Difficulty: Very hardPharmacological and Parenteral Therapies

A client with septic shock is receiving a continuous intravenous (IV) infusion of norepinephrine via a single-lumen peripherally inserted central catheter (PICC). The client's blood pressure is 88/54 mmHg88/54 \text{ mmHg} and the mean arterial pressure (MAP) is 65 mmHg65 \text{ mmHg}. The healthcare provider prescribes a stat dose of IV pantoprazole and a continuous IV infusion of regular insulin. The nurse is unable to establish additional peripheral IV access due to severe generalized edema. Which of the following actions should the nurse take? (Select all that apply.)

  1. Initiate the continuous regular insulin infusion by connecting it to the Y-site of the primary norepinephrine infusion tubing.Answer
  2. B
    Pause the norepinephrine infusion, flush the PICC with 0.9%0.9\% sodium chloride, administer the IV pantoprazole, and immediately resume the norepinephrine.
  3. C
    Administer the stat dose of IV pantoprazole by connecting the syringe directly to a Y-site on the continuous norepinephrine infusion tubing.
  4. Contact the healthcare provider to urgently request the placement of a multi-lumen central venous catheter or intraosseous access.Answer
  5. Prioritize the continuous norepinephrine infusion and delay the IV pantoprazole administration until a secondary access line is obtained.Answer
  6. F
    Calculate the required continuous insulin dosage by multiplying the prescribed weight-based dose by the client's body weight in pounds.

Answer

The correct actions are to initiate the insulin at the Y-site, request a multi-lumen catheter, and delay the pantoprazole until new access is obtained.
The correct actions prioritize the client's immediate survival (maintaining a MAP of 65 mmHg65 \text{ mmHg}) by never interrupting the norepinephrine infusion. Because regular insulin is compatible with norepinephrine, it can be safely connected to the Y-site. Because pantoprazole is highly incompatible with norepinephrine, it cannot be given through the same line. A new multi-lumen central line or intraosseous access must be requested, and the pantoprazole must be delayed until this safe access is established.

Step-by-Step Solution

1
Analyze the client's hemodynamic status.
The client is borderline stable with a MAP of 65 mmHg65 \text{ mmHg} solely dependent on a continuous norepinephrine infusion.
Determines the absolute priority of maintaining the vasopressor over all other interventions.
2
Determine medication compatibility for the prescribed drugs.
Regular insulin is compatible with norepinephrine, but pantoprazole is highly incompatible with norepinephrine.
Identifies which medications can be safely administered through the existing single-lumen PICC.
3
Formulate a safe administration plan.
The nurse can Y-site the insulin but must establish new access for the pantoprazole without interrupting the pressor.
Ensures timely medication administration while preventing life-threatening hypotension or IV line precipitation.

Key Concept

Management of high-alert continuous IV infusions, Y-site compatibility, and prioritization of hemodynamic stability in critically ill clients.
