NURS 504 Exam #1 Questions With Complete Solutions
A 72-year-old man with pain issues is being given a drug by the
intramuscular route. His serum blood level concentrations have
been erratic. The nurse suspects that this may be due to
decreased blood flow to tissues and muscles
When a drug is discontinued, what percentage of that drug will
remain in the body after three half-lives?
12.5%
The nurse caring for an elderly client and notes an increased
sensitivity to Xanax when comparing the results with other
adults. What normal age-related change may account for this
change in sensitivity to Xanax?
decreased effectiveness of the blood-brain barrier
Mental dysfunction in an older adult may seem like a normal
part of aging, but it can result from disease or another cause.
What should the ER staff do first for a presenting older adult
with a mental dysfunction such as extreme confusion?
Review the drugs being taken
A client has been brought to the emergency department (ED)
following a cold water incident. Which would be a potential
effect of medication absorption from this clinical manifestation?
less than therapeutic effect
,The nurse is administering medications and knows that there is a
longer distribution time when the drug is intended for what area?
skin
The nurse understands that the dosage recommended by drug
manufacturers is based on an individual weighing:
150 lb (68 kg)
The nurse knows that the pharmaceutic phase of drug activity
must take place for which formulation of medication?
oral tablets
The nurse is preparing to give an older adult client an IM
injection. How will this client's history of heart failure affect the
administration of this medication?
- abnormal blood concentrations of the medication
- decreased absorption of the medication
A client has not experienced the desired therapeutic effects of a
medication. When considering factors that may affect the
dynamic equilibrium that influences drug concentration, the
nurse should:
assess for factors that may reduce absorption
What does the nurse need to do when there is any indication of
an allergic reaction in clients?
Maintain the client's safety during drug therapy
A 76-year-old client with congestive heart failure is being
admitted to the hospital. The client states only taking
,medications that the health care provider prescribes, but when
the nurse assesses the medications, three over-the-counter
laxatives are in the client's bag of medications. What concerns

As a result of age-related changes, older adults face an increased
risk of adverse medication effects
What is the most frequently used drug administration route in

With buccal medications, what factor affects absorption?

What is the relation between the activity level of older adults
and the response to medication?
The older adult who is more physically active is less likely to
have an adverse drug effect
A nurse is reading an article that describes predictable
differences in the effects of drugs in people of particular culture
backgrounds due to their genetic makeup. The nurse is reading
about:
pharmacogenomics
, Which process occurs between the time the drug enters the body
and the time that it enters the bloodstream?
absorption
Which site is preferred when consideration must be made to
identify an exceptionally large surface area for drug absorption?
lungs
Drug evaluation studies are used to determine critical
concentration. The nurse understands that the critical
concentration is the amount of the drug needed to cause:
therapeutic effect
A nurse has looked up a new drug in a drug guide and is
reviewing characteristics of its absorption. Which processes may
be involved in this drug's absorption?
- passive diffusion
- active transport
- filtration
A client has developed a tolerance to a drug. How should the
nurse address this when providing care?
Assess whether the client needs larger doses to achieve the
effect
A nurse has been administering a drug to a client
intramuscularly (IM). The health care provider discontinued the
IM dose and wrote an order for the drug to be given orally. The
nurse notices that the oral dosage is considerably higher than the
