The nurse knows that proper placement of the tocotransducer for electronic fetal monitoring is placed
Over the uterine fundus
On the fetal scalp
Inside uterus
Over the mother's lower abdomen
The Correct Answer is A
A. Over the uterine fundus: The tocotransducer measures uterine contractions by detecting changes in abdominal wall tension, which are most prominent at the uterine fundus. Placement over the fundus allows optimal detection of contraction frequency and duration, even though intensity is not directly measured. Proper placement is essential for accurate external monitoring of uterine activity.
B. On the fetal scalp: This placement is associated with internal fetal heart rate monitoring using a fetal scalp electrode, not with the tocotransducer. The tocotransducer is an external device and does not attach to the fetus or assess fetal heart rate directly.
C. Inside uterus: Internal monitoring of uterine contractions requires an intrauterine pressure catheter (IUPC), not a tocotransducer. The tocotransducer is noninvasive and placed externally on the maternal abdomen rather than inside the uterine cavity.
D. Over the mother’s lower abdomen: The lower abdomen does not provide reliable assessment of uterine contractions because contractions originate at the fundus and move downward. Placement here may result in inaccurate or weak contraction tracings.

Correct Answer is B
Explanation
A. 22-year-old with multiple partners: Individuals under 25 years of age and those with multiple sexual partners are at increased risk for chlamydial infection. Routine screening is strongly recommended to detect asymptomatic infections and prevent complications.
B. 35-year-old with a single partner: A woman in a monogamous relationship with no additional risk factors is at lower risk for chlamydial infection. Routine screening in this population is less urgent unless risk factors change or symptoms arise.
C. High-risk pregnant woman: Pregnant women at high risk for sexually transmitted infections require screening to prevent adverse maternal and neonatal outcomes, including preterm labor and neonatal conjunctivitis or pneumonia.
D. Sexually active 17-year-old: Adolescents under 25 are considered high-risk due to biological susceptibility and behavioral factors. Routine screening is recommended even in the absence of symptoms.
