  1. The QT interval is the total time taken for ventricular depolarization and repolarization.
    Prolongation of the QT interval:
    a. decreases the risk of lethal dysrhythmias.
    b. usually occurs when heart rate increases.
    c. increases the risk of lethal dysrhythmias.
    d. can only be measured with irregular rhythms.
    ANS: C<\/li>\n\n\n\n
  2. The patient has an irregular heart rhythm. To determine an accurate heart rate, the nurse first:
    a. identifies the markers on the ECG paper that indicate a 6-second strip.
    b. counts the number of large boxes between two consecutive P waves.
    c. counts the number of small boxes between two consecutive QRS complexes.
    d. divides the number of complexes in a 6-second strip by 10.
    1 \/ 3
    ANS: A<\/li>\n\n\n\n
  3. The patient is admitted with a fever and rapid heart rate. The patient\u2019s temperature is 103\u00b0 F
    (39.4\u00b0 C).The nurse places the patient on a cardiac monitor and finds the patient\u2019s atrial and
    ventricular rates are above 105 beats per minute. P waves are clearly seen and appear normal in
    configuration. QRS complexes are normal in appearance and 0.08 seconds wide. The rhythm is
    regular, and blood pressure is normal. The nurse should focus on providing:
    a. medications to lower heart rate.
    b. treatment to lower temperature.
    c. treatment to lower cardiac output.
    d. treatment to reduce heart rate.
    ANS: B<\/li>\n\n\n\n
  4. The nurse is working on the night shift when she notices sinus bradycardia on the patient\u2019s
    cardiac monitor. The nurse should:
    a. give atropine to increase heart rate.
    b. begin transcutaneous pacing of the patient.
    c. start a dopamine infusion to stimulate heart function.
    d. assess for hemodynamic instability.
    ANS: D
    2 \/ 3<\/li>\n\n\n\n
  5. The patient is admitted with sinus pauses causing periods of loss of consciousness. The
    patient is asymptomatic, awake and alert, but fatigued. He answers questions appropriately.
    When admitting this patient, the nurse should first:
    a. prepare the patient for temporary pacemaker insertion.
    b. prepare the patient for permanent pacemaker insertion.
    c. assess the patient\u2019s medication profile.
    d. apply transcutaneous pacemaker paddles.
    ANS: C<\/li>\n\n\n\n
  6. The patient\u2019s heart rate is 165 beats per minute. His cardiac monitor shows a rapid rate with
    narrow QRS complexes. The P waves cannot be seen, but the rhythm is regular. The patient\u2019s
    blood pressure has dropped from 124\/62 to 78\/30. His skin is cold and diaphoretic and he is
    complaining of nausea. The nurse prepares the patient for:
    a. administration of beta-blockers.
    b. administration of atropine.
    c. transcutaneous pacemaker insertion.
    d. emergent cardioversion.
    ANS: D<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[],"tags":[],"class_list":["post-111424","post","type-post","status-publish","format-standard","hentry"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/111424","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/comments?post=111424"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/111424\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=111424"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=111424"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=111424"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
