A
  • Enlarged liver and spleen
  • Vascular hypertonicity
  • Congestive heart failure
  • Hydrops fetalis

A

Predicts fetal anemia or destruction of fetal RBCs

Monitoring this velocity helps assess the risk of hemolytic disease.

100
Q

What is the significance of a high ratio in anti-D antibody titer?

A

Indicates Rh sensitization

A ratio of 1:16 or above necessitates monitoring and potential interventions.

101
Q

Fill in the blank: HIV can be transmitted through _______.

A

Body secretions

This includes semen, vaginal fluids, and breastmilk.

102
Q

What is the goal of medical management for HIV?

A
