ATI Nurs 201 Med Surg 2 Exam Questions
Extract:
Question 1 of 5
A nurse is monitoring a client with COPD that suddenly becomes restless and anxious. Which of the following steps should the nurse take next?
Correct Answer: D
Rationale: Pursed-lip breathing helps increase oxygenation and decrease the work of breathing in COPD patients, addressing restlessness and anxiety caused by hypoxia or hypercapnia.
Question 2 of 5
A nurse in the med-surgical ICU is evaluating a patient with a diagnosis of chronic copd. The patient is receiving oxygen at a flow rate of 10 L/min via facemask. Which finding would concern the nurse to act immediately?
Correct Answer: A
Rationale: A respiratory rate of 8 bpm indicates respiratory depression, potentially due to high-flow oxygen suppressing the respiratory drive in COPD patients, requiring immediate intervention.
Question 3 of 5
The patient asks the nurse what the P Wave indicates on an EKG strip. The nurse informs the patient that the P Wave represents:
Correct Answer: D
Rationale: The P wave represents the passage of the electrical impulse through the atria, leading to atrial depolarization and contraction, initiating the cardiac cycle.
Question 4 of 5
What condition do these results indicate? A nurse is reviewing arterial blood gas lab values on her newly admitted elderly client. The ABG results are as follows: pH 7.21, PaCO2 50, HCO3 26.
Correct Answer: A
Rationale: The pH of 7.21 indicates acidosis, and the elevated PaCO2 of 50 mmHg suggests carbon dioxide retention, characteristic of respiratory acidosis due to inadequate CO2 expulsion.
Question 5 of 5
A nurse in the respiratory unit is caring for client who has a past medical history of heart failure and is currently admitted for asthma exacerbation. When reviewing the provider's orders further clarification is needed for which of the following medications?
Correct Answer: B
Rationale: Metoprolol, a beta-blocker, can exacerbate bronchospasm in asthma patients by blocking beta-2 receptors in the lungs, requiring clarification due to the client's asthma.
