Answer:

CD4 cells are a type of immune cell found in the human body. These cells protect us from infections. CD4 count is a measurement of the number of CD4 cells in a blood sample. It is also used to monitor the progression of HIV infection.

In an HIV-negative adult, the normal range of CD4 count is 500-1500 mm3.

In AIDS there is the destruction of the blood CD4 lymphocytes by the virus.

Explanation:

CD4 cells are a type of immune cell that is found in the blood. This cell count is a measure of the number of these cells in a milliliter of blood. It is an important indicator of immune health.

When the CD4 count gets lower than 200 mm3 the patient is more prone to get opportunistic infections like rare fungal infections, Tuberculosis, Mycobacterial infections, parasitic infections, etc.

The CD4 count is used to measure to identify an immune deficiency in people.

Research on group processes suggests that if group members start with similar opinions, they will support an option that is more extreme.

<h3>What is Research?</h3>

Research may be defined as the process of methodical examination into and analysis of materials and references in order to demonstrate facts and reach new conclusions.

The complete question is as follows:

A group of five health care professionals is presented with a complex system-based problem in a large hospital and asked to generate multiple possible solutions. Research on group processes suggests that:

  • If group members get along, more options will be discussed and considered.
  • The group is more likely to come up with an effective solution if there is a strong group leader.
  • If group members start with similar opinions, they will support an option that is more extreme.
  • On average, individuals working alone will produce fewer options than when working in a group.

Due to Group polarization, group members start with similar opinions, they will support an option that is more extreme. Statement A and B illustrate the mechanism of group thinking, while statement D represents social loafing.

Therefore, the correct option for this question is C.

Answer:

The best answer to your question: Which type of neuroglia would play a role in controlling glutamate levels in the chemical environment, would be: Astrocytes.

Explanation:

From among the neuroglia, or support cells in the brain, whose purpose is to aid neurons in their different functions, astrocytes are not just one of the most numerous, but also one of the most vital for neuronal support. Amongst one of their most central functions is to help in the control of neurotransmitter emition and retention in the synaptic cleft, between two communicating neurons, and therefore, helps regulate the responses from post-synaptic, and pre-synaptic neurons. It is also responsible for clearing up the presence of ions in the extracellular space, and producing ATP, which regulates the amount of neurotransmitters that are released, and taken, by pre-synaptic, and post-synaptic neurons.

In ALS (Amyotrophic Lateral Sclerosis) the issue with glutamate, a neurotransmitter that excites post-synaptic neurons into releasing excess amounts of calcium, is that this hyper-excitatory response leads neurons, particularly motor neurons, to die, and this is what causes ALS. It has been found through research that astrocytes have to do in this process, but it is not clear yet whether there is a failure in their control system, as ALS is still a condition that is very much under study and still without a cure.

Answer:

4ml

Explanation:

80 × 0.25 = 20

Patient will need 20mg/day;

There are 50mg in 10ml, and we the patient needs 20mg so we can use ratios;

50 : 10

20 : x

20/50 = x/10

x = 4ml
