Assessment 2: Critical Discussion Essay Management of Polysubstance Overdose

Written Assessment 2: Critical Discussion Essay

Introduction

• Brief overview and relevant history of chosen patient.
• Identify interventions, for example fluid resuscitation / sedation / parental nutrition / pain management / blood glucose control / ICP management / therapeutic hypothermia.

Body of Assignment

• Identify relevant assessment data, for example urine output, blood pressure, central
  venous pressure, peripheral circulation, haemoglobin etc
• Interpret this data – is assessment data normal / abnormal. What does the data
  reveal, for example hypovolaemia
• Critically analyse your interpretation of the assessment data, for example why do
  you think the patient is hypovolaemic.
• Critically analyse the rationale for the intervention, for example why is fluid
  resuscitation required, rationale for fluid used to resuscitate, is the intervention
  supported by the literature. Critically analyse the impact this intervention has had on
  the patient.

Situation : She had been unconscious for an unknown duration of time when she was taken by EMS to the Emergency Department (ED). A Glasgow Coma Scale (GCS) score of 8 (E2: eyes open to pain, V1: no verbal response, M5: localizes pain), pinpoint pupils suggestive of opioid toxicity, intermittent apnea episodes lasting up to 30 seconds, oxygen saturation (SpO₂) of 86% on room air, respiratory rate of 8 breaths per minute, blood pressure (BP) of 84/52 mmHg, and heart rate (HR) of 96 beats per minute were all found during the initial evaluation (Blundell et al., 2024).

Summary of Assessment Requirements

The Written Assessment 2: Critical Discussion Essay requires students to critically analyse a patient case and demonstrate evidence-based reasoning in clinical decision-making. The key requirements include:

• Introduction: Provide a brief overview of the patient’s history and clinical presentation.
• Interventions: Identify the clinical interventions used (e.g., fluid resuscitation, sedation, pain management, blood glucose control, ICP management, therapeutic hypothermia).
• Body of Essay:
  • Present and interpret relevant assessment data such as urine output, BP, CVP, haemoglobin, circulation, and respiratory parameters.
  • Distinguish between normal and abnormal values.
  • Critically analyse the interpretation of the data (e.g., hypovolaemia, hypoxia, toxicity).
  • Critically evaluate the rationale for each intervention by referring to evidence-based literature.
  • Analyse the impact of each intervention on the patient’s clinical outcome.

The essay must reflect critical discussion , linking assessment findings with appropriate interventions, and supported by scholarly references.

Step-by-Step Approach by Academic Mentor

Step 1: Understanding the Case

The mentor first guided the student to carefully read the patient scenario:

• Patient unconscious, GCS of 8, pinpoint pupils, hypoventilation, hypoxia (SpO₂ 86%), hypotension (BP 84/52 mmHg), and intermittent apnea.

• Likely cause: opioid toxicity with possible complications like hypovolaemia and respiratory depression.

This step ensured the student could connect clinical presentation with underlying pathophysiology .

Step 2: Structuring the Essay

The mentor helped the student break down the assessment into clear sections:

1. Introduction – summarise the patient’s history and clinical situation.

2. Assessment Data – organise vital signs, GCS, oxygen saturation, and circulation findings.

3. Interpretation – highlight abnormal parameters (low GCS, hypoxia, hypotension) and what they suggest.

4. Interventions – match each abnormal finding with a clinical intervention (e.g., fluid resuscitation for hypotension, oxygen therapy/ventilation for apnea, naloxone for opioid toxicity).

5. Critical Analysis – discuss why each intervention was chosen, whether it was supported by literature, and its effectiveness.

Step 3: Critical Thinking and Evidence-Based Reasoning

The mentor encouraged the student to go beyond describing interventions and to ask:

• Why was this intervention necessary?
• What evidence supports its use in such cases?
• What impact did it have on stabilising the patient?
  For example, fluid resuscitation was critically analysed by linking hypotension and hypovolaemia to the need for IV crystalloids, supported by critical care guidelines.

Step 4: Linking Data with Interventions

Each abnormal assessment value was paired with a justified intervention:

• Low GCS (8): Need for airway protection and monitoring.
• Low BP (84/52): IV fluids to restore perfusion.
• Low SpO₂ and apnea: Immediate oxygen therapy and possible intubation.
• Pinpoint pupils: Indication for naloxone administration to reverse opioid effects.

Step 5: Outcome and Reflection

The mentor explained how to conclude by summarising:

• The patient’s condition improved due to timely interventions.
• The essay demonstrated how assessment data guided interventions.
• Literature supported each intervention, showing safe and evidence-based clinical reasoning.

Final Outcome

By following this structured process, the student successfully:

• Summarised the case and patient background clearly.
• Identified abnormal clinical data and linked it to the pathophysiological problem.
• Provided a critical rationale for interventions, supported with research evidence.
• Analysed the effectiveness of interventions on the patient’s clinical status.

Learning Objectives Covered

Through this assessment, the student achieved the following learning outcomes:

• Developed skills in interpreting abnormal clinical data .
• Strengthened critical analysis in linking assessment findings to interventions.
• Applied evidence-based practice in justifying interventions.
• Demonstrated the ability to structure a critical discussion essay in healthcare.
• Understood the impact of timely interventions on patient safety and recovery .
