NURS_702: Barkley Adult-Gerontology Primary
Care NP(AGCNP) Prep with Detailed Rationales
Course Code: NURS_702
Course Name: Adult-Gerontology Primary Care Nurse Practitioner
(AGPCNP) Certification Review
Topic: Comprehensive Systems Integration & Clinical Decision Bank
Academic Year: 2026/2027
1. A 74-year-old male presents for a routine wellness examination. On
cardiovascular auscultation, the nurse practitioner notes a crescendo-
decrescendo systolic murmur at the right upper sternal border that radiates
directly into the carotid arteries. The client reports mild exertional dyspnea.
Which of the following conditions is the correct diagnosis?
A. Mitral valve regurgitation
B. Aortic valve stenosis
C. Mitral valve prolapse
D. Tricuspid regurgitation
CORRECT ANSWER: B. Aortic valve stenosis
RATIONALE: Aortic stenosis is the most common valvular disease in
elderly adults, typically driven by progressive age-related calcification. The
classic murmur profile is a harsh crescendo-decrescendo systolic murmur
located at the right upper sternal border (aortic area) that radiates to the
carotids. Symptoms often develop late and present as the classic triad of
dyspnea, angina, and syncope. Mitral regurgitation is a holosystolic murmur
heard best at the apex that radiates to the axilla. Mitral valve prolapse
features a mid-systolic click. Tricuspid regurgitation is a holosystolic
murmur heard best at the lower left sternal border.
2. An 82-year-old female presents to the primary care clinic accompanied by
her daughter, who reports that her mother has become increasingly confused,
has fallen twice over the past 48 hours, and is experiencing new urinary
incontinence. The client denies dysuria. A clean-catch urinalysis reveals
positive leukocyte esterase and nitrites. Which action represents the most
appropriate initial clinical management?
, A. Refer the client to an inpatient psychiatric unit for acute dementia
evaluation.
B. Obtain a urine culture and initiate empiric oral antibiotic therapy for
an atypical urinary tract infection (UTI).
C. Order an emergent head CT scan without contrast and restrict oral fluids.
D. Prescribe a high-dose benzodiazepine to manage behavioral confusion.
CORRECT ANSWER: B. Obtain a urine culture and initiate empiric oral
antibiotic therapy for an atypical urinary tract infection (UTI).
RATIONALE: Geriatric clients frequently present with atypical
manifestations of infection. Instead of the classic symptoms of dysuria,
frequency, and fever seen in younger adults, elderly individuals with a
urinary tract infection (UTI) often present primarily with acute altered
mental status (delirium), falls, anorexia, or new-onset incontinence.
Positive nitrites and leukocyte esterase support a bacterial infection. The
proper step is to collect a culture and initiate empiric antibiotic treatment.
Psych units, head CTs, and benzodiazepines are inappropriate because they
fail to address the underlying bacterial trigger and can exacerbate delirium.
3. A 68-year-old male with a history of chronic obstructive pulmonary
disease (COPD) presents with an acute increase in dyspnea and productive
sputum changes. The nurse practitioner determines that the client is
experiencing a mild-to-moderate COPD exacerbation. Which
pharmacological agent is the first-line choice for reducing acute
bronchoconstriction?
A. Inhaled short-acting beta2-agonist (SABA) combined with a short-
acting muscarinic antagonist (SAMA).
B. Scheduled long-acting beta2-agonist (LABA) monotherapy.
C. Intravenous broad-spectrum aminoglycoside therapy.
D. High-dose oral loop diuretics.
CORRECT ANSWER: A. Inhaled short-acting beta2-agonist (SABA)
combined with a short-acting muscarinic antagonist (SAMA).
RATIONALE: The immediate pharmacological intervention for an acute
COPD exacerbation is the optimization of inhaled bronchodilator therapy
using short-acting agents such as a SABA (e.g., albuterol) combined with
a SAMA (e.g., ipratropium) via a metered-dose inhaler with a spacer or
nebulizer. Long-acting bronchodilators (LABAs/LAMAs) are maintenance
, drugs and are not fast-acting rescue medications. Aminoglycosides and loop
diuretics are not indicated for standard COPD rescue and carry toxicities for
older adults.
4. A 71-year-old female presents for the management of type 2 diabetes
mellitus. Her current hemoglobin A1c is 8.2% despite optimized metformin
therapy. The client has a documented history of atherosclerotic
cardiovascular disease (ASCVD). Which class of antidiabetic medications
should the nurse practitioner select next based on current clinical
guidelines?
A. Sulfonylureas such as glipizide
B. Thiazolidinediones such as pioglitazone
C. Glucagon-like peptide-1 (GLP-1) receptor agonists or SGLT2
inhibitors
D. Basal insulin analogs given at bedtime
CORRECT ANSWER: C. Glucagon-like peptide-1 (GLP-1) receptor
agonists or SGLT2 inhibitors
RATIONALE: For clients with type 2 diabetes mellitus and established
atherosclerotic cardiovascular disease (ASCVD), heart failure, or chronic
kidney disease, guidelines recommend adding a GLP-1 receptor agonist or
an SGLT2 inhibitor with proven cardiovascular benefit. This
recommendation applies regardless of the baseline A1c, as these drug classes
significantly lower the risk of major adverse cardiovascular events (MACE).
Sulfonylureas carry high hypoglycemia risks in older adults.
Thiazolidinediones can precipitate fluid retention and exacerbate heart
failure.
5. A 79-year-old female is diagnosed with osteoporosis following a dual-
energy X-ray absorptiometry (DEXA) scan that revealed a T-score of -2.8 in
the lumbar spine. The nurse practitioner prescribes oral alendronate. Which
administrative instruction is essential to prevent severe esophageal injury?
A. Take the medication first thing in the morning with a full glass of
plain water on an empty stomach and remain upright for at least 30
minutes before eating.
B. Take the tablet right before bedtime with a warm cup of milk or juice.
C. Crush the tablet and take it simultaneously with calcium and iron
supplements.
, D. Take the medication with a high-fat meal to optimize intestinal
absorption.
CORRECT ANSWER: A. Take the medication first thing in the morning
with a full glass of plain water on an empty stomach and remain upright
for at least 30 minutes before eating.
RATIONALE: Oral bisphosphonates like alendronate are highly
irritating to the gastrointestinal mucosa and can cause severe chemical
esophagitis or esophageal ulceration if they reflux. Clients must take the
medication first thing in the morning on an empty stomach with plain
water (not juice or milk, which inhibit absorption) and remain completely
upright for at least 30 minutes before consuming any food, beverages, or
other medications. Bedtime dosing, crushing, or taking with food/minerals
impairs efficacy and safety.
6. A 67-year-old male presents with a complaint of a new, persistent, unilateral
headache localized to the right temporal region, accompanied by jaw
discomfort while chewing food. The nurse practitioner suspects giant cell
arteritis (temporal arteritis). Which diagnostic and therapeutic plan is the
immediate priority?
A. Order an outpatient outpatient neurology consult and check an MRI of the
brain.
B. Draw a stat erythrocyte sedimentation rate (ESR) and initiate high-
dose systemic corticosteroid therapy immediately to prevent permanent
vision loss.
C. Prescribe high-dose oral NSAIDs and schedule a follow-up visit in two
weeks.
D. Reassure the client that these are normal age-related temporomandibular
joint updates.
CORRECT ANSWER: B. Draw a stat erythrocyte sedimentation rate
(ESR) and initiate high-dose systemic corticosteroid therapy
immediately to prevent permanent vision loss.
RATIONALE: Giant cell arteritis (GCA) is a systemic granulomatous
vasculitis that primarily affects medium and large arteries in older adults.
The classic presentation includes a new unilateral temporal headache, scalp
tenderness, jaw claudication, and an elevated ESR. GCA is a medical
emergency because occlusion of the ophthalmic artery can lead to
