Multiple Choice Questions and Answers on Respiratory System Questions
Question 1 of 5
The amount of air that moves in and out of the lungs, with each normal inspiration and expiration is called
Correct Answer: C
Rationale: The correct answer is C: Tidal volume. Tidal volume is the amount of air that moves in and out of the lungs during normal breathing. This volume represents the normal breathing pattern and is essential for gas exchange in the lungs. Residual volume (A) is the air that remains in the lungs after maximal expiration. Vital capacity (B) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. Tidal capacity (D) is not a recognized term in respiratory physiology. Therefore, the correct choice is C as it specifically refers to the air moved during normal breathing.
Question 2 of 5
A nurse teaches a client who had a supraglottic laryngectomy. Which technique would the nurse teach the client to prevent aspiration?
Correct Answer: B
Rationale: The correct answer is B: Swallow twice while bearing down. This technique helps close the trachea during swallowing to prevent aspiration. Swallowing twice initiates a double swallow, which helps clear the throat and reduce the risk of food or liquid entering the airway. Tilt the head back (A), breathing slowly and deeply (C), and keeping the head still and straight (D) do not directly address the risk of aspiration in a client with a supraglottic laryngectomy.
Question 3 of 5
A client has been taking isoniazid for tuberculosis for 3 weeks. What laboratory results need to be reported to the primary health care provider immediately?
Correct Answer: B
Rationale: The correct answer is B: Alanine aminotransferase (ALT): 180 U/L. Elevated ALT levels indicate liver damage, a potential side effect of isoniazid. This is crucial to report immediately to the primary health care provider to assess liver function and adjust medication if needed. A: Albumin levels may fluctuate due to various factors but are not typically urgent in this context. C: RBC count within normal range, not directly related to isoniazid therapy. D: WBC count slightly elevated but not a priority unless there are other concerning symptoms.
Question 4 of 5
What is the least successful treatment for laryngeal cancer?
Correct Answer: D
Rationale: The correct answer is D. Chemotherapy alone is generally less effective for laryngeal cancer compared to surgical treatment, radiation therapy, or combinations thereof. A (surgical treatment) and C (radiation therapy with surgery) are more successful. B (radical neck dissection) is a specific surgical approach but still more effective than chemotherapy alone.
