A client is being cared for in the ED. The client is assigned to the triage category of "urgent." How often must the nurse reassess the client?

Every 30 minutes Explanation: Clients assigned to the resuscitation category must receive continuous nursing surveillance, those in the emergent category must be reassessed at least every 15 minutes, clients in the urgent category must be reassessed at least every 30 minutes, those in the less urgent category must be reassessed at least every 60 minutes, and those in the nonurgent category must be reassessed at least every 120 minutes.

A patient who has accidentally ingested toilet bowel cleaner is brought to the emergency department. Which action would NOT be appropriate for the nurse to implement?

Induced vomiting Explanation: Vomiting is never induced after ingestion of caustic substances (acid or alkaline) such as toilet bowl cleaner because the substance is corrosive to the tissues. Appropriate actions include dilution with milk or water, gastric lavage, and administration of activated charcoal.

A nurse is providing care to an older adult client who has frostbite of the feet. Which action would be least appropriate?

Massaging the feet Explanation: For a client with frostbite, massaging the affected body part is contraindicated. Analgesia is given for pain during the rewarming process because it can be very painful. Ambulation would be restricted. Once rewarmed, sterile gauze or cotton is placed between the affected toes to prevent maceration.

Which of the following statements would most lead a nurse to suspect that a patient is experiencing food poisoning?

"My brother got sick like me after eating the same food." Explanation: The statement about the patient's brother also being sick after eating the same food suggests food poisoning. Feeling sick to the stomach for 3 to 4 days could indicate various problems, not just food poisoning. Food tasting or looking fine does not really indicate anything definitive about the patient's condition. Most foods causing bacterial poisoning do not have unusual odor or taste. A pain in the left groin area is more suggestive of appendicitis, not food poisoning.

The nurse is administering antivenin to a patient who was bitten on the arm by a poisonous snake. What intervention provided by the nurse is required prior to the procedure and every 15 minutes after?

Measure the circumference of the arm. Explanation: Before administering antivenin and every 15 minutes thereafter, the circumference of the affected part is measured. Premedication with diphenhydramine (Benadryl) or cimetidine (Tagamet) may be indicated, because these antihistamines may decrease the allergic response to antivenin. Antivenin is administered as an IV infusion whenever possible, although intramuscular administration can be used.

Acetaminophen overdose is treated with administration of which medication?

N-acetylcysteine Explanation: Treatment of acetaminophen overdose includes administration of N-acetylcysteine. Flumazenil is administered in the treatment of nonbarbiturate sedative overdoses. Naloxone is administered in the treatment of narcotic overdoses. Diazepam may be administered to treat uncontrolled hyperactivity in the client with a hallucinogen overdose.

A client present to the ED following a work-related injury to the left hand. The client has an avulsion of the left ring finger. Which correctly describes an avulsion?

Tissue tearing away from supporting structures Explanation: An avulsion is described as a tearing away of tissue from supporting structures. A laceration is a skin tear with irregular edges and vein bridging. Abrasion is denuded skin. A cut is an incision of the skin with well-defined edges, usually long rather than deep.

A client arrives at the emergency department and is experiencing a severe allergic reacton to a bee sting. The client received treatment and is being discharged. Which client statement indicates that additional teaching about exposure prevention is needed?

"Brightly colored clothes help to ward off bees." Explanation: To prevent insect stings, the client should avoid wearing brightly colored clothing because it attracts bees. The client should wear covering on the feet and avoid going barefoot because yellow jackets nest and pollinate on the ground. Staying still or motionless reduces the likelihood of being stung. Perfumes and scented soaps attract bees and should be avoided.

The nurse is caring for a client in the ED following a sexual assault. The client is hysterical and crying. The client states, "I know I'm pregnant now, maybe I have HIV. Why did this happen to me?" Which is the best response by the nurse?

"Let's talk about this. Do you want me to call a support person?" Explanation: The client should be reassured that anxiety is natural and asked whether a support person may be called. The goals of management are to provide support, reduce the client's emotional trauma, and gather available evidence for possible legal proceedings. Throughout the client's stay in the ED, the client's privacy and sensitivity must be respected. The client may exhibit a wide range of emotional reactions, such as hysteria, stoicism, or feelings of being overwhelmed. Support and caring are crucial.

The nurse is conducting a secondary survey on a client in the ED. Which action is completed during the secondary survey?

Diagnostic and laboratory testing Explanation: Diagnostic and laboratory testing is completed during the secondary survey, along with a complete health history, a head-to-toe assessment, insertion or application of monitoring devices, splinting of suspected fractures, cleansing, closure, and dressing of wounds, and performance of other necessary interventions based on the client's condition. The other interventions are completed during the primary survey.

A patient brought to the ED by the rescue squad after getting off a plane at the airport is complaining of severe joint pain, numbness, and an inability to move the arms. The patient was on a diving vacation and went for a last dive this morning before flying home. What is a priority action by the nurse?

Ensure a patent airway and that the patient is receiving 100% oxygen. Explanation: Decompression sickness, also known as "the bends," occurs in patients who have engaged in diving (lake/ocean diving), high-altitude flying, or flying in commercial aircraft within 24 hours after diving. Signs and symptoms include joint or extremity pain, numbness, hypesthesia, and loss of range of motion. A patent airway and adequate ventilation are established before all other interventions, as described previously, and 100% oxygen is administered throughout treatment and transport.

Which triage category refers to life-threatening or potentially life-threatening injury or illness requiring immediate treatment?

Explanation: The client triaged as emergent must be seen immediately. The triage category of urgent refers to minor illness or injury needing first-aid-level treatment. The triage category of immediate refers to nonacute, non-life-threatening injury or illness.

After inserting an oropharyngeal airway, which of the following indicates that the airway is properly positioned?

Flange is at the client's lips. Explanation: An oropharyngeal airway is properly positioned when the distal end is in the hypopharynx and the flange is approximately at the client's lips. Air moving through the airway may or may not indicate proper placement. An oropharyngeal airway is inserted so that the tongue is displaced anteriorly.

Which phase of the psychological reaction to rape is characterized by fear and flashbacks?

Heightened anxiety phase Explanation: During the heightened anxiety phase, the client demonstrates anxiety, hyperalertness, and psychosomatic reactions, in addition to fear and flashbacks. The acute disorganization phase is characterized by shock, disbelief, guilt, humiliation, and anger. The denial phase is characterized by an unwillingness to talk. The reorganization phase occurs when the incident is put into perspective. Some clients never fully recover from rape trauma.

A client comes to the emergency department with a suspected airway obstruction. The emergency department team prepares to manage the client as if he has a complete airway obstruction based on which of the following?

High-pitched noise on inhalation Explanation: A client who demonstrates a weak, ineffective cough, high-pitched noise while inhaling, increased respiratory difficulty, or cyanosis should be managed as if he or she has a complete airway obstruction. Forceful coughing, wheezing between coughs, and a refusal to lie flat suggest a partial airway obstruction that can be managed as such.

A nurse is caring for a client who has arrived at the emergency department in shock. The nurse intervenes based on the knowledge that which of the following is the most common cause of shock?

Hypovolemia Explanation: Types of shock include cardiogenic, neurogenic, anaphylactic, and septic. Of these, the most common cause is hypovolemia

A client suffering from carbon monoxide poisoning would exhibit which manifestation?

Intoxication Explanation: A client suffering from carbon monoxide poisoning appears intoxicated (from cerebral hypoxia). Other signs and symptoms include headache, muscular weakness, palpitation, dizziness, and mental confusion. The skin coloring in the client with carbon monoxide poisoning can range from pink to cherry red to cyanotic and pale and is not a reliable diagnostic sign.

Which solution should the nurse use to replace lost fluids in a client with signs and symptoms of shock due ot hemmorhaging?

Lactated Ringer solution Explanation: Replacement fluids may include isotonic electrolyte solutions( lactated Ringers, nomoral saline) ,colloids, and blood component therapy. O negative blood is prepared for emergency use in women of childbearing age. Dextrose 5% in water should not be used to replace fluids in hypovolemic clients. Hypertonic saline is used only to treat severe symptomatic hyponatremia and should be used only in intensive care units.

A patient arrives at the emergency department after sustaining a gunshot wound to the abdomen. When assessing the patient, the nurse pays particular attention to which of the following?

Liver Explanation: Penetrating abdominal injuries, such as from a gunshot wound, are serious and result in a high incidence of injury to hollow and solid organs. Although any organs can be injured, the liver is the most frequently injured solid organ. The small bowel is a frequently injured hollow organ. Thus, of the options shown, the nurse would assess the liver area most closely.

Which solid organ is most frequently injured in a penetrating trauma?

Liver Explanation: The most frequently injured solid organ in a penetrating trauma is the liver because of its size and anterior placement in the right upper quadrant of the abdomen.

When preparing to perform abdominal thrusts on a client with an airway obstruction, which of the following would be most appropriate?

Positioning the hands in the midline slightly above the umbilicus Explanation: When performing abdominal thrusts, the nurse would place the thumb side of one fist against the client's abdomen in the midline slighlty above the umbilicus and well below the xiphoid process, grasping the fist with the other hand. Then the nurse would press the fist into the client's abdomen with a quick inward and upward thrust such that each new thrust should be a separate and distinct maneuver. The unconscious client is positioned on the back. The client who is conscious should be standing or sitting.

Which guideline is appropriate for a nurse to implement while helping family members cope with the sudden death of a loved one?

Show acceptance of the body by touching it, giving the family permission to touch. Explanation: The nurse should encourage the family to view and touch the body if they wish, since this action helps the family to integrate the loss. The nurse should avoid using euphemisms such as "passed on." The nurse should avoid giving sedation to family members, because this may mask or delay the grieving process. The nurse should avoid volunteering unnecessary information (e.g., client was drinking at the time of the accident).

A client comes to the emergency department after experiencing a wound. Inspection reveals an opening in the skin with distinct edges and whose depth is greater than the length of the wound. The nurse documents this as which type of wound?

Stab Explanation: A stab wound is an incision of the skin with well-defined edges and is typically deeper than long. It is usually caused by a sharp instrument. A laceration is a tear in the skin with irregular edges and vein bridging. An avulsion is manifested as a tearing away of tissue from the supporting structures. A patterned wound takes on the outline of the object causing the wound.

A client is admitted to the emergency department after sustaining a penetrating injury to the abdomen. Which of the following would the nurse identify as a possible cause?

Stabbing with a knife Explanation: Penetrating abdominal injuries are ones involving an opening into the abdomen, such as those that occur with a gunshot or stabbing. Blunt injuries usually occur with motor vehicle crashes, falls, and explosions.

A patient was bitten by a tick 3 months ago and is now having muscle aches as well as joint pain and swelling. The patient is having difficulty with self care and requires assistance with activities of daily living (ADLs). What stage of Lyme disease does the nurse recognize the patient is in?

Stage III Explanation: Lyme disease has three stages. Stage I presents with a classic "bull's-eye" rash (i.e., erythema migrans) and flulike signs and symptoms that may include chills, fever, myalgia, fatigue, and headache. If antibiotics are not administered, stage II Lyme disease may present within 4 to 10 weeks following the tick bite and may manifest with joint pain, memory loss, poor motor coordination, and meningitis. Stage III can begin anywhere from weeks to more than a year after the bite and has serious long-term chronic sequelae, including arthritis, neuropathy, myalgia, and myocarditis.

A nurse is providing inservice education for staff members about evidence collection after sexual assault. The educational session is successful when staff members focus their initial care on which step?

Supporting the client's emotional status Explanation: The teaching session is successful when staff members focus first on supporting the client's emotional status. Next, staff members should gain consent to perform the pelvic examination, perform the examination, and collect evidence, such as semen if present.

What is a common source of airway obstruction in an unconscious client?

The tongue Explanation: In an unconscious client, the muscles controlling the tongue commonly relax, causing the tongue to obstruct the airway. When this situation occurs, the nurse should use the head-tilt, chin-lift maneuver to cause the tongue to fall back into place. If she suspects the client has a neck injury she must perform the jaw-thrust maneuver.

A nurse is preparing to assist with a gastric lavage for a client who has ingested an unknown poison and is obtunded. To ensure that the tube reaches the stomach, the nurse would measure the distance from the bridge of the nose to which of the following?

Xiphoid process Explanation: The nurse measures the tube from the bridge of the nose to the xiphoid process to ensure that the tube reaches the stomach on insertion.

The nurse is caring for a client in the ED with frostbite to the left hand. During the rewarming process of the hand, the nurse should perform which action?

Administer analgesic medications as ordered. Explanation: During rewarming, an analgesic for pain is administered as prescribed because the rewarming process may be very painful. Frozen extremities are usually placed in a 37°C to 40°C (98.6°F to 104°F) circulating bath for 30- to 40-minute spans. This treatment is repeated until circulation is effectively restored. Hemorrhagic blebs, which may develop 1 hour to a few days after rewarming, are left intact and unruptured. Nonhemorrhagic blisters are debrided to decrease the inflammatory mediators found in the blister fluid. After rewarming, hourly active motion of any affected digits is encouraged to promote maximal restoration of function and to prevent contractures.

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?

Apply firm pressure over the involved area or artery. Explanation: Direct, firm pressure is applied over the bleeding area or the involved artery at a site that is proximal to the wound (Fig. 72-3). Most bleeding can be stopped or at least controlled by application of direct pressure. Otherwise, unchecked arterial bleeding results in death. A firm pressure dressing is applied, and the injured part is elevated to stop venous and capillary bleeding, if possible. If the injured area is an extremity, the extremity is immobilized to control blood loss. 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 40-year-old client is admitted to the ED with facial bruises and a broken right wrist. Upon further assessment, the nurse notes multiple bruises in various stages of healing. Which is the best course of action by the nurse?

Asking the client whether they are experiencing abuse Explanation: The priority is to ask the client whether they are experiencing abuse, then proceed as the situation dictates. Nurses must be mindful that competent adults are free to accept or refuse the help that is offered to them. Some clients insist on remaining in the home environment where the abuse or neglect is occurring. The wishes of clients who are competent and not cognitively impaired should be respected. However, all possible alternatives, available resources, and safety plans should be explored with the client. Mandatory reporting laws in most states require health care workers to report suspected child abuse or abuse of older adults to an official agency, usually Adult (or Child) Protective Services. All that is required for reporting is the suspicion of abuse; the health care worker is not required to prove abuse or neglect.

A homeless client presents to the ED. Upon assessment, the client is experiencing hypothermia. The nurse will plan to complete which priority intervention during the rewarming process?

Attach a cardiac monitor Explanation: Continuous electrocardiograph (ECG) monitoring is performed during the rewarming process because cold-induced myocardial irritability leads to conduction disturbances, especially ventricular fibrillation. A urinary catheter should be inserted to monitor urinary output; however, ECG monitoring is the priority. There is no indication for endotracheal intubation. Inotropic medications are contraindicated because they can stimulate the heart and increase the risk for fatal dysrhythmias, such as ventricular fibrillation.

A client with a history of allergies comes to the emergency department. The nurse suspects anaphylaxis based on which of the following? Select all that apply.

Chest tightness Localized itching Pallor Facial angioedema Explanation: Manifestations suggesting anaphylaxis include chest tightness, generalized itching, pallor, massive facial angioedema, tachycardia or bradycardia, and decreasing blood pressure (as a result of peripheral vascular collapse).

The nurse is discussing measures about how to prevent Lyme disease with a client and his family. Which of the following would the nurse include?

Don a hat, pulling any long hair back so it doesn't come in contact with shrubs. Explanation: To prevent Lyme disease, wear a hat and pull long hair back so that it does not brush against shrubs or other vegetation; wear light-colored clothing to increase tick visibility; wear long-sleeved shirts and long pants (tuck pants into socks or boots); and erect fences to keep deer away from houses and gardens.

A patient is brought to the emergency department and diagnosed with decompression sickness. The nurse interprets this as indicating that the patient most likely has been involved with which of the following?

Diving in an ocean Explanation: Decompression sickness occurs when patients have engaged in diving in a lake or ocean or high-altitude flying or flying in a commercial aircraft within 24 hours of diving. Swimming in a lake could lead to a near-drowing episode. Running a race in hot humid weather would increase a person's risk for heat stroke. 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?

Jaw-thrust Explanation: 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. To perform this maneuver the nurse places two fingers on the chin and lifts while pushing down on the forehead with the other hand. The abdominal thrust is used to relieve severe or complete airway obstruction caused by a foreign body. The Seldinger maneuver is a method of percutaneous introduction of a catheter into a vessel.

A nurse is providing an in-service program for fellow emergency nurses about hypothermia and rewarming methods used. The nurse determines that the presentation was successful when the group identifies which of the following as a passive active rewarming method?

Over-the-bed heaters Explanation: Passive active rewarming uses over-the-bed heaters to the extremities and increases blood flow to the acidotic, anaerobic extremities. Cardiopulmonary bypass and warm humidified oxygen by ventilator are examples of active core (internal) rewarming methods. Forced warm air blankets are examples of active external rewarming methods.

A nurse is providing an educational program for a group of occupational health nurses working in chemical facilities. Which of the following would the nurse include as the priority in the case of a chemical burn?

Rinsing the area with copious amounts of water Explanation: The priority for any chemical burn is to immediately drench the area with running water, unless the chemical is lye or white phosphorus, which should be brushed off the patient. Antimicrobial ointments, sterile dressings, and tetanus prophylaxis are measures instituted later in the course of treatment, depending on the characteristics of the chemical agent and the size and location of the burn.

Which category of triage encompasses clients with serious health problems that are not immediately life threatening?

Urgent Explanation: Urgent clients have serious health problems that not immediately life threatening. They must be seen within 1 hour. Emergent clients have the highest priority with life-threatening conditions and they must be seen immediately. Nonurgent clients have episodic illness that can be addressed within 24 hours without increased morbidity. Fast-track clients require simple first aid or basic primary care and may be treated in the ED or safely referred to a clinic or physician's office.
