    B. 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.

      S

    • B.

      P

    • C.

      R

    • D.

      U

    Correct Answer
    B. P
    Explanation
    The correct answer is "p". In an electrocardiogram (ECG), the P wave represents atrial depolarization, which is the electrical activation of the atria. This wave shows the spread of electrical impulses through the atria, leading to their contraction and the pumping of blood into the ventricles. By analyzing the shape, duration, and amplitude of the P wave, healthcare professionals can assess the health and functioning of the atria.

    A QRS measurement of less than ______ seconds indicates a supraventricular pacemaker.

    • A.

      .12

    • B.

      .13

    • C.

      .14

    • D.

      .15

    Correct Answer
    A. .12
    Explanation
    A QRS measurement of less than .12 seconds indicates a supraventricular pacemaker. This is because a supraventricular pacemaker typically originates in the atria, which are located above the ventricles. The QRS complex represents the electrical activity of the ventricles, so a shorter QRS duration suggests that the electrical signal is not originating from the ventricles but rather from above them. Therefore, a QRS measurement of less than .12 seconds is indicative of a supraventricular pacemaker.

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

    • A.

      Agonal

    • B.

      Asystole

    • C.

      Agonist

    • D.

      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.

    A ______ occurs when the atria and the ventricles are beating independently.

    • A.

      1st degree block

    • B.

      2nd degree block

    • C.

      3rd degree block

    • D.

      Ventricular flutter

    Correct Answer
    C. 3rd degree block
    Explanation
    A 3rd degree block occurs when the atria and the ventricles are beating independently. In this condition, there is a complete blockage of electrical signals between the atria and ventricles, leading to the two chambers beating at different rates. The atria may be beating normally, while the ventricles may be beating slower and less efficiently. This can result in symptoms such as dizziness, fainting, and shortness of breath, and may require medical intervention such as a pacemaker.

    Contaminated objects that can penetrate the skin (e.g. needles, scalpels, broken glass, etc.) must be disposed of in ______.

    • A.

      Metal trach can

    • B.

      Leak proof container

    • C.

      Contaminated sharps containers

    • D.

      No answer is correct

    Correct Answer
    C. Contaminated sharps containers
    Explanation
    Contaminated objects that can penetrate the skin, such as needles, scalpels, and broken glass, need to be disposed of in containers specifically designed to handle sharps. These containers are called contaminated sharps containers. They are leak-proof and designed to prevent any accidental injuries or exposure to hazardous materials. Metal trash cans or regular leak-proof containers may not provide the necessary safety measures for handling and disposing of contaminated sharps. Therefore, the correct answer is contaminated sharps containers.

    The chances of becoming infected with HBV or HCV from a work-related exposure are much greater than that of becoming infected with HIV from a work-related exposure.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the chances of becoming infected with HBV or HCV (hepatitis B or C viruses) from a work-related exposure are indeed higher compared to the chances of becoming infected with HIV (human immunodeficiency virus) from a work-related exposure. This is because HBV and HCV are primarily transmitted through blood-to-blood contact, which is more likely to occur in certain work environments such as healthcare settings where there is a higher risk of exposure to blood and bodily fluids. On the other hand, HIV is primarily transmitted through sexual contact, sharing needles, or mother-to-child transmission.

    • C.

      Touching non-intact skin without gloves

    • D.

      All answers are correct

    Correct Answer
    D. All answers are correct
    Explanation
    All answers are correct because HBV, HCV, and HIV can be transmitted through sharps injuries, splash of blood/body fluids to the mucous membranes, and touching non-intact skin without gloves. These activities can result in direct contact with infected blood or bodily fluids, which can contain the viruses and lead to transmission of the diseases. It is important to take necessary precautions and follow proper infection control protocols to minimize the risk of transmission in healthcare settings.
