Correct Answer: B

Rationale: The correct answer is B. Regular exercise and maintaining a healthy weight are crucial lifestyle changes in managing hypertension. Exercise helps lower blood pressure and improves heart health, while maintaining a healthy weight reduces the risk of hypertension. Choices A, C, and D are incorrect. Increasing daily intake of sodium can elevate blood pressure, reducing intake of potassium-rich foods is not recommended as potassium helps lower blood pressure, and drinking alcohol should be limited or avoided as it can raise blood pressure.

Correct Answer: B

Rationale: In this scenario, the nurse should first start an intravenous fluid bolus. This intervention is crucial in addressing severe dehydration associated with diabetic ketoacidosis, a life-threatening complication of type 1 diabetes. Administering intravenous insulin (Choice A) is important but should follow fluid resuscitation. Obtaining a blood glucose level (Choice C) is necessary but not as urgent as addressing the dehydration. Administering an antiemetic (Choice D) is not the priority in this situation.

Correct Answer: D

Rationale: The correct answer is D because tasks like applying and caring for a client's rectal pouch are within the UAP's scope of practice, as they do not require clinical judgment. Choices A, B, and C involve more complex assessments or interventions that require clinical judgment and should be performed by licensed nursing staff.

Correct Answer: B

Rationale: Administering antiemetics before meals is the best intervention to manage nausea and vomiting in clients receiving chemotherapy. This proactive approach helps control symptoms by preventing nausea from occurring, rather than waiting to treat it once symptoms have already started. Offering frequent, small meals (choice A) may worsen symptoms in some cases due to increased stomach activity. Encouraging a high-fat diet (choice C) can be difficult for nauseated clients and may not alleviate symptoms. Providing cold, carbonated beverages (choice D) could exacerbate nausea further due to the temperature and carbonation.

Correct Answer: D

Rationale: The UAP can be tasked with reporting complaints, monitoring weight gain, and tracking food and fluid intake, all of which are important in managing a client with Cushing's syndrome. These tasks fall within the UAP's scope of practice. Reporting client complaints helps in early identification of complications, monitoring weight is crucial due to fluid retention in Cushing's syndrome, and tracking food and fluid intake assists in dietary management. Choices A, B, and C are all necessary components of care for a client with Cushing's syndrome, making option D the correct answer.
