Oxygenation NCLEX Questions Questions
Question 1 of 5
A client reports shortness of breath and has the following cardiac rhythm. Which medication should the nurse prepare to administer?
Correct Answer: A
Rationale: The ECG represents sinus bradycardia in which the heart rate is less than 60 beats per minute. Atropine is the treatment for symptomatic sinus bradycardia. Atropine is a parasympatholytic or vagolytic agent. (Note: The document does not specify the rhythm, but the rationale indicates sinus bradycardia.)
Question 2 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 3 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 4 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 5 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.
