Adult-Gerontology Clinical Nurse Specialist (AGCNS-BC) — Questions and Answers

Question 1: On auscultation, a harsh systolic ejection murmur radiating to the carotids in an older adult most suggests:

Ventricular septal defect
Mitral regurgitation
Pulmonary stenosis
Aortic stenosis (Correct answer)

Correct answer: Aortic stenosis

Aortic stenosis produces a harsh crescendo-decrescendo systolic murmur at the right upper sternal border that radiates to the carotid arteries due to high-velocity turbulent flow.

Question 2: The CURB-65 score is used in pneumonia to determine:

Oxygen delivery method
Antibiotic choice and duration
Disease severity and need for hospital admission (Correct answer)
Causative organism identification

Correct answer: Disease severity and need for hospital admission

CURB-65 scores confusion, urea, respiratory rate, blood pressure, and age ≥65 to stratify pneumonia severity and guide inpatient versus outpatient management decisions.

Question 3: Presbycusis (age-related hearing loss) most commonly affects:

High-frequency sounds first due to progressive sensory hair cell loss at the cochlear base (Correct answer)
Balance more than auditory perception
Conductive hearing before sensorineural loss
Low-frequency sounds first due to cochlear base damage

Correct answer: High-frequency sounds first due to progressive sensory hair cell loss at the cochlear base

Sensory presbycusis begins with high-frequency loss because the basal cochlea processes high frequencies and experiences the greatest cumulative noise and vascular damage over time.

Question 4: A patient with terminal cancer has a signed DNR order. Which ethical principle is most directly upheld by honoring this order?

Non-maleficence
Autonomy (Correct answer)

An S3 results from rapid ventricular filling against a stiff, dilated, or volume-overloaded ventricle and is a classic physical finding in heart failure.

Question 61: A 75-year-old patient has a BMI of 17.5. How should the CNS classify this nutritional status?

Obese
Underweight (Correct answer)
Overweight
Normal weight

Correct answer: Underweight

A BMI below 18.5 is classified as underweight, indicating potential malnutrition, which is a significant concern in older adults.

Question 62: Metered-dose inhaler (MDI) technique in older adults is frequently suboptimal because:

Older adults have increased lung compliance reducing drug deposition
Coordination difficulties, arthritis, and cognitive impairment reduce proper actuation-inhalation synchrony (Correct answer)
MDIs deliver too high a drug concentration for older lungs
Older patients metabolize inhaled drugs faster

Correct answer: Coordination difficulties, arthritis, and cognitive impairment reduce proper actuation-inhalation synchrony

Effective MDI use requires coordination of breath and actuation, which is impaired by arthritis, cognitive decline, and reduced inspiratory flow in older adults.

Question 63: Interprofessional collaboration in the CNS role is important because:

Team-based care increases costs without improving quality metrics
CNSs should practice independently without team input to demonstrate advanced practice competency
Complex patient problems require the combined expertise of physicians, nurses, pharmacists, social workers, and other disciplines to optimize outcomes (Correct answer)
CNSs serve primarily as physician extenders without distinct advanced practice contributions

Correct answer: Complex patient problems require the combined expertise of physicians, nurses, pharmacists, social workers, and other disciplines to optimize outcomes

Correct answer: Prolongs the QTc interval, increasing risk of torsades de pointes

Azithromycin prolongs cardiac repolarization (QTc prolongation), particularly dangerous in older adults with structural heart disease or those on other QT-prolonging agents.

Question 152: A CNS is caring for an 82-year-old on long-term corticosteroids. Which prophylactic medication is most important to add?

Anticoagulant
Antifungal
Proton pump inhibitor
Bisphosphonate (Correct answer)

Correct answer: Bisphosphonate

Long-term corticosteroids cause bone loss; bisphosphonates are recommended to prevent glucocorticoid-induced osteoporosis.

Question 153: Clinical benchmarking in quality improvement involves comparing:

Nursing satisfaction scores with physician satisfaction only
Cost data between competing hospitals without clinical adjustment
A single patient's outcomes over time only
Current performance metrics against external standards, national databases, or high-performing organizations (Correct answer)

Correct answer: Current performance metrics against external standards, national databases, or high-performing organizations

Benchmarking compares an organization's outcomes (e.g., infection rates, readmissions) against national databases like NDNQI or peer hospitals to identify performance gaps and improvement targets.

Question 154: Hand hygiene compliance is the single most effective measure to prevent:

Medication administration errors
Healthcare-associated infections including CLABSI, CAUTI, SSI, and C. difficile transmission (Correct answer)
Ventilator-associated pneumonia alone
Patient falls in the hospital setting

Correct answer: Healthcare-associated infections including CLABSI, CAUTI, SSI, and C. difficile transmission

Contaminated healthcare worker hands are the primary vector for most healthcare-associated infections; consistent hand hygiene before and after patient contact interrupts transmission across all infection types.

Question 155: Which medication reduces the rate of COPD exacerbations when added to a long-acting bronchodilator regimen?

Short-acting beta agonists
Oral theophylline
Systemic corticosteroids
Inhaled corticosteroids (Correct answer)

Correct answer: Inhaled corticosteroids

Inhaled corticosteroids added to LABA therapy reduce exacerbation frequency in COPD patients with frequent flare-ups.

Question 156: Age-related immune senescence increases older adults' susceptibility to infection through:

Reduced naive T-cell production, impaired antibody response, and chronic low-grade inflammation (inflammaging) (Correct answer)
Overactive complement system causing excessive inflammation
Increased B-cell and T-cell proliferation causing autoimmune disease
Enhanced natural killer cell function paradoxically causing tissue damage

Correct answer: Reduced naive T-cell production, impaired antibody response, and chronic low-grade inflammation (inflammaging)

Immune senescence reduces thymic output of naive T cells, impairs vaccine responses, and creates baseline chronic inflammation (inflammaging) that paradoxically reduces pathogen-specific immunity.

Question 157: Which statistical measure best conveys the clinical significance of a treatment effect in practice?

Number needed to treat (NNT) (Correct answer)
Relative risk
Standard deviation
P-value

Correct answer: Number needed to treat (NNT)

NNT conveys how many patients must be treated to prevent one additional adverse outcome, making it clinically meaningful and actionable.

Question 158: A patient with COPD uses a short-acting bronchodilator more than twice a week. What does this indicate?

Normal rescue medication use
Uncontrolled symptoms requiring therapy adjustment (Correct answer)
Well-controlled disease
Need for oral corticosteroids immediately

Correct answer: Uncontrolled symptoms requiring therapy adjustment

Using rescue bronchodilators more than twice weekly signals inadequate COPD symptom control and warrants reassessment of the maintenance regimen.

Question 159: Post-operative cognitive dysfunction (POCD) in older adults differs from delirium in that POCD:

Is a persistent subtle cognitive decline lasting weeks to months after surgery, without acute fluctuation (Correct answer)
Occurs only intraoperatively during anesthesia administration
Only affects patients with pre-existing dementia
Is exclusively caused by general anesthesia and not regional techniques

Correct answer: Is a persistent subtle cognitive decline lasting weeks to months after surgery, without acute fluctuation

POCD is characterized by subtle, persistent cognitive decline detectable on neuropsychological testing that can persist months after surgery, unlike delirium which is acute and fluctuating.

Question 160: Proton pump inhibitors (PPIs) used long-term in older adults are associated with increased risk of:

Peptic ulcer disease recurrence
Hepatotoxicity and elevated liver enzymes
Hyperkalemia and metabolic alkalosis
Hypomagnesemia, C. difficile infection, community-acquired pneumonia, and fracture risk (Correct answer)

Correct answer: Hypomagnesemia, C. difficile infection, community-acquired pneumonia, and fracture risk

Long-term PPI use is linked to hypomagnesemia, impaired calcium absorption increasing fracture risk, C. diff susceptibility, and altered gastric microbiome predisposing to pneumonia.

Question 161: When a CNS identifies a gap between current nursing practice and best evidence, the most appropriate first step is:

Conducting a formal practice gap analysis to understand the scope, causes, and barriers before planning interventions (Correct answer)
Immediately disciplining nurses who are not following the evidence
Presenting data to administration and waiting for top-down mandate
Writing a new policy without staff input

Correct answer: Conducting a formal practice gap analysis to understand the scope, causes, and barriers before planning interventions

Understanding the root causes and scope of a practice gap through structured analysis ensures that interventions address actual barriers (education, resources, workflow) rather than assumed ones.

Question 162: What is the primary goal of translational research as it applies to nursing practice?

To conduct animal model studies for drug approval
To apply scientific findings to improve patient care outcomes (Correct answer)
To increase nursing compensation and staffing ratios
To generate basic science theories in the laboratory

Correct answer: To apply scientific findings to improve patient care outcomes

Translational research bridges the gap between scientific discovery and clinical practice to directly improve patient outcomes.

Question 163: Advance care planning discussions with older adults should focus primarily on:

Ensuring all patients choose comfort-focused care
Selecting a surrogate decision-maker only after cognitive decline
Completing legal documents without individualized discussion
Eliciting personal values, goals, and preferences to guide future medical decisions when the patient may lose decision-making capacity (Correct answer)

Correct answer: Eliciting personal values, goals, and preferences to guide future medical decisions when the patient may lose decision-making capacity

Effective advance care planning centers on understanding patient values and goals so that medical decisions align with what matters most to the individual across changing health circumstances.

Question 164: A CNS caring for a patient with chronic heart failure notes a 3-pound weight gain in 24 hours. What is the priority action?

Schedule a cardiology appointment in 1 week
Assess for fluid overload and notify the provider (Correct answer)
Encourage increased fluid intake
Order a stat ECG

Correct answer: Assess for fluid overload and notify the provider

Rapid weight gain in heart failure indicates fluid retention; immediate assessment for decompensation and provider notification are required.

Question 165: What is the primary goal of palliative care for an adult-gerontology patient with a serious illness?

Relieve suffering and improve quality of life (Correct answer)
Transition the patient to hospice immediately
Prolong life at all costs
Cure the underlying disease

Correct answer: Relieve suffering and improve quality of life

Palliative care focuses on relieving suffering and improving quality of life for patients and families facing serious illness, regardless of prognosis or curative treatment status.

Question 166: A 70-year-old with atrial fibrillation and a CHA2DS2-VASc score of 3 should receive which therapy?

No antithrombotic therapy
Aspirin alone
Dual antiplatelet therapy
Anticoagulation therapy (Correct answer)

Correct answer: Anticoagulation therapy

A CHA2DS2-VASc score of 2 or more in males or 3 or more in females indicates high stroke risk warranting anticoagulation in atrial fibrillation.

Question 167: Medication reconciliation is critical at care transitions in older adults primarily to prevent:

Pharmacy dispensing delays
Duplicate laboratory testing
Insurance billing errors from formulary changes
Medication discrepancies, omission errors, and adverse drug events during handoffs (Correct answer)

Correct answer: Medication discrepancies, omission errors, and adverse drug events during handoffs

Care transitions are high-risk periods where medications are frequently omitted, duplicated, or incorrectly transcribed, leading to preventable adverse drug events.

Question 168: The comprehensive geriatric assessment (CGA) is distinguished from standard medical assessment by:

Using only standardized questionnaires without physical examination
Being performed only by geriatricians in inpatient settings
Evaluating functional status, cognition, mood, social support, and medical issues in an interdisciplinary format (Correct answer)
Focusing exclusively on medical diagnoses and laboratory results

Correct answer: Evaluating functional status, cognition, mood, social support, and medical issues in an interdisciplinary format

CGA evaluates the whole older patient across physical, functional, cognitive, social, and environmental domains using an interdisciplinary team to develop individualized care plans.

Question 169: The regulatory body that sets standards for CNS certification in adult-gerontology is:

American Geriatrics Society (AGS)
American Nurses Association (ANA)
American Association of Critical-Care Nurses Certification Corporation (AACN Certification) or American Nurses Credentialing Center (ANCC) (Correct answer)
National Council of State Boards of Nursing (NCSBN)

Correct answer: American Association of Critical-Care Nurses Certification Corporation (AACN Certification) or American Nurses Credentialing Center (ANCC)

ANCC offers the Adult-Gerontology CNS (AGCNS-BC) and AACN Certification Corporation offers CCNS for acute/critical care CNS, both requiring graduate education, clinical hours, and passing a competency examination.

Question 170: A CNS manages a patient with newly diagnosed type 2 diabetes and HbA1c of 8.5%. What is the recommended first-line oral medication?

Pioglitazone
Glipizide
Metformin (Correct answer)
Sitagliptin

Correct answer: Metformin

Metformin remains the preferred first-line oral agent for type 2 diabetes unless contraindicated due to its safety, efficacy, and cost profile.

Question 171: The Adult-Gerontology CNS should prioritize which assessment when an older patient presents with acute confusion?

Nutritional screening
Chronic pain evaluation
Delirium assessment using the CAM (Correct answer)
Depression screening

Correct answer: Delirium assessment using the CAM

The Confusion Assessment Method (CAM) is the gold-standard tool for diagnosing delirium in hospitalized older adults.

Question 172: The principle of "start low and go slow" in prescribing for older adults reflects which age-related pharmacokinetic change?

Decreased hepatic and renal drug clearance causing drug accumulation at standard doses (Correct answer)
Faster GI absorption increasing peak drug levels
Increased plasma protein binding reducing free drug
Increased receptor sensitivity requiring higher doses

Correct answer: Decreased hepatic and renal drug clearance causing drug accumulation at standard doses

Reduced hepatic metabolism and renal excretion prolong drug half-lives in older adults, making standard doses more likely to accumulate to toxic levels.

Question 173: The Physician Orders for Life-Sustaining Treatment (POLST) form is best described as:

A legal document designating a healthcare proxy
A patient's written statement of general values and goals
A billing document for hospice services
A set of actionable medical orders regarding CPR, hospitalization, and artificial nutrition (Correct answer)

Correct answer: A set of actionable medical orders regarding CPR, hospitalization, and artificial nutrition

POLST is a medical order signed by a physician that translates a patient's end-of-life preferences into specific, immediately actionable orders regarding CPR, level of medical intervention, and artificial nutrition.

Question 174: Systolic hypertension in older adults is largely attributed to:

Elevated renin-angiotensin activity
Arterial stiffening and decreased aortic compliance (Correct answer)
Increased cardiac output
Increased plasma volume

Correct answer: Arterial stiffening and decreased aortic compliance

Age-related loss of arterial elasticity increases pulse wave velocity and systolic pressure while diastolic pressure may remain stable or decrease.

Question 175: Hepatic encephalopathy in cirrhosis is primarily driven by:

Hepatic arterial thrombosis
Bile salt toxicity to neurons
Accumulation of ammonia and other neurotoxins due to impaired hepatic detoxification and portosystemic shunting (Correct answer)
Hypoalbuminemia causing cerebral edema

Correct answer: Accumulation of ammonia and other neurotoxins due to impaired hepatic detoxification and portosystemic shunting

Portal hypertension creates shunts that bypass hepatic detoxification, allowing gut-derived ammonia and neurotoxins to accumulate in the systemic circulation and brain.
