Q

Discuss Absoption

A

process by which a drug is transferred from its site of entry into the body to the bloodstream May be slowed due to: ICF (increased or decreased?) Gastric pH (increased or decreased?) Gastric blood flow and motility (increased or decreased?) Metabolism and drug absorption (increased or decreased?)

Q

Discuss distribution

A

Distribution occurs after the drug has been absorbed into the bloodstream and the drug is distributed throughout the body, becoming available to body fluids and body tissues Considerations: Changes in circulation Membrane permeability Body temperature Tissue structure Dehydration and hypoalbuminemia decrease drug distribution

Q

Drug Excretion

A

Kidneys excrete most drugs - although changes associated with aging, disease or other factors that impair the functioning of the kidneys can decrease their ability to excrete drugs. In this case, the drug package must list specific implications

Safety considerations for analgesics
Older adults may present differently regarding pain Start low and go slow Titrate and watch for adverse reactions (all meds)
26
Considerations for Anticoagulants
Anticoagulants (Heparin & Coumadin are common) High risk for bleeding Vitamin K (antidote) Monitor blood levels
