During a shift assessment, the nurse reviews the electronic health record of a client being treated for a deep vein thrombosis. Unfractionated heparin is currently infusing continuously via a peripheral venous catheter. The provider has newly entered a prescription for ketorolac tromethamine 30 mg IV every 6 hours for reports of severe back pain. Which of the following is the priority nursing action?

  1. Withhold the ketorolac and contact the prescribing provider to recommend a different class of analgesic.Cevap
  2. B
    Administer the ketorolac through a separate peripheral IV insertion site to prevent precipitation.
  3. C
    Verify the client's most recent activated partial thromboplastin time (aPTT) prior to administration.
  4. D
    Calculate a weight-based dosage of the ketorolac to ensure the prescribed amount is within safe limits.

Cevap

Withhold the ketorolac and contact the prescribing provider to recommend a different class of analgesic.
Ketorolac is a potent nonsteroidal anti-inflammatory drug (NSAID) that strongly inhibits platelet aggregation and carries a high risk of gastrointestinal bleeding. Administering any NSAID to a client who is actively receiving a continuous infusion of an anticoagulant, such as unfractionated heparin, creates an unacceptable and severe risk for life-threatening hemorrhage. The nurse's primary responsibility is patient advocacy and safety, which requires withholding the contraindicated medication entirely and collaborating with the provider to find a safe alternative for pain management.

Adım Adım Çözüm

1
Identify the therapeutic classifications and side effect profiles of the prescribed medications.
Heparin is a continuous systemic anticoagulant. Ketorolac is a potent nonsteroidal anti-inflammatory drug (NSAID) that disrupts platelet function and irritates the gastrointestinal mucosa.
Understanding drug classes is essential for identifying dangerous pharmacological interactions before administration.
2
Analyze the physiological outcome of combining these two specific medications in the client.
The combination of systemic anticoagulation (heparin) and platelet inhibition (ketorolac) exponentially increases the client's risk for life-threatening internal hemorrhage, particularly in the gastrointestinal tract.
Nurses must synthesize knowledge of pharmacodynamics to anticipate severe adverse effects.
3
Determine the priority nursing intervention based on the clinical judgment of patient safety.
The nurse must refuse to administer the contraindicated medication and immediately notify the provider to obtain a prescription for a safe alternative, such as acetaminophen or an opioid.
Patient safety and advocacy require the nurse to withhold dangerous prescriptions rather than modifying administration techniques or merely assessing labs.
