A nurse is preparing to administer midazolam 0.2 mg/kg via IV bolus now. The client weighs 220 lb. How many mg 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.)

Answer and Explanation

The Correct Answer is ["20"]

To calculate the dose of midazolam to administer, we need to convert the client's weight from pounds to kilograms, and then multiply by the dose per kilogram.

Given: Client weight = 220 lb

Dose of midazolam = 0.2 mg/kg

First, let's convert the client's weight from pounds to kilograms:

1 lb ≈ 0.453592 kg (approximately 0.45 kg, for simplicity)

Client weight in kilograms ≈ 220 lb × 0.45 kg/lb ≈ 99 kg

Now, let's calculate the dose of midazolam:

Dose = Weight (in kg) × Dose per kg Dose ≈ 99 kg × 0.2 mg/kg = 19.8 mg

Rounded to the nearest whole number, the nurse should administer approximately 20 mg of midazolam.

Correct Answer is A

Explanation

Alprazolam is a benzodiazepine medication commonly used to treat anxiety and insomnia. Here's the rationale for each option:

A. "Avoid activities that require alertness, such as driving.": Alprazolam can cause drowsiness and impair cognitive function, so it's essential for clients to avoid activities that require alertness, such as driving or operating heavy machinery, while taking this medication. Providing this instruction promotes safety and prevents accidents.

B. "Monitor for peripheral edema.": Peripheral edema is not a common side effect of alprazolam. This instruction is not relevant to the use of this medication.

C. "Take this medication with a high-fat meal.": Alprazolam can be taken with or without food, but taking it with a high-fat meal may delay its absorption. Therefore, it is not necessary to instruct the client to take it with a high-fat meal, especially since this may affect the medication's effectiveness.

D. "Take this medication every night before sleep.": While alprazolam may be used to treat insomnia, it is not typically recommended for nightly use due to the risk of dependence and tolerance. Using it nightly can lead to addiction and withdrawal symptoms if abruptly stopped. Therefore, this instruction is not appropriate.

Correct Answer is ["0.25"]

Explanation

To calculate the volume of haloperidol solution needed, we can use the formula:

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

Given: Dose of haloperidol = 5 mg

Concentration of haloperidol solution = 20 mg/mL

Substituting the given values into the formula:

Volume(mL)=5 mg/20 mg/mL

Volume(mL)=5/20

Volume(mL)=0.25 mL

Rounded to the nearest hundredth, the nurse should administer 0.25 mL of haloperidol solution.
