Flashcards in Exam 1: Key Terms & Objectives Deck (24):
1

what is fibrinolysis?

3rd phase of hemostasis. (clot breakdown)

2

what are some of the treatment options for hyperkalemia?

stabilize heart with IV calcium

give IV insulin and glucose

hyperventilation

3

what is the least effective volume expander?

crystalloid b/c only 1/3 will remain IV

4

most common congenital bleeding disorder

VonWillebrand disease

5

more severe form of hemophilia?

B "Chirstmas Disease"

6

why shouldn't you use LR when administering blood products?

it contains Ca2+ which interacts with the citrate in PRBC and initiates clotting.

7

what kind of EKG changes are seen with hypocalcemia?

long QT interval or heart block

8

what is the etiology of Cl- depletion alkalosis?

pt with low Cl- levels, will hold on to HCO3 in the kidneys and citrate in PRBCs will be converted to HCO3 in liver.

9

anatomy of nephron

A image thumb
10

adverse effects of anemia

reduced O2 transport; weakness; fatigue; secondary organ failure

11

pathophysiology of pheochromocytomas

catecholamine-secreting tumor of the adrenal medulla

12

what is in cryoprecipitate?

The fraction of plasma that precipitates when FFP is thawed Each bag of Cryo contains ~ 200 mg of fibrinogen and 100 units of Factor VIII (80 to 110 IU)

13

what electrolyte disturbance can cause "U waves?"

K+ (Hypokalemia)

14

match the following disease with its hormonal abnormality

1.too much aldosterone

2. hypoplasia of thymus

3.too much cortisol

4.deficiency of aldosterone synthetase

5.vasopressin deficient

 

1. Conn syndrome

2. DiGeorge

3. Cushing's

4. hypoaldosteronism

5.Diabetes Insipidus

15

SBO (small bowel obstruction) and electrolyte disturbances

Causes N & V --> dehydration and loss of electrolytes (K+, Cl-, Na+)

16

pathophysiology of hemophilia A and B

Deficiency of FVIII = Hemophilia A Deficiency of FIX = Hemophilia B

17

causes of sickle cell crisis

dehydration; infection; increased O2 demand

18

effects of insulin the morning of surgery

later..............................

19

anion gap calculation

Na - (Cl + HCO3)

20

cause of Diabetes insipidus?

neurogenic (lack of vasopressin secretion) or nephrogenic (decreased response to vasopressin)

21

normal PT lab values

Normal: 10-14 seconds

22

treatment for lactic acidosis

THAM: tromethamine & O2 delivery

23

causes of respiratory acidosis

Alveolar hypoventilation, High PaCO2 Etiologies variable Lung disease Increased metabolic demand Multiple etiologies: neurologic, pharmacologic, trauma, sepsis, cardiac, pulmonary, etc.

24

indication of autonomic neuropathy

can be caused by DM --> problems with orthostatic hypotension
