NCLEX Endocrine Questions Questions
Question 1 of 5
The nurse administered 28 units of Humulin N, an intermediate-acting insulin, to a client diagnosed with type 1 diabetes at 1600. Which intervention should the nurse implement?
Correct Answer: A
Rationale: Humulin N peaks in 4–12 hours, risking nocturnal hypoglycemia. A bedtime snack prevents this. Lunch intake is irrelevant, morning glucose checks are too late, and protein alone is insufficient.
Question 2 of 5
The client with type 2 diabetes controlled with biguanide oral diabetic medication is scheduled for a computed tomography (CT) scan with contrast of the abdomen to evaluate pancreatic function. Which intervention should the nurse implement?
Correct Answer: B
Rationale: Biguanides (e.g., metformin) are held 48 hours before contrast CT to prevent lactic acidosis due to contrast-induced kidney injury. High-fat diets, consent, and enzymes are irrelevant.
Question 3 of 5
The client diagnosed with type 2 diabetes is admitted to the intensive care unit (ICU) with hyperosmolar hyperglycemic nonketotic syndrome (HHNS) coma. Which assessment data should the nurse expect the client to exhibit?
Correct Answer: C
Rationale: HHNS causes severe dehydration, leading to dry mucous membranes. Kussmaul’s respirations and ketone odor are DKA-specific, and diarrhea/pain are less common.
Question 4 of 5
Which assessment data indicate the client diagnosed with diabetic ketoacidosis is responding to the medical treatment?
Correct Answer: B
Rationale: Alertness and orientation indicate resolving DKA, as cerebral function improves. Persistent dehydration, acidosis (pH 7.29), and hypokalemia are not signs of improvement.
Question 5 of 5
Which arterial blood gas results should the nurse expect in the client diagnosed with diabetic ketoacidosis?
Correct Answer: D
Rationale: DKA causes metabolic acidosis (low pH 7.30, low HCO3 18) with compensatory respiratory alkalosis (low PaCO2 30). Other options show normal or alkalotic states.
