Endocrine & Hematologic Emergencies Flashcards
Define
Diabetes Mellitus
A disorder of glucose metabolism, such that the body has an impaired
ability to get glucose into the cells to be used for energy.
Glucose cannot get into the cell, the cell goes unfed, and the level
of glucose in the blood remains high and continues to rise
Insulin allows glucose to ____
Enter and nourish the cells
issa key
Define
Type 1 Diabetes
an autoimmune disorder in which the individuals immune system produces antibodies against the pancreatic beta
cells
Without the insulin from the pancreatic beta cells, the patient must
obtain insulin from an external source
Signs & symptoms
Type 1
Polturia, Polydipsia, Polyphagia, AMS, body aches
Define
Diabetic Keto-Acidosis
The bodys cells do not receive enough gluccose for energy, the body begins to burn fat
Textbook says:
A form of hyperglycemia in uncontrolled diabetes in which certain acids accumulate when insulin is not available.
What is Ketones?
Acid Waste
Signs & Symptoms
Diabetic Keto-Acidosis
Define
Type 2 Diabetes
caused by resistance to the effects of insulin at the
cellular level
There are typically fewer insulin receptors.This leads to increase of BS
This developes later in life. Based on a unhealthy lifestyle. Insulin resistance
Signs & symptoms
Type 2 diabetes
Recurrent infection, change in vision, or numbness in the feet, weakness, drowsiness
Define
hyperosmolar hyperglycemic nonketotic syndrome (HHNS)
In type 2, hyperglycemia leads to a state of dehydration due to the discharge of fluids from all body systems and eventually out through the
kidneys, leading to a much more ominous situation of fluid imbalance
Signs & Symptoms
hyperosmolar hyperglycemic nonketotic syndrome (HHNS)
Hyperglycemia
Altered mental status, drowsiness, lethargy
Severe dehydration, thirst, dark urine
Visual or sensory deficits
Partial paralysis or muscle weakness
Seizures
the patient may become
unconscious or have seizure activity due in part to the severe
dehydration that results.
Name the 3 types of hematology emergencies
- Sickle Cell
- Hemophillia A
- Thrombophillia
True or false
People with sickle cell often experience hypoxia
True
Define
Hemophilia
A decreased ability to create a clot after an injury
How long does it take a healthy person to form a blood clot after injury?
13 seconds after a small cut &
no longer than 7 minutes following a more serious injury
Define
Thrombophilia
clotting more than normal
a disorder in the body’s ability to maintain the
viscosity and smooth flow of blood through the venous and arterial
systems.
Define
Deep Vein Thrombosis
(DVT)
Clots that form deep in the veins, usually the legs
a common medical problem in
sedentary patients and in patients who have had recent injury or
surgery
Define
Acidosis
The buildup of excess acid in the blood or body tissues that can result from a primary illness.
Define
Hyperosmolar Hyperglycemic Nonketotic Syndrome
(HHNS)
A lifethreatening condition resulting from high blood glucose that typically occurs in older adults and which causes altered mental status, dehydration, and organ damage.
What primary illnesses cause Metabolic Acidosis?
too much acid production or loss of bicarbonate
- DKA
- Lactic Acidosis
- Severe Sepsis
- Shock
- Severe Heart failure
- Severe trama
- Prolonged seizures
- Renal failure
- severe dehydration
What primary illnesses cause Respiratory Acidosis?
lungs cant remove enough carbon dioxide
- COPD
- Severe Asthma attack
- Pneumonia
- Pulmonary Edema
- Upper Airway Obstruction
- Stroke
- Head Injury
- Overdose
- Neuromuscular diseases
Define
Kussmaul Respirarion
Deep, rapid breathing; usually the result of an accumulation of certain acids when insulin is not available in the body.
Define
Polydipsia
Excessive thirst that persists for long periods despite reasonable fluid intake; often the result of excessive urination
Define
Polyphagia
Excessive eating; in diabetes, the inability to use glucose properly can cause a sense of hunger.
