ESTUDYR
Introduction
This comprehensive case study pack is designed to prepare aspiring
registered nurses for the Next Generation NCLEX-RN (NGN)
examination. Each case study is meticulously crafted to reflect the
complexity and critical thinking required by the NGN, focusing on the
six cognitive skills of the National Council of State Boards of Nursing
(NCSBN) Clinical Judgment Measurement Model (NCJMM):
Recognize Cues, Analyze Cues, Prioritize Hypotheses, Generate
Solutions, Take Actions, and Evaluate Outcomes.
How to Use This Pack
For each case study, read the scenario carefully. Then, work through
each step of the NCJMM, documenting your thought process before
reviewing the provided answers and rationales. This active learning
approach will enhance your clinical judgment and decision-making
skills.

Case Study 1: Cardiac - Myocardial Infarction (MI)
Scenario
Mr. John Doe, a 62-year-old male, presents to the emergency department with sudden
onset of crushing chest pain radiating to his left arm and jaw. He describes the pain as an
8/10, accompanied by shortness of breath, diaphoresis, and nausea. His past medical history
includes hypertension and hyperlipidemia. He is currently on lisinopril and atorvastatin. On
arrival, his vital signs are: BP 150/90 mmHg, HR 110 bpm, RR 24 breaths/min, SpO2 92% on
room air, Temp 37.0°C (98.6°F). An ECG shows ST-segment elevation in leads II, III, and aVF.
NCJMM Steps
1. Recognize Cues (What matters most?)
• Identify relevant and irrelevant information from the scenario.
• List all significant subjective and objective data.
2. Analyze Cues (What could it mean?)
• Interpret the identified cues.
• Cluster related cues and identify patterns.
• Relate findings to Mr. Doe's medical history and current presentation.
3. Prioritize Hypotheses (What is the most likely problem?)
• Formulate potential nursing diagnoses or problems based on your analysis.
• Prioritize these hypotheses based on urgency and risk to the patient.
4. Generate Solutions (What can I do?)
• Develop a list of potential interventions for your priority hypotheses.
• Consider both independent and collaborative nursing actions.
5. Take Actions (What will I do?)
• Select the most appropriate interventions from your generated solutions.
• Provide a rationale for each chosen action.
,ESTUDYR
6. Evaluate Outcomes (Did it work?)
• Describe the expected outcomes for your chosen actions.
• How would you assess if the interventions were effective?
Answers and Rationales
1. Recognize Cues
• Relevant: 62-year-old male, sudden onset crushing chest pain (8/10), radiating to
left arm and jaw, shortness of breath, diaphoresis, nausea, history of hypertension
and hyperlipidemia, current medications (lisinopril, atorvastatin), BP 150/90, HR 110,
RR 24, SpO2 92% on room air, ECG shows ST-segment elevation in leads II, III, aVF.
• Irrelevant: Temp 37.0°C (98.6°F) (within normal limits, not directly indicative of
acute cardiac event).
2. Analyze Cues
• Acute Coronary Syndrome (ACS)/Myocardial Infarction (MI): Crushing chest pain
radiating to left arm and jaw, diaphoresis, nausea, shortness of breath, and ST-
segment elevation on ECG are classic signs of MI. The patient's history of
hypertension and hyperlipidemia are significant risk factors.
• Compromised Oxygenation: SpO2 92% on room air and RR 24 indicate impaired gas
exchange, likely due to cardiac compromise.
• Increased Cardiac Workload: Tachycardia (HR 110) and elevated blood pressure (BP
150/90) suggest the heart is working harder, increasing myocardial oxygen demand.
3. Prioritize Hypotheses
1 Acute Myocardial Infarction (MI) / Ineffective Myocardial Tissue Perfusion: This is
the most life-threatening condition, requiring immediate intervention to restore
blood flow and minimize cardiac damage.
2 Impaired Gas Exchange: Directly related to the cardiac event and requires prompt
attention to improve oxygenation.
3 Acute Pain: While important, it is secondary to the underlying cardiac event and will
be addressed concurrently with interventions for MI.
4. Generate Solutions
• Administer oxygen via nasal cannula.
• Administer nitroglycerin sublingually.
• Administer aspirin chewable.
• Administer morphine IV.
• Obtain IV access.
, ESTUDYR
• Initiate continuous cardiac monitoring.
• Prepare for cardiac catheterization/PCI.
• Draw blood for cardiac enzymes (troponin, CK-MB).
• Provide emotional support and reassurance.
• Maintain bed rest with head of bed elevated.
5. Take Actions
4 Administer oxygen via nasal cannula at 2-4 L/min: To improve myocardial oxygen
supply and alleviate shortness of breath.
5 Administer nitroglycerin 0.4 mg sublingually every 5 minutes for up to 3 doses (if
BP stable): To cause vasodilation, reduce preload and afterload, and improve
coronary blood flow.
6 Administer aspirin 325 mg chewable: To inhibit platelet aggregation and prevent
further clot formation.
7 Establish IV access (two large-bore IVs): For medication administration and fluid
resuscitation if needed.
8 Initiate continuous 12-lead ECG monitoring: To monitor for dysrhythmias and
changes in ST segments.
9 Prepare for immediate transfer to cardiac catheterization lab: To re-establish
coronary blood flow (e.g., PCI).
10 Administer morphine sulfate IV 2-4 mg: To alleviate severe pain, reduce anxiety,
and decrease cardiac workload (vasodilation).
6. Evaluate Outcomes
• Pain Relief: Patient reports decreased chest pain (e.g., from 8/10 to 2/10).
• Improved Oxygenation: SpO2 > 94%, respiratory rate within normal limits,
decreased dyspnea.
• Stable Hemodynamics: BP and HR within acceptable limits, absence of significant
dysrhythmias.
• Reperfusion: Resolution of ST-segment elevation on ECG, indicating successful re-
establishment of blood flow.
• Reduced Anxiety: Patient appears calmer and more comfortable.
