Identifying Dysrhythmias Sinus Rhythm (Exam
Questions and Answers) Updated 2026/2027 | Graded
A+ | 100% Correct.
causes of sinus tachycardia correct answers noncardiac causes
such as exercise or a highly stressful or emotional state
Pain, anxiety, fever, dehydration, hemorrhage
Medications such as atropine, or substances such as caffeine
nicotine, etc.
clinical consequences of sinus tachycardia correct answers
increased oxygen demand in the myocardial tissues.
decrease in stroke volume, cardiac output, and coronary
perfusion.
patient sensation of the hear beating faster.
lightheadedness, chest pain dyspnea, palpitations, or a sensation
of a "pounding in the chest," which may occur with more rapid
rate.
patient management of sinus tachycardia correct answers aimed
at managing the underlying cause. If the patient is dehydrated,
administer fluids. if caused by hemorrhage stop hemorrhage and
replace blood and volume as indicated.
, beta blockers and calcium channel blockers may be administered
to a symptomatic patient.
causes of sinus bradycardia correct answers noncardiac causes
such as sleep, hyperkalemia, hypothermia, hypothyroidism, and
increased intracranial pressure
Well-conditioned athletes often have slower heart rates as their
heart becomes more efficient.
Medications such as digoxin (Lanoxin), lithium (Lithobid), beta
blockers (Lopressor), calcium channel blockers (Cardizem), and
some antidysrhythmic agents such as sotalol (Betapace), or
amiodarone (Pacerone).
Clinical consequences of Sinus Bradycardia correct answers
Often asymptomatic and doesn't require treatment.
If symptomatic, may have signs of a decreased cardiac output
such as hypotension, decreased level of consciousness, or chest
pain.
Patient Management of sinus bradycardia correct answers When
patients are symptomatic, it is important to provide prompt
treatment. The key is to determine the underlying cause and
manage that. If immediate intervention is required,
transcutaneous pacing may be initiated. Medications such as
atropine or epinephrine may also be used if necessary until
transcutaneous pacing is available.
