A randomly selected individual is assessed using the GALS procedure and this results in a positive diagnosis, that is the patient is believed to have rheumatoid arthritis. Given the positive result, what is the probability that patient actually has rheumatoid arthritis?

Answers

Answer 1

The probability that the patient actually has rheumatoid arthritis can be determined through Bayes' Theorem.

Bayes' Theorem is a statistical technique that enables researchers to determine the likelihood of an event occurring based on the known or estimated probability of related events occurring. Bayes' theorem formula can be written as: P(A|B) = (P(B|A)P(A))/P(B)Where,P(A|B) denotes the probability of A happening given that B has already happened.P(B|A) denotes the probability of B happening given that A has already happened.P(A) denotes the probability of A happening.P(B) denotes the probability of B happening.

In this case, we are trying to determine the probability of a patient having rheumatoid arthritis given that the GALS procedure has resulted in a positive diagnosis, that is, P(RA|Pos). Using Bayes' Theorem, we can write:P(RA|Pos) = (P(Pos|RA)P(RA))/P(Pos)where, P(Pos|RA) denotes the probability of a positive diagnosis given that the patient actually has rheumatoid arthritis.P(RA) denotes the probability of a randomly selected individual having rheumatoid arthritis.P(Pos) denotes the probability of a positive diagnosis.

The values of P(Pos|RA), P(RA) and P(Pos) must be determined based on the available data or estimates. Once these values have been determined, we can calculate the value of P(RA|Pos) and answer the question.

Which may occur if a client experiences compartment syndrome in an upper extremity?

a) Subluxation
b) Callus
c) Whiplash injury
d) Volkmann's contracture

Answers

Volkmann's contracture may occur if a client experiences compartment syndrome in an upper extremity.

Compartment syndrome is a serious condition that develops when there is swelling in the compartment which eventually results in increased pressure. It can be a medical emergency and can lead to permanent damage to the muscles, nerves, and blood vessels. Compartment syndrome can occur in any part of the body that has muscles and can occur due to fractures, bruises, or any injury to the affected area. Some of the common areas that are susceptible to compartment syndrome are the arms, legs, and abdomen.

Volkmann's contracture is a complication that can arise from compartment syndrome. It is the permanent contracture of the fingers, hand, and wrist muscles and occurs due to reduced blood supply and permanent damage to the muscles due to compartment syndrome. In simple words, when there is a lack of blood supply to the muscles, they become necrotic and are eventually replaced with scar tissue. This causes a reduction in the size and mobility of the affected muscles, which results in the permanent shortening of the affected muscles leading to Volkmann's contracture.
