Three composite women, one missed period and one pregnancy test ordered for all of them: the opening NU576 post shows how age rewrites everything that follows that test. Searches like "nu 576 unit 1 assignment example", "nu576 unit 1 sample" and "nu576 unit 1 example" land here.
One Negative Pregnancy Test, Three Different Next Questions: A Missed Period at 19, 34 and 53
NU576 · Unit 1 Discussion

All three patients are composites; no real person is described.
Initial Post
A missed period means pregnancy until a test says otherwise. After a negative test, the likeliest explanation shifts with each decade of reproductive life, and so does the risk worth naming.
The 19-year-old runner. Her urine hCG is negative. She runs about 55 miles a week and eats little on training days. The leading explanation is functional hypothalamic amenorrhea, in which energy deficit, training load and stress suppress the hypothalamic signal that drives the menstrual cycle. It is a diagnosis of exclusion, so thyroid-stimulating hormone and prolactin are still checked (Gordon et al., 2017). The risk worth naming is bone: low estrogen at the age when peak bone mass is still being built can leave her with thinner bones for life.
The 34-year-old off her pill. Her hCG is negative. She stopped a combined pill four months ago, and her periods have not returned. "Post-pill amenorrhea" describes the timing but explains nothing; most women resume cycles within three months, so her delay deserves a workup. TSH, prolactin and FSH are the first tests in the evaluation of secondary amenorrhea (Practice Committee of the American Society for Reproductive Medicine, 2008), with attention to signs of androgen excess that would suggest polycystic ovary syndrome. The risk worth naming is primary ovarian insufficiency, which an FSH in the menopausal range before age 40 would suggest, and which changes her fertility plans and her bone and heart health.
The 53-year-old whose cycles are spacing out. Her hCG is negative. Cycles of 60 days or more mark the late menopausal transition in the STRAW+10 staging system (Harlow et al., 2012). An FSH level adds little here, because it fluctuates widely during the transition and her age and pattern already place her. The risk worth naming is an unplanned pregnancy: ovulation can still occur, so contraception matters until a full year without a period.
So the pregnancy test opens all three cases, but it closes none of them. Each age brings a different next question.
Reply to Hana
Hana, your runner also had stress fractures last season. That shifts her from a menstrual question to a bone question, and I would ask about a DXA scan and an energy-availability assessment together.
Reply to Owen
Owen, you wondered whether the 53-year-old needs an FSH to "prove" menopause. I think the more useful question is whether she wants contraception or symptom relief now, because that choice, not the lab value, decides her plan.

How this NU576 Unit 1 example is structured
Claim, three short cases and a narrowing conclusion make up the post, and every case keeps one internal order, which lets each be set against the others: the pregnancy test and its result, the leading explanation for that age, the next test or the reason none is needed, and the risk worth naming. For the runner the risk is bone, because low estrogen from energy deficit thins it at the age peak bone mass is still being built. For the woman in her thirties it is primary ovarian insufficiency, which an elevated FSH before forty would suggest. For the oldest it is an unplanned pregnancy, since ovulation can persist through the transition. References follow the conclusion: the Endocrine Society's 2017 guideline on functional hypothalamic amenorrhea and the STRAW+10 staging system from 2012, each with its year.

NU576 Unit 1 questions, answered
Are three patients too many for one opening post?
Not when the prompt asks how a complaint changes across life stages, because the contrast is the argument. Where a word limit is tight, two patients at opposite ends of reproductive life can carry the same claim. What matters is that each paragraph names the leading explanation for that age and the test that follows; a general list of causes does not.
Should an opening post include laboratory values?
Only where a value changes the reasoning, such as an FSH level that would point toward ovarian insufficiency before forty. Otherwise the post can name the tests and what each result would mean. Invented patients should carry invented values, and a board post should avoid presenting any number as a treatment threshold for a real person.
Which sources suit a question about menstrual changes by age?
A staging framework for the menopausal transition, such as STRAW+10, and a guideline on the specific cause under discussion usually serve best. The Endocrine Society's guideline on functional hypothalamic amenorrhea is one example. Check your rubric for a recency window, and cite each source with its year, since undated references are a frequent small deduction on these boards.
