A nurse is assessing a child who has bacterial pneumonia.

Which of the following manifestations should the nurse expect?

This is because abruptly stopping TPN can cause hypoglycemia, which is a low blood sugar level that can cause shakiness, diaphoresis, confusion, and seizures. Therefore, infusing dextrose 10% in water temporarily at the same rate as the TPN can prevent this adverse effect. Dextrose 10% in water is a hypertonic solution that contains 340 calories per liter and can maintain the client’s blood glucose level until the new TPN bag arrives.

Choice A is wrong because giving 500 mL of lactated Ringer’s solution would not provide enough calories or glucose to prevent hypoglycemia. Lactated Ringer’s solution is an isotonic solution that contains electrolytes but no calories or glucose.

Choice B is wrong because temporarily discontinuing the infusion would cause hypoglycemia, which can be life-threatening for the client.

Choice C is wrong because slowing the TPN infusion rate would also cause hypoglycemia, as the client would receive less calories and glucose than prescribed.

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.
