Correct Answer: B

Rationale: The correct answer is B: Bananas. Bananas are high in potassium, which helps counter the potassium-depleting effects of furosemide. Furosemide is a loop diuretic that can lead to potassium loss, so including potassium-rich foods like bananas in the diet can help maintain a healthy potassium level. Choices A, C, and D do not specifically address the potassium needs associated with furosemide therapy and are not the most appropriate recommendations in this context.

Correct Answer: C

Rationale: The correct answer is C: Potassium. Furosemide is a diuretic that can cause potassium depletion due to increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Sodium (choice A) levels are not typically affected by furosemide. Glucose (choice B) monitoring is important with other medications like corticosteroids but is not directly related to furosemide use. Calcium (choice D) levels are not significantly impacted by furosemide.

Correct Answer: A

Rationale: Corrected Rationale: Viral infections often cause fatigue and body aches, while bacterial infections are more likely to cause high fever and localized pain. Choice A is the correct answer as it accurately reflects the symptoms commonly associated with viral infections. Bacterial infections, on the other hand, typically present with fever and localized pain, as stated in choice B. Choice C is incorrect as viral infections do not respond to antibiotics, while choice D is inaccurate because bacterial infections may require antibiotic treatment and are not always self-limiting.

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.
