Oxygenation Nursing Practice Questions Questions
Question 1 of 5
A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3"“ 18 mEq/L. The nurse would expect which finding?
Correct Answer: B
Rationale: The correct answer is B: Kussmaul respirations. The ABG results indicate metabolic acidosis (low pH, low HCO3-), causing respiratory compensation to lower PaCO2. Kussmaul respirations are deep, rapid breaths to blow off CO2 and normalize pH. Intercostal retractions (A) are seen in respiratory distress, not metabolic acidosis. Low SpO2 (C) is not directly related to the ABG results. Decreased venous O2 pressure (D) is not a typical finding in this scenario.
Question 2 of 5
A nurse is caring for a patient who is receiving mechanical ventilation. What is the priority action?
Correct Answer: D
Rationale: The correct answer is D: Monitor the ventilator settings. This is the priority action because monitoring the ventilator settings ensures that the patient is receiving the appropriate oxygenation and ventilation support. By continuously monitoring the settings, the nurse can detect any changes or malfunctions promptly, preventing potential complications. Explanation of other choices: A: Checking the ventilator settings is important, but monitoring them continuously is more crucial. B: Performing a chest x-ray may provide additional information but is not the priority when assessing a patient on mechanical ventilation. C: Increasing fluid intake is not directly related to the immediate care of a patient on mechanical ventilation and is not the priority action.
Question 3 of 5
A nurse is caring for a patient who is receiving chemotherapy. The patient is experiencing alopecia. What is the priority nursing intervention?
Correct Answer: C
Rationale: The correct answer is C: Encourage early ambulation. Chemotherapy patients often experience alopecia as a side effect. Early ambulation helps improve circulation, prevent complications like blood clots, and enhance overall well-being. It is a priority nursing intervention as it promotes physical activity and aids in the patient's recovery. Providing a wig prostheses (choice A) and emotional support (choice B) are important but not the priority when compared to promoting physical activity. Administering a calcium channel blocker (choice D) is irrelevant to addressing alopecia in chemotherapy patients.
Question 4 of 5
A nurse is caring for a patient with a history of diabetes who is experiencing an acute episode of hyperglycemia. What is the priority action?
Correct Answer: A
Rationale: The correct answer is A: Administer insulin. In hyperglycemia, administering insulin is the priority as it helps lower blood glucose levels effectively. Insulin is essential in managing high blood sugar levels in diabetic patients. Administering subcutaneous insulin (choice B) may not act fast enough in acute situations. Administering intravenous fluids (choice C) can help with hydration but does not address the primary issue of high blood sugar. Administering fluids alone (choice D) does not directly address hyperglycemia. Therefore, administering insulin is the most crucial action to manage hyperglycemia effectively.
Question 5 of 5
A nurse is caring for a patient with a history of stroke who is complaining of sudden loss of vision in one eye. What should the nurse do first?
Correct Answer: C
Rationale: The correct answer is C: Reassure the patient. In this situation, sudden loss of vision in one eye could be a sign of a transient ischemic attack (TIA) or a retinal artery occlusion, which can be frightening for the patient. The nurse's first priority should be to provide emotional support and reassurance to the patient to alleviate anxiety and stress. Once the patient is calmer, the nurse can then proceed to assess for changes in neurological status, notify the healthcare provider, and monitor vital signs. Reassurance is crucial in ensuring the patient's well-being and promoting effective communication.
