Final answer:
Z-track injections are primarily used for intramuscular analgesics. This method prevents medication leakage into subcutaneous tissues and thus potential irritation or discomfort. The route selection of administration can greatly influence the medication’s effectiveness and potential side effects.
Step-by-step explanation:
The Z-track injection is a method of intramuscular injection used to prevent medication from leaking back up the needle track and into subcutaneous tissues. The answer to the question, 'Which type of medications are given by Z-track injection?' would be b) Intramuscular analgesics.
These are often administered this way because it reduces the likelihood of mediations entering subcutaneous tissues, which can lead to pain and irritation.
Medications like intravenous antibiotics are delivered directly into the bloodstream for immediate effect, while subcutaneous anticoagulants are typically injected into the fatty tissue layer beneath the skin.
Intradermal vaccines are administered into the dermis, the layer of skin below the epidermis.
The route of medication administration plays a significant role in its efficacy, absorption and side effects. The Z-track method is preferred for irritating or discoloring medications and helps to seal the medication deeply into muscle tissue.
