P wave - CORRECT ANSWER Movement of impulse from SA Node through atrial muscles (contraction of both simultaneously), in an ECG corresponds to depolarization of the atrial fibers (leads to contraction) arteriole - CORRECT ANSWER Smallest artery, have only a few muscle cells wrapped around them.

One of the patient's who was just added, have the following vital signs as displayed on the monitor: O2 Sat: 99% BP: 114/80 Pulse rate: 100 After 15 minutes you see the following changes on your screen: O2 Sat 92% BP 100/60 Pulse rate: 62 As a telemetry technician which of the following steps would you take? conductivity, contractility, automaticity, excitability, permittivity - CORRECT ANSWER The heart has 5 specific characteristics which are..... -sign of the heart slowing down -lack of blood flow to the brain and other organs -lack of iron bound to the heme molecule - CORRECT ANSWER Declining oxygen saturation is an ominous sign for patient's due to: Pericardial sac, epicardium, myocardium, endocardium - CORRECT ANSWER The heart is composed of several layers: These layers consist of the following from outside the heart to the most inner part of the heart 0.04 sec - CORRECT ANSWER How many seconds do each of the small boxes indicate? 1st degree AV block - CORRECT ANSWER P-wave always goes before the QRS complex, but PR interval is prolonged over 0.2 second, or 5 small squares. and is therefore... Rate - CORRECT ANSWER The horizontal lines on the ECG rhythm strip indicate what? atrial kick - CORRECT ANSWER When the AV node holds the impulse to allow the ventricles to fill, this is known as the ....... telemetry - CORRECT ANSWER --Continual observation of the heart's electrical activity Used to identify abnormalities in rate, rhythm, and conduction -Evaluates pacemaker function and responses to various cardiac medications -Allows freedom of movement within a certain area -Ruling Out MI -Recent MI -CHF -Stroke -Unstable BP -Implantation of an AICD or Pacemaker -Uncomplicated arrhythmia -Major surgery - CORRECT ANSWER Name some indications of telemetry -Ensure that electrodes are properly placed and in contact with skin -Interpret cardiac rhythms and anticipate effects on overall condition -Document cardiac rhythm at least every 4 hours -Communicate with patients - CORRECT ANSWER Name the 4 major roles of nurses during telemetry -Alcohol prep- remove dirt and oils -Exfoliation paper (sand paper)- roughs up top layer of skin; lightly rub skin with this paper -Packet of electrodes (not expired; gel should be moist; batteries in) - CORRECT ANSWER 3 preparations before placing electrodes pacemaker - CORRECT ANSWER Never put an electrode on a __________ -Right arm lead- 2nd intercostal space of ribs -Right leg lead- below the lower edge of rib cage; non muscular area (not over abdomen muscles -Left arm lead- 2nd intercostal space -Left leg lead- below the lower edge of rib cage; non muscular area (not over abdomen muscles) -V1 lead- 4th intercostal space; in center - CORRECT ANSWER name the 5 electrodes and their locations Right arm lead- white Right leg lead- green - CORRECT ANSWER Name the colors of: Right arm lead- Right leg lead- Left arm lead- black Left leg lead- red - CORRECT ANSWER Name the colors of: Left arm lead- Left leg lead- brown - CORRECT ANSWER Color of V1 lead Cardiac rhythm - CORRECT ANSWER representation of electrical activity in the heart false Cardiac rhythm DOES NOT necessarily correlate with a functioning, beating heart. - CORRECT ANSWER T or F? If a cardiac rhythm is present,it is a functioning, beating heart true - CORRECT ANSWER T or F? If there is a pulse, there will be a rhythm. electrical signals - CORRECT ANSWER ______________ may be present in the absence of a pulse strip- 1 view/lead full page- 12 viewpoints/leads - CORRECT ANSWER -Number of leads of a rhythm on a "strip" of graph paper -Number of leads on a full page of graph paper, EKG lead - CORRECT ANSWER Term for a viewpoint on an EKG; is an imaginary line deliver vital oxygen and nutrients to the cells - CORRECT ANSWER Without a regular rate and rhythm, the heart may not be able to _____________________________________________ normal sinus rhythm - CORRECT ANSWER Healthy heart; 60-100 beats/minute dysrhythmia - CORRECT ANSWER When the normal rhythm is interrupted, a _________________ occurs by where the electrical signal originates - CORRECT ANSWER how are rhythms named? sinus rhythm - CORRECT ANSWER rhythm which originates from the sinoatrial node or SA node located in the right atrium EKG is a snapshot while telemetry is continuous cardiac monitoring 24/7 until discontinued. - CORRECT ANSWER Difference between EKG and telemetry False! It's important for the nurse to know how to do basic interpretation of a rhythm. The nurse must also learn the implications of cardiac rhythms for individual patients. - CORRECT ANSWER T or F? Nurses are not expected to be able to interpret cardiac rhythms. 1. Identify and examine the p waves (atrial activity) 2. Measure the PR interval 3. Measure the QRS complex (ventricular activity) 4. Identify the rhythm 5. Determine the heart rate 6. Interpret strip - CORRECT ANSWER 6 steps of identification of cardiac rhythm Check vital signs and level of consciousness, complaints. We treat patients NOT just rhythms. If the rhythm does not match the way the person is acting, reevaluate. - CORRECT ANSWER What does it mean to evaluate the patient's condition in correlation with EKG interpretation? normal sinus rhythm - CORRECT ANSWER Expected rhythm in most people Rate: 60-100 beats per minute; Rhythm: regular Sinus bradycardia - CORRECT ANSWER May be normal in certain patients (well-trained athletes or vagal response bearing down or vomiting). Abnormal finding most of the time (drug overdose, heart attack, etc.) Rate: less than 60 beats/minute; Rhythm: regular Sinus Tachycardia - CORRECT ANSWER Faster than normal. Normal in babies and young children. May be caused by psychological or physiological stress, or dysfunction with the conduction system. Rate: >100 and usually <120 Rhythm: regular Sinus Arrythmia - CORRECT ANSWER Not concerning; related to respirations Rate: 60-100 beats/minute Rhythm: irregular Premature Atrial Contraction (PAC) - CORRECT ANSWER Early beat, multiple causes (caffeine, anxiety, substances, certain pathological conditions). If patient is without symptoms, no need to treat. -make the rhythm irregular atrial fibrillation - CORRECT ANSWER Most common dysrhythmia affecting 6 million Americans. Abnormal, increases risk for stroke. Multiple signals from the atria causing them to twitch or fibrillate, resulting in inefficient pumping action of the heart. Wavy disorganized waveform on EKG strip. Blood can pool in atria and become a clot. Rate: may be slow, medium, or fast Rhythm: irregular Atrial flutter - CORRECT ANSWER Abnormal. Atria beat regularly, but faster than usual. The ventricles beat slower due to the body "blocking" the signals. Sawtooth configuration on EKG strip. Same risk factors as Atrial Fibrillation (AFIB). Rate: Atrial rate ranges 250-400 beats per minute Ventricular rate ranges 75-150 beats per minute Rhythm: regular [Show More]
