Nursing Mastery
About This Resource
This third test bank provides 100 additional clinical application questions focusing on high-stakes scenarios, diagnostic reasoning, and
pharmacologic decision-making for the APEA 3P exam . Each question includes the verified correct answer and a detailed clinical
rationale aligned with 2025/2026 evidence-based practice standards.
Advanced Physical Assessment & Differential Diagnosis
Question 1: A 58-year-old male with type 2 diabetes mellitus reports burning foot pain that worsens at night. Examination reveals diminished
pinprick sensation distal to the ankles and absent Achilles reflexes bilaterally. What is the most likely diagnosis?
A) Peripheral artery disease
B) Lumbar radiculopathy
C) Diabetic peripheral neuropathy
D) Vitamin B12 deficiency
Correct Answer: C) Diabetic peripheral neuropathy
Rationale: Distal symmetric polyneuropathy is the most common complication of diabetes, presenting with burning pain, nocturnal
exacerbation, distal sensory loss ("stocking-glove" distribution), and areflexia. PAD causes claudication (cramping with exercise), not burning
dysesthesias. Lumbar radiculopathy follows a dermatomal pattern, not symmetric distal distribution .
Question 2: A 45-year-old woman has blood pressure readings of 152/96 mmHg and 150/94 mmHg on two separate office visits. She has no
known comorbidities or target organ damage. According to current hypertension guidelines, what is the appropriate first step?
A) Start amlodipine 5 mg daily
B) Start lisinopril 10 mg daily
C) Recommend DASH diet and exercise for 4-6 months
D) Order renal artery duplex ultrasound
Correct Answer: C) Recommend DASH diet and exercise for 4-6 months
Rationale: For Stage 2 hypertension (SBP 140-159 or DBP 90-99) without comorbidities or target organ damage, current guidelines recommend
therapeutic lifestyle changes (DASH diet, sodium restriction, exercise, weight loss) for 4-6 months before initiating pharmacotherapy.
Pharmacologic treatment is initiated immediately if comorbidities or target organ damage are present .
Question 3: A 32-year-old man presents with sudden onset of severe, tearing chest pain that radiates to the back. Blood pressure is 160/90
mmHg in the right arm and 100/60 mmHg in the left arm. ECG shows no ST-segment elevation. What is the most likely diagnosis?
A) Acute myocardial infarction
B) Pulmonary embolism
C) Aortic dissection
D) Acute pericarditis
Correct Answer: C) Aortic dissection
Rationale: Aortic dissection classically presents with "tearing" chest pain that radiates to the back, associated with asymmetric blood pressures
between arms (difference >20 mmHg systolic). This is a surgical emergency requiring immediate CT angiography and vascular surgery
consultation. The asymmetric pulses result from dissection extending into the subclavian artery .
,Question 4: A 70-year-old woman reports progressive forgetfulness over the past two years. Examination reveals difficulty with word finding,
apraxia (inability to perform learned movements), and agnosia (inability to recognize objects). MMSE score is 22/30. Cognition does not
fluctuate significantly. What is the most likely diagnosis?
A) Alzheimer's disease
B) Lewy body dementia
C) Frontotemporal dementia
D) Vascular dementia
Correct Answer: A) Alzheimer's disease
Rationale: Alzheimer's disease presents with gradual onset of memory loss followed by other cortical signs (aphasia, apraxia, agnosia). The lack
of fluctuation distinguishes it from Lewy body dementia. The absence of early behavioral changes argues against frontotemporal dementia. The
insidious onset without stepwise decline argues against vascular dementia .
Question 5: A 68-year-old woman with osteoporosis has been taking alendronate for five years. She now reports severe thigh and groin pain. X-
ray of the femur demonstrates transverse cortical thickening on the lateral aspect. What is the most likely diagnosis?
A) Osteosarcoma
B) Atypical femoral fracture precursor
C) Paget's disease of bone
D) Osteomalacia
Correct Answer: B) Atypical femoral fracture precursor
Rationale: Bisphosphonates (alendronate) are associated with atypical femoral fractures. Prodromal thigh or groin pain with radiographic
findings of cortical beaking or thickening ("dreaded black line") indicates impending atypical fracture. The bisphosphonate should be
discontinued, and orthopedic referral is urgent .
Question 6: A 42-year-old man presents with episodic, unilateral, severe pulsatile headache accompanied by tearing of the eye, rhinorrhea, and
restlessness. Each episode lasts 30-60 minutes and occurs at the same time of day. What is the most appropriate acute treatment?
A) Sumatriptan 6 mg subcutaneous
B) Naproxen 500 mg oral
C) Oxygen 15 L/min via non-rebreather mask
D) Ergotamine 2 mg sublingual
Correct Answer: C) Oxygen 15 L/min via non-rebreather mask
Rationale: This is cluster headache. High-flow oxygen (100% at 12-15 L/min via non-rebreather) is first-line acute treatment, highly effective and
safe. Subcutaneous sumatriptan is also effective but has more contraindications. Oxygen is preferred as initial therapy due to rapid onset and
excellent safety profile .
Question 7: A 50-year-old woman with a 20-pack-year smoking history presents with dyspnea on exertion, chronic cough, and wheezing.
Spirometry reveals FEV1/FVC ratio of 65% (predicted 80%) with FEV1 55% of predicted. What is the most appropriate classification of this
patient's COPD?
A) GOLD Stage 1 (Mild)
B) GOLD Stage 2 (Moderate)
C) GOLD Stage 3 (Severe)
D) GOLD Stage 4 (Very Severe)
Correct Answer: C) GOLD Stage 3 (Severe)
Rationale: GOLD COPD classification uses post-bronchodilator FEV1 % predicted: GOLD 1: ≥80%, GOLD 2: 50-79%, GOLD 3: 30-49%, GOLD 4:
<30%. With FEV1 55% of predicted, this patient meets criteria for GOLD Stage 2 (Moderate). The FEV1/FVC ratio <70% confirms obstruction.
Question 8: A 28-year-old woman presents with acute onset of right lower quadrant pain, nausea, and anorexia. On examination, tenderness is
elicited at McBurney's point with rebound tenderness. What is the most appropriate next step?
, A) Discharge home with oral antibiotics
B) Immediate surgical consultation
C) Order pelvic ultrasound before surgical consult
D) Prescribe antiemetics and observe for 24 hours
Correct Answer: B) Immediate surgical consultation
Rationale: McBurney's point tenderness with nausea, anorexia, and rebound tenderness is classic for acute appendicitis. Surgical consultation
should not be delayed for imaging when clinical suspicion is high, as perforation risk increases with time. Imaging (CT or ultrasound) may be
obtained but should not delay surgical evaluation.
Question 9: A 55-year-old man presents with acute onset of sharp pleuritic chest pain and dyspnea following a 10-hour international flight. He
has a history of DVT. Vital signs: HR 110, RR 24, O2 saturation 90% on room air. What is the most appropriate initial diagnostic test?
A) Chest X-ray
B) D-dimer
C) CT pulmonary angiography
D) Ventilation-perfusion scan
Correct Answer: C) CT pulmonary angiography
Rationale: This patient has high pretest probability for pulmonary embolism (recent travel, prior DVT, tachycardia, hypoxia). CTPA is the
diagnostic test of choice in high-probability patients. D-dimer has poor specificity in high-probability patients and should not delay definitive
imaging. Chest X-ray is non-diagnostic for PE.
Question 10: On fundoscopic examination, the NP notes copper-wiring of arterioles and arteriovenous nicking. What is the most likely
underlying condition?
A) Diabetic retinopathy
B) Hypertensive retinopathy
C) Optic neuritis
D) Glaucoma
Correct Answer: B) Hypertensive retinopathy
Rationale: Copper-wiring (increased light reflex from thickened arteriolar walls) and arteriovenous nicking (compression of veins at
arteriovenous crossings) are hallmark findings of chronic hypertensive retinopathy. These changes indicate arteriolosclerosis from longstanding
hypertension.
Advanced Pharmacology & Pharmacotherapeutics
Question 11: A 22-year-old woman presents with palpitations, anxiety, heat intolerance, and diarrhea. Examination reveals diffuse goiter,
exophthalmos, and pretibial myxedema. Laboratory studies show TSH <0.01 mIU/L and free T4 >5.0 ng/dL. What is the most appropriate
definitive treatment?
A) Methimazole
B) Propylthiouracil
C) Radioactive iodine ablation
D) Thyroidectomy
Correct Answer: C) Radioactive iodine ablation
Rationale: This patient has Graves' disease with ophthalmopathy. Radioactive iodine (RAI) is first-line definitive treatment for Graves' disease in
the United States. While ophthalmopathy is a relative contraindication, mild exophthalmos can be managed with corticosteroids during RAI.
Methimazole and PTU are temporary measures. Thyroidectomy is reserved for large goiters or RAI failure .
Question 12: A 72-year-old man with atrial fibrillation has been taking warfarin with INR维持在 2.5-3.5 for the past year. He now presents with
an INR of 6.8 but has no bleeding symptoms. What is the most appropriate management?
