A nurse is preparing to administer ondansetron 0.15 mg/kg IV to child who is receiving chemotherapy and weighs 29.4 kg. Available is ondansetron 4 mg/2 mL solution.

How many mL should the nurse administer?

Answer and Explanation

The Correct Answer is ["2.2"]

Step 1 is to calculate the total dose of ondansetron required. This is done by multiplying the child’s weight by the dose per kilogram. So, 29.4 kg × 0.15 mg/kg = 4.41 mg.

Step 2 is to calculate the volume of the solution required. This is done by dividing the total dose by the concentration of the solution. So, 4.41 mg ÷ (4 mg/2 mL) = 2.205 mL. The final calculated answer is that the nurse should administer approximately 2.2 mL of the ondansetron solution.

Correct Answer is B

Explanation

Choice A rationale

Consuming flavored yogurt instead of plain yogurt may not be beneficial for a lactose intolerant individual. Flavored yogurts often contain added sugars and may still contain lactose, which can trigger symptoms in individuals with lactose intolerance.

Choice B rationale

Replacing milk with non-dairy sources of calcium is a common strategy for managing lactose intolerance. Non-dairy sources of calcium include foods like broccoli, oranges, almonds, tofu, and certain fortified products. This can help ensure the individual meets their calcium needs without triggering symptoms of lactose intolerance.

Choice C rationale

Drinking milk on an empty stomach is not typically recommended for individuals with lactose intolerance. Consuming lactose-containing foods or drinks on an empty stomach may increase the likelihood of experiencing symptoms.

Choice D rationale

The tolerance for plain milk versus chocolate milk can vary among individuals with lactose intolerance. However, chocolate milk often contains added sugars and may still contain lactose, which can trigger symptoms.
