<prompt> Consider the following:1. Reactive NST2. Absence of deceleration3. Sinusoidal patternWhich of the above findings in an antepartum CTG indicate fetal well-being:1 and 2 only2 and 3 only1 and 3 only1, 2, 3  <response>: Ans. is a, i.e. 1 and 2 onlyRef. Dutta Obs. 7e, p 110, for 1, 612 for 2 and for 3; Williams 23e, p 420Reactive NST, i.e. acceleration with fetal movements indicates a healthy fetus.Absence of deceleration in the NST is reassuring. Absence of accelerations in the NST may be a sign of fetal compromise--Fernando Arias 3e, p 19Sinusoidal pattern is observed with serious fetal anemia, whether from D isoimmunization, ruptured vasa previa, fetomaternal hemorrhage or twin-to-twin transfusion. --Williams 25e, p 482
