Q

What happens if the uterus is flaccid after detachment of all parts of the placenta

17
Q

What are the common causes of subinvolution

A

Retained placenta fragments and pelvic infection

18
Q

What are the signs and symptoms of subinvolution

A

Prolonged lochia discharge, irregular or excessive bleeding, hemorrhage

19
Q

How do we treat subinvolution

A

ergotrate or methergine

These drugs will contract the uterus

20
Q

What is the initial management for excessive postpartum bleeding due to uterine atony

A

Fungal message

21
Q

T/F ergonovine and methergine are contraindicated in the presence of hypertension or cardiovascular disease

22
Q

Define hypovolemic shock

A

It is a physiological compensatory mechanisms that are activated in response to hemorrhage.

23
Q

What is the circular pattern of hypovolemic shock

A

Decreased profusion, increased tissue anoxic, acidosis, edema formation, pooling of blood further decreasing perfusion. Cellular death

24
Q

What are the characteristics of hypovolemic shock

A
Rapid shallow respiration
Rapid weak and irregular pulse
Decreasing BP
Cool, pale, clammy skin
Decreased urinary output
Lethargy, anxiety ---> coma
Decreased central nervous pressure
25
What interventions need to be initiated when hypovolemic shock is suspected
Call for assistance Start IV Ensure patent airway give oxygen 10-12L Monitor vitals
26
What is idiopathic immune thrombocytopenic purpura
Autoimmune disorder in which antiplatelet, antibodies decrease the life span of the platelets
27
What are the common diagnostics findings of ITP
Thrombocytopenia, capillary fragility, increased bleeding time
28
How do we treat ITP
Corticosteroids, IV immune globulin, platelet transfusion
29
What is disseminated intravascular coagulation
An imbalance between the body's clotting and fribrinolytic systems
30
DIC can occur as a result
Hemorrhage, abruption placentae, amniotic fluid embolism, dead fetus syndrome, preeclampsia, sepsis, saline abortion, acute fatty liver
31
Diagnosis of DIC is made by which presenting clinical findings
Excessive bleeding, spontaneous bleeding, tachycardia, diaphoretic
32
How do we manage DIC
Correcting cause, volume replacement, optimizing oxygenation and perfusion
33
Because renal failure is one consequence of DIC, unitary output is
Closely monitored and must be maintained at more than 30ml/hr
34
Describe what a venous thromboembolism
Formation of a blood clot inside a blood vessel and is caused by inflammation or partial obstruction of the vessel
35
What is the medical management for DVT
Initial IV therapy w/ heparin bedrest Legs elevated Oral warfarin for 3months
36
Are pregnant women allowed to take Coumadin (warfarin)
No, it is contraindicated | Lactating women can
37
What is endometritis
Infection of the lining of the uterus
38
What is a genital fistulas
Abnormal passageways b/w genital tract organs
39
What are the common signs and symptoms of vaginal fistulas
Presence of urine, flatus, feces in the vagina, odors, irritation
40
T/F Women with a history of asthma should not receive Methylprostaglandin (Carboprost (hemabate) because it causes bronchoconstriction
True
