WGU D027 OA
Pass The WGU D027 OA – Advanced Pathopharmacological Foundations
exam 2025/2026 with confidence. This exam resource features questions in
areas like: drug mechanisms, therapeutic effects, adverse reactions, and
clinical decision-making. This study guide is perfect for MSN, DNP, and
nurse practitioner students preparing for competency-based assessments in
advanced pharmacology.
What are some physical changes from Alzheimer's dementia? .......
ANSWER ......- Brain shrinks dramatically; nerve cell death and tissue
loss
- Cardinal signs: plaques (abnormal clusters of protein fragments) and
tangles (twisted strands of another protein)
How is Alzheimer's treated? ....... ANSWER ......- There is no cure, but
there are pharmacological and non-pharmacological treatments
- Cholinesterase inhibitors
- Memantine (namenda)
, What are cholinesterase inhibitors prescribed for? ....... ANSWER ......-
To treat symptoms related to memory, thinking, language, judgment, and
other processes
Page | 2 - Helps delay or slow the worsening of symptoms
What does cholinesterase inhibitors do? ....... ANSWER ......- Prevent the
breakdown of acetylcholine, a chemical messenger that is important for
learning and memory
- Supports communication among nerve cells by keeping the
acetylcholine high
What are some commonly prescribed cholinesterase inhibitors? .......
ANSWER ......- Donepezil (aricept)
- Galantamine (razadyne)
- Rivastigmine (exeleon)
Which cholinesterase inhibitor can be used for all stages of Alzheimer's?
....... ANSWER ......- Donepezil (aricept)
Which cholinesterase inhibitor can be used for mild-to-moderate stages of
Alzheimer's? ....... ANSWER ......- Galantamine (razadyne)
- Rivastigmine (exeleon)
Which cholinesterase inhibitor can be used for mild-to-moderate
Alzheimer's and Parkinson's? ....... ANSWER ......- Rivastigmine
(exeleon)
, What medication combination is used to treat moderate-to-severe
Alzheimer's? ....... ANSWER ......- Memantine (namenda) and donepezil
Page | 3 (aricept)
What is memantine (namenda) used for? ....... ANSWER ......- Prescribed
to improve memory, attention, reason, language, and the ability to
perform simple tasks
- Can be used alone or with other Alzheimer's disease treatments
How does memantine (namenda) work? ....... ANSWER ......- Regulates
the activity of glutamate, a chemical involved in information processing,
storage, and retrieval
- Improves mental functioning and ability to perform daily activities for
some people
What is the difference in MOA between cholinesterase inhibitors and
memantine (namenda)? ....... ANSWER ......- Cholinesterase inhibitors
prevent the breakdown of acetylcholine, whereas memantine (namenda)
regulates the activity of glutamate
What is ataxia? ....... ANSWER ......- Also known as cerebellum attacks
- Degenerative disease of the nervous system
- Many symptoms mimic those of being drunk (i.e. slurred speech,
stumbling, falling, and incoordination)
, What causes the symptoms of ataxia? ....... ANSWER ......- The damage
caused to the cerebellum, the part of the brain that is responsible for
coordinating movements
Page | 4 - Can also be caused by damage to part of the spinal cord and nerves
What is the treatment for ataxia? ....... ANSWER ......- No treatment
- In some cases, treating the underlying causes (i.e. stopping medications
that cause ataxia)
- In other cases, it is a result from chicken pox or other viral infections
(likely to resolve on its own)
- Genetic causes/predisposed disposition is usually chronic
What causes ataxia in the pediatric population? ....... ANSWER ......-
Genetic predisposition
- Fragile X-Associated Tremor/Ataxia Syndrome (FXTAS)
- Prader-Willie Syndrome
What is Fragile X syndrome (FXS)? ....... ANSWER ......- A genetic
condition inherited from parents which results in various developmental
problems
- Rare, but may be dangerous or life-threatening
- Present at birth and is a lifelong condition
- Rarely requires lab testing or imaging
- Often linked to autism (1/3 do have autism)
- X-linked disorder
