An Rh negative mother has just given birth to an Rh positive baby after 18 hours of
strenuous labor.Her rosette test was positive. Upon performing the Kleihauer-Betke
stain procedure, the percentage of fetal cells is found to be 1.9%. The mother's total
blood volumen is 5,000 ml. What dose of Rh Ig (RhoGam) should be administered to
the mother? - ANSWER 4 vials.
Rh immune globulin, also known as Rh Ig or RhoGam, is used to help prevent an Rh
negative mother from becoming sensitized to the D antigen from an Rh positive baby.
To do this, vials of Rh Ig must be administered correctly. One full dose vial (300ug or
equivalent) per 30 ml of D+ whole blood (15 ml D RBCs). To calculate how many vials
are needed, the following formula can be employed: KB% x blood volume - volume of
baby blood In this case: 1.9% x 5,000mL 95 mL baby blood in maternal circulation
95mL /30 mL per Rh Ig vial 3.17 vials This equals 3 vials (after rounding), with the
addition of 1 extra vial the mother should have 4 vials Rh Ig administered.
All of the statements below about synovial fluid are true EXCEPT:
- Arthrocentesis is performed as a means to evaluate arthritis and other joint disorders
- Synovial fluid is present only in movable joints
- Joint fluid resembles plasma in viscosity
- Joint fluid has approximately the same glucose as plasma - ANSWER Joint fluid
resembles plasma in viscosity
Synovial fluid is actually quite viscous and does not have the same consistency as
plasma. The reaso thicker consistency is to provide cushion and reduce friction between
the articular cartilage o during movement.
If a drug is given at intervals that are the same as its half-life, approximately how long
