Blood Groups and Antigens

Red blood cells carry antigens (proteins) on their surface. Depending on which antigens are present, the blood belongs to a specific group, and the plasma contains antibodies against the antigens that are absent.

• Group A: has A antigens and anti-B antibodies.
• Group B: has B antigens and anti-A antibodies.
• Group AB: has A and B antigens and no antibodies against them.
• Group O: has no A or B antigens and has both anti-A and anti-B antibodies.

The agglutination reaction occurs when an antibody meets its matching antigen, causing red blood cells to clump together.

Rh Factor

Some people have a protein called the Rh factor on their red blood cells:

• Rh positive (Rh+): the protein is present.
• Rh negative (Rh-): the protein is absent.

Psychomotricity: Psychological and Motor Relationships

Psychomotricity is the relationship between two elements: psychological and motor. Understanding psychomotricity means studying the set of phenomena related to body movement and the capacities that allow an individual to develop their capture and participation in the environment.

Psychomotricity in School

Teachers work with different norms, which depend on the evolution that each child has had during their developmental periods. Current trends attribute an active role to the child's experiences and to the assimilation process of the child.

Psychomotricity in School: What the School Should Know

Starting Point: The Child's Experience

The child's activity is not passive. The child is intervening,... Continue reading "Psychomotricity: Key Concepts, Body Schema and Relaxation in School Education" »

1. Intelligence in Psychology

Intelligence is one of the first objects of study in psychology. Its definition and complexity are still debated, and it remains a multidisciplinary research topic.

Classic Theories

• Galton applied innate methodology and statistics to intelligence.
• Spearman proposed a two-factor theory and used factor analysis. He identified a general factor (g) and specific abilities.
• Thurstone identified seven primary mental abilities: verbal comprehension, verbal fluency, numerical ability, memory, perceptual speed, spatial visualization and inductive reasoning.
• Guilford proposed a three-dimensional model of intelligence: operations (mental processes), contents (types of information) and products (the form the information takes). He

Training Principles for Sports Performance

Basic training principles of sports activity

The general and special preparation principle

The principle of progressive and gradual load increment

The principle of wave-like load variations

The principle of continuity in the training process

The cyclic character principle of the training process

The principle of the level of direction of sports achievements towards higher levels

Superior achievements.

Among the most important measures for the gradual progression of load are:

• Increase in training frequency
• Increase in training volume
• Increase in training intensity

Regarding the wave-like load variation principle, there are three types:

Medium loads, lower loads, and high loads.

In the beginning of the training process,... Continue reading "Training Principles for Sports Performance: Progressive Load and Specialization" »

Wrist and Hand Anatomy

Wrist: The carpus consists of 8 bones divided into 2 rows. The first row includes the scaphoid, lunate, triquetrum and pisiform. The second row includes the trapezium, trapezoid, capitate and hamate.

Hand: The hand uses 2 types of bones: the metacarpals and the phalanges.

• Metacarpals: Long bones with a curved shape, numbered 1 to 5 from the thumb side to the little finger side.
• Phalanges: Long bones. There are 3 in each finger, except the thumb, which has 2 (proximal and distal).

Joints

Radiocarpal joint: The principal joint of the wrist is the radiocarpal joint, a monocondylar joint formed between the radius and the first row of carpal bones. It allows flexion (about 85–90°), extension, abduction (about 15°) and adduction

Renaissance (XV-XVI Centuries)

Renaissance: Vesalius performed dissections on cadavers and published De corporis fabrica libri septem. Pare, a French surgeon, advised stump massage and treated atrophied muscles and retractions. Mendez Cristobal wrote a book on therapeutic exercise. Subsequent publications highlighted the benefits of different types of exercise, including passive exercise for paralyzed patients. Savonarola wrote on balneotherapy in De Balneis et Thermis. Pietro Vergerio advocated physical education programs for young nobles, emphasizing mental and physical education, including hydrothermal therapy such as swimming. William Gilbert studied magnetism and electricity in De Magnete.

Hospital Center for Patients with Chronic Illness and Elderly Care

Situations that surpass the capacities of primary health care services.

Admission Services

In the hospital, attention is dedicated to administrative barriers of admissions and high follow-up.

Regular Admission Steps

• 1st: Greet, review, and present.
• 2nd: Ensure it is the correct room.
• 3rd: Accompany the patient.
• 4th: Present the companion.
• 5th: Explain the call bell and its use.
• 6th: Clarify regarding personal objects.
• 7th: Offer help if needed.
• 8th: Provide information about their rights, norms of the center, organizational dependency, hospital service, what they can use, and the hospital safe.
• 9th: Ask about their customs and needs to adapt care to their illness.
• 10th: Inform that someone

Sensation and Sensory Receptors

Simply put, sensations are basic experiences related, from a physiological point of view, to the activity of sensory receptors that allow us to experience or capture stimuli from both the external and internal environment (Goldstein, 1988). Sensation refers, therefore, to the mere reception of experiential information or the interplay we experience through the senses prior to a stimulus (Goldstein, 1988).

Types of Sensations

• Exteroceptive sensitivity: Captures stimuli from the outside world and the external qualities of one's own body.
• Interoceptive sensitivity: Provides information from the internal environment of the body, reflecting the state of organs and visceral functions (hunger, anxiety, physiological needs,

Motor Response

The locomotor apparatus is the system that carries out movement. It is composed of two elements: the skeleton (passive elements, bones) and the muscles (active elements).

Types of Skeletons

• Hydrostatic skeletons: fluid maintained under pressure, found in cnidarians and worms.
• Exoskeletons: made of chitin in arthropods, and shells in molluscs.
• Endoskeletons: found in sponges (spicules) and in vertebrates (bones).

Bone Tissue

Bones are formed by organic substances (ossein, which gives elasticity) and mineral substances (phosphate and calcium carbonate, which give resistance).

Classification of Bones

According to their shape, bones are classified as:

• Long bones: made of an epiphysis, a medullary cavity, a shaft, marrow, and a surrounding

Cardiovascular and Vascular Pathologies: Nursing Care

Shock

Definition and Etiology: Shock is a critical condition characterized by cellular hypoxia and energy failure due to an imbalance between oxygen supply and demand. It can appear acutely or insidiously. The body attempts to survive through homeostatic mechanisms to restore tissue perfusion. Etiologies include hypovolemia, cardiogenic pump failure, and maldistribution (neurogenic, spinal, and septic). Alterations in cellular oxygen uptake also occur, particularly in septic shock.

Stages of Shock

• 1. Level 1 (Mild/Compensated): Cellular changes detected clinically as normal blood pressure (BP) within normal limits, normal heart rate (HR), respiratory rate (RR), skin tone, and preserved consciousness.
