Oxygenation NCLEX Questions Questions
Question 1 of 5
The nurse encourages the client to expectorate sputum rather than swallowing it. What is the rationale for this direction?
Correct Answer: C
Rationale: Expectorating sputum allows the nurse to assess its quality (color consistency) and quantity (C) aiding in diagnosis and treatment evaluation. Sputum bacteria (A) are not inherently harmful if swallowed as stomach acid neutralizes them. Swallowing sputum (B) is not dangerous unless aspiration occurs which is unlikely if swallowing is intact (D). Thus C is the primary rationale for expectoration.
Question 2 of 5
The nurse is planning the care of a client who has need for frequent suctioning. What should the nurse delegate to the UAP?
Correct Answer: B
Rationale: Oral suctioning (B) is nonsterile and can be delegated to UAP as it involves clearing the mouth not the airway. Tracheal suctioning (C) is sterile and requires nursing judgment making it non-delegable. Delegating both (A) or neither (D) is incorrect as UAP can safely perform oral suctioning under supervision making B the appropriate delegation.
Question 3 of 5
A client is demonstrating signs of hypoxia. What laboratory value will help the nurse determine the clients degree of effective gas exchange?
Correct Answer: D
Rationale: Arterial blood gas (ABG D) measures $\mathrm{PaO} 2$ and $\mathrm{PaCO} 2$ directly assessing gas exchange efficiency and hypoxia severity. Blood glucose (A) potassium (B) and sodium (C) do not reflect oxygenation status making D the critical lab value for evaluating respiratory function and hypoxia.
Question 4 of 5
The nurse is conducting a health history for a client with a respiratory disorder. What should the nurse include in this assessment?
Correct Answer: A
Rationale: A comprehensive respiratory history includes lifestyle (A) for risk factors (e.g. smoking) presence of cough (B) for type and duration sputum production (C) for characteristics and pain (D) for location and impact on breathing. Diet (E not listed) is less relevant making A
Question 5 of 5
The nurse has completed nasopharyngeal suctioning of a client. What should the nurse NOT document about this procedure?
Correct Answer: B
Rationale: Lung sounds before and after Oxygen saturation after) Documentation includes sputum characteristics (A) for infection monitoring lung sounds before (C) and after (D) to assess effectiveness and oxygen saturation after (E) for hypoxia evaluation. Sterile solution amount (B) is not typically documented making A C D essential for comprehensive records.
