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.

Nitroglycerin sublingual is a medication that is used to treat chest pain or angina by relaxing the blood vessels and reducing the oxygen demand of the heart.A common side effect of nitroglycerin sublingual is headache, which may be severe and throbbing.Headache is often a sign that the medication is working.Other possible side effects include flushing, dizziness, lightheadedness, nausea, vomiting, fast heart rate, numbness, tingling, burning pain, rash, hives, sweating, pale skin, difficulty breathing and allergic reaction.
Choice A is wrong because nausea is not the most common adverse effect of nitroglycerin sublingual.Nausea may occur in some people, but it is usually mild and transient.
Choice B is wrong because bradycardia (slow heart rate) is not a common adverse effect of nitroglycerin sublingual.Nitroglycerin sublingual may cause tachycardia (fast heart rate) in some people as a result of vasodilation and reflex stimulation of the heart.
Choice C is wrong because hypertension (high blood pressure) is not a common adverse effect of nitroglycerin sublingual.Nitroglycerin sublingual may cause hypotension (low blood pressure) in some people due to its vasodilating action.Hypotension may lead to lightheadedness, fainting or shock in severe cases.
The normal range for blood pressure is less than 120/80 mmHg for adults.
The normal range for heart rate is 60 to 100 beats per minute for adults.

Explanation
Thiazide diuretics are sulfa-containing drugs and can cause allergic reactions in patients who are sensitive to sulfa compounds.These reactions can include headaches, rash, hives, swelling of the mouth and lips, wheezing or trouble breathing, asthma attack, and anaphylaxis.
Choice A is wrong because iodine is not a component of thiazide diuretics and is not related to sulfa allergy.
Choice B is wrong because latex is not a component of thiazide diuretics and is not related to sulfa allergy.
Choice C is wrong because shellfish is not a component of thiazide diuretics and is not related to sulfa allergy.
Shellfish allergy is usually caused by a protein called tropomyosin, not by iodine or sulfa compounds.
Thiazide diuretics are drugs that inhibit the reabsorption of sodium and water in the distal convoluted tubule of the kidney, leading to increased urine output.They are used to treat hypertension, edema, heart failure, and some kidney diseases.Some examples of thiazide diuretics are hydrochlorothiazide, chlorthalidone, and indapamide.
