in the lungs. Confusion, loss of consciousness, and gradual headache and sore throat are less likely to be reported initially.
A client is admitted with suspected pneumonia from the emergency department. The client went to the primary health care provider a few days ago" and shows the nurse the results of what the client calls an allergy test" as shown below: The reddened area is firm. What action by the nurse is best?
- A. Call the primary health care provider's office to request records.
- B. Immediately place the client on Airborne Precautions.
- C. Prepare to begin administration of intravenous antibiotics.
Correct Answer: C
Rationale: The correct answer is C: Prepare to begin administration of intravenous antibiotics. This is the best action because the client is suspected of having pneumonia, which is commonly treated with antibiotics. The nurse should prepare to start IV antibiotics to address the infection promptly.
Choice A is incorrect because requesting records from the primary health care provider's office may delay treatment. Choice B is incorrect because airborne precautions are not necessary for suspected pneumonia. Choice D is incomplete and does not provide a clear action plan for addressing the client's condition.
Which of the following should the nurse include in the teaching plan of a client with acute bronchitis?
- A. Not coughing frequently
- B. Consuming adequate calories
- C. Washing the hands frequently
- D. Encouraging a semi-Fowler’s position
Correct Answer: C
Rationale: The correct answer is C. Frequent handwashing prevents the spread of infection, which is crucial in managing acute bronchitis. A (not coughing frequently) is impractical and counterproductive. B (consuming adequate calories) supports general health but is not specific. D (semi-Fowler’s position) may aid breathing but is not a primary teaching point.
