pneumatic antishock garment may be helpful Oxygen administration Application of pulse site pressure to avoid bleeding Dopamnie or another inotropic agent used for vigorous fluid resuscitation. Surgery is performed to correct the underlying proble

NURSING MANAGEMENT: Check for airway and adequate circulation. If blood pressure and HR are absent,

start CPR. Record patient’s blood pressure, PR and RR, and peripheral pulses every 15

minutes until the patient’s condition is stabilized. Monitor cardiac rhythm continuously.

Anaphylactic shock - Anaphylaxis is an severe, whole-body allergic reaction. After being exposed to a substance like bee sting venom, the person's immune system becomes sensitized to that allergen. On a later exposure, an allergic reaction may occur. This reaction is sudden, severe, and involves the whole body.

Page 30: Pathophysiology

Hypoglycemia - (abnormally low blood glucose level) occurs when the blood glucose falls to less than 50- 60 mg/dL. It can be caused by too much insulin or oral hypoglycemic agents, too little food, or excessive physical activity. Hypoglycemia may occur at any time of the day or night. It often occurs before meals especially if meals are delayed or snacks are omitted.

EMERGENCY CARE MANAGEMENT:

For patient with severe hypoglycemia (producing confusion or coma), initial treatment is usually I.V administration of a bolus of dextrose 50% solution.

This is followed by continuous infusion of glucose until the patient can eat a meal.

A patient who experience adrenergic reactions without CNS symptoms may receive oral carbohydrates (parenteral therapy isn’t required)

Diagnostic Test:

Glucometer readings 5-hour glucose tolerant test C-peptide assay

Treatment:

Dietary modification Frequent meals Avoid simple carbohydrates Anticholinergic to slow gastric emptying For fasting hypoglycemia, surgery and drug therapy may be required Nondiuretic thiazide (diazoxide) Administer I.V

NURSING MANAGEMENT:

Watch for and report any signs and symptoms of hypoglycemia Implement measure to patient who is unconscious Monitor infusion of hypertonic glucose Measure patient blood glucose with the use of HGT Monitor effect of drug therapy, and watch for development of any adverse

reactions Provide family health teaching

Page 31: Pathophysiology

PATHOPHYSIOLOGY

RISK FACTORS:Too much insulin or oral hypoglycemic agentsToo little foodExcessive exercise

hypoglycemia Blood glucose level drops rapidly

Cells break down fatty and amino acids into adenosine triphosphate (ATP) for energy

Brain cells can’t use ATP for energy

Neuroglycopenia Early glucose deprivation in brain tissue causes mild cerebral dysfunction

CNS symptoms These include headache, dizziness, restlessness, and decreased mental capacity.

AUTONOMIC NERVOUS SYSTEM STIMULATION

Pancreas Sympathetic nerves and epinephrine rapid stimulate glucagons secretions; epinephrine inhibits insulin secretions

Adrenal glands Sympathetic nerves stimulate epinephrine secretions (rapid response). Hypothalamus stimulates pituitary gland to secrete corticotrophin, which acts on the adrenal cortex to cause cortisol secretions (delayed response).

Stomach Hypothalamus stimulates hunger; parasympathetic nerves increase gastric juices contractions.

Liver Sympathetic nerves directly stimulate glycogenolysis; epinephrine, glucagons, cortisol, and growth hormone increase gluconeogenesis; glucagons also stimulates glycogenolysis

Muscle Hypothalamus stimulates pituitary to secrete growth hormone (delayed response), which –along with epinephrine and cotisol-inhibits glucagons use

Adrenergic changes these include hunger, weakness, diaphoresis, tachycardia, pallor, anxiety, and rebound hyperglycemia.
