Answer:

Romano-Ward syndrome (RWS) is a form of long QT syndrome, a heart condition that causes the heart muscle to take longer to recharge between beats than usual.

Explanation:

The heart muscle (myocardium) has the ability to contract and relax in a very precise rhythm so that each cavity, in order, is filled and then empties of the blood it contains. Romano-Ward syndrome is the most common form (autosomal dominant form) of long QT syndrome characterized by an abnormality of cardiac electrical activity that can be diagnosed by recording the electrical impulses of the heart. Despite having a normal anatomy, the heart has electrical dysfunction (abnormally long QT interval) .This syndrome is associated with an increased risk of syncope (fainting), loss of consciousness, heart rhythm disturbances, and even cardiac arrest, which can occur due to efforts or the administration of certain medications. The most frequent causes of the syndrome are mutations in the KCNQ1, KCNH2 and SCN5A genes (these encode proteins that form channels through the cell membrane), these channels transport ions such as potassium and sodium, inside and outside the cells. In heart muscle cells, these ion channels play critical roles in maintaining the heart's normal rhythm.

A dose of aspirin of 5.0 mg per kilogram of body weight has been prescribed to reduce the fever of an infant weighing 8.5 pounds
Vladimir [108]

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.
