a. The administration of medicine by injection requires equipment (needles and syringes) that is sterile, accurate in measuring dosage, convenient to use, and that will produce as little discomfort and/or hazard for the patient as possible.

A needle and syringe are used to introduce suitable liquid preparations of drugs directly into the body tissue or blood vessels. Because of the accuracy of these methods of administration, these injections provide the patient with a more precise amount of drug and a more rapid onset of drug action than with oral medications.

b. Patient safety is a critical factor for the basic medical specialist. Aseptic techniques must be strictly maintained during the preparation and administration of a drug.

Foreign particles or other types of contamination on a needle could be injected directly into the body. Infection may be introduced through the needle hole in the skin. Irreparable damage to major nerves or other structures may occur due to improper technique or a dull needle.

Needles and syringes are controlled items. The medical specialist is responsible for the security and control and ultimate disposal of this equipment.
