A nurse is preparing a medication from a vial for a subcutaneous injection for a client.
Which of the following actions should the nurse perform?
Hold the vial with the top facing upward while injecting air into the vial.
Hold the syringe at a 45° angle to verify dosage.
Hold the syringe so that bubbles collect at the level of the plunger.
Inject air into the vial with the eye of the needle immersed in the fluid.
The Correct Answer is D
Choice A rationale:
the nurse should hold the vial upside down and insert the needle into the center of the rubber stopper.
Choice B rationale:
Holding the syringe at a 45° angle to verify dosage is not a standard practice during the preparation of medication from a vial. The syringe should be held upright at 90° to accurately measure the desired dosage.
Choice C rationale:
Holding the syringe so that bubbles collect at the level of the plunger is incorrect. The nurse should hold the syringe so that bubbles collect at the level of the needle tip. Bubbles should be expelled from the syringe before withdrawing the medication to ensure accurate dosage.
Choice D rationale:
Injecting air into the vial with the eye of the needle immersed in the fluid is correct. This action prevents the formation of bubbles and ensures accurate dosage.

Correct Answer is C
Explanation
Choice A rationale:
Choosing the most proximal site on the extremity is not recommended. Peripheral IV catheters are typically inserted in more distal sites to preserve more proximal sites for other needs.
Choice B rationale:
the nurse should place the extremity in an elevated position, to reduce blood flow and make the veins more visible.
Choice C rationale:
Placing the tourniquet above the proposed insertion site is the correct action. This helps distend the veins, making them more visible and accessible for insertion by occluding venous return thus engorging the vein.
Choice D rationale:
Applying a cool compress is not a standard practice before IV catheter insertion. Warm compresses may be used to enhance vein visibility.
Correct Answer is C
Explanation
Choice A rationale:
this is not enough to prevent clogging and ensure adequate hydration.
Choice B rationale:
Combining medications with the formula in the feeding bag may alter the absorption and effectiveness of the medications.
Choice C rationale:
Diluting crushed medications with sterile water individually ensures accurate dosing and avoids potential interactions.
Choice D rationale:
Mixing medications in a single syringe may cause interactions between medications and compromise accurate dosing while preventing obstruction.
