The Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"C"},"D":{"answers":"C"},"E":{"answers":"B"}}
A. Formation of fingers, toes, and facial features
Correct Trimester: 1st Trimester (Conception – 13 weeks)
Explanation:
By the end of the 1st trimester, organogenesis (organ formation) is largely complete.
-
Weeks 7–8: Limb buds appear and begin differentiating into arms and legs.
-
Weeks 9–12: Fingers, toes, facial features (eyes, nose, lips, ears) become clearly defined.
This is a critical period for congenital malformations if exposed to teratogens.
B. Fetus can hear and respond to external stimuli
Correct Trimester: 2nd Trimester (14–26 weeks)
Explanation:
-
Around 18–20 weeks: The fetus develops the ability to hear sounds.
-
External sounds can startle the fetus, and the heartbeat may change in response.
-
Mother's voice and music can be recognized at this stage.
C. Increase in body fat reserves
Correct Trimester: 3rd Trimester (27–40 weeks)
Explanation:
-
In the final trimester, especially after week 32, fat accumulates under the skin.
-
This provides energy and helps with temperature regulation after birth.
-
The fetus also gains the most weight during this period.
D. Brain develops most rapidly during this time
Correct Trimester: 3rd Trimester (27–40 weeks)
Explanation:
-
Although brain development starts early, the most rapid growth occurs in the third trimester.
-
There's a dramatic increase in brain volume, cortical folding, and neural connectivity.
-
This trimester is essential for cognitive and motor development.
E. Gender can be determined
Correct Trimester: 2nd Trimester (14–26 weeks)
Explanation:
-
By week 18–20, an ultrasound can reliably show external genitalia.
-
The sex organs begin forming in the 1st trimester, but become distinct and visible by the 2nd trimester.
-
This is when many parents find out the baby's gender via an anatomy scan.

Related Questions
Correct Answer is ["A","B","C"]
Explanation
Choice A rationale
Interviewing the client privately ensures confidentiality and allows for honest disclosure of the situation without fear of intimidation or manipulation by accompanying individuals. This approach is critical in identifying domestic abuse victims and initiating proper interventions.
Choice B rationale
A calm, caring, and professional demeanor fosters trust and reduces the client’s anxiety or fear. It ensures the nurse-patient relationship is non-threatening, encouraging the teen to open up about her experiences and facilitating accurate assessment and care.
Choice C rationale
Assessing whether the teen feels safe helps identify her immediate risks and the presence of a potential threat. Recognizing unsafe living conditions enables the nurse to involve appropriate protective and social services to ensure the client’s safety.
Choice D rationale
Contacting the police should be done only with the client’s consent unless mandated by law. Immediate police involvement without consent may jeopardize the client’s trust in the healthcare system and compromise her willingness to seek help in the future.
Correct Answer is B
Explanation
Choice A rationale
Thanking the nurse for information does not provide an actionable or measurable response to the safety plan. It signifies acknowledgment but does not demonstrate engagement or utilization of the resources provided. Effective evaluation involves observable actions that reflect the client's commitment to safety measures, such as storing or sharing resources.
Choice B rationale
Storing the crisis center number in their phone indicates the client values the provided resource and anticipates using it if necessary. It shows a proactive step in engaging with the safety plan and retaining information for future use. This measurable action demonstrates their awareness of the importance of having immediate access to help during emergencies.
Choice C rationale
The belief that their home will become safer due to the presence of a baby reflects denial or false optimism. It fails to address the inherent risks of intimate partner violence, which often escalate during stressful situations. A rational evaluation involves recognizing danger and taking steps to access resources for safety.
Choice D rationale
Choosing not to leave their home indicates resistance or inability to engage with the safety plan effectively. It reflects a lack of readiness to act on safety measures, making this response inappropriate as a measure of evaluating the safety plan. Behavioral change is necessary to ensure the client's well-being.
