A patient with a heart rate of 38 beats/min is pale, dizzy, and nearly faints when sitting up. Which interpretation is most appropriate?

  1. A

    The low rate requires no action unless the patient loses consciousness.

  2. B

    The symptoms may indicate reduced blood flow to the brain from a poorly tolerated slow rhythm.

  3. C

    Dizziness cannot be related to cardiac output while the patient is awake.

  4. D

    Wait until the next scheduled vital-sign check.

    A stable rhythm variation during sleep.

A monitor alarms for a very rapid rhythm, but the patient is talking and appears comfortable. What should the nurse do first?

  1. A

    Assume the alarm is artifact and silence it.

  2. B

    Assess the patient and verify the rhythm using the monitor tracing and a pulse check.

  3. C

    Begin chest compressions immediately.

  4. D

    Leave the room to find the provider before checking the patient.

    Call for emergency help.

  2. B

    Begin CPR.

  3. C

    Recheck the rhythm in five minutes before acting.

  1. A

    Reduced pumping effectiveness with possible heart-failure congestion.

  2. B

    Improved cardiac output caused by the faster rate.

  3. C

    An isolated skin problem unrelated to circulation.

  2. B

    Mild awareness of the heartbeat.

  3. C

    A stable, irregular pulse with no symptoms.

Why is atrial fibrillation associated with an increased risk of embolic stroke?

  1. A

    It directly blocks blood flow through the carotid arteries

  2. B

    Blood may pool in the atria, increasing the chance of clot formation and embolic stroke

  3. C

    It always causes a stroke within hours

  4. D

    It increases stroke risk only when the ventricular rate is slow
