Question 1
Regular
A nurse is assessing a patient with COPD who is experiencing dyspnea. What action will the nurse take first?
Correct!
Incorrect
The correct answer is: A
Rationale
Place the patient in Fowler position. This position facilitates better lung expansion and improves oxygenation, which is crucial for a patient with COPD experiencing dyspnea, allowing for easier breathing.
B: Encourage diaphragmatic breathing. While helpful in managing dyspnea, this method may not provide immediate relief in acute situations where positioning is more effective for lung function.
C: Ask the patient to cough. Coughing may help clear secretions but does not directly address the immediate need for improved airflow and breathability associated with dyspnea.
D: Initiate oral suctioning of secretions. Suctioning is invasive and typically reserved for patients with significant airway obstruction. It does not prioritize the immediate relief of dyspnea in this scenario.

Question 2
Regular
A nurse is maintaining airway patency in an unconscious patient by providing frequent nasopharyngeal suction. When would the nurse anticipate inserting a nasopharyngeal airway (nasal trumpet)?
Correct!
Incorrect
The correct answer is: D
Rationale
A nasopharyngeal airway (nasal trumpet) would be anticipated when epistaxis is noted with continued suctioning. This intervention helps maintain airway patency, especially when bleeding may obstruct the airway, ensuring safe ventilation.
A: Vomiting during suctioning occurs. While vomiting can compromise airway patency, it does not specifically indicate the need for a nasopharyngeal airway, which is primarily for managing airway obstruction.
B: Secretions appear to contain stomach contents. Stomach contents in secretions suggest aspiration risk but do not necessitate the immediate use of a nasopharyngeal airway for airway management.
C: The suction catheter touches an unsterile surface. This situation raises concerns about infection, yet it does not directly relate to the need for a nasopharyngeal airway in maintaining airway patency.
