NURSES ROLE IN DISASTERS

Disaster preparedness, response, and recovery Mass casualty triage, helping to ensure patients get the most appropriate level of care Putting disaster response plans into action Evacuation Decontamination NURSES MAY ALSO BECOME LEADERS AS THEIR COMMUNITIES PREPARE FOR POTENTIAL DISASTERS BY CREATING OR REVISING EMERGENCY PREPAREDNESS AND CONTINGENCY PLANS

Three goals for hospital decontamination

: 1) Hospitals must not allow contaminated patients to enter the facility, if the patient cannot be decontaminated at the on-incident scene a decontamination site should be set up just outside of ED 2) hospitals should decontaminate patients as rapidly as possible 3) hospitals must plan to protect the decontamination team from secondary exposure and injury.

Pathophysiology of the emergent/resuscitative phase

Burn injury occurs and increases blood flow to area and a release of vasoactive substances occurs, which then increase capillary permeability. Water, sodium, plasma proteins shift to interstitial and surrounding tissues. Decreased intravascular volume occurs which can cause BURN shock. Patients can have insensible losses (evaporation) of up to 400ml/hr Electrolyte/fluid imbalance occur decreased sodium, increased potassium and increased hematocrit Iv fluids have to be administered to restore capillary permeability and prevent shock

Complications of the emergent phase

Burn shock (COMBO OF DISTRIBUTIVE AND HYPOVOLEMIC SHOCK)- CAN OCCUR SECONDARY TO massive fluid shift, continues until capillary integrity restored (within 24-36 hours of the injury) Treat with fluid replacement Vasoconstriction Dysrhythmias Intravascular hypovolemia and edema results in necrosis this can cause (Circulation impairment) Compartment syndrome

If the patient is breathing <30/minute and has normal perfusion but is unconscious or can't follow your commands, tag RED. If your breathing, normally perfused victim can follow commands, tag YELLOW if they can't get up or GREEN if they can.

The nursing student asks the nurse how central diabetes insipidus (DI) is different from nephrogenic DI. How should the nurse respond? Central DI occurs because the kidneys are resistant to ADH. Central DI is caused by decreased secretion of ADH. Central DI is observed in patients with chronic renal insufficiency. Central DI occurs when the kidneys are unable to concentrate urine.

Central DI is caused by decreased secretion of ADH.

RPMs Perfusion:

Check for a radial pulse and/or capillary refill. If no radial pulse or it takes longer than 2 seconds for nail bed color to return to pink, tag RED. If a pulse is present and CRT is normal, move to mental status.

Clinical manifestations of addisons

Decreased cortisol (can't stimulate gluconeogenesis and fat synthesis) → low BG, weakness, weight loss, fatigue, nausea, abdominal pain, gastroenteritis, and emotional lability. Decreased aldosterone (can't reabsorb NA or excrete K)→ leads to water loss, dehydration and hypotension. ACTH increases (related to MSH) → hyperpigmentation of the skin and mucous membranes Androgen & estrogen decreased → decreased pubic and axillary hair.

Destruction of the cells of the hypothalamus lead to the condition. Traditional craniotomy is the reason for this. Head trauma often causes the condition.

Destruction of the cells of the hypothalamus lead to the condition.

Wound management

Dressing Wounds: use of antimicrobial such as silvadene Open: wound remains open to the air, covered only by topical antimicrobial agent. Allows easy access to wound, it also increase the risk for hypothermia. closed: a topical antimicrobial agent is applied and wound is covered with gauze and wrapped with roll bandage.

hyperparathyroidism

Excess PTH (hypercalcemia & hypophosphatemia)

Syndrome of Inappropriate Antidiuretic Hormone (SIADH)

Excessive amount of ADH → kidney reabsorbs too much H2O → decreases urine output (urine concentrated) → water overload → hemodilution (hyponatremia, decreased serum osmolality, decreased hematocrit).

Adrenal Cortex Hyperfunction

Excessive circulating glucocorticoid (cortisol) is the pathophysiologic process associated with primary hypercortisolism. Additionally, excessive secretion of ACTH from anterior pituitary leads to hypercortisolism.

Pathophysiology of hyperparathyroidism

High PTH levels → osteoclasts release calcium from bones into the blood (hypercalcemia and weak bones). PTH also causes intestine absorb more calcium from food, adding to the excess calcium in the blood. Due to high blood calcium levels, the kidneys excrete more calcium in the urine, which can lead to kidney stones.

Pathophysiology of adrenocortical insufficiency

Related to a decrease in one of the following: Glucocorticoid (cortisol) & mineralcorticoid (aldosterone) (primary insufficiency/ Addison's/adrenal cortex) ACTH (secondary insufficiency/ant pituitary) CRH (tertiary insufficiency/hypothalamus)

Management of Diabetes Insipidus

Replace Fluids: P.O. water Hypotonic IV fluids if unable to take p.o. (D5W) Monitor for hyperglycemia, volume overload and slowly decreasing the serum sodium Replace ADH: Desmopressin (DDAVP) or Vasopressin (Pitressin) - synthetic ADH (SQ, IN, or oral). Monitor U/O, serum electrolytes, fluid status (skin turgor, cap refill, daily weight)

Medical Management of Addisons

Replacement of cortisol IV hydrocortisone sodium succinate (Solu-Cortef) 50 to 100 mg (contains both glucocorticoid/cortisol and mineralcorticoid/aldosterone). If chronic, will need a corticosteroid (replaces cortisol) like prednisone, and a mineralcorticoid (replaces aldosterone) like fludrocortisone/Florinef. Fluid replacement IVFs with glucose Monitor frequently VS LOC Labs (sodium, glucose and potassium) If hyperkalemic Potassium binding or excreting agents (Kayexalate) If hypotension persists Vasopressors (dopamine)

Rehabilitative Stage Burns

Restorative, may overlap with acute stage and continues after discharge, as early as 2 weeks or up to 7-8 months Begins with wound closure and ends when patient returns to highest level of restoration Goals are to achieve maximal function, have psychological adjustment, and gain independence Due to new tissue growth needs rom is needed to prevent contractures, keep body parts extended

Adrenocortical Insufficiency (ADDISONS)

Results from destruction of adrenals (primary insufficiency), decreases ACTH from anterior pituitary (secondary insufficiency) or dysfunction of hypothalamus (tertiary insufficiency) Most common among females 30 to 50 years old

Serum and urine electrolytes Osmolality Urine-specific gravity

Diagnostics of Addison's disease

Serum cortisol levels (collected in a.m. d/t dec during day) Low with <5 mcg/dL with disease (normally 5-25 mcg/dL). Serum electrolytes affected: Hyponatremia (<135 mEq/L) d/t low aldosterone. Hyperkalemia (>5.0 mEq/L) d/t low aldosterone. Hypoglycemia (<60 mg/dL) d/t low cortisol Imaging studies: CT/MRI - to assess size and morphology of adrenal glands.

What is main concern for patient in addisonian crisis

Shock

What is the basis of fluid therapy replacement for the treatment of diabetes insipidus? Serum osmolality is decreased as fluids are replaced rapidly. A fluid challenge is used to restore fluid volume. Additional fluids are needed in the intravascular space to maintain adequate fluid volume. Slowly decreasing the serum sodium decreases rapid correction of hypernatremia

Slowly decreasing the serum sodium decreases rapid correction of hypernatremia

pituitary gland

The endocrine system's most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands.

Pathophysiology of Hypoparathyroidism

The low production of PTH results in hypocalcaemia (accompanied by hypomagnesemia)and hyperphosphatemia. Calcium plays a major role in appropriate muscle contraction. In low amounts it can lead to muscular rigidity and if severe tetany which can result in laryngospasm. (trach tray at bedside after thyroidectomy)

Which is true regarding the pituitary gland? Select all that apply. The pituitary gland is located in the sella turcica. The anterior pituitary gland secretes prolactin. The posterior pituitary gland synthesizes oxytocin. The posterior pituitary gland is responsible for the The anterior lobe of the pituitary is called adenohypophysis.
