Which clinical manifestation may occur during the acute viral infection stage of human immunodeficiency virus infection

olga_2 [115]

Flu-like Symptoms may occur during the acute viral infection stage of human immunodeficiency virus infection.

The initial stage of HIV infection is known as acute HIV infection, and it typically appears 2–4 weeks after HIV infection. Some people experience flu-like symptoms at this time, including fever, headache, and rash. HIV multiplies quickly during the acute stage of infection and spreads all over the body.

The immune system's infection-fighting CD4 cells (CD4 T lymphocytes) are attacked and destroyed by the virus. The risk of HIV transmission significantly rises during the acute HIV infection stage due to the extremely high HIV blood levels. If ART is initiated at this point, a person might have major health benefits.

After the shock is delivered (if advised), you should continue giving CPR until which of the following

s344n2d4d5 [400]

All the above.

The person shows an obvious sign of life, another trained responder or EMS personnel take over and you are too exhausted to continue.

When someone's breathing or heartbeat have stopped due to an emergency, such as a heart attack or a near-drowning, cardiopulmonary resuscitation (CPR) can help save their life.
The American Heart Association advises performing quick, forceful chest compressions to begin CPR.
In an emergency, cardiopulmonary resuscitation (CPR) can help save a person's life if their breathing or heart stops.
A person is in cardiac arrest when their heart stops beating.
The heart is unable to pump blood to the rest of the body during cardiac arrest, including the brain and lungs.
The acronym "CAB" makes it simple to remember the three essential components of CPR: compressions, airway, and breathing.
"C" stands for compressions. Compressing your chest can improve blood flow to your heart, brain, and other organs.
Before giving two rescue breaths during CPR, 30 chest compressions are given.

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 poun

MAXImum [283]

Answer:

19.3 mg are needed

Explanation:

You can go about solving this in two different ways the first way/ hardest way is to convert the aspirin dose from mg/kg body weight to mg/ lbs body weight and then multiply by the 8.5 lbs body weight. The second/ easier way to get the answer would be to convert the infants body weight from lbs to kg. Then, multiply that by the dose, which will give you 19.3 mg. The math for that is below. Remember always start with the information that you know, to find the information that you don't know.

$\frac{8.5 \: lbs}{} \times \frac{1.0 \: kg}{2.205 \: lbs} \times \frac{5.0 \: mg}{kg} \\ = 19.27mg$

Hope this helps. If not just post a message and I will get back to you! :)
