NURS 5434 Comprehensive Practice Test: Diagnostic
Frameworks & Rationales 2026
The NURS 5434 Family Nurse Practitioner III Exam is a comprehensive, clinically
driven evaluation designed to measure an advanced practice nursing student's
readiness to diagnose, manage, and treat complex, multi-system conditions in
primary care.
1. A 67-year-old male with a history of heart failure with reduced ejection fraction (HFrEF)
and chronic kidney disease (CKD) Stage 3b presents for a routine follow-up. His blood
pressure is 142/86 mmHg, and his potassium level is 5.2 mEq/L. He is currently taking
Lisinopril 20 mg daily and Carvedilol 12.5 mg twice daily. Which of the following is the
most appropriate next step in managing his medications?
A) Add Spironolactone 25 mg daily
B) Increase Lisinopril to 40 mg daily
C) Switch Lisinopril to Sacubitril/Valsartan (ARNI)
D) Add Amlodipine 5 mg daily
Rationale: Sacubitril/Valsartan (ARNI) is indicated to replace an ACE inhibitor or ARB in
patients with HFrEF to further reduce morbidity and mortality. Spironolactone is
contraindicated due to hyperkalemia (potassium > 5.0 mEq/L) and advanced CKD.
2. A 42-year-old female presents with a 3-month history of worsening fatigue, unintentional
weight gain of 12 pounds, constipation, and cold intolerance. Lab results reveal a TSH
of 14.2 mIU/L and a Free T4 of 0.6 ng/dL. She is diagnosed with primary
hypothyroidism and started on Levothyroxine. Which of the following patient statements
indicates a correct understanding of taking this medication?
A) "I will take my medication with breakfast and a full glass of milk."
B) "I will take it first thing in the morning on an empty stomach, at least 30 to 60
minutes before coffee or food."
C) "I should take this pill right before bedtime with my calcium supplement."
D) "I can take it at any time of the day as long as I am consistent."
Rationale: Levothyroxine absorption is maximized when taken in the morning on an
empty stomach with water, 30 to 60 minutes before food, caffeine, or other medications
(especially calcium and iron).
,3. A 74-year-old female with severe COPD (GOLD Stage 3, Group E) presents reporting
an increase in sputum volume and change in sputum color from clear to dark green over
the last 48 hours. She denies fever or shortness of breath beyond her baseline. Her
oxygen saturation is 90% on room air (her baseline). In addition to increasing her
rescue inhaler frequency, what is the first-line therapeutic intervention?
A) Order an urgent outpatient chest CT scan
B) Prescribe a 14-day course of high-dose Amoxicillin
C) Prescribe a 5-day course of oral Prednisone and an empirical antibiotic like
Azithromycin
D) Refer her immediately to the emergency department
Rationale: An acute COPD exacerbation characterized by increased sputum volume
and purulence warrants a short course of oral corticosteroids (typically 5 days) and
empirical antibiotic coverage targeting common respiratory pathogens.
4. A 28-year-old pregnant female at 26 weeks gestation presents to the clinic with a blood
pressure of 152/96 mmHg. A repeat reading 4 hours later is 154/98 mmHg. Urinalysis
reveals 1+ protein. She has no headache, visual changes, or right upper quadrant pain.
What is the most accurate initial diagnosis?
A) Gestational hypertension
B) Preeclampsia without severe features
C) Chronic essential hypertension
D) Preeclampsia with severe features
Rationale: Preeclampsia without severe features is defined as a blood pressure \(\ge \)
140/90 mmHg after 20 weeks of gestation in a previously normotensive woman,
accompanied by proteinuria, in the absence of severe symptoms (like
thrombocytopenia, impaired liver function, or severe persistent RUQ pain).
5. A 58-year-old male with a history of Type 2 Diabetes, hypertension, and an eGFR of 38
mL/min/1.73m² presents with an HbA1c of 8.2%. He is currently taking Metformin 1000
mg twice daily. According to current ADA guidelines, what is the best pharmacological
adjustment?
A) Maintain the current Metformin dose and add a Sulfonylurea
B) Discontinue Metformin immediately and start basal insulin
C) Reduce Metformin to 1000 mg daily and initiate an SGLT2 inhibitor
D) Switch Metformin to a Meglitinide
Rationale: Metformin can be safely continued if the eGFR is between 30 and 44
mL/min/1.73m², but the dose must be halved (maximum 1000 mg daily). An SGLT2
inhibitor is highly recommended for diabetic patients with CKD to slow renal decline,
provided eGFR satisfies the specific drug's starting threshold.
6. An 82-year-old resident of an assisted living facility is brought to the clinic by staff who
report that he has become acutely confused, agitated, and has experienced two falls in
the last 24 hours. He denies dysuria, chest pain, or cough. Vital signs show a
temperature of 37.6°C (99.7°F), pulse 92 bpm, and blood pressure 110/68 mmHg. What
diagnostic study is the highest priority?
A) Non-contrast head CT scan
B) Urinalysis with reflex culture
C) 12-lead Electrocardiogram (ECG)
D) Serum Troponin level
, Rationale: In geriatric patients, acute delirium, agitation, and falls are common atypical
presentations of an acute Urinary Tract Infection (UTI) or other systemic infections,
making urinalysis the most critical initial diagnostic screening.
7. A 35-year-old female presents with severe, unilateral, throbbing head pain that lasts for
12 to 24 hours. It is accompanied by extreme photophobia and nausea. She
experiences a visual "shimmering blind spot" 20 minutes before the head pain begins.
She requests a rescue medication. She has a medical history of poorly controlled
hypertension and Raynaud's phenomenon. Which medication is strictly contraindicated?
A) Metoclopramide
B) Acetaminophen
C) Sumatriptan
D) Naproxen sodium
Rationale: Triptans (5-HT1 receptor agonists) cause vasoconstriction and are strictly
contraindicated in patients with ischemic heart disease, peripheral vascular disease,
Raynaud's phenomenon, and uncontrolled hypertension.
8. A 51-year-old female returns to the clinic to review laboratory results from her annual
physical exam. Her lipid panel reveals: Total Cholesterol 240 mg/dL, HDL 42 mg/dL,
Triglycerides 550 mg/dL, and LDL cannot be calculated. What is the primary clinical
priority when treating this lipid profile?
A) Initiate high-intensity Atorvastatin to reduce cardiovascular risk
B) Prescribe Ezetimibe to lower intestinal cholesterol absorption
C) Prescribe a Fibrinate or high-dose Omega-3 fatty acid to prevent acute
pancreatitis
D) Advise a strict low-carbohydrate diet and recheck in 6 months
Rationale: When fasting triglycerides exceed 500 mg/dL, the primary immediate clinical
focus is to lower triglycerides using fibrates or fish oils to reduce the high risk of
developing acute, life-threatening pancreatitis.
9. A 14-year-old adolescent female presents with a harsh, barking cough, inspiratory
stridor at rest, and mild intercostal retractions. Her mother states the symptoms started
suddenly last night following a mild cold. What is the most appropriate first-line
treatment for this patient in a primary care setting?
A) Oral Albuterol syrup
B) Oral Dexamethasone and immediate evaluation for nebulized epinephrine
C) Empirical Azithromycin therapy
D) Saline nasal spray and home humidified air instructions
Rationale: Stridor at rest indicates moderate-to-severe croup (laryngotracheobronchitis).
The standard of care is a single dose of systemic corticosteroid (Dexamethasone) and
nebulized racemic epinephrine to quickly reduce airway edema.
10. A 63-year-old male presents with worsening tremor, rigidity, and bradykinesia. He is
diagnosed with Parkinson's disease and started on Carbidopa/Levodopa. Several
months later, he reports that his symptoms return about an hour before his next
scheduled dose. What is the pharmacological term for this phenomenon, and what is a
potential solution?
A) Akathisia; stop the medication immediately
B) "Wearing-off" effect; increase the dosing frequency or add a COMT inhibitor
C) Tachyphylaxis; double the morning dose
, D) Dopamine dysregulation; switch to an anticholinergic
Rationale: The "wearing-off" effect happens as Parkinson's disease progresses and the
therapeutic window narrows. It is managed by shortening the dosing interval, utilizing
extended-release forms, or adding adjunctive medications like Entacapone.
11. A 45-year-old male with a history of alcohol use disorder presents with acute, severe
epigastric pain that radiates straight to his back, accompanied by persistent vomiting.
On physical exam, he is tachycardic and has marked epigastric tenderness with
guarding. Which diagnostic laboratory findings are most specific for the suspected
diagnosis?
A) Elevated Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST)
B) Elevated Serum Bilirubin and Alkaline Phosphatase
C) Elevated Serum Lipase and Amylase
D) Decreased Serum Albumin and prolonged Prothrombin Time
Rationale: Acute pancreatitis presents with severe epigastric pain radiating to the back.
Serum lipase is highly sensitive and specific, remaining elevated longer than amylase.
12. A 31-year-old female presents to the clinic with complaints of severe pelvic pain, deep
dyspareunia, and painful, heavy menstrual cycles (dysmenorrhea). She has been trying
to conceive for 18 months without success. On bimanual exam, the clinician notes a
fixed, retroverted uterus and tender nodularities along the uterosacral ligaments. What
is the gold standard for a definitive diagnosis?
A) Transvaginal Ultrasound
B) Pelvic MRI
C) Serum CA-125 measurement
D) Laparoscopy with biopsy
Rationale: While transvaginal ultrasound or MRI can suggest the presence of
endometriosis, direct visualization via exploratory laparoscopy accompanied by
histological biopsy is the definitive gold standard for diagnosis.
13. A 69-year-old male presents for a regular evaluation of his Chronic Kidney Disease
(CKD) Stage 4. His routine laboratory results demonstrate an eGFR of 22
mL/min/1.73m², Hemoglobin of 9.4 g/dL, and Ferritin of 250 ng/mL. He reports
significant generalized fatigue but denies active bleeding. What is the underlying
pathophysiology of his anemia?
A) Acute occult gastrointestinal blood loss
B) Decreased renal production of erythropoietin
C) Severe dietary vitamin B12 deficiency
D) Nutritional iron deficiency anemia
Rationale: Anemia of chronic kidney disease is primarily caused by the failing kidneys'
inability to synthesize adequate amounts of erythropoietin, the essential hormone that
stimulates red blood cell production in the bone marrow.
14. A 24-year-old male presents with a painful, swollen, and red right knee joint. He also
reports painful urination (dysuria) and conjunctivitis in his left eye. He mentions having a
severe diarrheal illness 3 weeks ago after eating at a local food truck. What is the most
likely diagnosis?
A) Septic arthritis
B) Rheumatoid arthritis
C) Reactive arthritis
