There are several factors that can contribute to the effect an environmental toxin has on the human body. They are:

- Form and innate chemical activity

- Dosage, especially dose-time relationship

- Exposure route

- Species

- Life stage, such as infant, young adult, or elderly adult

- Gender

- Ability to be absorbed

- Metabolism

- Distribution within the body

- Excretion

- Health of the individual, including organ function and pregnancy, which involves physiological changes that could influence toxicity

- Nutritional status

- Presence of other chemicals

A 75-year-old client is admitted to the hospital with lower gastrointestinal bleeding. the client's hemoglobin on admission to the emergency department is 7.3 g/dl. the health care provider prescribes two units of packed red blood cells (rbcs) to infuse over one hour each. each unit of packed rbcs contains 250 ml. the blood administration set has a drip factor of 10 gtt/ml. what is the flow rate in drops per minute? record your answer using a whole number.

Answers

For the answer to the question above,

let's say Each unit of packed red blood cells contains 250 ml. Each unit is to infuse over 1 hour (60 minutes).

Use the following equation:
250 ml/60 minutes = 4.16 ml.
Multiply by the drip factor:
4.16 ml × 10 gtt = 41.6 gtt/minute (42 gtt/minute).

During normal cell division, a parent cell having four chromosomes in G1 will produce two daughter cells, each containing ______.

Answers

When a parent cell splits into two daughter cells, it is mitotic cell division (Mitosis). So if the parent has four chromosomes and the daughter cells are identical, they will also each have four chromosomes. For example, we humans have 46 chromosomes, 26 of them from the mom and the dad.

Rigor mortis typically disappears after how many hours?

Answers

The answer is 8-12 hours.

Rigor mortis is caused by chemical reactions in muscles after death. Usually, parts of the body become stiffened because ATP is lost after death. After death oxygen concentration in the body decreases because ATP is still being produced and respiration is stopped. When there is no oxygen, anaerobic glycolysis produces ATP using glycogen. When glycogen is depleted, ATP production stops, and rigor mortis begins 2 hours after death. ATP is required during muscle respiration, but now there is a limited concentration of ATP, and its production is stopped. So, muscles could not be relaxed. 8-12 hours after death, muscle fibers are decomposed by enzymes or bacteria, and body relaxes, exiting rigor mortis.

Answer: The answer is not 8-12 hours

Explanation:

That 8-12 hours is for Liver Mortis.
