Identify the trimester when each fetal development finding occurs. Note: Each category must have at least 1 response option selected.
Gender can be determined
Surfactant production
Sucking occurs
Fetus has a heartbeat
Fetal respiratory movements begin
Increase in body fat
The Correct Answer is {"A":{"answers":"B"},"B":{"answers":"C"},"C":{"answers":"C"},"D":{"answers":"A"},"E":{"answers":"C"},"F":{"answers":"C"}}
1st Trimester (Conception-13 weeks)
- Fetus has a heartbeat: The fetal heartbeat can typically be detected around 6 weeks gestation using ultrasound, marking the beginning of cardiac development in the first trimester.
2nd Trimester (14-26 weeks)
- Gender can be determined: Gender determination through ultrasound is generally possible around the 18-20 week mark in the second trimester when fetal genitalia are more distinguishable.
3rd Trimester (27-40 weeks)
- Surfactant production: Surfactant production by the fetal lungs begins in the third trimester, usually around 24-28 weeks, but continues to increase throughout the remainder of pregnancy.
- Sucking occurs: Fetal sucking movements start to develop around the 28th week and become more coordinated as the third trimester progresses.
- Fetal respiratory movements begin: Fetal respiratory movements, where the fetus practices breathing by moving the diaphragm, begin in the third trimester to prepare for life outside the womb.
- Increase in body fat: The fetus begins to accumulate more body fat in the third trimester, which helps with thermoregulation and provides energy reserves for birth and early postnatal life.

Related Questions
Correct Answer is ["A","C","D"]
Explanation
A. Fetal breathing. The biophysical profile assesses fetal breathing movements as one of the components indicating fetal well-being.
B. Fetal neck translucency. This is not part of the biophysical profile; it is typically assessed during first-trimester screening for chromosomal abnormalities.
C. Fetal motion. Fetal movements are another component of the biophysical profile, reflecting the fetal central nervous system integrity and oxygenation.
D. Amniotic fluid volume. The assessment of amniotic fluid volume is crucial in determining fetal well-being and adequate fetal renal function.
E. Fetal gender. Gender is not assessed as part of the biophysical profile; the test focuses on fetal physiological parameters related to well-being.
Correct Answer is ["B","C","E"]
Explanation
A. Stand directly in front of the client when talking: Standing directly in front of an agitated client can be seen as confrontational and might escalate the situation. It is better to stand at an angle and maintain a non-threatening posture.
B. Avoid wearing necklaces during client care: Wearing necklaces or other loose accessories can pose a safety risk if a client becomes aggressive and tries to grab or pull them, potentially causing injury.
C. Provide immediate verbal feedback for escalating behavior: Immediate feedback can help de-escalate potentially aggressive behavior by addressing issues before they become more serious. It also reinforces appropriate behavior and sets clear boundaries.
D. Bring security with you for all client interactions: Bringing security for all interactions is impractical and can create an atmosphere of distrust. Security should be involved only when there is a credible risk of violence.
E. Review the layout of the facility: Understanding the layout of the facility, including exits and potential hazards, helps in planning for safe interactions and knowing escape routes if a situation escalates.
