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 ["2"]
Explanation
To administer a dose of 10 mg of oxycodone when only 5 mg tablets are available, the nurse would need to give two (2) tablets to achieve the required dose. This is because each tablet contains 5 mg, and two tablets would make up the 10 mg dose that has been prescribed.
Correct Answer is ["1.7"]
Explanation
To calculate the IV pump setting, first determine the total micrograms of dopamine needed per minute for the newborn: 5 mcg/kg/min * 4.4 kg = 22 mcg/min. Next, convert the available dopamine concentration to micrograms: 200 mg * 1000 mcg/mg = 200,000 mcg. Now, calculate how many micrograms are in each mL of the solution: 200,000 mcg / 250 mL = 800 mcg/mL. Then, determine how many mL are needed per minute to deliver the required 22 mcg/min: 22 mcg/min / 800 mcg/mL = 0.0275 mL/min. Finally, convert this to an hourly rate: 0.0275 mL/min * 60 min/hr = 1.65 mL/hr. Rounded to the nearest tenth, the IV pump should be set to deliver 1.7 mL/hr.
