A patient is ordered to start an IV continuous Heparin drip. Prior to starting the medication, the nurse would ensure what information is gathered correctly before initiating the drip? Select all that apply: *.
Vital signs
Weight
PT/INR level
EKG
aPTT level.
Correct Answer : B,E
The nurse would need to know the patient’s weight and aPTT level before starting the IV continuous Heparin drip.
Here is why:
• Weight: Heparin dosing is based on the patient’s weight, so the nurse would want to make sure the documented weight of the patient is current and accurate. The initial bolus and infusion rate are calculated using the patient’s weight in kilograms.
• aPTT: Heparin works by enhancing the activation of antithrombin III, which prevents the activation of thrombin and the conversion of fibrinogen to fibrin. Heparin affects the intrinsic pathway of clotting, and its therapeutic effect is monitored by measuring the activated partial thromboplastin time (aPTT). The normal range for aPTT is about 30-40 seconds, and the therapeutic range for Heparin is 1.5-2.5 times the normal value. The nurse would need to check the baseline aPTT before starting the drip, and then collect an aPTT level every 6 hours per protocol to adjust the infusion rate as needed.
The other choices are wrong because:
• Vital signs: Although vital signs are important to monitor for any patient, they are not specific to Heparin therapy. Heparin does not affect blood pressure, heart rate, respiratory rate, or temperature directly.
• PT/INR: These are coagulation tests that measure the extrinsic pathway of clotting, which is affected by Vitamin K antagonists such as Warfarin. Heparin does not affect the PT/INR levels, so they are not relevant for Heparin therapy.
• EKG: An electrocardiogram (EKG) is a test that measures the electrical activity of the heart. It can help diagnose cardiac arrhythmias, ischemia, infarction, electrolyte imbalances, and other cardiac conditions.
Heparin does not affect the electrical conduction of the heart, so an EKG is not necessary before starting Heparin therapy

Correct Answer is C
Explanation
Warfarin is an anticoagulant that inhibits the synthesis of vitamin K-dependent clotting factors. The INR is a standardized measure of the prothrombin time (PT), which reflects the degree of anticoagulation.The therapeutic range for INR is 2 to 3 for most conditions, and higher for some mechanical heart valves.
Choice A) Activated partial thromboplastin time (aPTT) is wrong because it is used to monitor heparin therapy, not warfarin therapy.
Heparin is another anticoagulant that works by activating antithrombin III, which inhibits thrombin and factor Xa.The therapeutic range for aPTT is 1.5 to 2.5 times the normal value, which is 30 to 40 seconds.
Choice B) Prothrombin time (PT) is wrong because it is not a standardized measure of the warfarin effect.
The PT can vary depending on the reagents and methods used by different laboratories.The INR was developed to eliminate this variability and provide a consistent measure of the warfarin effect.
Choice D) Platelet count is wrong because it is not affected by warfarin therapy.
Warfarin does not affect the number or function of platelets, only the clotting factors.Platelet count can be used to monitor other conditions that affect hemostasis, such as thrombocytopenia or thrombocytosis.
Correct Answer is A
Explanation
Omeprazole is a proton pump inhibitor (PPI) that reduces the production of stomach acid.
Dabigatran is an anticoagulant that prevents blood clots from forming.
Both drugs can increase the risk of bleeding in the gastrointestinal tract, especially in clients with peptic ulcer disease.Therefore, they should not be used together unless absolutely necessary.
Choice B. Ranitidine is wrong because ranitidine is a histamine-2 receptor antagonist (H2RA) that also reduces the production of stomach acid, but to a lesser extent than PPIs.Ranitidine does not interact significantly with dabigatran and does not increase the risk of bleeding.
Choice C. Sucralfate is wrong because sucralfate is a mucosal protectant that forms a barrier over ulcers and protects them from acid and enzymes.Sucralfate does not affect the coagulation system and does not increase the risk of bleeding.
Choice D. Misoprostol is wrong because misoprostol is a synthetic prostaglandin that inhibits gastric acid secretion and increases bicarbonate and mucus production.
Misoprostol is used to prevent ulcers in clients who take NSAIDs, which can cause ulcers and bleeding.
Misoprostol does not interact with dabigatran and does not increase the risk of bleeding.
