Detailed Answers | 2026 Update | 100%
Correct - Rasmussen
Population most sensitive to to drug responses
Infants under one year, adults older than 65
Pharmacokinetic consideration of the peds population
Body Weight, immature liver/kidney function, greater risk for less bone growth, lower
BP, higher body content, immature blood brain barrier
Identify pharmacokinetic considerations of elderly
Decreased body water content, increased fat and gastric PH
Identify population at risk for adverse drug reactions
Children under one, elderly over 65, pregnant, kidney liver impairment, severe illness,
multiple medications
Identify ways to reduce medications errors
Scan barcodes, avoid abbreviations, safety checklist, environment that is non punitive,
encouraging families + patients to be active members of the healthcare team ( to help
identify mistakes)
Most common reason of fatal medications errors
Human factors, wrong route, communications mistake, drug name confusion
Pharmacodynamic tolerance
Effective concentration of a drug becomes abnormally high (have to increase the drug
to have the same effect)
, Tolerance
Decrease responsiveness to a drug as a result of repeated drug administration
Reduced therapeutic effect
One medication is going to increase metabolism or block the effect of the 2nd
medication
Increased adverse effects
The interactions of medications having the same adverse effects
(ex. aspirin, warfarin- increasing bleeding)
Increased therapeutic effects
Medications given purposely together enhances the effects
Drug interactions w/ grape juice
Increasing levels of the drug
(ex. statins are cholesterol, lowering drugs)
Narrow therapeutic index
Smaller range of safety, less safe to use.
Plasma drug levels to check for adverse effects
Wide therapeutic index
Indicated that a drug is relatively safe even in larger doses
Reduces adverse effect
Used to counteract from a drug
(ex. naloxone to treat morphine overdose)
How long dose it take for a drug to reach plateau level?
