A nurse is preparing to administer subcutaneous enoxaparin 40 mg using a prefilled syringe of enoxaparin 40 mg/0.4 ml to an adult client following hip arthroplasty.
Which of the following actions should the nurse plan to take?
Aspirate carefully after inserting the needle into the client’s skin.
Administer the injection in the client’s thigh.
Insert the needle at 90 degrees.
Expel the air bubble from the prefilled syringe before injecting.
The Correct Answer is C
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.

Correct Answer is D
Explanation
Taking a loop diuretic with supper is not advisable because it can cause nocturia, which is the need to urinate frequently at night. This can disrupt sleep and affect quality of life.Loop diuretics should be taken in the morning or early afternoon to avoid this problem.
Choice A is wrong because weighing oneself each day before breakfast is a good way to monitor fluid balance and detect any signs of fluid retention or dehydration.This can help adjust the dose of the loop diuretic as needed.
Choice B is wrong because contacting the healthcare provider if shortness of breath returns is a sensible precaution and indicates awareness of the symptoms of worsening heart failure.Shortness of breath is caused by fluid accumulation in the lungs, which loop diuretics help to prevent or reduce.
Choice C is wrong because having a banana with breakfast every morning is a good source of potassium, which can help prevent hypokalemia, a common side effect of loop diuretics.Loop diuretics increase the excretion of potassium in the urine, which can lead to low blood levels of potassium and cause muscle weakness, cramps, fatigue, arrhythmias, and increased sensitivity to digoxin.
Correct Answer is C
Explanation
Exposure to cold temperatures should be avoided by the patient with peripheral vascular disease such as Raynaud’s disease.
This is because cold temperatures can trigger vasospasm, which is a sudden narrowing of the small arteries in the fingers or toes, limiting blood flow and causing pain, numbness and color changes.
Choice A is wrong because wearing warm mitten gloves can help prevent or reduce the severity of Raynaud’s attacks by keeping the hands warm.
Choice B is wrong because wearing socks can also help protect the feet from cold exposure and prevent or reduce Raynaud’s attacks.
Choice D is wrong because engaging in regular exercise can improve blood circulation and reduce the frequency and duration of Raynaud’s attacks.However, exercise should be done with caution and proper clothing to avoid injury or frostbite to the affected areas.
Normal ranges for peripheral vascular disease are not applicable, as it is a condition that affects the blood vessels and not a specific blood test or measurement.
However, some tests that can help diagnose peripheral vascular disease or its underlying causes are blood pressure measurement, ankle-brachial index, Doppler ultrasound, angiography, blood tests for cholesterol, glucose, clotting factors and inflammatory markers.
