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.

  1. 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

  1. 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

  1. 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:

Hanging the antibiotic medication bag above the level of the primary infusion is an important step in administering an antibiotic via intermittent IV bolus. However, it is not the first step. The medication bag is usually hung higher to allow the antibiotic to infuse by gravity once it’s connected.

Choice B rationale:

Wiping the connection port of the primary IV tubing with an antiseptic swab is a crucial step in preventing infection. However, this is typically done just before connecting the secondary line, not as the first step.

Choice C rationale:

Checking the IV site for signs of infiltration is indeed the first step. It’s important to ensure that the IV catheter is still properly placed in the vein and that there are no signs of infection or infiltration, which could cause complications.

Choice D rationale:

Connecting the tubing of the medication bag to the primary tubing is done after cleaning the port and before hanging the bag. It’s not the first step.

Correct Answer is B

Explanation

Choice A rationale:

While a tuberculin syringe can be used for insulin administration, it’s not necessary when mixing NPH and regular insulin. Insulin syringes are typically used for this purpose.

Choice B rationale:

Injecting air into each vial before withdrawing insulin helps equalize pressure and makes it easier to draw up the insulin. This should be done before withdrawing any insulin.

Choice C rationale:

Withdrawing NPH insulin first contradicts the standard practice of drawing up insulins. The usual recommendation is to draw up short-acting (regular) insulin before intermediate-acting (NPH) insulin.

Choice D rationale:

Shaking the regular insulin vial is unnecessary and could potentially create bubbles, making it harder to draw up the correct dose of insulin.
