A nurse is preparing to administer amikacin 5 mg/kg IM to a client who weighs 110 lb. Available is amikacin injection 250 mg/mL. How many mL should the nurse administer?

(Round the answer to the nearest whole number. Use a leading zero if applicable. Do not use a trailing zero.).

Answer and Explanation

The Correct Answer is ["1"]

To solve this problem, we first need to convert the client’s weight from pounds to kilograms. Then, we can calculate the total amount of amikacin needed. Finally, we can find out how many milliliters of amikacin injection the nurse should administer.

Convert the client’s weight to kilograms: Given that 1 kg = 2.2 lbs, we can calculate the client’s weight in kilograms as follows:

Weight in kg=Weight in lbsConversion factor=110 lbs2.2 lbs/kg≈50 kgWeight in kg=Conversion factorWeight in lbs=2.2 lbs/kg110 lbs≈50 kg

Calculate the total amount of amikacin needed: The doctor ordered 5 mg of amikacin per kg of body weight, so the total amount of amikacin needed is:

Total amikacin=Dose per kg×Weight in kg=5 mg/kg×50 kg=250 mgTotal amikacin=Dose per kg×Weight in kg=5 mg/kg×50 kg=250 mg

Find out how many milliliters of amikacin injection the nurse should administer: Given that the available amikacin injection is 250 mg/mL, we can calculate the volume of injection needed as follows:

Volume of injection=Total amikacinConcentration of injection=250 mg250 mg/mL=1 mLVolume of injection=Concentration of injectionTotal amikacin=250 mg/mL250 mg=1 mL

So, the nurse should administer 1 mL of amikacin injection.

Correct Answer is C

Explanation

Choice A rationale:

While it’s important for the provider to be informed if the medication isn’t working, it’s premature to change the medication after only 6 days.

Amitriptyline does not need to be taken on an empty stomach to be effective.

Choice C rationale:

Amitriptyline, a tricyclic antidepressant, often takes several weeks before a therapeutic effect is felt.

Choice D rationale:

Increasing the dose prematurely can lead to unnecessary side effects. It’s better to wait for the medication to take effect.
