A nurse is preparing to reconstitute amoxicillin/clavulanate potassium oral suspension for administration to a client who has a respiratory tract infection. According to the label, which of the following actions should the nurse take? (Refer to the medication label below.)
Directions for mixing
Tap bottle until all powder flows freely. Add approximately 2/3 of total water for reconstitution
Shake vigorously to wet powder. Add remaining water, again shake vigorously Dosage: See accompanying prescribing Information
Discard after 10 days.
125 mg/5 mL
AMOXICILLIN CLAVULANATE POTASSIUM FOR ORAL SUSPENSION
When reconstituted, each 5ml contains AMOXICILLIN 125 mg. as the trihydrate
CLAVULANIC
ACID, 31.25 mg.
as clavulanate potassium
75mL
(when reconstituted)
A. Store the medication at room temperature following reconstitution
Store the medication at room temperature following reconstitution: This option is incorrect. While it provides information about the storage of the medication after reconstitution, it doesn't pertain to the reconstitution process itself. Storage information is essential but not part of the reconstitution process.
B. Use 0.9% sodium chloride solution as a diluent
Use 0.9% sodium chloride solution as a diluent: This option is incorrect. The label instructions mention adding water for reconstitution, not sodium chloride solution. Using the wrong diluent can result in incorrect drug concentrations and potential harm to the patient.
C. Discard any remaining medication after 10 days
Discard any remaining medication after 10 days: This option is correct. The label clearly states that the reconstituted medication should be discarded after 10 days. This is important information for safe medication administration.
D. Roll the vial gently in hands to mix the medication
Roll the vial gently in hands to mix the medication: This option is incorrect. The label instructions specify shaking vigorously to wet the powder and then adding the remaining water, followed by vigorous shaking. Rolling the vial gently is not mentioned in the label instructions.

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.
