Fundamentals of Nursing
TYPES OF NURSING INTERVENTION
INDEPENDENT
DEPENDENT
INTERDEPENDENT
INDEPENDENT
Within scope of nursing practice
Part of the Philippine Nursing Law or R.A 9173
Health education, positioning and transferring
Does not require a doctor’s order
DEPENDENT
Requires a doctor’s order
Prescribing antibiotics
Malpractice if outside the scope of nursing
INTERDEPENDENT
Collaborative
Can be done with different therapists and dietician (specialties)
NURSING CARE DELIVERY SYSTEMS
FUNCTIONAL
TOTAL PATIENT CARE
TEAM NURSING
PRIMARY NURSING
CASE MANAGEMENT
FUNCTIONAL
Task based nursing care
Non holistic care
Most economical
TOTAL PATIENT CARE
Shift-based nursing care
Holistic only until the end of the shift
A different patient may be assigned already to the nurse
Concern: continuity of care
TEAM NURSING
Involves collaboration
Group of HCP takes care of a group of PT
RN, LPN, UAP - assign and delegate tasks accordingly
Competence is important with delegation
PRIMARY NURSING
24 hour nursing care
Involved from admission to discharge
Primary nurse develops nursing care plan with the associate nurses who continues the care
CASE MANAGEMENT
Coordinating different health care services
Calls for the physician and nurses
Case manager does not do bedside care
“Mangingialam” - hired by the HMO (health maintenance organization = insurance + health maintenance)
Goal is for the patient to be discharged early
To reduce out of pocket health care spending

Advance beginner - minimal acceptable performance (75%)
Competent - 2-3 yrs of nursing experience, with confidence
Proficient - 3-5 yrs of nursing experience, holistic view
Expert - >5 yrs of nursing experience, fluid, intuitive
VITAL SIGNS
Reflects physiologic functioning of the body
TEMPERATURE
Hypothalamus - temperature regulating center
Infant w/ infection -> hypothermia; immature hypothalamus
Elderly w/ infection -> CNS changes (restless, confusion)
2 types of body temperature:
Surface - superficial e.g. axillary
Core - deep tissue, more accurate e.g. rectal (most accurate), oral, tympanic
Estimation of normal body temp: 36.5 to 37.5 deg celsius
Fever: 37.5 to 38.5 deg celsius
Do not give paracetamol right away
High fever: > or = 38.5 deg celsius
Immediately give paracetamol
Temperature conversion:
Factors affecting body temperature:
BMR (Basal Metabolic Rate) - slow metabolism, cold temp; fast metabolism, hot; hypothyroidism low temp ‘n cold intolerance
Environment
Time of the day / circadian rhythm - body clock
Lowest: 4-6 AM
Highest: 4-6 PM
Infection
Types of Fever
Intermittent Fever - on ‘n off fever WITHIN THE DAY
Relapsing Fever - on ‘n off OVER FEW DAYS
Constant Fever - continuous high fever < 2 deg C of MINIMAL fluctuations
Remittent Fever - continuous high fever with WIDE fluctuations >2 deg C
HIGH Temp = inc pulse, inc RR, dec BP (vasodilation)
Methods of temp taking
Oral - side of frenulum, ask if pt ate or drink hot or cold temp then wait for 30 mins before taking, not best for children may be uncooperative; 3rd most accurate
Rectal
Most accurate
Position: left sim’s position (colon arrangement) - ascending colon right, transverse colon left
Water based lubricant e.g. KY jelly
Insert: 1-2 inches, labatiba 3-4 inches
Contraindicated: hemorrhoids, rectal surgery, heart problems, diarrhea, inc ICP, dec platelet (due to risk for bleeding)
No to vagus nerve stimulation CN X - runs from heart to pwet -> slower HR
Axillary - safest, pat dry
Tympanic
2nd most accurate
Child for 3 y/o below - pinna down n back
Adult 4 y/o up- pinna up n back
Not for px with ear infection
Temporal artery
Should be in contact for more accurate results
Slide from center of forehead to temporal artery
PULSE
Reflection of heart beat and circulation
Pulse deficit = Apical pulse – peripheral pulse
For dysrhythmias or atrial fibrillation
Popliteal, temporal
Pulse strength or amplitude
0 no pulse
1 faint pulse
2 slightly more diminished pulse
3 normal
4 bounding pulse (hypervolemia)
Stethoscope
Diaphragm - high pitch, heart murmur
Bel (LOW)l - low pitch
Normal heart sounds
Lub dub due to valve closure
AV valves - mitral (left), tricuspid (right); closes at same time
S1 - closure of AV valves
Semilunar valves - large blood vessels: pulmonary valve, aortic valve
S2 - closure of semilunar valves; pulmonary stenosis - split sound
S3 - CHF (congestive HF)
S4 - hypertension (resistance) - 4 syllables in hypertension
Apical Pulse or PMI - mitral area, 5th ICS LMCL
Angle of louis - 2nd ICS
RESPIRATION
Medulla oblongata - respiratory center (premature in infants)
Pons - rhythm of heart
Normal: 12-20
Apnea - 10 secs pause in breathing
Depth
Hypoventilation - shallow
Hyperventilation - deep
Rhythm
Cheyne-stokes - periods of hyperpnea & hypopnea & apnea; seen in dying patients; deep deep deep shallow shallow shallow stop
Kussmaul’s - rapid hyperventilation; DKA 350 mg/dL to release excess acids eg CO2; rapid deep respiration; form of compensation
Normal breath sounds
Vesicular - ALL AREAS except sternum scapula
I > E
Bronchial - TRACHEA
Tubular breath sounds
E > I
Bronchovesicular - STERNUM, SCAPULA
I = E
Abnormal breath sounds / Adventitious
Stridor - harsh sound during Inspiration
Airway issue, narrowing of airways
Eg laryngospasm - tetanus anaphylactic rxn epiglottitis
Equip: tracheostomy
Wheezing - musical sound during Expiration
Bronchoconstriction - asthma
Unting air nakakapasok
Bronchodilator
Rhonchi - snoring low pitch
Inc secretion in bronchi
Disappears with coughing
Cystic fibrosis
Crackles/ Rales - gurgling sound. + fluid in alveoli
Left sided heart failure, CHF, acute respiratory distress, severe pneumonia
More dangerous than rhonchi
Chest physiotherapy
Pleural friction - grating sound during Inhalation
Eg pleuritis / pleurisy
Pleuritic chest pain - prob is pulmonary in origin
BLOOD PRESSURE
Cardiac output x Total vascular resistance
Narrow = inc resistance; Wider = low pressure
Direct measurement - intra arterial BP monitoring, ICU
Indirect - aneroid, mercurial, digital
Rest for 30 mins, no smoke, coffee, exercise, outdoor
Use app bp cuff ⅔ cover extremities
TOO NARROW - False HIGH
TOO WIDE - False LOW
TOO LOOSE - FALSE HIGH
Wrap bp snugly
Arm level of heart
Above level - false LOW
Below level - false HIGH
Do not cross legs - false HIGH
Deflate bp cuff slowly rate 2-3 mmHg/sec
Listen to korotkoff sound
Phase I - systole
Phase II
Phase III
Phase IV
Phase V - diastole then silence
Pulse pressure = systole - diastole
Normal - 40
Narrow <30 - shock
Widened >50 - inc ICP
Do not confuse with pulse deficit
Hypertension - high bp on at least 2 occasions
2017 AHA 120/80 not normal
PAIN
Both subjective and objective
Acute - deviated VS, pupil dilation, bronchodilation except GIT GUT (dec salivation, indigestion, dec acid secretion, dec peristalsis, constipation, dec blood flow to kidney, urinary retention, oliguria)
Chronic pain - acetylcholine response, normal vital signs
White - more sensitive; Asians - stoic
Pain threshold - min stimuli to feel pain, almost same for everyone
Pain tolerance - max amt of pain willing to bear
Analgesics - pain reliever, give pain meds RTC
Non-opioids - reduce pain chemicals = alaxan, mefenamic acid, aspirin paracetamol, acetaminophen, Nsaids (ibuprofen, naproxyn - GI ulcer, should be taken w/ meals), cox-2 inhibitors (dec prostaglandin synthesis in blood stream - NO GI irritation)
Opioids - acts on thalamus in cerebral cortex (pain center) -> CNS depression
Morphine - better pain reliever, not for prolonged use
Do not give demerol for long term -> causes seizure
Codone, morphine - semi-synthetic
Strongest opioids - fentanyl 20x stronger than morphine
Check LOC and RR due to respiratory depression
Naloxone / narcan - antidote for opioid toxicity
Adjuvant drugs - antimalarial drugs for SLE and rheumatoid arthritis eg hydroxychloroquine
TCA / Tricyclic antidepressants - inc serotonin endorphin eg amitriptyline, imipramine
Endorphin - endogenous morphine
Gabapentin - post herpetic neuralgia, anticonvulsant
Best for neuropathic pain
Nonpharmacologic pain management
Physical intervention - massage
Cutaneous stimulation
Immobilization
TENS - transcutaneous electrical nerve stimulation; electric current delivered disrupts brain signals and chemicals to distract brain
Distraction
Biofeedback - control physiologic functioning (VS)
Guided imagery
PHYSICAL ASSESSMENT
Standard: IPaPeA
Inspection - observe color, size
Palpation - masses, tenderness, organ enlargement
Percussion
Dull sound - soft tissue
Resonant - lungs (AIR)
Hyperresonant - too much air eg COPD air trapping
Tympany - fluids eg ascites in liver cirrhosis
Auscultation
Bell(ow) - low pitched sound eg pulse
Diaph(igh)ragm - high pitched sound eg lung sounds
Abdominal assessment: IAPerPal / IAPePa - Yah Pe Pa (pig)
Each area 5 mins of auscultation of bowel sounds
Follow the pattern of large intestines
RLQ → RUQ → LUQ → LLQ
N bowel sounds 5-20 sounds / min
<5 bowel sounds / min - hypoactive / constipation
>20 min sounds - hyperactive / diarrhea
Key points for assessment
Respiratory - upright position, orthopnea for DOB
Abdominal - dorsal recumbent
Painful area palpated last
HEARING / AUDITORY ASSESSMENT
Whisper test: behind the patient, cover one ear, whisper approx 60 cm away from the uncovered ear, one ear at a time
Rinne’s test: air conduction vs bone conduction (Normal AC>BC; ABnormal BC>AC in conductive HL)
Weber’s test: lateralization, normal equally heard
2 types of hearing loss
Conductive HL: transmission does not reach ear eg otitis external media, otosclerosis; localize in poor ear
Sensorineural HL: nerve eg ototoxicity (CN VIII), meneire’s disease; localize in good ear
VISION TEST
Visual acuity: linaw ng mata
Snellen’s test 20/20 vision (adults) 10/10 (children)

WBC: 5k-10k; dec WBC in leucopenia high risk for infxn, inc WBC in leucocytosis infxn, inflammation
Neutrophils (most abundant wbc) - 1.5k - 6k cells / mm3
ANC = absolute neutrophil count - assess level / risk of infection
Mild risk for infxn 1k-1.5k
Moderate 500-1k
Severe <500
For moderate and severe, observe reverse / protective / neutropenic isolation

Palpation - during shower or when supine in bed
Soapy hands can more easily palpate mumps
Supine - small pillow under shoulder
Palpate for all areas of the breast and pinch nipples
Most common area of breast tumor - upper outer quadrant due to presencce of tail of spence (group of lymph node in axilla)
MAMMOGRAPHY
Xray of the breast - can detect lump earlier before it is palpated
Baseline: 35-39 y/o
Annually at 40 y/o
No deodorant, lotion, cream, powder - obscures view
Inform them of discomfort during the procedure - iniipit dede
Px can take about before or after mammography

FIRE SAFETY
FIRE EXTINGUISHER
For small fires
For beginning / incipient stages of fire
TYPES OF FIRE EXTINGUISHER
Class A (bo) ⃤⃤⃤ Ordinary combustibles - paper, plastic, wood, cloth
Class B (ox) ⃞ Flammable liquids - gasoline, oil, grease, paint
Class C (uryente) ◯ Electrical fires - office equipment
Class D (ecember) ☆ Metal fires - sodium, aluminum, magnesium, potassium
RACE PASS
Remove / rescue the patient (unahin sarili at lumabas ng bahay)
Activate the alarm / ask for help
Confine the fire
Extinguish the fire (under control if only one room is affected or the door knob is still not hot to touch)
Pull pin
Aim nozzle at the place of the fire (pailalim)
Squeeze
Sweep side to side
FALLS
MORSE FALL SCALE
May be source of malpractice
Assist every shift
If 50 and up - high risk (Fall - Fifty)
W/ hx of falling : Yes - 25
Secondary Dx : Yes - 15
Ambulatory aids : crutches / canes / crutches / walker - 15 ; furniture - 30
IV / Heparin Lock / FC (contraptions) : Yes - 20
Gait
Weak : 10
Impaired : 20
Mental status impaired : 15
PREVENTION
Fall alert - place near nurses station
Bed at lowest position
Side rails up - all side rails up not allowed considered as false imprisonment; only two to three is allowed
Call bell
Night light
Supervision
2 RISK FACTOR FOR FALLS
Intrinsic factor - within pt’s condition eg dizzy, mobility impaired, seizure disorder
Extrinsic factor - environmental eg unorganized, wet floor (better if carpet floor than tiled floor)
POSITIONING
Use gait belt then put one forward forward → slide to the floor
Position self behind the client - to easily catch patient
If w/ visual impaired - position self in front of client
DISASTER
EXTERNAL DISASTER
Outside the hospital
Eg house fire, terrorist attack
INTERNAL DISASTER
Within the facility
Eg fire within hospital
Rule of thumb: save as many people as you can (not necessarily the most critical)
