Lewis: MED-SURG: Chapter 69: Emergency, Terrorism, and Disaster Nursing

When planning the response to the potential use of smallpox as an agent of terrorism, the emergency department (ED) nurse-manager will plan to obtain sufficient quantities of a. blood. b. vaccine. c. atropine. d. antibiotics.

B Smallpox infection can be prevented or ameliorated by the administration of vaccine given rapidly after exposure. The other interventions would be helpful for other agents of terrorism but not for smallpox.

When a patient is admitted to the emergency department after a submersion injury, which assessment will the nurse obtain first? a. Apical pulse b. Lung sounds c. Body temperature d. Level of consciousness

B The priority assessment data are how well the patient is oxygenating, so lung sounds should be assessed first. The other data also will be collected rapidly but are not as essential as the lung sounds.

During the primary assessment of a trauma victim, the nurse determines that the patient is breathing and has an unobstructed airway. Which action should the nurse take next? a. Observe the patient's respiratory effort. b. Check the patient's level of consciousness. c. Palpate extremities for capillary refill time. d. Examine the patient for any external bleeding.

A Even with a patent airway, patients can have other problems that compromise ventilation, so the next action is to assess the patient's breathing. The other actions also are part of the initial survey but assessment of breathing should be done immediately after assessing for airway patency.

A patient who has experienced blunt abdominal trauma during a car accident is complaining of increasing abdominal pain. The nurse will plan to teach the patient about the purpose of a. ultrasonography. b. peritoneal lavage. c. nasogastric (NG) tube placement. d. magnetic resonance imaging (MRI).

A For patients who are at risk for intraabdominal bleeding, focused abdominal ultrasonography is the preferred method to assess for intraperitoneal bleeding. An MRI would not be used. Peritoneal lavage is an alternative, but it is more invasive. An NG tube would not be helpful in diagnosis of intraabdominal bleeding.

A patient arrives in the emergency department (ED) a few hours after taking "20 to 30" acetaminophen (Tylenol) tablets. Which action will the nurse plan to take? a. Give N-acetylcysteine (Mucomyst). b. Discuss the use of chelation therapy. c. Have the patient drink large amounts of water. d. Administer oxygen using a non-rebreather mask.

A N-acetylcysteine is the recommended treatment to prevent liver damage after acetaminophen overdose. The other actions might be used for other types of poisoning, but they will not be appropriate for a patient with acetaminophen poisoning.

When preparing to rewarm a patient with hypothermia, the nurse will plan to a. attach a cardiac monitor. b. insert a urinary catheter. c. assist with endotracheal intubation. d. have sympathomimetic drugs available.

A Rewarming can produce dysrhythmias, so the patient should be monitored and treated if necessary. Urinary catheterization and endotracheal intubation are not needed for rewarming. Sympathomimetic drugs tend to stimulate the heart and increase the risk for fatal dysrhythmias such as ventricular fibrillation.

A patient arrives in the emergency department after exposure to radioactive dust. Which action should the nurse take first? a. Place the patient in a shower. b. Obtain the patient's vital signs. c. Determine the type of radioactive agent. d. Obtain a baseline complete blood count.

A The initial action should be to protect staff members and decrease the patient's exposure to the radioactive agent by decontamination. The other actions can be done after the decontamination is completed.

When assessing a patient admitted to the emergency department (ED) with a broken arm and facial bruises, the nurse notes multiple additional bruises in various stages of healing. Which statement or question by the nurse is most appropriate? a. "Is someone at home hurting you?" b. "You should not return to your home." c. "Would you like to see a social worker?" d. "I have to report this abuse to the police."

A The nurse's initial response should be to further assess the patient's situation. Telling the patient not to return home may be an option once further assessment is done. The patient, not the nurse, is responsible for reporting the abuse. A social worker may be appropriate once further assessment is completed.

A triage nurse in a busy emergency department assesses a patient who complains of 6/10 abdominal pain and states, "I had a temperature of 104.6º F (40.3º C) at home." The nurse's first action should be to a. assess the patient's current vital signs. b. obtain a clean-catch urine for urinalysis. c. tell the patient that it may be several hours before being seen by the doctor. d. ask the health care provider to order an analgesic medication for the patient.

A The patient's pain and statement about an elevated temperature indicate that the nurse should obtain vital signs before deciding how rapidly the patient should be seen by the health care provider. A urinalysis may be needed, but vital signs will provide the nurse with the data needed to determine this. The health care provider will not order a medication before assessing the patient.

The following actions are part of the routine emergency department (ED) protocol for a patient who has been admitted with multiple bee stings to the hands. Which action should the nurse take first? a. Remove the patient's rings. b. Place ice packs on both hands. c. Apply calamine lotion to any itching areas. d. Give diphenhydramine (Benadryl) 100 mg PO.

A The patient's rings should be removed first because it might not be possible to remove them if swelling develops. The other orders also should be implemented as rapidly as possible after the nurse has removed the jewelry.

Following an earthquake, patients are triaged by emergency medical personnel and are transported to the hospital. Which of these patients will the nurse need to assess first? a. A patient with a red tag b. A patient with a blue tag c. A patient with a yellow tag d. A patient with a green tag

A The red tag indicates a patient with a life-threatening injury requiring rapid treatment. The other tags indicate patients with less urgent injuries or those who are likely to die.

After resuscitation, a patient who had a cardiac arrest is nonresponsive to commands and therapeutic hypothermia is prescribed. Which action will the nurse include in the plan of care? a. Rapidly infuse cold normal saline. b. Avoid the use of sedative medications. c. Check neurologic status every 30 minutes. d. Rewarm if temperature is >91° F (32.8° C).

A When therapeutic hypothermia is used postresuscitation, cold normal saline is infused to rapidly lower body temperature to 89.6° F to 93.2° F (32° C to 34° C). Since hypothermia will decrease brain activity, neurologic assessment every 30 minutes is not needed. Sedative medications are administered during therapeutic hypothermia.

A patient who is unconscious after a fall from a ladder is transported to the emergency department by family members. During the primary survey of the patient, the nurse should a. assess the patient's vital signs. b. attach a cardiac electrocardiogram (ECG) monitor. c. obtain a Glasgow Coma Scale score. d. ask about chronic medical conditions.

C The Glasgow Coma Scale is included when assessing for disability during the primary survey. The other information is part of the secondary survey.

The nurse provides information to a patient who was exposed to anthrax by inhalation. The nurse determines the teaching has been successful if the patient makes which statement? A. "Anthrax can be spread by person-to-person contact." B. "It is not necessary to receive the anthrax vaccine." C. "An antibiotic will be prescribed for 2 months." D. "Antibiotics are only indicated for an active infection."

Answer: C. "An antibiotic will be prescribed for 2 months." Rationale: Postexposure prophylaxis includes a 60-day course of antibiotics. Ciprofloxacin (Cipro) is the treatment of choice. Anthrax is not spread by person-to-person contact; anthrax is spread by direct contact with the bacteria and its spores. The patient may receive the anthrax vaccine (three doses); if vaccinated, the course of antibiotic therapy is reduced to 30 days. Antibiotics are indicated after exposure to inhaled anthrax. Ch. 69

Which patient should the nurse prepare to transfer to a regional burn center? A. A 53-year-old patient with a chemical burn to the anterior chest and neck B. A 25-year-old pregnant patient with a carboxyhemoglobin level of 1.5% C. A 42-year-old patient who is scheduled for skin grafting of a burn wound D. A 39-year-old patient with a partial-thickness burn to the right upper arm

Answer: A. A 53-year-old patient with a chemical burn to the anterior chest and neck Rationale: The American Burn Association (ABA) has established referral criteria to determine which burn injuries should be treated in burn centers where specialized facilities and personnel are available to handle this type of trauma (see Table 25-3). Patients with chemical burns should be referred to a burn center. A normal serum carboxyhemoglobin level for nonsmokers is 0% to 1.5% and for smokers is 4% to 9%. Skin grafting for burn wound management is not a criteria for a referral to a burn center. Partial-thickness burns greater than 10% total body surface area (TBSA) should be referred to a burn center; a burn to the right upper arm is 4% TBSA. Ch. 25

The nurse is caring for a 71 kg patient during the first 12 hours after a thermal burn injury. Which outcomes if observed by the nurse would indicate adequate fluid resuscitation (select all that apply)? A. Heart rate is 94 beats/minute. B. Mean arterial pressure is 54 mm Hg. C. Urine output is 46 mL/hour. D. Urine specific gravity is 1.040. E. Systolic blood pressure 88 mm Hg

Answer: A. Heart rate is 94 beats/minute. C. Urine output is 46 mL/hour. Rationale: Assessment of the adequacy of fluid resuscitation is best made using either urine output or cardiac factors. Urine output should be 0.5 to 1 mL/kg/hr (or 75 to 100 mL/hr for an electrical burn patient with evidence of hemoglobinuria/myoglobinuria). Cardiac factors include a mean arterial pressure (MAP) greater than 65 mm Hg, systolic blood pressure (BP) greater than 90 mm Hg, heart rate less than 120 beats/minute. Normal range for urine specific gravity is 1.003 to 1.030. Ch. 25

A nurse manager educates the emergency department staff about their roles during a disaster with mass casualties. Which primary responsibility should the nurse manager discuss with the staff? A. Learn the hospital emergency response plan. B. Report acts of violence to security personnel. C. Contact the American Red Cross for assistance. D. Notify local, state, and national authorities.

Answer: A. Learn the hospital emergency response plan. Rationale: All health care providers need to be prepared for a mass casualty incident; the priority responsibility is to know the agency's emergency response plan. Ch. 69

The nurse is planning to change the dressing covering a deep partial-thickness burn of the right lower leg. Which prescribed medication should the nurse administer 30 minutes before the scheduled dressing change? A. zolpidem (Ambien) B. morphine sulfate C. sertraline (Zoloft) D. enoxaparin (Lovenox)

Answer: B. morphine sulfate Rationale: Deep partial-thickness burns result in severe pain related to nerve injury. The nurse should plan to administer analgesics before the dressing change to promote patient comfort. Morphine sulfate is a common opioid used for pain control. Sedative/hypnotics and antidepressant agents can also be given with analgesics to control the anxiety, insomnia, and/or depression that patients may experience. Zolpidem promotes sleep; sertraline is an antidepressant; and enoxaparin is an anticoagulant. Ch. 25

The nurse is providing emergent care for a patient with a possible inhalation injury sustained in a house fire. The patient is anxious and disoriented, and the skin is a cherry red color. Which action should the nurse take first? A. Assist the patient to a high Fowler's position. B. Teach the patient deep breathing exercises. C. Allow the patient to verbalize feelings. D. Administer 100% humidified oxygen.

Answer: D. Administer 100% humidified oxygen. Rationale: Carbon monoxide (CO) poisoning may occur in house fires; CO displaces oxygen on the hemoglobin molecule resulting in hypoxia. High levels of CO in the blood result in a skin color that is described as cherry red. Hypoxia may cause anxious behaviors and altered mental status. Emergency treatment for inhalation injury and CO poisoning includes the immediate administration of 100% humidified oxygen. The other interventions are appropriate for inhalation injury but are not as emergent as oxygen administration. Ch. 25

The nurse is caring for a patient who sustained a deep partial thickness burn to the anterior chest area. Which statement would be appropriate for the nurse to include when documenting the appearance of this type of burn? ]A. Skin is hard with a dry, waxy white appearance with visible venous patterns. B. Skin blanches with pressure and is red with delayed blister formation. C. Skin is red and shiny with the presence of clear fluid-filled blisters. D. Skin is charred and leathery with visible muscles, tendons, and bones

Answer: C. Skin is red and shiny with the presence of clear fluid-filled blisters. Rationale: Deep partial thickness burns have fluid-filled vesicles that are red and shiny; may appear wet (if vesicles have ruptured); and mild to moderate edema may be present. Deep partial thickness burns result in severe pain related to nerve injury. Superficial partial thickness burns are red and blanch with pressure; pain and mild edema are present. Superficial partial thickness burns may have vesicles that appear 24 hours after the burn injury. Full-thickness burns are dry, waxy white, leathery, or hard; thrombosed vessels may be visible. Full-thickness burns result in an insensitivity to pain because of nerve destruction, and there may be involvement of muscles, tendons, and bones. Ch. 25

A patient arrives in the emergency department after ingesting 8 g of acetaminophen (Tylenol). Which question is most important for the nurse to ask? A. Have you tried to commit suicide before? B. Do you feel like you have a fever? C. What time did you take the Tylenol? D. Are you experiencing any abdominal pain?

Answer: C. What time did you take the Tylenol? Rationale: Acetaminophen will bind to activated charcoal and pass through the gastrointestinal tract without being absorbed. Activated charcoal is most effective if administered within 1 hour of ingestion of acetaminophen and other select poisons. Ch. 69

A patient is admitted to the emergency department with cold exposure and a core body temperature of 86.6o F (30.3o C). Which action is most appropriate for the nurse to take? A. Immerse the extremities in a water bath (102° to 108° F) [38.9° to 42.2° C]) B. Place an air-filled warming blanket on the patient. C. Position patient under a radiant heat lamp. D. Administer warmed intravenous (IV) fluids.

Answer: D. Administer warmed intravenous (IV) fluids. Rationale: A patient with a core body temperature of 86.6o F (30.3o C) has moderate hypothermia. Active core rewarming is used for moderate to severe hypothermia and includes administration of warmed IV fluids (109.4° F [43° C]). Patients with moderate to severe hypothermia should have the core warmed before the extremities to prevent after drop (or further drop in core temperature). This occurs when cold peripheral blood returns to the central circulation. Use passive or active external rewarming for mild hypothermia. Active external rewarming involves fluid-filled warming blankets or radiant heat lamps. Immersion of extremities in a water bath is indicated for frostbite. Ch. 69

A nurse is performing triage in the emergency department. Which patient should the nurse see first? A. 18-year-old patient with type 1 diabetes mellitus who has a 4-cm laceration on right leg. B. 32-year-old patient with drug overdose who is unresponsive with poor respiratory effort. C. 56-year-old patient with substernal chest pain who is diaphoretic with shortness of breath. D. 78-year-old patient with right hip fracture who is confused; blood pressure is 98/62 mm Hg.

Answer: B. 32-year-old patient with drug overdose who is unresponsive with poor respiratory effort. Rationale: Patient with drug overdose is unstable and needs to be seen immediately. Patient with chest pain (possible myocardial infarction) should be seen second. Patient with hip fracture should be seen third. Patient with laceration is the most stable and should be seen last. Ch. 69

A patient's family members are in the patient room when the patient has a cardiac arrest and emergency personnel start resuscitation measures. Which action is best for the nurse to take initially? a. Have the family wait outside the patient room with a designated staff member to provide emotional support. b. Keep the family in the room and assign a member of the team to explain the care given and answer questions. c. Ask the family members about whether they would prefer to remain in the patient room or wait outside the room. d. Advise the family members that patients are comforted by having family members present during resuscitation efforts.

C Although many family members and patients report benefits from family presence during resuscitation efforts, the nurse's initial action should be to determine the preference of these family members. The other actions may be appropriate, but this will depend on what is learned when assessing family preferences.

A patient with hypotension and temperature elevation after doing yard work on a hot day is treated in the ED. After the nurse has completed discharge teaching, which statement by the patient indicates that the teaching has been effective? a. "I will take salt tablets when I work outdoors in the summer." b. "I should take acetaminophen (Tylenol) if I start to feel too warm." c. "I should have sports drinks when exercising outside in hot weather." d. "I will get into a cool environment if I notice that I am feeling confused."

C Electrolyte solutions such as sports drinks help replace fluid and electrolytes lost when exercising in hot weather. Salt tablets are not recommended because of the risks of gastric irritation and hypernatremia. Antipyretic medications are not effective in lowering body temperature elevations caused by excessive exposure to heat. A patient who is confused is likely to have more severe hyperthermia and will be unable to remember to take appropriate action.

The emergency department (ED) triage nurse is assessing four victims of an automobile accident. Which patient has the highest priority for treatment? a. A patient with absent pedal pulses b. A patient with an open femur fracture c. A patient with a sucking chest wound d. A patient with bleeding of facial lacerations

C Most immediate deaths from trauma occur because of problems with ventilation, so the patient with a sucking chest wound should be treated first. Face and head fractures can obstruct the airway, but the patient with facial injuries has lacerations only. The other two patients also need rapid intervention but do not have airway or breathing problems.

A patient who experienced a near drowning accident in a local lake, but now is awake and breathing spontaneously, is admitted for observation. Which action will be most important for the nurse to take during the observation period? a. Listen to heart sounds. b. Palpate peripheral pulses. c. Auscultate breath sounds. d. Check pupil reaction to light.

C Since pulmonary edema is a common complication after near drowning, the nurse should assess the breath sounds frequently. The other information also will be collected by the nurse, but it is not as pertinent to the patient's admission diagnosis.

An unresponsive 78-year-old is admitted to the emergency department (ED) during a summer heat wave. The patient's core temperature is 106.2° F (41.2° C), blood pressure (BP) 86/52, and pulse 102. The nurse initially will plan to a. administer an aspirin rectal suppository. b. start O2 at 6 L/min with a nasal cannula. c. apply wet sheets and a fan to the patient. d. infuse lactated Ringer's solution at 1000 mL/hr.

C The priority intervention is to cool the patient. Antipyretics are not effective in decreasing temperature in heat stroke, and 100% oxygen should be given, which requires a high flow rate through a non-rebreather mask. An older patient would be at risk for developing complications such as pulmonary edema if given fluids at 1000 mL/hr.

These four patients arrive in the emergency department after a motor vehicle crash. In which order should they be assessed? Put a comma and space between each answer choice (a, b, c, d, etc.) ____________________ a. A 72-year-old with palpitations and chest pain b. A 45-year-old complaining of 6/10 abdominal pain c. A 22-year-old with multiple fractures of the face and jaw d. A 30-year-old with a misaligned right leg with intact pulses

C, A, B, D The highest priority is to assess the 22-year-old patient for airway obstruction, which is the most life-threatening injury. The 72-year-old patient may have chest pain from cardiac ischemia and should be assessed and have diagnostic testing for this pain. The 45- year-old patient may have abdominal trauma or bleeding and should be seen next to assess circulatory status. The 30-year-old appears to have a possible fracture of the right leg and should be seen soon, but this patient has the least life-threatening injury.

When rewarming a patient who arrived in the emergency department (ED) with a temperature of 87° F, which assessment indicates that the nurse should discontinue the rewarming? a. The patient stops shivering. b. The BP decreases to 85/40 mm Hg. c. The patient develops atrial fibrillation. d. The core temperature is 94° F (34.4° C).

D A core temperature of 89.6° F to 93.2° F (32° C to 34° C) indicates that sufficient rewarming has occurred. Dysrhythmias, hypotension, and shivering may occur during rewarming and should be treated but are not an indication to stop rewarming the patient.

An 18-year-old is brought to the emergency department (ED) with multiple lacerations and tissue avulsion of the right hand. When asked about tetanus immunization, the patient denies having any previous vaccinations. The nurse will anticipate administration of a. tetanus-diphtheria toxoid (Td) only. b. tetanus immunoglobulin (TIG) only. c. TIG and tetanus-diphtheria toxoid (Td). d. TIG and tetanus-diphtheria toxoid and pertussis vaccine (Tdap).

D For an adult with no previous tetanus immunizations, TIG and Tdap are recommended. The other immunizations are not sufficient for this patient.

Gastric lavage and administration of activated charcoal are prescribed for an unconscious patient who has been admitted to the emergency department (ED) after ingesting 30 diazepam (Valium) tablets. Which action will the nurse plan to take first? a. Administer activated charcoal. b. Insert a large-bore orogastric tube. c. Prepare a 60-mL syringe with saline. d. Assist with intubation of the patient.

D In an unresponsive patient, intubation is done before gastric lavage and activated charcoal administration to prevent aspiration. The other actions will be implemented after intubation.

During the primary survey of a patient with multiple traumatic injuries, the nurse observes that the patient's right pedal pulses are absent and the leg is swollen. Which of these actions will the nurse take next? a. Assess further for a cause of the decreased circulation. b. Send blood to the lab for a complete blood count (CBC). c. Finish the airway, breathing, circulation, disability survey. d. Initiate isotonic fluid infusion through two large-bore IV lines.

D The assessment data indicate that the patient may have arterial trauma and hemorrhage. When a possibly life-threatening injury is found during the primary survey, the nurse should immediately start interventions before proceeding with the survey. Although a CBC is indicated, administration of IV fluids should be started first. Completion of the primary survey and further assessment should be completed after the IV fluids are initiated.
