True
You should drink eight 8-ounce glasses of water per day. That's half a gallon of water (about 2 liters).
Answer:
1. spontaneously
2. resting potential
3. action potentials
4. pacemaker potentials
5. K+
6. Na+
7. into
8. Ca+
Explanation:
Pacemaker cells (also known as sinoatrial node cells) are cells that generate rhythmic impulses and set the pace for blood pumping in the heart. These cells have the ability to rhythmically depolarize and initiate action potentials. In pacemaker cells, Ca2+ and Na+ levels are higher in the extracellular environment, while K+ concentration is higher intracellularly. The pacemaker action potentials have three phases: 1-depolarization, where membrane potential reaches -40 mV and voltage-gated Ca2+ channels open, 2-repolarization, where voltage-gated Ca2+ channels close and voltage-gated K+ channels open, and finally 3-gradual depolarization, which is caused by the slow influx of Na+ ions.
Answer:
The best answer choice for the question: The number of milligrams of aspirin that should be administered is:___, would be, A: 19 mg.
Explanation:
First, it must always be remembered that dosages of any type of medication will be vastly different when administered to children, than when administered in adults. In children, the body mass of the child, as well as the miligrams of a medication, and the number of times it must be given, have to be computed so that the exact mgs are administered. If too few is given, then in this case the baby´s fever will not break. If too much, severe repercussions can follow, due to overdose. In essence, the first step here is that the body of the child in pounds must be transfomed to its equivalent in kgms. Second, the body weight of the child will be multiplied by the total dose ordered. Since the kilograms of this child are 3.86, this multiplied by 5.0 will give us a total of 19 mgs. So, the infant must receive 19 mg of aspirin a day to break the fever.
