A nurse is preparing to administer enoxaparin (Lovenox) to a client who has a pulmonary embolism.
Which of the following actions should the nurse take?
Inject the medication into the deltoid muscle.
Expel the air bubble from the prefilled syringe.
Pinch the skin at the injection site.
Apply pressure to the injection site after administration.
The Correct Answer is C
Pinch the skin at the injection site.
This is because enoxaparin is a low molecular weight heparin that is administered subcutaneously, which means under the skin. Pinching the skin helps to create a fold of tissue that can be injected with the medication. Expelling the air bubble from the prefilled syringe is not necessary, as it helps to prevent leakage of the medication after injection. Injecting the medication into the deltoid muscle is wrong, as enoxaparin should not be given intramuscularly. Applying pressure to the injection site after administration is also wrong, as it can cause bruising or hematoma.

Correct Answer is A
Explanation
The correct answer is choice A. Elevated D-dimer level.
D-dimer is a fibrin degradation product that is released when a blood clot is dissolved.A high level of D-dimer indicates an increased likelihood of blood clots, such as pulmonary embolism.A normal D-dimer level (below 500 ng/mL) can rule out pulmonary embolism in patients with low or moderate clinical pretest probability.
Choice B is wrong because decreased platelet count is not associated with pulmonary embolism.Platelet count may decrease after pulmonary embolism due to platelet activation and consumption, but it is not a risk factor for clot formation.
Choice C is wrong because low hematocrit level is not associated with pulmonary embolism.
Hematocrit level may decrease due to blood loss, hemolysis, or dilution, but it does not affect the risk of clot formation.
Choice D is wrong because high prothrombin time is not associated with pulmonary embolism.
Prothrombin time measures the time it takes for blood to clot in the presence of vitamin K-dependent factors.
A high prothrombin time indicates a deficiency or inhibition of these factors, which may increase the risk of bleeding, not clotting.
Normal ranges for D-dimer, platelet count, hematocrit, and prothrombin time may vary depending on the laboratory and the method used, but generally they are:
• D-dimer: <500 ng/mL
• Platelet count: 150-450 x 10^9/L
• Hematocrit: 36-48% for females, 40-54% for males
• Prothrombin time: 11-13 seconds
Correct Answer is A
Explanation
The correct answer is choice A.“I should avoid smoking cigarettes.” Smoking cigarettes increases the risk of blood clots and deep vein thrombosis (DVT), which can lead to pulmonary embolism (PE) if the clot travels to the lungs.Smoking also damages the blood vessels and reduces oxygen levels in the blood.
Choice B is wrong because aspirin is not a recommended medication for preventing PE.Aspirin is a type of antiplatelet drug that prevents platelets from sticking together and forming clots, but it does not affect the clotting factors in the blood that are involved in DVT and PE.Anticoagulants, also known as blood thinners, are the preferred medications for preventing and treating DVT and PE, as they prevent further clot formation and decrease the chances of new clots.
Choice C is wrong because limiting fluid intake can increase the risk of dehydration, which can thicken the blood and make it more prone to clotting.Drinking plenty of water is important for preventing DVT and PE, especially when traveling or being immobile for long periods of time.
Choice D is wrong because wearing tight-fitting socks can restrict blood flow in the legs and increase the risk of DVT and PE.
