Patient Care II

The normal average rate of respiration for a healthy adult patient is between 12 and 20 breaths/min.
the total number of dissolved particles in solution per kilogram of water defines the osmolality of the contrast agent.
How noxious or harmful a contrast agent is Toxicity.
The thickness or concentration of the contrast agent defines the Viscosity. The viscosity of a contrast agent can affect the injection rate.
The ability of a contrast agent to mix with body fluids such as blood: Miscibility. Miscibility is an important consideration in preventing thrombus formation.
It is generally preferable to use a contrast agent with low osmolality and low toxicity because such an agent is safer for the patient and less likely to cause any untoward reactions.
The legal doctrine res ipsa locquitur relates to a thing or matter that speaks for itself. (For instance, if a patient went into the hospital to have a kidney stone removed and ended up with an appendectomy, that speaks for itself, and negligence can be proven)
Respondeat superior is the phrase meaning "let the master answer" or "the one ruling is responsible." If a radiographer were negligent, there may be an attempt to prove that the radiologist was responsible, because the radiologist oversees the radiographer.
Res judicata means a thing or matter settled by justice.
Stare decisis refers to a matter settled by precedent.
Systolic pressure is the contraction phase of the left ventricle.
Diastolic pressure is relaxation phase in the heart cycle.
Apnea describes cessation of breathing for short intervals.
Dyspnea refers to difficulty breathing in any body position.
Medical asepsis refers to practices that reduce the spread of microbes, and therefore the chance of spreading disease or infection. (i.e. washing hands, etc.)
An emetic is used to induce vomiting.
Cathartics are used to stimulate defecation (bowel movements).
Diuretics are used to promote urine elimination in individuals whose tissues are retaining excessive fluid
A Polyp is a tumor with a pedicle (stalk) that is commonly found in vascular organs projecting inward from its mucosal wall. Polyps are usually removed surgically because, although usually benign, they can become malignant.
A Diverticulum is an outpouching from the wall of an organ, such as the colon.
A Fistula is an abnormal tubelike passageway between organs or between an organ and the surface.
The normal creatinine range is 0.6 to 1.5 mg/mL.
Intravenous injections generally require that the needle form about a 15° angle with the arm.
For subcutaneous injections the needle should form a 45° angle.
Intramuscular drug injections usually require that the needle form a 90° angle of injection.
The four vital signs are temperature, pulse, respiration, and blood pressure.
Hematuria is blood in the urine.
The type of isolation practiced to prevent the spread of infectious agents in aerosol form is respiratory isolation.
Protective isolation, also referred to as reverse isolation is used to protect patients whose immune systems are compromised. Patients receiving chemotherapy, burn patients, or patients who are human immunodeficiency virus– (HIV) positive may all have compromised immune systems.
Contact isolation is used when there is a chance that infection may be spread by contact with body fluids. Gloves and a gown are used, and goggles and masks may be necessary if there is a chance of fluids spraying, such as in biopsy or drainage.
Strict Isolation is practiced with highly contagious diseases or viruses that may be spread by air and/or contact.
What 4 medications are found on a Emergency "Crash Cart" Heparin (to reduce coagulation), Norepinephrine (to raise bp), Nitroglycerin (acts a vasodiolator), or Lidocaine (used as a local anesthetic or antidysrhythmic).
Diverticulosis projections from/outpouchings of the intestinal wall.
