Answer :
I would be happy to explain this in a clear and detailed manner. Although the provided answer was numerical and related to amounts and doses, let's tackle this question about spontaneous pregnancy loss.
Spontaneous pregnancy loss, or miscarriage, before 20 weeks of gestation is a common concern among expecting parents and healthcare providers. The given question asks for the approximate percentage of clinically recognized pregnancies that end in spontaneous loss before reaching the 20-week mark.
Option a: 30% - This figure is considered quite high for clinically recognized pregnancies. Epidemiological studies generally report a lower percentage.
Option b: 20% - This figure is at the higher end but within the range often reported by many studies, particularly when including early pregnancy losses that occur before the pregnancy is clinically recognized.
Option c: 10% to 20% - This range is frequently cited in scientific literature and clinical guidelines. It represents a more commonly accepted range based on available data, considering that some losses might not be clinically recognized.
Option d: 5% - This figure is lower than what is typically reported for spontaneous pregnancy loss before 20 weeks in clinically recognized pregnancies.
Given these options and the epidemiology of spontaneous pregnancy loss:
The correct answer is:
c. 10% to 20%
This aligns with a widely accepted understanding in the medical community and reflects the range most supported by clinical evidence.
