A 45-year-old man had coronary artery stents placed 2 days ago. Today, he is in severe distress and is reporting "crushing" ches

t discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mm hg, respiratory rate is 28 breaths/min, and oxygen saturation is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. Which condition led to cardiac arrest?

Answer:

In the particular case, acute coronary syndrome (ACS) have occurred in the cardiac arrest. The ACS refers to a condition that arise due to the decrease of blood flow in the coronary arteries, such that the segment of the heart muscle is not able to function properly or dies. Some of the signs and symptoms of ACS are chest pain and discomfort, pain rising in your chest and in the arms, shoulders, neck, or jaw, indigestion, nausea or vomiting, shortness of breath, unusual fatigue, excessive sweating, restlessness, dizziness, or fainting.

Answer:

The given case is a result of acute coronary syndrome.

Explanation:

Acute coronary syndrome is a term given to the three kinds of coronary artery disorder, which are related to the sudden splitting of plaque within the coronary artery. The condition generally results from the accumulation of plaques or fatty deposits in and on the walls of the coronary arteries, that is the blood vessels that transmit nutrients and oxygen to the muscles of the heart. When the deposit of the plaque splits or ruptures, the formation of blood clot takes place. This clot prevents the flow of the blood to the muscles of the heart.

¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón d
NNADVOKAT [17]

Energía.

Explicación:

Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.

Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.

En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.

Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.

Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.

Answer:

Energy.

Explanation:

Generally, electrons revolves continuously in the shells of  atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.

They are needed for chemical reactions of a particular atom with another,through their loses or sharing.

In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.

However, if  certain quantity of energy is supplied  to  such atom, the electron  gains energy and therefore becomes excited.

They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.

Suppose that an arginine residue in the active site of an enzyme was mutated to alanine. As expected, the alanine mutant was ina
Makovka662 [10]

Answer:

Alanine to lysine.

Explanation:

Mutation may be defined as the sudden, heritable change in the genome sequence of an organism. Two main types of mutation are chromosomal mutation and point mutation.

The mutation has occurred in which the arginine is replaced by alanine. The mutation that can restore to wild type is the conversion of alanine with lysine.    Since both arginine and lysine are basic amino acids. They both shows almost similar function and the replacement of lysine with alanine shows the wild type activity.

Thus, the answer is alanine to lysine.

sergiy2304 [10]

Answer:

exocytosis

Exocytosis is the reverse of endocytosis. <em><u>Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules.</u></em> By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.
