Final exam Flashcards
Barium swallow
Reason: Dysphagia: difficulty breathing
Area of interest: Deglutition, epiglottis, esophagus, soft palate
Enter: From mouth
Esophogram
Reason: Stricture, difficulty swallowing, foreign body, pain
Area of interest: Epiglottis, esophagus, proximal stomach
Enter: from mouth
Upper gastro-intestinal study
Reason: Pain, reflux, heartburn
Interest: Esophagus, stomach and proximal small bowel
Enter from mouth
Small bowel series
Reason: pain, masses/tumors, nausea
Interest: small bowel - duodenum to ileocecal junction
Enter: Swallow from mouth
Lower gastro-intestinal
Reason: Constipation, diarrhea, weight loss
Interest: Large colon
Enter: from mouth
Arthrorgram
Interest: any joint
reason: varied
Contrast injected into joint
Urography
Interest: urinary system
Reason: varies
Contrast injected intravenously or via catheter
Angiography
Interest: arteries throughout body
reason: varies
Contrasted injected directyl into artery
Cholangiography
interest: bile ducts
reason: blockage, stones
Contrast injected
Hysterosalpingogram
interest: uterus & fallopian tubes
reason: patency of fallopian tubes, abnormalities of uterus
Contrast introduced via catheter
Gastrointestinal
reason: same as barium studies
Contrast may be oral or injected
Myelography
interest: subarachnoid space of vertebral column
reason: pain, abnormal gait
Contrast injected into subarachnoid space, L3-L4
Cystogram (retrograde)
Demonstrates bladder only, contrast injected via catheter in urethra
Cystourethrogram
Demonstrates bladder and urethra
Contrast through catheter in urethra
Retrograde pyelogram
Demonstrates bladder, ureters & renal pelvis
Injected from catheter into urethrra
CT
Contrast injected intravenously
Iodine vs barium
Iodine: can be injected into arteries
Barium: can only be used for gastrointestinal, swallow, cannot be injected, if risk of perforations use iodine
Cultural competence
The ability of providers and organizations to effectively deliver health care services that meet the social, cultural, and linguistic needs of patients.
Why is cultural competence important in healthcare field?
Being culturally competent can help improve health outcomes and quality of care. It can also contribute to the elimination of racial and ethnic health disparities
How can we improve our cultural competence?
Understand and check your own biases.
Pharmacokinetics
What the body does with a drug, how it is absorbed, distributed, metabolized, excreted/eliminated
Drug abosrption
Crossing cell membrane, usually intravenous or intra-arterial injection
Drug metabolism
Drug has reached the intended destination and runs its course it is converted to a metabolite & purged from the body
What are the 3 routes for drug elimination/excretion from the body? What adverse effects might each route have?
Kidneys: Eliminate it via urine
Liver: eliminated in feces
Respiratory system: eliminated here
Pharmacodynamics
What the drug does to the body
Therapeutic effect
The desired effect of the drug
Side effect
Predictable effect of drug
Adverse effect
Any unwanted effect
Six right of drug administration
Right patient right medicaition right dose right time right route right documentation
Six routes of drug administration
oral: tablets, capsules
inhalation: liquid medications are vaporized and inhaled via inhaler
sublingual: Under the tongue
topical: drugs absorbed through skin
rectal/vaginal: absorbed by mucous membrane into bloodstream
parenteral: any route other than GI
Six parenteral routes
intradermal subcutaneous intramuscular intrathecal intravenous intra-arterial
Most common route for drug administation
Oral
Fastest route of drug administration
Parenteral
Bolus injection
High dose injection, delivered quickly
Ampule
Sealed glass container with a single dose, one time use
PPE
Personal protective equipment
4 types of isolation
Contact: wear gloves and gown, MRSA, C-diff
Droplet: wear surgical mask, Influenza, mumps
Airborne: Respirator mask, TB, chicken pox
Reverse: Mask, gloves, gown, Organ transplants
Surgical asepsis
Creating & maintaining area completely free of pathogens
PPE required for surgical area
Clean scrubs, shoe covers, cap
Is the technologist considered a sterile tea member in surgery?
No they are not
Sterile corridor
Area of surgical facility designated primarily for surgical cases and staff
5 methods of sterilization
Chemical: immerison and soaking instruments (least successful)
Autoclaving: Steam under pressure (most utilized)
Conventional gas: For items that cant withstand high temps
Dry heat: vacuum chamber with infrared heating element
Gas plasma: used in place of conventional gas, for items that can’t stand high temps
Indications item is sterile
Seal isnt broken, packaging isnt damaged, package isnt wet
Sterile tray setup
Place on clean surface, check expiration, break seal and open, unfold away from you first, unfold side
Sterile field in surgery
Pass back to back, everything in front and above waist, never reach across sterile field
Exams using sterile technique
Myelogram, arthrogram, hysterosalpingogram
Normal flow rate for IV drip
15-20 drops/min
IV bag
18”-20” above level of vein
Asepsis
Free from infection
Non aseptic
Not free of infection
What are microorganisms?
organisms too small to be seen without microscope
Pathogens
Microorganisms capable of causing disease
Types of pathogens
Protozoa: amoeba-like, unicellular, live together in colonies
Virus: simplest life form, cannot live outside cell
Bacteria: Rapid cell divison, endospore
fungi: Ring worm, yeast infections
Conditions for infection
Quantity & strength, reservoir, Exit door
Chain of infection
Pathogenic microorganism, resevoir, means of escape, mode of transmission, means of entry, host susceptibility
