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.).
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 D
Explanation
Choice A rationale:
While reminding the client to change positions slowly is important to prevent orthostatic hypotension, it is not the priority before administering furosemide.
Choice B rationale:
Preparing the client’s medication is an important step, but it should be done after reviewing the client’s electrolyte levels.
Choice C rationale:
Recording the client’s urinary output is important when administering furosemide, a diuretic, but it is not the priority action.
Choice D rationale:
Reviewing the client’s electrolyte levels is crucial before administering furosemide because it can cause electrolyte imbalances, including low potassium levels, which can lead to serious cardiac complications.
Correct Answer is D
Explanation
Choice A rationale:
Hypotension is not typically a symptom of withdrawal from diazepam. Withdrawal from diazepam, a benzodiazepine, usually results in symptoms opposite to its therapeutic effects.
Choice B rationale:
Drowsiness is not a symptom of withdrawal from diazepam. In fact, insomnia or difficulty sleeping may occur during withdrawal.
Choice C rationale:
Anorexia or loss of appetite may occur during withdrawal from some substances but it’s not typically associated with benzodiazepine withdrawal.
Choice D rationale:
Tremors are a common symptom of withdrawal from diazepam. Other symptoms can include anxiety, restlessness, irritability, and even seizures in severe cases.
