Zorluk: OrtaPharmacological and Parenteral Therapies

During the management of a client with diabetic ketoacidosis, a continuous intravenous infusion of regular insulin is running via a dedicated peripheral catheter. A new prescription for an intermittent intravenous antibiotic must be initiated promptly. The drug reference manual indicates that this specific antibiotic is physically incompatible with regular insulin. Which intervention ensures safe parenteral administration?

  1. A
    Suspend the insulin infusion temporarily, flush the line thoroughly with normal saline, infuse the antibiotic, and then resume the insulin.
  2. B
    Connect the antibiotic tubing to the port closest to the client's intravenous insertion site.
  3. Initiate a second peripheral venous access site to administer the antibiotic.Cevap
  4. D
    Withhold the antibiotic infusion until the client's blood glucose levels fall within the normal target range.

Cevap

The correct action is to initiate a second peripheral venous access site to administer the antibiotic independently.
When two intravenous medications are physically incompatible, they absolutely cannot be mixed in the same line due to the risk of precipitate formation, which can cause catheter occlusion or life-threatening emboli. Because the client is receiving a continuous regular insulin infusion for diabetic ketoacidosis, pausing the infusion is clinically contraindicated as it would rapidly worsen the client's ketoacidosis. Therefore, the only safe and effective pharmacological action is to establish a second peripheral intravenous line.

Adım Adım Çözüm

1
Analyze the clinical scenario and the pharmacological properties of the prescribed medications.
The client requires continuous insulin for diabetic ketoacidosis and a prompt antibiotic for infection, but the two medications are physically incompatible in the same line.
Identifying physical incompatibility is the first critical step in preventing medication errors and potentially fatal adverse reactions.
2
Determine the clinical feasibility of interrupting the primary continuous infusion.
Regular insulin given for diabetic ketoacidosis has a very short half-life; pausing it can cause severe rebound hyperglycemia and worsening metabolic acidosis.
Continuous high-alert medications for life-threatening, unstable conditions should not be interrupted to accommodate intermittent therapies.
3
Select the safest administration route that adheres to parenteral therapy guidelines.
A new, independent peripheral intravenous site must be established.
Separate venous access ensures both medications are delivered safely and on schedule without the risk of line precipitation or interruption of critical endocrine therapy.
