A nurse is planning 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.
Expel the air bubble from the prefilled syringe before injection.
Administer the injection in the client's thigh.
Insert the needle completely into the client's tissue.
The Correct Answer is D
Choice A rationale
Aspiration is not recommended for subcutaneous injections because it can increase tissue damage and pain. Enoxaparin should be administered without aspiration.
Choice B rationale
Prefilled syringes of enoxaparin contain an air bubble to ensure the entire dose is administered. Expelling the air bubble before injection is not recommended.
Choice C rationale
Enoxaparin should be administered in the abdomen, at least 2 inches away from the umbilicus, to ensure proper absorption and effectiveness.
Choice D rationale
Enoxaparin should be administered subcutaneously, and the needle should be inserted completely to ensure the medication is delivered into the subcutaneous tissue.

Correct Answer is C
Explanation
Choice A rationale
Digoxin is a cardiac glycoside used for heart failure and arrhythmias, not a diuretic.
Choice B rationale
Spironolactone is a potassium-sparing diuretic, preventing hypokalemia.
Choice C rationale
Furosemide is a loop diuretic that can cause hypokalemia by increasing potassium excretion.
Choice D rationale
Captopril is an ACE inhibitor used for hypertension and heart failure, not a diuretic.
Correct Answer is A
Explanation
Choice A rationale
Lactated Ringers (LR) is an isotonic solution, which means it has the same osmolarity as blood plasma. This property makes LR suitable for rehydrating patients without causing a significant shift of fluids between compartments, maintaining the balance of electrolytes.
Choice B rationale
0.45% Sodium Chloride is a hypotonic solution, meaning it has a lower osmolarity compared to blood plasma. This type of solution would cause fluid to move into cells, potentially leading to cellular swelling.
Choice C rationale
Dextrose in Lactated Ringers is a hypertonic solution because the added dextrose increases the osmolarity. This solution can cause fluid to shift out of cells, leading to cellular shrinkage, which is not ideal for rehydration.
Choice D rationale
None of the above is incorrect because Lactated Ringers (LR) is indeed an isotonic solution.
