Chapter 26: Management of Patients with Dysrhythmias and Conduction Problems
The nurse is educating the client about a transvenous pacemaker. What is the best statement to explain why the client will have a transvenous pacemaker?
"A transvenous pacemaker is used to manage transient bradydysrhythmias like those that occur during acute MIs." Explanation: A transvenous pacemaker is a temporary pulse-generating device that sometimes is necessary to manage transient bradydysrhythmias such as those that occur during acute MIs or after coronary artery bypass graft surgery, or to override tachydysrhythmias. The transvenous pacemaker is a temporary pacemaker introduced into the venous system, not the arterial system. The pacemaker does not manage ventricular dysrhythmias.
The nurse is caring for a 32-year-old client admitted with a medical diagnosis of atrial fibrillation, related to "holiday heart" syndrome. A nursing student working with the nurse asks for information about "holiday heart" syndrome. Which is the best response by the nurse?
"This is the association of heart dysrhythmias, especially atrial fibrillation, with binge drinking." Explanation: Atrial fibrillation may be found in people with acute moderate to heavy ingestion of alcohol.
Two nursing students are reading EKG strips. One of the students asks the instructor what the P-R interval represents. The correct response should be which of the following?
"It shows the time needed for the SA node impulse to depolarize the atria and travel through the AV node." Explanation: The PR interval is measured from the beginning of the P wave to the beginning of the QRS complex and represents the time needed for sinus node stimulation, atrial depolarization, and conduction through the AV node before ventricular depolarization. In a normal heart the impulses do not travel backward. The PR interval does not include the time it take to travel through the Purkinje fibers.
The nurse receives a telephone call from a client with an implanted pacemaker who reports a pulse of 68 beats per minute, but the pacemaker rate is set at 72 beats per minute. What is the nurse's best response?
"Please come to the clinic right away so that we may interrogate the pacemaker to see if it is malfunctioning." Explanation: A client experiencing pacemaker malfunctioning may develop bradycardia as well as signs and symptoms of decreased cardiac output. The client should check the pulse daily and report immediately any sudden slowing or increasing of the pulse rate, which may indicate pacemaker malfunction. The client needs to be evaluated to avoid cardiac output problems. Walking will not keep the heart rate at a safe level.
A client is unconscious on arrival to the emergency department. The nurse in the emergency department identifies that the client has a permanent pacemaker due to which characteristic?
"Spike" on the rhythm strip Explanation: Confirmation that the client has a permanent pacemaker is the characteristic "spike" identified by a thin, straight stroke on the rhythm strip. The scar on the chest is suggestive of pacer implantation but not definitive. There should be no change in pulse quality, and no vibration under the skin.
The nursing student asks the nurse to describe the difference between sinus rhythm and sinus bradycardia on the electrocardiogram strip. What is the nurse's best reply?
"The only difference is the heart rate." Explanation: All characteristics of sinus bradycardia are the same as those of normal sinus rhythm except for the rate, which will be below 60 in sinus bradycardia. The P waves will be shaped differently in other dysrhythmias. The QRS is the same voltage for sinus rhythms. The P-R interval is prolonged in atrioventricular blocks.
A client with a second-degree atrioventricular heart block, Type II is admitted to the coronary care unit. How will the nurse explain the need to monitor the client's electrocardiogram (ECG) strip to the spouse?
"The small box will transmit the heart rhythm to the central monitor all the time." Explanation: In telemetry, a small box transmits the client's heart rhythm to the central unit for constant monitoring. Telemetry has nothing to do with the client needing help. A Holter monitor is a device that records the heart's electrical activity and for later review by a physician. The telemetry transmits the heart rhythm regardless of the client's heart rate.
Which dysrhythmia is common in older clients?
Sinus bradycardia Explanation: Sinus bradycardia and atrial fibrillation are common dysrhythmia'a in older clients. Sinus tachycardia, sinus arrhythmmai, and ventricular tachycardia are not common dysrhythmias in older clients.
The nurse cares for a 56-year-old client who received an implantable cardioverter defibrillator (ICD) 2 days prior. The client tells the nurse "My wife and I can never have sex again now that I have this ICD." What is the nurse best response by the nurse?
"You seem apprehensive about resuming sexual activity." Explanation: The client treated with an electronic device experiences not only lifestyle and physical changes but also emotional changes. At different times during the healing process, the client may feel angry, depressed, fearful, anxious, or a combination of these emotions. It is imperative for the nurse to observe the client's response to the device and provide the client and family members with emotional support and teaching as indicated. Identifying that the client appears apprehensive about resuming sexual activity acknowledges the client's concerns while allowing for further discussion. The remaining responses ignore the client's feelings and do not facilitate an ongoing conversation or explore the client's concern.
The nurse is caring for a client who is being discharged after insertion of a permanent pacemaker. The client, an avid tennis player, is scheduled to play in a tournament in 1 week. What is the best advice the nurse can give related to this activity?
"You will need to cancel this activity; you must restrict arm movement above your head for 2 weeks." Explanation: It is important to restrict movement of the arm until the incision heals. The client should not raise the arm above the head for 2 weeks afterward to avoid dislodging the leads. The client must avoid contact sports (e.g., basketball, football, hockey).
The nurse is working with a client with a new onset of atrial fibrillation during a three-month follow-up visit. The healthcare provider is planning a cardioversion, and the client asks the nurse why there is a wait for the treatment. What is the best response by the nurse?
"Your atrial chambers may contain blood clots now, so you must take an anticoagulant for a few weeks before the cardioversion." Explanation: Because of the high risk of embolization of atrial thrombi, cardioversion of atrial fibrillation that has lasted longer than 48 hours should be avoided unless the client has received warfarin for at least 3 to 4 weeks prior to cardioversion. The doctor will not wait for a change in rhythm. Resting the heart will not change the rhythm. There is no delay but safer for the clots to be dissolved with the anticoagulant.
The nurse knows that what PR interval presents a first-degree heart block?
0.24 seconds Explanation: In adults, the normal range for the PR is 0.12 to 0.20 seconds. A PR internal of 0.24 seconds would indicate a first-degree heart block.
The nurse is assigned the following client assignment on the clinical unit. For which client does the nurse anticipate cardioversion as a possible medical treatment?
A client with atrial dysrhythmias Explanation: The nurse is correct to identify a client with atrial dysrhythmias as a candidate for cardioversion. The goal of cardioversion is to restore the normal pacemaker of the heart, as well as, normal conduction. A client with a myocardial infarction has tissue damage. The client with poor perfusion has circulation problems. The client with heart block has an impairment in the conduction system and may require a pacemaker.
The licensed practical nurse is setting up the room for a client arriving at the emergency department with ventricular arrhythmias. The nurse is most correct to place which of the following in the room for treatment?
A defibrillator Explanation: The nurse is most correct to place a defibrillator close to the client room if not in the room. The nurse realizes that clients with ventricular dysrhythmias are at a high risk for fatal heart dysrhythmia and death. A suction machine is used to remove respiratory secretions. Cardioversion is used in a planned setting for atrial dysrhythmias. An ECG machine records tracings of the heart for diagnostic purposes. Most clients with history of cardiac disorders have an ECG completed.
Which of the following medication classifications is more likely to be expected when the nurse is caring for a client with atrial fibrillation?
Anticoagulant Explanation: Clients with persistent atrial fibrillation are prescribed anticoagulation therapy to reduce the risk of emboli formation associated with ineffective circulation. The other options may be prescribed but not expected in most situations.
A nurse provides evening care for a client wearing a continuous telemetry monitor. While the nurse is giving the client a back rub, the client 's monitor alarm sounds and the nurse notes a flat line on the bedside monitor system. What is the nurse's first response?
Assess the client and monitor leads. Explanation: The nurse should assess the client and monitor leads first. It is important that the nurse "treat the client, not the monitor." Ventricular asystole may often appear on the monitor when leads are displaced. The other interventions are not necessary.
The registered nurse reviewed the patient's vital signs and noted a consistent pattern of heart rate recordings between 48 and 58 bpm over a 24-hour period of time. What medication will cause bradycardia?
Atenolol Explanation: Atenolol is a beta-blocker that can lower the heart rate. The other medications stimulate the sympathetic response which will increase heart rate.
The nurse cares for a client with a dysrhythmia and understands that the P wave on an electrocardiogram (ECG) represents which phase of the cardiac cycle?
Atrial depolarization Explanation: The P wave represents atrial depolarization. The QRS complex represents ventricular depolarization. The T wave represents ventricular repolarization. The ST segment represents early ventricular repolarization, and lasts from the end of the QRS complex to the beginning of the T wave.
A client presents to the emergency department via ambulance with a heart rate of 210 beats/minute and a sawtooth waveform pattern per cardiac monitor. The nurse is most correct to alert the medical team of the presence of a client with which disorder
Atrial flutter Explanation: Atrial flutter is a disorder in which a single atrial impulse outside the SA node causes the atria to contract at an exceedingly rapid rate. The atrioventricular (AV) node conducts only some impulses to the ventricle, resulting in a ventricular rate slower than the atrial rate, thus forming a sawtooth pattern on the heart monitor. Asystole is the absence of cardiac function and can indicate death. Premature ventricular contraction indicates an early electric impulse and does not necessarily produce an exceedingly rapid heart rate. Ventricular fibrillation is the inefficient quivering of the ventricles and indicative of a dying heart.
A patient has had an implantable cardioverter defibrillator inserted. What should the nurse be sure to include in the education of this patient prior to discharge? (Select all that apply.)
Avoid magnetic fields such as metal detection booths. Call for emergency assistance if feeling dizzy. Record events that trigger a shock sensation. Explanation: The nurse should instruct the patient to avoid large magnetic fields such as those created by magnetic resonance imaging, large motors, arc welding, electrical substations, and so forth. Magnetic fields may deactivate the device, negating its effect on a dysrhythmia. The patient should call 911 for emergency assistance if a feeling of dizziness occurs. The patient should maintain a log that records discharges of an implantable cardioverter defibrillator (ICD). Record events that precipitate the sensation of shock. This provides important data for the physician to use in readjusting the medical regimen. Throbbing pain is not normal and should be reported immediately. An initial x-ray is indicated prior to discharge, but monthly x-rays are unnecessary.
Which postimplantation instruction must a nurse provide to a client with a permanent pacemaker?
Avoid sources of electrical interference Explanation: The nurse must instruct the client with a permanent pacemaker to avoid sources of electrical interference. The nurse should also instruct the client to avoid strenuous movement (especially of the arm on the side where the pacemaker is inserted), to keep the arm on the side of the pacemaker lower than the head except for brief moments when dressing or performing hygiene, and to delay for at least 8 weeks activities such as swimming, bowling, tennis, vacuum cleaning, carrying heavy objects, chopping wood, mowing, raking, and shoveling snow.
The nurse is providing discharge instructions to a client after a permanent pacemaker insertion. Which safety precaution will the nurse communicate to the client?
Avoid undergoing magnetic resonance imaging (MRI). Explanation: A client with a pacemaker should avoid undergoing an MRI because the magnet could disrupt pacemaker function and cause injury to the client. Disruption is less likely to occur with newer microwave ovens. The client must avoid vigorous arm and shoulder movement only for the first 6 weeks after pacemaker implantation. Airport metal detectors don't harm pacemakers; however, the client should notify airport security guards that he has a pacemaker because its metal casing and programming magnet could trigger the metal detector.
A nurse provides morning care for a client in the intensive care unit (ICU). Suddenly, the bedside monitor shows ventricular fibrillation and the client becomes unresponsive. After calling for assistance, what action should the nurse take next?
Begin cardiopulmonary resuscitation Explanation: In the acute care setting, when ventricular fibrillation is noted, the nurse should call for assistance and defibrillate the client as soon as possible. If defibrillation is not readily available, CPR is begun until the client can be defibrillated, followed by advanced cardiovascular life support (ACLS) intervention, which includes endotracheal intubation and administration of epinephrine. Electrical cardioversion is not indicated for a client in ventricular fibrillation.
A nurse is caring for a client who has been admitted to have a cardioverter defibrillator implanted. The nurse knows that implanted cardioverter defibrillators are used in which clients?
Clients with recurrent life-threatening tachydysrhythmias Explanation: The automatic implanted cardioverter defibrillator (AICD) is an internal electrical device used for selected clients with recurrent life-threatening tachydysrhythmias.
After evaluating a client for hypertension, a health care provider orders atenolol, 50 mg P.O. daily. Which therapeutic effect should atenolol have in treating hypertension?
Decreased cardiac output and decreased systolic and diastolic blood pressure Explanation: As a long-acting, selective beta1-adrenergic blocker, atenolol decreases cardiac output and systolic and diastolic blood pressure; however, like other beta-adrenergic blockers, it increases peripheral vascular resistance at rest and with exercise. Atenolol may cause bradycardia, not tachycardia.
The nurse is assessing a patient with a probable diagnosis of first-degree AV block. The nurse is aware that this dysrhythmia is evident on an ECG strip by what indication?
Delayed conduction, producing a prolonged PR interval Explanation: First-degree AV block may occur without an underlying pathophysiology, or it can result from medications or conditions that increase parasympathetic tone. It occurs when atrial conduction is delayed through the AV node, resulting in a prolonged PR interval.
Which of the following does the nurse recognize as the therapeutic goal of radiofrequency catheter ablation for a client with cardiac dysrhythmias?
Destruction of errant tissue Explanation: The therapeutic goal of radiofrequency catheter ablation is to destroy errant tissue, in hopes of allowing impulse conduction to travel over appropriate pathways. The goal does not include dilation of blood vessels or reperfusion of heart tissue. There is no stimulation of the heart.
The nurse analyzes the electrocardiogram (ECG) strip of a stable patient admitted to the telemetry unit. The client's ECG strip demonstrates PR intervals that measure 0.24 seconds. What is the nurse's most appropriate action?
Document the findings and continue to monitor the patient Explanation: The client's electrocardiogram (ECG) tracing indicates a first-degree atrioventricular (AV) block. First-degree AV block rarely causes any hemodynamic effect; the other blocks may result in decreased heart rate, causing a decrease in perfusion to vital organs, such as the brain, heart, kidneys, lungs, and skin. The most appropriate action by the nurse is to document the findings and continue to monitor the client.
A client has been living with an internal, fixed-rate pacemaker. When checking the client's readings on a cardiac monitor the nurse notices an absence of spikes. What should the nurse do?
Double-check the monitoring equipment. Explanation: One of the reasons for lack of pacemaker spikes is faulty monitoring equipment.
The nurse is preparing a client for upcoming electrophysiology (EP) studies and possible ablation for treatment of atrial tachycardia. What information will the nurse include in the teaching?
During the procedure, the dysrhythmia will be reproduced under controlled conditions. Explanation: During EP studies, the patient is awake and may experience symptoms related to the dysrhythmia. The client does not receive general anesthesia. The EP procedure time is not easy to determine. EP studies do not always include ablation of the dysrhythmia.
A client with an atrial dysrhythmia has come to the clinic for a follow-up appointment and to talk with the health care provider about options to stop this dysrhythmia. What procedure could be used to treat this client?
Elective electrical cardioversion Explanation: Elective electrical cardioversion is a nonemergency procedure done by a physician to stop rapid, but not necessarily life-threatening, atrial dysrhythmias. Chemical cardioversion is not a procedure; it is drug therapy. A Mace procedure is a distractor for this question. Defibrillation is not an elective procedure.
The client has been prescribed procainamide for a dysrhythmia. Which medication side effect will the nurse teach the client to watch for?
Feeling tired Explanation: The side effects of procainamide hydrochloride can include hypotension, GI upset, and feelings of tiredness. Procainamide does not cause hypertension, tachycardia, or a change in mental status.
The nurse is caring for a client who has premature ventricular contractions. What sign or symptom is observed in this client?
Fluttering Explanation: Premature ventricular contractions usually cause a flip-flop sensation in the chest, sometimes described as "fluttering." Associated signs and symptoms include pallor, nervousness, sweating, and faintness. Symptoms of premature ventricular contractions are not nausea, hypotension, and fever.
The nurse reads an athletic client's electrocardiogram. What finding will be consistent with a sinus bradycardia?
Heart rate of 42 beats per minute (bpm). Explanation: The heart rate of 42 bpm is slow but normal when it occurs in athletes with a sinus bradycardia. The PR interval is prolonged at 0.24 seconds, indicating a heart block. The QR interval is prolonged and indicates ventricular delay. The ratio of P to QR should be 1:1 in sinus bradycardia.
The nurse identifies which of the following as a potential cause of premature ventricular complexes (PVCs)?
Hypokalemia Explanation: PVCs can be caused by cardiac ischemia or infarction, increased workload on the heart (e.g., exercise, fever, hypervolemia, heart failure, tachycardia), digitalis toxicity, acidosis, or electrolyte imbalances, especially hypokalemia.
Which rhythm is also termed a ventricular escape rhythm?
Idioventricular rhythm Explanation: Idioventricular rhythm is also called a ventricular escape rhythm.
What is the treatment of choice for ventricular fibrillation?
Immediate bystander CPR Explanation: The treatment of choice for ventricular fibrillation is immediate bystander cardiopulmonary resuscitation (CPR), defibrillation as soon as possible, and activation of emergency services.
A patient is 2 days postoperative after having a permanent pacemaker inserted. The nurse observes that the patient is having continuous hiccups as the patient states, "I thought this was normal." What does the nurse understand is occurring with this patient?
Lead wire dislodgement Explanation: Phrenic nerve, diaphragmatic (hiccupping may be a sign), or skeletal muscle stimulation may occur if the lead is dislocated or if the delivered energy (mA) is set high. The occurrence of this complication is avoided by testing during device implantation.
Which nursing intervention must a nurse perform when administering prescribed vasopressors to a client with a cardiac dysrhythmia?
Monitor vital signs and cardiac rhythm Explanation: The nurse should monitor the client's vital signs and cardiac rhythm for effectiveness of the medication and for side effects and should always have emergency life support equipment available when caring for an acutely ill client. The side effects of vasopressor drugs are hypertension, dysrhythmias, pallor, and oliguria. It is not necessary to place a client flat during or after vasopressor administration. When administering cholinergic antagonists, documentation of the heart rate is necessary.
To evaluate a client's atrial depolarization, the nurse observes which part of the electrocardiogram waveform?
P wave Explanation: The P wave depicts atrial depolarization, or spread of the electrical impulse from the sinoatrial node through the atria. The PR interval represents spread of the impulse through the interatrial and internodal fibers, atrioventricular node, bundle of His, and Purkinje fibers. The QRS complex represents ventricular depolarization. The T wave depicts the relative refractory period, representing ventricular repolarization.
The nurse is assessing vital signs in a patient with a permanent pacemaker. What should the nurse document about the pacemaker?
Pacer rate Explanation: After a permanent pacemaker is inserted, the patient's heart rate and rhythm are monitored by ECG.
A 28-year-old client presents to the emergency department, stating severe restlessness and anxiety. Upon assessment, the client's heart rate is 118 bpm and regular, the client's pupils are dilated, and the client appears excitable. Which action should the nurse take next?
Question the client about alcohol and illicit drug use. Explanation: The client is experiencing sinus tachycardia. Since the client's findings of tachycardia, dilated pupils, restlessness, anxiety, and excitability can indicate illicit drug use (cocaine), the nurse should question the client about alcohol and illicit drug use. This information will direct the client's plan of care. Causes of tachycardia include medications that stimulate the sympathetic response, stimulants, and illicit drugs. The treatment goals for sinus tachycardia is usually determined by the severity of symptoms and directed at identifying and abolishing its cause. The other interventions may be implemented, but determining the cause of the tachycardia is essential.
A patient comes to the emergency department with reports of chest pain after using cocaine. The nurse assesses the patient and obtains vital signs with results as follows: blood pressure 140/92, heart rate 128, respiratory rate 26, and an oxygen saturation of 98%. What rhythm on the monitor does the nurse anticipate viewing?
Sinus tachycardia Explanation: Sinus tachycardia occurs when the sinus node creates an impulse at a faster-than-normal rate. Causes include medications that stimulate the sympathetic response (e.g., catecholamines, aminophylline, atropine), stimulants (e.g., caffeine, nicotine), and illicit drugs (e.g., amphetamines, cocaine, Ecstasy).
A client has been diagnosed with atrial fibrillation and has been prescribed warfarin therapy. What should the nurse prioritize when providing health education to the client?
The need to have regular blood levels drawn Explanation: One drawback of warfarin therapy is the need to have blood levels drawn on a regular basis. The medication does not need to be taken on an empty stomach, and the client does not have to sit upright. Adequate fluid intake is useful in a general way, but the need for fluids is not increased by taking warfarin.
The nurse documents that a client is having a normal sinus rhythm. What characteristics of this rhythm has the nurse assessed?
The sinoatrial (SA) node initiates the impulse. Explanation: The characteristics of normal sinus rhythm are heart rate between 60 and 100 beats per minute; the SA node initiates the impulse; the impulse travels to the AV node in 0.12 to 0.2 seconds; the ventricles depolarize in 0.12 seconds or less; and each impulse occurs regularly.
A patient who had a myocardial infarction is experiencing severe chest pain and alerts the nurse. The nurse begins the assessment but suddenly the patient becomes unresponsive, no pulse, with the monitor showing a rapid, disorganized ventricular rhythm. What does the nurse interpret this rhythm to be?
Ventricular fibrillation Explanation: The most common dysrhythmia in patients with cardiac arrest is ventricular fibrillation, which is a rapid, disorganized ventricular rhythm that causes ineffective quivering of the ventricles. No atrial activity is seen on the ECG. The most common cause of ventricular fibrillation is coronary artery disease and resulting acute myocardial infarction. Ventricular fibrillation is always characterized by the absence of an audible heartbeat, a palpable pulse, and respirations.
A client has a medical diagnosis of an advanced first-degree atrioventricular block and is symptomatic. What initial treatment will the nurse be prepared to complete?
administer an IV bolus of atropine Explanation: The initial treatment of choice is an IV bolus of atropine. If the client does not respond to atropine, has advanced AV block, or has had an acute MI, temporary pacing may be started. A permanent pacemaker my be necessary if the block persists. Cardioversion is done with a fast heart rate. Furosemide will be given for fluid overload. Cardiac catheterization is administered for chest pain.
The nurse is caring for a client who is displaying a third-degree AV block on the EKG monitor. What is the priority nursing intervention for the client
alerting the healthcare provider of the third-degree heart block Explanation: The client may experience low cardiac output with third-degree AV block. The healthcare provider needs to intervene to preserve the client's cardiac output. Monitoring the blood pressure and heart rate are important, but not a priority. The identification of a code status during a heart block is not appropriate. IV fluids are not helpful if the heart is not perfusing.
The nurse is caring for a client with second-degree atrioventricular block, Type I with symptomatic bradycardia. What is the most likely medication the nurse will administer?
atropine sulfate Explanation: Atropine blocks acetylcholine at parasympathetic neuroeffector sites and blocks vagal stimulation. The client will be treated with an anticholinergic that blocks the effects of the vagal nerve. Atenolol and nadolol are beta blockers that are used for chest pain, myocardial infarction, and hypertension. Diltiazem is a calcium channel blocker used to treat angina or slow the heart rate.
The nurse witnesses a client experiencing ventricular fibrillation. What is the nurse's priority action?
defibrillation Explanation: Advanced cardiac life support recommends early defibrillation for witnessed ventricular fibrillation. A cardioversion is used with a client who has a pulse. Atropine is used for bradycardia and dobutamine is an inotropic medication used to increased cardiac output.
A client asks the nurse what causes the heart to be an effective pump. The nurse informs the client that this is due to the:
inherent rhythmicity of cardiac muscle tissue. Explanation: Cardiac rhythm refers to the pattern (or pace) of the heartbeat. The conduction system of the heart and the inherent rhythmicity of cardiac muscle produce a rhythm pattern, which greatly influences the heart's ability to pump blood effectively.
The nurse analyzes a 6-second electrocardiogram (ECG) tracing. The P waves and QRS complexes are regular. The PR interval is 0.18 seconds long, and the QRS complexes are 0.08 seconds long. The heart rate is calculated at 70 bpm. The nurse correctly identifies this rhythm as
normal sinus rhythm. Explanation: The electrocardiogram (ECG) tracing shows normal sinus rhythm (NSR). NSR has the following characteristics: ventricular and atrial rate: 60 to 100 beats per minute (bpm) in the adult; ventricular and atrial rhythm: regular; and QRS shape and duration: usually normal, but may be regularly abnormal; P wave: normal and consistent shape, always in front of the QRS; PR interval: consistent interval between 0.12 and 0.20 seconds and P:QRS ratio: 1:1.
A client is diagnosed with a dysrhythmia at a rate slower than 60 beats/minute with a regular interval between 0.12 and 0.20 seconds. What type of dysrhythmia does the client have?
sinus bradycardia Explanation: Sinus bradycardia is a dysrhythmia that proceeds normally through the conduction pathway but at a slower than usual (less than 60 beats/minute) rate.
