Correct Answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps improve oxygenation by preventing airway collapse, slowing down the breathing rate, and promoting better gas exchange. Administering oxygen at 2L/min via nasal cannula is not the first-line intervention as it can cause oxygen toxicity in COPD patients. Positioning the client in high Fowler's position may improve ventilation but does not specifically address the breathing technique required for COPD. Encouraging deep breathing and coughing is generally not recommended for clients with COPD as it can lead to air trapping and increased work of breathing.

Correct Answer: B

Rationale: The correct instruction the nurse should include is to 'Rest as needed throughout the day.' Fatigue is a common symptom of multiple sclerosis (MS), and adequate rest is essential to manage it effectively. Resting as needed helps conserve energy and prevent fatigue from worsening. Choices A, C, and D are incorrect. 'Exercise to the point of exhaustion' is not recommended as it can lead to increased fatigue. 'Avoiding physical activity' entirely is not advisable as appropriate exercise can help maintain strength and energy levels. 'Exercising only once per week' may not be sufficient to combat fatigue and maintain overall well-being in clients with MS.

Correct Answer: D

Rationale: The correct answer is to pour warm water over the client's perineum. This action helps stimulate voiding post-catheterization by promoting relaxation and providing sensory input. Assessing for bladder distention after 6 hours (Choice A) is important but not the immediate intervention needed for difficulty voiding. Encouraging the client to use a bedpan in the supine position (Choice B) may not effectively address the issue of post-catheterization voiding difficulty. Restricting the client's intake of oral fluids (Choice C) is not appropriate and can lead to dehydration, which is not helpful in promoting voiding.

Correct Answer: B

Rationale: Increasing dietary fiber is an effective recommendation for clients experiencing constipation as it helps promote regular bowel movements. Choice A, increasing fluid intake, is also important but the most appropriate initial recommendation for constipation is to increase dietary fiber. Choice C, administering a laxative, should not be the first-line recommendation and is typically considered after dietary and lifestyle interventions. Choice D, encouraging bed rest, does not directly address constipation relief or prevention.
