Answer:
The answer to the question: The movement of ions through their channels require a discharge of the capacitance, is, true.
Explanation:
In order for cells, muscular and neuronal, to perform their activities, they need to generate action potentials, that will permit these activities. In order for an action potential to happen, a cell´s membrance must be charged, or rather, its polarity must be changed, so that the cell can be charged and then fire. Usually, cells remain in a resting membrane state, in which, the extracellular matrix remains positive, while the intracellular space remains positive, due to ion, and anion presence in either. In order for the action potential to happen, these polarities are reversed through a series of steps in which ions, particularly potassium and sodium, sometimes calcium, will enter and exit the cell´s membrane to change this polarity. But in order for this process to take place, first a current, or stimulation, must motivate the cell to start the process. The capacitance is the capability of a cell to be ready to be activated or de-activated when stimulated, meaning, to be charged and discharged, when necessary. In order for this capacitance to permit the process of action potential formation, it needs to be discharged first, and this is done through the stimulus, which orders the cell´s membrane to initiate depolarization by opening up the ion channels. This is why the answer is true.
-Deliver 1 ventilation every 3 to 5 seconds
-Check the pulse and breathing about every 2 minutes
Answer:
The CPT code for second trimester obstetrical ultrasound with a fetal anatomical evaluation to obtain fetal heartbeat and fetus’s position is CPT code 76811.
Explanation:
According to the Society for Maternal-Fetal Medicine, the CPT code 76811 ultrasound is a pregnant uterus real-time ultrasound complete with image documentation performed to diagnose fetal anomalies. It is done during the second trimester of pregnancy with various indications like twin, triplet, or quadruplet pregnancy; suspected fetal any genetic or anatomic anomalies; maternal gestational diabetes, obesity etc. Fetal anatomical structures like abdomen, chest (heart), extremities, head, face and neck, spine, and position of the fetus are examined under this ultrasound. This ultrasound provides fetal 4-chamber heart view with heart activities to identify any fetal or congenital heart defects
High-fructose corn syrup, sorbitol and sucrose are the nutritive sweeteners.
Nutritive sweeteners, conjointly referred to as caloric sweeteners or sugars, give energy within the style of carbohydrates. Non-nutritive sweeteners, conjointly known as sugar substitutes or artificial sweeteners, are alternatives that contain zero or terribly low amounts of carbohydrates or energy.
Sorbitol is a form of carbohydrate known as a sugar alcohol, or polyol. Sorbitol contains regarding third fewer calories than sugar and is sixty % as sweet. Sorbitol occurs naturally in a very sort of berries and fruits (e.g., apples and blackberries).
Ingestion an excessive amount of high-fructose corn syrup may promote weight gain, and neither sweetener has any wholesome worth on the far side the calories.
