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.)

Answer and Explanation

The Correct Answer is ["2.3"]

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.

Correct Answer is ["10"]

Explanation

To calculate the volume in milliliters (mL) of amoxicillin oral suspension needed to administer 775 mg, you can use the following formula:

Volume (mL) = (Desired dose in mg / Concentration in mg/mL)

Given:

Desired dose = 775 mg
Concentration = 400 mg/5 mL

First, calculate the concentration in mg/mL by dividing 400 mg by 5 mL:

Concentration = 400 mg / 5 mL = 80 mg/mL

Now, use the formula to calculate the volume in mL:

Volume (mL) = (775 mg / 80 mg/mL)

Volume (mL) ≈ 9.69 mL

Rounded to the nearest whole number, the nurse should administer approximately 10 mL of amoxicillin oral suspension to provide a dose of 775 mg.

Correct Answer is ["150"]

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.
