Medical Surgical Peptic ulcers #4

Question

A client recently diagnosed with peptic ulcer disease on warfarin has been prescribed pantoprazole. The nurse contacts the client’s provider with this information and pays close attention to which lab?

Answers

  1. Hct & Hgb
    • Rationale:

      This answer is not correct because H & H (hematocrit and hemoglobin) measures the amount of red blood cells. This is a test used to diagnose anemia.

  2. PT/INR
    • Rationale:

      This answer is correct because using proton pump inhibitors with warfarin can possibly increase the effects of warfarin. Prolonged INR can cause life-threatening bleeding. If any increase in the INR is indicated, warfarin should be adjusted to maintain the desired level of anticoagulation.

  3. PLT
    • Rationale:

      This answer is not correct because PLT (platelets) measures the amount of platelets in the blood. This test is useful for clients on certain medications that can affect the platelet count or to diagnose certain diseases/illnesses.

  4. UA
    • Rationale:

      This answer is not correct because the UA (urinalysis) is used to screen urine. This lab test can detect infections or metabolic diseases.

Overview

Proton pump inhibitors administered with warfarin may potentially increase the effects of the anticoagulant. Contacting the provider with this information, as well as careful monitoring of PT/INR is an important intervention.

Explanation

Learning Outcomes

Proton pump inhibitors administered with warfarin may potentially increase the effects of the anticoagulant. Prolonged INR can cause life-threatening bleeding. Contacting the provider with this information, as well as careful monitoring of PT/INR is an important intervention. If any increase in the INR is indicated, warfarin should be adjusted to maintain the desired level of anticoagulation. H & H measures the amount of red blood cells, making it a good indicator of anemia as a result of bleeding from the stomach in peptic ulcer disease. Platelets are tiny cells that help blood clot and are checked when there is suspicion of a disorder that causes platelet aggregation. The UA is used to screen urine. This lab test can detect infections or metabolic diseases.

Test Taking Tip

Understand lab studies and which meds require which lab studies.
