When preparing medication from a vial for a subcutaneous injection for a client, which of the following actions should the nurse take?
Hold the syringe so that bubbles collect at the level of the plunger.
Hold the vial with the top facing upward while injecting air into the vial.
Inject air into the vial with the eye of the needle immersed in the fluid.
Hold the syringe at a 45° angle to verify dosage.
The Correct Answer is B
When preparing medication from a vial for subcutaneous injection for a client, the nurse should hold the vial with the top facing upward while injecting air into the vial.
This is because injecting air into the vial equalizes the pressure inside and makes it easier to withdraw the medication 1.
Choice A is wrong because holding the syringe so that bubbles collect at the level of the plunger is not necessary when preparing medication from a vial.
Choice C is wrong because injecting air into the vial with the eye of the needle immersed in the fluid can contaminate the medication.
Choice D is wrong because holding the syringe at a 45° angle is not necessary when verifying dosage.

Correct Answer is C
Explanation
The correct answer is choicec. “You will need to wear a mask when outside of your room.”
Choice A rationale:
Visitors wearing protective gowns is important to prevent infection, but it is not the primary teaching point for the patient themselves.
Choice B rationale:
Patients undergoing allogeneic stem cell transplants are typically placed in private rooms to minimize the risk of infection, not semi-private rooms.
Choice C rationale:
Wearing a mask when outside the room is crucial for the patient to protect themselves from infections due to their compromised immune system during the transplant process.
Choice D rationale:
Negative-airflow rooms are used to prevent the spread of airborne infections from the patient to others, not necessarily to keep the air cleaner for the patient.
Correct Answer is D
Explanation
The nurse should place the extremity in a dependent position before inserting an IV catheter.
This helps to dilate the veins and make them more visible and easier to access.
Choice A is wrong because the nurse should choose a site that is distal to the most proximal site on the extremity selected.
This helps to preserve more proximal sites for future use if needed.
Choice B is wrong because applying a cool compress before insertion of an IV catheter can cause vasoconstriction and make it more difficult to access the vein.
Instead, a warm compress can be applied to help dilate the veins.
Choice C is wrong because the tourniquet should be placed above, not below, the proposed insertion site to help dilate the vein and make it easier to access.
