A nurse is caring for a client who has an implanted venous access port.
Which of the following should the nurse use to access the port?
butterfly needle
An angiocatheter
A 25-gauge needle
A noncoring needle
The Correct Answer is D
The correct answer is choice D, a noncoring needle.
A noncoring needle is a special type of needle that has a beveled tip and a side hole. It is designed to prevent damage to the port’s septum, which is the soft silicone top that serves as the vein access point.
A noncoring needle also reduces the risk of infection and clotting.
Choice A is wrong because a butterfly needle is a small, winged needle that is used for peripheral venous access, not for accessing a port. A butterfly needle can damage the port’s septum and cause leakage or infection.
Choice B is wrong because an angiocatheter is a thin, plastic tube that is inserted into a vein using a needle.
It is used for short-term IV therapy, not for accessing a port. An angiocatheter can also damage the port’s septum and cause complications.
Choice C is wrong because a 25-gauge needle is too small to access a port.
A 25-gauge needle is typically used for subcutaneous injections, not for intravenous injections. A 25-gauge needle can also clog the port or cause hemolysis (breakdown of red blood cells).
Normal ranges for ports vary depending on the type and size of the port, but generally they have a reservoir diameter of 1.5 to 2.5 cm, a catheter length of 40 to 60 cm, and a catheter diameter of 0.8 to 1.2 mm. Ports are usually flushed with saline or heparin solution every 4 to 6 weeks when not in use to prevent clotting.

Correct Answer is C
Explanation
The correct answer is choiceC. Remove the cap and place it sterile-side up on a clean surface.
Choice A rationale:
Placing sterile gauze over areas of spilled solution within the sterile field is not recommended. Spilled solution can compromise the sterility of the field, and covering it with gauze does not restore sterility. Instead, the nurse should avoid spilling solution to maintain the sterile field.
Choice B rationale:
Holding the irrigation solution bottle with the label facing away from the palm of the hand is incorrect. The correct technique is to hold the bottle with the label facing the palm. This prevents the label from getting wet and unreadable, ensuring that the nurse can always identify the solution correctly.
Choice C rationale:
Removing the cap and placing it sterile-side up on a clean surface is the correct action. This maintains the sterility of the cap, preventing contamination when it is replaced on the bottle. Ensuring the cap remains sterile is crucial for maintaining the sterility of the solution.
Choice D rationale:
Holding the bottle in the center of the sterile field when pouring the solution is incorrect. The bottle should be held outside the sterile field to prevent contamination. The solution should be poured carefully to avoid splashing and compromising the sterile field.
Correct Answer is A
Explanation
This is because glass ampules can leave small shards of glass in the solution, which can be harmful if injected into the client. A filter needle has a small mesh that traps any glass particles and prevents them from entering the syringe.
Choice B is wrong because the nurse should break the neck of the ampule away from their body to avoid injury from the glass.
Choice C is wrong because the nurse should use a different needle to inject the client after withdrawing the medication with a filter needle. This is to prevent contamination and reduce pain for the client.
Choice D is wrong because the nurse should dispose of the ampule in a sharps container, not in the trash can. This is to prevent injury and infection from the broken glass.
