TAE Functions in the Surgical Area

• Cleaning of instruments, equipment, and surfaces according to protocol.
• Sending instruments to central sterilization (clean, dry, and in proper containers).
• Receiving instruments and textile equipment from central sterilization, verifying and controlling sealed sterilization containers (color indicator).
• Picking up disposables and discarding them in special containers.
• Replacing materials.
• Receiving the patient in the pre-operative area, identifying them, and reviewing their clinical history.
• Checking patient's hygiene and shaved areas.
• Providing psychological support.
• Transferring the patient to the recovery unit upon awakening and collaborating with the medical team.

Hominization: The Path to Humanity

Hominization is the process through which primates, our ancestors, gradually acquired the physical structure of humans. This involved a series of morphological changes affecting their bodies, changes observed in the fossil record. Significant morphological changes include:

• Lengthening of the hip.
• Development of bipedal walking legs.
• Atrophy of the lower jaw and masseter muscles (releasing the skull).
• Increasing complexity of the brain (leading to greater intelligence).
• Development of the hand, particularly the thumb (allowing the use and manufacture of tools).

Humanization is the process by which our ancestors acquired culture, the elements that constitute civilization. This involves not physical changes, but cultural... Continue reading "Hominization and Evolution: Key Concepts Explained" »

Procedure: Inform the patient that it is bath time and request their cooperation. Offer the bedpan or urinal before you start cleaning. Gather all materials so that they are within reach. Wash your hands and put on gloves. Place the patient in a supine position.

1. Head - Hair and Face

Hair

From the recumbent position, remove the patient's pillow and place a towel under their head. Roll another towel around the neck. Place a waterproof sheet under the patient's head and shoulders, securing the towel and a rubber grip. Create a channel with the sheet leading to a container or basin to collect water. Protect the patient's eyes with a washcloth. Wet the hair and apply shampoo. Scrub, making circular motions to massage the scalp gently with your fingertips.

Tumor Diseases and Cancer

In normal tissues, cells divide to produce new cells that replace those that are old or damaged. These old or damaged cells must die to make room for new ones. When this balance is altered, a tumor appears (a disorganized mass of tissue). Most tumors are benign.

Malignant Tumors: Cancer

A malignant tumor is one whose cells can move from the initial tumor site to build new tumors in other parts of the body. Malignant tumor cells have two key characteristics:

• Invasiveness: The ability to penetrate and spread through adjacent tissues.
• Metastasis: The ability to penetrate into lymphatic and blood vessels, move through the blood and lymph, and settle in any part of the body to form a secondary tumor.

Organic and Physiological Changes

Organic and physiological changes: Functional modifications occur in the oral cavity and gastrointestinal tract. These include a decline in salivary secretion, reduced esophageal peristalsis, and decreased gastric acid secretion. Sensory alterations affect sight, taste, and smell, leading to inappetence and disinterest in food, often resulting in malnutrition.

Metabolic Changes

Metabolic changes: Cholesterol levels change, generally increasing lipemia, and protein synthesis degrades. Glycemic alterations in glucose utilization are frequent, leading to a decline in basal metabolism and, consequently, reduced energy needs.

Physical Activity

Physical activity: Physical work effectiveness and aerobic capacity (maximal... Continue reading "Nutrition for Seniors: Maintaining Health and Well-being" »

Domestic Plumbing Systems: Wastewater Management

Plumbing in domestic construction is designed to collect wastewater (including soapy water, greywater, and sewage) generated in bathrooms, powder rooms, laundry areas, and kitchens. This wastewater is then efficiently conducted through a network of pipes, drainpipes, and sewer lines, eventually connecting to municipal sewage networks.

In some rural areas where municipal sewage networks are unavailable, septic tanks are utilized for wastewater treatment. For specific situations or certain water features, latrines may also be employed.

Key Components of a Domestic Plumbing Installation

• Rainwater Downspouts
• Wastewater Drainage Pipes
• Strainers
• Drain Traps (e.g., P-traps, S-traps)
• Hydraulic Seals
• Secondary

Skin Preparation Prior to Surgery: Surgical Field Objectives

To facilitate involvement and prevent infection.

Steps:

1. Prepare and inform the patient about the materials.
2. Accommodate and expose the area, protecting it with a towel.
3. Prepare bed linens.
4. Inspect the area to be shaved.
5. Cut long hair with an electric razor and discard it.

Wet Preparation:

• Lather the area with wet gauze soaked with antiseptic soap.
• Shave the skin, stretching it without causing abrasions.
• Wash the area with antibacterial soap and dry thoroughly.

Dry Preparation:

• Shave the skin, stretching it without causing abrasions.
• Wash the area with antiseptic soap and dry thoroughly.

6. Collect the swab, ensuring no hairs remain on the bed.
7. Dispose of the razor in the appropriate container.
8. Notify

Toxicological Properties and Exposure

The dose of a poison refers to the quantity absorbed by the body, typically measured in milligrams per kilogram (mg/kg). The resulting damage depends on various factors, including human physiology, the contaminant's inherent toxicity, and the rate at which the body absorbs the contaminant. Given the variability of these factors, we define the concept of exposure, represented by the formula E = f(c, t), where 'c' is concentration and 't' is time.

Types of Poisoning

• Acute Intoxication: This leads to a severe deterioration in the body, becoming apparent within a short period. It requires acute exposure to the toxic substance and rapid absorption by the organism.
• Subacute Intoxication: Less severe than acute intoxication,

1. Basic Emotions

• Joy
• Interest
• Excitement
• Surprise
• Sadness
• Anger
• Disgust
• Contempt
• Fear
• Shame
• Guilt

2. Physiological Responses to Emotions

Emotions trigger physical changes such as an accelerated heart rate, muscle tension, stomach tingling, and dry mouth. These responses provide energy by sending more blood sugar to the liver. Increased oxygen demand leads to a higher heart rate. Digestion slows down as blood is redirected to muscles. Pupils dilate to allow more light, and perspiration increases to cool the body.

3. Detecting Emotions and Lies

While it's difficult to detect lies definitively, physiological responses can indicate emotions. Changes in breathing, pulse pressure, blood flow, and perspiration accompany emotional states.
