68WM6 EKG/Lymph
Cardiac Monitoring and the Lymphatic System
| Question | Answer |
|---|---|
| Electrocardiography (EKG) Device | used to measure cardiac electrical current |
| Electrical currents will provide important information about____and can identify potential problems. | heart contractions |
| The EKG is key in the assesment of____and can often indicate the urgency of treatment. | cardiopulmonary sypmtoms |
| Electrocardiogram (ECG) | Graphic record of heart's electrical activity. |
| The body acts as a conductor of electrical energy and the____is the largest generator of electrical energy. | heart |
| Electrodes placed on skin can detect | total electrical activtity within heart. |
| Electrical impulses on skin surface have very low voltage measured in_____. | milivolts |
| Positive impulses appear as | "upward" deflections on graph paper or monitor screen. |
| Negative impulses appear as | "downward" deflection on graph paper or monitor screen. |
| Asystolic cardiac rythym displays as | a "flat" (isoelectric) line |
| Each pair of electrodes is called a.... | Lead |
| Badic Cardiac Monitoring uses how many leads? | 3 |
| Three types of ECG leads are... | 1.Bipolar 2.Augmented 3. Precordial |
| The most frequently used lead is the | Bipolar Limb Lead |
| Bipolar Leads provide how many views of the heart's electrical activity? | Three Views |
| Where are Bipolar Limb Leads placed? | Left Arm, Right Arm, and Left Leg |
| Routine ECG monitoring uses | 1 lead |
| The Lymphatic System removes excess fluid from | interstitial spaces and returns it to the blood stream. |
| The Lymphatic System absorbs | digested fats and transports them to the venous circulation. |
| Immunity | Generalized and targeted attacks against foreign particles (pathogens). |
| Define Lymphatic Pathways | Vessels that transport fluid which begin a s microscopic capillaries, gain in size as vessels merge, and end in ducts that empty into the venous system. |
| Lymphatic Caplillaries | extend into interstitial spaces forming complex networks that parallel those of blood capillaries. |
| Lymphatic capillaries are composed of____that allow fluid to enter lymphatic capillaries. | thin walls |
| Lymphatic Vessels are similar to | veins |
| Lymphatic Vessels contain valves to prevent backflow of..... | fluid |
| Lymph Nodes | specialized organs located along the lyphatic pathways that contain large numbers of lymphocytes and macrophages that fight invading microorganisms. |
| Lymph Nodes occur singly or | in groups associated with the mucuous membranes of the respiratory and digestive tracts. |
| Locations of the major lymph nodes include | cervical nodes, axillary nodes, inguinal nodes. |
| A major funciton of lymph nodes includes: | filtering portentially harmful particles from lymph before returning it to the bloodstream. |
| Lymph nodes are responsible for | immune surveillance. |
| I didn't see her talking s**t when prior service talked....yah big balls good job time for another case of midol! | Define Command Private Major..... |
| Fluid that occupies the spaces between the cells and acts as their immediate environment | Interstitial fluid (ISF) |
