- Q1Why is osteomyelitis so difficult to treat?Too many WBC's can get into the infected site , Once pathogens are introduced to the infected site antibiotics won't work anymore.The bone plate will not close completely causing future fractures to the patient, a deficet in calcium will cause pain to the patient.Hard to get sufficient levels of antibiotics to the area, Bone breakdown from infection impairs bone strength, once pathogens are introduced, it is hard for WBC's to get to them.It's difficult to treat due to their age, ethnicity and reason for the fracture, It's hard for osteoblasts to travel to the site of fracture and help in repair60s
- Q2What is the pathophysiology of osteoarthritis (OA)?cartilage destruction from physical wear and tearmultiple fractures in the affected jointexcess joint fluid puts pressure on the joint tissuesautoimmune cartilage destruction60s
- Q3Joint involvement is usually bilateralRheumatoid arthritisosteoarthritisanemiagout60s
- Q4obesity can cause it due to stress on the jointhip displacementosteoarthritisgoutrheumatoid arthitis60s
- Q5Most often affects the base of the great toerheumatoid arthitisgoutbreech at deliverycallus60s
- Q6can be classified as a metabolic disorder since theres usually increased uric acid production or clearencearthritisrheumatoid arthitiisosteoarthritisgout60s
- Q7what causes a stress fractureRepeated stress on a boneAn inherited disorder which makes the bone more vulnerable to fracture from pressureAn incident of excess force applied to a boneProlonged periods of increased exposure to catecholamines30s
- Q8Why are diabetics particularly prone to infections?more oxygen level to the tissues from RBC changes, Impaired WBC functionHigh glucose level is a feast for pathogens, Decreased sensations from neuropathies, Compromised circulation from vessel changes produced by a prolonged high glucose level, Less oxygen delivery to tissues from RBC changes, Impaired WBC functionLow glucose levels cause pathogens to increase and multiply, most diabetics are not able to control their blood sugar, medications are too expensive for majority of the population30s
- Q9Burn injuries make patients more prone to infections because:The fuel for the fire producing the burn may have had bacteria in it and it is difficult to remove it from a burnBlood vessel destruction decreases blood flow to the area so pathogens are harder to destroyBurn creams provide an excellent medium for bacteriaBurns compromise the first line of defense leaving the individual more susceptible to infection30s
- Q10Which diabetics usually have enough insulin receptors but make little or no insulin?Diabetes InsipidusGestational DiabetesDM Type 1DM Type 230s
- Q11ncreased histamine production makes most skin irritations of an allergic origin feel itchy.falsetrue30s
- Q12Why do many with type 2 diabetes often have increased levels of insulin before they become diabetic?The beta cells genetically over produce insulin and then stop making insulin.They have inherited a type of beta cells that are larger than normal and produce excess insulin but don't last as long.They break down insulin at a higher rate than others.Initially they produce greater amounts of insulin to lower excess blood sugar levels but eventually can't any longer.30s
- Q13Small areas of erythema without openings/breaks, on the skin of someone at risk for a decubitus ulcer usually requires no attention or treatment.falsetrue30s
- Q14What could result if a displaced fracture isn't properly reduced?A bone infection could developThere could be excess bleeding into the areaMalunion of the healed boneNo healing would occur30s
- Q15What is the most common cause of elevated levels of antidiuretic hormone (ADH) secretion?autoimmune diseaseCancerpregnancyheart failure30s
