Questions and Answers on Diabetes

Group of diseases that result in too much sugar in the blood. Diabetes is a chronic condition that affects the way the body processes sugar. It is a multi- system disease. Diabetes mellitus can be referred to as metabolic disorder known as hyperglycemia. This happen due to lack of insulin. High glucose levels, if not controlled will damage nerves and blood vessels. This will lead to decreased sensation and poor circulation. It usually affects lower extremities and sometimes can lead to diabetic foot ulcers with diabetic patients.

Types of Diabetes:

Type 2 Diabetes: A chronic condition that affects the way the body processes blood sugar.

Type 1 Diabetes. A chronic condition in which the pancreas produces little or no insulin. These patients have to depend on insulin.(Insulin dependent)


1.A newly diagnosed diabetes patient is admitted for evaluation and treatment. The patient receives a SubQ injection for regular insulin at 07am.

When does the insulin peak?

Answer: 11AM

Rationale: Short acting can be given subQ,onset 1/2 to 1hour,peak 2- 4hours,duration 5- 7hours.

Signs and symptoms of hyperglycemia. Hypotension, headache, drowsiness, weakness, stupor coma, tachycardia .Skin warm, and dry ,mucous membranes, elevated temperature, polyuria,oligaria, polydipsia ,dyspagia,kussmaul respiration (Rapid and Deep),fruity of breath ,and high blood sugar


Irritability, confusion, tremors, blurry vision, coma, seizures normal BP,tachycardia, normal respiration, skin cool and clammy, diaphoresis, normal urine output.

3.While making rounds, the nurse finds an unconscious insulin dependent diabetic. The nurse performs an assessment and finds the patient diaphoretic with cool and clammy skin. Vital signs are BP 100/60,Pulse 110,respiration 20,temperature 97.6,02 sat room air 93°F. The first action the nurse should take is to:


A.Prepare for the administration of dextrose 50% intravenously. Blood sugar monitoring Q4hours, later give complex carbohydrate and protein.

A.Arterial blood gas has no coloration.

B.This is normal for type 1 DM.

C.Increased production and decreased utilization of ketones bodies. Diabetic ketoacidosis.

D.None of the above exist.

Correct answer A.

Rationale: Dehydration corrected volume restored, improving skin tugor,weight gain, hematocrit drops to normal.Intravaneous iv fluid and insulin will correct it, and patient place on diabetic diet.

A.Check blood sugar and urine specific gravity

B.Check blood sugar Q6hours for hyperglycemia.

C.Check urine specific gravity for osmotic diuresis.

None of the above is correct.

D.Correct answer B.

Rationale: Having reduced her diet and insulin, she should monitor blood sugar frequently.

9.The nurse plan of care for a patient receiving Total Parental Nutrition (TPN)What will the nurse check most frequently?


A.Knowledge deficit related to lack of education about diabetes mellitus.

B.Ineffective coping mechanism about the disease.
