Question 21
Regular
A diagnosis of hyperglycemic hyperosmolar state (HHS) is made for a patient with type 2 diabetes who is brought to the emergency department in an unresponsive state. Which of the following actions should the nurse anticipate?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Insert a large-bore IV catheter. This action is essential for the rapid administration of fluids and medications, which are critical in managing the severe dehydration and electrolyte imbalances characteristic of hyperglycemic hyperosmolar state in a patient who is unresponsive.
A: Give 50% dextrose as a bolus. This treatment is inappropriate as it could exacerbate hyperglycemia, potentially worsening the patient's condition rather than addressing the underlying issues of HHS.
C: Initiate oxygen by nasal cannula. While oxygen may be needed if respiratory distress is present, it does not directly address the immediate concerns of fluid resuscitation and metabolic derangements in HHS.
D: Administer glargine insulin. Although insulin is important in managing hyperglycemia, immediate fluid resuscitation and stabilization take precedence in an unresponsive patient experiencing hyperglycemic hyperosmolar state.

Question 22
Regular
A patient with type 1 diabetes who is on glargine and lispro insulin has called the clinic to report symptoms of a sore throat, cough, fever, and blood glucose level of 11.7 mmol/L. Which of the following information should the nurse tell the patient?
Correct!
Incorrect
The correct answer is: B
Rationale
Monitor blood glucose every 4 hours and notify the clinic if it continues to rise.
Monitoring blood glucose levels is crucial for a patient with type 1 diabetes, especially during illness. Elevated glucose levels can indicate insufficient insulin action, necessitating timely interventions to avoid complications. Regular checks help in managing diabetes effectively while addressing any potential infection.
A: Use only the lispro insulin until the symptoms of infection are resolved. Relying solely on lispro could lead to inadequate basal insulin coverage, risking further hyperglycemia and complications.
C: Decrease intake of carbohydrates until glycosylated hemoglobin is less than 7%. Adjusting carbohydrate intake based on hemoglobin A1c is inappropriate in acute illness situations, as immediate blood glucose control is essential.
D: Limit intake of calorie-containing liquids until the glucose is less than 6.7 mmol/L. This approach ignores the need for adequate hydration and nutrition during illness, which can exacerbate health issues.

Question 25
Regular
Which of the following questions by the nurse will help identify autonomic neuropathy in a patient with diabetes?
Correct!
Incorrect
The correct answer is: B
Rationale
Bloating after eating is a significant indicator of autonomic neuropathy, as it suggests gastrointestinal dysmotility, a common complication in diabetic patients. This symptom can reflect the impaired autonomic regulation of digestive processes, leading to discomfort and potential nutritional issues.
A: Have you observed any recent skin changes? Skin changes may relate to various dermatological conditions, not specifically pointing to autonomic dysfunction, thus lacking direct relevance to neuropathy assessment.
C: Do you need to increase your insulin dosage when you are stressed? While stress affects glucose levels, it does not directly assess autonomic neuropathy, focusing instead on insulin management rather than neurological function.
D: Have you noticed any painful new ulcerations or sores on your feet? Although foot ulcers can indicate complications in diabetes, they primarily suggest peripheral neuropathy rather than the autonomic neuropathy that affects visceral functions.
