When converting 1 ounce to milliliters, what is the correct metric equivalent?

A. It identifies whether the medication is generic or brand name: While the label may indicate the medication name, the dosage strength specifically does not determine whether the drug is generic or brand; it focuses on the amount of active ingredient per unit.

B. It provides storage instructions for the medication: Storage instructions are typically included on the label separately, but the dosage strength itself does not guide storage requirements.

C. It helps calculate the total volume of medication needed: Dosage strength can assist in calculations, especially for liquid medications, but its primary purpose is not volume calculation; calculations depend on both prescribed dose and concentration.

D. It ensures the nurse administers the correct amount of medication: The dosage strength indicates how much active drug is present per tablet, capsule, or milliliter. Knowing this allows the nurse to administer the correct dose safely, preventing underdosing or overdosing and ensuring therapeutic effectiveness.

A. Deltoid muscle: The deltoid is primarily used for intramuscular injections, not subcutaneous injections. Using it for subcutaneous medication may result in improper absorption and increased discomfort.

B. Forearm: The forearm is generally reserved for intradermal injections, such as allergy or tuberculosis testing, and is not ideal for subcutaneous medication due to limited subcutaneous tissue.

C. Abdomen: The abdomen is the preferred site for subcutaneous injections because it has a large, easily accessible layer of adipose tissue, allowing consistent and predictable absorption of medications like insulin and heparin.

D. Vastus lateralis: The vastus lateralis muscle, located in the thigh, is typically used for intramuscular injections. It is not preferred for subcutaneous administration as absorption may be less consistent.
