Oxygen Cycle Questions and Answers Questions
Question 1 of 5
The nurse is assessing a client with suspected pneumonia. Which diagnostic test is most definitive for confirming the diagnosis?
Correct Answer: C
Rationale: The correct answer is C: Sputum culture and sensitivity. This test is most definitive for confirming pneumonia as it directly identifies the causative organism present in the sputum, guiding appropriate antibiotic therapy. Chest X-ray (A) can show infiltrates but doesn't confirm the pathogen. CBC (B) can show elevated white blood cells, but not specific to pneumonia. ABG analysis (D) assesses gas exchange and oxygenation status, not a direct confirmation of pneumonia.
Question 2 of 5
The nurse palpates the posterior chest while the patient says '99' and notes absent fremitus. Which action should the nurse take next?
Correct Answer: D
Rationale: The correct answer is D because auscultating breath sounds is the next appropriate action after noting absent fremitus. This helps assess for additional signs of respiratory issues. Palpating the anterior chest for barrel chest (choice A) is not necessary at this point. Encouraging the patient to turn, cough, and deep breathe (choice B) is more appropriate for assessing for chest expansion. Reviewing the chest x-ray report for evidence of pneumonia (choice C) is premature without further assessment of breath sounds.
Question 3 of 5
The nurse teaches a patient about peak flow meter use. Which action by the patient indicates that teaching was successful?
Correct Answer: D
Rationale: The correct answer is D because using an albuterol inhaler for peak flows in the yellow zone indicates that the patient understands how to respond to worsening symptoms. Albuterol is a rescue inhaler used to manage asthma exacerbations, which are typically indicated by peak flows in the yellow zone. Inhaling rapidly through the peak flow meter (A) is not the correct technique and can lead to inaccurate readings. Taking montelukast (B) is a daily controller medication and not indicated for immediate symptom relief. Calling the healthcare provider when in the green zone (C) is unnecessary as the green zone signifies good lung function.
Question 4 of 5
What is the priority nursing intervention for a patient with a newly diagnosed pulmonary embolism?
Correct Answer: A
Rationale: The correct answer is A: Administer anticoagulant medication. This is the priority intervention because anticoagulants help prevent the existing clot from getting larger and reduce the risk of new clots forming. Administering anticoagulant medication promptly is essential to prevent complications like worsening of the pulmonary embolism or development of new clots. B: Positioning the patient flat may worsen the condition by reducing blood flow to the lungs. C: Encouraging ambulation may dislodge the clot and lead to a life-threatening situation. D: Chest physiotherapy may not address the underlying cause of the pulmonary embolism and could potentially dislodge the clot. In summary, administering anticoagulant medication is the priority intervention as it directly addresses the pathophysiology of the condition and reduces the risk of complications.
Question 5 of 5
The nurse is teaching a patient with obstructive sleep apnea about using a CPAP machine. Which statement by the patient indicates a need for further teaching?
Correct Answer: B
Rationale: Correct Answer: B - "I should sleep on my back for better airflow." Rationale: 1. Sleeping on the back can worsen obstructive sleep apnea by causing the tongue and soft tissues to block the airway. 2. The optimal sleeping position for CPAP therapy is usually on the side to maintain open airways. 3. Choices A, C, and D are correct as consistent CPAP usage, regular cleaning, and weight loss can improve sleep apnea symptoms.
