ADN260 "PERFUSION" [ISB-QUIZ]
When providing a temporary pacemaker to a patient, you should observe what on the ECG to determine if the pacemaker has capture?
"A pacer spike followed by a QRS complex" Ventricular demand pacing appears on the electrocardiogram (ECG) as a single pacemaker spike followed by a QRS complex
The nurse is caring for a group of clients on a Telemetry unit. When providing client education, which client will the nurse determine most needs information regarding preventing pulmonary embolism (PE)?
"A woman who frequently flies to Europe" Individuals who engage in prolonged and frequent air travel are at higher risk for PE due to the dependent position of the legs during long air flights.
The nurse visits the home of a client with a newly inserted permanent pacemaker. Which observation indicates that the client would benefit from additional teaching about the device?
"Cell phone in shirt pocket over the pacemaker" The client should be informed of electromagnetic interference restrictions, which include not placed a cell phone over the generator.
You notice that your patient monitor is showing asystole; what is your first coarse of action?
"Check the patient" This is the first course of action since the patient is on a monitor (a machine), assess the patient for matching the data on the monitor screen.
The QRS complex on an ECG tracing indicates what?
"Depolarization of the Ventricles" Ventricular depolarization (activation) is depicted by the QRS complex
A client is prescribed 3-lead telemetry to monitor atrial fibrillation. Which lead approach should the nurse use to obtain the best assessment of this client's atrial functioning?
"Lead II" Atrial activity is best detected in Lead II.
A telemetry nurse assesses a patient who has wide QRS complexes and a heart rate of 35 beats/min on the cardiac monitor. Which assessment would the nurse complete next?
"Level of consciousness" A heart rate of 40 beats/min or less with widened QRS complexes could have hemodynamic consequences. The patient is at risk for inadequate cerebral perfusion. The nurse would assess for level of consciousness, light-headedness, confusion, syncope, and seizure activity. Although the other assessments should be completed, the patient's level of consciousness is the priority
A new graduate is using an automated external defibrillator (AED) for a client who was discovered without a pulse. For which reason should the charge nurse intervene?
"Placing electrode pads below the right clavicle and above the left nipple" The electrode pads should be located below the right clavicle and below the left nipple.
The nurse evaluates the ability of the UAP to complete a 12-lead electrocardiogram for a client. Which lead placement should the nurse correct before the measurement is recorded?
"V6 placed at the fifth intercostal space, left midclavicular line" V4, not V6, should be placed at the fifth intercostal space, left midclavicular line.
When placing a patient on a standard three lead ECG, where are the leads placed?
"White to Right Shoulder, Black to Left Shoulder and Red to Left Upper Abdominal Area" For monitoring purposes with the three-lead system, the white electrode is placed just below the clavicle (collarbone) on the right shoulder. The white lead has a negative polarity. The red electrode is placed below the left pectoral muscle near the apex of the heart. The red lead has a positive polarity. The black electrode is connected below the left clavicle near the shoulder. The black electrode switches polarity dependent on the lead chosen.
