Fundamentals of Nursing Test 2: A Comprehensive Review

This article serves as a comprehensive review for Fundamentals of Nursing Test 2, covering key concepts typically included in such an exam. We'll delve into crucial areas, providing explanations and examples to solidify your understanding. Whether you're a student preparing for your exam or a nursing professional looking to refresh your knowledge, this guide will be a valuable resource. This review covers a wide range of topics, including infection control, wound care, vital signs, medication administration, and basic patient care. Mastering these fundamentals is crucial for safe and effective nursing practice.

I. Infection Control: The First Line of Defense

Infection control is paramount in nursing. Understanding the chain of infection and implementing appropriate measures is vital to prevent the spread of pathogens.

A. The Chain of Infection: Breaking the Cycle

The chain of infection consists of six links:

1. Infectious Agent: The pathogen (bacteria, virus, fungus, etc.) causing the infection.
2. Reservoir: Where the pathogen lives and multiplies (human, animal, environment).
3. Portal of Exit: How the pathogen leaves the reservoir (e.g., respiratory droplets, blood, feces).
4. Mode of Transmission: How the pathogen travels from reservoir to host (e.g., direct contact, airborne, vector-borne).
5. Portal of Entry: How the pathogen enters the host (e.g., mucous membranes, broken skin).
6. Susceptible Host: An individual at risk of infection due to weakened immunity or other factors.

Breaking any link in this chain can prevent infection. This is achieved through various infection control practices.

B. Standard Precautions: Universal Application

Standard precautions are the foundation of infection control. They apply to all patients, regardless of their infection status. Key elements include:

• Hand hygiene: The single most important action to prevent infection. Use soap and water or an alcohol-based hand rub.
• Personal protective equipment (PPE): Use gloves, gowns, masks, eye protection, and face shields as appropriate to the situation and potential exposure.
• Safe injection practices: Use sterile needles and syringes, and dispose of them properly.
• Respiratory hygiene/cough etiquette: Cover coughs and sneezes, and use tissues to dispose of respiratory secretions.
• Environmental cleaning and disinfection: Maintain a clean and disinfected environment.

C. Transmission-Based Precautions: Targeted Strategies

Transmission-based precautions are implemented in addition to standard precautions when a patient is known or suspected to have a specific infectious agent. These precautions are categorized as:

• Airborne: For infections spread through the air (e.g., tuberculosis, measles). Requires a negative-pressure room and N95 respirator.
• Droplet: For infections spread through large respiratory droplets (e.g., influenza, pneumonia). Requires a private room and surgical mask.
• Contact: For infections spread through direct or indirect contact (e.g., MRSA, C. difficile). Requires a private room, gloves, and gown.

II. Wound Care: Promoting Healing

Wound care is a critical nursing skill. Proper assessment, cleaning, and dressing are essential to promote healing and prevent complications.

A. Wound Assessment: A Systematic Approach

A thorough wound assessment includes:

• Location: Precise location on the body.
• Size: Length, width, and depth.
• Appearance: Color, texture, presence of exudate (drainage), and surrounding skin condition.
• Pain: Assess the patient's pain level using a standardized pain scale.
• Odor: Note any unusual odor.

B. Wound Cleaning and Dressing: Techniques and Principles

Wound cleaning aims to remove debris and pathogens, promoting healing. Appropriate techniques depend on the wound type. Common methods include:

• Irrigation: Using sterile saline or other solutions to flush the wound.
• Debridement: Removal of dead or necrotic tissue to promote healing. This can be done surgically or using non-surgical methods.

Wound dressings protect the wound, absorb drainage, and provide a moist environment for healing. The choice of dressing depends on the wound type and its characteristics.

III. Vital Signs: Monitoring the Body's Status

Accurate measurement and interpretation of vital signs are fundamental to nursing practice. Vital signs include:

• Temperature: Reflects the body's heat balance. Normal range is approximately 97.8°F to 99.1°F (36.5°C to 37.3°C).
• Pulse: Reflects the heart rate. Normal range for adults is 60 to 100 beats per minute (bpm).
• Respirations: Reflects the breathing rate. Normal range for adults is 12 to 20 breaths per minute (bpm).
• Blood pressure: Reflects the pressure of blood against artery walls. Normal range for adults is typically less than 120/80 mmHg.
• Oxygen saturation (SpO2): Measures the percentage of hemoglobin saturated with oxygen. Normal range is typically 95% to 100%.

IV. Medication Administration: Safety First

Safe and accurate medication administration is a cornerstone of nursing. This involves:

• The "Five Rights" and Beyond: The five rights of medication administration (right patient, right drug, right dose, right route, right time) are essential, but additional rights, such as right documentation and right to refuse, are also crucial.
• Medication Calculations: Accurate calculation of medication doses is critical to prevent medication errors.
• Different Routes of Administration: Understanding the different routes of administration (oral, intravenous, intramuscular, subcutaneous, etc.) and their implications is essential.
• Monitoring for Adverse Effects: Careful observation for adverse effects and timely reporting are crucial aspects of safe medication administration.

V. Basic Patient Care: Holistic Approach

Basic patient care encompasses a wide range of activities aimed at promoting patient comfort, safety, and well-being. This includes:

• Hygiene: Assisting patients with bathing, oral care, and grooming.
• Nutrition: Assisting with feeding, monitoring intake and output, and providing nutritional support.
• Elimination: Assisting with toileting and managing bowel and bladder function.
• Mobility: Assisting with ambulation, transferring, and range-of-motion exercises.
• Pain Management: Assessing pain, administering analgesics, and implementing non-pharmacological pain relief methods.
• Positioning: Using proper body mechanics to prevent injury to both the patient and the nurse.
• Communication: Effective communication is essential for building rapport and understanding the patient's needs.

VI. Legal and Ethical Considerations

Nursing practice is governed by legal and ethical principles. Understanding these principles is crucial for safe and responsible practice.

• Patient Rights: Respecting patient autonomy, privacy, and dignity is paramount.
• Informed Consent: Ensuring patients understand the risks and benefits of procedures and treatments before providing consent.
• Confidentiality: Protecting patient information and maintaining confidentiality.
• Professional Boundaries: Maintaining professional relationships with patients and avoiding boundary violations.
• Documentation: Accurate and timely documentation is critical for legal and ethical reasons.
