NURS 251 Pharmacology Final Exam-with 100% verified
solutions-2025!!!!
1.
Sublingual: When rapid effect is needed right away Subcutaneous: Destroy
or inactivated in the GI Tract Intramuscular: Used for drugs with
poor oral absorption Topical: For local effects on skin and eyes
Pharmaceutics is the study of how various dosage forms influence the way in which the drug affects
the body/ Administration of dosage form, dissolution of drug into body/ manipulating chemical
compound.
Pharmacokinetics is the study of what the body does to the drug, including absorption, distribution,
metabolism, and excretion/ Absorption, distribution, metabolism, excretion.
Pharmacodynamics is the study of what the drug does to the body/ Drug- receptor interaction.
2. The drug naltrexone is given to prevent relapse or cravings in individuals who use opioids. It binds
to opioid receptors blocking endogenous agonist and other opioid drugs from binding and having an
effect. Naltrexone is a/an
Competitive agonist (binds to the same site of agonist)
3. Due to the many chronic diseases associated with aging the elderly can have decreased blood
flow to the liver. With age, there can also be a decrease in liver enzymes, which can increase the
duration of a drug in the patient’s systems. Which pharmacokinetic process is affected in this
scenario?
Metabolism (stored in the body)/ cytochrome P-450 enzymes/ liver/ Grapefruit and statins
4. When the combined effect of two drugs is greater than the sum of the individual effects it
refers to
Synergism: When the combined effect of two drugs is greater than the sum of
,their individual effects
, 5. True or false. Schedule I drugs have a low abuse potential and are accepted medical use
False via having a high abuse potential and no accepted medical use
6. Michael is a 2 year old male with a history of a liver cirrhosis problem caused by biliary atresia. While
on a family vacation, Michael developed a fever, and his parents found children’s Motrin as the only
antipyretic option at eh hotel convenience shop. Is this an appropriate for Michael? Explain why or why
