Clostridium difficile is a gram-positive, endospore forming anaerobe. Is endotoxin part of its virulence factor toolkit?.

No, endotoxin is associated with LPS, and <em>C. difficile</em> does not have LPS.

<h3>What are the endotoxins produced by <em>Clostridium difficile</em>?</h3>

A bacillus that produces toxins and forms spores, <em>Clostridium difficile</em> is Gram-positive and anaerobic. Once it enters the human intestine, <em>C. difficile </em>can transform into the disease-causing, vegetative condition. The presence of glycine and cholate derivatives makes this anaerobic bacterium well suited to the anaerobic environment of the colon, and it also makes <em>C. difficile</em> spore germination easier.

Toxin A (TcdA) and toxin B (TcdB) are the major endotoxins that regulate<em> Clostridium difficile's</em> pathogenicity. Target cells are largely affected by these toxins' disruption of their cytoskeletal framework and tight junctions, which results in rounding of the cell and eventual cell death. A fulminant illness is closely linked to detectable <em>C. difficile</em> toxemia. The development of <em>C. difficile</em> strains with toxin A and B gene mutations suggests that toxin B plays a significant role in the pathogenesis of CDI as a whole.

I understand the question you are looking for is this:

Clostridium difficile is a Gram-positive, endospore forming anaerobe. Is endotoxin part of its virulence factor toolkit?

a. yes, it produces several toxins.

b. no, endotoxin is associated with flagella, and <em>C. difficile</em> does not have flagella.

c. no, endotoxin is associated with teichoic acids, and <em>C. difficile </em>does not have teichoic acids.

d. no, endotoxin is associated with LPS, and <em>C. difficile</em> does not have LPS

Heinz bodies, which may result in hemolytic anemia, can be formed by the following changes to hemoglobin EXCEPT?
s2008m [1.1K]

Answer:

C) substitutions that reduce the affinity of hemoglobin for oxygen

Explanation:

Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.

The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.

OLga [1]

Shotguns are the most likely source of this wound pattern.

<h3>What is a patient assessment composed of?</h3>

Through observation, the measurement of vital signs, and self-reported symptoms, a comprehensive health assessment provides nurses with knowledge about a patient's physical condition. It includes a thorough physical examination, a general survey, and a medical history.

<h3>What are the four steps in assessing a patient?</h3>

emergency call; assessing scene safety; adopting BSI measures; documenting the mechanism of injury or patient's sickness; figuring out the number of patients; and evaluating what, if any, extra services, such as Advanced Life Support, are required.

<h3>What function does patient assessment serve?</h3>

Nurses may objectively identify each patient's specific requirements and concerns through assessments, as well as any potential treatment barriers that might effect compliance and results.

Just how far should an employee go with loyalty? Are there boundaries?
NeX [460]

Answer:

Ethically speaking, a worker should develop absolute loyalty to a company, or place, he/she works for, as it shows an adaptation and acceptance of the company´s values, principles, and fundamental aspects. This loyalty will ensure that a worker will carry out his/her duty to the best of her/his ability, always in the best interest of the company at large.

However, I do believe there must be a boundary to how much loyalty a person has towards a company, and especially, when this loyalty is pushing the person to perform an activity that basically undermines that person´s own personal values and principles. So, there should be a boundary when the loyalty to a company crosses the line and overcomes the personal limitations, the concience, if you will, of a worker.

For example, if you are a nurse, and the hospital you work for asks you to hide certain information from adverse events that have taken place due to a possible malpractice, or due to institutional shortcomings, but you know that the right thing to do is to hand over such information, for the greater good of patients and their families, over the welfare of the hospital itself, then I believe that the nurse should take the necessary measures, and overcome her loyalty. This event goes over personal boundaries and surpasses any possible loyalty that a worker may be required to have.
