Which preventive actions by the nurse will help limit the development of systemic inflammatory response syndrome (SIRS) in patients admitted to the hospital (select all that apply)? Use aseptic technique when caring for invasive lines or devices. Ambulate postoperative patients as soon as possible after surgery. Remove indwelling urinary catheters as soon as possible after surgery. Advocate for parenteral nutrition for patients who cannot take oral feedings. Administer prescribed antibiotics within 1 hour for patients with possible sepsis.

ANS: A, B, C, E Because sepsis is the most frequent etiology for SIRS, measures to avoid infection such as removing indwelling urinary catheters as soon as possible, use of aseptic technique, and early ambulation should be included in the plan of care. Adequate nutrition is important in preventing SIRS. Enteral, rather than parenteral nutrition is preferred when patients are unable to take oral feedings because enteral nutrition helps maintain the integrity of the intestine, thus decreasing infection risk. Antibiotics should be administered within 1 hour after being prescribed to decrease the risk of sepsis progressing to SIRS.

A patient with suspected neurogenic shock after a diving accident has arrived in the emergency department. A cervical collar is in place. Which actions should the nurse take (select all that apply)? Prepare to administer atropine IV. Obtain baseline body temperature. Infuse large volumes of lactated Ringers solution. Provide high-flow oxygen (100%) by non-rebreather mask. Prepare for emergent intubation and mechanical ventilation.

ANS: A, B, D, E All of the actions are appropriate except to give large volumes of lactated Ringers solution. The patient with neurogenic shock usually has a normal blood volume, and it is important not to volume overload the patient. In addition, lactated Ringers solution is used cautiously in all shock situations because the failing liver cannot convert lactate to bicarbonate.

An example of a sign of renal failure is a urine output, despite volume resuscitation, of: a. 0.3mL/kg/hr b. 0.6mL/kg/hr c. 0.9 mL/kg/hr d. 1.2mL/kg/hr

ANS: B

Two of the SIRS criteria plus a known or suspected infection is considered which stage is the progression of sepsis? a. Severe sepsis b. Sepsis c. Septic shock d. Presepsis

ANS: B

24. After change-of-shift report in the progressive care unit, who should the nurse care for first? Patient who had an inferior myocardial infarction 2 days ago and has crackles in the lung bases Patient with suspected urosepsis who has new orders for urine and blood cultures and antibiotics Patient who had a T5 spinal cord injury 1 week ago and currently has a heart rate of 54 beats/minute Patient admitted with anaphylaxis 3 hours ago who now has clear lung sounds and a blood pressure of 108/58 mm Hg

ANS: B Antibiotics should be administered within the first hour for patients who have sepsis or suspected sepsis in order to prevent progression to systemic inflammatory response syndrome (SIRS) and septic shock. The data on the other patients indicate that they are more stable. Crackles heard only at the lung bases do not require immediate intervention in a patient who has had a myocardial infarction. Mild bradycardia does not usually require atropine in patients who have a spinal cord injury. The findings for the patient admitted with anaphylaxis indicate resolution of bronchospasm and hypotension.

9. Which finding is the best indicator that the fluid resuscitation for a patient with hypovolemic shock has been effective? a. Hemoglobin is within normal limits. b. Urine output is 60 mL over the last hour. c. Central venous pressure (CVP) is normal. d. Mean arterial pressure (MAP) is 72 mm Hg.

ANS: B Assessment of end organ perfusion, such as an adequate urine output, is the best indicator that fluid resuscitation has been successful. The hemoglobin level, CVP, and MAP are useful in determining the effects of fluid administration, but they are not as useful as data indicating good organ perfusion.

27. Which information obtained by the nurse caring for a patient with thrombocytopenia should be immediately communicated to the health care provider? a. The platelet count is 52,000/L. b. The patient is difficult to arouse. c. There are purpura on the oral mucosa. d. There are large bruises on the patients back.

ANS: B Difficulty in arousing the patient may indicate a cerebral hemorrhage, which is life threatening and requires immediate action. The other information should be documented and reported but would not be unusual in a patient with thrombocytopenia.

22. The following interventions are ordered by the health care provider for a patient who has respiratory distress and syncope after eating strawberries. Which will the nurse complete first? Start a normal saline infusion. Give epinephrine (Adrenalin). Start continuous ECG monitoring. Give diphenhydramine (Benadryl).

ANS: B Epinephrine rapidly causes peripheral vasoconstriction, dilates the bronchi, and blocks the effects of histamine and reverses the vasodilation, bronchoconstriction, and histamine release that cause the symptoms of anaphylaxis. The other interventions are also appropriate but would not be the first ones completed.

A patient is experiencing pulmonary edema as an exacerbation of chronic left-sided heart failure. The nurses assesses the patient for which of the following manifestations? a. Weight loss b. Bilateral crackles c. Distended neck veins d. Peripheral pitting edema

ANS: B Pulmonary edema is the basis of ARDS - we see a component of pulmonary edema when pt goes into ARDS.

10. Which intervention will the nurse include in the plan of care for a patient who has cardiogenic shock? a. Check temperature every 2 hours. b. Monitor breath sounds frequently. c. Maintain patient in supine position. d. Assess skin for flushing and itching.

ANS: B Since pulmonary congestion and dyspnea are characteristics of cardiogenic shock, the nurse should assess the breath sounds frequently. The head of the bed is usually elevated to decrease dyspnea in patients with cardiogenic shock. Elevated temperature and flushing or itching of the skin are not typical of cardiogenic shock. DIF: Cognitive Level: Apply (application) REF: 1589 TOP: Nursing Process: Implementation

5. After receiving 2 L of normal saline, the central venous pressure for a patient who has septic shock is 10 mm Hg, but the blood pressure is still 82/40 mm Hg. The nurse will anticipate an order for a. nitroglycerine (Tridil). b. norepinephrine (Levophed). c. sodium nitroprusside (Nipride). d. methylprednisolone (Solu-Medrol).

ANS: B When fluid resuscitation is unsuccessful, vasopressor drugs are administered to increase the systemic vascular resistance (SVR) and blood pressure, and improve tissue perfusion. Nitroglycerin would decrease the preload and further drop cardiac output and BP. Methylprednisolone (Solu-Medrol) is considered if blood pressure does not respond first to fluids and vasopressors. Nitroprusside is an arterial vasodilator and would further decrease SVR. DIF: Cognitive Level: Apply (application) REF: 1599 TOP: Nursing Process: Planning

17. The nurse is caring for a patient who has septic shock. Which assessment finding is most important for the nurse to report to the health care provider? a. Blood pressure (BP) 92/56 mm Hg b. Skin cool and clammy c. Oxygen saturation 92% d. Heart rate 118 beats/minute

ANS: B Because patients in the early stage of septic shock have warm and dry skin, the patients cool and clammy skin indicates that shock is progressing. The other information will also be reported, but does not indicate deterioration of the patients status. DIF: Cognitive Level: Apply (application) REF: 1594 OBJ: Special Questions: Prioritization TOP: Nursing Process: Assessment

7. A patient with cardiogenic shock has the following vital signs: BP 102/50, pulse 128, respirations 28. The pulmonary artery wedge pressure (PAWP) is increased and cardiac output is low. The nurse will anticipate an order for which medication? a. 5% human albumin b. Furosemide (Lasix) IV c. Epinephrine (Adrenalin) drip d. Hydrocortisone (Solu-Cortef)

ANS: B The PAWP indicates that the patients preload is elevated, and furosemide is indicated to reduce the preload and improve cardiac output. Epinephrine would further increase heart rate and myocardial oxygen demand. 5% human albumin would also increase the PAWP. Hydrocortisone might be considered for septic or anaphylactic shock. DIF: Cognitive Level: Apply (application) REF: 1601 TOP: Nursing Process: Planning

A patient recovering from second-and third degree burns over 30% of his body and is now ready for discharge. The first action the nurse should take when meeting with the patient would be to? a. Arrange a return-to-the clinic appointment and prescription for pain medication. b. Teach the patient and the caregiver proper wound care to be performed at home. c. Review the patient's current health care status and readiness for discharge to home. d. Give the patient written discharge information and websites for additional information for burn survivors.

ANS: C

Septic shock is caused by which source? a. Allergens b. Loss of sympathetic tone c. Microorganisms d. Non-immunologic activation of mast cells and basophils

ANS: C

Which kind of shock occurs from inadequate fluid volume in the intravascular space? A. Anaphylactic B. Cardiogenic C. Hypovolemic D. Neurogenic

ANS: C

8. The emergency department (ED) nurse receives report that a patient involved in a motor vehicle crash is being transported to the facility with an estimated arrival in 1 minute. In preparation for the patients arrival, the nurse will obtain a. hypothermia blanket. b. lactated Ringers solution. c. two 14-gauge IV catheters. d. dopamine (Intropin) infusion.

ANS: C A patient with multiple trauma may require fluid resuscitation to prevent or treat hypovolemic shock, so the nurse will anticipate the need for 2 large bore IV lines to administer normal saline. Lactated Ringers solution should be used cautiously and will not be ordered until the patient has been assessed for possible liver abnormalities. Vasopressor infusion is not used as the initial therapy for hypovolemic shock. Patients in shock need to be kept warm not cool. DIF: Cognitive Level: Apply (application) REF: 1597 TOP: Nursing Process: Planning

23. Which finding about a patient who is receiving vasopressin (Pitressin) to treat septic shock is most important for the nurse to communicate to the health care provider? The patients urine output is 18 mL/hr. The patients heart rate is 110 beats/minute. The patient is complaining of chest pain. The patients peripheral pulses are weak.

ANS: C Because vasopressin is a potent vasoconstrictor, it may decrease coronary artery perfusion. The other information is consistent with the patients diagnosis and should be reported to the health care provider but does not indicate a need for a change in therapy.

3. A 19-year-old patient with massive trauma and possible spinal cord injury is admitted to the emergency department (ED). Which assessment finding by the nurse will help confirm a diagnosis of neurogenic shock? a. Inspiratory crackles. b. Cool, clammy extremities. c. Apical heart rate 45 beats/min. d. Temperature 101.2 F (38.4 C).

ANS: C Neurogenic shock is characterized by hypotension and bradycardia. The other findings would be more consistent with other types of shock. DIF: Cognitive Level: Understand (comprehension) REF: 1590 TOP: Nursing Process: Assessment

4. An older patient with cardiogenic shock is cool and clammy and hemodynamic monitoring indicates a high systemic vascular resistance (SVR). Which intervention should the nurse anticipate doing next? a. Increase the rate for the dopamine (Intropin) infusion. b. Decrease the rate for the nitroglycerin (Tridil) infusion. c. Increase the rate for the sodium nitroprusside (Nipride) infusion. d. Decrease the rate for the 5% dextrose in normal saline (D5/.9 NS) infusion.

ANS: C Nitroprusside is an arterial vasodilator and will decrease the SVR and afterload, which will improve cardiac output. Changes in the D5/.9 NS and nitroglycerin infusions will not directly decrease SVR. Increasing the dopamine will tend to increase SVR. DIF: Cognitive Level: Apply (application) REF: 1600 TOP: Nursing Process: Planning

21. The patient with neurogenic shock is receiving a phenylephrine (Neo-Synephrine) infusion through a right forearm IV. Which assessment finding obtained by the nurse indicates a need for immediate action? The patients heart rate is 58 beats/minute. The patients extremities are warm and dry. The patients IV infusion site is cool and pale. The patients urine output is 28 mL over the last hour.

ANS: C The coldness and pallor at the infusion site suggest extravasation of the phenylephrine. The nurse should discontinue the IV and, if possible, infuse the medication into a central line. An apical pulse of 58 is typical for neurogenic shock but does not indicate an immediate need for nursing intervention. A 28-mL urinary output over 1 hour would require the nurse to monitor the output over the next hour, but an immediate change in therapy is not indicated. Warm, dry skin is consistent with early neurogenic shock, but it does not indicate a need for a change in therapy or immediate action.

20. A patient who has been involved in a motor vehicle crash arrives in the emergency department (ED) with cool, clammy skin; tachycardia; and hypotension. Which intervention ordered by the health care provider should the nurse implement first? Insert two large-bore IV catheters. Initiate continuous electrocardiogram (ECG) monitoring. Provide oxygen at 100% per non-rebreather mask. Draw blood to type and crossmatch for transfusions.

ANS: C The first priority in the initial management of shock is maintenance of the airway and ventilation. ECG monitoring, insertion of IV catheters, and obtaining blood for transfusions should also be rapidly accomplished but only after actions to maximize oxygen delivery have been implemented.

25. After reviewing the information shown in the accompanying figure for a patient with pneumonia and sepsis, which information is most important to report to the health care provider? Temperature and IV site appearance Oxygen saturation and breath sounds Platelet count and presence of petechiae Blood pressure, pulse rate, respiratory rate.

ANS: C The low platelet count and presence of petechiae suggest that the patient may have disseminated intravascular coagulation and that multiple organ dysfunction syndrome (MODS) is developing. The other information will also be discussed with the health care provider but does not indicate that the patients condition is deteriorating or that a change in therapy is needed immediately.

36. A patient with possible disseminated intravascular coagulation arrives in the emergency department with a blood pressure of 82/40, temperature 102 F (38.9 C), and severe back pain. Which physician order will the nurse implement first? a. Administer morphine sulfate 4 mg IV. b. Give acetaminophen (Tylenol) 650 mg. c. Infuse normal saline 500 mL over 30 minutes. d. Schedule complete blood count and coagulation studies.

ANS: C The patients blood pressure indicates hypovolemia caused by blood loss and should be addressed immediately to improve perfusion to vital organs. The other actions also are appropriate and should be rapidly implemented, but improving perfusion is the priority for this patient.

12. A nurse is assessing a patient who is receiving a nitroprusside (Nipride) infusion to treat cardiogenic shock. Which finding indicates that the medication is effective? a. No new heart murmurs b. Decreased troponin level c. Warm, pink, and dry skin d. Blood pressure 92/40 mm Hg

ANS: C Warm, pink, and dry skin indicates that perfusion to tissues is improved. Since nitroprusside is a vasodilator, the blood pressure may be low even if the medication is effective. Absence of a heart murmur and a decrease in troponin level are not indicators of improvement in shock. DIF: Cognitive Level: Apply (application) REF: 1600 TOP: Nursing Process: Evaluation

While performing triage in the emergency department, the nurse determines that which of the following patients should be seen first? a. A patient with a deformed leg indicating a fractured tibia; blood pressure 110/60 mm Hg, pulse 86 beats/min, respirations 18 breaths/min. b. A patient with burns on the face and chest; blood pressure 120/80 mm Hg, pulse 92 beats/min, respirations 24 breaths/min. c. A patient with type 1 diabetes in ketoacidosis; blood pressure 100/60 mm Hg, pulse 100 beats/min, respirations 32 breaths/min. d. A patient with a respiratory infection with a cough productive of greenish sputum; blood pressure 128/86 mm Hg, pulse 88 beats/min, respirations 26 breaths/min.

ANS: C because of low BP and high pulse and kussmaul respirations = shock Disaster Planning PP

A patient admitted to the hospital from a long-term care facility appears to be in the late stage of shock with systemic inflammatory response syndrome (SIRS). Which of the following orders implemented by the nurse has the highest priority? a. Insert an indwelling urinary catheter. b. Insert two large-bore intravenous catheters. c. Administer 0.9% normal saline at 100 mL/hr. d. Administer 100% oxygen by non-rebreather mask.

ANS: D

What occurs during the refractory stage of shock? A. Cardiac output (CO) is decreased, and tissue perfusion is threatened. B. Compensatory mechanisms begin failing. C. Homeostatic mechanisms begin to work. D. Shock becomes unresponsive to therapy.

ANS: D

12. A patient who has been receiving a heparin infusion and warfarin (Coumadin) for a deep vein thrombosis (DVT) is diagnosed with heparin-induced thrombocytopenia (HIT) when her platelet level drops to 110,000/L. Which action will the nurse include in the plan of care? a. Use low-molecular-weight heparin (LMWH) only. b. Administer the warfarin (Coumadin) at the scheduled time. c. Teach the patient about the purpose of platelet transfusions. d. Discontinue heparin and flush intermittent IV lines using normal saline.

ANS: D All heparin is discontinued when the HIT is diagnosed. The patient should be instructed to never receive heparin or LMWH. Warfarin is usually not given until the platelet count has returned to 150,000/L. The platelet count does not drop low enough in HIT for a platelet transfusion, and platelet transfusions increase the risk for thrombosis.

When monitoring initial fluid replacement for the patient with 40% TBSA deep partial-thickness and full-thickness burns, which of the following findings is of most concern to the nurse? a. Urine output of 35 ml/hr b. Serum K+ of 4.5 mEq/L c. Decreased bowel sounds d. Blood pressure of 86/72 mm Hg

ANS: D No pulse pressure so no circulation.

6. To evaluate the effectiveness of the pantoprazole (Protonix) ordered for a patient with systemic inflammatory response syndrome (SIRS), which assessment will the nurse perform? a. Auscultate bowel sounds. b. Palpate for abdominal pain. c. Ask the patient about nausea. d. Check stools for occult blood.

ANS: D Proton pump inhibitors are given to decrease the risk for stress ulcers in critically ill patients. The other assessments also will be done, but these will not help in determining the effectiveness of the pantoprazole administration. DIF: Cognitive Level: Apply (application) REF: 1602 TOP: Nursing Process: Evaluation

During the emergent phase of burn injury, the nurse assesses for the presence of hypovolemia. In burns, hypovolemia occurs primarily as a result of a. blood loss from injured tissue. b. third spacing of fluid into fluid-filled vesicles. c. evaporation of fluid from denuded body surfaces. d. capillary permeability with fluid shift to the interstitium.

ANS: D This is why swelling with burns is such a huge complication and needs to be assessed at all times.

Assessment of a male patient during the primary survey indicates delayed capillary refill of the extremities. He cannot explain the events before admission to the ED. Which action should the nurse take immediately? a. Apply leads to the patient's chest to initiate ECG monitoring. b. Insert one or two large-bore IV catheters to start IV fluid resuscitation. c. Continue the primary survey to complete a brief neurologic examination. d. Initiate pulse oximetry by placing a monitoring device on the patient's index finger.

ANS: D because it deals with airway!! B says one OR two; we NEED 2!! Disaster Planning PP

13. Which assessment information is most important for the nurse to obtain to evaluate whether treatment of a patient with anaphylactic shock has been effective? a. Heart rate b. Orientation c. Blood pressure d. Oxygen saturation

ANS: D Because the airway edema that is associated with anaphylaxis can affect airway and breathing, the oxygen saturation is the most critical assessment. Improvements in the other assessments will also be expected with effective treatment of anaphylactic shock. DIF: Cognitive Level: Apply (application) REF: 1602 TOP: Nursing Process: Evaluation

16. When the nurse educator is evaluating the skills of a new registered nurse (RN) caring for patients experiencing shock, which action by the new RN indicates a need for more education? a. Placing the pulse oximeter on the ear for a patient with septic shock b. Keeping the head of the bed flat for a patient with hypovolemic shock c. Increasing the nitroprusside (Nipride) infusion rate for a patient with a high SVR d. Maintaining the room temperature at 66 to 68 F for a patient with neurogenic shock

ANS: D Patients with neurogenic shock may have poikilothermia. The room temperature should be kept warm to avoid hypothermia. The other actions by the new RN are appropriate. DIF: Cognitive Level: Apply (application) REF: 1590 OBJ: Special Questions: Delegation TOP: Nursing Process: Evaluation

15. Which laboratory result will the nurse expect to show a decreased value if a patient develops heparin- induced thrombocytopenia (HIT)? a. Prothrombin time b. Erythrocyte count c. Fibrinogen degradation products d. Activated partial thromboplastin time

ANS: D Platelet aggregation in HIT causes neutralization of heparin, so that the activated partial thromboplastin time will be shorter and more heparin will be needed to maintain therapeutic levels. The other data will not be affected by HIT. DIF: Cognitive Level: Apply (application) REF: 625 TOP: Nursing Process: Assessment

A patient with a gunshot wound to the abdomen is being treated for hypovolemic shock and septic shock. TO monitor the patient for early organ damage associated with MODS, what is most important for the nurse to assess? a. urine output b. breath sounds c. peripheral cirulation d. central venous pressure

B

Which patient manifestations confirm the development of MODS? a. upper GI bleeding, GCS score of 7, and Hct of 25% b. elevated serum bilirubin, serum creatinine of 3.8, and platelet count of 15,000 c. urine output of 30 ml/hr, BUN of 45, and WBC count of 1120 d. respiratory rate of 45, PaCO2 of 60, and chest x-ray with bilateral diffuse patchy infiltrates.

B

The patient has hypovolemic shock. By compensatory mechanisms, the decreased blood pressure (BP) has led to decreased capillary hydrostatic pressure, activation of the sympathetic nervous system and α- and β-adrenergic stimulation, decreased blood flow, and increased cardiac output (CO). In what order should the next pathophysiologic mechanisms of the compensated stage of hypovolemic shock occur? (Answer with a letter followed by a comma and a space (e.g. A, B, C, D).) a. Increased ADH leads to renal water reabsorption and increased blood volume. b. Decreased kidney perfusion leads to renin released and increased angiotensin I. c. Increased renal sodium reabsorption leads to increased serum osmolality that leads to release of ADH. d. Increased angiotensin II leads to aldosterone secretion and results in increased renal sodium reabsorption. e. Increased angiotensin II leads to venous and arterial vasoconstriction, increased venous return to the heart, and increased BP.

B, D, E, C, A After the α- and β-adrenergic stimulation occurs in hypovolemic shock, angiotensin I is stimulated by decreased kidney perfusion and renin release. Increased angiotensin II leads to increased serum osmolality, the release of antidiuretic hormone (ADH), and aldosterone secretion that reabsorbs sodium. The increased ADH also increases renal water reabsorption, which increases blood volume.

A nurse witnesses a patient going into pulmonary edema. The patient exhibits respiratory distress, but the blood pressure is stable at this time. While waiting for help to arrive, the nurse performs the following actions in which order of priority? a. Rechecks vital signs b. Places the patient in high fowler's position c. Calls the respiratory therapy department for a ventilator d. Places the patient on a pulse oximeter and cardiac monitor e. Begins the patient's oxygen at 2 liters by nasal cannula as needed f. Administers the patient morphine sulfate intravenous injection as needed

B, E, D, A, F, C (D then A because intervention then reassessment!) MSC increases O2 supply by vasodilation!!!

A patient is being treated for cardiogenic shock. Which statement below best describes this condition? Select all that apply:*' A. "The patient will experience an increase in cardiac output due to an increase in preload and afterload." B. "A patient with this condition will experience decreased cardiac output and decreased tissue perfusion." C. "This condition occurs because the heart has an inadequate blood volume to pump." D. "Cardiogenic shock leads to pulmonary edema."

B. "A patient with this condition will experience decreased cardiac output and decreased tissue perfusion." D. "Cardiogenic shock leads to pulmonary edema."

You're precepting a new nurse. You ask the new nurse to list the purpose of why a patient with cardiogenic shock may benefit from an intra-aortic balloon pump. What responses below indicate the new nurse understands the purpose of an intra-aortic balloon pump? Select all that apply:* A. "This device increases the cardiac afterload, which will increase cardiac output." B. "This device will help increase blood flow to the coronary arteries." C. "The balloon pump will help remove extra fluid from the heart and lungs." D. "The balloon pump will help increase cardiac output."

B. "This device will help increase blood flow to the coronary arteries." D. "The balloon pump will help increase cardiac output."

A patient is on IV Norepinephrine for treatment of septic shock. Which statement is FALSE about this medication? A. "The nurse should titrate this medication to maintain a MAP of 65 mmHg or greater." B. "This medication causes vasodilation and decreases systemic vascular resistance." C. "It is used when fluid replacement is not unsuccessful." D. "It is considered a vasopressor."

B. "This medication causes vasodilation and decreases systemic vascular resistance."

If a patient has a blood volume of 5 Liters and loses 2 Liters, what is the percentage amount of volume loss this patient has experienced?* A. 25% B. 40% C. 30% D. 10%

B. 40%

You're working on a neuro unit. Which of your patients below are at risk for developing neurogenic shock? Select all that apply: A. A 36-year-old with a spinal cord injury at L4. B. A 42-year-old who has spinal anesthesia. C. A 25-year-old with a spinal cord injury above T6. D. A 55-year-old patient who is reporting seeing green halos while taking Digoxin.

B. A 42-year-old who has spinal anesthesia. C. A 25-year-old with a spinal cord injury above T6.

A 50-yr-old woman with a suspected brain tumor is scheduled for a CT scan with contrast media. The nurse notifies the physician that the patient reported an allergy to shellfish. Which response by the physician should the nurse question? A. Infuse IV diphenhydramine before the procedure. B. Administer lorazepam (Ativan) before the procedure. C. Complete the CT scan without the use of contrast media. D. Premedicate with hydrocortisone sodium succinate (Solu-Cortef).

B. Administer lorazepam (Ativan) before the procedure. An individual with an allergy to shellfish is at an increased risk to develop anaphylactic shock if contrast media is injected for a CT scan. To prevent anaphylactic shock, the nurse should always confirm the patient's allergies before diagnostic procedures (e.g., CT scan with contrast media). Appropriate interventions may include cancelling the procedure, completing the procedure without contrast media, or premedication with diphenhydramine or hydrocortisone. IV fluids may be given to promote renal clearance of the contrast media and prevent renal toxicity and acute kidney injury. The use of an antianxiety agent such as lorazepam would not be effective in preventing an allergic reaction to the contrast media.

A patient has a 10% loss of their blood volume. Select all the signs and symptoms this patient may present with?* A. Cool, clammy skin B. Blood pressure within normal limits C. Anxiety D. Capillary refill less than 2 seconds E. Urinary output greater than 30 mL/hr F. Mild tachycardia

B. Blood pressure within normal limits D. Capillary refill less than 2 seconds E. Urinary output greater than 30 mL/h

Your patient is started on an IV antibiotic to treat a severe infection. During infusion, the patient uses the call light to notify you that she feels a tight sensation in her throat and it's making it hard to breathe. You immediately arrive to the room and assess the patient. While auscultating the lungs you note wheezing. You also notice that the patient is starting to scratch the face and arms, and on closer inspection of the face you note redness and swelling that extends down to the neck and torso. The patient's vital signs are the following: blood pressure 89/62, heart rate 118 bpm, and oxygen saturation 88% on room air. You suspect anaphylactic shock. Select all the appropriate interventions for this patient: A. Slow down the antibiotic infusion B. Call a rapid response C. Place the patient on oxygen D.

Patients in septic shock require large amounts of fluid replacement and may require frequent fluid boluses to maintain circulation. Antibiotics are an important component of therapy for patients with septic shock. They should be started after cultures (e.g., blood, urine) are obtained and within the first hour of septic shock. Oxygenating the tissues is the top priority in sepsis, so efforts to wean septic patients from mechanical ventilation halt until sepsis is resolving. Additional respiratory support may be needed during sepsis. Although cool and clammy skin is present in other early shock states, the patient in early septic shock may feel warm and flushed because of a hyperdynamic state.

The SvO2 decreases when more oxygen is used by the cells, as in activity or hypermetabolism. All of the other values indicate an improvement in the patient's condition.

A patient with hypovolemic shock is receiving lactated Ringer's solution for fluid replacement therapy. During this therapy, which laboratory result is most important for the nurse to monitor? a. Serum pH b. Serum sodium c. Serum potassium d. Hemoglobin (Hgb) and hematocrit (Hct)

a. Lactated Ringer's solution may increase lactate levels, which a damaged liver cannot convert to bicarbonate. This may intensify the metabolic lactic acidosis that occurs in progressive shock, necessitating careful attention to the patient's acid-base balance. Sodium and potassium levels as well as hemoglobin (Hgb) and hematocrit (Hct) levels should be monitored in all patients receiving fluid replacement therapy.

A 70-year-old patient is malnourished, has a history of type 2 diabetes mellitus, and is admitted from the nursing home with pneumonia. For which kind of shock should the nurse closely monitor this patient? a. Septic shock b. Neurogenic shock c. Cardiogenic shock d. Anaphylactic shock

a. Older adults with chronic diseases and malnourished or debilitated patients are at risk of developing septic shock, especially when they have an infection (e.g., pneumonia, urinary tract infection) or indwelling lines or catheters.

A common manifestation of the rapid progression of sepsis is: a. Tachycardia b. Hypertension c. Polyuria d. Bradypnea

a. Tachycardia

Appropriate treatment modalities for the management of cariogenic shock include (select all that apply): a. dobutamine to increase myocardial contractility b. vasopressors to increase systemic vascular resistance c. circulatory assist devices such as an intraortic balloon pump d. corticosteroids to stabilize the cell wall in the infarcted myocardium e. trendelenburg position to facilitate venous return and increased preload

a. dobutamine to increase myocardial contractility c. circulatory assist devices such as an intraortic balloon pump

a nurse is planning care for a client who has septic shock. which of the following actions is the priority for the nurse to take maintain adequate fluid volume with IV infusions administer ABX Monitor hemodynamic status administer vasopressor medication

administer ABX

A patient with severe trauma has been treated for hypovolemic shock. The nurse recognizes that the patient is in the irreversible stage of shock when what is included in assessment findings? a. A lactic acidosis with a pH of 7.32 b. Marked hypotension and refractory hypoxemia c. Unresponsiveness that responds only to painful stimuli d. Profound vasoconstriction with absent peripheral pulses

b. During both the compensatory and the progressive stages of shock, the sympathetic nervous system is activated in an attempt to maintain CO and SVR. In the irreversible stage of shock, the sympathetic nervous system can no longer compensate to maintain homeostasis and a loss of vasomotor tone leading to profound hypotension affects perfusion to all vital organs, causing increasing cellular hypoxia, metabolic acidosis, and cellular death.

Which hemodynamic monitoring description of the identified shock is accurate? a. Tachycardia with hypertension is characteristic of neurogenic shock. b. In cardiogenic shock the patient will have an increased pulmonary artery wedge pressure (PAWP) and a decreased cardiac output (CO). c. Anaphylactic shock is characterized by increased systemic vascular resistance (SVR), decreased CO, and decreased PAWP. d. In septic shock, bacterial endotoxins cause vascular changes that result in increased SVR and decreased CO.

b. Hemodynamic monitoring in cardiogenic shock will reveal increased pulmonary artery wedge pressure (PAWP) and decreased CO. The characteristic signs of neurogenic shock are bradycardia and hypotension. Septic shock manifests with decreased systemic vascular resistance (SVR) and increased CO. Hypovolemic shock is characterized by increased SVR, decreased CO, and decreased PAWP.

What abnormal finding should the nurse expect to find in early compensatory shock? a. Metabolic acidosis b. Increased serum sodium c. Decreased blood glucose d. Increased serum potassium

b. In early compensatory shock, activation of the renin- angiotensin-aldosterone system stimulates the release of aldosterone, which causes sodium reabsorption and potassium excretion by the kidney, elevating serum sodium levels and decreasing serum potassium levels. Blood glucose levels are elevated during the compensatory stage of shock in response to catecholamine stimulation of the liver, which releases its glycogen stores in the form of glucose. Metabolic acidosis does not occur until the progressive stage of shock. At this stage compensatory mechanisms become ineffective and anaerobic cellular metabolism causes lactic acid production.

When shock occurs in a patient with pulmonary embolism or abdominal compartment syndrome, what type of shock would that be? a. Distributive shock b. Obstructive shock c. Cardiogenic shock d. Hypovolemic shock

b. Obstructive shock occurs when a physical obstruction impedes the filling or outflow of blood, resulting in reduced cardiac output (CO).

The nurse determines that a large amount of crystalloid fluids administered to a patient in septic shock is effective when hemodynamic monitoring reveals what? a. CO of 2.6 L/min b. CVP of 15 mm Hg c. PAWP of 4 mm Hg d. Heart rate (HR) of 106 bpm

b. The endpoint of fluid resuscitation in septic and hypovolemic shock is a central venous pressure (CVP) of 15 mm Hg or a PAWP of 10-12mmHg. The CO is too low and the heart rate is too high to indicate adequate fluid replacement.

The nurse suspects sepsis as a cause of shock when the laboratory test results indicate a. hypokalemia. b. thrombocytopenia. c. decreased hemoglobin. d. increased blood urea nitrogen (BUN)

b. Thrombocytopenia can occur. When sepsis is the cause of shock, endotoxin stimulates a cascade of inflammatory responses that start with the release of tumor necrosis factor (TNF) and interleukin-1 (IL-1), which stimulate other inflammatory mediators. The release of platelet- activating factor causes formation of microthrombi and vessel obstruction. There is vasodilation, increased capillary permeability, and neutrophil and platelet aggregation and adhesion to the endothelium. The process does not occur in other types of shock until late stages of shock.

78 y.o man has confusion and temperature of 104. He's diabetic with purulent drainage from his right heel. After infusion of 3L of NS, his assessment findings are BP 84/40, HR 110, Res 42 and shallow, CO 8L/min and PAWP 4mm. Patient is most likely in: a. sepsis b. septic shock c. multiple organ dysfunction syndrome d. SIRS

b. septic shock

Priority Decision: What is the priority nursing responsibility in the prevention of shock? a. Frequently monitoring all patients' vital signs b. Using aseptic technique for all invasive procedures c. Being aware of the potential for shock in all patients at risk d. Teaching patients health promotion activities to prevent shock

c. Prevention of shock necessitates identification of persons who are at risk and a thorough baseline nursing assessment with frequent ongoing assessments to monitor and detect changes in patients at risk. Frequent monitoring of all patients' vital signs is not necessary. Aseptic technique for all invasive procedures should always be implemented but will not prevent all types of shock. Health promotion activities that reduce the risk for precipitating conditions, such as coronary artery disease or anaphylaxis, may help to prevent shock in some cases.

When administering any vasoactive drug during the treatment of shock, the nurse should know that what is the goal of the therapy? a. Increasing urine output to 50 mL/hr b. Constriction of vessels to maintain BP c. Maintaining a MAP of at least 60 mm Hg d. Dilating vessels to improve tissue perfusion

c. Vasoactive drugs are those that can either dilate or constrict blood vessels and are used in various stages of shock treatment. When using either vasodilators or vasoconstrictors, it is important to maintain a mean arterial pressure (MAP) of at least 60 mm Hg so that adequate perfusion is maintained. The other goals would be appropriate only with either vasodilators or vasoconstrictors, not with all vasoactive drugs.

a nurse is caring for a client who has a prescription for an afterload reducing medication. the nurse should identify that this medication is administered for which of the following types of shock cardiogenic hypovolemic obstructive distributive

When assessing a patient in shock, the nurse recognizes that the hemodynamics of shock include? a)Normal cardiac output and normal blood pressure. b)Increase in central venous pressure in hypovolemic shock. c)Increase in systemic vascular resistance in septic shock d)Variations in cardiac output and decreased systemic vascular resistance in septic shock.

d)variation in cardiac output and decreased systemic vascular resistance in septic shock

What is the key factor in describing any type of shock? a. Hypoxemia b. Hypotension c. Vascular collapse d. Inadequate tissue perfusion

d. Although all of the factors may be present, regardless of the cause, the end result is inadequate supply of oxygen and nutrients to body cells from inadequate tissue perfusion.

As the body continues to try to compensate for hypovolemic shock, there is increased angiotensin II from the activation of the renin-angiotensin-aldosterone system. What physiologic change occurs related to the increased angiotensin II? a. Vasodilation b. Decreased blood pressure (BP) and CO c. Aldosterone release results in sodium and water excretion d. Antidiuretic hormone (ADH) release increases water reabsorpton

d. Angiotensin II vasoconstricts both arteries and veins, which increases blood pressure (BP). It stimulates aldosterone release from the adrenal cortex, which results in sodium and water reabsorption and potassium excretion by the kidneys. The increased sodium raises serum osmolality and stimulates the pituitary gland to release antidiuretic hormone (ADH), which increases water reabsorption, which further increases blood volume, leading to an increase in BP and CO.

During administration of IV norepinephrine (Levophed), what should the nurse assess the patient for? a. Hypotension b. Marked diuresis c. Metabolic alkalosis d. Decreased tissue perfusion

d. As a vasopressor, norepinephrine may cause severe vasoconstriction, which would further decrease tissue perfusion, especially if fluid replacement is inadequate. Vasopressors generally cause hypertension, reflex bradycardia, and decreased urine output because of decreased renal blood flow. They do not directly affect acid-base balance.

Progressive tissue hypoxia leading to anaerobic metabolism and metabolic acidosis is characteristic of the progressive stage of shock. What changes in the heart contribute to this increasing tissue hypoxia? a. Arterial constriction causes decreased perfusion. b. Vasoconstriction decreases blood flow to pulmonary capillaries. c. Increased capillary permeability and profound vasoconstriction cause increased hydrostatic pressure. d. Decreased perfusion occurs, leading to dysrhythmias, decreased CO, and decreased oxygen delivery to cells.

d. Decreased myocardial perfusion leads to dysrhythmias and myocardial ischemia, further decreasing CO and oxygen delivery to cells. The kidney's renin-angiotensin- aldosterone system activation causes arteriolar constriction that decreases perfusion. In the lung, vasoconstriction of arterioles decreases blood flow and a ventilation-perfusion mismatch occurs. Areas of the lung that are oxygenated are not perfused because of the decreased blood flow, resulting in hypoxemia and decreased oxygen for cells. Increased capillary permeability and vasoconstriction cause increased hydrostatic pressure that contributes to the fluid shifting to interstitial spaces.

Priority Decision: A patient with acute pancreatitis is experiencing hypovolemic shock. Which initial orders for the patient will the nurse implement first? a. Start 1000 mL of normal saline at 500 mL/hr. b. Obtain blood cultures before starting IV antibiotics. c. Draw blood for hematology and coagulation factors. d. Administer high-flow oxygen (100%) with a non-rebreather mask.

d. In every type of shock there is a deficiency of oxygen to the cells and high-flow oxygen therapy is indicated. Fluids would be started next, blood cultures would be done before any antibiotic therapy, and laboratory specimens then could be drawn

In late irreversible shock in a patient with massive thermal burns, what should the nurse expect the patient's laboratory results to reveal? a. Respiratory alkalosis b. Decreased potassium c. Increased blood glucose d. Increased ammonia (NH3) levels

d. In late irreversible shock, progressive cellular destruction causes changes in laboratory findings that indicate organ damage. Increasing ammonia levels indicate impaired liver function. Metabolic acidosis is usually severe as cells continue anaerobic metabolism and the respiratory alkalosis that may occur in the compensatory stage has failed to compensate for the acidosis. Potassium levels increase and blood glucose decreases.
