Patients with suspected strokes must be assessed within 10 minutes of arrival in the emergency department by the stroke team and other experts. Within 10-25 minutes, the CT scan must be completed, and within 45 minutes it must be read.
Hospital need to Obtain a 12-lead ECG and perform neurologic screening assessment. Do not delay CT, obtain CT without contrast within 20 minutes of patient arrival. A neurologic assessment by the stroke team or designee should be done within 20 minutes of patient arrival to the ED.
A CT scan of the head is usually one of the first tests used for a stroke. A CT scan can show bleeding in the brain or damage to brain cells. The CT scan also can find other problems that can cause stroke symptoms.

To reduce the risk of CVD, saturated fat in the diet should provide less than 7 percent of total calories.
<h3>What is Saturated fat?</h3>
Saturated fats are those type of fats that are highly packed with hydrogen molecules and contains only single bonds in between their carbon molecules.
These saturated fats are made up of low density lipoproteins that increases the risk of cardiovascular disorders (CVD).
Therefore, to reduce the risk of CVD, saturated fat in the diet should provide less than 7 percent of total calories.

Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100
<h3>14.8% of H2O2</h3>
Answer:
<u>Static</u><u> </u><u>friction</u><u> </u><u>:</u>
The frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object.
<u>Rolling</u><u> </u><u>friction</u><u> </u><u>:</u>
Rolling friction occurs when a wheel, ball, or cylinder rolls freely over a surface, as in ball and roller bearings. The main source of friction in rolling appears to be dissipation of energy involved in deformation of the objects.

Como el sodio retiene agua, se expande el volumen de sangre y aumenta la presión arterial. Por otro lado, los riñones controlan la presión arterial de varios modos. Si la presión arterial se eleva, aumenta la eliminación de sal y agua, lo que hace descender el volumen de sangre y normaliza la presión arterial.
english
Since sodium retains water, it expands blood volume and increases blood pressure. On the other hand, the kidneys control blood pressure in several ways. If blood pressure rises, the elimination of salt and water increases, which lowers the volume of blood and normalizes blood pressure.
