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.

Correct Answer is A
Explanation
A. Call the child abuse hotline. A spiral fracture, especially in a non-ambulatory infant, is highly suspicious for non-accidental trauma (child abuse). Reporting suspected abuse is mandatory to protect the child from further harm.
B. Educate the mother on safety. While important for prevention, addressing potential abuse takes precedence.
C. Inform the mother to call the nurse for all diaper changes. This does not address the immediate concern of suspected child abuse.
D. Complete the Morse Fall Scale. This is irrelevant in the context of suspected child abuse.
Correct Answer is ["C","D"]
Explanation
Answer: C, D
A. Hypertonia
Hypertonia, or increased muscle tone, is not a common characteristic of Trisomy 21. In fact, many infants with Down's Syndrome typically exhibit hypotonia, or decreased muscle tone, which can affect their overall strength and development.
B. Large ears
While individuals with Down's Syndrome may have unique ear shapes, "large ears" are not specifically characteristic of Trisomy 21. Instead, the ears may appear small or have a different shape compared to those of typically developing children.
C. Transverse palmar creases
Transverse palmar creases, also known as simian lines, are commonly seen in individuals with Down's Syndrome. This feature is a characteristic finding that can help in identifying the condition during physical assessment.
D. Protruding tongue
A protruding tongue is a common feature in individuals with Down's Syndrome. This occurs due to hypotonia of the oral muscles, which can lead to difficulties in tongue control and positioning.
E. Low birth weight
Low birth weight is not a defining characteristic of Trisomy 21. In fact, newborns with Down's Syndrome can have varying birth weights; they are often average weight or slightly above average, although some may be below average due to other factors related to maternal health or gestational issues.
