Diabetes Mellitus
1. A client with type 1 diabetes is admitted with confusion, diaphoresis, and a
blood glucose of 45 mg/dL. Which action should the nurse take first?
A. Administer 50% dextrose IV push
B. Give glucagon 1 mg IM
C. Provide orange juice with sugar
D. Check the serum potassium level
Correct Answer: A
Rationale: The client is exhibiting severe hypoglycemia with confusion, which impairs
safe swallowing. IV dextrose is the fastest and safest route. Glucagon is an alternative if
IV access is unavailable. Orange juice requires a patent airway and ability to swallow.
Checking potassium is not the priority in this acute situation.
,2. A nurse is teaching a client newly diagnosed with type 2 diabetes about
metformin. Which statement indicates understanding?
A. "I should take this medication only when my blood sugar is high."
B. "I need to watch for signs of low blood sugar with this medication."
C. "I should take this medication with meals to prevent stomach upset."
D. "This medication will replace my need for insulin."
Correct Answer: C
Rationale: Metformin is an oral antihyperglycemic agent that reduces hepatic glucose
production and improves insulin sensitivity. Taking it with meals reduces gastrointestinal
side effects. It does not typically cause hypoglycemia when used alone and is not a
substitute for insulin in type 1 diabetes.
3. A client is prescribed regular insulin and NPH insulin. In which order should the
nurse draw up the medications?
A. Draw up NPH first, then regular.
B. Draw up regular first, then NPH.
C. Mix both without regard to order.
D. Use separate syringes for each.
Correct Answer: B
Rationale: When mixing regular (clear) and NPH (cloudy) insulin, the clear insulin must
be drawn up first to prevent contamination of the regular insulin vial. The mnemonic is
"clear to cloudy."
4. A client with type 1 diabetes is nauseated and vomiting and cannot eat. Blood
glucose is 240 mg/dL. What should the nurse do?
A. Hold the insulin dose until the client can eat.
B. Administer the usual dose of insulin and encourage clear liquids.
C. Administer half the usual insulin dose and call the provider.
D. Instruct the client to check ketones and administer insulin as prescribed.
, Correct Answer: D
Rationale: In illness, insulin needs often increase due to stress hormones. The client
should check ketones and continue insulin as prescribed to prevent DKA. Holding insulin
can lead to hyperglycemia and ketoacidosis.
5. A client with type 1 diabetes is found unresponsive. Which is the priority
nursing action?
A. Check blood glucose.
B. Administer glucagon.
C. Start an IV line.
D. Place the client in a side-lying position.
Correct Answer: A
Rationale: The nurse must first determine the cause of unresponsiveness, which is most
likely hypoglycemia in a type 1 diabetic. Checking blood glucose is the priority before
administering any treatment.
6. A client with diabetes asks how often to exercise to meet goals. What is the
nurse's best response?
A. At least once a week
B. At least three times a week
C. At least five times a week
D. Every day
Correct Answer: B
Rationale: Diabetic clients should exercise at least three times per week to improve
insulin sensitivity and glycemic control.
7. A nurse is teaching a client with diabetes about sick-day rules. Which statement
indicates a need for further teaching?
A. "I will check my blood sugar every 4 hours."
B. "I will continue taking my insulin even if I can't eat."
