Nursing Questions on Oxygenation Questions
Question 1 of 5
A patient with COPD is hospitalized for increasing shortness of breath. Which assessment finding requires immediate intervention?
Correct Answer: B
Rationale: The correct answer is B because an oxygen saturation of 85% on room air indicates severe hypoxemia and requires immediate intervention to prevent organ damage. Oxygen therapy is needed to improve oxygenation. Choice A (Barrel-shaped chest) is a common finding in patients with COPD but does not require immediate intervention. Choice C (Increased anterior-posterior chest diameter) is also a common finding in patients with COPD and does not require immediate intervention. Choice D (Productive cough with yellow sputum) is concerning for a respiratory infection but does not indicate an immediate need for intervention to address the hypoxemia.
Question 2 of 5
A patient diagnosed with active tuberculosis (TB) is homeless and has a history of alcohol abuse. Which intervention by the nurse will be most effective in ensuring adherence with the treatment regimen?
Correct Answer: C
Rationale: The correct answer is C: Arrange for the patient's friend to administer the medication on schedule. This intervention addresses the patient's social support system, ensuring someone close to them can help with medication adherence. Homelessness and alcohol abuse can make it challenging for the patient to adhere to the treatment regimen independently. Providing support from a trusted friend can increase accountability and motivation. A: Repeating warnings may not address the underlying issues of homelessness and alcohol abuse. B: Giving written instructions may not be effective if the patient struggles with literacy or forgetfulness. D: While providing meals and drug administration at a community center may be helpful, it doesn't address the patient's need for personalized support.
Question 3 of 5
A nurse is caring for a patient who is scheduled for a colonoscopy. What should the nurse do first?
Correct Answer: A
Rationale: The correct answer is A: Administer a laxative. Administering a laxative is the first step before a colonoscopy to ensure the colon is clear for better visualization. High fiber intake (B) may be recommended after the procedure. Stool softeners (C) are used for constipation but not typically prior to a colonoscopy. Encouraging ambulation (D) is beneficial post-procedure but not the first step.
Question 4 of 5
A nurse is caring for a patient who is recovering from surgery. The patient is experiencing hypothermia. What is the priority nursing action?
Correct Answer: A
Rationale: The correct answer is A: Administer warming measures. The priority nursing action for a patient experiencing hypothermia is to prevent further heat loss and actively rewarm the patient to restore normal body temperature. This is crucial to prevent complications such as cardiac arrhythmias and impaired immune function. Administering warming measures, such as using warming blankets, heating pads, warm IV fluids, and adjusting room temperature, helps to increase the patient's core body temperature. Administering oxygen therapy (B) may be necessary for other conditions but is not the priority in this scenario. Repositioning the patient (C) may help with comfort and circulation but does not address the underlying issue of hypothermia. Administering antipyretics (D) is used to reduce fever, not hypothermia, and would not be effective in this case.
Question 5 of 5
The nurse develops a teaching plan to help increase activity tolerance at home for an older adult with severe chronic obstructive pulmonary disease (COPD). Which instructions would be appropriate for the nurse to include in the plan of care?
Correct Answer: D
Rationale: Correct Answer: D Rationale: 1. Walking 15 to 20 minutes a day at least 3 times/week is appropriate for an older adult with severe COPD to gradually improve activity tolerance without overexertion. 2. Regular, moderate exercise can help improve cardiovascular function and lung capacity in COPD patients. 3. Consistent schedule of 3 times/week allows for adequate rest periods in between exercise sessions. Summary: A: Incorrect. Walking 15 to 20 minutes a day is more beneficial than just 3 times/week. B: Incorrect. Limiting exercise to ADLs may not provide enough physical activity to improve activity tolerance. C: Incorrect. Exceeding a pulse rate of 130 beats/minute may be too strenuous for an older adult with severe COPD.
