Correct Answer: D

Rationale: Dehydration management involves a comprehensive approach that includes monitoring fluid intake to assess the severity of dehydration, encouraging oral rehydration to replenish fluids orally if the patient can tolerate it, and administering IV fluids in severe cases where oral intake is insufficient. Choosing just one of these options may not address the diverse needs of patients with dehydration. Therefore, selecting 'All of the above' is the most appropriate response as it encompasses the various strategies required for effective dehydration management.

Correct Answer: C

Rationale: When dealing with a physically assaultive client, the initial priority is to focus on restoring the client's self-control and preventing further escalation. Restricting the client to the room (choice A) may escalate the situation and is not the initial priority. Placing the client under one-to-one supervision (choice B) is important but comes after ensuring the client's self-control. Clearing the immediate area of other clients (choice D) is essential for safety but is not the initial priority when compared to restoring the client's self-control.

Correct Answer: B

Rationale: When a client develops phlebitis at the IV site, the nurse's immediate action should be to discontinue the IV and notify the healthcare provider. Phlebitis is inflammation of the vein, and leaving the IV in place can lead to complications such as infection or thrombosis. Administering an anti-inflammatory medication (choice A) may not address the root cause and delay the necessary intervention. Applying a cold compress (choice C) may provide temporary relief but does not address the need to remove the source of inflammation. Increasing the IV flow rate (choice D) is contraindicated as it can exacerbate the phlebitis by causing more irritation to the vein.

Correct Answer: A

Rationale: The correct answer is A: Hypertension, high cholesterol, and smoking are major risk factors for stroke. These factors contribute to the development of atherosclerosis, which can lead to a stroke. While obesity and lack of exercise are risk factors for cardiovascular diseases, they are not as directly linked to stroke as hypertension, high cholesterol, and smoking. Family history of cardiovascular disease may increase the overall risk of heart problems, but it is not as specific to stroke as the factors listed in option A. Age and gender can influence the risk of stroke, but they are not modifiable risk factors like hypertension, high cholesterol, and smoking, which can be reduced through lifestyle changes.

Correct Answer: A

Rationale: The correct answer is A. In older adults, key signs of a UTI often include confusion and increased temperature. Confusion is a common symptom in the elderly when they have a UTI, and an increase in body temperature can indicate an infection. Choices B, C, and D are incorrect because while painful urination and frequent urination are common UTI symptoms in general, they may not be as prominent in older adults. Dizziness, headache, back pain, and fever can be associated with other conditions but are not typically key signs of a UTI in older adults.
