A nurse is preparing to administer amoxicillin 500 mg PO four times a day to a client. The amount available is amoxicillin suspension 250 mg/5 mL. How many mL should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Testing new nurses for exposure to tuberculosis is an example of secondary prevention. Secondary prevention aims to detect and treat diseases early in their course to prevent progression. Testing for tuberculosis exposure helps identify the disease early so that treatment can begin promptly.

Choice B reason: Providing treatment for clients who have chronic obstructive pulmonary disease is an example of tertiary prevention. Tertiary prevention focuses on managing and improving the quality of life for individuals with chronic diseases. It aims to reduce the impact of the disease and prevent complications.

Choice C reason: Performing screening for sexually transmitted infections is an example of secondary prevention. Screening helps detect infections early, allowing for timely treatment and reducing the spread of the disease.

Choice D reason: Administering influenza immunizations at a local health fair is an example of primary prevention. Primary prevention aims to prevent diseases before they occur by reducing risk factors and promoting health. Immunizations help prevent the onset of influenza.

Choice A reason: Aspirating for a blood return before depressing the plunger is not recommended when administering enoxaparin. Enoxaparin is given subcutaneously, and aspiration is not necessary for subcutaneous injections. Aspiration can cause tissue damage and increase the risk of bleeding.

Choice B reason: Inserting the needle at a 45-degree angle is appropriate for subcutaneous injections if the patient has limited subcutaneous tissue. However, for enoxaparin, the preferred angle is 90 degrees to ensure the medication is delivered into the subcutaneous tissue.

Choice C reason: Not expelling the air bubble in the prefilled syringe is correct. The air bubble in the prefilled syringe of enoxaparin is designed to ensure the entire dose is administered and to prevent leakage of the medication. Expelling the air bubble can result in an incomplete dose.

Choice D reason: Administering the medication 2.54 cm (1 inch) from the umbilicus is correct for subcutaneous injections in the abdomen. However, this statement alone does not address the specific consideration of the air bubble in the prefilled syringe, which is crucial for enoxaparin administration.
