Chapter 68: Emergency and Disaster Nursing Lewis: Medical-Surgical Nursing, 10th Edition MULTIPLE CHOICE 1. During the primary assessment of a victim of a motor vehicle collision, the nurse determines

that the patient has an unobstructed airway. Which action should the nurse take next? a. Palpate extremities for bilateral pulses. b. Observe the patient’s respiratory effort. c. Check the patient’s level of consciousness. d. Examine the patient for any external bleeding. ANS: B

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 are also part of the initial survey but assessment of breathing should be done immediately after assessing for airway patency.

During the primary survey of a patient with severe leg trauma, the nurse observes that the

patient’s left pedal and posterior tibial pulses are absent and the entire leg is swollen. Which action will the nurse take next? a. Send blood to the lab for a complete blood count. b. Assess further for a cause of the decreased circulation. c. Finish the airway, breathing, circulation, disability survey. d. Start normal saline fluid infusion with a large-bore IV line. ANS: 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 complete blood count 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. DIF: Cognitive Level: Analyze (analysis) REF: 1630 TOP: Nursing Process: Implementation MSC: NCLEX: Physiological Integrity 3. After the return of spontaneous circulation following the resuscitation of a patient who had a

cardiac arrest, therapeutic hypothermia is ordered. Which action will the nurse include in the plan of care? a. Initiate cooling per protocol. b. Avoid the use of sedative drugs. c. Check mental status every 15 minutes. d. Rewarm if temperature is below 91° F (32.8° C). ANS: A

When therapeutic hypothermia is used postresuscitation, external cooling devices or cold normal saline infusions are used to rapidly lower body temperature to 89.6° F to 93.2° F (32° C to 34° C). Because hypothermia will decrease brain activity, assessing mental status every 15 minutes is not done at this stage. Sedative drugs are given during therapeutic hypothermia. DIF: Cognitive Level: Apply (application) REF: 1634 TOP: Nursing Process: Planning MSC: NCLEX: Physiological Integrity 4. A patient who is unconscious after a fall from a ladder is transported to the emergency

department by emergency medical personnel. During the primary survey of the patient, the nurse should a. obtain a complete set of vital signs. b. obtain a Glasgow Coma Scale score. c. attach an electrocardiogram monitor. d. ask about chronic medical conditions. ANS: B

The Glasgow Coma Scale is included when assessing for disability during the primary survey. The other information is part of the secondary survey. DIF: Cognitive Level: Apply (application) REF: 1632 TOP: Nursing Process: Assessment MSC: NCLEX: Physiological Integrity 5. A 19-yr-old patient is brought to the emergency department (ED) with multiple lacerations

and tissue avulsion of the left hand. When asked about tetanus immunization, the patient denies having any previous vaccinations. The nurse will anticipate giving a. tetanus immunoglobulin (TIG) only. b. TIG and tetanus-diphtheria toxoid (Td). c. tetanus-diphtheria toxoid and pertussis vaccine (Tdap) only. d. TIG and tetanus-diphtheria toxoid and pertussis vaccine (Tdap). ANS: D

For an adult with no previous tetanus immunizations, TIG and Tdap are recommended. The other immunizations are not sufficient for this patient. DIF: Cognitive Level: Apply (application) REF: 1634 TOP: Nursing Process: Planning MSC: NCLEX: Health Promotion and Maintenance 6. A patient who has experienced blunt abdominal trauma during a motor vehicle collision is

complaining of increasing abdominal pain. The nurse will plan to teach the patient about the purpose of a. peritoneal lavage. b. abdominal ultrasonography. c. nasogastric (NG) tube placement. d. magnetic resonance imaging (MRI). ANS: B

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 the diagnosis of intraabdominal bleeding.

treated in the emergency department (ED). The nurse determines that discharge teaching has been effective when the patient makes which statement? a. “I’ll 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 need to drink extra fluids when working outside in hot weather.” d. “I’ll move to a cool environment if I notice that I’m feeling confused” ANS: C

Oral fluids and electrolyte replacement 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 drugs 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.

A 22-yr-old patient who experienced a drowning accident in a local pool, but now is awake

and breathing spontaneously, is admitted for observation. Which assessment will be most important for the nurse to take during the observation period? a. Auscultate heart sounds. c. Auscultate breath sounds. b. Palpate peripheral pulses. d. Check mental orientation. ANS: C

Because pulmonary edema is a common complication after drowning, the nurse should assess the breath sounds frequently. The other information also will be obtained by the nurse, but it is not as pertinent to the patient’s admission diagnosis. DIF: Cognitive Level: Analyze (analysis) REF: 1640 TOP: Nursing Process: Implementation MSC: NCLEX: Physiological Integrity 9. When planning the response to the potential use of smallpox as a biological weapon, the

emergency department (ED) nurse manager will plan to obtain adequate quantities of c. antibiotics. d. whole blood.

a. vaccine. b. atropine. ANS: A

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 rewarming a patient who arrived in the emergency department (ED) with a temperature

of 87° F (30.6° C), which finding indicates that the nurse should discontinue active rewarming?

a. b. c. d.

The patient begins to shiver. The BP decreases to 86/42 mm Hg. The patient develops atrial fibrillation. The core temperature is 94° F (34.4° C).

ANS: D

A core temperature of at least 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. DIF: Cognitive Level: Apply (application) REF: 1634 TOP: Nursing Process: Evaluation MSC: NCLEX: Physiological Integrity 11. When assessing an older patient admitted to the emergency department (ED) with a broken

arm and facial bruises, the nurse observes several additional bruises in various stages of healing. Which statement or question by the nurse should be first? a. “You should not go home.” b. “Do you feel safe at home?” c. “Would you like to see a social worker?” d. “I need to report my concerns to the police.” ANS: B

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. A social worker or police report may be appropriate once further assessment is completed. DIF: Cognitive Level: Analyze (analysis) REF: 1644 TOP: Nursing Process: Implementation MSC: NCLEX: Psychosocial Integrity 12. A patient arrives in the emergency department (ED) several hours after taking “25 to 30”

acetaminophen (Tylenol) tablets. Which action will the nurse plan to take? a. Give N-acetylcysteine. b. Discuss the use of chelation therapy. c. Start oxygen using a non-rebreather mask. d. Have the patient drink large amounts of water. ANS: 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. DIF: Cognitive Level: Understand (comprehension) REF: 1643 TOP: Nursing Process: Planning MSC: NCLEX: Physiological Integrity 13. A triage nurse in a busy emergency department (ED) assesses a patient who complains of 7/10

abdominal pain and states, “I had a temperature of 103.9° F (39.9° C) at home.” The nurse’s first action should be to a. assess the patient’s current vital signs. b. give acetaminophen (Tylenol) per agency protocol. c. ask the patient to provide a clean-catch urine for urinalysis. d. tell the patient that it will be 1 to 2 hours before seeing a health care provider.

ANS: 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 appropriate, but this would be done after the vital signs are taken. The nurse will not give acetaminophen before confirming a current temperature elevation.

The emergency department (ED) triage nurse is assessing four victims involved in a motor

vehicle collision. Which patient has the highest priority for treatment? a. A patient with no pedal pulses b. A patient with an open femur fracture c. A patient with bleeding facial lacerations d. A patient with paradoxical chest movement ANS: D

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

The following interventions are part of the 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. Apply ice packs to both hands. c. Apply calamine lotion to itching areas. d. Give diphenhydramine (Benadryl) 50 mg PO. ANS: A

The patient’s rings should be removed first because it might not be possible to remove them if swelling develops. The other orders should also be implemented as rapidly as possible after the nurse has removed the jewelry. DIF: Cognitive Level: Analyze (analysis) REF: 1640 OBJ: Special Questions: Prioritization TOP: Nursing Process: Implementation MSC: NCLEX: Physiological Integrity 16. Gastric lavage and administration of activated charcoal are ordered for an unconscious patient

who has been admitted to the emergency department (ED) after ingesting 30 lorazepam (Ativan) tablets. Which prescribed action should the nurse plan to do first? a. Insert a large-bore orogastric tube. b. Assist with intubation of the patient. c. Prepare a 60-mL syringe with saline.

d. Give first dose of activated charcoal. ANS: B

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. DIF: Cognitive Level: Analyze (analysis) REF: 1630 OBJ: Special Questions: Prioritization TOP: Nursing Process: Planning MSC: NCLEX: Physiological Integrity 17. A patient arrives in the emergency department (ED) after topical exposure to powdered lime

at work. Which action should the nurse take first? a. Obtain the patient’s vital signs. b. Obtain a baseline complete blood count. c. Decontaminate the patient by showering with water. d. Brush off any visible powder on the skin and clothing. ANS: D

The initial action should be to protect staff members and decrease the patient’s exposure to the toxin by decontamination. Patients exposed to powdered lime should not be showered; instead, any and all visible powder should be brushed off. The other actions can be done after the decontamination is completed. DIF: Cognitive Level: Analyze (analysis) REF: 1643 OBJ: Special Questions: Prioritization TOP: Nursing Process: Implementation MSC: NCLEX: Physiological Integrity 18. An unresponsive 79-yr-old patient is admitted to the emergency department (ED) during a

summer heat wave. The patient’s core temperature is 105.4° F (40.8° C), blood pressure (BP) is 88/50 mm Hg, and pulse is 112 beats/min. The nurse will plan to a. apply wet sheets and a fan to the patient. b. provide O2 at 2 L/min with a nasal cannula. c. start lactated Ringer’s solution at 1000 mL/hr. d. give acetaminophen (Tylenol) rectal suppository. ANS: A

The priority intervention is to cool the patient. Antipyretics are not effective in decreasing temperature in heat stroke and 100% O2 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. DIF: Cognitive Level: Apply (application) REF: 1637 TOP: Nursing Process: Planning MSC: NCLEX: Physiological Integrity 19. An unresponsive patient is admitted to the emergency department (ED) after falling through

the ice while ice skating. Which assessment will the nurse obtain first? a. Pulse c. Breath sounds b. Heart rhythm d. Body temperature ANS: A

The priority assessment in an unresponsive patient relates to CAB (circulation, airway, breathing) so a pulse check should be performed first. While assessing the pulse, the nurse should look for signs of breathing. The other data will also be collected rapidly but are not as essential as determining if there is a pulse.

Following an earthquake, patients are triaged by emergency medical personnel and

transported to the emergency department (ED). Which patient will the nurse need to assess first? a. A patient with a red tag c. A patient with a black tag b. A patient with a blue tag d. A patient with a yellow tag ANS: 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.

Family members are in the patient’s room when the patient has a cardiac arrest and the staff

start resuscitation measures. Which action should the nurse take next? a. Keep the family in the room and assign a staff member to explain the care given

and answer questions. b. Ask the family to wait outside the patient’s room with a designated staff member

to provide emotional support. c. Ask the family members whether they would prefer to remain in the patient’s room

or wait outside the room. d. Tell the family members that patients are comforted by having family members

present during resuscitation efforts. ANS: 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 who has deep human bite wounds on the left hand is being treated in the urgent care

center. Which action will the nurse plan to take? a. Prepare to administer rabies immune globulin (BayRab). b. Assist the health care provider with suturing of the bite wounds. c. Teach the patient the reason for the use of prophylactic antibiotics. d. Keep the wounds dry until the health care provider can assess them. ANS: C

Because human bites of the hand frequently become infected, prophylactic antibiotics are usually prescribed to prevent infection. To minimize infection, deep bite wounds on the extremities are left open. Rabies immune globulin might be used after an animal bite. Initial treatment of bite wounds includes copious irrigation to help clean out contaminants and microorganisms. DIF: Cognitive Level: Apply (application) REF: 1642 TOP: Nursing Process: Planning MSC: NCLEX: Physiological Integrity 23. The urgent care center protocol for tick bites includes the following actions. Which action will

the nurse take first when caring for a patient with a tick bite? a. Use tweezers to remove any remaining ticks. b. Check the vital signs, including temperature. c. Give doxycycline (Vibramycin) 100 mg orally. d. Obtain information about recent outdoor activities. ANS: A

Because neurotoxic venom is released as long as the tick is attached to the patient, the initial action should be to remove any ticks using tweezers or forceps. The other actions are also appropriate, but the priority is to minimize venom release.

Which interventions will the nurse plan for a comatose patient who is to begin therapeutic

hypothermia (select all that apply)? a. Assist with endotracheal intubation. b. Insert an indwelling urinary catheter. c. Begin continuous cardiac monitoring. d. Obtain an order to restrain the patient. e. Prepare to give sympathomimetic drugs. ANS: A, B, C

Cooling can produce dysrhythmias, so the patient’s heart rhythm should be continuously monitored and dysrhythmias treated if necessary. Bladder catheterization and endotracheal intubation are needed during cooling. Sympathomimetic drugs tend to stimulate the heart and increase the risk for fatal dysrhythmias such as ventricular fibrillation. Patients receiving therapeutic hypothermia are comatose o...
