A nurse is preparing to administer calcitonin 8 units/kg IM to a client who weighs 130 lb. Available is calcitonin 200 units/ml. for injection. 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.)

Full Explanation
To calculate the amount of calcitonin the nurse should administer, follow these steps:
Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2 Weight in kilograms = 130 lb / 2.2 = 59.09 kg (rounded to two decimal places)
Calculate the total units of calcitonin needed: Total units = Weight in kilograms × Dose per kilogram Total units = 59.09 kg × 8 units/kg = 472.72 units
Determine the volume (ml) to administer using the concentration of the available calcitonin: Volume (ml) = Total units needed / Concentration (units/ml) Volume (ml) = 472.72 units / 200 units/ml = 2.36 ml
Rounded to the nearest tenth of a milliliter, the nurse should administer 2.4 ml of calcitonin.

A nurse is preparing to administer lisinopril 2.5 mg PO to an older adult client. Available is lisinopril 5 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
To calculate how many tablets of lisinopril 5 mg the nurse should administer to achieve a 2.5 mg dose, divide the desired dose by the dose per tablet:
Number of tablets = Desired dose / Dose per tablet
Number of tablets = 2.5 mg / 5 mg/tablet
Number of tablets = 0.5 tablets
A nurse is preparing to administer gentamicin 5 mg/kg via intermittent IV bolus to a client who weighs 210 lb. The amount available is gentamicin 10 mg/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.)
Full Explanation
To calculate how many milliliters (ml) of gentamicin to administer, follow these steps:
Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2
Weight in kilograms = 210 lb / 2.2 Weight in kilograms ≈ 95.45 kg
Determine the dose based on the weight: Dose = 5 mg/kg × Weight in kilograms Dose = 5 mg/kg × 95.45 kg Dose ≈ 477.25 mg
Check the concentration of the available gentamicin: Concentration = 10 mg/mL
Calculate the volume (ml) to administer: Volume (ml) = Dose (mg) / Concentration (mg/ml) Volume (ml) = 477.25 mg / 10 mg/ml Volume (ml) ≈ 47.73 ml
Rounded to the nearest whole number, the nurse should administer approximately 48 ml of gentamicin.
A nurse is preparing to administer 0.9% sodium chloride 1,200 ml. IV to infuse over 8 hr. 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.)
Full Explanation
To calculate the IV pump rate, you need to divide the total volume (1,200 ml) by the total infusion time (8 hours). Here's the calculation:
IV Pump Rate (ml/hr) = Total Volume (ml) / Total Infusion Time (hr)
IV Pump Rate (ml/hr) = 1,200 ml / 8 hr
IV Pump Rate (ml/hr) = 150 ml/hr
So, the nurse should set the IV pump to deliver 150 ml/hr.
