Burn Final Exam Questions

1). Burn injuries typically result from energy transfer from various heat sources to the body. These sources include:

  1. Chemical and electrical
  2. Thermal, electrical and chemical
  3. Electrical, thermal, chemical and cold exposure
  4. Chemical, electrical, thermal and ionizing radiation

Answer: D

Rationale: A burn injury usually results from energy transfer from a heat source to the body. The heat source may be thermal, chemical, or electrical. Exposure to ionizing radiation can also cause burns.

2). High- voltage electric entry wound are _________ in appearance, whereas exit wounds are more likely to _________ as the charge exits.

  1. Black; Turn red
  2. Charred and leathery; “blow out”
  3. Necrotic; appear edematous
  4. Bright red and weeping; appear charred and leathery

Answer: B

Rationale: High-voltage current is concentrated at its entrance to the body, then diverges centrally, and finally converges before exiting. The most severe damage to tissue occurs at the sites of contact and exit.

3). A patient who presents with a third degree burn covering the anterior trunk and both right upper and lower extremities would be said to have what percentage of total body surface area burned?

  1. 50%
  2. 35%
  3. 45%
  4. 62%

Answer: C

Rationale: According to the Rule of Nines, the anterior trunk equates to 18%, each leg 18%, and each arm 9%. See page 443 in the text for more information.

4). Which is an example of a moderate or uncomplicated burn injury?

  1. Second-degree burns less than 15% total-body surface area in adults
  2. Third-degree burns less than 10% total-body surface area not involving special care areas
  3. All burns involving eyes, ears, face, hands, feet, perineum and joints
  4. Third-degree burns of less than 2% total-body surface area in children

Answer: B

Rationale: See chart within the text on page 444

5) The nurse knows that the leading cause of death within the first 24 hours after a burn injury is:

  1. infection
  2. inhalation injury
  3. trauma
  4. hypovolemia

Answer: B

Rationale: see page 444 under Inhalation Injury.

6). Which method is the most accurate way to assess whether a patient with carbon monoxide toxicity is responding to oxygen therapy?

  1. ABGs
  2. Pulse oximetry
  3. Just pH
  4. End-tidal carbon monoxide monitoring

Answer: A

Rationale: see page 446 under carbon monoxide toxicity. Pulse oximetry is unable to distinguish oxygen from carbon monoxide in hemoglobin.

7) A patient was severely burned in a house fire 6 days ago. The nurse suspects that the patient has an infection after discovering which assessment finding:

  1. An elevated core temperature
  2. Bronchopneumonia
  3. An elevated white blood cell count
  4. glucosuria

Answer: D.

Rationale: see page 446. Diagnosing infection in a burn patient is difficult because most of these patients already have an elevated core body temperature and white blood cell count. Therefore, glucose in the urine is a much better sign of infection in a burn patient, especially in the presence of a normal blood glucose level.


8). A patient arrives at the emergency department with an electrical burn. The nurse conducts the the secondary assessment. What questions should the nurse ask in determining the possible severity of the burn injury? Select all that apply.

  1. Where was the patient when the burn occurred?
  2. How long was the patient in contact with the current?
  3. How much voltage was involved?
  4. What was the point of contact with the current?
  5. All of the above

Answer: B, C

9). A nurse sees a teenager get struck by lightning during a thunderstorm on a golf course. What should be the FIRST action by the nurse?

  1. Get to teenager side as soon as possible because his injuries may be serious and life threatening.
  2. Call for help and assess the environmental for hazards first
  3. Immediately conduct the ABCDE survey
  4. First move the patient out of danger to a dry place.
  5. Avoid the situation because someone else will take care of it.

Answer: B


10). A 70-year-old patient has experienced a sunburn over much of the body. What self-care treatment measure is MOST important to emphasize to an older adult in dealing with the effects of the sunburn?

  1. increasing fluid intake
  2. applying mild lotions  
  3. taking mild analgesics
  4. maintaining warmth
  5. using sunscreen

Answer: A


11).  A patient receiving treatment for severe burns over more than half of his body has an indwelling urinary catheter. When evaluating the patient's intake and output, which of the following should be taken into consideration?

  1. The amount of urine will be reduced in the first 24-48 hours, and will then increase.
  2. The amount of urine output will be greatest in the first 24 hours after the burn injury.
  3. The amount of urine will be reduced during the first eight hours of the burn injury and will then increase as the diuresis begins.
  4. The amount of urine will be elevated due to the amount of intravenous fluids administered during the initial phases of treatment.
  5. The amount of urine is expected to be decreased for three to five days.

Answer: A


12). When evaluating the laboratory values of the burn-injured patient, which of the following can be anticipated?

  1. decreased hemoglobin and elevated hematocrit levels
  2. elevated hemoglobin and elevated hematocrit levels
  3. elevated hemoglobin and decreased hematocrit levels
  4. decreased hemoglobin and decreased hematocrit levels
  5. hemoglobin and hematocrit levels within normal ranges

Answer: A

Endocrine Questions

1) In a critically ill patient, what would be the preferred method of blood glucose measurement?

a) venous line

b) arterial line

c) central line

d) all of the above

Rationale: The preferred method of blood glucose measurement in the critically ill patient is through venous lines, central lines or arterial lines over fingerstick glucose testing because often times tissue perfusion is impaired in the critically ill.

 

2) Jerry is a 17 year old male who has been diagnosed with DKA. Which lab values would you expect the nurse to monitor? (select all that apply)

a) urine ketones

b) serum ketones

c) glucagon

d) ADH

Rationale: Urine ketones are positive in DKA. Serum ketones and glucagon are elevated in DKA. ADH is monitored in patients who have SIADH or DI.

a) “I have a hemoglobin A1C of 11 so I won’t be needing any treatment for diabetes”

b) “The hemoglobin A1C gives a good idea of what my blood sugars have been over the past three to four months”

c) “My A1C level will tell me what my blood sugars have been for the last couple of days”

d) “My hemoglobin A1C is 5% which means I will need to start treatment for diabetes”

Rationale: A patient with a hemoglobin A1C level of above 7% should begin treatment. The hemoglobin A1C measures blood glucose levels over three to four months (the life span of a red blood cell is 100-120 days).

4. A 23 year old female with type 1 diabetes mellitus came into the emergency room after becoming increasingly ill. The nurse suspects DKA  and knows that this diabetic emergency is precipitated by which of the following: (select all that apply)

  1. UTI
  2. compliance with oral medications
  3. alcohol and drug abuse
  4. discontinuation of insulin therapy

Rationale: infection, usually UTI and pneumonia, is the most common precipitating factor of DKA. THe infection provokes the release of counterregulatory hormones that cause hyperglycemia. Other precipitating factors can include stroke, MI, pancreatitis, alcohol or drug abuse, trauma, or a discontinuation of of insulin therapy.

5. DKA is characterized by which of the following signs/symptoms: (select all that apply)

  1. polyuria
  2. hypovolemia signs
  3. hyperosmolality
  4. “fruity” breath
  5. hypoglycemia

Rationale: hypoglycemia can be a result of increased insulin administration, skipped meals, or excessive exercise. DKA has hyperglycemia as a result of low or no insulin.

6. A patient is being started on an insulin infusion. Prior to beginning this infusion, which should the nurse assess first?

  1. potassium level
  2. sodium level
  3. glucose level
  4. GFR

Rationale: potassium levels should be assessed prior to insulin therapy because insulin will push potassium back into the cell, lowering serum potassium.

7. A patient in DKA is on an insulin infusion. Which of the following should be done when the patient’s blood glucose level has reached 250 mg/dl?

  1. continue insulin infusion
  2. provide IV fluids with 0.9% NS
  3. provide IV fluids with 5% dextrose
  4. monitor BS every 2 hours

Rationale: D5W is added to prevent a precipitous decline in the blood glucose level.

8. A nineteen year old female comes into the ED with a blood glucose reading of 49 mg/dL. She is alert and oriented and responds to all of your questions. What should you expect from the physician?

  1. 1 mg glucagon SQ
  2. 25 grams of 50% dextrose bolus
  3. orange juice with 15 grams of carbs
  4. glucose tablet with 30 grams of carbs

Rationale: For a conscious adult liquid carbs PO is the best and quickest method of absorption. 15 grams of carbs will raise blood glucose 20-120mg/dL; so start with 15 grams and then recheck glucose levels in 15 minutes.

9. A  diabetic patient is admitted with CKD. Upon discharge you chose to provide some education regarding management of the disease. Which topics should you cover? Select all that apply.

  1. a high protein diet
  2. managing glucose levels
  3. information on ACE inhibitors
  4. a low sodium diet
  5. a high potassium diet

Rationale: Goals of diabetic patients with CKD include managing HTN (ACE inhibitors), managing glucose levels to prevent further damage to kidneys, and a low sodium, low protein diet. High potassium diets should be avoided as damaged kidneys may already have difficulties managing electrolytes.

10. A diabetic patient is admitted  to your floor for acute renal failure. What lab results is the most important to monitor?

  1. potassium levels
  2. chloride levels
  3. pH levels
  4. hematocrit

Rationale: In acute renal failure the biggest complications are fluid and electrolyte imbalances. The most important to monitor for is potassium as high levels of potassium can lead to cardiac arrhythmias.

Respiratory Questions

  1. Which of the following physical assessment findings are normal for a client with advanced COPD?
  1. Increased anteroposterior chest diameter.
  2. Underdeveloped neck muscles.
  3. Collapsed neck veins.
  4. Increased chest excursions.

    Answer: A; Rationale: Increased anteroposterior chest diameter is characteristic of COPD. Air is trapped in the overextended alveoli, which puts the ribs in a fixed inspiratory position. The result is a barrel chest appearance. B is not the answer because neck muscles become overdeveloped due to their increased use to aid in breathing. C is not the answer because veins become distended in COPD as a symptom of heart failure secondary to the increased workload on the heart to pump blood into the pulmonary vasculature. D is not the answer because decreased chest excursions are associated with COPD.
  1. Which of the following diets would be most appropriate for a client with COPD?
  1. Low-fat, low-cholesterol diet.
  2. Band, soft diet.
  3. Low-sodium diet.
  4. High-calorie, high-protein diet.

    Answer: D: A high-calorie, high protein diet helps the client maintain nutritional status and prevents weight loss that is a result of increased work of breathing. The client is encourage to eat small, frequent meals throughout the day. A is not the answer because a low-fat, low-cholesterol diet is indicated for clients with CAD. B is not the answer because there is no need for a soft-bland diet. C is not the answer because clients with COPD usually don’t require sodium restriction unless indicated.
  1. The nurse reviews an ABG report for a client with COPD. The results are: pH 7.35; PCO2 62; PO2 70; HCO3 34. The nurse should first:
  1. Apply a 100% non-rebreather mask.
  2. Assess the vital signs.
  3. Reposition the client.
  4. Prepare for intubation.

Answer: B: Clients with COPD retain CO2 and the respiratory drive is stimulated when PO2 decreases. Thus, HR, RR, and BP should be evaluated to determine if the client is hemodynamically stable. Symptoms such as dyspnea should also be assessed. A is not the correct answer because oxygen should be titrated up slowly. D is not the correct answer because the patient is not exhibiting signs of respiratory distress requiring intubation.

  1. An oxygen delivery system is prescribed for a male client with chronic obstructive pulmonary disease to deliver a precise oxygen concentration. Which of the following types of oxygen delivery systems would the nurse anticipate to be prescribed?
  1. face tent
  2. venturi mask
  3. aerosol mask
  4. tracheostomy collar

        Answer: B. Rationale: The Venturi mask delivers the most accurate oxygen concentration. It is the best oxygen delivery system for the client with chronic airflow limitation because it delivers a precise oxygen concentration. The face tent, aerosol mask, and tracheostomy collar are also high-flow oxygen delivery systems but most often are used to administer high humidity.

5. A male client admitted to an acute care facility with pneumonia is receiving supplemental oxygen, 2 L/minute via nasal cannula. The client’s history includes chronic obstructive pulmonary disease (COPD) and coronary artery disease. Because of these history findings, the nurse closely monitors the oxygen flow and the client’s respiratory status. Which complication may arise if the client receives a high oxygen concentration?

  1. apnea
  2. anginal pain
  3. respiratory acidosis
  4. metabolic alkalosis

Answer: A. Rationale: Hypoxia is the main breathing stimulus for a client with COPD. Excessive oxygen administration may lead to apnea by removing that stimulus. Anginal pain results from a reduced myocardial oxygen supply. A client with COPD may have anginal pain from generalized vasoconstriction secondary to hypoxia; however, administering oxygen at any concentration dilates blood vessels, easing anginal pain. Respiratory alkalosis results from alveolar hyperventilation, not excessive oxygen administration. In a client with COPD, high oxygen concentrations decrease the ventilatory drive, leading to respiratory acidosis, not alkalosis. High oxygen concentrations don’t cause metabolic acidosis.

6. For a patient with advanced chronic obstructive pulmonary disease (COPD), which nursing action best promotes adequate gas exchange?

  1. Encouraging the patient to drink three glasses of fluid daily
  2. Keeping the patient in semi-fowler’s position
  3. Using a high-flow venturi mask to deliver oxygen as prescribed
  4. Administering a sedative, as prescribed

Answer: C. Rationale: The patient with COPD retains carbon dioxide, which inhibits stimulation of breathing by the medullary center in the brain. As a result, low oxygen levels in the blood stimulate respiration, and administering unspecified, unmonitored amounts of oxygen may depress ventilation. To promote adequate gas exchange, the nurse should use a Venturi mask to deliver a specified, controlled amount of oxygen consistently and accurately. Drinking three glasses of fluid daily would not affect gas exchange or be sufficient to liquefy secretions, which are common in COPD. Patients with COPD and respiratory distress should be places in high-Fowler’s position and should not receive sedatives or other drugs that may further depress the respiratory center.

7. Which of the following are significant data to gather from a client who has been diagnosed with pneumonia? Select all that apply.

  1. Quality of breath sounds
  2. Presence of bowel sounds
  3. Occurrence of chest pain
  4. Amount of peripheral edema
  5. Color of nail beds

Answer: A, C, E; Rationale: A respiratory assessment, which includes auscultating breath sounds and assessing the color of nail beds, is a priority for clients with pneumonia. Assessing for the presence of chest pain is also an important respiratory assessment as chest pain can interfere with the client’s ability to breathe deeply. Auscultating bowel sounds and assessing for peripheral edema may be appropriate assessments, but these are not priority assessments for the client with pneumonia.

8. Which of the following assessments is most appropriate for determining the correct placement of an endotracheal tube in a mechanically ventilated client?

  1. Assessing the client’s skin color
  2. Monitoring the respiratory rate
  3. Verifying the amount of cuff inflation
  4. Auscultating breath sounds bilaterally

    Answer: D; Auscultation of bilateral breath sounds is the most appropriate method for determining cuff placement. The nurse should also look for the symmetrical rise and fall of the chest and should note the location of the exit mark on the tube. Assessments of skin color, respiratory rate, and the amount of cuff inflation cannot validate the placement of the endotracheal tube.

9. Which of the following complications is associated with mechanical ventilation?

  1. Gastrointestinal hemorrhage
  2. Immunosuppression
  3. Increased cardiac output
  4. Pulmonary emboli

    Answer: A; Gastrointestinal hemorrhage occurs in about 25% of clients receiving prolonged mechanical ventilation because of the development of stress ulcers. Clients who are receiving steroid therapy and those with a previous history of ulcers are most likely to be at risk. Other possible complications include incorrect ventilation, oxygen toxicity, fluid imbalance, decreased cardiac output, pneumothorax, infection and atelactasis.

10. A client has the following arterial blood gas values: pH, 7.52; PaO2: 50 mm Hg, PaCO2: 22 mm Hg; HCO3: 24 mEq/L. The nurse determines that which of the following is a possible cause for these findings?
        a. Chronic Obstructive Respiratory Disease (COPD)

b. Diabetic Ketoacidosis with Kussmaul’s respirations

c. Myocardial infarction

d. Pulmonary embolus

Answer: D; A PaCO2 of 28 mm Hg and PaO2 of 50 mm Hg are both abnormal; the PaO2 of 50 mm Hg signifies acute respiratory failure. In evaluating possible causes for this disorder, the nurse should consider conditions that lead to hypoxia and hyperventilation, such as pulmonary embolus. COPD is typically associated with respiratory acidosis and elevated PaCO2. The client with diabetic ketoacidosis most often has metabolic acidosis. A myocardial infarction does not often cause an acid-base imbalance because the primary problem is cardiac in origin.

Cardiovascular Final Exam Questions

1. An older adult client has chest pain and shortness of breath. The healthcare provider prescribes nitroglycerin tablets. What should the nurse instruct the client to do?

A. Put the tablet under the tongue until it is absorbed.

B. Swallow the tablet with 120ml of water.

C. Chew the tablet until it is dissolved.

D. Place the tablet between the cheek and gums until it disappears.

Answer: A

The client is having symptoms of a myocardial infarction. The first action is to prevent platelet formation and block prostaglandin synthesis. The client should place the tablet under the tongue and wait until it is absorbed Nitroglycerin tablets are not effective if chewed, swallowed, or placed between the cheek and gums.

2. A 60-year-old comes into the emergency department with crushing substernal chest pain that radiates to the shoulder and left arm. The admitting diagnosis is acute myocardial infarction (MI). Admission prescriptions include oxygen by nasal cannula at 4L/min, complete blood count (CBC), a chest radiograph, a 12-lead electrocardiogram (ECG), and 2mg of morphine sulfate given IV. The nurse should first:

A. Administer the morphine.

B. Obtain a 12-lead ECG.

C. Obtain the blood work.

D. Prescribe the chest radiograph.

Answer: A

Although obtaining the ECG, chest radiograph, and blood work are all important, the nurse's priority action should be to relieve the crushing chest pain. Therefore, administering morphine sulfate is the priority action.

3. Which of the following is the most appropriate diet for a client during the acute phase of myocardial infarction?

A. Liquids as desired.

B. Small, easily digested meals.

C. Three regular meals per day.

D. Nothing by mouth.

Answer: B

Recommended dietary principles in the acute phase of MI include avoiding large meals because small, easily digested foods are better tolerated. Fluids are given according to the client's needs, and sodium restrictions may be prescribed, especially for clients with manifestations of heart failure. Cholesterol restrictions may be prescribed as well. Clients are not prescribed diets of liquids only or restricted to nothing by mouth unless their condition is very unstable.

4. A client has chest pain rated at 8 on a 10-point visual analog scale. The 12-lead electrocardiogram reveals ST elevation in the inferior leads and troponin levels are elevated. What is the highest priority for nursing management of this client at this time?

  1. Monitor daily weights and urine output.
  2. Permit unrestricted visitation by family and friends.
  3. Provide client education on medications and diet.
  4. Reduce pain and myocardial oxygen demand.

Answer: D

Nursing management for a client with a MI should focus on pain management and decreasing myocardial oxygen demand. Fluid status should be closely monitored. Client education should begin once the client is stable and amenable to teaching. Visitation should be based on client comfort and maintaining a calm environment.

5. The client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA) to treat angina. Priority goals for the client immediately after PTCA should include:

  1. Minimizing dyspnea.
  2. Maintaining adequate blood pressure control.
  3. Decreasing myocardial contractility.
  4. Preventing fluid volume deficit.

Answer: D

Because the contrast medium used in PTCA acts as an osmotic diuretic, the client may experience diuresis with resultant fluid volume deficit after the procedure. Additionally, potassium levels must be closely monitored because the client may develop hypokalemia due to diuresis. Dyspnea would not be anticipated after this procedure. Maintaining adequate blood pressure control should not be a problem after the procedure. Increased myocardial contractility would be a goal, not decreased contractility.

6. A client has a history of heart failure and has been taking furosemide (Lasix), digoxin (Lanoxin), and potassium chloride. The client has nausea, blurred vision, headache, and weakness. The nurse notes that the client is confused. The telemetry strip shows first-degree atrioventricular block. The nurse should assess the client for signs of which of the following?

  1. Hyperkalemia.
  2. Digoxin toxicity.
  3. Fluid deficit.
  4. Pulmonary edema.

Answer: B

Early symptoms of digoxin toxicity include anorexia, nausea, and vomiting. Visual disturbances can also occur, including double or blurred vision and visual halos. Hypokalemia is a common cause of digoxin toxicity associated with arrhythmias because low serum potassium can enhance ectopic pacemaker activity. Although vomiting can lead to fluid deficit, given the client’s history, the vomiting is likely due to the adverse effects of digoxin toxicity. Pulmonary edema is manifested by dyspnea and coughing.

7. Most patients who present with Hypertensive Crisis are very ill and require immediate attention. The most appropriate intervention is administering IV medication to lower blood pressure keeping in consideration that the goal is to:

  1. Reduce the mean blood pressure by no more than 35% within one hour of starting treatment.
  2. Reduce the mean blood pressure by no more than 25% within one hour of starting treatment.
  3. Reduce the mean blood pressure by no more than 35% within two hours of starting treatment.
  4. Reduce the mean blood pressure by no more than 25% within two hours of starting treatment.

 

Answer: B

The goal is to reduce the mean blood pressure by no more than 25% within one hour of starting treatment to avoid hypoperfusion and to prevent or reverse target organ damage.

 

8. Which of the following IV medications are not used in the treatment of Hypertensive Emergencies?

  1. Nitroprusside Sodium.
  2. Esmolol.
  3. Nitroglycerin.
  4. Norepinephrine.

 

Answer: D

Norepinephrine stimulates alpha receptors to cause peripheral vasoconstriction and systemic vascular resistance increasing blood pressure.

 

9. The most important long term goal for a client with hypertension is to:

  1. Learn how to avoid stress.
  2. Explore a job change or early retirement.
  3. Make a commitment to long term therapy.
  4. Lose weight.

 

Answer: C

Compliance is the most important element of hypertension. In most cases, hypertension requires long term therapy which include medications.

10. A client is scheduled for cardiac catheterization. The nurse should do which of the following pre-procedure tasks? Select all that apply.

  1. Administer all prescribed oral medications.
  2. Check for iodine sensitivity.
  3. Verify that written consent has been obtained.
  4. Withhold food and oral fluids before the procedure.
  5. Insert a urinary catheter.

Answer: B, C, D

For clients scheduled for a cardiac catheterization it is important to assess for iodine sensitivity, verify written consent, and instruct the client to take nothing by mouth for 6 to 18 hours before the procedure. Oral medications are withheld unless specifically prescribed. A urinary drainage catheter is rarely required for this procedure.

Hemodynamics

 Question 1:

 

 The phlebostatic axis is located at the:

A. Fourth-intercostal space, midaxillary level

B.Sixth-intercostal space, anterior level

C.Second-intercostal space, midaxillary level

D.Third-intercostal space, midaxillary level

Answer: A- Leveling the transducer at the phlebostatic axis is necessary for accurate A-line waveforms and readings. 

Question 2:

 

A nurse notices that his/her patient’s continuous pressure device has deflated to less than 300 mmHg. The nurse should expect to see what type of waveforms:

A.Optimally damped

B.Overdamped

C.Underdamped

D.No alterations in the waveforms

Answer: B

Question 3:

The purpose of arterial lines is to (select all that apply):

A.Obtain frequent arterial blood gases

B.Infuse medications

C.Monitor CVP

D.Monitor blood pressure continuously

Answer: D- Arterial lines are used to monitor blood pressure continuously and accurately. Blood can also be drawn from this line, but frequent ABGs would not be appropriate without a rationale.  Medications are not to be administered through this line, and CVP is not recorded.

Question 4:  

A client has a systemic arterial blood pressure monitor. Which of the following should be included in the plan of care for this client?

A.Administer fluids through this access device

B.Monitor the site for infection

C.If tubing becomes kinked, take a routine BP using cuff method

D.Monitor circulation proximal to the insertion site

Answer: B

Question 5:

The nurse knows that pulmonary artery pressure monitoring measures the pressures in the: (select all that apply)

A.Right atrium

B.Left atrium

C.Right ventricle

D.Pulmonary artery

E.Femoral artery

Answers: A, C, D

Question 6:

 The nurse has just measured a client’s cardiac output using the thermodilution method. The findings show a notched, uneven curve.

What should the nurse do with these results?

A.Document the finding as a high cardiac output

B.Document the finding as a low cardiac output

C.Repeat the measurement

D.Nothing. There is nothing wrong with the reading

Answer: C: Repeat the measure. A small curve indicates a high CO, a large curve indicates a low CO, and a notched or uneven curves indicates poor injection technique and the assessment should be repeated.

Question 7:

 To demonstrate an understanding of the concept of afterload, the nurse identifies which of the following patients as having increased afterload?

A.A hypothermic post-op coronary artery bypass surgical patient

B.A post-op carotid endarterectomy patient on nitroprusside

C.A patient presenting in the early stages of septic shock

D.A patient with chest pain who is receiving IV nitroglycerin

Answer: A- Hypothermia causes vasoconstriction, which leads to increased afterload. B,C, and D are all patient scenarios in which the patient is experiencing vasodilation, which leads to decreased afterload

Question 8:

 The critical care nurse is concerned about increased oxygen demand for which of the following patients? (select all that apply)

A.Critically ill post-op patient who is shivering

B.Patient who has indications of developing septic shock

C.Patient who had percutaneous transluminal coronary angioplasty

D.Newly admitted multiple trauma patient

Answer: A, B, D- All these patients have conditions in which the body is consuming oxygen at a higher than normal rate.

Shock and MODS

  1. Your 83-year old male patient with a diagnosis of myocardial infarction has gone into cardiogenic shock. He has a history of diabetes mellitus, hypercholesterolemia, and DVT. Which of these factors are associated with the development of cardiogenic shock? Select all that apply.
  1. Advanced age
  2. Hypercholesterolemia
  3. DVT
  4. Diabetes mellitus
  5. Gender

2) A patient who has recovered from cardiogenic shock asks how this condition develops. The nurse’s best response includes that cardiogenic shock develops:

  1. As a result of inadequate blood volume
  2. As a result of the heart’s inability to contract adequately
  3. As a result of vasodilation that decreases blood return to the heart
  4. As a result of an overwhelming infection

3) You have just conducted an initial assessment of a patient transferred to the ICU after the development of cardiogenic shock. Which of the following is not an expected sign of this condition?

  1. Systolic blood pressure of 67 mm Hg
  2. Respiratory rate of 26 breaths per minute
  3. Pulmonary artery occlusion pressure (PAOP) of 23 mm Hg
  4. Warm, dry skin
