What action would be most helpful to the nurse in determining whether the chest pain of a patient who has just entered the emergency department is cardiac in origin? 1. Gathering a complete medical history 2. Performing a 12-lead ECG 3. Administering NTG to see if the pain goes away 4. Asking the patient if performing a Valsalva maneuver reduces the pain

ANS: 2 A 12-lead ECG is performed immediately if the symptoms are suggestive of pain that is cardiac in origin.

A patient is very short of breath. Which finding should cause the nurse to be concerned that the shortness of breath might be due to heart failure? 1. An echocardiogram that reflected increased right ventricular wall thickening 2. A B-type natriuretic peptide (BNP) of 300 pg/mL 3. A left ventricular ejection fraction (VEF) of 50% 4. A serum sodium of 135

ANS: 2 A BNP greater than 100 pg/mL suggests heart failure as a cause of dyspnea.

Which nursing actions would be appropriate when a nurse is initiating an infusion of morphine sulfate for a post-operative patient who is experiencing pain? 1. Anticipate that the patient will begin to experience the effect of the morphine 15 minutes after the start of the infusion. 2. Provide additional intermittent boluses of morphine sulfate if the patient experiences breakthrough pain. 3. Complete the Critical-Care Pain Observation Tool scale 5 minutes after increasing the infusion rate each time. 4. Begin the infusion at the lowest ordered dose and increase the rate every 30 minutes if the patient continues to have pain.

ANS: 2 A critically ill patient often will receive an IV bolus of an analgesic followed by an ongoing infusion of the pain medication with intermittent boluses and increases in infusion until the drug attains steady state and the patient experiences pain relief.

Members of the multidisciplinary care team are reviewing a patient's nutritional status and analyzing assessment values. Which value would need additional investigation? 1. A serum albumin of more than 3.5 g/dL or 35 g/L 2. A weight increase of 1.5 kg in a day 3. A serum hemoglobin of 11.7 g/dL or 117 mmol/L 4. A prealbumin level of 35 mg/dL

ANS: 2 A weight change of 1.5 kg (approximately 3.3 lb) reflects approximately 1.5 liters of fluid. Additional assessment needs to be done to evaluate the cause and risks.

Which patient would the nurse identify as experiencing a critical illness? The patient: 1. With chronic airflow limitation whose VS are BP 110/72, P 110, R 16 2. With acute bronchospasm and whose VS are BP 100/60, P 124, R 32 3. Who was involved in a motor vehicle crash whose VS are BP 124/74, P 74, R 18 4. On hemodialysis for chronic renal failure with no urine output and whose VS are BP 98/50, P 108, R 12

ANS: 2 Acute bronchospasm can present a life-threatening situation, which can jeopardize a patient's survival. The patient's pulse and respiratory rate are elevated, which could indicate a critical illness.

A patient says, "I've never heard of an acute coronary syndrome. Please explain what happened to me." The nurse should respond, "Acute coronary syndrome is: 1. Another name for a myocardial infarction (MI) or heart attack." 2. A group of disorders that result in insufficient oxygen supply to the heart." 3. The second leading cause of death in the United States." 4. A type of abnormal heart rhythm."

ANS: 2 Acute coronary syndrome (ACS) is an inclusive term for conditions that cause chest pain due to insufficient blood supply to the heart muscle.

A patient with heart failure has a decreasing cardiac output. The nurse will expect compensatory mechanisms to be activated in order to: 1. Decrease the heart rate 2. Maintain perfusion to vital organs 3. Cause arteriolar vasodilation in nonessential vascular beds 4. Inhibit the release of aldosterone

ANS: 2 As the heart function fails and cardiac output decreases, compensatory mechanisms are activated to maintain perfusion to the vital organs.

What will the nurse do when administering antibiotics to a patient with sepsis? 1. Antibiotics should be administered as soon as the patient has received a fluid bolus. 2. Antibiotics should always be administered after blood cultures are obtained. 3. Administer the antibiotic with the shortest administration time first so that all antibiotics are administered quickly. 4. Wait for the results of liver and renal function tests before beginning antibiotic therapy.

ANS: 2 Blood cultures must be obtained prior to the administration of antibiotics in order to isolate the infecting organism successfully.

A patient tells a nurse, "My chest pain starts when I am resting, and when I had a cardiac catheterization, the doctor said I was having vasospasms." Which type of medication would the nurse anticipate to be prescribed to treat the patient's angina? 1. A vasodilator such as nitroglycerin (NTG) 2. A calcium channel blocking agent 3. An antidysrhythmic such as lidocaine 4. A beta adrenergic blocking agent

ANS: 2 Calcium channel blocking agents would be the drug of choice to stop the spasms of the coronary arteries that are causing the hypoxic pain in the myocardium from Prinzmetal's angina

Which statement best describes the pathophysiology of multiple organ dysfunction syndrome (MODS) in a patient with sepsis? 1. The primary cause of MODS is decreased blood pressure. 2. Endothelial dysfunction is a primary cause of MODS. 3. Increased microvascular bleeding causes MODS. 4. Circulating pathogens cause destruction of organs, resulting in MODS.

ANS: 2 Endothelial dysfunction is a primary cause of MODS.

A physician suggests that a ventilated patient needing immediate transport to CT scan and having severe pain be given IV fentanyl (Sublimaze) rather than morphine sulfate for pain management. One reason the physician might recommend the use of fentanyl (Sublimaze) is: 1. Rapid administration does not have any hemodynamic consequences. 2. It has a more rapid onset and a shorter duration of action. 3. Weaning of a continuous infusion is never needed due to its short half-life. 4. It is not likely to cause respiratory depression.

ANS: 2 Fentanyl is 100 times more potent than morphine. It has a faster onset of action than morphine and a shorter duration of action.

What would the nurse not expect to find in a patient who was experiencing acute decompensated heart failure with pulmonary edema? 1. Dyspnea at rest, peripheral edema 2. Hypertension, bradycardia 3. Increased coughing, crackles 4. Decreased O2 saturation, increased PAWP

ANS: 2 Hypertension and bradycardia are not symptoms of pulmonary edema.

The nurse should warm intravenous fluids when a rapid infuser is being utilized to prevent which complication? 1. Hemorrhagic shock 2. Hypothermia 3. Sepsis 4. Cardiogenic shock

ANS: 2 Hypothermia can result when providing room temperature fluids at a faster pace than the body can warm them.

A nurse is caring for a ventilated post-operative patient who might be experiencing pain. Which method of assessing the patient's pain level should the nurse try first? 1. Attempting an analgesic trial 2. Asking the patient if he is in pain 3. Observing the patient's face for grimacing 4. Asking a family member if the patient is in pain

ANS: 2 If the patient is responsive, the nurse should ask the patient about presence of pain.

A patient is demonstrating pulmonary edema, hypotension, and delayed capillary refill. The nurse suspects the patient is experiencing which type of shock? 1. Hypovolemic 2. Cardiogenic 3. Anaphylactic 4. Obstructive

ANS: 2 In cardiogenic shock, there is a low cardiac output, hypotension, and pulmonary edema.

For a nurse to be found guilty of negligence, it must be demonstrated that the patient: 1. Was assaulted 2. Incurred damages 3. Suffered a wrongful death 4. Was not consulted before being touched

ANS: 2 In order to prove negligence, damages must have occurred to the patient.

Which finding indicates that a patient is experiencing increased peripheral resistance and vasoconstriction? 1. Strong bounding pulse with deep red coloring 2. Pale, cool extremities with decreased pulses 3. Increased venous engorgement with strong pulses 4. Faster than normal capillary refill time

ANS: 2 Increased peripheral resistance causes the blood supply to decrease and results in decreased blood to the tissues, which causes pallor and decreased skin temperatures. The pulses would decrease in intensity with a decreased blood supply.

Which laboratory finding should cause the nurse to suspect that a patient is developing hypovolemic shock? 1. Serum sodium of 130 mEq/L (130 mmol/L) 2. Metabolic acidosis validated by arterial blood gases 3. Serum lactate of 3 mmol/L 4. SvO2 greater than 80%

ANS: 2 Metabolic acidosis is present due to an accumulation of carbonic acid, leaving a bicarbonate deficit from decreased tissue perfusion.

Which evidence based intervention would the nurse use to prevent pneumonia in the patient receiving mechanical ventilation? 1. Aseptic technique when performing oral hygiene 2. Administration of an H2 antagonist to prevent peptic ulcers 3. Elevation of the head of the bed to 15 degrees to prevent aspiration 4. Changing the ventilator circuit daily

ANS: 2 One of the evidence based practices used to prevent ventilator-associated pneumonia includes the use of an H2 antagonist to prevent peptic ulcers.

A patient in heart failure is to be started on an infusion of dobutamine (Dobutrex). What is most important for the nurse to assess before starting the infusion? The patient's: 1. Breath sounds 2. Blood pressure 3. Level of consciousness 4. Urine output

ANS: 2 Prior to initiation, before each titration, and at the peak action of dobutamine, the nurse must assess blood pressure, heart rate, respiratory rate, and oxygen saturation. Frequent assessment of these parameters should continue throughout the infusion period.

What would be included in the collaborative management of a patient's pulmonary status following coronary artery bypass graft surgery? 1. Keeping the patient intubated for at least 48 hours to maximize gas exchange 2. Mobilizing the patient as soon as possible to prevent atelectasis and venous stasis 3. Evaluating readiness for extubation based on guidelines: PO2 less than 80 mm Hg with an FiO2 greater than 40% and a PCO2 greater than 45 4. Extubating when the patient is arousable to noxious stimuli and shows increased effort for spontaneous breathing

ANS: 2 Pulmonary functions decline with immobility. Gravitational pull on secretions to posterior areas and inadequate inflation cause atelectasis. Activity and position changes will increase mobility of secretions. Even if the patient is intubated, extra movement by changing of positions will minimize respiratory complications or congestion in the lungs, both of which will increase the work effort of the heart and decrease perfusion and ventilation if not corrected.

Which communication strategy is most appropriate for a critical care nurse to use when communicating with a ventilated patient? The nurse should: 1. Use professional terminology and provide the patient with detailed information. 2. Use simple language and explain in other terms if the patient does not seem to understand. 3. Provide minimal information so the patient is not overwhelmed. 4. Discuss issues primarily with the family because the patient is unlikely to understand the information.

ANS: 2 Simple layman's language of information is better understood and repeating or rephrasing gives the patient a better understanding when in a stressful situation.

The nurse, providing care to patients in a critical care unit, realizes that technology increases the likelihood of errors when: 1. It relies heavily on human decision making. 2. Devices are programmed to function without double checks. 3. It makes the workload seem overwhelming to health care providers. 4. There is uniform equipment throughout each facility.

ANS: 2 Technology changes the tasks people do by shifting the workload and eliminating human decision making.

What will the nurse include in the management plan for a patient with sepsis? 1. Use high tidal volumes on the ventilator to prevent adult respiratory distress syndrome (ARDS). 2. Assess capillary blood glucose and prevent hyperglycemia. 3. Stabilize and debride an infected wound after administering antibiotics for 24 hours. 4. Avoid CT and MRI scans until the patient is stable.

ANS: 2 The blood glucose should be maintained between 80 and 150 mg/dL.

The nurse identifies a patient in the critical care unit as having "resiliency." What characteristic has the nurse identified in the patient? 1. Motivation to reduce anxiety through positive self-talk 2. Ability to bounce back quickly after an insult 3. Physical strength to endure extreme physical stressors 4. Ability to return to a state of equilibrium

ANS: 2 The correct definition of "resiliency" is the ability to bounce back quickly after an insult. The degree of resiliency is placed along a continuum between being unable to mount a response to having strong reserves.

The nurse is evaluating a patient for the presence of systemic inflammatory response syndrome (SIRS). Which assessment data indicates the presence of SIRS? 1. Temperature 36.4°C, respiratory rate 22, pulse rate 112, and PaCO2 34 2. Temperature 38.4°C, respiratory rate 23, pulse rate 92, and PaCO2 31 3. Temperature 37.2°C, respiratory rate 24, pulse rate 102, and PaCO2 44 4. Temperature 38.8°C, respiratory rate 25, pulse rate 88, and PaCO2 48

ANS: 2 The definition of SIRS includes temperature 38 degrees centigrade, pulse greater than 90 beats per minute, respiratory rate greater than 20 breaths per minute with a PaCO2 less than 32 torr.

A nurse is administering haldoperidol (Haldol) via IV push to a delirious patient. What is most important for the nurse to monitor in this patient? 1. Heart rate 2. QT interval 3. PR interval 4. Respiratory rate

ANS: 2 The patient needs to be monitored for such adverse effects as QT prolongation and dysrhythmias (torsades de pointes), which can result in sudden death, especially if the drug is administered via IV push.

Which solution would be the most appropriate initial volume replacement for a patient with severe GI bleeding? 1. 200 mL of normal saline (NS) per hour for 5 hours 2. A liter of Ringer's lactate (RL) over 15 minutes 3. Two liters of D5W over half an hour 4. 500 mL of 0.45% normal saline (1/2 NS) over half an hour

ANS: 2 The patient requires immediate infusion of an adequate amount of fluid. Fluid resuscitation begins with 500 to 1,000 mL of an isotonic solution.

A patient with heart failure begins to cough pink frothy sputum. Which pressure would the nurse assess to confirm this manifestation? 1. Central venous pressure 2. Pulmonary capillary wedge pressure 3. Arterial pressure 4. Right arterial pressure

ANS: 2 The pulmonary capillary wedge pressure would be elevated in pulmonary edema. This is the pressure that the nurse would assess to confirm the patient's symptom.

The nurse, implementing the sepsis management bundle for a patient in the intensive care unit, is aware of which information about this bundle? 1. When all elements of the sepsis management bundle are used, survival is prolonged. 2. The sepsis management bundle has not received uniform support. 3. The purpose of the sepsis management bundle is to improve the patient's hemodynamics within 4 hours. 4. The Surviving Sepsis Campaign recommends universal use of each of the elements of the sepsis management bundle to decrease mortality.

ANS: 2 The sepsis management bundle has not received uniform support because the elements have not been shown to increase survival or to decrease mortality.

Steroids may be prescribed to a patient in septic shock. For what additional interventions would the nurse plan when providing this medication? 1. There is a slower reversal of sepsis when steroids are given. 2. There is a risk of superinfection when steroids are given. 3. Vasopressor therapy can often be reduced when steroids are given. 4. Immunosuppression is reduced when steroids are given.

ANS: 2 The use of steroids in the treatment of sepsis can lead to more problems with superinfection.

The nurse realizes that the increased use of technology in critical care units has resulted in which consequence for patient care? 1. Decreased risk of errors in patient care 2. Decreased therapeutic nurse-patient communication 3. Improved overall patient satisfaction with care 4. Improved patient safety across the entire spectrum

ANS: 2 This has been demonstrated as an outcome resulting from an increased use of technology in critical care units.

Which statement describing the needs of family members of critically ill patients has not been validated by research? 1. "Not knowing is the worst part" of waiting. 2. Families in the waiting room have no effect on patient outcomes. 3. "Hovering" in the proximity phase is characterized by confusion and tension. 4. A unified message from staff minimizes family stressors.

ANS: 2 This is an incorrect statement that is not supported by research. In fact the family support has been proven to clinical outcomes.

Which finding would support the diagnosis of heart failure (HF)? 1. RA/CVP of 8 mm Hg 2. PAWP of 20 mm Hg 3. Cardiac index of 3 4. Peripheral vasodilation reflected by normalizing capillary refill times

ANS: 2 With heart failure the backup of fluid from inadequate pumping results in increased PAWP because the heart has to pump harder to push through the rising capillary pressures on the venous side from peripheral edema and ascites.

Which life-threatening complications would the nurse anticipate developing in the patient being treated for hypovolemic shock? Standard Text: Select all that apply. 1. Fluid volume overload 2. Renal insufficiency 3. Cerebral ischemia 4. Gastric stress ulcer 5. Pulmonary edema

ANS: 2, 3 Rationale 2: Renal insufficiency is a serious complication because of the prerenal etiology of hypovolemia. Rationale 3: Early identification and correction of the fluid volume deficit in hypovolemic shock is necessary to prevent cerebral ischemia.

What will the nurse identify as symptoms of hypovolemic shock in a patient? Standard Text: Select all that apply. 1. Temperature of 97.6°F (36.4°C) 2. Restlessness 3. Decrease in blood pressure of 20 mm Hg when the patient sits up 4. Capillary refill time greater than 3 seconds 5. Sinus bradycardia of 55 beats per minute

ANS: 2, 3, 4 Rationale 2: Due to decreased blood flow to the brain and peripheral areas when blood is shunted to maintain the vital organs, cerebral hypoxia occurs, leading to a change in mental status. Rationale 3: Orthostatic hypotension is a manifestation of hypovolemic shock. Rationale 4: Due to decreased blood flow to the brain and peripheral areas when blood is shunted to maintain the vital organs, capillary refill time will be reduced.

To increase compliance and reduce postoperative complications, the nurse should include which topics in the preoperative teaching for a patient who is to have a coronary artery bypass graft (CABG)? Standard Text: Select all that apply. 1. Reasons for cooling blankets in post-op period 2. Equipment used: IVs, Foley, pacer wires, chest tubes, NG tubes, ECG leads 3. Alternate methods for communicating when intubated 4. Reasons and techniques of turning, coughing, and deep breathing once extubated 5. Drug management: need for sedation when intubated, pain med through PCA

ANS: 2, 3, 4, 5 This should be included in the teaching.

Which findings would cause the nurse to suspect that a post-coronary artery bypass patient might be developing cardiac tamponade? Standard Text: Select all that apply. 1. Widening pulse pressure 2. Increased jugular vein distension 3. Decreasing central venous pressure (CVP) 4. Muffled heart sounds 5. Lack of pleural (chest) tube drainage

ANS: 2, 4, 5 Rationale 2: As the heart is compressed within its own pericardial sac from fluid accumulation, the ability to expand is limited because fluid accumulates outside the heart to the point in which contraction cannot occur. The pressures back up and create increased pressure as seen with engorging jugular veins. Rationale 4: As the heart is compressed within its own pericardial sac from fluid accumulation, the ability to expand is limited because fluid accumulates outside the heart to the point in which contraction cannot occur. The fluid surrounding the heart muffles the heart sounds. Rationale 5: Fluid ceases to drain from the pericardial tubes into the pleural (chest) tubes. As the heart is compressed within its own pericardial sac from fluid accumulation, the ability to expand is limited because fluid accumulates outside the heart to the point in which contraction cannot occur

A patient in heart failure is being given a first dose of lisinopril (Prinivil) 10 mg PO. Which finding would cause the nurse to question the administration of the first dose? 1. Heart rate 92 beats per minute 2. Blood pressure 100/72 3. Potassium 5.7 mEq/dL 4. Urine output 35 mL/hr

ANS: 3 Ace inhibitors increase the serum potassium and a further increase from 5.7 could be problematic so the nurse should question the administration of this medication.

Which assessment finding indicates that a patient's heart failure (HF) is worsening? 1. An increase in O2 saturation to greater than 90% 2. A decrease in heart rate to 66 bpm 3. The onset of atrial fibrillation 4. Louder S1 and S2 heart sounds

ANS: 3 As heart failure continues to progress, less oxygenation occurs all over the body, especially the myocardium, which is sensitive to the hypoxia and will result in dysrhythmias such as ventricular ectopy or atrial fibrillation.

The nurse in the critical care area is completing a preoperative checklist before sending a patient for surgery. This nurse's activity is an example of which recommendation issued by the Institute of Medicine? 1. Utilizing constraints 2. Simplifying key processes 3. Avoiding reliance on vigilance 4. Standardizing key processes

ANS: 3 Completing a preoperative checklist is an example of avoiding reliance on vigilance.

An 80-year-old woman has arrived in the emergency department. The health care provider is questioning whether she has had an MI although she is not displaying the classic chest pain. Which symptoms would more likely occur in this patient than others because of the patient's gender and age? 1. Jaw and/or tooth pain 2. Centralized chest pain 3. Generalized fatigue accompanied by dyspnea and diaphoresis 4. Dyspnea accompanied by crackles in all lobes

ANS: 3 Coronary symptoms in women include fatigue, diaphoresis, and nonspecific pain that is different than that identified by men.

The nurse, caring for a patient in hypovolemic shock, will not utilize a hypotonic solution for fluid resuscitation because hypotonic solutions: 1. Move quickly into the interstitial spaces and can cause third spacing 2. Stay longer to expand the intravascular space but deplete intracellular fluid levels 3. Do not stay in the intravascular space long enough to expand the circulating blood volume 4. Need a smaller bore needle to run at a slower rate to keep the intravascular space low

ANS: 3 Hypotonic solutions do not stay in the intravascular space long enough to expand the circulating blood volume.

Which statement will the nurse use to explain why serum lactate is elevated in a patient with sepsis? It is caused by: 1. Increased systemic inflammation 2. The endogenous by-products of bacterial contamination 3. Anaerobic cellular metabolism 4. Greatly accelerated coagulation

ANS: 3 Lactic acid is produced as a by-product of anaerobic cellular metabolism.

The nurse, employed in a hospital in a small rural town, would expect to provide which level of care in the critical care unit? 1. Level I 2. Level II 3. Level III 4. It is unlikely that the hospital would have a critical care unit.

ANS: 3 Level III facilities provide initial stabilization of critically ill patients but limited ability to provide comprehensive critical care. A limited number of patients who require routine care may remain in the facility but written policies should be in place determining which patients require transfer and where they ought to be transferred. This level of care is most likely provided in a small rural facility.

Which statement accurately describes the purpose of sedation vacation for a patient to prevent ventilator-associated pneumonia? 1. The vacation from sedation relieves stress, which decreases the chance of infection. 2. During sedation vacation the patient has a chance to take deep breaths and improve ventilation while more awake. 3. The patient's own tidal volume and respiratory rate can be evaluated during sedation vacation. 4. New data show that sedation vacation is no longer recommended because there is concern about the safety of interrupting sedation.

ANS: 3 Mechanical ventilation is discontinued sooner when close attention is given to measuring tidal volume and respiratory rate, which occurs during a sedation vacation. Evidence indicates that appropriate use of daily interruption of sedation to determine readiness to wean decreases the patient's time on a ventilator.

Which laboratory value would the nurse review to validate a diagnosis of a myocardial infarction (MI) that was suspected of occurring approximately 3 hours earlier? 1. CK 2. Troponin T assay 3. Myoglobin 4. PTT

ANS: 3 Myoglobin will peak between 1 and 4 hours after the hypoxic/necrotic event and return to normal in 24 hours. Therefore, it is the first to rise when tissue damage has occurred.

Which hemodynamic parameters would the nurse expect to see in the patient with septic shock? 1. Central venous pressure (CVP) 4 mm Hg, pulmonary artery pressure (PAP) 30/15 mm Hg, and systemic vascular resistance (SVR) 1,200 dynes/sec/cm-5 2. Central venous pressure (CVP) 8 mm Hg, pulmonary artery pressure (PAP) 26/10 mm Hg, and systemic vascular resistance (SVR) 1,000 dynes/sec/cm-5 3. Central venous pressure (CVP) 2 mm Hg, pulmonary artery pressure (PAP) 20/8 mm Hg, and systemic vascular resistance (SVR) 800 dynes/sec/cm-5 4. Central venous pressure (CVP) 6 mm Hg, pulmonary artery pressure (PAP) 40/20 mm Hg, and systemic vascular resistance (SVR) 700 dynes/sec/cm-5

ANS: 3 Septic shock is a form of distributive shock. Central venous pressure would be low, pulmonary artery pressure would be low, and systemic vascular resistance would be low.

During an assessment, a ventilated patient begins to frown and wiggle about in bed. Which assessment strategy would be most helpful for the nurse to validate these observations? 1. Glasgow Scale 2. Maslow's hierarchy levels 3. Critical-Care Pain Observation Tool (CPOT) 4. Vital signs trends

ANS: 3 The CPOT pain scale will identify if pain is present and the degree of effectiveness of drug management in a patient who cannot speak due to intubation.

Why will the nurse monitor the SVO2 in a patient with septic shock? 1. A SvO2 of 65% shows that the oxygen demand of tissues exceeds the oxygen supply. 2. A SvO2 of 95% or above shows normal oxygen supply and demand. 3. A SvO2 of 70% is adequate to deliver oxygen to body organs and tissues. 4. A decrease in the SvO2 shows that more oxygen is returning to the lungs before being metabolized.

ANS: 3 The SvO2 is a measure of systemic oxygen utilization and an indirect measure of perfusion. The normal SvO2 is 60% to 80%. A SvO2 of 70% is normal, indicating adequate oxygen delivery to body organs and tissues.

The nurse is assessing a patient for severe sepsis. Which finding indicates the patient is developing this health problem? 1. Decreased capillary filling and mottling 2. Fever and decreased urine output 3. Hypotension and lactic acidosis 4. Increased glomerular filtration rate and increased D-dimer levels

ANS: 3 The best description of severe sepsis is hypotension and lactic acidosis. These signs also represent altered cellular metabolism, which results in organ dysfunction.

The best description of the overall goal of providing fluid resuscitation and vasopressors to a patient in septic shock is to: 1. Increase the systolic arterial pressure. 2. Provide adequate vasoconstriction. 3. Increase tissue perfusion. 4. Increase the metabolic rate.

ANS: 3 The overall goal of providing fluid resuscitation and vasopressors to the patient in septic shock is to increase tissue perfusion. Vasopressors are used if the initial fluid bolus fails to bring the mean arterial pressure over 80 mm Hg.

A patient is admitted with chest discomfort and a possible UA/NSTEMI. What would be a contraindication to administration of GP-IIb-IIIA inhibitors to the patient? The patient had: 1. Major surgery in the last 6 months 2. A creatinine level of 1.4 mg/dL 3. A stroke within the past month 4. A platelet count greater than 150,000 mm3

ANS: 3 The purpose of this drug is to prevent platelet aggregation by keeping fibrinogen from binding to the GP IIb-IIIA receptors on the platelet surfaces. This condition is a contraindication for giving this drug group because increased bleeding episodes might follow its administration.

The nurse working within the AACN Synergy Model realizes that optimal patient outcomes are realized when: 1. Highly qualified nurses care for patients in highly technical settings. 2. Nurses agree to work overtime to cover unit staffing needs. 3. Staff nurse competency is matched with patient needs. 4. Patient care is delivered within a "closed unit" model.

ANS: 3 The underlying assumption of the Synergy Model is that optimal patient outcomes occur when the needs of the patient and family are matched with the competencies of the nurse.

The nurse recognizes that which patient would be most likely to develop hypovolemic shock? A patient with: 1. Decreased cardiac output 2. Severe constipation, causing watery diarrhea 3. Ascites 4. Syndrome of inappropriate ADH (SIADH)

ANS: 3 Third spacing shifts move the fluids from the intravascular space into the interstitial space, causing a drop in the circulating blood volume. Therefore, third spacing is a risk factor for the development of hypovolemic shock.

When concluding SBAR communication about a patient issue, the nurse will use which statement? 1. "The patient's immediate history is..." 2. "The patient's physical findings are..." 3. "I am requesting that you..." 4. "I have assessed the patient personally."

ANS: 3 This statement would be used when concluding SBAR communication.

A nurse is confirming the medication orders and schedule for sedative administration to a patient with delirium. Which schedule would maximize the effectiveness of the drugs? Administration of medication: 1. Only in the early morning 2. Only at bedtime (HS) 3. Around the clock with higher dosages in the evening 4. Only on an as-needed (PRN) basis

ANS: 3 Timing medication given around the clock with a greater dosage in the evening will match the symptom of sundowning, when the symptoms appear the greatest later in the day.

The nurse is teaching a patient about acute coronary syndrome. What will the nurse teach that describes the progression of events in this disorder? 1. A thin fibrin layer stabilizes the ruptured plaque and prevents the occlusion of coronary vessels when stable angina is present in ACS. 2. When complete platelet occlusion occurs in a vessel, the ECG changes include nonspecific ST elevation without necrosis occurring in ACS. 3. The growth of platelet-rich thrombi in the smaller vessels creates a blockage and is the cause for unstable angina symptoms in ACS. 4. Sudden plaque buildup in a narrow vessel immediately leads to an acute myocardial infarction when stable angina is present in ACS.

ANS: 3 Unstable angina occurs when a blockage from platelet-rich thrombi in smaller vessels occurs, causing myocardial ischemia. Because ischemic pattern of pain varies, it is unpredictable and can occur with exertion and rest.

The nurse notes that the QRS duration of a patient with a biventricular pacemaker is widening? What does this most likely indicate? 1. Worsening of the patient's underlying cardiomyopathy 2. Loss of ventricular capture 3. Loss of ventricular synchronization 4. Battery failure

ANS: 3 Widening of the QRS duration from the baseline may indicate a loss of ventricular synchronization.

The nurse realizes that which stressor is one of the primary concerns of critically ill patients and should be routinely included during assessments? 1. Inability to control elimination 2. Lack of family support 3. Hunger 4. Altered ability to communicate

ANS: 4 Altered ability to communicate is identified as a primary concern of critically ill patients

The nurse is instructing a patient with a myocardial infarction about the disease process. Which patient statement indicates that additional teaching is needed? 1. "A heart attack is the same as a myocardial infarction (MI)." 2. "A heart attack causes tissue death and that part of the heart may not pump as well." 3. "A heart attack in the anterior wall of the heart can be very serious because a large portion of the heart may not pump as well." 4. "Angina always leads first to decreased blood flow to the heart muscle and then to tissue death."

ANS: 4 Angina pectoris is the pain from ischemia, but necrosis of myocardial tissue does not occur with each episode of pain. The pain is from tissue hypoxia; ischemia areas may improve or deteriorate into necrosis due to collateral circulation from other vessels.

The nurse is identifying interventions to prevent the development of sepsis in an older patient because: 1. Mortality rates from sepsis are 70% worldwide. 2. If managed early and aggressively, the majority of patients with sepsis may be managed outside of the ICU environment. 3. The guidelines provided by the Surviving Sepsis Campaign are expected to decrease the incidence of sepsis. 4. Sepsis rates rise sharply with age.

ANS: 4 Because sepsis affects the elderly disproportionately, more than half of all annual costs in the United States—$8.7 billion—were spent on care of septic patients 65 years or older.

A nurse is preparing to administer the first 5 mg dose of metoprolol (Toprol) to a patient who is 12 hours post MI. For which assessment finding should the nurse withhold administration of the medication? 1. Serum potassium 3.9 mEq/L 2. Blood pressure of 110/65 mm Hg 3. PR interval 0.12 second 4. Sinus bradycardia 52 beats per minute

ANS: 4 Beta blocker therapy is contraindicated when the patient has a heart rate less than 60 beats per minute, systolic blood pressure less than 100 mm Hg, moderate or severe left ventricular failure, shock, PR interval on the electrocardiogram greater than 0.24 second, second- and third-degree heart block, and active asthma and/or reactive airway disease.

After teaching a patient with heart failure about beta blocking agents, the nurse recognizes that additional teaching is needed when the patient states, "While taking the medication, I will: 1. Weigh myself every day." 2. Check my blood sugar regularly." 3. Notify my health care provider if I become increasingly short of breath." 4. Monitor myself daily for an increased heart rate and blood pressure."

ANS: 4 Beta blocking agents will decrease the heart rate and blood pressure. This statement indicates that additional teaching is needed.

A patient with neurogenic shock is demonstrating bradycardia. What action will the nurse take at this time? 1. Limit patient movement. 2. Prepare to administer crystalloids. 3. Administer phenylephrine as prescribed. 4. Administer atropine as prescribed.

ANS: 4 Bradycardia in neurogenic shock is corrected by the administration of atropine at the dose of 0.5 to 1.0 mg intravenous every 5 minutes to a total dose of 3 mg.

Which action is a part of the bundle of measures used to prevent nosocomial catheter-related infections? 1. Chlorhexidine is most effective when swabbed starting at the insertion site and moving outward in a circular motion. 2. It is recommended that transparent dressings be changed every 72 hours to prevent growth of bacteria on the skin. 3. Current recommendations support changing IV tubing every 48 hours on patients at risk for catheter-related infections. 4. During insertion of a central line the doctor should wear a cap and mask, sterile gloves, and a gown, and the patient should have a full body drape.

ANS: 4 During insertion of a central line the doctor should wear a cap, a mask, sterile gloves, and a gown. The patient should have a full body drape. These measures prevent catheter-related sepsis.

The electrocardiogram of a patient receiving tPA for a myocardial infarction shows that the ST segment has returned to baseline. How should the nurse interpret this finding? 1. The spasm in the coronary artery has resolved. 2. The myocardial injury is evolving. 3. The patient has become more relaxed. 4. The blocked artery has been reperfused.

ANS: 4 Early reperfusion can resolve coronary ischemia.

In order to meet the patient's nutritional needs during a critical illness with sepsis, the nurse knows that: 1. TPN is the preferable means to administer nutrition. 2. Nutritional needs are usually addressed after 72 hours in order to conserve energy expenditure. 3. Enteral feedings are often avoided because hyperglycemia often results from feedings. 4. Enteral feedings prevent translocation of bacteria from the gastrointestinal tract.

ANS: 4 Enteral feedings are the preferred method of meeting nutritional needs because they prevent translocation of bacteria from the gastrointestinal tract.

The nurse caring for a patient would ensure that the patient has consented to care by providing what to the patient? 1. A consent form to sign to receive medications 2. A consent form to sign to have dressings changed 3. A consent form to sign to be turned in bed 4. An explanation of a dressing to be changed

ANS: 4 If the nurse does not ask the patient for consent, the nurse should explain the procedure.

Which statement explaining the relationship of body weight to acute coronary syndrome (ACS) should the nurse include when presenting a healthy heart program to a community group? 1. Excessive weight will result in a decrease in low-density lipoproteins (LDL) that is linked to ACS. 2. Extra weight can lead to diabetes insipidus that will increase the risk for ACS. 3. Losing as little as 5% of one's body weight will significantly lower the risk for ACS. 4. Obesity, a BMI of greater than 30, increases the risk for ACS.

ANS: 4 Increased weight increases the risk for diabetes mellitus and decreased HDL, which are both risk factors for ACS.

A nurse is teaching a patient with coronary artery disease about prescribed nitroglycerin therapy. Which patient statement indicates further teaching is needed? 1. "If the pain doesn't go away I can take a second tablet after 5 minutes." 2. "I should not take nitroglycerin if I have taken Viagra." 3. "I should try to sit or lie down when I take the nitroglycerin." 4. "I'll put a couple of tablets in a plastic bag in my pocket so I have them with me all the time."

ANS: 4 Nitroglycerin should be kept in a tightly sealed brown bottle.

The goal of antibiotic therapy in a patient with sepsis is to narrow the therapy to one narrow-spectrum antibiotic. What purpose does this goal serve in the patient's care and how does it aid in the prevention of antibiotic resistance? 1. The use of one antibiotic ensures that the prescribed dose will result in serum concentrations that are clinically effective. 2. The use of one antibiotic has been shown to cause less organ dysfunction. 3. The use of one antibiotic reduces mortality in patients with sepsis. 4. The use of one antibiotic limits the cost to the patient.

ANS: 4 One antibiotic can ultimately reduce the patient's costs but that is not the only purpose of this goal.

"The chest pain occurs each time I play basketball; it does not occur when I am sleeping; and it improves when I take those pills under my tongue," the pain will most likely be classified as: 1. Variant or Prinzmetal's angina 2. Undifferentiated angina 3. Unstable angina 4. Stable angina

ANS: 4 Stable angina occurs in a predictable manner, not when resting, and improves with NTG under the tongue.

When teaching a patient with heart failure about ventricular remodeling, the nurse should recognize that additional teaching is needed if the patient makes which statement? "Remodeling: 1. Leads to progressive worsening of heart function." 2. Can be described as an enlargement of the pumping chamber." 3. Occurs with an increase in blood pressure and results in weight gain." 4. Develops primarily because the heart is pumping harder."When teaching a patient with heart failure about ventricular remodeling, the nurse should recognize that additional teaching is needed if the patient makes which statement? "Remodeling: 1. Leads to progressive worsening of heart function." 2. Can be described as an enlargement of the pumping chamber." 3. Occurs with an increase in blood pressure and results in weight gain." 4. Develops primarily because the heart is pumping harder."

ANS: 4 The heart is not pumping harder but rather the contractility or elasticity of the left ventricle is decreased or stiffer in nature. This statement indicates more teaching is required.

A patient starting cardiac rehabilitation will work with the rehabilitation team to meet all of the following goals except: 1. Taking control of his life through healthy choices 2. Managing symptoms by monitoring exercise 3. Reducing risks by controlling the modifiable risk factors 4. Stabilizing any severe depression that developed post-MI

ANS: 4 The need to stabilize emotions, such as depression and anxiety, are addressed but not a major psychiatric disorder, because it would require in-depth individualized counseling. A referral is needed because this is not the goal of the rehabilitation program.

The nurse is caring for a patient with acute decompensated heart failure (HF) receiving BiPAP. While caring for this patient, the nurse's priority will be to: 1. Monitor the expiratory time to be sure that it always exceeds the inspiratory time. 2. Ensure that the mask does not fit too tightly on the patient's face to prevent skin breakdown. 3. Prepare for endotracheal intubation because BiPAP is used primarily to buy time for intubation. 4. Assess the patient for the development of gastric distention, nausea, and vomiting.

ANS: 4 The nurse must assess the patient for complications resulting from this delivery method to include gastric distention, nausea, vomiting, and aspiration.

A nurse is caring for a patient who has just started to bleed from the insertion site following a cardiac catheterization. What should be the nurse's first response? The nurse should: 1. Administer vitamin K (AquaMEPHYTON). 2. Locate and apply a compression clamp. 3. Apply a collagen patch or sheath. 4. Apply manual pressure to the site.

ANS: 4 The nurse should immediately apply manual pressure to the site

Following angioplasty, a patient develops the following: hematuria, hypotension, tachycardia, a drop in hemoglobin and hematocrit, and a decrease in oxygen saturation. What is most likely the cause for these symptoms? 1. Reaction to vasovagal stimulation 2. Myocardial ischemia 3. Peripheral emboli distal to the insertion site 4. Over-anticoagulation

ANS: 4 The symptoms are a result of over-anticoagulation, which results in blood loss through the kidneys and other organs, resulting in a declining hemoglobin/hematocrit (H/H). The decrease of RBCs results in the compensation mechanism for shock by increasing the HR when compensating for the tissue hypoxia present from the lack of RBCs. Decreased perfusion and O2 saturation in the tissues will be present.

A ventilated patient is receiving midazolam (Versed) for sedation. The nurse would recognize that the patient is receiving an appropriate dose of midazolam when the patient is: 1. Awake with a respiratory rate of 38 and a heart rate of 132 2. Asleep but withdrawing to noxious stimuli with a heart rate of 80 3. Awake with a heart rate of 124 and attempting to pull out the IV 4. Asleep but awakening to light touch with a heart rate of 72

ANS: 4 These findings indicate appropriate sedation.

What will the nurse identify as an example of an installed forcing functions or a system level firewall to prevent errors when providing patient care? 1. Prior to administration of insulin, two nurses check the dose. 2. Prior to obtaining a medication, height, weight, and allergies are recorded. 3. All medications are checked by two nurses prior to administration. 4. Undiluted potassium chloride is not available on critical care units.

ANS: 4 This is an example of an installed forcing function or a system level firewall.

The nurse is addressing the family needs of a critically ill patient. Which family need was not identified? 1. Proximity 2. Information 3. Assurance 4. Timeliness

ANS: 4 Timeliness is not a need identified in Leske's research findings.

A patient is being discharged after an MI and is prescribed lisinopril (Prinivil) 10 mg daily. Which instruction is most appropriate for the nurse to give to the patient? 1. Avoid crossing your legs. 2. Weigh yourself at least 3 times a week. 3. Cut down on your sodium intake to 1,500 mg/day. 4. Change your position slowly when going from lying to sitting.

ANS: 4 Watching for postural hypotension when initiating therapy is important.

The nurse is aware that restraining a patient is most likely to result in the patient: 1. Pulling out an endotracheal tube 2. Pulling out an intravenous line 3. Disconnecting ventilator tubing 4. Developing a nosocomial infection

ANS: 4 When people are restrained, they are more likely to develop nosocomial infections.

If a nurse forcibly inserts a nasogastric tube against a patient's wishes, the nurse can be held liable for: 1. Negligence 2. Malpractice 3. Damages 4. Battery

ANS: 4 When the nurse treats or touches a patient without consent, it is battery.

A patient weighing 220 lbs is prescribed 10 mcg/kg/min of dopamine to improve cardiac output from cardiogenic shock. How many milligrams of dopamine will the patient receive in an hour?

ANS: 60 Determine the patient's weight in kg by dividing 220 lbs by 2.2 or 100 kg. Then multiply the number of mcg of medication the patient is to receive per minute by 100 kg or 10 mcg × 100 kg = 1,000 mcg. This is the dosage the patient will receive in 1 minute. To determine the amount of medication in 1 hour, multiply 1,000 mcg × 60 = 60,000 mcg. Using the conversion 1 mg = 1,000 mcg, divide 60,000 mcg by 1,000 mcg to determine that the patient will receive 60 mg of dopamine in 1 hour.
