Critical Care Respiratory Questions Questions
Question 1 of 4
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 2 of 4
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 3 of 4
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 4 of 4
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
