CDCES Emergency Response Procedures 2 — Questions and Answers
Question 1: A patient calls the CDCES educator reporting dizziness, sweating, and a blood glucose of 58 mg/dL. They are conscious and able to swallow. What is the recommended first treatment?
- Administer 1 mg IM glucagon immediately
- Give 15-20 grams of fast-acting carbohydrates and recheck in 15 minutes (Correct answer)
- Administer intravenous dextrose
- Have the patient drink a full glass of orange juice (24 oz)
Correct answer: Give 15-20 grams of fast-acting carbohydrates and recheck in 15 minutes
The 15-15 Rule: give 15-20g of fast-acting carbohydrates, wait 15 minutes, and recheck blood glucose; this is first-line for a conscious, symptomatic patient.
For a conscious patient with mild-to-moderate hypoglycemia (BG below 70 mg/dL with symptoms), the 15-15 Rule is the standard of care: consume 15-20 grams of fast-acting carbohydrates (glucose tablets, 4 oz juice, regular soda, or glucose gel), wait 15 minutes, and recheck BG. If still below 70 mg/dL, repeat. Once BG normalizes, a small snack with protein and complex carbohydrate prevents rebound hypoglycemia. Glucagon and IV dextrose are reserved for severe hypoglycemia (loss of consciousness or inability to swallow). A full 24-oz glass of OJ provides more than 50g carbohydrates -- excessive for initial treatment.
Question 2: A patient with type 1 diabetes is found unconscious by their family member. They are not able to swallow. Which emergency intervention should the family member perform FIRST?
- Force orange juice into the patient's mouth
- Administer prescribed emergency glucagon and call 911 (Correct answer)
- Give insulin to correct suspected hyperglycemia
- Rub honey on the patient's gums
Correct answer: Administer prescribed emergency glucagon and call 911
For an unconscious patient with suspected severe hypoglycemia, administer emergency glucagon and call 911 immediately; forcing fluids risks aspiration.
Severe hypoglycemia with altered consciousness or inability to swallow requires emergency glucagon (kit, autoinjector, or nasal glucagon) and activation of emergency medical services (911). Forcing oral fluids into an unconscious patient is dangerous and can cause aspiration. Rubbing honey on gums provides minimal glucose and delays proper treatment. Insulin would worsen hypoglycemia and is contraindicated. The CDCES provides anticipatory guidance to caregivers: always have glucagon available, know how to use it, and never hesitate to call 911.
Question 3: During a group DSMES class, a participant develops slurred speech, confusion, and diaphoresis. Their glucometer reads LOW. What is the CDCES's most appropriate immediate action?
- Ask the participant to go to the restroom and check again
- Treat for severe hypoglycemia using the facility's emergency protocol and activate EMS (Correct answer)
- Continue the class and monitor the participant from a distance
- Administer insulin correction to address the potential error reading
Correct answer: Treat for severe hypoglycemia using the facility's emergency protocol and activate EMS
A LOW glucometer reading with neurological symptoms indicates severe hypoglycemia requiring immediate emergency treatment and EMS activation.
LOW on a glucometer indicates BG below the device's measurable range (typically below 20-40 mg/dL). Combined with neurological symptoms (slurred speech, confusion, diaphoresis), this constitutes a hypoglycemic emergency. The CDCES should immediately activate the facility's emergency response protocol: if the patient can safely swallow and is semi-conscious, attempt rapid oral glucose; if unable to swallow, administer emergency glucagon and call 911. All DSMES programs should have emergency protocols, and CDCESs must be trained in their implementation.
Question 4: A patient with type 2 diabetes on an SGLT2 inhibitor calls reporting vomiting, inability to tolerate fluids, and blood glucose of 210 mg/dL. Urine ketones are large. What condition should the CDCES be most concerned about?
- Mild dietary indiscretion
- Euglycemic diabetic ketoacidosis (euDKA) (Correct answer)
- Hyperosmolar hyperglycemic state (HHS)
- Reactive hypoglycemia
Correct answer: Euglycemic diabetic ketoacidosis (euDKA)
SGLT2 inhibitors can cause euglycemic DKA -- DKA with relatively normal or mildly elevated blood glucose -- which may be missed because glucose is not markedly elevated.
Euglycemic diabetic ketoacidosis (euDKA) is a recognized complication of SGLT2 inhibitor therapy, occurring when ketone production exceeds the body's buffering capacity while glucose remains below 250 mg/dL (due to the drug's glucosuric effect). Patients may present with nausea, vomiting, abdominal pain, and large ketones with only mildly elevated glucose, making the diagnosis easy to miss. The CDCES must educate patients on SGLT2 inhibitor sick-day rules: stop the medication during illness, surgery, or fasting, and seek immediate care if ketones are elevated.
Question 5: A patient with type 2 diabetes is found to have blood glucose of 620 mg/dL, severe dehydration, and altered mental status but NO significant ketones. Which condition is most likely, and what is the priority emergency response?
- DKA; administer IV insulin immediately without fluids
- HHS (hyperosmolar hyperglycemic state); call 911 for IV fluid resuscitation (Correct answer)
- Severe reactive hypoglycemia; give oral glucose
- Hyperglycemic urgency; recommend increased water intake at home
Correct answer: HHS (hyperosmolar hyperglycemic state); call 911 for IV fluid resuscitation
Severely elevated glucose with dehydration, altered mental status, and no significant ketones points to HHS, a life-threatening emergency requiring IV fluid resuscitation and hospitalization.
Hyperosmolar hyperglycemic state (HHS) is characterized by extreme hyperglycemia (above 600 mg/dL), hyperosmolality, severe dehydration, and altered mental status WITHOUT significant ketoacidosis. It occurs most often in older adults with type 2 diabetes. The mortality rate is 5-20%. Emergency management requires hospitalization for IV normal saline resuscitation, careful electrolyte management, and insulin therapy after fluid status is partially restored. The CDCES must recognize HHS warning signs and direct patients/families to call 911 immediately.
Question 6: Which of the following best describes the CDCES's role in a patient's emergency action plan for severe hypoglycemia?
- Prescribing emergency glucagon directly to the patient
- Educating the patient and caregivers on glucagon administration and creating a written action plan (Correct answer)
- Ensuring the hospital has glucagon stocked on the nursing unit
- Performing emergency glucagon administration on all patients during clinic visits
Correct answer: Educating the patient and caregivers on glucagon administration and creating a written action plan
The CDCES's role is education and action plan development: teaching patients and caregivers about glucagon use, hypoglycemia recognition, and when to call 911.
The CDCES does not prescribe glucagon but plays a critical role in ensuring that patients at risk for severe hypoglycemia have a written emergency action plan. This includes: educating the patient and all caregivers on hypoglycemia recognition (symptoms, blood glucose thresholds), proper glucagon administration for the specific product prescribed (nasal, autoinjector, or kit), when to call 911, post-episode follow-up steps, and review and update of the plan at each DSMES encounter. Caregiver training on glucagon is a CBDCE exam priority topic.
