MODULE 1
• What are the BON rules and regulations for prescriptive authority for the
advance practice nurse?
• Texas is very restricted
• Describe the pharmacokinetic processes of absorption, distribution,
metabolism and elimination and how differences in these areas affect drug action.
• Absorption
• Drug’s movement from the site of administration into the blood.
• Distribution
• Drug’s movement from the blood into the interstitial space of tissues
and from there into cells.
• Metabolism
• Biotransformation is the enzymatically mediated alteration of drug
structure.
• Elimination
• Combination of metabolism and excretion
• Discuss the impact of food on drug absorption, drug metabolism and on drug
toxicity and action—as well as the timing of drug administration.
LIFESPAN
,2|Pag e
• Hepatic metabolism and GFR increase during pregnancy, dosages of
some drugs may need to be increased.
• Rate of albumin to water decreases
• Third trimester: Renal blood flow is doubled and renal excretion is
accelerated (drugs excreted rapidly)
• Tone and mobility of bowel decrease
• Prolongation of drug effects Total (½ life increases)
Understand stages of development in pregnancy
• Conception: through week 2
• Embryonic period: week 3-week 8
a) Gross malformations can be produced by teratogens
• Fetal period: week 9-delivery
• Understand pregnancy labeling
• 3 categories now
a) Pregnancy, lactation, male & female reproductive potential
• How do you decrease risk in the infant during breastfeeding?
• Take meds immediately after breastfeeding, avoid drugs that have
long half-lives, choose drugs that tend to be excluded from milk, avoid drugs
that are known to be hazardous.
• How do pediatric patients differ in their response to medications?
, 3|Pag e
• Absorption
a) Oral?
• Neonates: drug remain in the stomach longer which increases the
levels, low acidity can affect the absorption of acid labile drugs
b) Parenteral?
• Reponses are slow and erratic.
• Infancy: absorption is more rapid than in neonates & adults
• Best avoided in infants
c) Transdermal?
• Greater skin permeability which increases topical drug absorption and
increases the risk for toxicity
• Distribution
A) Protein binding
1. Neonates: less protein-binding—increased availability of highly protein
bound drugs such as phenytoin, diazepam, and phenobarbital. Reduced dosages
needed in these highly bound drugs.
b) Blood Brain Barrier
1. Not fully developed at birth, drugs have easy access to the CNS, doses
should be reduced.
• Metabolism
a) Hepatic function?
