Multiple Choice Questions and Answers on Respiratory System Questions
Question 1 of 5
Exchange across a membrane requires
Correct Answer: D
Rationale: Exchange across a membrane involves the movement of molecules or ions. Moisture (A) helps facilitate this movement by dissolving solutes. Transport proteins (B) are essential for facilitating the movement of specific molecules across the membrane. Pressure gradients (C) can drive the movement of substances across the membrane. Therefore, the correct answer is D, as all these factors play a crucial role in facilitating exchange across a membrane. Moisture alone is not sufficient for exchange, transport proteins are necessary for specific molecule transport, and pressure gradients can aid in driving the movement of substances.
Question 2 of 5
When the oxygen supply to the tissues is inadequate, the condition is
Correct Answer: A
Rationale: The correct answer is A: Hypoxia. Hypoxia refers to inadequate oxygen supply to the tissues, leading to tissue damage. Asphyxia is a condition of suffocation due to lack of oxygen supply. Pleurisy is inflammation of the lining of the lungs, not directly related to oxygen supply. Anoxia is a severe form of hypoxia where there is complete deprivation of oxygen to the tissues. In this context, hypoxia best describes the condition of inadequate oxygen supply to the tissues.
Question 3 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 4 of 5
A nurse cares for a client who had a bronchoscopy 2 hours ago. The client asks for a drink of water. What action would the nurse take next?
Correct Answer: C
Rationale: The correct answer is C: Assess the client's gag reflex before giving any food or water. After a bronchoscopy, the client's gag reflex may be compromised, increasing the risk of aspiration. Assessing the gag reflex is crucial to ensure the client can safely swallow without the risk of choking or aspirating. This step is essential before providing any food or water to prevent potential complications. Incorrect Choices: A: Calling the primary health care provider for food and water is unnecessary as the nurse can make this decision based on assessment. B: Providing ice chips instead of water does not address the need for assessing the gag reflex before giving any form of intake. D: Letting the client have a small sip without assessing the gag reflex first can pose a risk of aspiration if the reflex is impaired.
Question 5 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.
