Exam 1 Fundamentals Flashcards
semi-fowlers
30-45 degrees, normally 30
Used for feeding, lung expansion, cardiac or respiratory conditions, for pts with a nasogastric tube
hypokalemia
symptoms: muscle weakness, chronic fatigue, and cardiac dysrhythmias
Leukopenia
condition where a person has a reduced number of white blood cells. This increases their risk of infections
leukocytosis
high WBC count
Z-track method of drug injection
for intramuscular injections to prevent leakage of medication into the needle track into subcutaneous tissue, thus minimizing discomfort.
procedure: attach a clean needle to the syringe after the syringe is filled with the medication to prevent the injection of any residual medication on the needle into superficial tissues. Pull the skin down or to one side 1 to 2cm (Yilmaz et al., 2016; Karch, 2020), spread the skin taut at the injection site, and hold in this position with the nondominant hand. Insert the needle and inject the medication slowly. After 10 seconds, withdraw the needle steadily and release the displaced tissue to allow it to return to its normal position. Massage of the site is not recommended because it may cause irritation by forcing the medication to leak back into the needle track. However, gentle pressure may be applied with a dry sponge.
gr (grains) to mg conversion
__ gr x 64 (conversino factor)= mg
ELISA test stands for and detects
Stands for: enzyme-linked immunosorbent assay
Uses what? Antibodies to detect the presence of a disease agent (bacteria, virus, or parasites) in your blood or body fluid
Thrombophlebitis typically develops in patients with which of the following conditions?
An impaired or traumatized blood vessel wall
The three factors of Virchow’s triad include intravascular vessel wall damage, stasis of flow, and the presence of a hypercoagulable state.
Immobility impairs bladder elimination, resulting in such disorders as:
Urine retention, bladder distention, and infection
Sources of Pain
cutaneous, somatic, visceral, referred, nociceptive, neuropathic
Cutaneous pain
superficial pain to the epidermis, dermis, or subcutaneous (burn, paper cut)
somatic pain
pain originating in structures in the body’s external wall
nerve, tendon, bones, muscles
visceral pain
pain originating in the internal organs in the thorax, cranium (migraine), or abdomen
poorly localized –> generalized
referred pain
the pain you feel in one part of your body is actually caused by pain or injury in another part of your body
heart attack causes pain in arm/shoulder/back
Nociceptive pain
type of pain caused by damage to body tissue
pain from a normal process that results in noxious stimuli being perceived as painful
feels like sharp, aching, throbbing
ex. stubbing your toe, sports injury, dental procedure
Neuropathic pain
my definition: abnormal processing of pain message
pain that results as a direct consequence of a lesion or disease affecting abnormal functioning of the peripheral nervous system (PNS) or central nervous system (CNS)
ex. phantom pain
described as burning, electric, tingling or stabbing
origins of pain
physical- can be identified
psychogenic- cause cannot be identified
the pain process
receive pain stimulus- activate the receptors(transduction)-
send a message via nerve fibers (transmission) to the thalamus- sensory center- heat, cold, pain, and touch are first perceived.
Then the cerebral cortex identify the intensity and location of the pain (perception)
brain messages to release endorphins & neuromodulators which are sent to diminish pain messages(modulation).
transduction
activation of pain receptors
transmission
conduction along pathways (A-delta and C-delta)
perception of pain
awareness of the characteristics of pain
modulation
inhibition or modification of pain
Bradykinin
a powerful vasodilator that increases capillary permeability and constricts smooth muscle
prostaglandins
important hormone like substance that sends additional pain stimuli to the CNS
substance P
sensitizes receptors on nerves to feel pain and also increases the rate of firing nerves
gate control theory of pain
describes the transmission of painful stimuli and recognizes a relationship between pain and emotions
sedation scale
S: sleep, easy to arouse: no action necessary
1: awake and alert; no action necessary
2: occasionally drowsy, but easy to arouse; no action necessary
3: frequently drowsy, drifts off to sleep during conversation; reduce dosage
4: somnolent with minimal or no response to stimuli; discontinue opioid, consider use of naloxone
sources of knowledge
traditional- passed down from generation to generation
authoritative- comes from an expert, accepted as truth based on persons perceived expertise
scientific- obtained through scientific method
deductive reasoning
examines general ideas and considers specific actions or ideas
inductive reasoning
builds from specific ideas or actions to conclusions about general ideas
nursing process follows this
general systems theory
theory for universal application; break whole things into parts to see how they work together in systems
adaptation theory
adjustment of living matter to other living things and environment (fluid)
developmental theory
orderly and predictable growth and development from conception to death
types of quantitative research
Descriptive
Correlational
Quasi-experimental
Experimental
qualitative research method
Phenomenology
Grounded theory
Ethnography
Historical
PICOT
P = patient, population, or problem of interest
I = intervention of interest
C = comparison of interest
O = outcome of interest
T = time
the helping relationship
orientation phase- establish goal of relationship, location frequency and length of contract, duration of relationship
working phase- longest phase, pt actively participates , works towards achieving mutually acceptable goals, pt will express feelings and concerns
termination phase- begins at hello, pt will participate in identifying the goals accomplished and progress made towards goals
aims of teaching and conseling
Maintaining and promoting health
Preventing illness
Restoring health
Facilitating coping
three learning domains
Cognitive: storing and recalling of new knowledge in the brain
Psychomotor: learning a physical skill, integration of mental and muscular activity
Affective: changing attitudes, values, and feelings
Knowles Assumptions about Adult Learners
most adults orientation to learning is that material should be useful immediately, rather than at some point in the future
teaching plans for older adults
Identify learning barriers.
Allow extra time.
Plan short teaching sessions.
Accommodate for sensory deficits.
Reduce environmental distractions.
Relate new information to familiar activities or information.
cognitive domain examples
lecture, panel, discovery, written materials
affective domain
role modeling, discussion, audiovisual materials
psychomotor domain
demonstration, discovery, printed materials

types of fever
intermittent, remittent, sustained or continuous, relapsing or recurrent
intermittent
temperature returns to normal at least one every 25 hours
remittent
temp does not return to normal and fluctuates a few degrees up and down
primary source of heat
metabolism
heat production
metabolism
hormones, muscle movements, exercise (all increase metabolism)
epi and norepi
thyroid hormone and shivering (increase heat production)
sources of heat loss
skin (primary source)
evaporation of sweat
warming and humidifying inspired air
eliminating urine and feces
transfer of body heat to external environment
radiation, convection, evaporation, conduction
radiation
Loss of heat by indirect contact
ex. placing a cold object inside incubator.
convection
Loss of heat from warm body to cooler air currents.
evaporation
Loss of heat due to conversion of water to vapor.
ex. sweating
conduction
Loss of heat by direct touch.
ex. ice pack on knee
pulse rate
number of contractions over a peripheral artery in 1 minute
pulse is regulated by
the autonomic nervous system through cardiac sinoatrial node
ventilation
movement of air in and out of lungs
diffusion
exchange of oxygen and carbon dioxide between the alveoli of lungs and circulating blood
perfusion
exchange of oxygen and carbon dioxide between circulating blood and tissue cells
