    A terminal lethal arrhythmia, or dying heart, is referred to as ______.

    • Agonal

    • Asystole

    • Agonist

    • Agogue

    Correct Answer
    A. Agonal
    Explanation
    An agonal rhythm is a term used to describe an abnormal heart rhythm that occurs in the moments before cardiac arrest or death. It is characterized by irregular, slow, and weak heartbeats. This condition is often seen as a last gasp effort by the heart to maintain circulation before it completely stops. Therefore, "agonal" is the correct answer as it accurately represents the terminal lethal arrhythmia.

    Which artifact is an apprehensive patient likely to have?

    • AC

    • Muscle tremor

    • Interference

    • Wavy baseline

    Correct Answer
    A. Muscle tremor
    Explanation
    An apprehensive patient is likely to have muscle tremor as an artifact. Anxiety and fear can cause involuntary muscle movements, leading to tremors. These tremors can be seen on medical recordings such as electrocardiograms (ECGs) or electromyograms (EMGs). Muscle tremors can interfere with the accuracy of these recordings and may need to be taken into consideration during interpretation.

    When a patient makes abnormal noises while breathing (i.e., snoring sounds), it is called ______.

    • Cheyne-Stokes

    • Irregular

    • Abdominal

    • Stertorous

    Correct Answer
    A. Stertorous
    Explanation
    When a patient makes abnormal noises while breathing, such as snoring sounds, it is referred to as "stertorous." Stertorous breathing is characterized by loud, harsh, and often vibrating sounds during respiration. It is commonly associated with conditions like sleep apnea, nasal congestion, or obstruction in the upper airway.

    Grounding the electrocardiograph is necessary to ______.

    • Reduce muscle voltage artifacts

    • Reduce AC artifact

    • Keep from shocking the patient

    • Keep from shorting out the machine

    Correct Answer
    A. Keep from shocking the patient
    Explanation
    Grounding the electrocardiograph is necessary to keep from shocking the patient. When the electrocardiograph is properly grounded, it ensures that any electrical leakage or faults are diverted safely to the ground, preventing the patient from experiencing electric shocks. This is crucial for the safety and well-being of the patient during the electrocardiogram procedure.
