Which of the following therapeutic applications provides the most accurate information related to uterine contraction strength?
a. External fetal monitoring (EFM)
b. Internal fetal monitoring
c. Intrauterine pressure catheter (IUPC)
d. Maternal comments based on perception
ANS: C
IUPC is a clinical tool that provides an accurate assessment of uterine contraction strength. EFM provides evidence of contraction pattern and fetal heart rate but only estimates uterine contraction strength. Internal fetal monitoring provides direct evidence of fetal heart rate and contraction pattern. It only estimates uterine contraction strength. Maternal comments related to pain may not be related to uterine contraction strength and thus are influenced by the client's own pain perception.
