Oxygenation Nursing Practice Questions Questions
Question 1 of 5
The nurse is teaching a patient with asthma about using a metered-dose inhaler (MDI). Which statement indicates the need for further teaching?
Correct Answer: C
Rationale: Rationale: Choice C indicates the need for further teaching because forcefully exhaling after inhaling the medication can reduce the amount of medication reaching the lungs. The correct technique is to hold the breath for 10 seconds to allow the medication to be absorbed effectively. Choices A, B, and D are all correct techniques for using a metered-dose inhaler and do not indicate the need for further teaching.
Question 2 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 3 of 5
A nurse is caring for a patient who is at risk for hypoglycemia. Which intervention should the nurse implement?
Correct Answer: D
Rationale: The correct answer is D: Administer insulin therapy. When a patient is at risk for hypoglycemia, administering insulin can further decrease blood sugar levels, exacerbating the condition. Therefore, the nurse should not administer insulin, glucose, or a snack, as these interventions can worsen hypoglycemia. Administering insulin therapy would be counterproductive and potentially harmful in this situation, making it the correct choice.
Question 4 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 5 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.
