A nurse is preparing to administer a medication from an ampule. Which of the following is an appropriate action for the nurse to take?
Cleanse the tip of the ampule with an alcohol swab after opening.
Add 0.5 mL of diluent to the medication.
Use a filter needle to aspirate the medication.
Inject air into the ampule prior to drawing the medication into a syringe.
The Correct Answer is C
The correct answer is choice C. Use a filter needle to aspirate the medication.
This is because a filter needle can prevent glass particles from being drawn into the syringe when aspirating medication from an ampule.
Glass particles can cause harm to the patient if injected.
Choice A is wrong because cleansing the tip of the ampule with an alcohol swab after opening is not necessary and may contaminate the medication.
Choice B is wrong because adding 0.5 mL of diluent to the medication may alter the concentration and dosage of the medication.
Choice D is wrong because injecting air into the ampule prior to drawing the medication into a syringe is not required and may create pressure that can cause the ampule to break.

Correct Answer is D
Explanation
The correct answer is choice D. This type of device is useful for a client who cannot assist.
A mechanical lift is used to transfer residents who cannot support their own weight.
It does not require the client to use upper body strength, as choice A suggests.
The lower end of the sling should go under the client’s thighs, not below the calves, as choice B states.
The sides of the sling are not for the client to hold on to, but for the caregiver to attach to the hooks on the lift, as choice C implies.
Therefore, choices A, B and C are wrong because they do not reflect the proper use of a mechanical lift.
