A nurse is preparing to administer ciprofloxacin 0.5 g PO to a client who has a postpartum infection. Available is ciprofloxacin 250 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 administer the correct dose of ciprofloxacin, which is 0.5 grams (g), the nurse needs to convert this amount into milligrams (mg) because the available tablets are measured in mg. There are 1000 mg in 1 g, so 0.5 g is equal to 500 mg. Since each tablet contains 250 mg, the nurse would need to administer two tablets to reach the prescribed dose of 500 mg.

Correct Answer is ["12.2"]
Explanation
To calculate the IV pump setting, first convert the newborn's weight from pounds to kilograms, knowing that 1 pound is equivalent to 0.453592 kilograms. The newborn weighs 6.7 pounds, which is approximately 3.039 kg (6.7 lb * 0.453592 kg/lb). Next, calculate the total amount of potassium needed per hour by multiplying the newborn's weight in kilograms by the prescribed dose: 0.4 mEq/kg/hr * 3.039 kg = 1.2156 mEq/hr. Since the available potassium is 10 mEq in 100 mL, this means there is 0.1 mEq/mL. To find out how many mL/hr to administer, divide the total mEq needed per hour by the concentration: 1.2156 mEq/hr ÷ 0.1 mEq/mL = 12.156 mL/hr. Rounded to the nearest tenth, the IV pump should be set to deliver 12.2 mL/hr.
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.
