A client with a history of asthma is prescribed salmeterol (Serevent). Which instruction should the nurse provide?

Correct Answer: C

Rationale: The correct instruction is C: Use this medication twice daily for long-term control. Salmeterol is a long-acting beta-agonist used for maintenance therapy in asthma to provide long-term control of symptoms and prevent exacerbations. It should not be used for acute asthma attacks as it does not provide quick relief like rescue inhalers such as albuterol (choice A). It is not meant to replace albuterol, so it should not be used before using albuterol (choice B). Using salmeterol as needed for wheezing (choice D) is not appropriate as it is a maintenance medication and not a rescue medication.

Correct Answer: B

Rationale: The correct answer is B because drinking a bowel preparation solution helps clear the colon for better visualization during the colonoscopy. This step is crucial to ensure accuracy of the procedure. Choice A is incorrect as the client should have a clear liquid diet the day before the procedure. Choice C is incorrect as hydration is important, but clear liquids are allowed. Choice D is incorrect because blood thinners may need to be adjusted prior to the procedure to reduce bleeding risk.

Correct Answer: C

Rationale: The correct answer is C: Take the medication on an empty stomach. Levothyroxine should be taken on an empty stomach in the morning, at least 30 minutes before eating, to ensure optimal absorption. Food can interfere with the absorption of levothyroxine, reducing its effectiveness. Taking it with a meal (option A) or at bedtime (option B) may lead to decreased absorption. Taking it with an antacid (option D) can also interfere with absorption. Therefore, the best instruction is to take the medication on an empty stomach to maximize its therapeutic effects.

Correct Answer: C

Rationale: The correct answer is C: Ensure the client's bladder is emptied regularly. Autonomic dysreflexia is a potentially life-threatening condition that occurs in clients with spinal cord injuries. It is triggered by a distended bladder or bowel. By regularly emptying the client's bladder, the nurse can prevent the stimulus that leads to autonomic dysreflexia. Option A is incorrect because restricting fluid intake can lead to dehydration, exacerbating the condition. Option B is incorrect as temperature regulation is not directly related to preventing autonomic dysreflexia. Option D is incorrect as high-fiber foods do not play a role in triggering this condition.

Correct Answer: D

Rationale: The correct answer is D: Decreased vital capacity. This finding indicates respiratory muscle weakness, which can lead to respiratory failure in Guillain-Barr© syndrome. Immediate action is needed to prevent respiratory compromise. Choice A is a common finding in Guillain-Barr© and does not require immediate action. Choice B is characteristic of Guillain-Barr© and should be monitored but not the most urgent. Choice C could indicate other issues but is not as critical as respiratory compromise.
