What is the usual route for giving an insulin injection?

The nurse should administer 0.5 mL to the patient.

This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:

2 mg / 1 mL = 1 mg / x mL

Cross-multiplying and solving for x gives:

x = 0.5 mL

Therefore, the nurse should administer 0.5 mL of Stadol injection to deliver 1 mg of the medication to the patient.

Subcutaneous injection is the usual route for giving insulin because it allows the medication to be absorbed slowly and steadily into the bloodstream. Subcutaneous injection involves inserting a needle into the faty layer of tissue under the skin, usually in the abdomen, upper arm, thigh, or butock.

Intramuscular injection is not the usual route for giving insulin because it may cause rapid and unpredictable absorption of the medication, which can lead to hypoglycemia or hyperglycemia. Intramuscular injection involves inserting a needle into the muscle tissue, usually in the deltoid, vastus lateralis, or ventrogluteal area.

Intraosseous injection is not the usual route for giving insulin because it is reserved for emergency situations when intravenous access is not available. Intraosseous injection involves inserting a needle into the bone marrow, usually in the tibia or humerus.

Intradermal injection is not the usual route for giving insulin because it is mainly used for diagnostic tests, such as tuberculin skin test or allergy test. Intradermal injection involves inserting a needle into the dermis, which is the layer of skin just below the epidermis, usually in the forearm or upper back.
