Showing 10 questions Sign up for moreA nurse is preparing to reconstitute amoxicillin/clavulanate oral suspension for a client. According to the medication label, what will the total volume of medication in the container be following reconstitution? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
The medication label clearly states that after reconstitution, the total volume of the suspension will be 75 mL. This means that once the correct amount of sterile water is added and the powder fully dissolves, the final usable volume of the medication will be 75 mL.
A nurse is preparing to administer diclofenac sodium 200 mg PO daily in equally divided doses every 6 hr. How many mg 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 total daily dose.
Total daily dose = 200 mg.
Determine the frequency of doses per day.
Doses per day = 24 hours / 6 hours/dose
= 4 doses.
Calculate the dose per administration.
Dose per administration = Total daily dose / Doses per day
= 200 mg / 4 doses
= 50 mg.
Rounded to the nearest whole number: 50.
A nurse is preparing to administer heparin 8,000 units subcutaneous to a client. Available is heparin injection 10,000 units/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
Calculation:
Identify the desired dose.
Desired dose = 8,000 units.
Identify the available concentration.
Available concentration = 10,000 units/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (units) / Available concentration (units/mL)
= 8,000 units / 10,000 units/mL
= 0.8 mL.
Rounded to the nearest tenth: 0.8.
A nurse is preparing to administer midazolam 7 mg IM 30 min prior to a procedure. Available is midazolam injection 5 mg/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
Calculation:
Identify the desired dose.
Desired dose = 7 mg.
Identify the available concentration.
Available concentration = 5 mg/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 7 mg / 5 mg/mL
= 1.4 mL.
Rounded to the nearest tenth: 1.4.
A nurse is preparing to administer enoxaparin 5 mg/kg subcutaneous to a client who weighs 187 lb. Available is enoxaparin 60 mg/0.6 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
Calculation:
Convert weight to kilograms.
Weight (kg) = 187 lb / 2.2 lb/kg
= 85 kg
Calculate the prescribed dose in milligrams.
Prescribed dose (mg) = 1.5 mg/kg × 85 kg
= 127.5 mg
Determine the concentration of the available enoxaparin.
Concentration = 60 mg / 0.6 mL
= 100 mg/mL
Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
= 127.5 mg / 100 mg/mL
= 1.275 mL
Round the answer to the nearest tenth.
= 1.3 mL
A nurse is preparing to administer methylprednisolone acetate 60 mg IM. Available is methylprednisolone acetate injection 80 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Calculation:
Identify the desired dose.
Desired dose = 60 mg.
Identify the available concentration.
Available concentration = 80 mg/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 60 mg / 80 mg/mL
= 0.75 mL.
Rounded to the nearest hundredth: 0.75.
A nurse is preparing to administer filgrastim 480 mcg subcutaneous daily. Available is filgrastim injection 300 mcg/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 desired dose.
Desired dose = 480 mcg.
Identify the available concentration.
Available concentration = 300 mcg/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (mcg) / Available concentration (mcg/mL)
= 480 mcg / 300 mcg/mL
= 1.6 mL.
Rounded to the nearest tenth: 1.6.
A nurse is reviewing a client's instructions for their prescribed medications. The nurse should identify that which of the following instructions contains household units?
Explanation
A. Take 250 mg by mouth twice daily: This instruction uses metric units (milligrams) to describe the medication dosage, not household measurement units.
B. Mix powder with 1 L of water and drink throughout the day: Liters are part of the metric system, commonly used in clinical settings, and do not represent household measurement units.
C. Dissolve one packet in 120 mL and drink twice daily: Milliliters are metric units. Although they may be converted for home use, they are not considered standard household units.
D. Take 1 Tbsp by mouth after every meal: This instruction uses a household unit—tablespoon (Tbsp)—which is commonly used everyday in medication instructions at home. One tablespoon is equal to 15 mL, making it a recognizable and practical measure for clients managing their medications outside of clinical settings.
A nurse is preparing to administer cefazolin 250 mg IM to a client. Available is cefazolin powder for injection 500 mg vial. The nurse reconstitutes the powder with 2 mL of sterile water for a concentration of 225 mg/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
Calculation:
Desired dose = 250 mg.
Available concentration after reconstitution = 225 mg/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 250 mg / 225 mg/mL
= 1.111... mL.
Step 4: Round the answer to the nearest tenth.
Rounded volume = 1.1 mL.
A nurse is preparing to administer cyanocobalamin 100 mcg IM monthly. Available is cyanocobalamin injection 1,000 mcg/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:
Desired dose = 100 mcg.
Available concentration = 1,000 mcg/mL.
Calculate the volume to administer.
Volume (mL) = Desired dose (mcg) / Available concentration (mcg/mL)
= 100 mcg / 1,000 mcg/mL
= 0.1 mL.
Rounded to the nearest tenth: 0.1.
