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 ["1.3"]
Explanation
Step-by-step solution:
1. Calculate the total daily dose:
Total daily dose = dose per kg/day x weight in kg = 3 mg/kg/day x 50 kg = 150 mg/day
2. Calculate the dose per administration:
Since the medication is divided into 3 doses per day,
Dose per administration = Total daily dose / number of doses = 150 mg/day / 3 doses = 50 mg/dose
3. Calculate the volume to administer:
The medication concentration is 40 mg/mL.
Volume = Dose per administration / Concentration = 50 mg / 40 mg/mL = 1.25 mL
4. Round to the nearest tenth:
Volume = 1.3 mL
Therefore, the nurse should administer 1.3 mL of tobramycin per dose
Correct Answer is ["1.7"]
Explanation
Let's calculate the lorazepam dose
Step-by-step solution:
1. Convert pounds to kilograms:
1 lb = 0.453592 kg
150 lb x 0.453592 kg/lb = 68.04 kg
2. Calculate the total dose of lorazepam:
Dose = 0.05 mg/kg x 68.04 kg = 3.402 mg
3. Calculate the volume to administer:
The medication concentration is 2 mg/mL.
Volume = Total dose / Concentration = 3.402 mg / 2 mg/mL = 1.701 mL
4. Round to the nearest tenth:
Volume = 1.7 mL
Therefore, the nurse should administer 1.7 mL of lorazepam.
