The patient has been receiving heparin therapy for deep vein thrombosis (DVT). The patient’s activated partial thromboplastin time (aPTT) result is 90 seconds (therapeutic range: 60-80 seconds). What will be included in patient care? (Select all that apply.).

Assessing for signs and symptoms of bleeding

Continuing heparin therapy at current rate

Decreasing heparin therapy per protocol

Holding heparin therapy per protocol

Increasing heparin therapy per protocol.

Answer and Explanation

Correct Answer : A,D

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.

Correct Answer is D

Explanation

The correct answer is choice D) Use a soft-bristled toothbrush.

This is because enoxaparin (Lovenox) is an anticoagulant that prevents blood clots by thinning the blood.Therefore, patients who take enoxaparin should avoid activities that can cause bleeding, such as using a hard-bristled toothbrush, flossing, shaving, or cutting their nails.

Choice A) Avoid foods that are high in vitamin K is wrong because vitamin K interacts with warfarin, another anticoagulant, but not with enoxaparin.Vitamin K helps the blood clot, so patients who take warfarin should avoid foods that are high in vitamin K, such as leafy green vegetables, broccoli, or liver.

Choice B) Administer injections into areas with decreased subcutaneous tissue is wrong because enoxaparin should be injected into areas with adequate subcutaneous tissue, such as the abdomen or the thighs.Injecting into areas with decreased subcutaneous tissue can cause bruising, pain, or hematoma formation.

Choice C) Massage injection sites after administration is wrong because massaging the injection sites can cause bleeding, bruising, or irritation.Patients who take enoxaparin should not rub or press on the injection sites after administration.

A. Activated partial thromboplastin time (aPTT) B. Prothrombin time (PT) C. International normalized ratio (INR) D. Platelet count.

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.
