Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
A nurse is caring for a patient prescribed continuous cardiac monitoring for heart dysrhythmias. Which rhythm will cause the nurse concern?
Correct Answer: C
Rationale: Ventricular tachycardia is a potentially fatal dysrhythmia requiring immediate intervention due to ineffective cardiac output. Sinus rhythm is normal, atrial fibrillation is manageable, and premature atrial contractions are typically benign.
Question 2 of 5
A patient with a chest tube reports sudden dyspnea. What is the priority action?
Correct Answer: A
Rationale: Sudden dyspnea with a chest tube suggests blockage or disconnection. Checking patency ensures proper lung re-expansion and oxygenation, taking priority over pain meds, oxygen increase, or repositioning.
Question 3 of 5
A nurse is preparing a patient for a thoracentesis. What is the priority nursing action?
Correct Answer: B
Rationale: Positioning the patient upright facilitates fluid drainage during thoracentesis and ensures safety, taking priority over monitoring BP, sedation, or checking saturation initially.
Question 4 of 5
A patient with a history of heart disease reports dyspnea on exertion. What is the likely cause?
Correct Answer: B
Rationale: Left heart failure causes pulmonary congestion, leading to dyspnea on exertion, common in heart disease. Pulmonary embolism, pneumothorax, or bronchitis are less directly tied to exertion.
Question 5 of 5
A patient with chest pain and hypoxia is suspected of having which condition?
Correct Answer: A
Rationale: Myocardial infarction can cause chest pain and hypoxia due to reduced cardiac output and oxygenation, more acutely than pneumonia, asthma, or pleurisy.
