Correct Answer: B

Rationale: Encouraging stretching exercises is the most appropriate nursing intervention to help a patient with chronic pain maintain mobility. Stretching exercises can improve flexibility, prevent stiffness, and promote better range of motion in patients with chronic pain. Providing opioids (Choice A) may help control pain but does not directly address mobility. Teaching the patient to use assistive devices (Choice C) may be beneficial but does not focus on improving mobility directly. Recommending complete bed rest (Choice D) can lead to deconditioning and further loss of mobility, which is not recommended for chronic pain management.

Correct Answer: B

Rationale: Administering oxygen via nasal cannula as prescribed is the most appropriate action to improve the patient's oxygenation in COPD. Oxygen therapy helps maintain adequate oxygen levels in the blood, which is crucial for managing COPD. Encouraging the use of incentive spirometry, assisting with coughing and deep breathing exercises, and positioning the patient in high Fowler's position are all beneficial interventions, but administering oxygen is the priority for immediate oxygenation support in COPD.

Correct Answer: B

Rationale: The correct answer is to contact the stoma nurse to assist the client with care. Stoma nurses are specially trained to provide guidance on stoma care, especially for clients with new ostomies. Instructing the client to care for the stoma independently (Choice A) may not be appropriate initially as they may need professional guidance. Delegating the care of the stoma to a nursing assistant (Choice C) is not recommended as specialized care is required. Waiting until the next shift (Choice D) is not ideal as stoma care should not be delayed.

Correct Answer: B

Rationale: Administering oxygen at 2 liters per minute via nasal cannula is the immediate action for a patient experiencing shortness of breath. This intervention helps to improve oxygenation and relieve respiratory distress promptly. Placing the patient in a high Fowler's position (choice A) may also be beneficial but providing oxygen takes precedence in this scenario to address the underlying hypoxemia. Encouraging deep breaths and coughing (choice C) may not be appropriate as the first action, especially without assessing the patient first. Assessing lung sounds (choice D) is essential but should follow the initial intervention of administering oxygen.

Correct Answer: B

Rationale: The correct answer is B: 'Flush the NG tube before and after each medication.' Flushing the NG tube is essential to ensure that the medication passes through smoothly without any obstruction. It helps prevent clogging of the tube and ensures that the full dose of the medication reaches the patient. Options A, C, and D are incorrect because crushing all medications at once, administering only liquid forms of medications, and skipping tube flushing entirely can lead to complications such as tube blockages, incomplete medication administration, and potential harm to the client.
