Introduction
The endocrine system is a network of glands that produce and release hormones that help control many important body functions, especially the body's ability to change calories into energy that powers cells and organs.
Common endocrine disorders are; - Diabetes ( type 1 or type 2) - Thyroid disorder ( hyperthyroidism or hypothyroidism )

1 .Blood Glucose monitoring
![Page 5: Care of patients with endocrine system disorders Prepared by: Mrs. Alwah Alkathiri Revised by: Dr. Irene Roco Asst. Professor](https://reader036.vdocument.in/reader036/viewer/2022062408/56649ef35503460f94c05195/html5/thumbnails/5.jpg)
Blood glucose Monitoring
• Blood glucose is the amount of glucose in the blood (mmol/L).
• Blood glucose is regulated by insulin and glucagon. • Blood monitoring (BM) is used to indicate when blood
glucose is not within the normal range (4-7mmol/L) ( 70-120 mg/dl) .
• It is used to monitor and manage the treatment of both insulin-dependent diabetes mellitus (IDDM) and non-insulin dependent diabetes mellitus (NIDDM).
![Page 6: Care of patients with endocrine system disorders Prepared by: Mrs. Alwah Alkathiri Revised by: Dr. Irene Roco Asst. Professor](https://reader036.vdocument.in/reader036/viewer/2022062408/56649ef35503460f94c05195/html5/thumbnails/6.jpg)
Goals for BGM• Goal: To maintain blood glucose within target range.
• Immediate benefit:
Identification, treatment, and prevention of high and
low blood glucose levels.
• Long-term benefit:
Decrease risk of long-term complications.
![Page 7: Care of patients with endocrine system disorders Prepared by: Mrs. Alwah Alkathiri Revised by: Dr. Irene Roco Asst. Professor](https://reader036.vdocument.in/reader036/viewer/2022062408/56649ef35503460f94c05195/html5/thumbnails/7.jpg)
Purpose/ Indication of BGM
type 1 and type 2 diabetic patients. unstable diabetes, (hyperglycemia, hypoglycemia, and
diabetic ketoacidosis). For diagnostic purposes of diabetes (signs and symptoms
of polyuria, polydipsia, weight loss of type 1 or weight gain, family history of type 2 .)
Patients taking steroids and other drugs that cause raised blood glucose.
![Page 8: Care of patients with endocrine system disorders Prepared by: Mrs. Alwah Alkathiri Revised by: Dr. Irene Roco Asst. Professor](https://reader036.vdocument.in/reader036/viewer/2022062408/56649ef35503460f94c05195/html5/thumbnails/8.jpg)
Some conditions that may affect the accuracy of blood glucose monitoring (may need a venous sample):
1. Peripheral circulatory failure and severe dehydration e.g., diabetic ketoacidosis, shock, hypotension. These conditions cause peripheral shutdown, which can cause artificially low capillary readings.
2. Some renal dialysis treatments.
3. Hyperlipidemia: cholesterol levels above 13 mmol/L may lead to artificially raised capillary blood glucose readings
4. Pre-eclampsia

TYPE Preparation What it measures PURPOSE
1 .Fasting blood sugar
(FBS)-
NPO for least 8 hours .
measures blood glucose
often the first test done to check for prediabetes and diabetes.
2 .Two (2)-hour postprandial blood sugar
Client eats a meal exactly 2 hours before the blood sample is taken
measures blood glucose exactly 2 hours after having
a meal ;
not used to diagnose diabetes ;
used to check if a diabetic client is taking the right amount of insulin with meals.
3 .Random blood sugar (RBS)
No preparation measures blood glucose regardless of when the client
last ate .
may be taken throughout the day. Blood glucose levels that vary widely may mean a
problem .
Types of Blood Glucose Tests
![Page 10: Care of patients with endocrine system disorders Prepared by: Mrs. Alwah Alkathiri Revised by: Dr. Irene Roco Asst. Professor](https://reader036.vdocument.in/reader036/viewer/2022062408/56649ef35503460f94c05195/html5/thumbnails/10.jpg)
TYPE preparation PURPOSE
4 .Oral glucose tolerance
test -
fasting sample of blood and then taking a very sweet drink containing 75g of glucose.
a series of blood glucose measurements
used to diagnose prediabetes and diabetes, gestational
diabetes .
5 .Hemoglobin A1c, or Glycohemoglo
bin ,
None measures how much sugar (glucose) is stuck to red blood
cells ;
used to diagnose diabetes; shows how well diabetes has been controlled in the past 2 to 3 months and whether diabetic medications needed
to be changed .The result of A1c test can be used to estimate the
average blood sugar level .

Normal and diabetic blood sugar ranges
healthy individuals Diabetics
Before meals : Between 4.0 to 6.0 mmol/L (72 to 108 mg/dL) when fasting
type 1 or type 2 diabetes - 4 to 7 mmol/L
After meals : Up to 7.8 mmol/L (140 mg/dL) 2 hours after eating
type 1 diabetes - under 9 mmol/L type 2 diabetes - under 8.5mmol/L

Route: Subcutaneous
![Page 24: Care of patients with endocrine system disorders Prepared by: Mrs. Alwah Alkathiri Revised by: Dr. Irene Roco Asst. Professor](https://reader036.vdocument.in/reader036/viewer/2022062408/56649ef35503460f94c05195/html5/thumbnails/24.jpg)
When to Give Insulin
• Before meals or snacks.
• For blood glucose levels significantly above target range.
Insulin dose is based on:Blood glucose readings
Age/body weightPhysical activity level .
![Page 25: Care of patients with endocrine system disorders Prepared by: Mrs. Alwah Alkathiri Revised by: Dr. Irene Roco Asst. Professor](https://reader036.vdocument.in/reader036/viewer/2022062408/56649ef35503460f94c05195/html5/thumbnails/25.jpg)
Mixing Insulin 1 .Check the labels on the insulin bottles to make
sure you have the correct insulin. Regular, lispro (Humalog) and aspart (NovoLog). Insulin should be clear. NPH insulin should be cloudy.
2 .Throw away any insulin left in the bottle 30 days after you first open the bottle.
3 .Gently roll the bottle of cloudy insulin between your hands until it is mixed, and there is no powder
on the bottom of the bottle .4 .Do not shake the insulin bottle because this can
cause air bubbles .
![Page 26: Care of patients with endocrine system disorders Prepared by: Mrs. Alwah Alkathiri Revised by: Dr. Irene Roco Asst. Professor](https://reader036.vdocument.in/reader036/viewer/2022062408/56649ef35503460f94c05195/html5/thumbnails/26.jpg)
5 .Aspirate clear Insulin first before the Cloudy Insulin
6 .If you get more units of cloudy insulin in the syringe than are needed, do not push any insulin back into the bottle. Remove the syringe and throw it into your needle disposal box. Get a
new syringe and start over .
