If the nurse needs to administer a 2 mL injection what size syringe is most appropriate to use?
5 mL
1 mL
10 mL
3 Ml
The Correct Answer is A
A. A 5 mL syringe can hold up to 5 mL of fluid. It is suitable for administering 2 mL of medication, as it provides enough capacity with some additional space to ensure accurate measurement and prevent overfilling.
B. A 1 mL syringe is too small for administering a 2 mL injection. It would not accommodate the entire volume, and attempting to draw and administer 2 mL with a 1 mL syringe could result in spillage or inaccurate dosing.
C. A 10 mL syringe is larger than necessary for administering a 2 mL injection. While it can hold the required volume and more, it is bulkier and might be less convenient for administering smaller volumes like 2 mL.
D. A 3 mL syringe can also accommodate a 2 mL injection. However, a 5 mL syringe would provide a more appropriate capacity with a bit of extra space, which can be beneficial for accurate measurement and ease of administration.

Correct Answer is D
Explanation
A. A filter needle is used when withdrawing medication from an ampule, but it is not used to administer the injection. After withdrawal, the filter needle should be replaced with a regular IM needle for administration.
B. The ampule should be broken by snapping the neck away from the body, not by bending it to the side, to prevent injury.
C. The nurse should gently tap the top of the ampule, not the bottom, to move the solution downward before opening.
D. The correct technique is to insert the needle into the center of the ampule to withdraw medication, ensuring that the bevel remains below the fluid line to avoid drawing up air.
Correct Answer is D
Explanation
D. Holding the skin taut helps stabilize the area and ensures that the needle penetrates the skin smoothly and at the correct angle. This also helps prevent the needle from going too deep or slipping out of the site during injection.
A. The syringe should be held at a 5 to 15-degree angle to the client's skin, not 20 degrees.
B. For a tuberculin skin test (PPD test), typically 0.1 mL (one-tenth of a milliliter) of PPD is injected intradermally. This is a very small amount compared to 0.5 mL.
C. The length of the needle for an intradermal injection is typically shorter than 1 inch, usually around 3/8 to 5/8 inches (10-16 mm). Using a longer needle may increase the risk of inserting the needle too deeply, potentially leading to subcutaneous rather than intradermal injection.
