weak areas to focus additional review time
QUESTION 1
An 78-year-old client with hypertension reports that they often forget to take
their daily medications. What is the best nursing intervention to promote
medication adherence in this older adult?
A) Tell the client that it is their responsibility and they should try harder to
remember
B) Simplify the medication regimen by working with the healthcare provider to
reduce the number of daily doses
C) Instruct the family member to administer all medications without the client's
involvement
D) Suggest the client write the medication names on their hand as a reminder
E) Recommend the client take all medications at once in the morning regardless of
timing
, CORRECT ANSWER: B) Simplify the medication regimen by working with
the healthcare provider to reduce the number of daily doses
RATIONALE: Cognitive changes and memory decline are normal aging processes.
Simplifying medication regimens by reducing the frequency of doses or combining
medications can significantly improve adherence. Complex medication schedules
with multiple daily doses are a major barrier to compliance in older adults. The
nurse should collaborate with the healthcare team to explore options like
extended-release formulations or once-daily medications. While reminders (Option
A) and family support are helpful, the most effective intervention addresses the
root cause—cognitive demands of complex regimens.
QUESTION 2
A 72-year-old client experiences decreased skin turgor and reports dry mouth.
The nurse recognizes these as signs of dehydration. What physiological
change of aging contributes most to the increased risk of dehydration in older
adults?
A) Increased thirst mechanism and heightened kidney function
B) Decreased total body water content and diminished thirst sensation
C) Excessive production of antidiuretic hormone (ADH)
D) Increased ability to concentrate urine
E) Enhanced cellular fluid retention mechanisms
CORRECT ANSWER: B) Decreased total body water content and diminished
thirst sensation
RATIONALE: Normal aging involves a decrease in total body water content from
approximately 60% in young adults to 50% in older adults. Additionally, the thirst
mechanism becomes less responsive with age, meaning older adults may not feel
thirsty until significant fluid loss has occurred. These changes place older adults at
higher risk for dehydration, especially during illness or hot weather. The decreased
,thirst sensation is particularly problematic because it removes a critical warning
sign for fluid depletion. Options A, C, D, and E describe incorrect physiological
changes that do not occur with normal aging.
QUESTION 3
An 81-year-old client with a 10-year history of diabetes mellitus type 2 is at
risk for several age-related complications. Which complication is MOST
commonly associated with both advanced age and prolonged diabetes?
A) Hyperthyroidism and increased metabolic rate
B) Peripheral neuropathy and increased risk of foot ulcers
C) Decreased blood glucose levels requiring less insulin
D) Improved renal function and better medication clearance
E) Increased bone density and stronger skeletal structure
CORRECT ANSWER: B) Peripheral neuropathy and increased risk of foot
ulcers
RATIONALE: Prolonged diabetes combined with advanced age significantly
increases the risk of peripheral neuropathy due to chronic hyperglycemia and
microvascular changes. This neuropathy reduces sensation in the feet, making
older adults with diabetes vulnerable to undetected injuries and subsequent foot
ulcers—a leading cause of lower limb amputation in this population. Aging also
slows wound healing, further complicating ulcer management. The nurse must
implement comprehensive foot care education and frequent assessments. Options
A, C, D, and E describe incorrect pathophysiological relationships with diabetes and
aging.
QUESTION 4
, A 76-year-old female client reports difficulty sleeping through the night. The
nurse understands that which of the following is a NORMAL age-related
change affecting sleep in older adults?
A) Increased production of melatonin and deeper REM sleep stages
B) Decreased time spent in deep sleep (Stage 3 NREM) with more frequent
nighttime awakenings
C) Complete elimination of REM sleep and consolidation of sleep architecture
D) Increased sleep duration to 10+ hours nightly with enhanced quality
E) Rapid onset of sleep within seconds of lying down
CORRECT ANSWER: B) Decreased time spent in deep sleep (Stage 3 NREM)
with more frequent nighttime awakenings
RATIONALE: Age-related sleep changes include decreased slow-wave (deep) sleep,
more frequent arousals and awakenings, and increased time spent in lighter sleep
stages. Older adults often experience fragmented sleep with multiple nighttime
awakenings, resulting in daytime fatigue despite spending adequate time in bed.
Melatonin production actually decreases with age, not increases. The nurse should
educate clients about normal aging changes, recommend sleep hygiene measures,
and assess for treatable causes like sleep apnea, medication side effects, or medical
conditions. Options A, C, D, and E describe incorrect sleep changes.
QUESTION 5
An 85-year-old client newly admitted to a long-term care facility frequently
calls for the nurse and reports feeling lonely and isolated. Which nursing
intervention is MOST effective in promoting psychosocial well-being in this
older adult?
A) Assign the client to a private room to minimize disruptions
