Pharmacology Routes of Admin #3

Question

Which medication administration route(s) is/are used for depot hormone preparations? Select all that apply.

Answers

  1. Oral
    • Rationale:

      This is not the correct answer because oral preparations are absorbed more slowly and with great variability compared to parenteral therapy. IM administration of depot preparations is most appropriate since it can be placed in a muscle and gradually be released into the system for therapeutic effect without the need for multiple injections.

  2. Enteral
    • Rationale:

      This is not the correct answer because enteral or oral route is the route which utilizes the gut for absorption. Oral or enteral preparations are absorbed more slowly and with great variability compared to parenteral therapy. IM administration of depot preparations is most appropriate since it can be placed in a muscle and gradually be released into the system for therapeutic effect without the need for multiple injections.

  3. Intramuscular
    • Rationale:

      This is the correct answer because the intramuscular route (placed in the muscle) and subcutaneous routes (placed in the fat tissue) are both suitable for depot preparations, which effects can last for up to months. Depot preparations are medications which are absorbed slowly over an extended period of time. The advantage of depot preparations is that it decreases the need for multiple injections.

  4. Intravascular
    • Rationale:

      This is not the correct answer because the intravascular route has instantaneous absorption, with rapid onset of the IV therapy. Depot preparations are medications which are absorbed slowly over an extended period of time, therefore, the intravascular route is inappropriate for depot preparations.

  5. Subcutaneous
    • Rationale:

      This is the correct answer because the intramuscular route (placed in the muscle) and subcutaneous routes (placed in the fat tissue) are both suitable for depot preparations, which effects can last for up to months. Depot preparations are medications which are absorbed slowly over an extended period of time. The advantage of depot preparations is that it decreases the need for multiple injections.

Overview

The intramuscular and subcutaneous route of medication administration has a unique purpose. The use of absorption through tissue, whether muscle or subcutaneous tissue, has unique uses in medication administration to control the absorption rate for certain medication preparations.

Explanation

Learning Outcomes

Depot preparations are medications which are absorbed slowly over an extended period of time. The intramuscular route (placed in the muscle) and subcutaneous routes (placed in the fat tissue) are both suitable for depot preparations, which effects can last for up to months. Certain antibiotics and hormones are examples of depot preparations. The advantage of depot preparations is that it decreases the need for multiple injections.

Test Taking Tip

When trying to remember information and concepts in nursing, try to remember things that are unique about certain things, things that make it stand out from the rest. Furthermore, consider remembering when concepts are similar to clump learn and make the amount of things to learn less.
