Heparin is an anticoagulant that helps prevent further clot formation. It is titrated based on a partial thromboplastin time (PTT). The therapeutic PTT target is 1.5-2.0 times the normal reference range of 25-35 seconds. A PTT value >100 seconds would be considered critical and could result in life-threatening side effects. Common sentinel events that result from heparin drips include epistaxis, hematuria, and gastrointestinal bleeds.
(Option 1) A normal hematocrit for a female is 35%-47% (0.35-0.47). In a client with a history of chronic anemia, a hematocrit of 30% (0.30) may be an expected finding.
(Option 3) A normal platelet count is 150,000-400,000/mm³ (150-400 x 109/L). In a client with a history of liver cirrhosis, a platelet count of 80,000/mm³ (80 x 109/L) would be anticipated. An episode of bleeding rarely occurs with a platelet count >50,000 mm³ (50 x 109/L).
(Option 4) A normal prothrombin time is 11-16 seconds, and so a level of 11 seconds would not be concerning.
