A 17-year-old female receives treatment for primary amenorrhea caused by hyperthyroidism. Which finding during a clinic visit should indicate to the nurse that treatment for amenorrhea was effective?

A. An increased weight may help with initiating a menstrual cycle if the cause is a body fat composition of less than 10%, but this does not indicate that the woman has started her menstrual cycle. B. If the client is not menstruating (amenorrhea), she will not have menstrual cramps. C. Hyperthyroidism and a body fat composition of less than 10% can be contributing factors to amenorrhea (absence of menses). The start of a menstrual cycle indicates that treatment of the underlying cause of amenorrhea is effective. D. The absence of a fine hand tremor may indicate treatment is effective for the hyperthyroidism. It does not indicate that the primary amenorrhea is resolved.
