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
Enoxaparin is a blood thinner that helps prevent the formation of blood clots in people who have certain medical conditions or who are undergoing certain procedures. Enoxaparin can increase the risk of bleeding, especially if taken with other medications that affect blood clotting, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or aspirin.
Therefore, the nurse should instruct the client to avoid taking pain relievers such as naproxen sodium (choice A), ibuprofen (choice B), or aspirin (choice D) while on enoxaparin. These pain relievers can make the client more likely to bleed when on enoxaparin. Acetaminophen (choice C) is a pain reliever that does not affect blood clotting and can be taken safely with enoxaparin. However, the client should follow the directions on the box to make sure they do not take more than the recommended amount of acetaminophen, as it can cause liver damage in high doses.
Correct Answer is A
Explanation
The correct answer is choice A: “We can review some information to help you select a safe alternative practitioner.” This statement shows respect for the client’s interest in alternative therapies and offers guidance on how to choose a reliable and qualified provider. Alternative therapies can provide some benefits for people with rheumatoid arthritis, such as reducing pain, inflammation, and stiffness, but they should be used as a complement to conventional treatments and not as a substitute.
Choice B is wrong because it implies that the client has no role in deciding their own treatment plan and that alternative therapies are not worth considering.
This may discourage the client from sharing their preferences and concerns with the provider.
Choice C is wrong because it suggests that online support groups are a reliable source of information about alternative remedies, which may not be true.
Online sources may contain inaccurate, misleading, or harmful information that could jeopardize the client’s health and safety.
Choice D is wrong because it encourages the client to try any therapy that fits their personal belief system, without considering the evidence, effectiveness, or potential risks of such therapies. Some alternative therapies may interact with medications, cause side effects, or worsen the condition.
Normal ranges for rheumatoid arthritis are not applicable in this question, as it is not asking about laboratory values or disease activity measures. However, some common tests used to diagnose and monitor rheumatoid arthritis include erythrocyte sedimentation rate (ESR), Creactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies, and joint ultrasound or X-ray.
The normal ranges for these tests may vary depending on the laboratory and the method used.
