Subject Area NR 603 Advanced Clinical Diagnosis and Practice Across the Lifespan
Practicum
Description This comprehensive examination assesses the student's ability to synthesize
advanced pathophysiology, pharmacology, and evidence-based diagnostic
reasoning across the lifespan. It emphasizes the integration of subjective and
objective data to formulate differential diagnoses, select appropriate diagnostic
tests, and develop management plans for complex, multi-system presentations.
The exam includes screenshot-based clinical scenarios that cannot be highlighted
to mimic real-world electronic health record constraints.
Expected Grade A+
Total Questions 200
Duration 3 hours
Learning Outcomes 1. Differentiate between competing diagnoses using Bayesian reasoning and
likelihood ratios.
2. Interpret ambiguous or conflicting clinical data to avoid diagnostic errors.
3. Apply pharmacogenomic principles to individualize therapy in complex cases.
4. Integrate ethical and legal considerations in diagnostic decision-making.
Accreditation This exam meets the rigorous standards of the Commission on Collegiate Nursing
Education (CCNE) and aligns with the National Organization of Nurse
Practitioner Faculties (NONPF) core competencies.

,1. A 45-year-old patient with a history of recurrent urinary tract infections presents
with acute flank pain, fever, and hematuria. Urinalysis shows pyuria and
bacteriuria. Renal ultrasound reveals a 2-cm stone in the renal pelvis. The patient
has no known drug allergies. Which of the following is the most appropriate initial
step in management?
A. Obtain a non-contrast CT scan of the abdomen and pelvis to assess stone composition and
anatomy.
B. Initiate empiric antibiotic therapy with ciprofloxacin and schedule urgent urology
consultation for possible lithotripsy.
C. Start intravenous fluids and pain control, and obtain urine culture before initiating
antibiotics.
D. Prescribe tamsulosin to facilitate stone passage and schedule follow-up in 2 weeks.
Answer: C. Start intravenous fluids and pain control, and obtain urine culture
before initiating antibiotics.
In a patient with signs of infection and obstruction, the priority is to stabilize with fluids
and pain control, and obtain a urine culture to guide targeted antibiotics. Immediate
CT is not necessary if ultrasound already shows the stone. Empiric antibiotics without
culture may lead to resistance or miss atypical pathogens. Tamsulosin is for ureteral
stones, not for an infected obstructed renal pelvis, which requires urgent
decompression.

,2. A 30-year-old patient with a history of asthma presents with acute dyspnea,
wheezing, and a peak expiratory flow rate (PEFR) of 50% of predicted. The patient
has been using a short-acting beta-agonist (SABA) inhaler every 2 hours for the past
24 hours. Which of the following is the most appropriate next step in management?
A. Administer systemic corticosteroids and continue SABA as needed; discharge if PEFR
improves to >70%.
B. Start intravenous magnesium sulfate and arrange for immediate intubation.
C. Switch to a long-acting beta-agonist (LABA) inhaler and schedule pulmonary function
tests.
D. Increase SABA frequency to every 30 minutes and monitor for 4 hours.
Answer: A. Administer systemic corticosteroids and continue SABA as needed;
discharge if PEFR improves to >70%.
This patient has a moderate to severe acute exacerbation (PEFR 50-70%). National
guidelines recommend systemic corticosteroids (oral or IV) and frequent SABA. If
PEFR improves to >70% after initial treatment, discharge with oral steroids is
appropriate. Magnesium sulfate is reserved for severe exacerbations not responding to
initial therapy. Intubation is for impending respiratory failure. LABA is not indicated
for acute exacerbations.
3. A 55-year-old patient with type 2 diabetes, hypertension, and chronic kidney
disease (eGFR 35 mL/min/1.73m²) presents with progressive dyspnea, orthopnea,
and bilateral lower extremity edema. Blood pressure is 160/95 mmHg. Which of the
following medication adjustments is most appropriate to reduce the risk of
worsening renal function?
A. Start a loop diuretic and continue the current ACE inhibitor at the same dose.
B. Discontinue the ACE inhibitor and start an angiotensin receptor blocker (ARB) at a low
dose.
C. Add a thiazide diuretic and increase the ACE inhibitor dose.
D. Start a loop diuretic, hold the ACE inhibitor, and consider initiating a beta-blocker.
Answer: D. Start a loop diuretic, hold the ACE inhibitor, and consider initiating a
beta-blocker.
In advanced CKD with volume overload, loop diuretics are preferred to manage edema.
ACE inhibitors can cause further decline in eGFR, especially during acute illness, and
may need temporary discontinuation. Adding a beta-blocker may be beneficial for
heart failure. ARB is not safer than ACE inhibitor in this context. Thiazides are
ineffective with eGFR <30.

, 4. A 65-year-old patient with a history of atrial fibrillation on warfarin presents with
acute onset of severe right lower quadrant abdominal pain, nausea, and vomiting.
CT scan shows a thickened cecum with inflammatory changes and a focal area of
pneumatosis. INR is 4.5. Which of the following is the most likely diagnosis?
A. Acute appendicitis
B. Clostridium difficile colitis
C. Ischemic colitis
D. Diverticulitis
Answer: C. Ischemic colitis
Pneumatosis intestinalis (air in the bowel wall) in the setting of supratherapeutic INR
(4.5) and atrial fibrillation suggests ischemic colitis due to thromboembolism or
hemorrhage. Warfarin over-anticoagulation increases bleeding risk, and atrial
fibrillation predisposes to emboli. Appendicitis typically presents with periumbilical
pain migrating to RLQ, not pneumatosis. C. diff colitis usually has diarrhea and
pseudomembranes. Diverticulitis is left-sided more often.
5. A 40-year-old patient with a history of recurrent major depressive disorder
presents with acute onset of confusion, myoclonus, hyperreflexia, and fever. The
patient recently started a new medication for depression. Which of the following
medications is most likely responsible?
A. Bupropion
B. Sertraline
C. Mirtazapine
D. Tranylcypromine
Answer: D. Tranylcypromine
The triad of mental status change, autonomic instability, and neuromuscular
hyperactivity is classic for serotonin syndrome. Tranylcypromine, a monoamine oxidase
inhibitor (MAOI), can cause serotonin syndrome when combined with serotonergic
drugs or at high doses. Bupropion is not serotonergic. Sertraline alone is less likely to
cause severe serotonin syndrome unless combined with other serotonergics.
Mirtazapine has minimal serotonergic activity.
