Brushing off all traces of the chemical from the patient's skin

A client undergoes a total abdominal hysterectomy. When assessing the client 10 hours later, the nurse identifies which finding as an early sign of shock?

Confusion

A patient has undergone a diagnostic peritoneal lavage. The nurse interprets which result as indicating a positive test?

Evidence of feces

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.

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

Lactated Ringer solution

Which guideline is appropriate for a nurse to implement while helping family members cope with the sudden death of a loved one? a. Show acceptance of the body by touching it, giving the family permission to touch. b. Inform the family that the client has passed on. c. Provide details of the factors attendant to the sudden death. d. Obtain orders for sedation for family members.

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).

Which of the following would the nurse identify as indicating that a client is experiencing a complete airway obstruction? Select all that apply.

Stridor Cyanosis Clutching of the neck Inability to speak

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

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

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.

A client has a gaping wound on his forearm that is bleeding profusely. Applying pressure to which pressure point would be most helpful? a. Subclavian b. Femoral c. Radial d. Brachial

Brachial Explanation: The pressure point at the brachial artery would be most appropriate because this site is proximal to the bleeding site. The femoral pressure point would be useful for bleeding in the lower extremities. The radial pressure point would be appropriate for bleeding in the wrist and hands. The subclavian pressure point would be used for bleeding in the upper anterior chest area.

When assessing a client with suspected carbon monoxide poisoning, which finding would be least reliable?

Cherry red skin color

The nurse is providing care to a client who will be ambulating for the first time after being extubated. The client tells the nurse, "I don't want to do this today. It's too soon and I am afraid I am not strong enough." What intervention should the nurse implement first for the client's fear of falling? a. Clear the area around the bed b. Evaluate the client for cognitive impairment c. Explore possible causes of the client's fear d. Allow the client to remain on bedrest

Explore possible causes of the client's fear Explanation: The client is exhibiting a fear of falling. For a client who has not mobilized in days due to mechanical ventilation and other medication interventions in the intensive care unit (ICU), ICU-acquired weakness is a reality. The client's concerns should be addressed by exploring the possible reasons for the fear of falling first. The client may be experiencing pain, dizziness or self-doubt. By identifying this cause, the nurse will be able to formulate the next action. The risk for falls is not due to cognitive impairment. This is evident in that the client is aware of current limitations and as a result is fearful. Preventative and rehabilitative measures to counter ICU-acquired weakness generally include early identification and treatment of potential causes of multiple organ failure (in particular severe sepsis and septic shock), avoiding unnecessary deep sedation and hyperglycemia, promotion of early mobilization, and thoughtful decisions regarding the risks versus benefits of corticosteroids. For these reasons, the client should not be encouraged to continue to have bedrest. Although the nurse should ensure the area around the bed is free of clutter to prevent a fall, this does not address the client's anxiety related to the fear of falling.

A patient is brought to the emergency department. Assessment reveals that the patient is lethargic and diaphoretic and complaining of right upper quandrant pain. Acetaminophen toxicity is suspected and an acetaminophen level is drawn. Which result would the nurse interpret as indicating toxicity for the patient if he weighs 70 kg?

10,500 mg Explanation: An acetaminophen level greater than or equal to 140 mg/kg would be considered toxic. For a patient weighing 70 kg, the toxic level would be 9800 mg. A level of 10,500 mg would be greater, thus indicating toxicity.

Permanent brain injury or death will occur within which time frame secondary to hypoxia?

3 to 5 minutes

A client is brought to the emergency department by ambulance. The client is seriously ill and unconscious. No family or friends are present. Which of the following would be most appropriate to do?

Document the client's condition and absence of friends or family for obtaining consent to treatment.

A patient arrives at the emergency department after taking more than 20 lorazepam tablets. Which of the following would the nurse anticipate that the patient would be given to reverse the effects of the drug?

Flumazenil

A nurse is working as a camp nurse during the summer. A camp counselor comes to the clinic after receiving a snakebite on the arm. What is the first action by the nurse?

Have the patient lie down and place the arm below the level of the heart.

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

An 85-year-old client is admitted to the ED. Heat stroke is suspected. The client's core temperature is 106.2°F (41.2°C), blood pressure (BP) 90/60 mm Hg, and pulse 102 bpm. The nurse understands that the primary treatment measure for the client will include

immersion of the client in a cold-water bath.

A client presents to the ED with a stab wound to the abdomen following an assault. It is suspected that the client has an injury to the pancreas. Which laboratory study is used to detect pancreatic injury?

Serum amylase Explanation: Serum amylase is analyzed to detect increasing levels, which suggests pancreatic injury or perforation of the gastrointestinal tract. A white blood cell count is done to detect an elevation. Urinalysis is done to detect hematuria. A hemoglobin and hematocrit test is done to evaluate trends reflecting the presence or absence of bleeding.

A client is brought to the emergency department with severe hemorrhage requiring masssive blood replacement. The nurse warms the blood in a commercial warmer based on the understanding that infusion of large amounts of blood could result in which of the following?

Cardiac arrest

The health care team in an intensive care unit have experienced a critical incident in which a young client died unexpectedly and the client's father physically attacked the senior physician treating the client. The client's father was arrested and escorted from the intensive care unit by police, against his will and in handcuffs. A critical incident stress management (CISM) staff meeting held 3 days after the incident took place. What would be the purpose for that meeting?

Debriefing

Which triage category refers to life-threatening or potentially life-threatening injury or illness requiring immediate treatment? a. Immediate b. Non acute c.Emergent d. Urgent

Emergent

The nurse in the ED is triaging patients during the shift. What does the nurse know is the first priority in treating any patient in the ED?

Establishing an airway.

The nurse is providing care to a client who will be ambulating for the first time after being extubated. The client tells the nurse, "I don't want to do this today. It's too soon and I am afraid I am not strong enough." What intervention should the nurse implement first for the client's fear of falling?

Explore possible causes of the client's fear

What is a common source of airway obstruction in an unconscious client? a. A foreign object b. The tongue c. edema d. Saliva or mucus

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 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? a. Tissue tearing away from supporting structures b. Incision of the skin with well-defined edges, usually long rather than deep c. Denuded skin d. Skin tear with irregular edges and vein bridging

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.

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 has come on shift to find that a client newly admitted to the ICU is confused and persistently trying to get out of bed despite being comforted and re-oriented by the nurse. The client begins to pull on the peripheral intravenous line in the hand and speaking in non-sensical terms. The client's history indicates a sudden onset of neurological symptoms after developing a bacterial infection. The nurse anticipates providing care for which health problem? a.Fever b. Delirium c. Pain d. Anxiety

Delirium Explanation: Delirium is a confused state that has a sudden onset and can last hours to days or weeks; it is characterized by hyperactivity and has the potential to be reversible. The client who quickly becomes confused and agitated while attempting to pull out IV lines and get out of bed is experiencing delirium. The nurse caring for this client should anticipate the need to provide close monitoring to prevent injury. Although clients can experience a high level of stress with both pain and anxiety, which often accompany one another, these problems do not cause confusion and disorientation. Nursing interventions would be aimed at reducing pain and anxiety with the use of medications and other non-pharmacological interventions that enhance client comfort. Although fever can accompany delirium, it does not produce confusion and disorientation on its own.

The nurse is caring for a client with diabetes who requires a peripheral intravenous (PIV) line for antibiotic administration and to treat dehydration. The nurse must avoid inserting which type of PIV?

Foot Explanation: PIV lines should rarely be used in the foot for various reasons. They limit the client's ability to ambulate and tend to occlude easily. These types of IVs should never be used in clients with diabetes due to the risk that the client has neuropathy and cannot feel injury caused by the IV catheter. IV lines in the forearm and hands are acceptable and are commonly used sites. These sites would be safe to use for a client with diabetes. The upper arm is a site of choice for the insertion of a peripherally inserted central line (PICC) not a PIV line. Although, this site would not be an option for a PIV line, it would be safe for use in a client with diabetes if warranted.

The nurse has received a client into care who was admitted with a heroin overdose. The client has a 5-year history of illicit substance use with cocaine, heroine and oxycodone. The client develops a sudden onset of wheezing, restlessness and a cough that produces a frothy, pink sputum. The nurse suspects the client has most likely developed which complication of opioid overdose?

Pulmonary edema Explanation: The nurse should suspect the client has developed pulmonary edema, which is frequently seen in clients who abuse/overdose on narcotics. Many drugs — ranging from illegal drugs such as heroin and cocaine to aspirin — are known to cause noncardiogenic pulmonary edema. Pneumonia is not the likely cause given the sudden onset of respiratory symptoms accompanied but coughing up the pink frothy sputum. The client's history of illicit substance use and now overdose on these drugs should lead the nurse to suspect pulmonary edema is the cause of the sudden onset of these symptoms over congestive heart failure, in which clients have a more gradual onset of respiratory issues. Although a panic attack can manifest in shortness or breath and restlessness, the client would not be wheezing or producing blood tinged sputum with a cough. Panic attacks do, however, have a sudden onset and can cause the client chest pain and a sense of doom.

A nurse is caring for a client who is experiencing alcohol withdrawal. Which statement best indicates that the client understands the need for long-term treatment? a. The client agrees to attend supportive counseling b. The client agrees to ongoing participation in one or more support groups. c. The client agrees to detoxification, rehabilitation, and participation in an aftercare program. d. The client agrees to involve his family in psychotherapy.

The client agrees to detoxification, rehabilitation, and participation in an aftercare program. Explanation: Detoxification, rehabilitation, and participation in an aftercare program are the only options that address the client's long-term treatment needs. Supportive counseling, family involvement, and support-group participation are important aspects of the treatment process, but they don't address the client's need for long-term treatment.

The intensive care unit nurse is assessing a client who is going to require a peripheral intravenous (PIV) line for fluids. The nurse should consider what information in the client's health history when deciding the site for the PIV?

The client has had a mastectomy on the right side Explanation: Contraindications to the placement of a PIV line in any specific placement (right vs. left side) will include history of mastectomy, arterial-venous shunt placement, peripherally inserted central catheter (PICC) line placement, thrombus, trauma, and other device placements, such as splints and casts. The nurse will only have the option to start the PIV on a site in the client's left arm if the client has had a ride-sided mastectomy. A history of hypertension does not preclude the client from having a PIV inserted in any specific location. Although fluid requirements are monitored more strictly with clients who are on a fluid volume restriction, this does not influence the placement of the PIV. The nurse should always be aware of the risks of a PIV for a client with a falls history. The tubing can be a tripping hazard, therefore, the client with a falls history who requires a PIV should be closely monitored but this does not preclude the client from having a PIV inserted.

The nurse has commenced a transfusion of fresh frozen plasma (FFP) and notes the client is exhibiting symptoms of a transfusion reaction. After the nurse stops the transfusion, what is the next required action?

Run a normal saline line to keep the vein open

The nurse in the hospital emergency department is assessing a patient who fell while intoxicated with alcohol. The nurse is using the Clinical Institute Withdrawal Assessment-Alcohol (CIWA-A) scale to assess the patient's need for a benzodiazipine medication. In order to assess for auditory disturbances, which question should the nurse ask the patient?

"Are you hearing anything that is disturbing you?"

The nurse is administering 100% oxygen to a patient with carbon monoxide poisoning and obtains a carboxyhemoglobin level. Which level would the nurse interpret as indicating that oxygen therapy can be discontinued?

4% Explanation: Oxygen is administered until the carboxyhemoglobin level is less than 5%

A triage nurse in the ED determines that a patient with dyspnea and dehydration is not in a life-threatening situation. What triage category will the nurse choose?

Urgent

A patient with frostbite to both lower extremities from exposure to the elements is preparing to have rewarming of the extremities. What intervention should the nurse provide prior to the procedure? a. Administer an analgesic as ordered. b. Elevate the legs. c. Massage the extremities. d. Apply a heat lamp.

Administer an analgesic as ordered. Explanation: During rewarming, an analgesic for pain is administered as prescribed, because the rewarming process may be very painful. To avoid further mechanical injury, the body part is not handled. Massage is contraindicated.

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.

The nurse is providing care for a client who is experiencing alcohol withdrawal. The client reports, "I cannot fall or stay asleep."

Ask the family if they would like to view the body. Provide a private place for the family to be together. Allow the family to express their emotions freely.

The nurse is admitting a patient with a penetrating abdominal injury from a knife wound. What should the nursing measures for a penetrating abdominal injury include? (Select all that apply.)

Assessing for manifestations of hemorrhage Covering any protruding viscera with sterile dressings soaked in normal saline solution Looking for any associated chest injuries

The nurse is caring for a client who is agitated and confused. The client is persistently trying to get out of bed and attempted to remove the peripheral IV. The nurse has attempted to re-orient the client; however, this was not effective in de-escalating the client's agitation. The client yells, "I am going to punch you in the face!" What is the nurse's next action?

Call security personnel to assist

Clients with Medicaid use the emergency department more often than clients with private health insurance.

A client presents to the ED following a motor vehicle collision. The client is suspected of having internal hemorrhage. The nurse assesses the client for signs and symptoms of shock. Which are signs and symptoms of shock? Select all that apply.

Cool, moist skin Decreasing blood pressure Delayed capillary refill Increasing heart rate

The nurse has come on shift to find that a client newly admitted to the ICU is confused and persistently trying to get out of bed despite being comforted and re-oriented by the nurse. The client begins to pull on the peripheral intravenous line in the hand and speaking in non-sensical terms. The client's history indicates a sudden onset of neurological symptoms after developing a bacterial infection. The nurse anticipates providing care for which health problem?

Delirium

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? a. Diving in an ocean b. Running a race in hot humid weather c. Working in a chemical plant d. Swimming in a lake

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 caring for a patient with multiple injuries and performs the following. Place these actions in the order in which the nurse would perform them. Use all options.

Establish airway and ventilation Control hemorrhage Prevent and treat shock Assess for head and neck injuries Assess for abdomen, back, and extremity injuries Splint fractures

For a patient who is experiencing multiple injuries, which sequence of medical or nursing management would the nurse identify as a priority?

Establish an airway, control hemorrhage, prevent hypovolemic shock, assess for head injuries.

Nursing students are reviewing the categories of intra-abdominal injuries. The students demonstrate understanding of the information when they identify which of the following as examples of penetrating trauma? Select all that apply. a. Being struck with a baseball bat b. Motor-vehicle crash c. Gunshot wound d. Knife-stab wound e. Fall from a roof

Gunshot wound Knife-stab wound Explanation: Examples of penetrating trauma include gunshot wounds and stab wounds. Motor vehicle crashes, falls, and being struck with a baseball bat are examples of blunt trauma.

The nurse educator is providing orientation to a group of nurses newly hired to an intensive care unit. The group of nurses are correct in stating which is the most common type of shock managed in critical care?

Hypovolemic

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? a. Gastric lavage b. Induced vomiting c. Dilution with water or milk d. Administration of activated charcoal

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.

The nurse is caring for a client suffering from carbon monoxide poisoning. The nurse will expect the client to 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.

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. Jaw-thrust b. Abdominal thrust c. Seldinger d. Head tilt-chin lift

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 care to an older adult client who has frostbite of the feet. Which action would be least appropriate? a. Massaging the feet b. Placing sterile cotton between the toes after rewarming c. Restricting ambulation d. Providing an analgesic for pain

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.

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? a. Measure the circumference of the arm. b.Administer diphenhydramine (Benadryl). c. Assess peripheral pulses. d. Administer cimetidine (Tagamet).

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.

Which medication reverses severe respiratory depression and coma? a. Flumazenil b. N-acetylcysteine c. Diazepam d. Naloxone hydrochloride

Naloxone hydrochloride Explanation: Naloxone hydrochloride, a narcotic antagonist, reverses respiratory depression and coma. Diazepam is a benzodiazepine. Flumazenilis a benzodiazepine antagonist. N-acetylcysteine is used for acetaminophen toxicity.

A client presents to the ED following a chemical burn. The client identifies the source of the burn as white phosphorus. The nurse knows that treatment will include

No application of water to the burn.

The nurse is providing care for a client who was admitted to the intensive care unit after suffering cardiovascular collapse secondary to a methamphetamine overdose. The client is semi-conscious and has a nasopharyngeal in place. The nurse anticipates this client may require which interventions? Select all that apply.

Provide airway support and ventilation Minimize lights and noise disturbances Administer antipsychotic medication Follow the unit seizure protocol

The nurse is preparing to transfer a client from the ICU to a medical unit in the hospital. To ensure consistent communication regarding the client's care needs to the receiving unit, in what sequence of steps should the nurse organize the report?

Obtain the client's health record State the client's admission date and current diagnosis Provide a brief statement of current concerns Give the client's pertinent medical history Provide the most recent vital signs and assessment findings Give recommendations for what needs to be done for the client

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? a. Over-the-bed heaters b. Warmed humidified oxygen by ventilator c. Forced warm air blankets d. Cardiopulmonary bypass

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.

When preparing to perform abdominal thrusts on a client with an airway obstruction, which of the following would be most appropriate? a. Having the conscious client lie down b. Using a sequence of four thrusts, each progressing in intensity c. Placing the thumb side of one hand at the xiphoid process d. Positioning the hands in the midline slightly above the umbilicus

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.

A nurse is providing care to a client in the emergency department and walks into the hallway to get equipment. All of a sudden, gunshots are heard. Which of the following would be the nurse's priority?

Protecting himself or herself

The nurse in an intensive care unit is caring for a client who requires blood work to assess for changes in blood coagulation due to heparin therapy. Which test should the nurse expect to see prescribed for this value to be assessed? a. Arterial blood gas (ABG) b. Prothrombin time (PTT) c. White blood cell (WBC) d. Lactate

Prothrombin time (PTT) Explanation: Prothrombin time (PTT) is assessed in the blood work to identify coagulopathy or presence of chemically induced anticoagulation. This client is receiving heparin, an intravenous medication that helps to prevent the formation of clots; therefore, the PTT must be monitored regularly to ensure the medication remains within the therapeutic range. The client's white blood cell (WBC) reflects a count of this blood component to detect elevation of these cells, which is related to increased physiological stress. Typically this stress is infection, but it can also increase when there is trauma. Lactate would be drawn with the blood work to determine acidosis and need for continued resuscitation. Arterial blood gas (ABG) is evaluated to determine pH for the presence of acidosis, the base deficit for resuscitation evaluation, and ventilation parameters (PaCO2, PaO2).

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.

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 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.

The nurse is caring for a client in the intensive care unit who is recovering from trauma as a result of a motor vehicle accident that claimed the life of the client's friend. While the nurse is performing a dressing change on the client's surgical wound, the client states, "I don't deserve to live. I have just been thinking about ending it all." As the nurse assesses the client's imminent risk for suicide, what contributing factors need to be considered? Select all that apply.

The client attempted suicide as a teenager. The client's maternal uncle committed suicide. The client had a close relationship to the accident victim.

When providing care to a client who has experienced multiple trauma, which of the following would be most important for the nurse to keep in mind?

The client is assumed to have a spinal cord injury until proven otherwise.

The nurse is caring for a patient in the ED who is breathing but unconscious. In order to avoid an upper airway obstruction, the nurse is inserting an oropharyngeal airway. How would the nurse insert the airway?

Upside down and then rotated 180 degrees Explanation: The nurse should insert the oropharyngeal airway with the tip facing up toward the roof of the mouth until it passes the uvula and then rotate the tip 180 degrees so that the tip is pointed down toward the pharynx. This displaces the tongue anteriorly, and the patient then breathes through and around the airway.

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

Medications Latex Insect stings Shellfish

Acetaminophen overdose is treated with administration of which medication? a. Diazepam b. Naloxone c. Flumazenil d. N-acetylcysteine

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.

Following a motor vehicle collision, a client is brought to the ED for evaluation and treatment. The client is being assessed for intra-abdominal injuries. The client reports severe left shoulder pain (pain score of 10 on a 1 to 10 scale). The nurse suspects injury to the

spleen

• Patient with laryngeal edema secondary to anaphylaxis • Patient with an obstructed larynx • Patient with extensive facial trauma Cricothyroidotomy is used in emergencies when endotracheal intubation is either not possible or contraindicated. Examples include airway obstruction from extensive maxillofacial trauma, cervical spine injury, laryngospasm, laryngeal edema after an allergic reaction or extubation, hemorrhage into neck tissue, and obstruction of the larynx.

The nurse is caring for an intensive care unit client who has died with family members at the bedside. The death was sudden and unexpected resulting from a car accident that took place three days ago. The family is upset and the client's partner, crying loudly, yells, "How did this happen? We were just about to celebrate his birthday. He can't be gone!" The family member continues to cry inconsolably. How should the nurse respond? a." I will get you some medication that will help you feel more calm." b."It is important to face the reality that he is gone." c. "He has passed on to a better place now." d. "We did everything we could possibly do to try to save his life."

"We did everything we could possibly do to try to save his life." Explanation: In order to help the family cope with the sudden death of their loved one, it is helpful for the nurse to explain that the care team employed all medical interventions possible to try to save the client's life. With the support of other members of the health care team, the nurse can take the time to explain what life saving treatments were rendered. The nurse should avoid giving sedation to family members; this may mask or delay the grieving process, which is necessary to achieve emotional equilibrium and to prevent prolonged depression. It is important that the nurse avoid using euphemisms such as "passed on." Instead the nurse should show the family that he or she cares by touching, and offering coffee, water, and the services of a chaplain. The nurse should encourage the family to express emotion including events leading up to the event that led to the client's death. The nurse should not challenge initial feelings of anger or denial.

The ED staff work collaboratively and follow the ABCDE method to establish and treat health priorities effectively in a client experiencing a trauma. Which action is completed by the nurse when implementing the "D" element of this method? a. Providing cervical spine protection b. Assessing the client's Glasgow Coma Scale score c. Managing hypothermia d. Undressing the client quickly

Assessing the client's Glasgow Coma Scale score Explanation: The primary survey focuses on stabilizing life-threatening conditions. The ED staff work collaboratively and follow the ABCDE (airway, breathing, circulation, disability, exposure) method. While implementing the D element, the nurse determines neurologic disability by assessing neurologic function using the Glasgow Coma Scale and performing a motor and sensory evaluation of the spine. A quick neurologic assessment may be performed using the AVPU mnemonic: A, alert: is the client alert and responsive? V, verbal: does the client respond to verbal stimuli? P, pain: does the client respond only to painful stimuli? U, unresponsive: is the client unresponsive to all stimuli, including pain? The other interventions are not included in this element of the primary survey.

A nurse is assessing a patient who is suspected of having a partial airway obstruction. Which of the following would the nurse expect to find? a. Severe respiratory distress b. High-pitched noises on inhalation c. Spontaneous coughing d. Cyanosis

Spontaneous coughing Explanation: If a patient can breathe and cough spontaneously, a partial airway obstruction should be suspected. If the patient demonstrates a weak, ineffective cough, high-pitched noise while inhaling, increased respiratory difficulty, or cyanosis, the patient should be managed as if there were a complete airway obstruction.

A patient is brought to the emergency department after being locked outside of her house in the frigid weather for several hours. The nurse suspects that the patient has sustained frostbite of her hand based on which of the following findings?

Hand that is insensitive to touch

A client arrives at the emergency department and is experiencing a severe allergic reaction to a bee sting. The client received treatment and is being discharged. Which client statement indicates that additional teaching about exposure prevention is needed? a. "I should always wear something on my feet when I'm outside." b. "If a bee comes near me, I should stay still." c. "Brightly colored clothes help to ward off bees." d. "I need to avoid using perfumes and scented soaps when I'm going outside."

"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 victim of a sexual assault. The client is fearful and experiencing flashbacks. The nurse recognizes that the client is experiencing which phase of the psychological reaction to rape? a. Reorganization phase b. Denial phase c. Heightened anxiety phase d.Acute disorganization phase

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.

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.

A client is admitted to the ED after a near-drowning accident. The client is diagnosed with saltwater aspiration. The nurse will observe the client for several hours to monitor for symptoms of

pulmonary edema. Explanation: Resultant pathophysiologic changes and pulmonary injury depend on the type of fluid (fresh or salt water) and the volume aspirated. Freshwater aspiration results in a loss of surfactant and therefore an inability to expand the lungs. Saltwater aspiration leads to pulmonary edema from the osmotic effects of the salt within the lungs. If a person survives submersion, acute respiratory distress syndrome, resulting in hypoxia, hypercarbia, and respiratory or metabolic acidosis, can occur. The client would experience hypernatremia. Hypothermia and head injury may be associated with near drowning but would be apparent at the time of admission and would not develop after several hours.

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? a. Administer analgesic medications as ordered. b. Rupture any hemorrhagic blebs that are noted. c. Keep the hand in the circulating bath for 1 hour. d. Have the client complete active range-of-motion exercises.

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.
