NURS1202 Tutorial Study notes Tutorial 1: vital signs, patient admission, pain assessment, ISBAR Between the Flags: https://www.cec.health.nsw.gov.au/keep-patients-safe/Deteriorating-patientprogram/between-the-flags • Created by the CEC • It is designed to protect these patients from deteriorating unnoticed and to ensure they receive appropriate care if they do. • Acknowledging that early recognition of deterioration can reduce harm to patients and the earlier the better. • Establishing vital sign thresholds (calling criteria) for escalation and a clinical response team with advanced life support skill PQRST Pain assessment tool: • Pain is subjective • Self-report is considered the Gold Standard and most accurate measure of pain • Describe, assess & document • Documentation: o Patient’s understanding of the pain scale o Patient satisfaction with the pain level with current treatment modality o Timely re-assessment following any intervention and response to treatment o Communication with the physician o Patient education provided and the patients response to learning Vital Signs: • Core nursing foundation and key to the recognition of patient deterioration • Timely and accurate assessment, documentation and interpretation of vital signs is critical to clinical reasoning, accuracy of nursing diagnosis and implementation of appropriate interventions o Respirations: § Should be assessed when the person is relaxed § Rate, depth, rhythm, quality and effectiveness – breaths/minute § Normal range = 12-20 (adults) § Factors affecting: [increase] exercise, anxiety, stress, increased environmental temperature, lowered oxygen conc. at increased altitudes. [decrease] low environmental temperature, medications, increase ICP • Rate: b/min o Tachypnoea – quick, shallow o Bradypnoea – abnormally slow o Apnoea – cessation of breathing •
Volume: o Hyperventilation – overexpansion of lungs, characterised by rapid/deep breaths o Hypoventilation – underexpansion of lungs, characterised by shallow breaths

Rhythm: o Cheyne strokes – waxing and waning of respirations, from very deep to very shallow & temporary apnoea Ease/effort: o Dyspnoea – difficult/laboured. Individual has persistent, unsatisfied need for air and feels distress o Orthopnoea – ability to breath only sitting upright/standing positions Stridor: a shrill, harsh sound heard during inspirations with laryngeal obstruction Stertor: snoring or sonorous respirations, usually due to partial obstruction of upper airway Wheeze: continuous, high-pitched musical squeak/whistling sound occurring on expiration and sometimes on inspiration when air moves though narrow/partially obstructed airway Bubbling: gurgling sounds hears as air passes through moist secretions in the respiratory tract
Chest movements: o Intercostal retraction – indrawing between the ribs o Substernal retraction – indrawing beneath the breastbone o Suprasternal retraction – indrawing above the clavicles • Secretions/coughing: o Haemoptysis – blood in sputum o Productive – cough with secretions o Non-productive – dry cough with no secretions Oxygen Saturation: § Oxygen is carried in the blood as either dissolved oxygen or oxygen bound to haemoglobin in RBCs. § Normal range = >95% § The conc. of oxygen dissolved in the plasma is: partial pressure of arterial oxygen [PaO2] § The ratio of oxygen bound to haemoglobin compared with the oxygen-carrying capacity of the haemoglobin is: saturation of arterial oxygen [SaO2] § Oxygenation is measure as a correlated of the Pa02 & the Sa02 § Measure with a pulse oximeter • Two light-emitting diodes (LEDs) – one red and the other infrared – transmit light though nail, tissues, venous and arterial blood • Photodector placed directly opposite the LED – measure the amount of red and infrared light absorbed by oxygenated and deoxygenation blood and reports it as SaO2 § Factors affecting: haemoglobin, circulation, activity, dark-coloured nail polish/discolouration of nail bed, carbon monoxide poisoning Blood Pressure: § Measure of the pressure exerted by the blood as it flows through the arteries • Systolic: pressure as a result of ventricular contraction • Diastolic: pressure when the ventricles are at rest • Pulse pressure: the different between the diastolic and systolic •

Normal range = 120/80mmHg o Hypertension: persistent above normal. § Diastolic = >90mmHg § Systolic = >140mmHg
NURS1202 Tutorial Study notes Lack of physical exercise, heavy alcohol consumption, smoking, obesity o Hypotension: § Systolic = 85-110mmHg o Postural/Orthostatic hypotension: § Decline in SBP of at least 20mmHg & decline of DBP of 10mmHg within 3 minutes of standing o Cardiac output: the amount of blood the heart mechanically pumps out. Weak = lower CO [BP decreases], strong = high CO [BP increases} o Stroke volume: decrease in volume (haemorrhage/dehydration) = decrease in BP. Increase in volume (rapid IV infusion) = increase in BP o Peripheral vascular resistance: peripheral resistance = increase in BP (especially diastolic). § Factors that create resistance – capacity of the arterioles and capillaries, the compliance of the arteries and viscosity, internal diameter/capacity of arterioles/capillaries – small space within a vessel = greater resistance. § Vasoconstriction from smoking, or obstruction of arteriosclerosis increase PVR o Blood viscosity: BP increases when the blood is highly viscous (thick) – ratio of RBCs : blood plasma = high [ratio is called haematocrit]. Viscosity increases when haematocrit is >60-65% Factors affecting: age, exercise, stress, ethnicity, gender, medications, obesity, diurnal variations, disease process, hypo/hypervolaemia Assessing BP: • Sphygmomanometer & stethoscope • Measure brachial artery (upper arm) o Phase 1: [140-130] A sharp tapping o Phase 2: [130-120] A swishing or whooshing sound o Phase 3: [110-100] A thump softer than the tapping in phase 1 o Phase 4: [100-90] A softer blowing muffled sound that fades o Phase 5: [100 Bradycardia = 2) over a 24 hr period o Relapsing fever – short febrile periods of a few days interspersed with periods of 1 or 2 days of normal temp o Constant fever – fluctuates minimally but always remains above normal • hyperpyrexia – above 41 • Hyperthermia – C.temp greater than 40.6 • hypothermia – below normal temp (36.5) o excessive heat loss

Pain management: • unpleasant and highly subjective/personal/emotional experience associated with actual or potential tissue damage •
Types of pain: o Location: based on where it is in the body. determines the person’s underlying problems or needs § radiating pain: spread/expand to other areas – from lower back down to legs § referred pain: arising in different areas – cardiac pain in left arm/shoulder § visceral pain: arising from organs or hollow viscera § cancer pain: result from direct effects of the disease and its treatment o Duration: § Acute pain: sudden onset, sympathetic NS response, tissue injury/resolves with healing, crying, rubbing area, holding area § Chronic pain: +6months, parasympathetic NS response (normal v/s), dry/warm skin, pupils normal or dilated, continuous beyond healing, often doesn’t mention pain, behaviour absent o intensity: scale 1-10 o Aetiology: § physiological pain: experienced when an intact, properly functioning NS sends signals that tissues are damaged, requiring attention and proper care. • Somatic pain: originates in the skin, muscles, bone or connective tissue. (Sharp sensation of a paper cut or aching of a sprained ankle) • Visceral pain: results from activation of pain receptors in the organs/hollow viscera (tends to be poorly located – cramping, throbbing, pressing or aching. nausea, sweating, vomiting) • Neuropathic pain: damaged or malfunctioning nerves. may be abnormal due to illness, injury, or undetermined reasons. o peripheral neuropathic pain: phantom limb, post-herpetic neuralgia, carpal tunnel syndrome o central neuropathic pain: spinal cord injury pain, post-stroke pain, MS pain o Sympathetically maintained pain: abnormal connections between pain fibres and the sympathetic NS perpetuate problems with both the pain and sympathetically controlled functions (e.g. oedema, temp, blood flow regulation) o Concepts associated with pain: § pain threshold – least amount of stimulus that is needed for a person to label a sensation as pain
NURS1202 Tutorial Study notes pain tolerance – the maximum amount of painful stimulus that a person is willing to/able to withstand without seeking relief § hyperalgesia/hyperpathia – heightened response to a painful stimulus § allodynia – non-painful stimuli produces pain § dysesthesia – unpleasant/abnormal sensation – mimics/imitates the pathology of a central neuropathic pain disorder Physiology of pain: o nociception: refers to a signal arriving at the central nervous system as a result of the stimulation of specialised sensory receptors (nociceptors) in the peripheral nervous system § transduction: nociceptors can be excited by mechanical/thermal/chemical stimuli. • trigger the release of biochemical mediators (prostaglandins, bradykinin, serotonin, histamine, substance P) that sensitise nociceptors. • Noxious/painful stimulation also causes movement of ions across cell membranes that also excite nociceptors. §
•
Analgesics (ibuprofen/aspirin) block the production of prostaglandin (local anaesthetic) by decreases the movement of ions across the cell membranes transmission: 2nd process of nociception “transmission of pain” • 1st segment – pain impulse travels from the peripheral nerve fibres to the spinal cord (PNSàCNS) • Substance P (as a neurotransmitter) enhances the movement of impulses across the nerve synapse from the primary afferent neuron à second-order neuron in the dorsal horn of the spinal cord o 2 types of nociceptor fibres causes this transmission to the dorsal horn of the spinal cord: § unmyelinated C fibres – transmit dull/aching pain § thin A-delta fibres – sharp/localised pain o In the dorsal horn, the pain signal is modified by modulating factors (excitatory amino acids/endorphins) before the amplified or dampened signal travels via the spinothalamic tracts. nd • 2 segment – from the spinal cord and ascension, via spinothalamic tracts, à the brain stem à thalamus • 3rd segment – involves transmission of signals between the thalamus à somatic sensory cortex (where pain perception occurs) modulation: “descending system” • neurons in the thalamus/brain stem send signals back down to the dorsal horn of the spinal cord o descending fibres release substances (endogenous opioids, serotonin and noradrenalin) o inhibit (dampen) the ascending noxious impulses in the dorsal horn § [in contrast] excitatory amino acids (glutamate, N-methyl-daspartate (NMDA) and the up-regulation of excitatory glial cells can amplify these pain signals. the effects of the excitatory amino acids/glial cells tend to persist, while effects of the of the inhibitory neurotransmitters tend to be short-lived as they are reabsorbed into the nerves § Tricyclic antidepressants block the re-uptake of noradrenaline and serotonin •
§
§
NURS1202 Tutorial Study notes NMDA antagonists (ketamine, dextromethorphan) may be used to help diminish the signals of pain perception: person becomes conscious of the pain. • the sum of complex activities in the CNS that may shape the character and intensity of pain perceived and ascribe meaning to the pain o psychological context of the situation and the meaning of pain based on past experiences/further hopes help to shape the behavioural response that follows §
§
•
Responses to pain: o physiological: § activation of the sympathetic NS § increase in HR/BP, short/shallow breathing § reflexive movements – withdrawing from painful stimuli § stop activity, tense muscles • muscle atrophy/painful spasm à cardiac deconditioning, immobility § impairs immune function à slows healing, increases susceptibility to infections/dermal ulcers o psychological: § interferes with sleep, lowers appetite, decreases quality of life
•
Factors affecting the pain experiences: o Cultural values § influence a person’s reaction to pain and the expression of pain – some cultures are more prone to expressing pain than others § Middle Eastern/African – self-infliction is a sign of mourning § pain may be anticipated as part of the ritualistic practices à tolerance to pain signifies strength and endurance § Northern European – more stoic and less expressive of pain than Southerners • Nursing implications: o understand the effect of their own values and expectations about pain and ensure that they take steps to assess/evaluate these attitudes, so they do not make assumptions about the pain experienced by people o be sympathetic to concerns and develop skills needed to interact and communicate effectively and to undertake care that is culturally inclusive o Developmental stage: § Infants and children • less able than adults to articulate their experience tor needs = pain untreated • behavioural observations • environmental/non-pharmacological/pharmacological interventions are used to prevent, reduce and eliminate pain in neonates and children § Pubescent – growing pains, period pains § Women – more headaches, fibromyalgia, lupus § Men – more occupational/risk-taking behaviours § Older – increase prevalence of acute/chronic illness • Nursing implications: o very old/young, women, and ethnic minorities are at higher risk of being untreated for their pain Assessing pain: o Pain history: to help understand what pain means for the individual and how they are coping with it
