Oxygenation NCLEX Questions Questions
Question 1 of 5
The client has been admitted with complaints of shortness of breath of 2 weeks duration and has received the nursing diagnosis Impaired Gas Exchange. Which admission laboratory result would support the choice of this diagnosis?
Correct Answer: A
Rationale: Impaired Gas Exchange leads to chronic hypoxia prompting the body to increase erythrocyte production to enhance oxygen-carrying capacity resulting in increased hematocrit (A). Decreased BUN (B) relates to renal function not gas exchange. Increased blood sugar (C) is unrelated to oxygenation. Increased sedimentation rate (D) indicates inflammation but is nonspecific making A the supportive finding for this diagnosis.
Question 2 of 5
The nurse who is assessing a clients chest tube insertion site notices a fine crackling sound and feeling upon palpating the area. What action should the nurse take?
Correct Answer: B
Rationale: Crackling (subcutaneous emphysema) indicates air in subcutaneous tissues possibly from a poor chest tube seal. Collaborating with the physician (B) is necessary to evaluate and address the issue as it may require intervention. Discontinuing suction (A) or removing the tube (C) is unsafe without physician guidance. Reinforcing the dressing (D) does not address the underlying cause making B the appropriate action.
Question 3 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 4 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 5 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
