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.

Answer and Explanation

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 A

Explanation

The correct answer is choice A) Activated partial thromboplastin time (aPTT).This is because aPTT is the most commonly used laboratory test to monitor the therapeutic effect of heparin therapy.

Heparin is an anticoagulant that inhibits the formation of thrombin and fibrin, which are essential for blood clotting.Heparin therapy is indicated for the treatment of deep vein thrombosis (DVT), which is a condition where blood clots form in the deep veins of the legs or pelvis.

Choice B) Prothrombin time (PT) is wrong because PT is used to monitor the therapeutic effect of warfarin therapy, not heparin therapy.

Warfarin is another anticoagulant that inhibits the synthesis of vitamin K-dependent clotting factors.Warfarin therapy is also indicated for the treatment of DVT, but it has a different mechanism of action and monitoring than heparin therapy.

Choice C) International normalized ratio (INR) is wrong because INR is a standardized way of reporting PT results that accounts for the variability of different laboratory methods.INR is also used to monitor the therapeutic effect of warfarin therapy, not heparin therapy.

Choice D) Platelet count is wrong because platelet count is not directly affected by heparin therapy.However, platelet count should be monitored periodically in patients receiving heparin therapy to detect heparin-induced thrombocytopenia (HIT), which is a rare but serious complication of heparin therapy that causes a drop in platelet count and an increased risk of thrombosis.

Choice E) Hemoglobin is wrong because hemoglobin is not directly affected by heparin therapy.However, hemoglobin should be monitored periodically in patients receiving heparin therapy to detect bleeding complications, which are the most common adverse effects of heparin therapy.

The normal range for aPTT is 25 to 35 seconds, but the therapeutic range for heparin therapy is usually 1.5 to 2.5 times the normal range, depending on the indication and protocol.

The normal range for PT is 11 to 13 seconds, and the therapeutic range for warfarin therapy is usually an INR of 2 to 3, depending on the indication and protocol

A. Assessing for signs and symptoms of bleeding B. Continuing heparin therapy at current rate C. Decreasing heparin therapy per protocol D. Holding heparin therapy per protocol E. Increasing heparin therapy per protocol.

Correct Answer is ["A","D"]

Explanation

A patient with a high aPTT result is at risk for bleeding, so assessing for signs and symptoms of bleeding is important.

Holding heparin therapy per protocol is also appropriate, as heparin is the cause of the prolonged aPTT.

The other choices are wrong because:

• Choice B is wrong because continuing heparin therapy at the current rate will increase the risk of bleeding and further prolong the aPTT.

• Choice C is wrong because decreasing heparin therapy per protocol is not enough to reverse the effects of heparin.

Heparin should be stopped until the aPTT returns to the therapeutic range.

• Choice E is wrong because increasing heparin therapy per protocol will worsen the situation and cause more bleeding and coagulation problems.

The normal range for aPTT is 25 to 35 seconds, and the therapeutic range for heparin therapy is 60 to 80 seconds.A result of 90 seconds indicates excessive anticoagulation and increased bleeding risk.
