Question 2
Which of the following skills can the nurse delegate to nursing assistive
personnel? Select all that apply.
• A. nasotracheal suctioning
• B. oropharyngeal suctioning of a stable patient
• C. suctioning a new artificial airway
• D. permanent tracheostomy tube suctioning
• E. care of an endotracheal tube
Correct Answer: B. oropharyngeal suctioning of a stable patient; D.
permanent tracheostomy tube suctioning
Rationale:
1. Oropharyngeal suctioning of a stable patient can be delegated to NAP.
2. Permanent tracheostomy tube suctioning can be delegated after
training.
3. Nasotracheal suctioning and new artificial airway suctioning require
nursing judgment.
4. Endotracheal tube care requires RN expertise.
5. The source indicates B and D are correct.

A patient was admitted following a motor vehicle accident with multiple
fractured ribs. Respiratory assessment includes signs/symptoms of
secondary pneumothorax. Which are the most common assessment
findings associated with a pneumothorax? Select all that apply.
• A. sharp pleuritic pain that worsens on inspiration
• B. crackles over lung bases of affected lung
• C. tracheal deviation toward the affected lung
• D. worsening dyspnea
• E. absent lung sounds to auscultation on affected side
Correct Answer: A. sharp pleuritic pain that worsens on inspiration; D.
worsening dyspnea; E. absent lung sounds to auscultation on affected side
Rationale:
1. Sharp pleuritic pain is characteristic of pneumothorax (A).
2. Worsening dyspnea indicates respiratory compromise (D).
3. Absent lung sounds occur when air fills the pleural space (E).
4. Tracheal deviation occurs away from, not toward, the affected lung.
5. The source indicates A, D, and E are correct.
