A cancer client who weighs 70 kg is scheduled for chemotherapy. A nurse has to administer ondansetron 0.34 mg/kg, 30 minutes prior. What is the dose of ondansetron this client should receive?
23 mg
6.8 mg
23.8 mg
20.59 mg
The Correct Answer is C
To calculate the dose of ondansetron for this client, we need to use the client's weight and the prescribed dose of 0.34 mg/kg.
The formula to calculate the dose is:
Dose (in mg) = Weight (in kg) x Dose (in mg/kg) So, for this client:
Dose (in mg) = 70 kg x 0.34 mg/kg
Dose (in mg) = 23.8 mg (rounded to one decimal place)
Therefore, the client should receive a dose of 23.8 mg of ondansetron, 30 minutes prior to chemotherapy.

Correct Answer is C
Explanation
To calculate the dose that the child receives, we need to first convert the volume of the suspension from teaspoons to milliliters. One teaspoon is equal to 5 milliliters, so 2 teaspoons is equal to 10 milliliters. Then, we can use the concentration of the suspension to find the amount of cefuroxime in 10 milliliters. The concentration is 25 mg in 2 mL, or 12.5 mg in 1 mL. Therefore, the amount of cefuroxime in 10 mL is:
10 mL × 12.5 mg/mL = 125 mg
Therefore, the child receives 125 mg of cefuroxime once a day orally.
Correct Answer is A
Explanation
Administer one half tablet. To find the amount of tablets to administer, use the formula: (ordered dose / available dose). In this case, (250 mg / 500 mg) = 0.5 tablet. Since the tablet is pre-scored, it can be easily split in half.
Metformin is a medication that belongs to a class of drugs called biguanides. It is used to treat type 2 diabetes by lowering blood sugar levels and improving insulin sensitivity. Metformin works by reducing the amount of glucose produced by the liver and increasing the uptake of glucose by the muscles and other tissues.
Metformin can also help prevent or delay the onset of diabetes complications, such as heart disease and kidney damage.
