HEALTHSTREAM TELEMETRY EXAM 2023/2024

HEALTHSTREAM TELEMETRY EXAM 2023/2024 Pace Maker of the Heart - CORRECT ANSWER-The Sino Atrial node is also known as the 100/60 -138/89 - CORRECT ANSWER-Normal BP range is -0.1 eV for each box in the vertical direction -typically there are 10 boxes in the vertical direction for QRS complexes, adding up to 1.0 eV - CORRECT ANSWER-The vertical lines in each of the boxes indicate: Coreg and epinephrine - CORRECT ANSWER-What medication can change Atrial fibrillation to a sinus rhythm? 140-250 bpm - CORRECT ANSWER-What is the heart rate with a SVT? -Stimulate the sympathetic nervous system, which is a division of the somatic nervous system -increase the heart rate -increase blood supply to the brain, heart, lungs and kidney -cause the pupils to dilate - CORRECT ANSWER-Medications such as epinephrine and adrenaline do what? Count the small boxes between two regular R peaks and divide them into 1500 - CORRECT ANSWER-There are several ways to calculate a heart rate, however the most exact method entails: P wave - CORRECT ANSWER-Atrial depolarization and activation causes which wave to emerge after the resting phase? digoxin - CORRECT ANSWER-Which of the medications is used to treat CHF, and can also cause hypokalemia? QRS = 0.08-0.12 sec PR = 0.12-0.20 sec QT = 0.36 - 0.44 sec - CORRECT ANSWER-What are the measurements of QRS, PR, and QT? beat slower - CORRECT ANSWER-The parasympathetic nervous systems causes the heart to ..... slower - CORRECT ANSWER-With respect to a heart rhythm that contains the P,Q, R, S and T wave, the wider the QRS the _____________________ the heart rate. heart block - CORRECT ANSWER-Damage to the AV node, essentially the entire conduction system is blocked and the ventricles must resort to contracting at an intrinsic rate which is a much slower rate. 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. Major site of blood pressure regulation and blood flow to body parts. Orthostatic hypotension - CORRECT ANSWER-Dizziness due to sudden changes in posture (usually found in elderly), cause by slow nervous system response. When you suddenly get up from a resting position, your blood pressure drops. Angiogram - CORRECT ANSWER-Diagnostic technique using radiopaque dye to show blood vessel blockage/damage. preload and afterload - CORRECT ANSWER-What influences stroke volume? stroke volume - CORRECT ANSWER-amount of blood ejected from the left ventricle with each heartbeat QT - CORRECT ANSWER-The _____________ interval measured from the beginning of the QRS complex to the end of the T wave. ventricular - CORRECT ANSWER-If you do not have a "P" wave, the rhythm is considered to be: Notify the patient's nurse immediately, due to downward trending and decreasing O2 saturation levels - CORRECT ANSWER-You have just begun your shift and you have 30 patients monitor strips to watch. 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?
