Critical Care Respiratory Questions Questions
Question 1 of 5
The nurse is caring for a client with a tracheostomy. For what protective mechanism will the nurse monitor in the client?
Correct Answer: B
Rationale: A tracheostomy bypasses the nasal passages which normally filter humidify and warm inspired air (B). This protective mechanism is lost increasing the risk of respiratory infections and dryness requiring monitoring. The ability to cough (A) is not directly affected by the tracheostomy. The sneeze reflex (C) is irrelevant as it involves nasal passages. Decreased oxygen-carrying capacity (D) is not a protective mechanism and is unrelated to tracheostomy effects making B correct.
Question 2 of 5
A client has a newly created tracheostomy for mechanical ventilation after a surgical procedure. What action should the nurse plan for this client?
Correct Answer: D
Rationale: The tracheostomy obturator is used to reinsert the tube if dislodged so taping it to the head of the bed (D) ensures immediate availability. Deflating the cuff (A) is not routine and risks aspiration. Elastic bandages (B) are unsafe for securing ties as they lack stability. Removing the inner cannula (C) is part of cleaning but not the priority here making D the correct action for safety.
Question 3 of 5
The nurse has just initiated oxygen by nasal cannula for a client with the medical diagnosis of chronic obstructive pulmonary disease. What is the nurses next action?
Correct Answer: B
Rationale: Padding the tubing at the ears (B) prevents pressure irritation enhancing comfort and compliance. Filling the humidifier (A) is important but not the immediate next step. Setting to 5 liters (C) risks CO2 retention in COPD and requires physician guidance. Ties (D) are not standard for nasal cannulas making B the correct next action for client comfort.
Question 4 of 5
A client who was a victim of a house fire is coughing. The nurse realizes that the purpose of the cough is to
Correct Answer: C
Rationale: Coughing removes irritants from the trachea and bronchi (C) where mucus traps particles and cilia sweep them upward. It does not primarily improve oxygenation (A) or involve nasal passages (B). Closing the glottis (D) is unrelated to cough function making C the correct purpose especially relevant after smoke inhalation.
Question 5 of 5
The nurse is assessing an older client. What effects of aging should the nurse keep in mind during this assessment?
Correct Answer: A
Rationale: E (Decreased cough reflex Dry mucous membranes Increased risk of aspiration) Aging reduces cough reflex (A) increasing aspiration risk (E) and dries mucous membranes (D) impairing airway clearance. Stiffening of blood vessels (B) affects cardiovascular health not respiratory. Altered protein synthesis (C) is nonspecific and unrelated making A
