An alert patient with suspected hypoglycemia can swallow safely. Which action best follows the initial treatment guidance?
- A
Give a carbohydrate-and-protein snack immediately, then check glucose in an hour.
- B
Give 15 g of fast-acting carbohydrate and recheck glucose after 15 minutes.
- C
Give nothing by mouth and wait for the next scheduled meal.
- D
Give prescribed IV dextrose without checking whether the patient can swallow.
In most people, hypoglycemia is a blood glucose level below . Enter the threshold in mg/dL.
Which presentation best fits hyperosmolar hyperglycemic state (HHS)?
- A
Rapid onset with abdominal pain, significant ketones, and metabolic acidosis.
- B
Gradual onset with marked thirst and urination, dehydration, and increased osmolality, usually without substantial ketosis or acidosis.
- C
Low glucose with shakiness and sweating that resolves after carbohydrate.
- D
High glucose with significant ketones and acidosis as defining features.
What acid-base disturbance is part of the defining pattern of diabetic ketoacidosis (DKA)?
A single glucose result is enough to establish or exclude a hyperglycemic crisis.
- A
True
- B
False
A patient with suspected severe hypoglycemia is unconscious and cannot swallow safely. Which actions are appropriate? Select all that apply.
- A
Give nothing by mouth.
- B
Call for emergency assistance.
- C
Administer prescribed glucagon or IV dextrose according to the care setting’s protocol.
- D
Offer juice if the patient appears likely to regain consciousness soon.
- E
Protect the patient from injury and position to help protect the airway.
During DKA or HHS treatment, insulin is generally delayed while potassium is replaced if the potassium level is below . Enter the threshold with its unit.
During DKA treatment, below what glucose threshold in mg/dL are prescribed fluids generally adjusted to include dextrose so insulin can continue until ketoacidosis resolves?
Which monitoring actions are consistent with care during DKA or HHS treatment? Select all that apply.
- A
Check bedside glucose every 1–2 hours during crisis treatment, as recommended by adult consensus guidance.
- B
Trend electrolytes, particularly potassium.
- C
Monitor fluid intake and output and vital signs.
- D
Stop assessing neurologic status once glucose begins to fall.
- E
Monitor neurologic status and response to treatment; monitor cardiac rhythm when indicated, especially with abnormal potassium.
Which combination best reflects the key laboratory pattern used to identify DKA in adults?
- A
Glucose at least 600 mg/dL and hyperosmolality, without substantial ketones or acidosis.
- B
Glucose at least 200 mg/dL or known diabetes, significant ketones, and acidosis.
- C
Any elevated glucose level, even without ketones or acidosis.
- D
Known diabetes and dehydration, with no need to assess ketones or acid-base status.
For an adult with suspected DKA or HHS who has no cardiac or renal compromise, which initial fluid approach is described by consensus guidance?
- A
Give a fixed 100 mL/hour for the first 24 hours, regardless of patient factors.
- B
Use an initial isotonic saline or balanced crystalloid rate of 500–1,000 mL/hour for the first 2–4 hours, then individualize treatment.
- C
Avoid IV fluids until glucose has normalized.
- D
Use the same rapid fluid replacement rate for all patients, including older adults and those with heart or kidney disease.
A patient is improving after treatment for DKA and the team is preparing to stop the IV insulin infusion. What needs to be in place before stopping the infusion, and why is overlap important?
A patient has recovered from hypoglycemia, but their next meal is not soon. What type of snack should you provide?
An alert patient who can swallow safely receives fast-acting carbohydrate for hypoglycemia. After how many minutes should you recheck their glucose?
An alert patient with symptoms of hypoglycemia can swallow safely. Which immediate treatment is appropriate?
- A
Withhold treatment until a glucose measurement is available.
- B
Give 15 g of fast-acting carbohydrate by mouth.
- C
Give a carbohydrate-and-protein snack instead of fast-acting carbohydrate.
- D
Give nothing by mouth and administer IV dextrose.
A patient has symptoms strongly suggesting hypoglycemia, but a point-of-care glucose test is not immediately available. What should you do?
- A
Wait until a glucose meter is available before taking any action.
- B
Give insulin to prevent a later rise in glucose.
- C
Treat the suspected low and check glucose as soon as possible.
- D
Offer food only after confirming the glucose is below 70 mg/dL.
True or false: A glucose level below the usual high levels rules out diabetic ketoacidosis, including in a person taking an SGLT2 inhibitor.
- A
True
- B
False
An older adult with type 2 diabetes has marked hyperglycemia, profound dehydration, and altered mental status. Which laboratory pattern is most consistent with HHS?
- A
Severe hyperglycemia, dehydration, and hyperosmolality, usually without substantial ketonemia or acidosis.
- B
Rapid onset with significant ketones and metabolic acidosis as defining features.
- C
Low glucose with reduced awareness of warning symptoms.
- D
Mild dehydration with no change in serum osmolality.
An adult with suspected DKA also has heart failure. How should the initial fluid replacement plan be approached?
- A
Use the general initial fluid rate without modification because it is recommended for all adults.
- B
Use more cautious, individualized fluid replacement.
- C
Avoid fluids until glucose has normalized.
- D
Rapidly increase fluids to correct dehydration as quickly as possible.
