An adult client is admitted with a severe systemic fungal infection and has a single peripheral intravenous (IV) catheter. The client is currently receiving a continuous hydration infusion of 0.9% sodium chloride at 100 mL/hr. The healthcare provider prescribes a scheduled intravenous dose of amphotericin B. Which action must the nurse take to administer this medication safely?

  1. A
    Pause the continuous fluid, infuse the medication directly, and immediately resume the hydration fluid.
  2. B
    Connect the medication tubing to the primary Y-site to allow concurrent infusion.
  3. Flush the IV line with 5% dextrose in water (D5W) before and after the medication infusion.Cevap
  4. D
    Flush the IV line with 0.9% sodium chloride before and after the medication infusion.

Cevap

The nurse must flush the intravenous line with 5% dextrose in water (D5W) before and after administering the medication.
Amphotericin B is incompatible with 0.9% sodium chloride and will form a precipitate if the two mix. To ensure safe administration through a single lumen, the nurse must clear the tubing of all saline by flushing it with 5% dextrose in water (D5W)—which is chemically compatible with the medication—both before and after the infusion.

Adım Adım Çözüm

1
Identify the primary continuous infusion fluid.
The client is receiving 0.9% sodium chloride.
Understanding the current intravenous environment is critical before introducing any new pharmacological agents.
2
Determine the compatibility of the prescribed medication with the primary fluid.
Amphotericin B is strictly incompatible with 0.9% sodium chloride and all other electrolyte-containing solutions.
Mixing incompatible fluids leads to chemical reactions, such as precipitation, which can cause an embolism or catheter occlusion.
3
Select the appropriate intervention to ensure safe administration through a single lumen.
The nurse must flush the line with 5% dextrose in water (D5W) to clear the saline prior to and following the medication infusion.
D5W is compatible with amphotericin B and safely separates the medication from the saline.
