Cómo afecta la cantidad de medicamiento al nivel de fiebre de un paciente??

1 answer:

4 0

La fiebre es la temperatura corporal anormalmente alta. Por lo general, se define como tres lecturas de temperatura oral superiores a 38 ºC o 100.4 ºF en un período de 24 horas, o una lectura de temperatura superior a 38.5 ºC o 101.3 ºF. La fiebre es la respuesta del cuerpo a una infección. Sin embargo, sólo en la mitad de todos los pacientes con cáncer que desarrollan fiebre es posible encontrar un origen claro de la infección.

La fiebre es particularmente preocupante si ocurre en un momento en que se sabe o se espera que el nivel de leucocitos sea bajo (en el nadir). Durante ese tiempo, las defensas normales del cuerpo contra las infecciones están bajas y es necesario evaluar la fiebre más detenidamente de inmediato.

A veces, la quimioterapia y la fiebre guardan relación, porque los pacientes que reciben tratamientos de quimioterapia y tratamiento biológico pueden tener fiebre como parte del "síndrome seudogripal". La fiebre asociada con el síndrome seudogripal usualmente alcanza los 40 ºC o 104 ºF y suele aumentar después de un escalofrío fuerte. Este comportamiento es similar al cuadro clínico que presenta una sepsis (una infección en la sangre), de manera que es importante que los pacientes que reciben tratamiento biológico conozcan la evolución habitual de la fiebre después del tratamiento.

A population of 150 fish have two alleles for the size of a black spot on their sides: large spot alleles and small spot alleles

MAVERICK [17]

Answer:

1. genetic drift; 2. natural selection; 3. gene flow; 4. natural selection

Explanation:

1. A fish net captures twenty fish, all who happened to have large spots: 

The mechanism of evolution that is playing out in this situation is most likely genetic drift. Genetic drift occurs when a random change occurs, resulting in the selection of a number of individuals by chance, rather than based on their level of fitness. The fish with large spots allele were selected against by chance, not necessarily because the fish with the small spot alleles were better fitted.

2. Small spotted fish escape from predators better:

The situation here is natural selection. The small spotted fish possess a greater fitness as they become well adapted to escaping from predators better than the large spotted fish, which gives confers on them a greater fitness to be selected for against the large spotted fish.

3. 15 large spotted fish move into this population:

The movement or introduction of new individuals i nto a population is what is referred to as gene flow in evolution, which is another mechanism of evolution that changes the allele frequency of the original population.

4. Fish-eating birds catch large spotted fish more easily:

This is another example of natural selection. The small spotted fish possess a greater fitness which makes them not easily preyed upon by Fish-eating bird easily, compared to large spotted fish. Natural selection favors the fish with small spotted alleles against the large spotted fish, and as a result, more small spotted fish would survive and reproduce more offspring with the small spotted alleles compared to those with large spotted alleles.

In a 1h nmr spectrum, the signal for a vinyl proton is generally more downfield than an alkyl proton because _____.

tamaranim1 [39]

In an 1H NMR spectrum, the signal for vinyl proton is generally more downfield than an alkyl proton because the additional magnetic field created by the π electrons causes the nearby protons to resonate at a higher frequency.

<h3>What is meant by NMR? </h3>

NMR stands for nuclear magnetic resonance. In this technique, various molecules are studied by studying the interactions of their nucleus with electromagnetic radiations and then recording their radiofrequency.

The nuclei in this case are placed in a strong magnetic field.

This effect was discovered by Zeeman. It is used to study the magnetic properties of nuclei of certain atoms so that they can be appropriately utilized.

Therefore, In a 1H NMR spectrum, the vinyl proton signal is more downfield than an alkyl proton because the additional magnetic field created by the π electrons causes the nearby protons to resonate at a higher frequency.
