A nurse is preparing to administer acetaminophen 0.65 g PO to a client for a report of postpartum pain. Available is acetaminophen 325 mg tablets. How many tablets should the nurse plan to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
To convert grams to milligrams, the value in grams is multiplied by 1,000. Therefore, 0.65 grams of acetaminophen is equivalent to 650 milligrams. If one tablet contains 325 milligrams, the number of tablets needed would be 650 mg divided by 325 mg per tablet, which equals 2.

Correct Answer is ["2"]
Explanation
To administer the correct dose of ondansetron, which is 4 mg intramuscularly, the nurse needs to calculate the volume of ondansetron injection required based on the concentration provided. The available ondansetron injection has a concentration of 2 mg/mL. To find the volume needed to deliver 4 mg, the nurse should divide the ordered dose by the concentration of the drug: 4 mg divided by 2 mg/mL equals 2 mL.
Correct Answer is ["105"]
Explanation
To calculate the IV pump setting, we need to convert the dosage from mg/min to mg/hr, and then find out how many mL/hr this corresponds to, given the concentration of the solution. First, multiply the ordered dose by 60 minutes to convert to an hourly rate: 7 mg/min * 60 min/hr = 420 mg/hr. Next, since we have 1 g of lidocaine in 250 mL, we convert 1 g to mg, which is 1000 mg. Now, we have 1000 mg in 250 mL, so we need to find out how many mL are needed for 420 mg. Using a proportion, we have 1000 mg/250 mL = 420 mg/x mL. Solving for x gives us x = (420 mg * 250 mL) / 1000 mg, which equals 105 mL. Therefore, the nurse should set the IV pump to deliver 105 mL/hr.
