For each scenario described below, choose the single most appropriate antenatal management from the above list of options. Each option may be used once, more than once, or not at all.

3. A 43-year-old woman, para 3, presents to the EPAU at 32 weeks of gestation with severe chest pain. Investigations are done diagnosed with pulmonary embolism. She is started on bolus dose of unfractioned heparin and APTT monitoring done. She is receiving UFH at rate of 18units/kg/hour as mantainence dose. Her APTT level after 6hours 1.2-1.5. what is the further management in this case?
4. A 40-year-old woman, para 2, presents to the obstetric day assessment unit at 28 weeks of gestation with reduced fetal movements (normal cardiotocograph [CTG]. Her notes indicate that she had DVT at 20 weeks of gestation during her current pregnancy and is on 80 mg LMWH twice daily. Her booking blood results were normal. However, her recent blood test reveals a platelet count of 60 x 109/L.
