Exam 1 Flashcards
What is health assessment?
systematic method of COLLECTING and ANALYZING data for the purpose of planning patient-centered care.
Physical Appearance and Hygiene Components of General Inspection (4)
-General Appearance: Any obvious findings like tremors or facial drooping?
-Age: Does the patient appear to be the stated age?
-Skin: What is the color and condition of the patient’s skin? Any variations in color? Any obvious lesions?
-Hygiene: Is the patient clean and well groomed? Any odors?
Body Structure and Position Components of General inspection (3)
-Stature: What is the patient’s position or posture? Does patient sit or stand straight up?
-Nutritional status: Well-nourished? Thin? Obese?
-Body Symmetry: Right and left sides of body symmetric in size?
Body Movement components of General Inspection (3)
-Patient’s movement: Does the patient walk or move with ease? Any use of assistive devices?
-Gait: Is the gait balanced and smooth?
-Involuntary movement: Any involuntary movements like tremors or tics?
Emotional/Mental Status and Behavior Components of General Inspection (6)
-Alert: Is patient alert to person, place, and time (AAO x 3)?
-Eye contact: Does patient maintain eye contact? (some cultural variations, so simply inquire)
-Conversation: Does patient converse appropriately?
-Facial expressions (affect) and body language: Appropriate for the conversation? Any distress?
-Dress/Attire: Is the patient dressed appropriately for the weather?
-Behavior Appropriate?: Is the patient’s behavior appropriate?
Questions to assess alertness (3)
-Person–Who are you?
-Place–Where are you located?
-Time–What day is it? What month is it?
4 components of general inspection
Physical appearance and hygiene
Body structure and position
Body Movement
Emotional/mental status
What is a health history?
information about the patient’s current state of health, current medications, previous illnesses and surgeries, a family history, personal and psychosocial history, and review of systems
Components of health assessment
Collect health history
Perform physical exam
Document data
Analyze and Interpret Data
Develop care plan
Signs
objective data observed, felt, heard, or measured.
Ex: rash, enlarged lymph nodes, and swelling of an extremity.
Symptoms
subjective data perceived and reported by the patient. Ex: pain, itching, and nausea
Primary data: from patient; Secondary data: from family
Types of health assessments

Shift
screening
6 vital signs
Temperature
Heart Rate
Respiratory rate
Blood pressure
Oxygen Saturation
Pain
Context of care
circumstances or situations related to health care delivery including setting and environment, nurse expertises, patient’s history
3 assessment techniques for physical exam
palpation
inspection
ascultation
When systolic and diastolic levels fall in different categories, how do you classify blood pressure
use the higher CATEGORY NOT the higher number
Normal blood pressure range?
less than 120/80 mmHg
Prehypertension Blood pressure range
Systolic: 120-139
Diastolic: 80-89
Hypertension Stage I range
Hypertension Stage I
Systolic: 140-159
Diastolic: 90-99
Hypertension Stage II range
Stage II
Systolic: > 160
Diastolic: > 100
Problem-based/focused assessment
involves a history and physical examination that is limited to a specific problem or complaint (e.g., a sprained ankle). Common in a walk-in clinic or emergency department. Nurse also considers the potential impact of the patient’s underlying health status.
Comprehensive assessment
detailed history and physical examination performed at the onset of care. It encompasses health problems experienced by the patient; health promotion, disease prevention, and assessment for problems associated with known risk factors; or for age- and gender-specific health problems.
Episodic/follow-up assessment
usually done when a patient is following up with a health care provider for a previously identified problem.
Screening assessment/examination (what is it and where performed)
short examination focused on disease detection.
May be performed in a health care provider’s office (as part of a comprehensive examination) or at a health fair.
Ex: include blood pressure screening, glucose screening, cholesterol screening, and colorectal screenings
Shift assessment:
during hospitalization, purpose is to identify changes to a patient’s condition from the baseline; thus the focus of the assessment is largely based on the condition or problem the patient is experiencing.
Inspection (any equipment?)
Visual and olfactory exam of patient
-pen light
tangential lighting
create shadows by directing pen light at a right angle
Palpation
feel for texture, size, shape, consistency, pulsation and location of certain parts of a patient’s body
Precaution for palpation
Nurse’s touch should be gentle, warm, and nails short. Must state purpose and need for touch, and manner and location of touch
Surfaces of hand best for palpation, vibration, temperature?
palmar surface and finger pads = more sensitive to palpation than fingertips.
ulnar surface of hand extending to fingertip = very sensitive to vibration
dorsal surface of hand (back) = more sensitive to temperature
Light palpation (depth and usage)
(approx 1 cm)
should be done PRIOR to deep palpation
Good for
assessing skin, pulsations, and tenderness
Deep palpation
approx 4 cm
-used to determine size and contour of an organ
Four characteristics of Auscultation
Intensity: loudness of the sound
Pitch: frequency of sounds. (High pitch =breath, low pitch =heart)
Duration: short, medium, or long. Layers of soft tissue can dampen the
duration of sound
Quality: hollow, dull, crackle
What is stethoscope good for and why
good for evaluating conditions of heart, blood vessels, lungs, + intestines because uses selective listening and blocks out extra sounds
4 things to do before stethoscope usage
-Disinfect stethoscope in between uses
- warm the head of the stethoscope
- remove distractions, quiet room is best for auscultating
-use on bare skin
3 Factors that can interfere with accurate auscultation:
-Pt gets cold/shivers + muscles contract and interfere with normal sounds
-Listening over clothing can be less accurate
-Friction of body hair rubbing can sound like abnormal lung sounds/crackles
How to perform rectal temp reading?
pt should be in Sim’s position with upper leg flexed. Insert 1-1.5 inches
What to know about rectal temp?
most accurate
Not performed often because it is invasive, less comfortable, requires more time, and has an increased risk of an infection compared to the others.
Types of Electronic thermometers
(how they work and accuracy of each)
oral, axillary, or rectal temperature. (1 below core temp, 2 below core temp, core temp)
Measures temperature of blood flowing near the tissue
What is Tympanic membrane thermometer?
inserted inside the ear, measures temperature of blood flowing near the tympanic membrane
Temporal artery thermometer (how it works and when accurate)
Detects heat emitted from pt’s forehead to behind the ear (temporal artery to temporal artery)
High accuracy in children over 2 yr old and adults in critical care
- avoid taking after extreme temps
Use of diaphragm vs bell of stethoscope
Diaphragm: large part for high pitch sounds like breath, bowels, normal HR
Bell: small part for low pitch sounds like extra heart and vascular sounds
What does automated BP device do?
senses blood flow vibrations and convert into electrical impulses
How to choose cuff size? What happens if wrong size?
Ideal cuff bladder: encircle 80% of upper arm
Ideal cuff width = cover 40% of circumference of limb
Cuff too wide = BP underestimated
Cuff too narrow = BP overestimated
Pulse oximeter
measures oxygen saturation in arterial blood + pulse rate. Will be accurate for oxygen saturation 70-100%,
Where to use pulse oximeter? When is it inaccurate?
-on highly vascular area (digits, ear lobes)
-inaccurate on cold digits or with nail polish
How to measure height in adults or older children? What to measure height in?
-Lower height attachment until it is in firm contact with the top of patient’s head (not bent), no shoes, eyes parallel to floor
-Height recorded in feet and inches OR centimeters for children, adolescents, adults
Two growth measures
height and weight
3 Height Influences
age, genetics, diet
How to measure weight?
use platform scale, no shoes, calibrated to 0 before use
- record in kg and pounds for older children and adults
What does sudden weight gain and loss indicate?
sudden increase: fluid volume
sudden decrease: disease
6 Weight Influences
Diet
Genetics
Age
Exercise
Health conditions
Fluid Volume
When is temperature the highest and lowest?
Diurnal variation means lowest in morning, highest in evening
How does menstruation and exercise affect body temp?
They increase it
What precaution to take for oral temp?
Wait 10 minutes if patient just smoked, had hot or cold liquids
-position under tongue
Why is axillary temp inaccurate?
2 degrees less than core b-c no major blood vessels in axillary
also many times it is not directly under arm.
Expected temperature ranges for adults (C and F)
from 96.4° to 99.1° F (35.8° to 37.3° C)
with an average of 98.6° F (37° C)
What to do with the ear in tympanic membrane temp readings?
tug up for over 3 yrs, tug down for under 3 yrs to straighten ear canal
Heart Rate range and average
60-100 beats/min, 70 beats/min
How to measure heart rate
- palpate pulse at the radial, brachial, carotid artery or by auscultating the heart
- measure number and rhythm
How does heart rate measurement differ by rhythm in adults?
if regular rhythm: count 30 secs x2 or 15 secs x4
If irregular rhythm: count full minute. Will be ‘regular irregularity’ or ‘irregular irregularity’
5 Respiratory Rate influences
-age
-fear
-anxiety
-exercise
-high altitudes
How do men, women, and children breath?
Men and children typically breathe diaphragmatically, while woman breathe thoracically
What 4 things to note when measuring respiratory rate?
Amount: ventilatory cycles per minute (measure 30 sec*2)
Depth: described as deep, normal, or shallow
Rhythm described as regular or irregular
Effort: if normal = even, quiet, effortless
Adult respiratory rates and oxygen saturation
12-20 breaths/minute
92%
What to know about pediatric blood pressure? (2)
-assessed routinely from age 3 and up
-usually lower than adult
Pulse pressure
difference between systolic and diastolic
Systolic vs Diastolic
systolic = maximum pressure exerted on arteries when ventricles contract or eject blood from heart. (1st korotkoff sound, top)
Diastolic = minimum amt of pressure exerted on vessels, when ventricles relax and fill with blood (5th korotkoff sound, bottom)
Direct vs indirect BP measurement
Direct: catheter in artery, reserved for critical care
Indirect: sphygmomanometer and stethoscope
Orthostatic hypotension
measure BP at sitting, laying, and standing; drop in BP
as patient goes from lying/sitting to standing
When can children use oral temperature?
Age 5 and up
Thermometers and findings for children under 5
Recommended route = axillary, tympanic membrane, and temporal artery (most accurate in children); rectal in febrile (1 in)
Finding: 98.6 F/37 C
Two reasons for low temperature variations in children
Low temperature from environmental exposure, and inability to regulate as newborns b-c skin thinner
3 reasons for high temps in children
High temperature associated with viral/bacterial infections, dehydration, and environmental exposure to heat
How to measure heart and respiratory rate for children?
Listen to apical pulse for FULL MINUTE, count respirations for FULL MINUTE with pediatric stethoscope (no palpation!)
Infants+children usually breathe diaphragmatically, observe abdominal movement
Expected vs abnormal pediatric HR and RR findings
Expected findings: elevation in HR and RR usually from crying, fever, respiratory distress, dehydration
Abnormal finding: decreased HR, can indicate serious condition
How measure infant height?
top of head to feet in supine
measure in inches or cm
How to measure infant weight
platform scale, no clothes or diaper
measure in oz or grams
Errors leading to false low BP (5)
-Arm ABOVE THE HEART
- Cuff too WIDE
- Not inflating cuff enough
- Deflating cuff too RAPIDLY (< 2-3 mmHg/sec)
- Pressing diaphragm too firmly on brachial artery
Errors leading to false-high BP (7)
- Legs crossed
-Arm BELOW THE HEART - Cuff too NARROW
- Cuff wrapped too LOOSELY/UNEVENLY
- Deflating cuff too SLOWLY (> 2-3 mmHg/sec)
- Reinflating cuff before completely deflating it
- Failing to wait 1-2 minutes before repeating measurement
How does age affect BP?
Age: From childhood to adulthood there is a gradual rise.
How does Gender affect BP
After puberty, females usually have a lower blood pressure than males; however, after menopause, a woman’s blood pressure may be higher than a man’s.
How does pregnancy affect BP?
During pregnancy, diastolic blood pressure may gradually drop slightly during the first two trimesters of pregnancy, but then it typically returns to the prepregnant levels by term.
How do Emotions affect BP?
Feeling anxious, angry, or stressed may increase the blood pressure.
How do personal habits affect BP?
Ingesting caffeine or smoking a cigarette within 30 minutes before measurement may increase blood pressure.
How does Weight affect BP?
Obese patients tend to have higher blood pressures than nonobese patients.
How does race affect BP?
The incidence of hypertension is twice as high in African Americans as in whites.
Pain
unpleasant sensory and emotional experience with actual or potential tissue damage
-whatever a person says it is
-6th vital sign
Pain threshold
point at which stimulus is perceived as painful, does not vary significantly over time
Pain tolerance
duration or intensity of pain that a person endures or tolerates before responding outwardly
