All of the following are possible side effects of oxytocin administration except?

Fetal hyperglycemia is not a typical side effect associated with oxytocin administration. Oxytocin is primarily used to induce or augment labor by stimulating uterine contractions. While it can lead to various maternal side effects, fetal hyperglycemia is not directly attributable to its usage.

When oxytocin is administered, it can lead to nausea and vomiting, which are potential responses due to its effects on the gastrointestinal tract. Additionally, tachysystole, or frequent contractions, may occur as a result of the uterine stimulation caused by oxytocin. Water intoxication is another possible complication due to the antidiuretic properties of oxytocin, which can lead to fluid overload if large amounts are administered without appropriate monitoring.

Understanding the pharmacodynamics of oxytocin and its effects on the mother and fetus is crucial, and recognizing that while it can have various adverse effects, fetal hyperglycemia is not typically one of them helps clarify its safety profile in perinatal care.
