Emerging Diseases Defined

An emerging disease is a disease that appears at specific times and places and has become a new epidemic. Examples include:

• Acquired Immune Deficiency Syndrome (AIDS): A disease affecting humans infected by HIV.
• Bird Flu (Avian Influenza): A disease caused by a virus primarily affecting birds, which can be transmitted to humans through contact with infected birds or their environment.
• Severe Acute Respiratory Syndrome (SARS): A form of pneumonia that first appeared in 2002 in China and subsequently spread to other countries.

Re-emerging Diseases Explained

Re-emerging diseases are infectious diseases from the past that had been significantly reduced but have re-emerged, often with increased incidence or geographic spread.... Continue reading "Key Health Concepts: Diseases, Diagnostics, and Wellness Strategies" »

Preventing the Transmission of Infectious Diseases

The objective of aims involved in the second link in the chain is to prevent the transmission of infectious diseases.

Isolation

Isolation consists of separating the source of infection in places and conditions that prevent direct or indirect diffusion of the agent by preventing their passage into the healthy or ill, susceptible patients, to interpose barriers to prevent clubs.

Purpose of Isolation

• Separating contagious people so they do not pass the disease to healthy people. (Common barrier or barrier isolation technique)
• Separating patients that have diminished defenses to protect them from the possibility of acquiring a communicable disease. (Reverse, protective, or barrier isolation technique)

The Miracle of Fetal Development

The journey from conception to birth is an extraordinary process of growth and transformation. The developing fetus recognizes various actions and sensations, including dreaming.

Conception and Early Stages

• Fertilization: Sperm possess a unique 'smell' that guides them to the egg. The fusion of the sperm and egg nuclei marks fertilization.
• Implantation: The fertilized egg then travels to the mother's uterus and implants in the placenta.
• Trimesters: Pregnancy is typically divided into three trimesters, each marking significant developmental phases.

Week 2-3: Initial Transformations

• 15 Days Post-Implantation: Around 15 days after implantation, the embryo undergoes a significant transformation,

Effective Secretion Removal Techniques

Our bodies naturally produce fluid secretions in minimal quantities that usually don't obstruct the airway. The cough reflex typically eliminates any excess. However, sometimes we are unable to remove secretions due to excessive production or thickening, or an inability to cough effectively. This can occur in pathologies such as chronic respiratory conditions, in immobilized patients, postoperative patients, and patients with neuromuscular problems.

Measures to Eliminate Secretions

Hydration

Adequate hydration helps to make secretions more fluid, facilitating their expulsion.

Chest Physiotherapy

Chest physiotherapy involves various procedures, including:

• Breathing Exercises: Perform breathing exercises several

Clinical History

Includes information on family history: certain hereditary diseases may affect the course and outcome of pregnancy. Personal history: the doctor provides health status information from earlier in the pregnancy. Obstetrical history: it is relevant if the mother is multiparous, including previous pregnancies, birth weights of children, duration of labor, and any complications during labor or postpartum. All this information must be recorded in the pregnant woman's health record.

Physical Examination

Investigates changes requiring attention, such as dental caries, dietary deficiencies, and weight fluctuations. Weight and blood pressure are measured and recorded in the history to monitor for any significant changes.

Fundamentals of Drug Treatment and Pharmacology

What Are Drugs?

Drugs are products used to cure, alleviate, prevent, or diagnose disease. Medicines contain one or more active principles (APIs)—substances that give the drugs their therapeutic properties.

Adverse Reactions and Drug Safety

All medicines can cause Adverse Reactions, which are negative effects of the drugs. In order to market a drug, health authorities must ensure that its benefits significantly outweigh any possible adverse reactions.

Dosing, Efficacy, and Drug Interactions

Each drug has an optimal dose. Increasing the dose does not necessarily increase benefits; however, it often increases the risk of adverse reactions.

There are drugs that interfere with each other if given together.... Continue reading "Pharmacology Basics: Receptors, Dosing, and Drug Marketability" »

Therapeutic Actions of Drugs

• Palliative
• Curative
• Supportive (De sostén)
• Substitutive
• Chemotherapeutic
• Restorative (Repair)

Factors Affecting Drug Action

• Development
• Gender-related factors
• Culture, Ethnicity, Genetics
• Diet

The Five Rights of Medication Administration

Ensuring patient safety requires adherence to the following principles:

1. Right Patient
2. Right Time
3. Right Medicine
4. Right Dose
5. Right Route of Administration

The Four 'I's Rule for Nurses

This rule emphasizes accountability in medication processes:

• I Prepare (Yo preparo)
• I Administer (Yo administro)
• I Record (Yo registro)
• I Respond (Yo respondo)

Drug Administration Routes Classification

• Enteral (Natural)
• Parenteral (Artificial)
• Topical (Natural)
