Exam 1 Flashcards
Leading Causes of Death
Medical errors and “health care-associated infections”
Medical errors and health care-associated infections each kill more Americans than….
AIDS, breast cancer or vehicle accidents per year
Probability of dying from a health care associated infection or medical error
1 in 760 hospital admissions
The most common way infections are spread
Touching a patient or equipment, then touching another patient without washing your hands.
How infections are spread
- Infectious Agent (germs)
- Source of Infection (human/animal/object)
- Portal of Exit (cough/blood/diarrhea)
- Mode of Transmissions (ex. your hands)
- Portal of Entry (skin/lungs/GI/GU)
- Susceptible Host- Our Patients
Compliance with handwashing by healthcare staff
only 30% to 50%
When to was hands
Entering and leaving patient rooms.
The most important way we can reduce infections
Frequent handwashing
Always use soap and water if
Hands are visibly soiled, presence of infections, before and after eating, after using the restroom, wash hands with friction for at least 20 sec, and after removing gloves and between glove changes.
Bed Safety
Bed in low position, bed wheels locked, lift side rails up x2, and call light in reach
Principle-Based Procedures
- Wash hands before and after care
- Gather supplies
- Introduce self and others
- Identify patient with 2 identifiers
- Explain procedure
- Provide privacy
- Use good body mechanics
- Provide patient safety
Temperature
measurable heat in the body
Pulse
detectable rhythm of the heart contractions
Respirations
frequency of breaths
Blood pressure
pressure of blood in the arteries
Pulse Oximetry
amount of oxygen in the tissues
Vital signs
a means of assessing vital or critical physiological functions
One of the most frequent assessments you will make as a nurse
Why are vial signs checked
Monitor body systems, detect changes in health statues, evaluate effectiveness of interventions, identify life-threatening warning signs
When are vital signs checked
performed no a regular basis
Frequency determined by physician order and/or nursing judgement, client’s condition, facility standards, and location of patient.
Standards for Monitoring Stable patient
every 4-8 hours
Standards for Monitoring Postsurgical patient
every 15-60 minutes
Standards for Monitoring critical/unstable patient
every 5 minutes
Standards for Monitoring home health settings
each visit
Standards for Monitoring clinics
each visit
Standards for Monitoring skilled nursing facilities
weekly to monthly
Interpreting Vital Signs
Compare the patient’s values to normal values then compare with previous values
Temp: under tongue
Oral; most common site
Temp:Ear
Tympanic; adults and children
Temp: Forehead
Temporal; infants/small children
Temp: Armpit
Axillary; healthy newborns
Temp; rectal
Do not use for newborns, patients with low white counts, spinal cord injuries, diarrhea, rectal surgeries, quadriplegics.
Temperature Conversion Fahrenheit to Celsius
F temp minus 32, Multiply by 5, divide by 9
Temperature Conversion Celsius to Fahrenheit
C temp x 9, divide by 5, add 32
Pulse Locations: Apical Pulse
Most accurate site; apex of heart at point of maximal impulse, left midclavicular line, 5th intercostal space, use stethoscope to listen (auscultate), count for 1 minute.
Pulse Locations: Radial Pulse
Most common peripheral site, under thumb on wrist.
Temporal
side of head at temple
Carotid
side of neck below jaw
Brachial
Inner side of elbow
Radial
Thumb-side of inner wrist
Femoral
Bend of leg at groin
Popliteal
Behind knee, inner side
Posterior tibial
Below inner ankle
Dorslis pedis
Top of Foot
Temperature normal range
95.9-99.5 F (35.5-37.5C)
Pulse normal range
60-100 beats per minute
Respirations normal range
12-20 breaths per minute
Pulse Oximetry normal range
> 95% Saturation of peripheral oxygen
Blood pressure normal ranges
Systolic 90-120 mm Hg
Diastolic 60-80mm Hg
mm Hg
millimeters of mercury
Physiology of Blood pressure
Heart beat forces blood against arterial walls, creates a pressure wave as left ventricle contracts and then relaxes, peak phase (highest) Systolic pressure, resting phase (lowest) diastolic pressure.
Stethoscope
Used to auscultate the systolic and diastolic pressure, heard as Korotkoff (thumping) sounds
Sphygmomanometer
Vinyl or cloth cuff, a pressure bulb with regulating valve, and manometer
Hypotension Systolic
Systolic blood pressure <100 mm Hg, some patients normally have low BP, and ask if patient is light-headed or dizzy
Hypotension Orthostatic or postural
A sudden drop in BP, a change position from lying to sitting or standing
Hypertension stats
BP persistently higher than normal, diagnosed when systolic is >140 mmHg or diastolic is >90 mmHg, tested on two or more separate occasions
Hypertension
Primary or Essential Hypertension, diagnosed when there is no known cause for the increase, accounts for about 90% of all hypertension
Hypertension facts
A major cause of illness and death in US, increases stress on heart and blood vessels, severity is directly related to the degree of elevation, ntreated may lead to heart attack, heart failure, peripheral vascular disease, kidney damage, or stroke
BP points to remember
Measurements on the dial are in 2 mm HG increments, always ask the patient for the arm they prefer BP to be taken. Do not use the side with surgery, IV, or stroke
Responsibility and delegation for vital signs
Nurses can delegate the activity of taking vital signs
Nurses are responsible for vital signs
Interpretation of vital signs, vital sign trends, decisions based on abnormal findings
Purpose of the Nursing Process
To help the nurse provide goal-directed, patient-centered care; a thinking template to make clinical judgement; the art of nursing - based on knowledge, experience and intuition
Why do we use the nursing process?
Required by the American Nurse’s Association in the Nursing scope and standards of practice, Required by State Boards of Nursing in US, and Required for facility Accreditation
ADPIE
Assessment, Diagnosis, Planning, Implementation, and Evaluation
Assessment
Collect facts and data
Objective data
Lab test, V/S, someone else comes in and they will get very similar results
Subjective data
Patient, family , caregiver, etc. Ex: the patient says they are nauseous
