Questions & Verified Answers
1. Which of the following is considered an Instrumental Activity of Daily Living (IADL)?
A. Bathing
B. Managing finances
C. Dressing
D. Toileting
Answer: B
Rationale: IADLs are complex skills needed to live independently, such as managing finances, cooking, and
shopping, while ADLs refer to basic self-care like bathing. Exam questions often test the ability to distinguish
this concept from closely related distractors, making a clear rationale essential for mastery. Applying this
knowledge in clinical settings supports safe, evidence-based practice and improves patient outcomes.
2. Which formula is preferred for estimating creatinine clearance in older adults for medication
dosing?
A. Friedewald equation
B. Cockcroft-Gault equation
C. Hockings formula
D. BMI index
Answer: B
Rationale: The Cockcroft-Gault equation is the standard for estimating renal function to adjust medication
dosages in the elderly. This is an important clinical concept because selecting the correct answer (B) requires
understanding both the pathophysiology and the practical nursing implications. Recognizing this principle
allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.
3. According to the Beers Criteria, which class of medication should generally be avoided in
older adults due to high risk of falls?
A. ACE inhibitors
B. Benzodiazepines
C. Statins
D. Proton pump inhibitors
Answer: B
Rationale: Benzodiazepines increase the risk of cognitive impairment, delirium, falls, and fractures in older
adults. Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide
accurate patient education. Exam questions often test the ability to distinguish this concept from closely related
distractors, making a clear rationale essential for mastery.

4. What is the hallmark clinical feature that distinguishes delirium from dementia?
A. Memory loss
B. Acute onset and fluctuating course
C. Poor judgment
D. Aphasia
Answer: B
Rationale: Delirium is characterized by an acute onset and a fluctuating course of consciousness, whereas
dementia is chronic and progressive. This is an important clinical concept because selecting the correct answer
(B) requires understanding both the pathophysiology and the practical nursing implications. Recognizing this
principle allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.
5. A patient scores 1 on the 3-word recall of the Mini-Cog and draws an abnormal clock. What is
the interpretation?
A. Normal cognition
B. Positive screen for dementia
C. Mild cognitive impairment
D. Inconclusive result
Answer: B
Rationale: A Mini-Cog score of 0 on recall, or 1-2 on recall with an abnormal clock, indicates a positive screen
for dementia. This is an important clinical concept because selecting the correct answer (B) requires
understanding both the pathophysiology and the practical nursing implications. Recognizing this principle
allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.
6. What is the most appropriate screening tool for depression specifically validated for the
elderly?
A. PHQ-9
B. Beck Depression Inventory
C. Geriatric Depression Scale (GDS)
D. Hamilton Rating Scale
Answer: C
Rationale: The GDS is a validated tool specifically designed to screen for depression in the older population,
focusing less on somatic symptoms. Exam questions often test the ability to distinguish this concept from
closely related distractors, making a clear rationale essential for mastery. Applying this knowledge in clinical
settings supports safe, evidence-based practice and improves patient outcomes.
