Which of the following anti-lipidemic drugs are the most potent antilipidemic agents, and have proven to lower the risk of Myocardial Infarction?

This is because enoxaparin is administered subcutaneously, which means under the skin, and the needle should be inserted fully into the skin to ensure proper delivery of the drug.

Choice A is wrong because aspirating (pulling back on the plunger) after inserting the needle is not recommended for subcutaneous injections of enoxaparin, as it may increase the risk of bleeding or bruising.

Choice B is wrong because administering the injection in the client’s thigh is not the preferred site for enoxaparin.The preferred site is the abdomen, at least 2 inches away from the navel, as it has more fatty tissue and less blood vessels than other areas.

Choice D is wrong because expelling the air bubble from the prefilled syringe is not necessary for enoxaparin.The air bubble helps to ensure that the entire dose of enoxaparin is injected and prevents blood from entering the syringe.

Normal ranges for enoxaparin dosage depend on the indication and the patient’s weight, but for prophylaxis of deep vein thrombosis after hip arthroplasty, the usual dose is 40 mg once a day for 3 weeks.

The prefilled syringe of enoxaparin 40 mg/0.4 ml contains the correct dose for this indication.

This is because a PTT (partial thromboplastin time) test measures how long it takes for blood to clot. A normal PTT range is between 25 to 35 seconds. If the patient’s PTT is too long and greater than 80 seconds, it means their blood is taking too long to clot and they are at risk of bleeding excessively. The nurse should notify the doctor and expect an order to hold the dose of heparin, a type of anticoagulant that prevents blood clots by prolonging the PTT.
Choice A is wrong because continuing with the same dosage of heparin would not correct the prolonged PTT and could cause more bleeding problems for the patient.
Choice C is wrong because increasing the dosage of heparin would further prolong the PTT and increase the risk of bleeding.
Choice D is wrong because decreasing the dosage of heparin would not be enough to bring the PTT back to normal range and would still pose a bleeding risk for the patient.
