The physician orders strict I & O for a critically ill patient with CHF on a furosemide drip.
The RN knows that it would be appropriate to ask the physician for an order to place a Foley catheter for this patient.
True.
False.
The Correct Answer is A
Choice A rationale
Strict monitoring of intake and output in CHF patients with furosemide therapy prevents fluid overload and underhydration. Foley catheter placement accurately quantifies urine output, crucial in critically ill patients with diuretic-induced fluid shifts. This ensures precise fluid balance adjustments, improving patient outcomes.
Choice B rationale
Omitting Foley catheter placement in CHF patients risks inaccurate fluid balance monitoring. Furosemide causes frequent, unpredictable urination, complicating intake-output tracking without direct measurement. This approach undermines effective management of diuretic therapy and fluid overload prevention in critical settings. .

Correct Answer is D
Explanation
Choice A rationale
Administering dextrose IVP is inappropriate for hyperglycemia. It elevates blood sugar further, risking complications like hyperosmolar hyperglycemic state. It is used to treat severe hypoglycemia instead.
Choice B rationale
Glucagon stimulates glycogen breakdown into glucose, increasing blood sugar. It is contraindicated in hyperglycemia, as it would aggravate elevated glucose levels. It is a treatment for severe hypoglycemia.
Choice C rationale
Holding insulin allows hyperglycemia to persist, increasing risks of complications like ketoacidosis. Insulin administration is essential to reduce the glucose level safely.
Choice D rationale
Rapid-acting insulin like Humalog reduces hyperglycemia efficiently, bringing preprandial blood glucose closer to the target range of 70-130 mg/dL. Administering 4 units is a reasonable corrective dose based on the blood glucose of 243 mg/dL.
Correct Answer is B
Explanation
Choice A rationale
Estimating carbohydrate content rather than measuring can lead to inaccuracies in blood sugar control for diabetic patients. Precise carbohydrate counting is essential for maintaining glycemic control and preventing hyperglycemia or hypoglycemia, making this approach unsuitable in diabetes education.
Choice B rationale
Balancing carbohydrate intake with insulin or medication is a critical aspect of diabetes management. This ensures stable blood glucose levels as insulin dosage or medication is adjusted according to the patient's carbohydrate consumption, providing personalized glycemic control effectively.
Choice C rationale
Avoiding all carbohydrates is not a realistic or scientifically sound recommendation, as carbohydrates are essential for energy production. Teaching portion control and healthy carbohydrate choices is more effective for diabetic management than complete avoidance.
Choice D rationale
Counting carbohydrates from sugary foods alone ignores the contribution of complex carbohydrates to blood glucose levels. A comprehensive approach that considers all sources of carbohydrates ensures accurate diabetes education and better long-term blood sugar control.
