Difficulty: EasyPharmacological and Parenteral Therapies

A nurse is caring for a client who was admitted with severe pneumonia and dehydration. The client has a double-lumen central venous catheter, is receiving a continuous infusion of 0.9% sodium chloride, and has new prescriptions for scheduled IV levofloxacin and PRN IV morphine. Which of the following actions by the nurse demonstrate safe parenteral therapy practices? Select all that apply.

  1. Flushing the IV lumen with sterile normal saline before and after administering the PRN IV morphine.Answer
  2. Verifying the Y-site compatibility of levofloxacin with the continuous 0.9% sodium chloride infusion before administration.Answer
  3. C
    Administering the IV morphine directly into the continuous infusion line without verifying compatibility with the primary fluid.
  4. D
    Calculating the levofloxacin infusion rate using only the medication's active volume, excluding the added diluent volume.
  5. E
    Prioritizing the administration of the scheduled IV levofloxacin over assessing the client for a sudden onset of severe respiratory distress.

Answer

The safe practices are flushing the IV lumen with sterile normal saline before and after administering the PRN IV morphine, and verifying the Y-site compatibility of levofloxacin with the continuous 0.9% sodium chloride infusion before administration.
Safe parenteral therapy requires confirming compatibility before mixing any fluids or medications in the same line. Furthermore, flushing a line with a compatible fluid like sterile normal saline before and after an IV push medication ensures the entire dose reaches the client and clears the line of any potential remnants that could react with subsequent infusions.

Step-by-Step Solution

1
Evaluate each action for adherence to safe IV medication administration standards.
Flushing the line and checking compatibility are identified as fundamental safety protocols.
These actions prevent adverse drug interactions, precipitation, and ensure accurate dose delivery.
2
Analyze the action of administering IV morphine without a prior compatibility check.
This action is determined to be highly unsafe.
Mixing incompatible medications can cause physical or chemical incompatibilities, leading to severe patient harm.
3
Review the described method for calculating the levofloxacin infusion rate.
Excluding the diluent volume is identified as a critical calculation error.
The total volume infused (medication plus diluent) must be used to accurately program the IV pump to deliver the correct dose over the prescribed time.
4
Apply prioritization frameworks to the scenario involving a sudden onset of respiratory distress.
Ignoring acute respiratory distress to administer a scheduled medication is recognized as a life-threatening prioritization error.
Airway and breathing emergencies must be addressed immediately before performing routine tasks.

Key Concept

Safe administration of parenteral therapies requires strict adherence to drug compatibility checks, correct total volume calculations, proper line flushing, and prioritizing acute life-threatening changes over routine medication administration.
