The nurse is caring for a patient receiving intravenous ibuprofen for pain management. The nurse recognizes which laboratory assessment to be a possible side effect of the ibuprofen? a. Elevated creatinine b. Elevated platelet count c. Elevated white blood count d. Low liver enzymes
A Ibuprofen can result in renal insufficiency, which may be noted in an elevated serum creatinine level.
The rhythm on the cardiac monitor is showing numerous pacemaker spikes, but no P waves or QRS complexes following the spikes. The nurse realizes this as: a. normal pacemaker function. b. failure to capture. c. failure to pace. d. failure to sense.
B When the pacemaker generates an electrical impulse (pacer spike) and no depolarization is noted, it is described a failure to capture. On the ECG, a pacer spike is noted, but it is not followed by a P wave (atrial pacemaker) or a QRS complex (ventricular pacemaker). Common causes of failure to capture include output (milliamperes) set too low, or displacement of the pacing lead wire from the myocardium (transvenous or epicardial leads). Other causes of failure to capture include battery failure, fracture of the pacemaker wire, or increased pacing threshold as a result of medication or electrolyte imbalance. This is not normal pacemaker function.
The best way to monitor agitation and effectiveness of treating it in the critically ill patient is to use a/the: a. Confusion Assessment Method (CAM-ICU). b. FACES assessment tool. c. Glasgow Coma Scale. d. scale such as Richmond Agitation Sedation Scale.
D
The nurse is caring for a patient who requires administration of a neuromuscular blocking agent to facilitate ventilation with non-traditional modes. The nurse understands that neuromuscular blocking agents provide: a. antianxiety effects. b. complete analgesia. c. high levels of sedation. d. no sedation or analgesia.
D Neuromuscular blocking (NMB) agents do not possess any sedative or analgesic properties. Patients who receive NMBs must also receive a sedative agent.

A 65-year-old patient with a history of metastatic lung carcinoma has been unresponsive to chemotherapy. The medical team has determined that there are no additional treatments available that will prolong life or improve the quality of life in any meaningful way. Despite the poor prognosis, the patient continues to receive chemotherapy and full nutrition support. This is an example of what end-of-life concept? a. Medical futility b. Palliative care c. Terminal weaning d. Withdrawal of treatment
A Medical futility is a situation in which therapy or interventions will not provide a foreseeable possibility of improvement in the patient's health status.
Nociceptors differ from other nerve receptors in the body in that they: a. adapt very little to continual pain response. b. inhibit the infiltration of neutrophils and eosinophils. c. play no role in the inflammatory response. d. transmit only the thermal stimuli.
A Nociceptors are stimulated by mechanical, chemical, or thermal stimuli. Nociceptors differ from other nerve receptors in the body in that they adapt very little to the pain response.
The patient has a permanent pacemaker inserted. The provider has set the pacemaker to the demand mode at a rate of 60 beats per minute. The nurse realizes that: a. the pacemaker will pace only if the patient's intrinsic heart rate is less than 60 beats per minute. b. the demand mode often competes with the patient's own rhythm. c. the demand mode places the patient at risk for the R-on-T phenomenon. d. the fixed rate mode is safer and is the mode of choice.
A Pacemakers can be operated in a demand mode or a fixed rate (asynchronous) mode. The demand mode paces the heart when no intrinsic or native beat is sensed. For example, if the rate control is set at 60 beats per minute, the pacemaker will only pace if the patient's heart rate drops to less than 60. The fixed rate mode paces the heart at a set rate, independent of any activity the patient's heart generates. The fixed rate mode may compete with the patient's own rhythm and deliver an impulse on the T wave (R-on-T phenomenon), with the potential for producing ventricular tachycardia or fibrillation. The demand mode is safer and is the mode of choice.
Which of the following is true about a patient diagnosed with sinus arrhythmia? a. The heart rate varies, dependent on vagal tone and respiratory pattern. b. Immediate treatment is essential to prevent death. c. Sinus arrhythmia is not well tolerated by most patients. d. PR and QRS interval measurements are prolonged.
A Sinus arrhythmia is a cyclical change in heart rate that is associated with respiration. The heart rate increases slightly during inspiration and slows slightly during exhalation because of changes in vagal tone. The ECG tracing demonstrates an alternating pattern of faster and slower heart rate that changes with the respiratory cycle.
The patient has an irregular heart rhythm. To determine an accurate heart rate, the nurse first: a. identifies the markers on the ECG paper that indicate a 6-second strip. b. counts the number of large boxes between two consecutive P waves. c. counts the number of small boxes between two consecutive QRS complexes. d. divides the number of complexes in a 6-second strip by 10.
A Six-second method: A quick and easy estimate of heart rate can be accomplished by counting the number of P waves or QRS waves within a 6-second strip to obtain atrial and ventricular heart rates per minute. This is the optimal method for irregular rhythms. Identify the lines above the ECG paper that represent 6 seconds, and count the number of P waves within the lines; then add a zero (multiply by 10) to identify the atrial heart rate estimate for 1 minute. Next, identify the number of QRS waves in the 6-second strip and again add a zero to identify the ventricular rate.
The nurse is caring for a patient who is on a cardiac monitor. The nurse realizes that the sinus node is the pacemaker of the heart because it is: a. the fastest pacemaker cell in the heart. b. the only pacemaker cell in the heart. c. the only cell that does not affect the cardiac cycle. d. located in the left side of the heart.
A The cardiac cycle begins with an impulse that is generated from a small concentrated area of pacemaker cells high in the right atria called the sinoatrial node (sinus node or SA node). The SA node has the fastest rate of discharge and thus is the dominant pacemaker of the heart. The AV node has pacemaker properties and can discharge an impulse if the SA node fails. The ventricles have pacemaker capabilities if the sinus node or the AV node ceases to generate impulses.
The patient is receiving neuromuscular blockade. Which nursing assessment indicates a target level of paralysis? a. Glasgow Coma Scale score of 3 b. Train-of-four yields two twitches c. Bispectral index of 60 d. CAM-ICU positive
B A train-of-four response of two twitches using a peripheral nerve stimulator indicates adequate paralysis. The Glasgow Coma Scale does not assess paralysis; it is an indicator of consciousness. The Bispectral Index provides an assessment of sedation. The CAM-ICU is a tool to assess delirium
The nurse is assessing the patient's pain using the Critical Care Pain Observation Tool. Which of the following assessments would indicate the greatest likelihood of pain and need for nursing intervention? a. Absence of vocal sounds b. Fighting the ventilator c. Moving legs in bed d. Relaxed muscles in upper extremities
B Fighting the ventilator is rated with the greatest number of points for compliance with the ventilator, and could indicate pain or anxiety.
A patient who is undergoing withdrawal of mechanical ventilation appears anxious and agitated. The patient is on a continuous morphine infusion and has an additional order for lorazepam (Ativan) 1 to 2 mg IV as needed (prn). The patient has received no lorazepam (Ativan) during this course of illness. What is the most appropriate nursing intervention to control agitation? a. Administer fentanyl (Duragesic) 25 mg IV bolus. b. Administer lorazepam (Ativan) 1 mg IV now. c. Increase the rate of the morphine infusion by 50%. d. Request an order for a paralytic agent.
B Lorazepam (Ativan) 1 mg IV is an appropriate loading dose for a patient who is benzodiazepine naïve and experiencing agitation during withdrawal of life support. Fentanyl treats pain and morphine controls pain. Paralytic agents are not warranted.
The patient is admitted with a fever and rapid heart rate. The patient's temperature is 103° F (39.4° C).The nurse places the patient on a cardiac monitor and finds the patient's atrial and ventricular rates are above 105 beats per minute. P waves are clearly seen and appear normal in configuration. QRS complexes are normal in appearance and 0.08 seconds wide. The rhythm is regular, and blood pressure is normal. The nurse should focus on providing: a. medications to lower heart rate. b. treatment to lower temperature. c. treatment to lower cardiac output. d. treatment to reduce heart rate.
B Sinus tachycardia results when the SA node fires faster than 100 beats per minute. Sinus tachycardia is a normal response to stimulation of the sympathetic nervous system. Sinus tachycardia is also a normal finding in children younger than 6 years. Both atrial and ventricular rates are greater than 100 beats per minute, up to 160 beats per minute, but may be as high as 180 beats per minute. Sinus tachycardia is regular or essentially regular. PR interval is 0.12 to 0.20 seconds. QRS interval is 0.06 to 0.10 seconds. P and QRS waves are consistent in shape. P waves are small and rounded. A P wave precedes every QRS complex, which is then followed by a T wave.
The VALUE mnemonic is a helpful strategy to enhance communication with family members of critically ill patients. Which of the following statements describes a VALUE strategy? a. View the family as guests on the unit. b. Acknowledge family emotions. c. Learn as much as you can about family structure and function. d. Use a trained interpreter if the family does not speak English. e. Evaluate each encounter with the family.
B The VALUE mnemonic includes the following: V—Value what the family tells you. A—Acknowledge family emotions. L—Listen to the family members. U—Understand the patient as a person. E—Elicit (ask) questions of family members.
The nurse is calculating the rate for a regular rhythm. There are 20 small boxes between each P wave and 20 small boxes between each R wave. What is the ventricular rate? a. 50 beats/min b. 75 beats/min c. 85 beats/min d. 100 beats/min
B The rule of 1500 is used to calculate the exact rate of a regular rhythm. The number of small boxes between the highest points of two consecutive R waves is counted, and that number of small boxes is divided into 1500 to determine the ventricular rate. 1500/20 = 75 beats/min. This method is accurate only if the rhythm is regular
The patient is asymptomatic but is diagnosed with second-degree heart block Mobitz I. The patient is on digitalis medication at home. The nurse should expect that: a. the patient has had an anterior wall myocardial infarction. b. the physician will order the digitalis to be continued in the hospital. c. a digitalis level would be ordered upon admission. d. the patient will require a transcutaneous pacemaker.
C Digitalis toxicity is a major cause of this rhythm, and further digitalis doses should not be given until a digitalis level is obtained. Other causes of Mobitz I include AV nodal blocking drugs, acute inferior wall myocardial infarction or right ventricular infarction, ischemic heart disease, and excess vagal response. This type of block is usually well tolerated and no treatment is indicated unless the dropped beats occur frequently.
The nurse notices that the patient has a first-degree AV block. Everything else about the rhythm is normal. The nurse should: a. prepare to place the patient on a transcutaneous pacemaker. b. give the patient atropine to shorten the PR interval. c. monitor the rhythm and patient's condition. d. give the patient an antiarrhythmic medication.
C First-degree AV block is a common dysrhythmia in the elderly and in patients with cardiac disease. As the normal conduction pathway ages or becomes diseased, impulse conduction becomes slower than normal. It is well tolerated. No treatment is required. Continue to monitor the patient and the rhythm.
The nurse understands that in a third-degree AV block: a. every P wave is conducted to the ventricles. b. some P waves are conducted to the ventricles. c. none of the P waves are conducted to the ventricles. d. the PR interval is prolonged.
C In first-degree AV block, a P wave precedes every QRS complex, which is followed by a T wave indicating complete conduction. It is represented on the ECG as a prolonged PR interval. Second-degree heart block refers to AV conduction that is intermittently blocked. Therefore, some P waves are conducted and some are not. Third-degree block is often called complete heart block because no atrial impulses are conducted through the AV node to the ventricles.
Which statement made by a staff nurse identifying guidelines for palliative care would need corrected? a. Basic nursing care is a critical element in palliative care management. b. Common conditions that require palliative management are nausea, agitation, and sleep disturbance. c. Palliative care practices are reserved for the dying client. d. Palliative care practices relieve symptoms that negatively affect the quality of life of a patient.
C The purpose of palliative care is to relieve negative symptoms that affect the quality of life of a patient. Palliative care is an integral part of every injured or ill patient's care. Basic nursing care, including repositioning, skin care, and provision of a peaceful environment, promote comfort. These conditions all commonly require palliative care techniques.
The wife of a patient who is hospitalized in the critical care unit following resuscitation for a sudden cardiac arrest at work demands to meet with the nursing manager. She states, "I want you to reassign my husband to another nurse. His current nurse is not in the room enough to make sure he is okay." The nurse recognizes that this response most likely is due to the wife's: a. desire to pursue a lawsuit if the assignment is not changed. b. inability to participate in the husband's care. c. lack of prior experience in a critical care setting. d. sense of loss of control of the situation.
D Demanding behaviors often occur when the family member has a sense of loss of control or has had adverse outcomes in a previous hospitalization. Prevention of a lawsuit is not relevant to this scenario. No information is provided regarding whether the family member is participating in care or not. It is not known if she had a prior negative experience or not.
The patient's heart rate is 165 beats per minute. His cardiac monitor shows a rapid rate with narrow QRS complexes. The P waves cannot be seen, but the rhythm is regular. The patient's blood pressure has dropped from 124/62 to 78/30. His skin is cold and diaphoretic and he is complaining of nausea. The nurse prepares the patient for: a. administration of beta-blockers. b. administration of atropine. c. transcutaneous pacemaker insertion. d. emergent cardioversion.
D If an abnormal P wave cannot be visualized on the ECG but the QRS complex is narrow, the term supraventricular tachycardia (SVT) is often used. This is a generic term that describes any tachycardia that is not ventricular in origin; it is also used when the source above the ventricles cannot be identified, usually because the rate is too fast. Treatment is directed at assessing the patient's tolerance of the tachycardia. If the rate is higher than 150 beats per minute and the patient is symptomatic, emergent cardioversion is considered. Cardioversion is the delivery of a synchronized electrical shock to the heart by an external defibrillator.
A 45-year-old male postsurgical patient is on a ventilator in the critical care unit. He has been tolerating the ventilator well and has not required any sedation. He becomes tachycardic and hypertensive. His respiratory rate has increased to 28 breaths/min. The ventilator is set on synchronized intermittent mandatory ventilation (SIMV) at a rate of 10 breaths/min. The patient has been suctioned recently via his endotracheal tube, and his airway is clear. He responds appropriately to the nurse's commands. The nurse should: a. assess the patient's level of pain. b. decrease the SIMV rate on the ventilator. c. provide sedation as ordered. d. suction the patient again.

Each procedure should be evaluated for its effect on the patient's comfort before being implemented. c. Only the patient can determine what constitutes comfort care for him or her. d. Withdrawing life-sustaining treatments is considered euthanasia in most states.
b
The nurse is examining the patient's cardiac rhythm strip in lead II and notices that all of the P waves are upright and look the same except one that has a different shape and is inverted. The nurse realizes that the P wave with the abnormal shape is probably: a. from the SA node since all P waves come from the SA node. b. from some area in the atria other than the SA node. c. indicative of ventricular depolarization. d. normal even though it is inverted in lead II.
b Normally a P wave indicates that the SA node initiated the impulse that depolarized the atrium. However, a change in the shape of the P wave may indicate that the impulse arose from a site in the atria other than the SA node. The P wave represents atrial depolarization. It is usually upright in leads I and II and has a rounded, symmetrical shape. The amplitude of the P wave is measured at the center of the waveform and normally does not exceed three boxes, or 3 millimeters, in height.
The patient's heart rate is 70 beats per minute, but the P waves come after the QRS complex. The nurse correctly determines that the patient's heart rhythm is: a. a normal junctional rhythm. b. an accelerated junctional rhythm. c. a junctional tachycardia. d. atrial fibrillation.
b The normal intrinsic rate for the AV node and junctional tissue is 40 to 60 beats per minute, but rates can accelerate. An accelerated junctional rhythm has a rate between 60 and 100 beats per minute, and the rate for junctional tachycardia is greater than 100 beats per minute.
