A nurse is developing a plan of care for a newborn whose mother tested positive for heroin during pregnancy.

The newborn is experiencing neonatal abstinence syndrome.

Which of the following actions should the nurse include in the plan?

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.

Choice A option

Fibrinogen level: Fibrinogen is a protein involved in the blood clotting process, but in this case, it is not appropriate because is not the primary laboratory test used to monitor warfarin therapy. Monitoring fibrinogen levels is more relevant in assessing bleeding disorders or certain medical conditions.

Choice B option

PTT (Partial Thromboplastin Time): PTT is another laboratory test used to evaluate blood clotting function, particularly the intrinsic pathway of the clotting cascade. PTT is not routinely used to monitor warfarin therapy; it is more commonly used to monitor other anticoagulant medications like heparin.

Choice C option

The nurse should plan to report the client's INR (International Normalized Ratio) to obtain a prescription for the client's daily warfarin. INR is a critical laboratory test used to monitor the effectiveness and safety of warfarin therapy.

Warfarin is an anticoagulant medication commonly prescribed to prevent and treat blood clots. It works by interfering with the body's ability to use vitamin K to form blood clots. Monitoring the INR is essential because it indicates how long it takes for the blood to clot, and it helps determine if the client's warfarin dosage needs adjustment to achieve the desired level of anticoagulation.

Choice D option

Platelet count: Platelet count is essential to assess the number of platelets in the blood, which are crucial for normal clotting. However, platelet count monitoring is not the primary focus when prescribing warfarin. It is typically used to evaluate thrombocytopenia (low platelet count) or other conditions affecting platelet function.
