A patient suffering from GIT bleeding and his INR value increased. What is the appropriate action?

Appeared in: AIIMS Delhi NO - 2017

Explanation

An increased INR indicates a deficiency in the vitamin K-dependent clotting factors (II, VII, IX, X), leading to impaired hemostasis.
The patient has active GIT bleeding, which is life-threatening when combined with a high INR.
Vitamin K is the direct antidote for warfarin-induced coagulopathy and works by enabling the liver to synthesize functional clotting factors.
Administering Vitamin K is the most appropriate and direct intervention to correct the underlying cause of the bleeding risk.

Option B: Antibiotics are used to treat bacterial infections. They have no direct effect on the blood's clotting cascade or INR levels.
Option C: Hypertonic IV fluids pull fluid from the cells into the vascular space and are used for specific conditions like cerebral edema or severe hyponatremia. They are not the fluid of choice for hemorrhagic shock.
Option D: This option is incorrect because administering antibiotics and hypertonic fluids are not appropriate actions for this clinical scenario.

Clinical Relevance

Nursing practice connection: Use the key finding related to Management of coagulopathy in a patient with active bleeding to guide bedside assessment, documentation, and the next nursing action.
Nurses must be able to recognize the critical nature of an elevated INR in a patient with active bleeding.
Prompt administration of the correct reversal agent (Vitamin K for warfarin) is a key patient safety intervention.
It is crucial to monitor for signs of bleeding (e.g., changes in vital signs, visible bleeding, altered mental status) and to hold anticoagulants as ordered.

How to Approach the Question

First, identify the two critical pieces of information in the stem: the patient has active 'GIT bleeding' and an 'increased INR value'.
Understand the implication of each piece. GIT bleeding is a serious hemorrhage. Increased INR means the blood's ability to clot is impaired.
The question asks for the 'appropriate action'. This requires you to address the root cause of the problem, which is the coagulopathy exacerbating the bleed.
Evaluate each option's mechanism of action. Does it help the blood to clot?
Option A, Vitamin K, is a known precursor for clotting factors and is the specific antidote for warfarin-induced high INR.
Option B, antibiotics, treats infection, which is not the stated problem.

Concept Tested & Keywords

Concept Tested: Management of coagulopathy in a patient with active bleeding.
Stem keywords: GIT bleeding, INR value increased
Lead-in keywords: appropriate action
Clinical cues: The combination of active bleeding (GIT bleeding) and a laboratory value indicating impaired clotting (increased INR) points to a medical emergency requiring correction of the coagulopathy.
