Difficulty: Very hardPharmacological and Parenteral Therapies

A nurse is caring for a hemodynamically unstable client with severe sepsis who has a blood pressure of 82/40 mm Hg. The client is receiving a continuous intravenous (IV) infusion of norepinephrine through the distal port of a newly placed triple-lumen central venous catheter (CVC). The provider prescribes a 500 mL bolus of 0.9% sodium chloride and pantoprazole 40 mg IV push. Which of the following actions represent safe parenteral medication administration and physiological management for this client? (Select all that apply.)

  1. Initiate the 0.9% sodium chloride bolus through a separate peripheral IV or a different central line lumen rather than the one infusing norepinephrine.Answer
  2. B
    Flush the distal lumen infusing norepinephrine with 10 mL of 0.9% sodium chloride before and after the pantoprazole dose to ensure line patency.
  3. C
    Elevate the head of the client's bed to a high-Fowler's position during the fluid bolus to prevent fluid volume overload and pulmonary edema.
  4. Aspirate for a brisk blood return from the selected central venous catheter lumen to confirm patency prior to administering the pantoprazole.Answer
  5. E
    Administer the pantoprazole via rapid IV push over 15 to 30 seconds to quickly achieve therapeutic serum levels and prevent stress ulcers.
  6. Verify the Y-site compatibility of pantoprazole with any other continuous infusions if a shared central line lumen must be utilized.Answer

Answer

The correct actions are: initiating the fluid bolus through a separate line, aspirating for blood return prior to IV push administration, and verifying Y-site compatibility before using a shared lumen.
Safe parenteral therapy in critical care demands that high-risk continuous infusions like norepinephrine remain uninterrupted and un-bolused. Using a separate line for fluid resuscitation prevents speed shock. Verifying blood return ensures the central line is intravascular and safe for use, while checking Y-site compatibility prevents catheter occlusion from drug precipitation.

Step-by-Step Solution

1
Evaluate the implications of the client's hemodynamic status (BP 82/40 mm Hg) on positioning.
Determine that high-Fowler's position is contraindicated because it decreases venous return and exacerbates hypotension.
Maintaining adequate preload is essential in septic shock.
2
Analyze the safety risks of manipulating a central line lumen currently infusing a high-alert vasopressor (norepinephrine).
Identify that flushing or bolusing through this specific lumen is prohibited.
Flushing pushes the residual vasopressor in the catheter rapidly into the bloodstream, causing a dangerous spike in blood pressure.
3
Determine the correct administration protocols for central lines and IV push pantoprazole.
Confirm that aspirating for blood return, verifying compatibility, and pushing the medication slowly (over 2 minutes) are required.
These steps ensure the medication enters the vein safely without precipitating or causing adverse rapid-infusion reactions.

Key Concept

Safe administration of parenteral therapies in critically ill clients requires meticulous line management, strict adherence to infusion rates, verification of compatibility, and physiological considerations such as positioning for shock.
