Theory of development pertaining to the young adult 20-39 years
Havighurst Stages and Tasks (learning is a lifelong task; failure to master a stage could alter development)
Freud’s theory focuses on motivation for behavior and is questionable for relevance in the 21st century. His theories are based on human drives: libido, aggression, and survival. His stages end at adulthood.
Piaget’s theory is that cognitive development requires adaptation, assimilation, and accommodation; draws on logical conclusion starting at adolescence and into adulthood.
Kohlberg’s moral theory expands on Piaget’s theory. Moral development refers to the changes in a person’s thoughts, emotions, and behaviors that influence their beliefs about right and wrong.
Erikson’s theory progresses through eight stages - mostly moving from stage to stage but sometimes regressing
Stage 6 - Intimacy v Isolation (21-40 years)
Choosing social group and romantic partner
Take on more commitments and responsibility
Choose an occupation
Theory of development pertaining to the middle aged adult 40-65 years
piaget This is the formal operations of cognitive development (all of his adult stages)
Able to reflect on past and anticipate future
Memory is intact along with stored knowledge
Slowing of reaction time, speed of performance, and fluid intelligence
Erikson’s stage 7
Generativity vs stagnation
Generativity is the process of guiding the next generation or improving society as a whole.
Stagnation occurs when development ceases: a stagnant middle adult cannot guide the next generation or contribute to society.
Theory of development pertaining to the older adult 65+
Erickson’s stage 8 Integrity vs despair

Discuss variation if age-related physical and cognitive changes in the older adult
Memory Loss of short-term memory is more common than loss of long-term memory; thus, older adults may remember incidents from many years ago but may have trouble recalling what they did earlier in the day.
Physical health problems or medications may affect memory.
An active social life with complete engagement and participation in the community delays memory loss with aging
Regular mental exercises (e.g., crossword puzzles, conversation) appear to stimulate the brain and enhance memory.
Other factors that slow memory loss are getting adequate sleep and rest, eating a nourishing diet, and avoiding drugs and alcohol.

- Depression and loneliness are normal in older adults.
- The older I get, the less sleep I need.
- Older adults can’t learn new things.
- It is inevitable that older people will get dementia.
- Older adults should take it easy and avoid exercise so they don’t get injured.
- If a family member has Alzheimer’s disease, I will have it, too.
- Now that I am older, I will have to give up driving.
- Only women need to worry about osteoporosis.

use critical criteria on how to apply a sterile dressing
-
Gather Necessary Supplies
- Sterile dressing (appropriate size)
- Sterile gloves
- Sterile gauze or cotton balls (if needed for wound cleaning)
- Antiseptic solution (e.g., saline or another appropriate solution)
- Adhesive tape or dressing retention strips (if needed)
- Scissors (if needed)
- Biohazard waste disposal container
-
Perform Hand Hygiene
- Wash your hands thoroughly with soap and water for at least 20 seconds, or use hand sanitizer if soap and water are not available.
-
Prepare the Work Area
- Ensure you have a clean, well-lit area for the procedure. If necessary, clean the surface with an appropriate disinfectant before placing any supplies.
-
Put on Sterile Gloves
- Open the sterile dressing package without touching the inside of the sterile field.
- Carefully put on the sterile gloves, ensuring that you only touch the outside of the glove packaging when removing them, to maintain sterility.
-
Remove the Old Dressing (if applicable)
- If there is an existing dressing, carefully remove it. Use a clean technique, and dispose of the old dressing in a biohazard container. If there is any drainage or exudate, note the amount and appearance for documentation.
- Discard gloves and wash your hands after removing the old dressing.
-
Assess the Wound
- Before applying the new dressing, assess the wound for any signs of infection, such as increased redness, swelling, or pus. If there are concerns, inform the healthcare provider.
- Clean the wound if necessary using sterile saline or another prescribed solution. Use a sterile gauze pad or cotton ball to gently cleanse the wound in a wiping motion from the center outward to prevent contamination.
-
Apply the Sterile Dressing
- Open the sterile dressing package and, without touching the inner portion, place the dressing gently over the wound. Ensure that the sterile side of the dressing is in contact with the wound.
- If the dressing is a gauze pad, ensure it is the appropriate size to cover the wound completely.
- Make sure the dressing is positioned to cover the entire wound and, if necessary, apply additional layers for absorption.
-
Secure the Dressing
- Use adhesive tape or dressing retention strips to secure the dressing in place, ensuring it is snug but not too tight. Be careful not to apply the tape directly to the wound.
- If the dressing is large, you may need additional strips or a secondary dressing to secure the initial one.
-
Dispose of Used Materials
- Discard gloves and any other disposable items into the appropriate biohazard container.
- Clean up the work area and properly dispose of any contaminated materials.
-
Perform Hand Hygiene Again
- Wash your hands thoroughly again after the dressing change to prevent any potential contamination. -
Document the Procedure
- Document the dressing change in the patient’s medical record, including the condition of the wound, the type of dressing used, and any observations (e.g., signs of infection, amount and type of drainage, patient tolerance).
Describe care of wounds with a drain
Penrose Drain – small tube, usually not sutured in place
Hemovac, Jackson-Pratt (JP) drains are suture in and are typically “placed to suction”. This means you compress the device to create suction and facilitate removal of drainage. These are the most common post surgical drains.

Discuss the use of proper body mechanics when providing patient care.
Body mechanics is a term used to describe the way we move our bodies.
Use a wide stance to avoid injury when lifting and to make it easier to maintain balance. With a wide stance the center of gravity is closer to the base of support. With a narrow stance, the body is less stable.
Avoid standing in one position for a long period of time.
Do not lock knees when standing upright.
Do not bend forward at the waist or neck to work in a low position.
Sit with your feet flat on the floor and your knees below hips.
Team Lift
Use resources
Describe types of exercise.
Aerobic Exercise uses large muscle groups and can be maintained continuously. Jogging, aerobics, and brisk walking are aerobic exercises.
Anaerobic Exercise occurs when muscles must obtain energy from metabolic pathways that do not use oxygen. Rapid, intense exercises like sprinting and power lifting are examples of anaerobic exercises.
Isometric Exercise is an exercise in which muscle contraction occurs without motion. It doesn’t require any equipment. Bedbound patients use isometric exercises to gain some strength. For example, asking the patient to press their hand against yours. Planking is an isometric exercise.
Isotonic Exercise involves movement of the joint during muscle contraction. Almost any resistance exercise would be considered an isotonic exercise. For example, weight training or push ups.
Isokinetic Exercise is exercise performed with specialized apparatuses that provide variable resistance to movement. It is a type of strength training. Machines at health clubs and physical therapy departments can be used for this form of exercise.
.Assess for factors affecting mobility and exercise.
Developmental Stage: Older patients may not be as active.
Obesity: leads to health problems and makes movement more difficult.
Chronic Diseases: Inadequate amounts of protein to maintain and build tissue. Muscle wasting and fatigue lead to reduced activity.
Lifestyle: Personal values about exercise and fitness make affect activity level.
Environmental Factors: Weather, neighborhood, finances, and having support system can influence activity.
Plan and implement nursing interventions for patients with alterations inmobility.
Work on energy conservation, building endurance, sleep patterns, ambulation, if possible, coordinated movement, and self initiated body positioning.
If appropriate, teach about medications for pain. Ask if specific movements increase pain, ask about intensity, and frequency of pain.
Promote Exercise – ask about barriers to exercise and discuss ways to overcome those barriers
Teach Stress Relief
Assess caregivers abilities and needs. Assess resources. Assess the home environment. Remember, we are planning our patients discharge needs beginning at admission.
Define NPSG guidelines related to strategies to reduce the risk of infection.
Infection control bundles (also called care bundles) are guidelines for practice that are bundled together in an effort to prevent HAIs such as CAUTIs, CLABSIs, VAPs, and SSIs.
Bundles are used worldwide as a measure to improve client safety and decrease mortality. Although bundles vary from facility to facility, in general a bundle includes a protocol or guideline for how to handle client care to minimize the risk of infection, starting with hand hygiene.
For a bundle to be effective, health care providers and nurses must receive training on how to effectively implement the practices it includes.
Discuss the six links in the chain of infection.
infectious agent
reservoir
portal of exit
mode of transmission
portal of entry
suceptiable host
Describe the stages of a typical infectious process.
Incubation. Infection begins in the stage between successful invasion of the pathogen into the body and the first appearance of symptoms. In this stage, the person does not suspect that they have been infected but may be capable of infecting others. This stage may last only a day, as with the influenza virus, or as long as several months or even years, as with tuberculosis.
Prodrome. The prodromal stage is characterized by the first appearance of vague symptoms. For example, a person infected with a cold virus may experience a mild throat irritation. Not all infections have a prodromal stage.
Illness. The patient becomes ill when the signs and symptoms of the disease appear. If the patient’s immune defenses and medical treatments (if any) are ineffective, this stage can end in death.
Decline. When the patient’s immune defenses, along with any medical therapies, successfully reduce the number of pathogenic microbes. As a result, the signs and symptoms of the infection begin to fade.
Convalescence. Healing begins as the remaining number of microorganisms approaches zero. Convalescence may require only a day or two or, for severe infections, as long as a year or more.
Discuss factors that increase the risk of infection.
Being very young or very old
Breaks in lines of defense
Recuperating from other illness or injury
Tobacco use
Alcohol and other substance abuse
Multiple sexual partners
Environmental factors (working in daycare, living with mold in home, daily exposure to chemicals)
chronic disease
Medications
Poor nutrition
Lack of physical activity
Poor sleep
Stress and grief
Nursing and medical procedures
Compare and contrast standard precautions and transmission-based precautions to prevent spread of infection.
Standard precautions, the first tier of protection, apply to care of all patients. You must assume that every patient is potentially colonized or infected with an organism that could be passed to others in the healthcare setting.
Hand hygiene before and after patient contact for every precaution, every time.
Transmission-based precautions, the second tier of protection, are for patients with known or suspected infection or colonization with pathogens. Recall from the discussion on the chain of infection that pathogens may be transmitted by contact, droplet, or air. Each mode of transmission requires a different approach to prevent infection. These clients will often have supplies specific for their room or require thorough cleaning after use.
Compare and contrast techniques and situations appropriate to medical or surgical asepsis.

Identify safety hazards in the patient environment.
Assess patient for allergies and describe appropriate interventions.
It is the provider’s responsibility to assess, report, and document clients’ allergies and to provide care that avoids exposure.
Allergies should be quickly found on clients’ chart – in Epic is on the left side story board.
Reaction to and/or treatment for allergy should also be in the chart.
Those with severe reactions should educate friends, family, and coworkers about treatment in the event of an allergic reaction.
