NSG-318 Exam 1 Questions with Verified
Correct Answers
pharmacology
study of drugs
drug
Chemical that affects physiologic process of a living organism
Nursing Implications
The concepts that a nurse must include when they are safely administering medication
Identify the various routes of medication administration
Sublingual (buccal), oral, transdermal (topical creams/ lotions), instillation (eye
drops/sprays), inhalation, nasogastric and gastrostomy tubes, suppositories, parenteral
6 rights of administration
1. Right patient
2. Right drug
3. Right dose
4. Right route
5. Right time and frequency
6. Right documentation
List the components of a drug label
Chemical Name: structure of the drug
Generic name: the official drug name
Brand/ trade name: the easier proprietary name
,Active and inactive ingredients
Warning/ possible side effects
Directions on use as well as what the drug is used for/ what it helps treat
normal vital signs (BP)
120/80
Pharmacokinetics
what the body does to the drug
pharmacokinetic phases
-absorption (drug movement from GI tract into bloodstream)
-distribution (protein binding, free drugs, BBB)
-metabolism (1/2 life, loading dose; liver)
-excretion (elimination, kidneys, creatinine clearance, BUN, GFR
factors that affect drug excretion
-drugs that affect renal excretion/decrease CO
-diuretic use
-drugs that use same excretion method
-change of urine pH
-pt. with decreased renal or hepatic function
1/2 life (T 1/2)
Time it takes to get rid of half of the drug; gives us good time to administer rest of the dose
and when we can expect to see side effects
Loading dose
, use of a higher dose than what is usually used for treatment to allow the drug to reach the
critical concentration sooner
photosensitivity
- sensitivity to light
- ranges from the ability to orient to the sun to the ability to see
factors affecting absorption
Blood circulation
Pain, stress
Food texture, fat content, temperature
pH
Route of administration
factors affecting bioavailability
Drug form
Route of administration (IV is best)
Gastric mucosa and motility
Administration with food and other drugs
Changes in liver metabolism
what can affect absorption
Blood circulation, pain, stress, pH, administration route, and food texture, fat content, and
temperature
What is bioavailability?
The percentage of administered drug available for activity.
