, SECTION 1 | Clinical Decision-Making | Q1-Q15 | Exam 3 | Diagnostic Reasoning for Nurse Practitioners | Questions
Q1 Question 1 of 75
Q1. A 54-year-old male presents to the clinic with new-onset chest pressure that began 30 minutes ago while
shoveling snow. The pain radiates to his left arm and jaw. Vital signs are stable. Using the clinical
decision-making process, which step should the nurse practitioner take first?
A. Schedule a stress test for the following week
B. Prescribe a proton pump inhibitor for suspected reflux
C. Activate emergency medical services and administer aspirin 325 mg chewed
D. Perform a complete physical examination before any intervention
Correct Answer: C
Rationale:
Acute chest pain with cardiac risk factors requires immediate action: activate EMS, administer aspirin, and obtain an
ECG within 10 minutes per ACS guidelines. Scheduling a stress test delays care for suspected acute coronary
syndrome; PPI therapy is inappropriate without ruling out ACS; full physical exam delays critical intervention.
Time-sensitive decision-making prioritizes life-threatening conditions.
Q2 Question 2 of 75
Q2. A 42-year-old female with fatigue and weight gain has a TSH of 8.5 mIU/L and free T4 of 0.6 ng/dL. Using
pattern recognition, which clinical decision is most appropriate?
A. Diagnose primary hypothyroidism and initiate levothyroxine therapy
B. Diagnose secondary hypothyroidism and order a pituitary MRI
C. Diagnose hyperthyroidism and prescribe methimazole
D. Repeat labs in 6 months as the results are borderline
Correct Answer: A
Rationale:
Elevated TSH with low free T4 is diagnostic of primary hypothyroidism requiring levothyroxine replacement. Secondary
hypothyroidism shows low TSH with low T4; hyperthyroidism shows low TSH with high T4; repeating labs in 6 months
delays needed treatment. Pattern recognition integrates lab values with clinical presentation for efficient diagnosis.

, Q3 Question 3 of 75
Q3. A 68-year-old male with COPD presents with increased dyspnea, purulent sputum, and ankle swelling. He
has used his rescue inhaler every 2 hours for 24 hours. Which clinical decision-making framework best guides
the nurse practitioner's next steps?
A. Order every available diagnostic test before forming a hypothesis
B. Analyze cues, identify the problem, generate solutions, take action, and evaluate outcomes
C. Refer the patient to a pulmonologist without initial management
D. Prescribe antibiotics empirically without further assessment
Correct Answer: B
Rationale:
Tanner's clinical judgment model includes noticing, interpreting, responding, and reflecting, while the NCSBN's clinical
judgment model includes recognizing cues, analyzing cues, prioritizing hypotheses, generating solutions, taking action,
and evaluating outcomes. Ordering all tests is inefficient; referral without management delays care; empiric antibiotics
without assessment ignores other causes of COPD exacerbation.
Q4 Question 4 of 75
Q4. A 35-year-old female presents with right lower quadrant abdominal pain, fever, and anorexia that began 12
hours ago. Physical examination reveals rebound tenderness at McBurney point. The white blood cell count is
16,000. Which decision is most appropriate?
A. Refer for emergent surgical evaluation for suspected appendicitis
B. Discharge with instructions to follow up in 1 week
C. Prescribe oral antibiotics for suspected gastroenteritis
D. Order an abdominal ultrasound for suspected cholecystitis
Correct Answer: A
Rationale:
The combination of RLQ pain, McBurney point tenderness, fever, anorexia, and leukocytosis is classic for acute
appendicitis requiring emergent surgical evaluation. Discharging risks perforation; gastroenteritis typically causes
diffuse pain and diarrhea; cholecystitis causes RUQ pain. Surgical decision-making balances rupture risk against
operative risk. CT imaging may confirm diagnosis in equivocal cases.

, Q5 Question 5 of 75
Q5. A 70-year-old male presents with sudden-onset left-sided weakness and slurred speech that began 45
minutes ago. Blood pressure is 190/100. CT scan shows no hemorrhage. Using time-sensitive decision-making,
which action should the nurse practitioner prioritize?
A. Administer intravenous alteplase within the 3 to 4.5 hour treatment window
B. Lower blood pressure aggressively with IV labetalol before any other intervention
C. Transfer the patient to a skilled nursing facility for rehabilitation
D. Schedule an outpatient MRI for further evaluation next week
Correct Answer: A
Rationale:
Acute ischemic stroke within 3-4.5 hours of symptom onset qualifies for IV alteplase, which must be administered before
BP is aggressively lowered (unless BP exceeds 185/110, then lowered to below 185/110 before tPA). Transfer to SNF
delays acute care; outpatient MRI is inappropriate. Time is brain, with each minute of delay resulting in 1.9 million
neuron losses.
Q6 Question 6 of 75
Q6. A 28-year-old female presents with chronic widespread pain, fatigue, and sleep disturbance. Examination
reveals 11 of 18 tender points. Which clinical decision-making approach should the nurse practitioner use?
A. Empirically prescribe opioids for pain control without further evaluation
B. Order extensive imaging including MRI of the entire spine
C. Refer the patient for psychiatric evaluation for somatization
D. Apply diagnostic criteria, rule out mimics, and confirm fibromyalgia before initiating therapy
Correct Answer: D
Rationale:
Fibromyalgia diagnosis requires applying ACR criteria (widespread pain index and symptom severity), ruling out mimics
(hypothyroidism, autoimmune disease), and confirming before initiating multimodal therapy including exercise, CBT,
and medications (SNRIs, pregabalin). Opioids are not first-line and may worsen outcomes; extensive imaging is not
indicated; psychiatric referral without medical workup is premature.
