- anemia is normochromic, normocytic, with an elevated reticulocyte count.
- results in Hyperkalemia and hyperphosphatemia, uremia, metabolic acidosis, Fluid overload secondary to lack of glomerular filtration resulting in hemodilution and relative hyponatremia
- cause E.coli 0157 (produces a toxin and is contracted through contaminated water, meat, fruits, and vegetables).
- results in damage to endothelial cells and erythrocytes, producing a prodrome of hemorrhagic enterocolitis.
- Endothelial swelling of the glomerular arterioles in the kidneys results in decreased glomerular filtration rate, proteinuria, and hematuria with hemolytic anemia, thrombocytopenia, and acute renal failure.

19
Q
Pulmonary hypertension
A
- presents with hypotension, tachycardia, and then bradycardia, irritability, hypoxia, chest pain, seizures, decreased exercise tolerance
- treatment focused on managing the acute events by providing a stable environment and lowering pulmonary vascular resistance through stabilizing hemodynamics and treating acidosis and hypercarbia
- use of vasodilating agents is appropriate in both acute and chronic settings of pulmonary hypertension. Milrinone is a nonspecific vasodilating agent like sildenafil and prostaglandin which would be used first line in the treatment of pulmonary hypertension.
20
Q
AGVHD (acute graft versus host disease)
A
- a serious complication of allogeneic hematopoietic stem cell transplant which typically occurs in the first 100 days after transplant
- characterized by inflammation of the skin, liver, and gastrointestinal systems as a result of the donor cell’s immune response recognizing the recipient tissue as foreign.
- manifestations of AGVHD include generalized erythematous maculopapular rash which can progress to bullae formation and desquamation, hyperbilirubinemia, transaminitis, vomiting, diarrhea, abdominal pain, anorexia, mucosal sloughing, bloody stools, and ileus.
21
Q
Cryoprecipitate
A
-obtained by centrifuging plasma and removing the precipitate. -blood product used to replace low fibrinogen levels and assist in stabilizing coagulation disorders
22
Q
basilar skull fracture
A
- linear fracture at the base of the skull, typically occurs as a result of blunt trauma or crush forces to the head, presents with battle sign and raccoon eyes
- Battle sign is bruising noted behind the ears which can show up even a few days after the accident.
- Raccoon eyes include bruising and potential swelling around the eyes, indicative of a frontal basilar skull fracture.

- Meckel scan completed in nuclear medicine is the study of choice to best diagnose this problem.
- a complete blood count with differential and metabolic studies should be completed.

- Elevated protein, normal glucose and pleocytosis
- elevated opening pressure
36
cerebral perfusion pressure
- CCP = MAP – ICP
| - goal is >50
37
Myasthenia gravis
- neuromuscular disorder that is characterized by varying degrees of weakness of the voluntary skeletal muscles.
- symptoms include weakness that increases during periods of activity and improves after periods of rest
- therapy for myasthenia gravis includes an anticholinesterase medication (e.g. neostigmine), immunosuppressants (e.g systemic steroids, azothiaprine, cyclophosphamide), intravenous immune globulin, plasmapheresis, and thymectomy

- hemorrhage located between the dura mater and overlying skull often caused by trauma.
- symptoms include headache, vomiting, or irritability and often presents with a lucid interval.
- classic appearance is a biconvex or lentiform mass that pushes the brain away from the skull bone, does NOT cross suture lines.
