Chapter 26 : Caring for Clients With Cardiac Arrhythmias Questions
Question 1 of 5
The nurse is caring for clients on a telemetry unit. Which nursing consideration best represents concerns of altered rhythmic patterns of the heart?
Correct Answer: D
Rationale: The best representation of a nursing concern related to a cardiac arrhythmia is the inability of the heart to fill the chambers and eject blood flow efficiently. Lack of an efficient method to circulate blood and bodily fluids produces a variety of complications such as tissue ischemia, pulmonary edema, hypotension, decreased urine output, and impaired level of consciousness. The other options can occur with arrhythmias, but the cause stemming from the altered pattern is the best answer.
Question 2 of 5
The nurse is caring for a client with an arrhythmia. While assessing the data in the history of the chart, the nurse anticipates the cause of the arrhythmia to be which of the following?
Correct Answer: B
Rationale: The nurse realizes that the most common cause of arrhythmias is ischemic heart disease. When the heart does not obtain sufficient blood to meet demands, the heart works harder to circulate body fluids and becomes inefficient in the process. Problems with the peripheral vessels, narrowing of the aorta and plaque build-up in the vessels may be a component of the disease process but not the best answer.
Question 3 of 5
The nurse is caring for a client on the cardiac unit. The licensed practical nurse on the previous shift reported the following vital signs/assessment information: temperature, 100.6?°F; pulse, 56 beats/minute; respirations 24 breaths/minute; blood pressure, 116/60 mm Hg; pulse oximetry reading, 92%; and with 2+ edema noted in the lower extremities. Prior to 9 AM antiarrhythmic medication administration, which of the following will the nurse reassess?
Correct Answer: B
Rationale: Of the vital signs noted, the pulse rate is found to be abnormal, below 60 beats/minute. Before administering an antiarrhythmic medication, which often slows the heart rate further, the pulse rate would be reassessed, and a rate of 60 beats/minute would need to be obtained.
Question 4 of 5
The licensed practical nurse is co-assigned with a registered nurse in the care of a client admitted to the cardiac unit with chest pain. The licensed practical nurse is assessing the accuracy of the cardiac monitor, which notes a heart rate of 34 beats/minute. The client appears anxious and states not feeling well. The licensed practical nurse confirms the monitor reading. When consulting with the registered nurse, which of the following is anticipated?
Correct Answer: B
Rationale: The licensed practical nurse and registered nurse both identify that client's bradycardia. Atropine sulfate, a cholinergic blocking agent, is given intravenously (IV) to increase a dangerously slow heart rate. Lanoxin is not administered when the pulse rate falls under 60 beats/minute. It is dangerous to wait until the pulse rate increases without nursing intervention or administering additional medications until the imminent concern is addressed.
Question 5 of 5
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?
Correct Answer: C
Rationale: 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.
