Antibiotics Flashcards

1
Q

Antibiotics across the lifespan: CHILDREN

A

-kids are more sensitive to adverse effects
^monitor their hydration and nutrition when seeing diarrhea, nausea, vomiting, anorexia
-super infections, especially oral candidiasis (thrush)
-use caution as many of these meds have not established safety and efficacy for children
-some can cause harm to growing cartilage, bones, and teeth (tigecycline)
-double check doses
-patient education on when to use antibiotics (not for viral infections, administering the full course of the meds, and proper storage)

Q

Antibiotics across the lifespan: ADULTS

A

-only use as needed
-do not take antibiotics that were not prescribed to you
-don’t save antibiotics for future use
-Pregnancy/lactation: only use when benefit outweighs the risk
^tetracylines can damage teeth and bones: aminoglycosides can cause hearing loss

oral contraceptives are considered drug-drug interactions

Q

Antibiotics across the lifespan: OLDER ADULTS

A

they may present with different S/S of infection (many older adults don’t get fevers)
-obtaining a culture before providing medication is even more important
-more susceptible to adverse effects: monitor for hydration and nutrition if they’re having adverse effects of nausea, vomiting, anorexia, or diarrhea.
-only use as needed
-do not take antibiotics that were not prescribed to you
-don’t save antibiotics for future use
