first degree frostbite

Type of frostbite called frostnip and this only affects the surface skin, which is frozen. On onset there is itching and pain, and then the skin develops white, red, and yellow patches and becomes numb. The area affected by frostnip usually does not become permanently damaged as only the skin's top layers are affected. Long-term sensitivity to both heat and cold can sometimes happen after suffering from frostnip.

third and fourth degree frostbite

Type of frostbite where the muscles, tendons, blood vessels, and nerves all freeze. The skin is hard, feels waxy, and use of the area is lost temporarily, and in severe cases, permanently. The deep frostbite results in areas of purplish blisters which turn black and which are generally blood-filled. Nerve damage in the area can result in a loss of feeling. This extreme frostbite may result in fingers and toes being amputated if the area becomes infected with gangrene. If the frostbite has gone on untreated they may fall off. The extent of the damage done to the area by the freezing process of the frostbite may take several months to assess, and this often delays surgery to remove the dead tissue.

second degree frostbite

Type of frostbite where the skin may freeze and harden, but the deep tissues are not affected and remain soft and normal. Second-degree injury usually blisters 1-2 days after becoming frozen. The blisters may become hard and blackened, but usually appear worse than they are. Most of the injuries heal in one month but the area may become permanently insensitive to both heat and cold.

Peritoneal lavage

________ _______ is a test used to determine the presence or absence of internal bleeding within the abdomen. Injury to the abdomen can result from blunt forces (i.e. motor vehicle accidents) and from penetrating objects (knife wounds and bullets). Determining the significance of an internal injury can often be based on the results from this test. This test is performed by introducing a long, flexible plastic tube into the abdomen. A small incision is made adjacent to the naval using a local anesthetic. The tube is advanced to a certain depth into the abdomen so that fluid can be aspirated with a syringe. The presence of blood in the aspirate confirms significant injury that will require surgery. If the aspirate is free of blood, fluid (salt water solution) will be delivered through the tube into the abdominal cavity. It will then be allowed to flow back out for microscopic analysis.

When is back pain considered chronic?

when pain lasts for more than 3 months

Hypothermia

when tem drops below 96.2 at this point tissue damage and ischemia may result. Drowsiness may occur as respirations, heart rate and body processes occur.

Neurogenic Shock

when there is trauma or malfunction to the nervous system. Most frequently know as spinal shock. ex vehicle crashes. s/s Fluid loss, bleeding, burns, fluid and electrolyte imbalances related to excessive diarrhea or vomiting or sepsis from trauma or injury. Very Pale (clammy) ex Burns S/S Skin Warm and dry Hypotension Oliguria decreased urine Heart Rade decreases Tachypnea LOC Modified trendelenburg

The triage nurse in the EC unit must be able to explain

why clients with non-urgent problems must wait without making them feel that they do not deserve health care.

What are generalized seizures?

wide-spread excessive electrical discharge, involves both hemispheres; may be tonic, atonic, myoclonic, absence

What does an organized physical assessment start?

with a mental statis

20/20

What are some risk factors for MS?

young (20-40), higher above the 37th parallel, more in caucasians and higher socioeconomic class

Possible etiologies of seizures related to metabolic disturbances

• Acidosis • Electrolyte imbalances • Hypoglycemia • Hypoxia • Alcohol or barbiturate withdrawal • Dehydration or water intoxication

Nursing Diagnoses for patients with migraines:

• Acute pain • Anxiety • Hopelessness

Complications of Seizures

• Are considered a neurologic emergency • Can involve any type of seizure • The brain uses more energy than supplied • Neurons become exhausted and cease to function • Permanent brain damage can result

Fatigue

• Aspiration precautions • Mouth care and moisture for lips • Altered routes of medication administration if needed—choose the least invasive route of medication administration with the most effective treatment ...are all things to do for managing what?

Phases of a seizure: Aural

• Aural phase with sensory warning

Generalized seizures

• Characterized by bilateral synchronous epileptic discharges in the brain from seizure onset • Keep accurate notes to describe!!! • No warning or aura as entire brain is affected • Loss of consciousness from seconds to minutes

• Myoclonic seizure

• Characterized by sudden, excessive jerk of body and extremities • Can be forceful enough to cause fall • Brief and may occur in clusters • Keep accurate notes to describe!!!

Psychosensory symptoms that may occur during complex partial seizure include:

• Distortions of visual or auditory sensations • Vertigo • Alterations in memory • Alterations in thought processes

Phases of a seizure: Ictal

• Ictal phase with full seizure

Lumbar Puncture

• Insertion of spinal needle into the subarachnoid space (between the third and fourth lumbar vertebrae) • Contraindicated in clients with increased intracranial pressure • Empty bladder • Position: Patient should bend over. May have in fetal position on bed or hunched over a table • Spinal headache possible from spinal tap

Clinical manifestations in patients during EOLC

• Lethargy with long periods of sleep • Difficulty in communication • Distress • Constipation • Cold, mottled, cyanotic skin • Decreased BP, heart rate, respiratory rate The above are all examples of what?

• Tonic-clonic status epilepticus

• Most dangerous because it can cause: -Ventilatory Insufficiency---Provide oxygen!! -Hypoxemia--Provide oxygen!!! -Cardiac Arrhythmias -Hyperthermia -Systemic Acidosis • Trauma during seizures can cause severe injury and death

* Migraine without aura involves at least one of the following

• Nausea and vomiting • Photophobia and phonophobia

Benign Cells

• Normal cells - wrong place or wrong time • Look like tissues they come from • ENCAPSULATED • Do not migrate • Are euploid & small nucleus

• Typical absence seizures (petit mal)

• Occurs only in children and rarely into adolescence • May cease or develop into another type • Typical symptom is staring spell for only a few seconds and usually goes unnoticed • Brief loss of consciousness • May occur up to 100 times/day if untreated • EEG demonstrates pattern unique to this type of seizure • Often precipitated by hyperventilation and flashing lights

Primary drugs for treatment of generalized tonic-clonic and partial seizures:

• Older: Dilantin, Tegretol, Phenobarbital, and Depakote • Newer: Neurontin, Lamictal, Topamax, Gabitril, Keppra, and Zonegram

Partial seizures (Not Generalized anymore)

• Partial seizures referred to as partial focal seizures • Begin in a specific region of the cortex • May be confined to one side of the brain and remain partial or focal in nature • May involve entire the brain, cumulating in tonic-clonic seizure

Phases of a seizure: Postictal

• Postictal phase with rest and recovery

Phases of a seizure: Prodromal

• Prodromal phase precedes seizure with signs or activity

Nervous system changes associated with aging:

• Recent memory loss • Decreased touch sensation • Change in perception of pain • Change in sleep patterns • Altered balance and/or decreased coordination

Migraine Headache

• Recurring • Characterized by unilateral or bilateral throbbing pain • Triggering event or factor • Family history • Women affected more often than men

What types of generalized seizures exist?

• Tonic-clonic seizures (grand mal) • Typical absence seizures (petit mal) • Atypical absence seizures • Myoclonic seizure • Akinetic, atonic, and astatic are used interchangeably for drop attacks

Migraine without aura involves at least two of these characteristics:

• Unilateral location • Pulsating quality • Moderate-to-severe intensity • Worsening with activity
