Answer:
Alexandra is experiencing <u>acute </u>pain.
Explanation:
Acute pain is a type of pain that is generally related to the damaged of soft tissue such as the one on Alexandra's big toe, in other words, the skin and muscles of her big toe. Acute pain is sharp and severe, but it goes away in a short time, which can vary from some minutes to some months.
Based on the results of the study shown below, the epidemiologist has reason to worry because the incidence rate increased over four times the previous level as shown below:
- number of HIV cases = 440 persons
- new incidence rate = 2.25 per 1000 persons
<h3>What is prevalence and incidence rate?</h3>
Prevalence rate is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time.
- Prevalence rate = number of cases/total population × 100%
Incidence rate is the proportion of new cases of a condition observed within a given period of time.
- Incidence rate = number of new cases/population at risk × 1000
- population at risk = total population - previous cases
The number of people who had HIV in January 2012 is calculated as follows:
- number of HIV cases = prevalence rate × total population
number of HIV cases = 2.2% × 20000
number of HIV cases = 440 persons
Incidence rate between February 2012 and January 2013 is calculated as follows:
Incidence rate = 50/(20000 - 440) × 1000
Incidence rate = 2.25 per 1000 persons.
Based on the new incidence rate, the epidemiologist has reason to worry because the incidence rate has increased over four times the previous level.

Answer:
Increase
Explanation:
Vasopressin is ADH. ADH is secreted by the hypothalamus and regulates the body's osmolarity. Since Giardia causes a loss of sodium ions, the body's osmolarity is affected. To counteract this and maintain homeostasis, more vasopressin is secreted, thus telling the body to absorb more ions back in the kidneys.
