Final answer:
Nursing actions for tachysystole with category 2 or 3 FHR focus on reducing fetal distress by administering oxygen, administering tocolytic medications, and possibly proceeding to an emergency delivery if necessary. Encouraging pushing or performing an amniotomy is not typically advised under these conditions.
Step-by-step explanation:
Nursing actions for tachysystole with category 2 or 3 Fetal Heart Rate (FHR) include various interventions. Administering oxygen is a common initial response to help increase the oxygen available to the fetus. Administering tocolytic medications is another intervention, aiming to relax the uterus and stop the excessive contractions that characterize tachysystole. Encouraging pushing would likely not be appropriate in the presence of tachysystole with a category 2 or 3 FHR tracing, as it could worsen fetal distress. Similarly, performing an amniotomy (deliberately breaking the amniotic sac) is not typically done during tachysystole with concerning FHR patterns, as the goal would be to relieve stress on the fetus rather than potentially increasing it.
Every contraction reduces oxygenated blood flow to the fetus, so periods of relaxation between contractions are critical. When contractions are too powerful or prolonged, as with tachysystole, there isn't sufficient time for oxygenated blood to restore to the fetus. This condition may necessitate an emergency delivery by vacuum, forceps, or a Caesarian section if the fetal distress is significant.
