(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Calculation:
- Identify the ordered dose and tablet strength
Ordered Dose: 100 mcg
Tablet Strength: 50 mcg per tablet
- Calculate the number of tablets to administer
Number of Tablets = Ordered Dose ÷ Tablet Strength
Number of Tablets = 100 ÷ 50
= 2
A nurse is caring for a client who is receiving heparin 3,800 units subcutaneous daily. Available is heparin 5,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth.)
Explanation
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 3,800 units
Available Concentration: 5,000 units/mL
- Calculate the volume to administer
Volume to administer = Ordered Dose ÷ Concentration
Volume to administer = 3,800 ÷ 5,000
Volume to administer = 0.76 mL
- Round to the nearest tenth
= 0.8 mL
A nurse is preparing to instill 840 mL of enteral nutrition via a client's gastrostomy tube over 24 hr using an infusion pump. The nurse should set the infusion 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
Calculation:
- Identify the total volume and infusion time
Total Volume: 840 mL
Infusion Time: 24 hours
- Calculate the infusion rate
Infusion Rate (mL/hr) = Total Volume ÷ Time
Infusion Rate = 840 ÷ 24
= 35 mL/hr
A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 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
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 2 mg
Available Concentration: 10 mg/mL
- Calculate the volume to administer
Volume to administer = Ordered Dose ÷ Concentration
Volume to administer = 2 ÷ 10
= 0.2 mL
nurse is caring for a client who is to receive liquid medications via a gastrostomy tube. The client is prescribed phenytoin 250 mg. The amount available is phenytoin oral solution 25 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 250 mg
Available Concentration: 25 mg/5 mL
- Calculate the volume to administer
Volume to administer = (Ordered Dose ÷ Concentration) × Volume of Concentration
Volume to administer = (250 ÷ 25) × 5
Volume to administer = 10 × 5
= 50 mL
A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily. Available is digoxin 0.125 mg/tab. How many tablets 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
Calculation:
- Identify the ordered dose and tablet strength
Ordered Dose: 0.25 mg
Tablet Strength: 0.125 mg per tablet
- Calculate the number of tablets to administer
Number of Tablets = Ordered Dose ÷ Tablet Strength
Number of Tablets = 0.25 ÷ 0.125
= 2
A nurse is preparing to administer aspirin 650 mg PO every 12 hr. The amount available is aspirin 325 mg tablets. How many tablets 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
Calculation:
- Identify the ordered dose and tablet strength
Ordered Dose: 650 mg
Tablet Strength: 325 mg per tablet
- Calculate the number of tablets to administer
Number of Tablets = Ordered Dose ÷ Tablet Strength
Number of Tablets = 650 ÷ 325
= 2
A nurse is preparing to administer hydrocortisone 100 mg IM daily to a client. Available is hydrocortisone 250 mg/2 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 100 mg
Available Concentration: 250 mg/2 mL
- Calculate the volume to administer
First determine mg per mL:
250 mg ÷ 2 mL = 125 mg/mL
Volume to administer = Ordered Dose ÷ Concentration
Volume to administer = 100 ÷ 125
= 0.8 mL
A nurse is preparing to administer 250 mg of an antibiotic IM. Available is 3 g/5 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
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 250 mg
Available Concentration: 3 g/5 mL (3,000 mg/5 mL)
- Calculate the concentration per mL
Concentration = 3,000 mg ÷ 5 mL
Concentration = 600 mg/mL
- Calculate the volume to administer
Volume to administer = Ordered Dose ÷ Concentration
Volume to administer = 250 ÷ 600
Volume to administer = 0.42 mL
- Round to the nearest tenth
= 0.4 mL
A nurse is preparing to administer atenolol 25 mg PO every 12 hr. The amount available is atenolol 50 mg/tab. How many tablets 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
Calculation:
- Identify the ordered dose and tablet strength
Ordered Dose: 25 mg
