Correct Answer: B

Rationale: The correct intervention for a client with pneumonia is to perform chest percussion every 4 hours. Chest percussion helps loosen secretions and improve airway clearance in clients with pneumonia. Placing the client in the supine position can worsen breathing, so it is incorrect. Administering oxygen via nasal cannula is a common intervention for clients with respiratory issues but is not specific to pneumonia. Limiting fluid intake to 1,500 mL/day may not be appropriate as pneumonia can lead to dehydration, so it is not the priority intervention.

Correct Answer: B

Rationale: The correct answer is B. Eating more leafy green vegetables can increase vitamin K intake, which may reduce the effectiveness of warfarin. This can lead to fluctuations in the International Normalized Ratio (INR) levels, affecting the medication's efficacy. Choices A, C, and D are correct statements. Taking warfarin every other day, using a soft toothbrush to prevent gum bleeding, and having regular INR checks are all appropriate and important actions when taking warfarin.

Correct Answer: A

Rationale: The correct answer is A: Administer analgesics regularly. Postoperative pain management often requires a scheduled, around-the-clock administration of analgesics to maintain a consistent level of pain relief and minimize the risk of breakthrough pain. Choice B, administering pain medication PRN (as needed), may lead to inadequate pain control as the medication is not given preemptively. Choice C, encouraging deep breathing exercises, can be beneficial for pain management but should be used as an adjunct to analgesic therapy. Choice D, providing distraction techniques, may help some patients cope with pain but should not be the primary method of pain management postoperatively.

Correct Answer: A

Rationale: The correct answer is to administer bronchodilators as the priority nursing intervention for a patient with an acute asthma attack. Bronchodilators help open the airways and improve airflow, which is crucial in managing acute asthma symptoms. Administering corticosteroids (Choice B) is also important in the treatment plan, but it is not the priority intervention during an acute attack. Providing supplemental oxygen (Choice C) may be necessary but is not the priority initial intervention. Starting IV fluids (Choice D) is not typically indicated as a priority intervention for an acute asthma attack.

Correct Answer: A

Rationale: Corrected Rationale: Changing the central line dressing daily is crucial in preventing infection at the insertion site. This practice helps maintain a clean and sterile environment around the central line, reducing the risk of pathogens entering the bloodstream. Monitoring for redness (choice B) is important but may not directly prevent infection. Checking the central line site every shift (choice C) is essential for early detection of any issues but does not solely prevent infection. Flushing the line with saline (choice D) is a necessary procedure for maintaining central line patency but does not primarily prevent infection.
