Oxygenation NCLEX Questions Questions
Question 1 of 5
A nurse educator is presenting a module on basic first aid for newly licensed home health nurses. The client who has heat stroke will have which of the following?
Correct Answer: A
Rationale: Heat stroke is a medical emergency with elevated body temperature and organ dysfunction. Hypotension (A) occurs due to dehydration and vasodilation. Bradycardia (B) is incorrect as tachycardia is typical. Clammy skin (C) is more associated with heat exhaustion; heat stroke presents with hot dry skin. Bradypnea (D) is incorrect as tachypnea is common. Thus A is correct for heat stroke symptoms.
Question 2 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 3 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 4 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 5 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.
