A client is admitted to the intensive care unit recovering from a severe gastrointestinal hemorrhage. The client has a double-lumen peripherally inserted central catheter (PICC). Lumen one is dedicated to a continuous infusion of total parenteral nutrition (TPN). Lumen two is infusing a continuous IV drip of pantoprazole. The client suddenly reports severe dizziness. The cardiac monitor displays sinus bradycardia at 32 beats/min, and the client's blood pressure drops to 76/40 mmHg. The healthcare provider orders atropine 1 mg IV push STAT. The client does not have a patent peripheral IV line. Which of the following is the most appropriate nursing action to administer the medication?

  1. Pause the pantoprazole infusion, flush the lumen with 10 mL of 0.9% sodium chloride, administer the atropine, flush again with 10 mL of 0.9% sodium chloride, and resume the pantoprazole.Cevap
  2. B
    Administer the atropine directly into the Y-site port of the pantoprazole tubing closest to the client without pausing the pump, followed by a normal saline flush.
  3. C
    Pause the TPN infusion, flush that lumen with 0.9% sodium chloride, administer the atropine, flush again, and resume the TPN to avoid altering the gastric pH.
  4. D
    Withhold the atropine and immediately attempt to establish a new large-bore peripheral intravenous access to prevent central line-associated drug precipitation.

Cevap

Pause the pantoprazole infusion, flush the lumen with 10 mL of 0.9% sodium chloride, administer the atropine, flush again with 10 mL of 0.9% sodium chloride, and resume the pantoprazole.
The client is experiencing symptomatic bradycardia, a medical emergency requiring immediate administration of atropine. Since the client only has a double-lumen PICC, the nurse must use one of the existing lumens. The TPN lumen must remain dedicated and cannot be used. The pantoprazole lumen is currently infusing a medication that is highly incompatible with other drugs. To safely administer the atropine without causing precipitation, the nurse must pause the pantoprazole, flush the line thoroughly with normal saline to clear the drug, administer the atropine, flush again, and then resume the continuous infusion. This ensures immediate drug delivery while maintaining IV compatibility.

Adım Adım Çözüm

1
Assess the client's clinical presentation and the urgency of the ordered medication.
The client has symptomatic bradycardia (hypotension, dizziness), which is a medical emergency requiring immediate administration of atropine.
Symptomatic bradycardia can lead to decreased cardiac output and cardiac arrest if not treated promptly.
2
Evaluate the available intravenous access routes.
The client has a double-lumen PICC with TPN infusing in one lumen and pantoprazole infusing in the other. There is no peripheral IV access.
Medications must be administered through a safe, patent line. Establishing new access would cause a dangerous delay in this emergency.
3
Determine the compatibility and dedicated line rules for the existing infusions.
TPN requires a strictly dedicated line and cannot be used for IV push medications. Pantoprazole is chemically incompatible with most medications and must not be mixed at the Y-site.
Using the TPN line risks severe infection and emulsion instability. Mixing atropine with pantoprazole risks chemical precipitation.
4
Select the safest method for medication administration using the available access.
The pantoprazole line must be temporarily paused, flushed with normal saline to clear the line of the incompatible drug, used to push the atropine, flushed again to clear the atropine, and then the pantoprazole infusion is resumed.
This 'flush-administer-flush' method prevents drug precipitation in the tubing while allowing immediate administration of the life-saving medication.

Anahtar Kavram

When administering an IV push medication through a line infusing an incompatible continuous medication (excluding dedicated lines like TPN), the nurse must pause the infusion, flush with normal saline, administer the drug, flush again, and resume the infusion.
