A nurse is assessing a client who received hydromorphone 4 mg IV 15 min ago.
The client has a respiratory rate of 10/min.
The nurse should prepare to administer which of the following medications? .

The correct answer is D.

Choice A reason: “A. Using this machine increases my risk of overdose.” This statement is incorrect because PCA pumps are designed with safety mechanisms to prevent overdose. The pump is programmed to deliver a specific dose of medication at set intervals, and it will not dispense more medication than what is prescribed by the healthcare provider.

Choice B reason: “B. I can get pain medication any time as long as I press the button.” While it is true that the patient can self-administer medication, PCA pumps have a lockout interval that prevents the machine from delivering another dose until a certain amount of time has passed, ensuring that the patient cannot receive medication too frequently.

Choice C reason: “C. My partner can press my pain medication button for me if I am sleeping.” This statement is incorrect. Only the patient should press the button on the PCA pump to ensure that the medication is administered safely and according to the patient’s current level of pain. Allowing someone else to press the button could lead to unsafe dosing.

Choice D reason: “D. I will receive a limited amount of pain medication when I press the button.” This is the correct statement. The PCA pump allows the patient to administer a controlled amount of pain medication within safe limits set by the healthcare provider. The pump is programmed to deliver a specific dose of medication, and there is a limit to the number of doses that can be administered per hour.

Choice A rationale:

An angiocatheter is not appropriate for accessing an implanted venous access port. Angiocatheters are large-bore catheters designed for rapid fluid administration and are typically used for peripheral venous access. They are not suitable for accessing the small, specialized ports used for central venous access.

Choice B rationale:

A 25-gauge needle is too small for accessing an implanted venous access port. While smaller gauge needles are suitable for delicate procedures and patients with fragile veins, they might not provide adequate flow for certain therapies or blood draws. Accessing a port with a needle that is too small can lead to increased pressure, potentially damaging the port or causing discomfort to the patient.

Choice C rationale:

A butterfly needle is also not the best choice for accessing an implanted venous access port. Butterfly needles, also known as winged infusion sets, are commonly used for short-term peripheral venous access. They are not designed for accessing implanted ports, which require a noncoring needle for precise and safe access without damaging the port membrane.

Choice D rationale:

(Correct Choice) A noncoring needle, also known as a Huber needle, is the correct choice for accessing an implanted venous access port. Noncoring needles have a specially designed tip that creates a smaller puncture hole, reducing damage to the port membrane and minimizing patient discomfort. They are specifically designed for accessing ports and are the standard choice for this procedure.
