Working in a chemical plant would increase the risk for chemical burns.

A nurse is completing her annual cardiopulmonary resuscitation training. The class instructor tells her that a client has fallen off a ladder and is lying on his back; he is unconscious and isn't breathing. What maneuver should the nurse use to open his airway? A. Neck tilt-head lift B. Jaw-thrust C. Abdominal thrust D. Seldinger

B. Jaw-thrust If a neck or spine injury is suspected, the jaw-thrust maneuver should be used to open the client's airway. To perform this maneuver, the nurse should position herself at the client's head and rest her thumbs on his lower jaw, near the corners of his mouth. She should then grasp the angles of his lower jaw with her fingers and lift the jaw forward. The head tilt-chin lift maneuver is used to open the airway when a neck or spine injury isn't suspected.

A nurse is providing care to an older adult client who has frostbite of the feet. Which action would be least appropriate? A. Providing an analgesic for pain B. Massaging the feet C. Restricting ambulation D. Placing sterile cotton between the toes after rewarming

A crying teenager who is holding pressure on an arm laceration C. A young woman who appears dazed and confused and is shivering D. A screaming middle-aged woman looking frantically for her husband

C. A young woman who appears dazed and confused and is shivering The young woman is demonstrating classic signs of shock, possibly from a closed head injury. Initial management of a client displaying signs of shock includes management of airway, breathing, and circulation. Initial treatment includes keeping the client warm. Oxygenation and intravenous fluids will be needed immediately to stabilize and maintain tissue perfusion. A first responder would be unlikely to be able to release a foot trapped under wreckage without help. The teenager is already applying pressure to the arm and is more likely to be able to maintain self-care until help arrives.

The nurse from a medical unit is called to assist with care for clients coming into the hospital emergency department during an external disaster. Using principles of triage during a disaster, the nurse should attend to the client with which problem first? A. Fractured tibia B. Penetrating abdominal injury C. Bright red bleeding from a neck wound D. Open massive head injury in deep coma

C. Bright red bleeding from a neck wound The client with arterial bleeding from a neck wound is in immediate need of treatment to save the client's life. This client is classified as such and would wear a color tag of red from the triage process. The client with a penetrating abdominal injury would be tagged yellow and classified as "delayed," requiring intervention within 30 to 60 minutes. A green or "minimal" designation would be given to the client with a fractured tibia, who requires intervention but who can provide self-care if needed. A designation of "expectant" is applied to the client with massive head or other injuries and minimal chance of survival; the corresponding color code is black in the triage process. Such clients receive supportive care and pain management but are given definitive treatment last.

The nurse is caring for a victim of a chemical disaster. Medications given in the treatment of this client include amyl nitrite, sodium nitrite, and sodium thiosulphate. What chemical agent does the nurse know this client has been exposed to? A. Sarin B. Mustard gas C. Cyanide D. Anthrax

C. Cyanide Cyanide poisoning calls for the administration of one or all of the following antidotes: amyl nitrite, sodium nitrite, and sodium thiosulfate. Amyl nitrite promotes the formation of methemoglobin, which combines with cyanide to form nontoxic cyanmethemoglobin. Sarin, mustard gas, and anthrax are not treated in this way.

An older victim who is sitting next to her husband sobbing, "My husband is dead. My husband is dead."

B. A woman who is complaining, "My leg is bleeding so bad, I am afraid it is going to fall off!" Priority nursing care in disaster situations needs to be delivered to the living and not the dead. The victim who is bleeding badly is the priority. The bleeding could be from an arterial vessel; if the bleeding is not stopped, the victim is at risk for shock and death. The pregnant client is the next priority, but the absence of fetal movement may or may not be indicative of fetal demise.

The emergency department (ED) nurse receives a telephone call and is informed that a tornado has hit a local residential area and that numerous casualties have occurred. The victims will be brought to the ED. The nurse should take which initial action? A. Prepare the triage rooms. B. Activate the emergency response plan. C. Obtain additional supplies from the central supply department. D. Obtain additional nursing staff to assist in treating the casualties.

B. Activate the emergency response plan.

The nurse received a patient from a motor vehicle accident who is hemorrhaging from a femoral wound. What is the initial nursing action for the control of the hemorrhage? A. Apply a tourniquet. B. Apply firm pressure over the involved area or artery. C. Elevate the injured part. D. Immobilize the area to control blood loss.

B. Apply firm pressure over the involved area or artery. A tourniquet is applied to an extremity only as a last resort when the external hemorrhage cannot be controlled in any other way and immediate surgery is not feasible.

A female patient was sexually assaulted when leaving work. When assisting with the physical examination, what nursing interventions should be provided? (Select all that apply.) A. Have the patient shower or wash the perineal area before the examination. B. Assess and document any bruises and lacerations. C. Record a history of the event, using the patient's own words. D. Label all torn or bloody clothes and place each item in a separate brown bag so that any evidence can be given to the police. E. Ensure that the police are present when the examination is performed.

B. Assess and document any bruises and lacerations. C. Record a history of the event, using the patient's own words. D. Label all torn or bloody clothes and place each item in a separate brown bag so that any evidence can be given to the police. A history is obtained only if the patient has not already talked to a police officer, social worker, or crisis intervention worker. The patient should not be asked to repeat the history. Any history of the event that is obtained should be recorded in the patient's own words. The patient is asked whether he or she has bathed, douched, brushed his or her teeth, changed clothes, urinated, or defecated since the attack, because these actions may alter interpretation of subsequent findings. Each item of clothing is placed in a separate paper bag. The bags are labeled and given to appropriate law enforcement authorities. The patient is examined (from head to toe) for injuries, especially injuries to the head, neck, breasts, thighs, back, and buttocks. The exam focuses on external evidence of trauma (bruises, contusions, lacerations, stab wounds).

nerve agent

hyperstim of nerve endings sarin, soman organophosphates tx: supportive care and atropine bc it blocks acetylcholine decontaminate: copious amounts of soap and water or saline for at least 20 min blot down wipe plastic equipment will absorb sarin gas

carbon monoxide poisoning

inhaled CO2 bind to hemoglobin and does not transfer oxygen pulse ox looks high but its not s/s: CNS s/s predominate skin color and pulse ox not reliable s/s tx: fresh air immediately, CPR, administer O2 100% monitory continuously

vesicants

chemical causes blistering results in burning, bronchitis and death - 24 hours post exposure - stinging and vesicles appear sulfur mustard, nitrogen muistard respiratory issues decontamination: soap and water, do not scrub or use hypochlorite solutions eye exposure requires copious irritation

wounds cleaning primary closure delayed closure

cleaning: most with NS, clip hair dont shave primary closure: suturing subcut fat, brought together and closure of epidermis, skin edges level and possible use of butterfly stitches delayed closure: pt has a significant tissue loss or at high risk for infection, place gauze over wound, make sure its splinted to prevent movement

radiation exposure

decontamination no necessary not a medical emergency radioactive gases, liquids or solide require immediate medical attention to prevent incorporation - uptake of radioactive material into body

pulmonary agents

destroy pulmonary membrane

ER triage

level 1, resuscitation: assess continuously, ex: code/post code, seizure, hemorrhaging; one on one level 2, emergent: assess Q15 min, ex: code stroke, MI postictal level 3, urgent: assess Q30 min, ex: HTN, bleeding wound, fever, funky vs, appendicitis level 4, less urgent: assess Q1 hr, CHF, laceration, ash,a, someone who went to urgent care instead of ER level 5, non urgent: assess Q2 hr, can have PCP manage at later time, ex: ear infection, food poisoning, episodic illness thats easily controlled airway, hemorrhage, hypovolemic shock, wounds, trauma/multiple trauma

personal protective equipment

level A: highest level, self controlled breathing apparatus, vapor tight chemical resistance suit, gloves and boots; highest level hazmat level B: high level respiratory protection, but less skin and eye protectant, and chemical resistant suit; high level hazmat level C: air purified respirator, overall with splash hood, chemical resistant gloves and boots, typically ready in hospital level D: standard precautions

psychiatric emergency

management: maintain safety of all persons and gain control of situation , determine risk of injury, maintain self esteem while caring, determine if there's psych history safety is #1

patients with poisoning

most important: what, when and how s/s of particular poison: call poison control, they will tell you antidote supportive care to maintain all vital organs age and wt for poison control gastric lavage only effective with in 1 hr activated charcoal: most poison besides corrosive, its black thick and messy possibly dieresis or dialysis snake bite antivenom: with in 4 hrs, Favbar and Crofab; type of snake will determine which dose, dry expensive provide warmth, immobilize extremity, no ice measure and assess circumference every 15 min find out the type of snake - certain ones have proteins that affect neuro status, cardiac and RR s/s: localized edema, localized ecchymosis, necrosis of site, N/V, possible metallic taste in mouth lie down and remove clothing

tympanic rupture

most sensitive organ to rupture s/s: hearing loss, tinnitus, dizziness, pain

crush injury complications

rabdo from severe muscle damage hypovolemic shock: movement of blood and plasma into injury once object is removed; ex: pt in a disaster and tree fell on leg, or pinned against wall with chair paralysis of body part, erythema and blistering, damage to body part renal dysfunction: prolong hypotension * dont move object, it will cause more damage

heat stroke s/s interventions complications at risk

s/s: CNS dysfunction, increased temp, hoy dry skin, tachypnea, hypotension, tachycardia, increased O2 demands interventions: cool sheets, cold water, reduce fire temp quickly (over 1 hr), stop at 38 or 104 degree to prevent hypothermia monitor: temp, VS, EKG, LOC, UOP, CVP, IVF ice to groin, neck, chest, axillae, lavage to stomach or colon, bath complications: administer IVF slowly due to high risk of MI or renal issues at risk: older adults, younger, chronic illness, people taking certain meds

intra abdominal injury s/s priorities complications

s/s: abd. bleed: abd, very hard, tympanic blunt injury: difficult to determine exact injury, muscle rigidity, tenderness, swelling of extremities, pain bowel sound hypoactive priority: hold oral fluids, assess other areas accompanying abd. injuries, may need NG tube, prophylactic antibiotic, assess referred pain (spleen, liver, intraperitoneal injury), exploratory surgery, immobilize spine, continuously monitor ct for bleeding labs: ABG, H&H, lactic complications: hemorrhage, gun shot can cause more damage to hollow organs, if viscera (internal organs) are protruding then cover with sterile moist saline dressing

hemorrhage s/s priorities internal vs external

s/s: loss of volume, loss of cardiac output, loss of tissue perfusion numbness, tingling, changes in vision, blood in stool, urine, vomit etc., chest pain, HA, LOC, weakness, seizures s/s shock: cool, clammy, rapid pulse, rapid breathing, N/V priorities: stop bleeding and monitor for s/s of shock fluids: LR then NS, packed RBC, platelets internal: shock VS: tachycardia, hypotension, change in skin, color, pale, weak, fatigue external: tourniquet and pressure, if tourniquet in the filed write time placed bc of perfusion if bleeding is severe then possible rapid transfuser

chemical burns

severity depends on chemical and amount and mechanism tx: immediately flush skin with running water from shower hose or faucet, determine substance, some require prolonged flushing or irrigation white phosphorus should be brushed off not washed off follow up is reexamined at 24 hr, 72 hour and 7 days

smallpox

spread by direct contact, droplet, very contagious s/s: fever, fatigue, HA, rash contagious after rash appears supportive care and antibiotics cremation preferred: virus lives in scabs up to 13 years
