A nurse is preparing to administer duloxetine 120 mg PO once daily to a client. Available is duloxetine 40 mg capsules. How many capsules 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
If each capsule contains 40 mg of duloxetine, then we need to calculate how many capsules are required to
make up the daily dose of 120 mg:
120 mg ÷ 40 mg/capsule = 3 capsules
Therefore, the nurse should administer 3 capsules of duloxetine per dose.

A nurse is preparing to administer vancomycin 500 mg via intermitent IV bolus to a client. Available is vancomycin powder for injection 1 g vial. The nurse reconstitutes the powder for a final concentration of vancomycin 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.)
Full Explanation
First, we need to determine how many milligrams of vancomycin are in each milliliter of the reconstituted solution:
1 g = 1,000 mg
If we reconstitute 1 g of vancomycin powder for injection in enough diluent to make a final volume of 200 mL, the concentration will be:
1,000 mg ÷ 200 mL = 5 mg/mL
Now, we can calculate how many milliliters of the reconstituted solution the nurse should administer to deliver 500 mg of vancomycin:
500 mg ÷ 5 mg/mL = 100 mL
Therefore, the nurse should administer 100 mL of the reconstituted vancomycin solution via intermitent IV
bolus.
A nurse is preparing to administer isoniazid 187 mg IM. Available is isoniazid injection 100 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.)
Full Explanation
To calculate the number of mL the nurse should administer, you need to divide the dose of isoniazid (187 mg) by the concentration of the isoniazid injection (100 mg/mL). This gives you 187 mg / (100 mg/mL) =
1.87 mL. When rounded to the nearest tenth, this becomes 1.9 mL. So, the nurse should administer 1.9 mL of isoniazid injection.
A nurse is preparing to administer gentamicin 1 mg/kg IM to a client who weighs 154 lb. Available is gentamicin solution 40 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.)
Full Explanation
Step 1: Convert pounds to kilograms.
154 lb * (1 kg / 2.20462 lb) = 70 kg
Step 2: Calculate the total dose of gentamicin.
1 mg/kg * 70 kg = 70 mg
Step 3: Calculate the volume of gentamicin solution to administer.
70 mg / 40 mg/mL = 1.75 mL
Therefore, the nurse should administer 1.8 mL of gentamicin solution.
