NR 293 Pharmacology for Nursing
Content Areas to Review for Exam 1
1/18/2021
All Reading Assignments, (ATI), Lecture Materials, handouts are all testable material. Be prepared for
math question such as dosage calculations.
Apply Nursing Considerations (to the drugs/drug classes listed below)
Assessments to include vital signs, physical assessment, labs
Drug administration: safety, route considerations
Drug toxicity (signs/symptoms) and antidote if applicable
Patient teaching (ex. nutrition, adverse effects, infusion considerations, laboratory reviews)
Health care collaboration
Nursing process
Things to Consider:
- Know the GENERIC names - Grapefruit juice is usually a good bet
- Common Side Effect = HEADACHE/ GI UPSET
- herbal supplements that start with G (ex. garlic, ginger, gingko biloba) risk of bleeding
- most meds are contraindicated for pregnancy
- pt should not stop meds suddenly & if dose is missed don’t double dose
- alcohol should not be consumed w/ most meds - gram + = staph & strep

Chapter 2: Pharmacological Principles and Chapter 5: Medication Errors
*4 Phases of Pharmacokinetics:
1. Absorption - depends on route of administration
EX. Oral meds (takes a while) considerations = food in stomach, pH of GI, liquid form vs
enteric-coated aka extended release
& *first pass effect (oral meds are inactivated on their 1st pass through liver, may
need to give pt higher dose
Sublingual absorbs very quickly, pt should wait until its completely absorbed
Inhalation absorbed very quickly, travels through alveoli
, Intradermal/Topical slow & gradual rate of absorption
IM absorption depends on solubility of the med IV is immediate absorption
2. Distribution (med travels to site of action) - binding proteins are req. [ex. albumin]
3. Metabolism (med is activated or broken down) - due to enzymes; primarily happens in liver &
kidneys, lungs, bowel, blood
Infants - organs are immatures so metab. doesn’t happen effectively = high risk of
toxicity
Older adults’ liver/kidneys dysfunction impacts metab. & slows it down also higher
risk for toxicity
4. Excretion - primarily happens through kidneys
Minimum Effective Concentration (MEC) /Therapeutic Index
- we want to attempt to keep plasma levels between the minimum effective concentration & toxic
concentration
- certain meds have a high therapeutic index (TI) aka big range between MEC & toxic concentration
-other meds have low TI making therapeutic level & toxic level very close together (ex. vancomycin)
there’s a risk for toxicity so blood draws are req. to check trough & peak levels
assuring you’re not getting into toxic range
1/2 Life = period of time needed for med to be reduced by 50%
if med has longer ½ life (stays in body longer) have risk of toxicity
*Agonists vs. Antagonist Meds
Agonist = helps produce an action [ex. morphine binds w/ opioid receptors]
Antagonist = blocks normal receptor, opposing action
Routes of Administration & Nursing Considerations
Oral Med = pt sitting upright (Fowler’s position) may need to mix in applesauce to facilitate swallowing
- never chew enteric coated meds - avoid grapefruit juice - administer on empty stomach
- liquid form of meds may facilitate swallowing
Sublingual = make sure med is fully absorbed before pt eats or drinks, do not swallow
Transdermal = assure skin is hairless, clean & thoroughly dry; also rotate sites (prevents irritation)
Eye Med = use surgical aseptic technique; drop med in center conjunctival sac w/ gentle pressure for
30-60 sec @ nasolacrimal duct
Ear Med = lay pt on unaffected side *Rem. for Adults pull auricle & (out) Kids is and (back)
