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
- Convert ounces to milliliters (mL):
-
1 ounce (oz) is approximately equal to 30 mL.
-
Orange juice: 12 oz * 30 mL/oz = 360 mL
-
Ice chips: 12 oz * 30 mL/oz = 360 mL (Note: Ice melts to about half its volume, so we'll divide this by 2 later)
-
Coffee: 6 oz * 30 mL/oz = 180 mL
-
Skim milk: 4 oz * 30 mL/oz = 120 mL
-
Water: 24 oz * 30 mL/oz = 720 mL
- Account for ice chips melting:
- Ice chips: 360 mL / 2 = 180 mL
- Add up all the fluid intake in mL:
- Orange juice: 360 mL
- Ice chips: 180 mL
- Coffee: 180 mL
- Skim milk: 120 mL
- Water: 720 mL
- IV fluid: 1000 mL
Total: 360 + 180 + 180 + 120 + 720 + 1000 = 2560 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.]
