Neurologic and Endocrine Emergencies
- Differentiate the data collection findings, priority interventions, and safety precautions for acute cerebrovascular events, seizures, and increased intracranial pressure within the practical nurse scope.
- Identify clinical manifestations and emergency management steps for acute diabetic crises, including hypoglycemia, diabetic ketoacidosis, and hyperosmolar hyperglycemic state.
- Describe the practical nurse's role in collecting data, assisting with emergency interventions, and reinforcing education for thyroid storm, myxedema coma, and Addisonian crisis.
Cerebrovascular Emergencies: Transient Ischemic Attack and Acute Stroke
A transient ischemic attack is a temporary episode of focal neurologic dysfunction caused by ischemia without acute infarction. In this condition, blood flow is briefly impaired, but the tissue does not undergo permanent death, and symptoms usually resolve within minutes to an hour. In contrast, an ischemic stroke results from the actual blockage of a cerebral vessel, leading to tissue damage, whereas a hemorrhagic stroke results from bleeding into the brain tissue or the space surrounding the brain. Think of an ischemic stroke like an obstructed water pipe that cuts off supply to a room, while a hemorrhagic stroke is like a ruptured pipe that floods the surrounding structure.
Rapid recognition is vital when a client displays acute neurological deficits. The FAST screening tool provides a structured way to evaluate Facial droop, Arm weakness, Speech difficulty, and Time to call emergency services. The licensed practical/vocational nurse (LPN/VN) promptly collects and reports the client's last-known-well time and, if known, symptom-onset time to the registered nurse (RN). This data collection is critical because client eligibility for time-sensitive stroke treatments depends in part on these exact times.
Clinical care during an evolving stroke requires strict adherence to safety protocols. The LPN/VN maintains an acute stroke client NPO, including withholding oral medications, until qualified staff complete a dysphagia screen and oral intake is authorized according to protocol. For positioning, the LPN/VN positions an acute stroke client's head and the head of the bed as ordered, keeping the head in a neutral position, and immediately reports any changes in breathing or neurologic status to the RN. The LPN/VN performs focused neurological checks, including pupil size and reactivity, level of consciousness, and limb motor strength, reporting any acute changes to the RN.
Medication safety is an essential component of stroke management. The LPN/VN does not administer antiplatelet or anticoagulant medication for a suspected acute stroke before intracranial hemorrhage has been excluded and the medication has been prescribed. During and after thrombolytic administration, the LPN/VN monitors the client closely for signs of bleeding, including epistaxis, hematuria, and sudden worsening of mental status. For long-term management, the LPN/VN reinforces teaching on blood pressure control, smoking cessation, and adherence to prescribed antiplatelet therapy for secondary stroke prevention.
Common mistakes
- Placing bite blocks, oral airways, or other objects into the mouth of an actively seizing client, which risks severe airway obstruction and dental trauma.
- Administering antiplatelet or anticoagulant medications to a client with acute stroke symptoms before intracranial hemorrhage has been officially excluded.
- Using rapid active rewarming methods on a client experiencing myxedema coma, which can cause sudden peripheral vasodilation and vascular collapse instead of safe, gradual passive warming.
- Offering oral juice or carbohydrates to an unconscious hypoglycemic client rather than administering prescribed injectable glucagon and positioning the client on their side.
Key points
- Transient ischemic attack symptoms usually resolve within an hour but can last longer without acute infarction; for suspected stroke, the LPN/VN promptly reports FAST findings and last-known-well time to the RN, maintains NPO status until the client passes a dysphagia screen and oral intake is authorized, and gives antiplatelets only after hemorrhage is excluded and they are prescribed.
- During an active seizure, protect the client from injury, position them on their side when feasible, avoid placing anything in the mouth, and treat status epilepticus lasting 5 minutes or longer as an emergency requiring immediate RN notification and benzodiazepine support.
- A changing level of consciousness may be an early sign of increased intracranial pressure; the LPN/VN immediately reports Cushing's triad or new abnormal posturing to the RN and activates emergency escalation according to protocol while maintaining prescribed positioning and performing focused checks.
- For a client with hypoglycemia below 70 mg/dL who is alert and can safely swallow, give about 15 grams of fast-acting carbohydrate and recheck glucose in 15 minutes; if the client cannot safely swallow and has no intravenous access, administer prescribed glucagon within scope, position the client on their side, and promptly report to the RN.
- DKA and HHS generally require initial isotonic intravenous fluids; insulin is started according to the prescribed protocol after potassium is checked and any significant hypokalemia is addressed, with serial potassium and glucose checks and dextrose added at the indicated glucose threshold.
- Endocrine emergencies require rapid identification: manage thyroid storm with cooling and antithyroid drugs while avoiding aspirin, treat myxedema coma with gradual passive warming and thyroid hormone, and address Addisonian crisis with intravenous hydrocortisone and isotonic fluid resuscitation.
