A nurse is caring for a client who has a new prescription for sotalol 320 mg/day in two divided doses. The amount available is 80 mg tablets. How many tablets should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Full Explanation
To determine how many tablets of sotalol the nurse should administer with each dose, you can use the following calculation:
Total daily dose / Number of doses per day = Dose per administration
In this case, the total daily dose is 320 mg, and it's divided into two doses per day.
320 mg / 2 doses = 160 mg per administration
Now, you know that the nurse should administer 160 mg of sotalol with each dose. The available tablets are 80 mg each, so you can calculate how many tablets are needed:
Dose per administration / Tablet strength = Number of tablets
160 mg / 80 mg/tablet = 2 tablets
Therefore, the nurse should administer 2 tablets of sotalol with each dose.

A nurse is preparing to administer morphine 0.1 mg/kg IM to a client who weighs 99 lb. Available is morphine 2 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 amount of morphine (in mL) the nurse should administer, follow these steps:
Step 1: Convert the client's weight from pounds to kilograms. 99 lb / 2.2 lb/kg ≈ 45 kg (rounded to the nearest whole number)
Step 2: Calculate the total dose based on the client's weight. 0.1 mg/kg * 45 kg = 4.5 mg
Step 3: Determine how many mL of the available morphine solution (2 mg/mL) are needed to achieve the prescribed dose. 4.5 mg ÷ 2 mg/mL = 2.25 mL
Rounded to the nearest tenth, the nurse should administer 2.3 mL of morphine.
A nurse is preparing to administer dextrose 5% in water 1,000 mL IV to infuse over 6 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 infusion rate in mL/hr for dextrose 5% in water 1,000 mL over 6 hours, you can use the following formula:
Infusion Rate (mL/hr) = Total Volume (mL) / Total Time (hr)
Infusion Rate = 1,000 mL / 6 hr ≈ 166.67 mL/hr
Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 167 mL/hr.
A nurse is preparing to administer acetaminophen 650 mg PO to a client for pain. Available is acetaminophen liquid 160 mg/5 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 amount of acetaminophen liquid to administer, you can use the following formula:
Amount (mL) = (Desired Dose in mg) / (Concentration in mg/mL)
Amount (mL) = 650 mg / (160 mg/5 mL) = 20.31 mL
Rounded to the nearest tenth, the nurse should administer approximately 20.3 mL of acetaminophen liquid.
