Critical Care Respiratory Questions Questions
Question 1 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 2 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 3 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
Question 4 of 5
The nurse is performing nasotracheal suctioning of a client. What should the nurse do when suctioning this client?
Correct Answer: A
Rationale: Nasotracheal suctioning should apply suction for 5-10 seconds (A) to minimize hypoxia and trauma with intermittent suctioning. Suctioning for 10 minutes (B) is excessive and dangerous. Applying suction during insertion (C) risks mucosal damage. 20-30 seconds (D) is too long increasing hypoxia risk making A the correct technique.
Question 5 of 5
The nurse is planning care for a client with an oral endotracheal tube. Which interventions should be included in this clients plan of care?
Correct Answer: A
Rationale: E (Insert oropharyngeal airway Nasal care Oral hygiene Move tube every 8 hours) Care includes an oropharyngeal airway (A) to prevent biting nasal care (B) and oral hygiene (C) every 2-4 hours for cleanliness and moving the tube (E) every 8 hours to prevent mucosal irritation. Non-humidified airflow (D) is incorrect as humidification is necessary
