What should you do if you are exposed to potentially infectious materials?

What should you do if you are exposed to potentially infectious materials?

Wash exposed skin, cuts, and needlestick injuries thoroughly with soap and water. If you have been splashed by potentially infectious fluids around the eyes, nose or mouth, flush the area with water. Immediately report the incident to emergency medical services.

What should you do if you are involved in an exposure incident?

1. Provide immediate care to the exposure site.

1. Wash wounds and skin with soap and water.
2. Flush mucous membranes with water.
3. DO NOT USE instrument involved on patient!
4. Employee must report incident immediately to supervisor/employer.

What to do if u get pricked by a needle?

Treatment: When somebody accidentally gets pricked by a needle: as soon as possible, wash the area around the puncture for at least 30 seconds, using soap and warm water. Bottled water can also be used if no hand washing facilities are available.

What is the first thing you should do if you are exposed to blood or body fluid?

Wash your hands immediately after any exposure to blood or body fluids, even if you wear gloves. If you get splashed in the eyes, nose, or mouth, flush with water. If you are pricked by a needle (needlestick), contact your doctor right away for further advice.

Which body fluid is not potentially infectious?

Feces, nasal secretions, saliva, sputum, sweat, tears, urine, and vomitus are not considered potentially infectious unless they are visibly bloody.

What diseases are carried in body fluids?

Examples of diseases spread through blood or other body fluids:

• hepatitis B – blood, saliva, semen and vaginal fluids.
• hepatitis C – blood.
• human immunodeficiency virus (HIV) infection – blood, semen and vaginal fluids, breastmilk.
• cytomegalovirus (CMV) infection – saliva, semen and vaginal fluids, urine, etc.

Where is most of the fluid in the body found?

Extracellular fluid, in biology, body fluid that is not contained in cells. It is found in blood, in lymph, in body cavities lined with serous (moisture-exuding) membrane, in the cavities and channels of the brain and spinal cord, and in muscular and other body tissues.

Does total body water increase with age?

Total body water manifests a linear decrease with aging, until it constitutes less than 50% of body weight in very old individuals. There is thus a mean decrease of 0.3 liter in total body water during the period of life from adulthood to old age. This loss seems then to increase even later after 70 years.

Which represents the largest fluid compartment in the body?

intracellular fluid compartment

How many fluids does the body have?

By learning a bit more about 11 of these body fluids, we can develop a deeper appreciation for the beauty and complexity of our own biology. What exactly are these fluids, and what often unheralded contributions do they make?

What is the role of fluid in the body?

Fluid helps your body to digest (break down) food. Fluid helps to prevent constipation by keeping stools soft and regular. Fluid is an important part of blood, and helps to carry nutrients around the body.

What is the main component of all body fluids?

The extracellular fluid is mainly cations and anions. Plasma is mostly water and dissolved proteins, but also contains metabolic blood gasses, hormones, and glucose. The composition of transcellular fluid varies, but some of its main electrolytes include sodium ions, chloride ions, and bicarbonate ions.

Which body fluid is most infectious?

Potentially infectious blood and body fluids include

• fluids containing visible blood.
• semen.
• vaginal secretions.
• cerebrospinal fluid.
• synovial fluid, pleural fluid.
• peritoneal fluid.
• pericardial fluid.
• amniotic fluid.

What is the most potent stimulus of the thirst mechanism?

Subtle changes in plasma osmolality are the most potent stimulus for thirst. In response to increases in osmolality, osmoreceptors activate release of the neurohormone vasopressin (also known as antidiuretic hormone). The released vasopressin acts on the kidneys to conserve water to correct the hyperosmolar state.

What leads to respiratory acidosis?

Respiratory acidosis involves a decrease in respiratory rate and/or volume (hypoventilation). Common causes include impaired respiratory drive (eg, due to toxins, CNS disease), and airflow obstruction (eg, due to asthma, COPD [chronic obstructive pulmonary disease], sleep apnea, airway edema).

What is the most common route for water loss?

The major route of intake of water is by ingestion of fluids and food. Food contains water, and additional water is produced during oxidation of carbohydrates. The major routes of water loss are urine, feces, sweat and insensible water loss by evaporation from the respiratory tract and diffusion through the skin [1].

Which of the following is a stimulus for thirst?

Hormonal stimuli for thirst (A) The most potent hormonal stimulus for thirst is angiotensin II (AngII), which is generated when the rate-limiting enzyme renin is secreted by the kidneys in response to hypovolemia or hypotension.

What hormones make you thirsty?

Thirst isn’t the brain’s only response to dehydration. When the body gets low on water, the hypothalamus increases the synthesis of an antidiuretic hormone called vasopressin, which is secreted by the pituitary gland and travels to the kidneys.

Does ADH stimulate thirst?

If blood osmolality increases above its ideal value, the hypothalamus transmits signals that result in a conscious awareness of thirst. The person should (and normally does) respond by drinking water. The hypothalamus of a dehydrated person also releases antidiuretic hormone (ADH) through the posterior pituitary gland.

What are the two types of thirst?

Prior research has shown that our brains process at least two main kinds of thirst: Osmotic and hypovolaemic. Osmotic thirst is what we feel when we need more water. Hypovolaemic thirst is what we feel when we need minerals and water to replenish blood supplies.
