develops more frequently in patients with Type 2 diabetes; often the patient is an older person with an infection or one who has overindulged in carbs, thereby using more insulin than anticipated
condition may be difficult to diagnose initially; severe cellular dehydration results in neurologic deficits, muscle weakness, difficulties with speech, and abnormal reflexes
#1 nursing intervention with a patient who has HHNC is:
maintain a patent airway!
hyperglycemia and dehydration develop because of the relative insulin deficit, but sufficient insulin is available to prevent ketoacidosis

afterload, hypertension
will lead to an increase in CO and maintenance of tissue perfusion
indicative of angina pectoris; condition in which the heart has outgrown its blood supply
an increase in the muscle mass and cardiac wall thickness in response to overwork and strain; occurs slowly because it takes time for increased muscle tissues to develop; generally follows persistent or chronic dilation and thus further increases the contractile power of the muscle fibers

immune system
all immune cells originate here
bone marrow
activate the immune system to produce matching antibodies
antigens
the first line of defense that blocks entry of materials or harmful substances
skin/mucous membranes
a fracture complication that may occur as local pain and irritation cause strong muscle contractions at the fracture site; pulls the bone fragments further out of position, causing angulation, rotation of a bone, or overriding of the bone pieces
muscle spasm
a complication that develops in a limb following treatment as edema increases during the first 48 hours after the trauma and casting; if peripheral area becomes pale or cold and numb or pulse decreases or is absent, it is likely that the cast has become too tight and is compromising the circulation in the limb
ischemia
may develop shortly after the fracture occurs when there is more extensive inflammation, such as with crash injuries; increase pressure of fluid within the fascia, (non-elastic covering of the muscle) compresses nerves and vessels, causing severe pain and ischemia or necrosis of the muscle; pressure effects may be aggravated by a cast
compartment syndrome
are a risk when fatty marrow escapes from the bone marrow into a vein within the first week after injury.

-usually originate as upper respiratory infections, middle ear infections, or "strep throat", certain strains of staph are occasionally responsible for initiating the immune disorder in the kidney
-usually develops 10 days to 2 weeks after the antecedent infection; usually affects children between ages of 3 and 7, especially boys
-facial and periorbital edema occur initially, followed by generalized edema as colloid osmotic pressure of blood drops and sodium and water are retained
-leads to elevated blood pressure and edema
-antistreptococcal antibodies create an antigen-antibody complex that lodges in the glomerular capillaries, activates the compliment system to cause an inflammatory response in the glomeruli of both kidneys
glomerulonephritis
-filtrate travels through this and electrolytes and water are adjusted to the body's current needs
-furosemide acts on this to decrease reabsorption of sodium and water
-reabsorption of Na+ and Cl- in ascending limb; reabsorption of water in descending loop; concentration of filtrate
Loop of Henle
-can be acute or chronic, acute referring to a single episode, chronic referring to the long-term condition
-onset commonly occurs in children and some patients are no longer subject to attacks after adolescence
-bronchi and bronchioles respond to the stimuli with three changes, inflammation of the mucosa with edema, contraction of smooth muscle, and increased secretion of thick mucus in the passages
asthma
-involves acute episodes triggered by a Type 1 hypersensitivity reaction to an inhaled antigen
-in patients with this, the antigen reacts with immunoglobulin E on the previously sensitized mast cells in the respiratory mucosa, releasing histamine, kinins, prostaglandins, and other chemical mediators, which cause inflammation, bronchospasm, edema, and increased mucus secretion; also stimulates branches of the vagus nerve, causing reflex bronchoconstriction
extrinsic asthma
onset occurs during adulthood; in this disease other types of stimuli target hyper-responsive tissues in the airway, initiating the acute attack (respiratory infections, exposure to cold, exercise, drugs such as aspirin, stress, and inhalation or irritants such as cigarette smoke)
intrinsic asthma
occurs a few hours later after an asthma attack in which leukocytes are increased, particularly eosinophils, releasing additional chemical mediators such as leukotrienes, resulting in prolonged inflammation, bronchoconstriction and epithelial damage
second stage
the destruction of the alveolar walls and septae, which leads to large, permanently inflated alveolar air spaces
in some, there is a genetic deficiency of alpha1- antitrypsin, a protein that normally presents in tissues and body fluids that inhibits the activity of proteases, which are destructive enzymes released by neutrophils during an inflammatory response
lungs appear to have many large holes in them (blebs or bullae)
onset is insidious and dyspnea occurs first on exertion and then progresses until it is marked even at rest; hyperventilation with a prolonged expiratory phase, use of accessory muscles, and hyperinflation leading to development of a "barrel chest"; anorexia and fatigue contributing to weight loss; clubbed fingers and secondary polycythemia may develop as compensations

A. bradycardia.
B. decreased heart contractility.
C. increased skeletal muscle blood supply.
D. hyperglycemia.
D. hyperglycemia.
It will cause transient hyperglycemia. The epinephrine will increase heart rate and contractility. There will be increased venous return to the heart and, thus, increased cardiac output and blood pressure. Epinephrine dilates blood vessels of the muscles.
hyperglycemia
a process of wound healing that occurs when there is minimal tissue damage, damaged cells recover, and the tissues return to normal within a short period of time (ex: after a mild sunburn)
resolution
wound healing that occurs in damaged tissue in which the cells are capable of mitosis; some types of cells are constantly replicating, here as other cells such as hepatocytes in the liver are able to undergo mitosis when necessary; damaged tissue is thus replaced by identical tissue from the proliferation of nearby cells
regeneration
refers to the process involved when the would is clean, free of foreign material and necrotic tissue, and the edges of it are held close together, creating a minimal gap between the edges; seen in some surgical incisions
first intention healing
refers to a situation in which there is a large break in the tissue and consequently more inflammation, a longer healing period, and formation of more scar tissue; a compound fracture would heal in this manner
second intention
exophthalmos
occurs in hyperthyroidism and with Grave's disease
evident by the presence of protruding, staring eyes and decreased blink and eye movements; results from increased tissue mass in the orbit pushing the eyeball forward and from increased sympathetic stimulation affecting the eyelids; if untreated, visual impairment may result from optic nerve damage or corneal ulceration
type of infiltrative ophthalmopathy that is due to impaired venous drainage from the orbit, which causes increased fat deposits and edema in the retroorbital tissues; forcing the eyeballs outward
exophthalmos occurs in hyperthyroidism as a result of ____ accumulation in eye and ____ tissue
fluid/retroorbital tissue
first and most important step in stopping Laennec's syndrome
stop drinking!
goal treatment is to correct the underlying cause and to replace both water and any needed electrolytes
volume deficit
balanced IV solutions such as lactated ringer's solution are usually given and isotonic sodium chloride is used when rapid replacement is needed
fluid volume deficit
results from a loss of function, partial or total, of one or more components of the immune system leading to increased risk of infection and cancer
immunodeficiency
involve a basic developmental failure somewhere in the system (Ex: in the bone marrow's production of stem cells) the thymus, or the synthesis of antibodies
primary deficiencies
refers to loss of immune response resulting from specific causes and may occur at any time during the lifespan
secondary immunodeficiency (acquired)
patients on dialysis have an increased risk of infection by this
HIV
used to treat HIV
antiretroviral agents
releases ammonia
urease
ammonia
an end product of protein metabolism in the liver or intestine, and then is converted by liver cells into urea for excretion by the kidneys
a nitrogen waste resulting from protein metabolism in the intestine or liver, is removed from the blood and converted to urea, enabling it to be excreted by the kidneys
correlates well with the signs of hepatic encephalopathy
used to check kidney and liver functions
conversion of ammonia typically occurs here
elevation of this can result in hepatic encephalopathy secondary to liver cirrhosis
