Available is ticarcillin clavulanate 3.1 g in 150 ml 0.9% sodium chloride (NSS). The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)
Explanation
Understanding the problem
We need to administer 150 mL of the medication over 30 minutes.
We need to determine the flow rate in mL/hr.
Step-by-step calculation
Convert minutes to hours:
30 minutes = 0.5 hours
Calculate the flow rate:
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours) = 150 mL / 0.5 hours = 300 mL/hr
Therefore, the nurse should set the IV pump to deliver 300 mL/hr.
A nurse is preparing to administer tobramycin 3 mg/kg/day IM divided in three equal doses to a client who weighs 50 kg. Available is tobramycin 40 mg/mL How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
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
A nurse is calculating the total fluid intake for a client on strict 180; during your shift the client had 12 oz of orange juice, 12 oz of ice chips, 6 oz of coffee with 4 oz of skim milk, 24 oz of water, and 1000 mL of IV fluid infusion. What was the client's total intake for your shift?
Explanation
Understanding the problem
We need to calculate the total fluid intake in mL.
We have various fluids in different units (oz and mL).
Step-by-step calculation
Convert ounces to milliliters:
1 oz = 30 mL
Orange juice: 12 oz x 30 mL/oz = 360 mL
Ice chips: 12 oz x 30 mL/oz = 360 mL
Coffee: 6 oz x 30 mL/oz = 180 mL
Skim milk: 4 oz x 30 mL/oz = 120 mL
Water: 24 oz x 30 mL/oz = 720 mL
Calculate the total fluid intake:
Total intake = Orange juice + Ice chips + Coffee + Skim milk + Water + IV fluid = 360 mL + 360 mL + 180 mL + 120 mL + 720 mL + 1000 mL = 2740 mL
Therefore, the client's total fluid intake for the shift was 2740 mL.
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.
Explanation
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.
A nurse is preparing to administer digoxin 8 mg/kg/day PC divided equally every 12 hr for a preschooler who weighs 33 b. Available is digoxin elixir 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero If it applies. Do not use a trailing zero.
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.
A nurse is preparing to administer daptomycin 475 mg IV bolus. The nurse reconstitutes a vial of daptomycin to yield a final concentration of 0.5 g/10 ml How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
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.
A nurse is preparing to administer nafcillin 2 g IV bolus. The nurse reconstitutes a vial of nafcillin to yield a final concentration of 250 mg/ml. How many m should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Understanding the problem
We need to administer 2g of nafcillin.
The reconstituted solution has a concentration of 250 mg/mL.
We need to determine the volume to administer.
Step-by-step calculation
Convert grams to milligrams:
2 g = 2000 mg
Use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 2000 mg / 250 mg/mL
Calculate the volume:
Volume (mL) = 8 mL
Therefore, the nurse should administer 8 mL of the reconstituted nafcillin solution.
A nurse is preparing to administer furosemide 30 mg IM. Available is furosemide injection 10mg/ml. How many ml should the nurse administer? (Round the answer to the whole number. Use a leading zero if it applies. Do not use a trailing zero.]
