A nurse is preparing to administer nalaxone 0.4 mg IV bolus to a client who is experiencing opioid toxicity. Available is naloxone injection 1 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it apples. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.4"]

Identify the Desired Dose and Available Concentration:

Desired Dose: 0.4 mg of naloxone

Available Concentration: 1 mg/mL (This means there is 1 mg of naloxone in every 1 mL of solution)

Set up the Calculation:

We need to find the volume (in mL) that contains the desired dose of 0.4 mg.

We can use the following formula:

Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)

Plug in the Values and Calculate:

Volume (mL) = 0.4 mg / 1 mg/mL

Volume (mL) = 0.4 mL

Round to the Nearest Tenth (if necessary):

0.4 mL

Correct Answer is ["38"]

Explanation

Identify the Given Information:

Infusion Rate: 150 mL/hr

Drop Factor: 15 gtt/mL

Convert the Infusion Rate to mL/min:

There are 60 minutes in 1 hour.

Infusion Rate (mL/min) = 150 mL/hr / 60 min/hr

Infusion Rate (mL/min) = 2.5 mL/min

Calculate the Drip Rate (gtt/min):

Drip Rate (gtt/min) = Infusion Rate (mL/min) x Drop Factor (gtt/mL)

Drip Rate (gtt/min) = 2.5 mL/min x 15 gtt/mL

Drip Rate (gtt/min) = 37.5 gtt/min

Round to the Nearest Whole Number:

38 gtt/min

Correct Answer is ["0.25"]

Explanation

Order: Filgrastim 250 mcg (micrograms)

Desired Unit: mg (milligrams)

Step 1: Conversion Factor

We need to know the relationship between micrograms (mcg) and milligrams (mg).

1 mg = 1000 mcg

Step 2: Set Up the Conversion

We want to convert 250 mcg to mg. To do this, we'll divide the given dose (250 mcg) by the conversion factor (1000 mcg/mg):

250 mcg x (1 mg / 1000 mcg)

Step 3: Perform the Calculation

Multiply the numerators: 250 x 1 = 250

Multiply the denominators: 1 x 1000 = 1000

Divide the result: 250 / 1000 = 0.25

Step 4: Answer with Correct Units and Rounding

The result is 0.25 mg.

The problem asks us to round to the nearest hundredth, which we already have (0.25).

The problem also states to use a leading zero if it applies (which it does) and not use a

trailing zero (which we don't have).

Answer: 0.25 mg
