The situation

Jessie, an RPN at a group home, notices Dylan is pale, sweaty, and shaky during a basketball game. Dylan reports feeling nauseous and lightheaded before collapsing, unresponsive. Jessie checks Dylan’s insulin pump, confirms a low blood sugar reading, and makes a nursing diagnosis of hypoglycemia​.

Read the full case

Jessie has been working at the group home as an RPN for three months. While supervising the boys outside, he notices a group playing a lively game of p​​ickup basketball. Jessie is pleased to see Dylan among them. He knows that Dylan, who has diabetes, has often struggled with his self-image and has been reluctant to participate in group activities. Seeing him join in feels like a positive step in Dylan’s social and emotional well-being.


After a few minutes, during a time out in the game, Dylan approaches Jessie. He looks unsettled and tells Jessie he isn’t feeling well—complaining of nausea, shakin​​ess, and light-headedness. As Dylan speaks, Jessie observes that his skin is pale and clammy with visible beads of sweat on his forehead. Concerned, Jessie immediately assists Dylan to sit on the ground so that he can perform a focused assessment and prevent a fall.


As Jessie kneels be​​side him and begins his assessment, Dylan suddenly slumps forward, becoming unresponsive. Jessie quickly calls out for help from nearby staff. While another colleague rushes to phone 9-1-1, Jessie checks Dylan’s airway and responsiveness, then examines his insulin pump to see his current blood glucose reading. The monitor confirms what Jessie suspects: Dylan’s blood sugar is dangerously low.


Combining this objective fi​​nding with his clinical observations and judgment, Jessie concludes that Dylan is experiencing hypoglycemia. With emergency services on the way, Jessie prepares to act within his role and scope of practice to stabilize Dylan until paramedics arrive.

If Jessie had not obtained the compe​tencies to treat hypoglycemia, he would not meet the practice standard Registered​ Psychiatric Nurses: Acting Within Autonomous Scope of Practice​. He would still recognize and diagnose the condition, call 9-1-1, and request a competent colleague or a client-specific order for treatment. While waiting, he would monitor Dylan, provide reassurance, and ensure safety. Jessie would document his assessment and actions, hand over to paramedics, and follow up with his manager to arrange the training needed to treat hypoglycemia autonomously. 

Jessie's actions​​

​​Step 1: Assessment 

Observes Dylan becoming pale, sweaty, nauseous, and lightheaded. Dylan collapses, unresponsive. Jessie checks Dylan’s insulin pump, confirms a low blood sugar reading, and assesses the situation.

Step 2: Diagnosi​s

Makes a nursing diagnosis of hypoglycemia based on assessment, signs and symptoms, and blood glucose reading.

Step 3: Decision and action​​ 

If compet​​ent​: ​​If competent and supported by a DST, Jessie administers treatment (e.g., D50W) for hypoglycemia within his autonomous scope in keeping with the practice standard​​ Reg​​istered​ Psychiatric Nurses: Acting Within Autonomous Scope of Practice​.

If not compet​​ent​:​ If Jessie has not completed the required education to administer D50W, he does not meet the standard for acting within autonomous scope. In this case, Jessie request​​s a colleague who is competent to provide treatment, calls 9-1-1, and ensures Dylan is monitored until help arrives.

Step 4: Follow-​up 

Calls 9-1-1, provides a handover to paramedics, documents the incident, and updates Dylan’s physician and care team.

​​​Apply the standard

Dylan collapses during a basketball game and shows signs of hypoglycemia. What is within Jessie’s autonomous scope of practice as an RPN?

Option A: Administer D50W for hypoglycemia without additional education.

Not correct. RPNs must first complete the required additional education and follow an employer-approved DST before autonomously administering D50W

Option B: Diagnose hypoglycemia and treat with nursing interventions if competent and supported by a DST.

Correct. RPNs may diagnose and treat hypoglycemia within their autonomous scope, provided they are competent, follow BCCNM standards and conditions, and act within organizational policy.

Option C: Prescribe insulin to stabilize Dylan’s diabetes.

Not correct. Prescribing insulin is not within an RPN’s autonomous scope of practic​e.

Option D: Wait for paramedics before providing any treatment.

Not correct. While emergency services must be called, delaying treatment could place Dylan at risk. Nurses are expected to act within their autonomous scope when competent to do so.

​​​How Jessie meets the standards

Jessie demonstrates that he is meeting all expectations in the practice standard​​ Reg​​istered​ Psychiatric Nurses: Acting Within Autonomous Scope of Practice​. This includes:

  • Conducting an assessment and diagnosing hypoglycemia based on clinical findings and a blood glucose reading.
  • Considering risks, benefits, and the predictable outcomes of treatment.
  • Acting safely within his competence, using an employer-approved DST.
  • Communicating with colleagues, paramedics, and Dylan’s physician.
  • Docum​enting his assessment, treatment, communication, and outcomes.

​​​Jessie may diagnose and treat hypoglycemia autonomously, provided he:

  • Completes the additional education required to administer D50W.
  • Follows BCCNM standards, limits, and conditions.
  • Uses his employer’s DST and adheres to organizational policies.
  • Acts within his individual competence.

​​​Acting within autonomous scope of practice – Recap

Within their autonomous scope of practice, RPNs can independently diagnose conditions and provide treatment with nursing activities when they are educated, competent, and authorized to do so, provided they meet any limits and conditions set by BCCNM and employer policy. This includes:

Non-restricted activities:

  • Monitoring vital signs and reporting changes
  • Supporting daily living needs (feeding, mobility, hygiene)
  • Health teaching and counselling
  • Delivering mental health interventions wit​​hin their role

​Restricted activities that do not require an order (within competence and BCCNM limits/conditions):

  • Administering oxygen to a hypoxic client using an approved DST
  • Giving immunizations under approved DSTs
  • Administering D50W for hypoglycemia (after completing additional education and using an approved DST)
  • Performing urinary catheterization when permitted and competent 

Outside RPN autonomous scope: Activities that require an order (i.e., initiating IV therapies outside DSTs), or any activity restricted by BCCNM standards, employer policy, or legislation. 

Key point: Even when an activity falls within autonomous scope, RPNs must always apply the four controls on practice—legislation/regulation, BCCNM standards, employer policy, and individual competence—before acting.
