A nurse is preparing to administer Rosuvastatin 4000 mcg PO ac. Available: Rosuvastatin 2 mg tablet. How many tabs will the nurse administer? Round to the whole number. Use a leading zero if it applies. Do not use a trailing zero.
The Correct Answer is ["2"]
Understanding the problem
We need to administer 4000 mcg of Rosuvastatin.
The available tablets are 2 mg each.
We need to determine the number of tablets to administer.
Step-by-step calculation
Convert mcg to mg:
1 mg = 1000 mcg
4000 mcg = 4 mg
Calculate the number of tablets:
Number of tablets = Desired dose (mg) / Tablet strength (mg) = 4 mg / 2 mg/tablet = 2 tablets
Therefore, the nurse should administer 2 tablets of Rosuvastatin.

Correct Answer is ["1.2"]
Explanation
Step-by-step solution:
1. Convert pounds to kilograms:
1 lb = 0.453592 kg
33 lb x 0.453592 kg/lb = 14.97 kg
2. Calculate the total daily dose of digoxin:
Total daily dose = dose per kg/day x weight in kg = 8 mcg/kg/day x 14.97 kg = 119.76 mcg/day
3. Calculate the dose per administration:
Since the medication is divided into 2 doses per day,
Dose per administration = Total daily dose / number of doses = 119.76 mcg/day / 2 doses = 59.88 mcg/dose
4. Convert mcg to mg:
1 mg = 1000 mcg
59.88 mcg = 0.05988 mg
5. Calculate the volume to administer:
The medication concentration is 0.05 mg/mL.
Volume = Dose per administration / Concentration = 0.05988 mg / 0.05 mg/mL = 1.1976 mL
6. Round to the nearest tenth:
Volume = 1.2 mL
Therefore, the nurse should administer 1.2 mL of digoxin per dose.
Correct Answer is ["9.5"]
Explanation
We need to administer 475 mg of daptomycin.
The reconstituted solution has a concentration of 0.5 g/10 mL, which is equivalent to 50 mg/mL.
Calculation:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 475 mg / 50 mg/mL = 9.5 mL
Therefore, the nurse should administer 9.5 mL of the reconstituted daptomycin solution.
