Final answer:
Intramuscular and intravenous injections are avoided in pediatric clients due to the associated pain and unpredictable absorption. (options 1 & 2 are the correct answers).
Step-by-step explanation:
The injections that are avoided in pediatric clients because of the associated pain and unpredictable absorption are intramuscular and intravenous. In pediatric clients, intramuscular injections are often avoided due to the associated pain and unpredictable absorption. The pain from the needle insertion into the muscle can be distressing for children, and factors like muscle mass and activity levels can affect the absorption rate, leading to variability in drug effects.
Intramuscular injections involve injecting medication into the muscle layer, which can be painful for pediatric clients. Intravenous injections are administered directly into a vein, and their absorption can be unpredictable in children.
On the other hand, subcutaneous injections (injecting medication under the skin) and intradermal injections (injecting medication into the skin) are generally preferred for children as they cause less pain and have more predictable absorption.
