Final answer:
Fundal height is moderately correlated with gestational age, but various factors can affect this correlation, making it a general estimate rather than a precise measurement.
Step-by-step explanation:
The question asks how closely fundal height correlates with gestational age. The correct answer to the question is b) Moderately correlated. While fundal height is commonly used as a general estimate of gestational age, it's important to note that its accuracy can be affected by various factors such as a woman's body type, the amount of amniotic fluid, and the position of the baby. Because of these variables, fundal height is not a perfect measure but can give a rough estimate of the baby's growth and development stage. For clinical purposes, it is still used as a quick, non-invasive method for assessing fetal growth and pregnancy progression.
As a comparison, in the reference information provided, the relationship between height and weight is given as option d. As height increases, typically weight increases. This indicates a positive correlation. Likewise, for fundal height and gestational age, the correlation is positive but has its limitations and therefore is only moderate.
