In the context of safe medication administration, what role does the MAR (Medication Administration Record) play?
It provides a comprehensive list of medications to be administered
It schedules follow-up appointments for patients
It serves as a tool for patient education about side effects
It verifies the patient's insurance coverage for medications
The Correct Answer is A
A. It provides a comprehensive list of medications to be administered: The MAR is a legal and clinical document that lists all prescribed medications, their dosages, routes, and times of administration. It serves as a primary reference for nurses to ensure accurate and timely medication delivery.
B. It schedules follow-up appointments for patients: The MAR does not include scheduling of appointments; its function is focused solely on medication management and administration.
C. It serves as a tool for patient education about side effects: While the MAR may indirectly support education by listing medications, it is not intended as an educational tool. Patient teaching requires separate counseling and documentation.
D. It verifies the patient's insurance coverage for medications: Insurance verification is handled through pharmacy and billing systems, not the MAR. The MAR’s purpose is clinical accuracy and safety in administering medications.

Correct Answer is A
Explanation
A. Tuberculin syringes lack unit calibrations specific to insulin: Tuberculin syringes are marked in milliliters, not insulin units, which makes them inappropriate for accurate insulin dosing. Using them increases the risk of dosing errors and potential hypoglycemia or hyperglycemia.
B. Tuberculin syringes do not have a needle attached: Tuberculin syringes typically come with a needle or have compatible needles available. Lack of needle is not the main safety concern for insulin administration.
C. Tuberculin syringes can only be used for intramuscular injections: Tuberculin syringes can be used for subcutaneous or intradermal injections; their limitation is not route but the calibration for precise dosing, which is unsuitable for insulin.
D. Tuberculin syringes are too large for insulin administration: Tuberculin syringes are small (1 mL), but size is not the main issue. The critical concern is that they are not calibrated in insulin units, making precise dosing unsafe.
Correct Answer is C
Explanation
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.
