1 YEAR NURSING PROGRAM

SUMMER 2008 HNI 364


The story of patient s s

The story of patient S.S.

Case Study: Diabetes Mellitus


Who is s s case history
Who is S.S.?: Case History

  • White female, 5’ tall, 87 lbs.

  • Active, thin 14 year-old

  • General good health, occasional cold/flu

  • Never been hospitalized

  • Family history: maternal grandmother has hyperthyroidism


History of present illness hpi
History of Present Illness (HPI)

  • Late fall, Mrs. S. noticed that S.S. was pale and less active

  • S.S. felt tired and began to avoid friends and activities (wanted to resign from cheerleading!)

  • S.S. was constantly hungry, but still thin.

  • S.S. noticed she had to use the bathroom after almost every class.

  • S.S. was irritable, had difficulty concentrating

  • Due to these symptoms, Mrs. S. took S.S. to family physicians


S s s current status
S.S.’s current status

  • S.S. has lost 7 lbs in last week, despite eating 5-6 meals /day.

  • Skin is pale and dry

  • VS are within normal limits, but respirations and ulse rates are higher than on previous physical exams.

  • Voiding lg. amounts of urine q 1-2 hrs

  • Constantly hungry, thirsty, fatigued

  • Fasting glucose level = 396 mg/dl

  • Urine acetone +



Conclusions
Conclusions regulate her insulin!

  • S.S. and her family demonstrated technical competence and understanding in:

    • Blood glucose monitoring

    • Urine testing

    • Diet activity

    • Sick day management

    • Reason for urine testing


S s released from hospital
S.S. released from hospital!! regulate her insulin!


Question 1a

Question 1A: regulate her insulin!

What was the most likely cause of S.S.’s polyuria and weight loss before her hospitalization?


No insulin formed regulate her insulin!

by pancreas

Diabetes Type 1

Accumulation of glucose

in bloodstream

(Hyperglycemia)

No uptake of glucose

by body’s cells

Increased solute concentration in

blood due to excess glucose

Polyuria

H20 moves from high

to low solute concentration:

from cells to intravascular space

Body excretes excess

H20, glucose, and

electrolytes in urine

Cell dehydration


Why did s s lose weight
Why did S.S. lose weight? regulate her insulin!

When your body cannot utilize glucose for energy it will begin to breakdown adipose tissue or fat and use that for energy, which explains the weight loss.


Question 1b

Question 1B: regulate her insulin!

What are normal blood glucose levels?


Normal blood glucose
Normal blood glucose regulate her insulin!

Normal blood glucose levels, before meals, should be less than 100 mg/l.

Normal blood glucose levels, 2 hours after meals, should be less than 140 mg/l.

Realistic target levels for people on medication is 70 – 140 before meals and less than 180 after meals.


Question 2

Question 2: regulate her insulin!

Compare and contrast the signs and symptoms of diabetic ketoacidosis and insulin shock. Explain why each occurs.


The differences between ketoacidosis insulin shock

The regulate her insulin!DIFFERENCES betweenketoacidosis &insulin shock


Lab tests
Lab tests regulate her insulin!

Ketoacidosis

High blood glucose levels (> 250 mg/dL)

Accumulation of ketones in urine and blood

Insulin shock

Low blood glucose levels (< 45 mg/dL)


Symptoms
Symptoms regulate her insulin!

Ketoacidosis

Extreme thirst

Dehydration

Dry mouth

Frequent urination

Fatigue

Nausea/Vomiting

Difficulty breathing

Difficulty concentrating

Insulin shock

Confusion

Difficulty concentrating

Irritability

Weakness

Tremors

Anxiety

Hunger


Hyperglycemia regulate her insulin!


What s the deal with ketoacidosis
What’s the deal with ketoacidosis? regulate her insulin!

When the body cannot use glucose for energy due to the lack of insulin, the glucose is converted into fat for energy.

Excess fat is broken down by the liver and produces ketone bodies, which end up in the urine (ketouria).

Polyuria further increases the concentration of ketone bodies in the urine.

Breakdown of protein in the body also produces ketone bodies, contributing to ketoacidosis.


What causes insulin shock
What causes insulin shock? regulate her insulin!

Too much insulin in the blood due to overdose during an insulin shot.

Since insulin is responsible for uptake of glucose into body’s cells, too much insulin results in too little blood glucose.

Immediate intake of sugar will counteract insulin shock.


Similarities between ketoacidosis insulin shock
Similarities between regulate her insulin!ketoacidosis & insulin shock

Both ketoacidosis and insulin shock are severe, emergency situations.

If left unaddressed they can both lead to coma.

The best way to prevent either one is to constantly monitor blood glucose levels.


Question 3 regulate her insulin!: Why must insulin be injected? Discuss the various types of insulin, their time of onset, peak of action and duration of action. Do persons with Type II diabetes ever require insulin injections? If so, when and why?


Why must insulin be injected
Why must insulin be injected? regulate her insulin!

  • Insulin is a protein made up of two peptide chains linked together by disulfide bonds.

  • Proteins are broken down and digested by proteases (i.e. pepsin in the stomach & trypsin in the small intestines)

  • If taken orally, insulin will therefore be broken down and deactivated, never reaching the blood stream

  • Insulin must be injected SQ to provide a more direct route of entry into the blood stream


Types of insulin
Types of Insulin regulate her insulin!

  • Rapid (Quick-acting)

    -Insulin Lispro

  • Short Acting

    -Regular (R)

  • Intermediate-Acting

Do persons with type ii diabetes ever require insulin injections if so when why
Do persons with Type II Diabetes ever require insulin injections? If so, when & why?

  • Type II diabetes occurs when the body produces enough insulin, but the ability to process & use this insulin is lost (the body becomes resistant)


Type II Diabetes Insulin Requirements injections? If so, when & why?

Injections of insulin should mimic normal release patterns of the body

Long-acting insulin is usually injected 1-2x a day

In addition, short-acting or rapid-acting insulin is injected at mealtimes


Question 4 goal for a nutrition program for children with type 1 diabetes
Question #4 injections? If so, when & why?Goal for a nutrition program for children with Type 1 Diabetes

  • Maintain blood glucose levels without causing excessive hypoglycemia

  • When hypoglycemia occurs bring levels up to 80 mg/dl

  • Foods low on glycemic index do not produce drastic changes in blood glucose levels; i.e. whole grains, oranges and peanuts


  • DIET: injections? If so, when & why?

    - > 50% calories from carbohydrates (1300 kcal/day)

    - 10-15% calories from protein (260-390 kcal/day)

    - 30-35% calories from fats (780-910 kcal/day)


Tips to help when eating out
Tips to help when eating out injections? If so, when & why?

  • keep a count of calorie intake

  • eat slowly

  • eat same portions as you would at home

  • order foods that are not breaded or fried

  • choose healthy alternatives

  • carry diabetes kit with you.

  • if rapid acting insulin is taken, try to delay injection until meal is served

  • talk to doctor about how to adjust insulin regimen when eating out


5a how do you prepare the injection why

#5A How do you prepare the injection? Why? injections? If so, when & why?

•NPH (intermediate-acting) and regular (shortacting) are commonly mixed to produce differently-timed pharmacologic actions with a single injection.

•The regular insulin is prepared

first to prevent it from becoming contaminated with the intermediate-acting insulin (NPH).


Steps to preparing injection
Steps To Preparing Injection injections? If so, when & why?

  • •Carefully verify insulin labels.

  • •Roll the NPH vial between hands to resuspend the insulin preparation.

  • •If vial did not have cap on top, wipe off with an alcohol swab.

  • •Verify dosage a second time.

  • •Check the patient's name, medication, dosage, route and time of administration.


    Steps to preparing injection cont
    Steps To Preparing Injection (Cont.) injections? If so, when & why?

    •With the same syringe inject air equal to the dose of insulin to be withdrawn from the short-acting (regular) insulin.

    • Take insulin syringe and aspirate volume of air equivalent to the dose of insulin to be withdrawn from the intermediate-acting (NPH) insulin first.

    • DO NOT LET THE TIP OF NEEDLE TOUCH THE INSULIN.

    • Remove syringe from vial without aspirating the insulin.


    Steps to preparing injection cont1
    Steps To Preparing Injection (Cont.) injections? If so, when & why?

    • Withdraw the correct dose into the syringe (10 units of regular). Verify again that the correct dose has been withdrawn.

    • Place the needle of the syringe back into the NPH vial and withdraw the correct dose (10 units). Verify that the correct dose has been withdrawn.

    • The total amount of insulin in the syringe should be the sum of the two types (20 units).

    • Because short acting insulin was mixed with

      intermediate-acting insulin, which reduces

      the action of the faster-acting insulin, administer

      the mixture within 5 minutes of preparation.


    What type of syringe would you use
    What Type of Syringe would you use? injections? If so, when & why?

    Since the total amount to be given is 20 units, a low dose 50 unit syringe is appropriate, but a 100 unit syringe may also be used.

    • A 50 or 100 unit Insulin syringe would be used

    • Insulin is measured in units (check the insulin bottle)

      * syringe measuring cc's or mL's cannot be used*


    What sites could you use for the injection
    What sites could you use for the injection? injections? If so, when & why?

    • Insulin should be administered subcutaneously

    • There are 4 main sites:

      abdomen, posterior arms, anterior and lateral thighs and posterior hips

    • The insulin is absorbed faster in the abdomen and the rate of absorption decreases in the arms, thighs and hips


    Education
    Education injections? If so, when & why?

    Teach the patient what treatments are used, how the treatments work and how to administer the drugs

    The patient should be aware of the effects of continuously injecting into the same site

    They should know that it is important to rotate the injection site

    They shouldn’t inject into a limb that is to be exercised because it will be absorbed faster and may result in hypoglycemia.


    Question #5: injections? If so, when & why?Lipodystrophy and What are some of the long term complications of diabetes and why do they occur?

    Researchers: J Strasheim & M. Valerio

    Lipodystrophy: injections? If so, when & why?Localized Disturbance of Fat Metabolism Below Skin Surface

    Causes: Not Rotating Insulin Injection Sites

    2 Forms:

    • Lipoatrophy

    • Lipohypertrophy


    Lipoatrophy loss of subcutaneous fat under the skin surface resulting in small dents
    Lipoatrophy: injections? If so, when & why?Loss of Subcutaneous Fat Under the Skin Surface Resulting in Small Dents

    • Appears as Slight Dimpling

    • Appears as Pitting (more serious)


    Lip hypertrophy buildup of fat below the skin surface causing lumps
    Lip hypertrophy: injections? If so, when & why?Buildup of Fat Below the Skin Surface Causing lumps

    • Appears as Fibro-Fatty Masses.

    • Absorption is Delayed at these Sites.

    • Avoid these Sites Until Hypertrophy Disappears.

    Creating your

    sick-day plan


    Diabetes management can be especially challenging when you're struggling with a cold or other illness.


    Proper planning can help you prevent complications. you're struggling with a cold or other illness.


    You don't feel well. Your temperature is high, you're tired and you've lost your appetite.

    Having diabetes only adds to your concerns.


    When you're sick, your body produces hormones to help fight the illness.

    These hormones raise your blood sugar by preventing insulin from working effectively.

    In people without diabetes, the additional sugar promotes healing.

    But when you have diabetes, the fluctuations can result in potentially serious diabetes complications.


    To prevent complications, the illness.

    make a sick-day plan

    part of your diabetes

    management.


    Start with your health care team
    Start with your health care team the illness.

    Talk to your doctor and other members of your diabetes care team about your sick-day plan.

    Make sure your sick-day plan includes:

    What medications to take

    How often to measure your blood sugar and urine ketones

    How to adjust your insulin dosage, if you need insulin

    How to manage any other conditions you may have

    When to call your doctor

    Also identify a loved one or friend who can contact your doctor or help you seek emergency care if you experience diabetes complications.


    Keep close track of your blood sugar and urine ketone levels
    Keep close track of your blood sugar and urine ketone levels the illness. :

    Continue taking your diabetes medication when you're sick, and remember to test your blood sugar often. You may need to adjust your insulin doses or other medications. Here are some general guidelines:

    Type 1 diabetes. Check your blood sugar and urine ketone levels every four hours.

    Excessively high blood sugar can lead to ketoacidosis, especially in people who have type 1 diabetes.  e conditions can be fatal.


    Excessively high blood sugar can lead to ketoacidosis, especially in people who have type 1 diabetes.  

    These conditions can be fatal.


    Stick to your diabetes meal plan
    Stick to your diabetes meal plan especially in people who have

    With a minor illness such as a cold, you may be able to stick to your diabetes meal plan — which will help ensure blood sugar stability. Remember to check the sugar content of any over-the-counter medications you take. Many cough syrups and other liquid cold preparations are high in sugar.


    If you have nausea, vomiting or diarrhea, you may not be able to eat your regular foods. But it's still important to get enough carbohydrates. Try these foods, which contain about 10 to 15 grams of carbohydrates each:1 double-stick frozen fruit pop

    1 cup milk

    1/2 cup fruit juice

    1/2 cup regular (not diet) soda

    6 saltine crackers

    3 graham crackers

    1 slice dry toast

    1/2 cup regular (not artificially sweetened) gelatin


    In addition to sipping fruit juice or sweetened beverages, drink at least 8 ounces of water or other calorie-free liquid every hour you're awake.

    If you're not able to keep anything down, it's especially important to monitor your blood sugar closely.


    Know when to contact your doctor
    Know when to contact your doctor drink at least 8 ounces of water or other calorie-free liquid every hour you're awake.

    Diabetes complications can quickly become dangerous.

    Contact your doctor if:

    Your blood sugar level is higher than 300 mg/dL

    Your blood sugar level is higher than 240 mg/dL for more than 24 hours

    Your urine ketone level is moderate to high

    You feel sleepier than usual or can't think clearly

    You're unable to keep fluids down or vomit for more than six hours

    You have diarrhea for more than six hours

    You feel confused and can't think clearly

    Your lips and tongue appear dry and cracked


    Think prevention
    Think prevention drink at least 8 ounces of water or other calorie-free liquid every hour you're awake.

    High blood sugar can weaken your immune system. This makes you more likely to get a cold or the flu — and more vulnerable to serious effects of common illnesses. To reduce the risk of getting sick, wash your hands often and avoid crowds during flu season.


    Think prevention1
    Think prevention drink at least 8 ounces of water or other calorie-free liquid every hour you're awake.

    Ask your doctor about

    vaccination for flu

    and

    pneumococcal pneumonia.


    If you do get sick, drink at least 8 ounces of water or other calorie-free liquid every hour you're awake.

    feel confident in your ability

    to manage your diabetes by following

    your sick-day plan.


    Infections
    Infections drink at least 8 ounces of water or other calorie-free liquid every hour you're awake.

    Respiratory Infections

    People with diabetes face a higher risk for influenza and its complications, including pneumonia, possibly because the disorder neutralizes the effects of protective proteins on the surface of the lungs. In fact, deaths among people with diabetes increase by 5 - 15% during flu epidemics, and they are six times more likely to be hospitalized with complications from flu than non-diabetic patients who have flu. Everyone with diabetes should have annual influenza vaccinations and a vaccination against pneumococcal pneumonia.


    Infections1
    Infections drink at least 8 ounces of water or other calorie-free liquid every hour you're awake.

    Urinary Tract Infections

    Women with diabetes face a significantly higher risk for urinary tract infections, which are likely to be more complicated and difficult to treat than in the general population.
