Question 1 of 5
The nurse is providing education to a client with obstructive sleep apnea. Which lifestyle change is most likely to improve symptoms?
Correct Answer: C
Rationale: The correct answer is C: Losing weight if overweight. Obesity is a major risk factor for obstructive sleep apnea as excess fat around the neck can obstruct the airway during sleep. Losing weight can help reduce the severity of symptoms by decreasing the amount of tissue that may be blocking the airway. Sleeping in a supine position (A) can actually worsen symptoms by further collapsing the airway. Avoiding CPAP therapy (B) is not recommended as it is a common treatment for sleep apnea. Reducing daily fluid intake (D) may help with nighttime trips to the bathroom but does not directly address the underlying cause of obstructive sleep apnea.
Question 2 of 5
A nurse is assisting a respiratory therapist with chest physiotherapy for patients with ineffective cough. For which patient might this therapy be recommended?
Correct Answer: C
Rationale: The correct answer is C, a teenager with cystic fibrosis. Chest physiotherapy helps clear mucus from the lungs, which is essential for patients with cystic fibrosis due to thick secretions. Postoperative adults may benefit, but not specifically for ineffective cough. Adults with COPD may require other treatments. Children with pneumonia may not need chest physiotherapy unless secretion clearance is an issue.
Question 3 of 5
The nurse obtains the following assessment data on an older patient who has influenza. Which information will be most important for the nurse to communicate to the health care provider?
Correct Answer: B
Rationale: The correct answer is B: Diffuse crackles in the lungs. This is the most important information to communicate as it indicates possible complications like pneumonia, which requires immediate medical attention. Fever (A), sore throat and cough (C), myalgia and headache (D) are common symptoms of influenza and can be managed symptomatically. However, lung crackles signify a potential serious respiratory issue that needs prompt intervention to prevent further deterioration.
Question 4 of 5
The nurse prepares a patient with acute shortness of breath for arterial blood gas (ABG) collection. Which action is most appropriate?
Correct Answer: C
Rationale: The correct answer is C. Performing the Allen test before puncturing the radial artery ensures adequate collateral circulation in case the radial artery becomes occluded during the ABG collection. This step helps prevent ischemia and other complications. Administering oxygen before obtaining the sample (A) is not recommended as it can alter the ABG results. Positioning the patient supine (B) is not necessary for ABG collection. Keeping the patient NPO for 6 hours (D) is not required for an ABG test.
Question 5 of 5
The nurse is preparing a patient with COPD for spirometry testing. Which instruction should the nurse include?
Correct Answer: A
Rationale: The correct answer is A because bronchodilators can affect spirometry results. Here's the rationale: 1. Bronchodilators can cause bronchodilation, affecting the test results. 2. Avoiding bronchodilators for 6-12 hours helps ensure accurate baseline lung function. 3. Eating/drinking restrictions (choice B) are not necessary for spirometry. 4. Using a rescue inhaler close to the test (choice C) can alter results. 5. Incentive spirometry (choice D) is not directly related to preparing for spirometry testing.
