Jack’s Story Continues

PART A: TYPE II DIABETES MELLITUS (TIIDM)
Before we talk about Jack’s health…
Signs & Symptoms of TIIDM can develop slowly:
10
Central Nervous System (CNS)
Immune
Peripheral Nervous System (PNS)
Other
Type II DM is the result of 2 interrelated problems:
11
Insulin resistance
Insulin receptors are not responding to insulin
How Insulin Works
Insulin is a hormone that comes from the pancreas & regulates how the body uses sugar in the following ways:
12
The Role of Glucose
13
When glucose levels are low, the liver breaks down stored glycogen into glucose
Risk Factors
14
Which of these risk factors apply to Jack?
Weight
Family stress
Race & ethnicity
Blood lipid levels
Fat
Age
Inactivity
Prediabetes
Pregnancy-related risks
Polycystic ovary syndrome
Back to Jack
What affects blood-glucose levels?
Glucose concentration is affected by:
16
Interferences include:

Acute Crisis Situation�
21
Jack has not been in good control of his glucose levels since his wife Mary has been in the hospital. This puts him at risk for:
Characterized by glucose levels >35 mmol/L with NO ketoacidosis
Insulin levels prevent ketosis via lipolysis, but cannot prevent hyperglycemia & osmotic diuresis
FATAL if not treated!
Mortality rate: 10-20%
Hyperosmotic Nonketotic Hyperglycemia (HONK)
Hyperosmotic Hyperglycemic Nonketotic Syndrome (HNNS)
Medlab
Over the last 5 years, Jack has been struggling with pain and numbness in his feet which has affected his ability to maintain his home.
�Jack started doing less and less as time went on due to the pain and numbness.
Jack suffers complications from his TIIDM
Complications & Frequent Comorbidities
23
Autonomic Neuropathy
Eye damage
Kidney disease
Heart & blood vessel disease
Complications & Frequent Comorbidities
24
Peripheral Neuropathy
Neuropathy in limbs
Nerve damage
Which of these complications are present in Jack’s case?
Preventing diabetes
PART B: Diabetic Foot Ulcer
Jack is found by his daughter unkempt, shortness of breath, limping slightly, and has a strange odor coming from him. Jack states he has not been eating or managing his blood sugars & insulin well.
He has not bathed since his wife went to hospital because he is unable to access the bathtub safely. His daughter Nancy, finds an open, oozing wound on Jack’s foot.
Wagner Ulcer Classification System:
The most widely accepted classification system for diabetic foot ulcers and lesions is the Wagner ulcer classification system
Based on
Depth of penetration
Presence of osteomyelitis or gangrene
Extent of tissue necrosis
Nursing
Wagner Ulcer Classification System:
28
5
Extensive gangrenous involvement of the entire foot
4
Gangrene in a portion of forefoot or heel
3
Deeper tissues involved, with abscess, osteomyelitis or tendonitis
2
Deeper ulcer reaching tendon, bone, or joint capsule
1
Superficial ulcer without penetration to deeper layers
0
No open lesions
May have healed lesion
Nursing
Causes of Diabetic Foot Ulcers
29
Poor circulation
Inappropriate footwear
Nerve damage

PART C: Atrial Fibrillation (Afib)
Jack states it feels like his heart is racing and he can’t catch his breath. His Radial pulse is 130 BPM (irregular).
Jack is taken to the emergency department as per his family physician’s recommendation and is diagnosed with new onset of atrial fibrillation.
He is admitted to hospital with a cardiologist and endocrinologist referral.
Complications may arise
36
Complications of Afib
37
Cardiac Conduction
Symptoms for Atrial Fibrillation
38
Which of these symptoms has Jack experienced?
Palpitations, irregular heartbeat
Light-
headedness
Reduced ability to exercise
Chest pain
Fatigue
Dizziness
Shortness of breath
Atrial Fibrillation may be:
39
Occasional
Persistent
Long-standing persistent
Permanent
Possible Causes of Atrial Fibrillation
Which of these risk factors does Jack have?
40
Jack treats his Afib with medication
41
Rate Control Medications | Rhythm Control Medications |
Beta blockers (Metoprolol or Bisoprolol) | Amiodarone (Cordarone) |
Rate Control: Slows the heart rate by blocking some of the incoming electrical signals in the atria and preventing them from being transmitted to the ventricles
Rhythm Control: Maintains sinus rhythm
Jack undergoes procedures for Rhythm Control
42
Electrical Cardioversion
Catheter Ablation
PART D: Heart Failure
When the nurse working the morning shift comes by to see Jack, she notices that there is increased swelling of the ankles, feet and legs and his lower extremities were cool to the touch.
When attempting to wake Jack, the nurse notices that he’s extremely tired and would not open his eyes. Jack responds to her questions in a very slow pace with a sluggish tone. He would further comment to the nurse that he does not know where he is and would like to see his wife.
Heart Failure
What is heart failure?
A condition caused by the heart not functioning as it should or a problem with its structure. It can happen if the heart is too weak or too stiff, or both. This can lead to different comorbidities such as fatigue, swelling in the legs and abdomen and shortness of breath which can be from fluid in the lungs
44
What caused Jack’s Heart Failure?
45
Diabetes
Atrial Fibrillation
Signs & Symptoms
When the heart doesn’t pump well and congestion occurs, the following symptoms may appear:
46
Which of these symptoms does Jack experience?
Increased shortness of breath
Cool extremities
Sudden weight gain
Lethargy
Cough or cold symptoms lasting longer than a week
Cognitive impairment
Change in appetite
Increased urination at night
Increased swelling
Bloating or feeling full all the time
Treating Heart Failure Medications
A combination of medications was administered to Jack:
47
ACE inhibitors
Beta blockers
Diuretics
Nursing
Preventing Heart Failure
Prevention of heart failure mainly lies in lifestyle management
48
Prevention | |
Healthy diet. | Avoiding intake of fatty and salty foods greatly improves the cardiovascular health of an individual |
Cardiovascular exercises | Any activity that will increase heart rate and respiration Vigorous activity raises oxygen and blood flow throughout the body |
Smoking cessation | Nicotine causes vasoconstriction that increases the pressure along the vessels |

PART E: LIVER CANCER
Due to Jack’s history with alcohol, he began to experience abdominal pain and swelling.
At times, when he went to work, his co-workers would point out that his eyes and skin appear yellow. Jack books an appointment with his doctor to find out why he has these symptoms.
During his appointment, the doctor collects information, performs a physical examination and ultrasound along with blood work. Unfortunately, his doctor diagnosed him with grade I malignant liver cancer.
56
Benign vs. Malignant
Benign Neoplasms
Malignant Neoplasms
Pathophysiology
Characteristics of malignant cells:
57
Cells are undifferentiated
Cells grow at periphery and destroy surrounding tissues
Rate of growth is variable
Gain access to the blood and lymphatic channels and metastasizes to other of the body
Often cause anemia, weakness, and weight loss, extensive tissue damage and death

Pathophysiology of Liver Cancer

Carcinogenesis:
Initiation
Promotion
Progression
Invasion & metastasis
What phase is Jack’s liver cancer in?
Tumor Staging & Grading
A complete diagnostic evaluation include identifying the stage and grade of the tumor
Staging: determines tumour size and existence of metastasis
Tumor, nodes, and metastasis (TNM) system
60

M
Jack’s Grade I liver cancer
61
Grading
Grade I - IV
The Role of the Immune system
Immune system
Some evidence indicates that the immune system can detect the development of malignant cells and destroy them before cell growth becomes uncontrolled. If the immune system fails to identify and stop the growth of malignant cells, clinical cancer develops
62
Risk Factors
63
Which of these risk factors does Jack have?
Excessive alcohol consumption
Diabetes
Non-alcoholic fatty liver disease
Jack receives radiation therapy for his cancer
64
Assessment
Assess Jack’s nutritional status, general well-being and skin and oropharyngeal mucosa regularly
Symptoms
Keep an eye out for systemic symptoms
Safety
Assigning Jack to a private room, posting safety precautions, having safety measures for staff and prohibiting/limiting visits to the patient
Jack’s liver was not greatly damaged. His doctor suggested radiation therapy as treatment, since his cancer could not be removed surgically
