A patient with venous thrombosis is ordered Heparin sulfate 1300 units/hour by continuous intravenous infusion. The pharmacy delivers the following solution: Heparin 25,000 units mixed in 500 ml of D5W. What is the rate (in ml/hr) that the nurse will set the infusion pump to deliver the ordered dose? Calculate and fill in the blank (Round final answer to the nearest whole number).
The Correct Answer is ["26"]
Calculation:
- Identify the prescribed dose and IV concentration
Prescribed Dose: 1,300 units/hr
IV Concentration: 25,000 units in 500 mL
- Calculate the concentration in units per mL
Concentration = 25,000 ÷ 500 = 50 units/mL
- Calculate the infusion rate in mL/hr
Infusion Rate (mL/hr) = Prescribed Dose ÷ Concentration
Infusion Rate = 1,300 ÷ 50
Infusion Rate = 26 mL/hr

Correct Answer is D
Explanation
A. Epigastric discomfort: Epigastric pain is a common symptom of peptic ulcer disease and can usually be managed with medication and lifestyle modifications. While important, it is not immediately life-threatening.
B. Dyspepsia: Dyspepsia, or indigestion, is a chronic symptom associated with ulcer disease. It causes discomfort but does not indicate an acute or emergent complication.
C. Constipation: Constipation may occur due to medications or diet, but it is not directly related to peptic ulcer disease and is not a priority finding.
D. Hematemesis: Vomiting blood indicates active gastrointestinal bleeding, which is a potentially life-threatening complication of peptic ulcer disease. Immediate assessment and intervention are required to prevent shock and further complications, making this the priority finding.
Correct Answer is D
Explanation
A. Activated partial thromboplastin time (aPTT): aPTT is used to monitor unfractionated heparin therapy, not warfarin. It measures the intrinsic and common coagulation pathways and does not reflect the anticoagulant effect of warfarin.
B. Bleeding time: Bleeding time assesses platelet function rather than coagulation factor activity. It is not useful for monitoring warfarin therapy and does not indicate therapeutic anticoagulation.
C. Hemoglobin (Hb): Hemoglobin levels indicate oxygen-carrying capacity and can reflect blood loss, but they do not provide information about anticoagulation status. Monitoring Hb alone is insufficient for warfarin therapy management.
D. Prothrombin time (PT/INR): PT, often expressed as INR, measures the extrinsic coagulation pathway, which is affected by warfarin’s inhibition of vitamin K–dependent clotting factors. Regular monitoring ensures therapeutic anticoagulation while minimizing the risk of bleeding complications.
