A nurse is calculating the intake of a client during the past 9 hours.

The client's intake includes:

Lactated Ringer's IV at 150 mL/hr

cefazolin 2 g IV intermittent bolus in 100 mL of 0.9% sodium chloride

two units of packed RBCs of 275 mL and 250 mL

two IV bolus infusions of 250 mL of 0.9% sodium chloride

ranitidine 50 mg IV intermittent bolus in 50 mL of dextrose 5% in water.

How many mL of intake should the nurse record?

Answer and Explanation

The Correct Answer is ["2525"]

Step 1 is calculate intake from lactated Ringer’s: 150 mL/hr × 9 hrs = 1350 mL.

Step 2 is calculate cefazolin intake: 100 mL × 1 dose = 100 mL.

Step 3 is calculate intake from two units of packed RBCs: 275 mL + 250 mL = 525 mL.

Step 4 is calculate intake from two IV boluses: 250 mL × 2 = 500 mL.

Step 5 is calculate intake from ranitidine infusion: 50 mL × 1 dose = 50 mL.

Step 6 is calculate total intake: 1350 mL + 100 mL + 525 mL + 500 mL + 50 mL = 2525 mL. Final calculated intake is 2525 mL.

Correct Answer is A

Explanation

Choice A rationale

A ketogenic diet includes high fats, moderate protein, and low carbohydrates, with unsaturated fats emphasized for health. This metabolic state reduces seizure frequency by enhancing ketone production as an alternative energy source for the brain.

Choice B rationale

Increasing carbohydrates disrupts ketosis, the fundamental principle of the ketogenic diet. This would counteract the therapeutic goal of reducing seizure activity by providing glucose as a primary brain fuel instead of ketones.

Choice C rationale

While omega-3 oils support brain health, the ketogenic diet focuses on low carbohydrate intake and high fat. Moderate protein intake is essential, but excess omega-3 emphasis neglects the diet’s structure.

Choice D rationale

Foods high in sodium and carbohydrates contradict the ketogenic diet's principles. Elevated carbohydrate intake halts ketosis, while excess sodium intake is unrelated to ketogenic mechanisms or seizure management.

Correct Answer is ["0.1"]

Explanation

Step 1 is (225 mcg ÷ 1000 mcg) × 0.50 tablets.

Answer is 0.1 tablets.
