Q

What are some lifespan considerations that should be taken into account when giving immune modulators to a child?

A

Should be used with caution - monitor closely for infection, GI, renal, hematological or CNS effects.

A

Teach proper injection technique.
Avoid infection and injury.
Contraindicated in pregnancy/lactation.

Q

What are some lifespan considerations that should be taken into account when giving immune modulators to older adults?

A

Their immune system is less efficient and less responsive hence they are more susceptible to the drug effect.
Monitor renal and liver function to determine dosage.
More susceptible to infection - teach infection and injury prevention.

Q

Why does children need higher doses of these drugs?

A

Due to the body surface to their body surface area to weight ratio and faster metabolism.

Older adults vice versa!

Q

TRUE/FALSE

Immune modulators may be given as an injection

A

TRUE.
We should teach the patient how to properly inject the medication and have them demonstrate how to do it. We should also educate family members on how to inject the patient should they be unable to do this themselves as well as educate on any adverse reactions to the injection site.

Q

What are interferons?

A

Proteins that are naturally released from human cells in response to viral invasion.
They act in multiple ways to prevent the spreading of a virus within the body.
They are excreted by an infected cell and goes into a non infected cell and make antibody proteins so that those cells cannot become infected.
May also stimulate phagocytes and T-cells and can fight tumors.
