Showing 10 questions, Sign in for moreA nurse is reviewing a new prescription with the parent of a newborn who is to receive ferrous sulfate 15 mg PO daily. Available is ferrous sulphate drops 75 mg/0.6 mL. How many mL should the parent administer to the newborn each day? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Calculation:
Prescribed dose = 15 mg
Available concentration = 75 mg per 0.6 mL
Calculate the volume in milliliters (mL) to administer per dose.
Volume (mL) = (Prescribed dose (mg) / Available concentration (mg)) x Available volume (mL)
= (15 mg / 75 mg) x 0.6 mL
= 0.2 x 0.6 mL
= 0.12 mL.
A nurse is preparing to administer enoxaparin 75 mg subcutaneous once daily to an antepartum client who has a clotting disorder. Available is enoxaparin injection 100 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:
Prescribed dose = 75 mg
Available concentration = 100 mg per 1 mL
Calculate the volume in milliliters (mL) to administer.
Volume (mL) = (Prescribed dose (mg) / Available concentration (mg)) x Available volume (mL)
= (75 mg / 100 mg) x 1 mL
= 0.75 x 1 mL
= 0.75 mL.
A nurse is caring for a client who is postpartum and has a prescription for oxytocin 10 units IM one time only for the saturation of a perineal pad in 15 min or less. How should the nurse interpret this prescription?
A nurse is preparing to administer dobutamine 10 mcg/kg/min by continuous IV infusion to a newborn who weighs 4 kg. Available is dobutamine 250 mg in 500 mL dextrose 5% in water. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Calculate the total dose of dobutamine to be administered per minute (mcg/min).
Ordered rate: 10 mcg/kg/min
Patient weight: 4 kg
Total dose rate (mcg/min) = 10 mcg/kg/min x 4 kg
= 40 mcg/min.
Calculate the total dose of dobutamine to be administered per hour (mcg/hr).
Total dose rate (mcg/hr) = 40 mcg/min x 60 min/hr
= 2400 mcg/hr.
Calculate the concentration of the available solution in micrograms per milliliter (mcg/mL).
Available concentration: 250 mg in 500 mL
Convert mg to mcg: 250 mg x 1000 mcg/mg = 250,000 mcg
Concentration (mcg/mL) = 250,000 mcg / 500 mL
= 500 mcg/mL
Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total dose rate (mcg/hr) / Concentration (mcg/mL)
= 2400 mcg/hr / 500 mcg/mL
= 4.8 mL/hr
A nurse is preparing to administer naloxone 0.2 mg IM for respiratory depression. Available is naloxone injection 0.4 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
Desired dose: 0.2 mg
Available concentration: 0.4 mg/mL
Calculate the volume to administer in milliliters (mL).
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
= 0.2 mg / 0.4 mg/mL
= 0.5 mL.
A nurse is preparing to administer procaine penicillin G 1,200,000 units IM to a client who has a gonococcal infection. Available is procaine penicillin G injection 600,000 units/mL. How many mL 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
Desired dose: 1,200,000 units
Available concentration: 600,000 units/mL
Calculate the volume to administer in milliliters (mL).
Volume (mL) = Desired Dose (units) / Available Concentration (units/mL)
= 1,200,000units/600,000units/mL
= 2mL.
A nurse is preparing to administer oxycodone 10 mg PO every 6 hr PRN for severe pain to a client who is postpartum following a cesarean birth. Available is oxycodone 5 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
Desired dose: 10 mg
Available dose: 5 mg/tablet
Calculate the number of tablets to administer per dose.
Number of tablets = Desired Dose (mg) / Available Dose (mg/tablet)
= 10 mg / 5 mg/tablet
= 2 tablets.
A nurse is caring for a newborn who weighs 3,500 g. The nurse should record the newborn's weight as how many kg? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Weight in grams: 3,500 g
Conversion factor: 1 kg = 1000 g
Calculate the weight in kilograms (kg).
Weight (kg) = Weight (g) / 1000 g/kg
= 3500 / 1000
= 3.5 kg
A nurse is reviewing instructions with a client who has a urinary tract infection and has a prescription to drink 2 L of fluid each day. How many oz of fluid should the nurse tell the client to drink each day? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Identify the total fluid volume in liters (L) and the conversion factor.
Fluid Volume: 2 L
Conversion factor: 1 Liter = 33.814 ounces (oz)
Calculate the fluid volume in ounces (oz).
Fluid Volume (oz) = Fluid Volume (L) x 33.814 oz/L
= 2L×33.814oz/L
= 67.628oz.
Round the answer to the nearest whole number.
= 68oz
A nurse in a prenatal clinic is caring for a client who has a new prescription for nystatin cream 100,000 units/g to the affected area. The nurse should recognize that which of the following elements of the prescription requires clarification by the provider?
