The patient is a composite; the iron amount is bracketed as a composite value and the plan is not dosing guidance.
1. Summary
Ms. [V.], 36, schedules freight for a trucking company. She reports two years of heavier periods, now soaking through protection several times a day at the peak of each cycle, and six months of fatigue and breathlessness on stairs. Her hemoglobin is 9.8 g/dL, the indices show microcytic, hypochromic cells, and ferritin is 6 ng/mL, which confirms depleted iron stores. The likely cause is menstrual blood loss exceeding dietary iron intake (Camaschella, 2015). Her current medicines are [pantoprazole] 40 mg daily for reflux, started three years ago, and a calcium carbonate antacid she chews most evenings.
2. Goal
The target is a hemoglobin rise of at least 1 g/dL at four weeks and a hemoglobin within the normal range by eight to ten weeks, followed by three further months of iron to refill the stores. A rise of 1 g/dL at four weeks is the benchmark for an adequate response to oral iron; a smaller rise means something is interfering and triggers the decision table below. Ferritin is the measure of stores, and the plan continues until ferritin has recovered.
3. Regimen
Oral ferrous sulfate, [composite amount] of elemental iron as a single tablet on alternate days, taken in the morning before breakfast, ideally with a source of vitamin C such as a glass of juice.
Why alternate days. An oral iron dose raises the hormone hepcidin for about 24 hours, and hepcidin blocks iron absorption from the gut. In iron-depleted women, a single dose on alternate days led to more total iron absorbed than the same dose on consecutive days (Stoffel et al., 2017), and a later trial in women with iron-deficiency anemia confirmed greater absorption with alternate-day dosing (Stoffel et al., 2020). Alternate-day dosing also tends to cause fewer gastrointestinal side effects, which helps adherence.
Why the timing matters for her. Her current medicines interfere with absorption. Iron is absorbed best in its ferrous form in an acidic stomach, and pantoprazole reduces stomach acid; long-term acid suppression has been associated with an increased risk of iron deficiency (Lam et al., 2017). Calcium also reduces iron absorption when taken together. The plan therefore:
1. Separates the iron tablet from the evening antacid by taking iron in the morning.
2. Takes iron at least an hour before pantoprazole, or asks whether pantoprazole is still needed.
3. Raises the acid question directly: three years of a proton pump inhibitor for reflux deserves review, and a step down to a lower dose or an as-needed regimen may be possible.
3a. What She Is Told
Iron turns stools dark green or black, which is expected and harmless; black, tarry stools with dizziness are not, and she should call. Nausea and constipation are the common side effects. Taking the tablet with a small amount of food is acceptable if nausea would otherwise make her stop, even though absorption falls somewhat. Iron tablets are dangerous to young children, so they are kept out of reach. She is asked to mark the days she takes the tablet on a calendar, which makes alternate-day dosing easier to follow and gives the week-4 visit an honest adherence record.
4. Monitoring
Dates are derived from the physiology of the response.
1. Week 1 to 2: reticulocyte count rises within about a week of starting effective iron; checking it is optional but confirms an early response if doubt arises.
2. Week 4: complete blood count. Hemoglobin should have risen by at least 1 g/dL.
3. Week 8 to 10: complete blood count. Hemoglobin should be within the normal range.
4. Month 3 after hemoglobin normalizes: ferritin, to confirm stores are refilling.
5. At each visit: side effects, adherence and whether bleeding has changed.
5. Decision Table
1. At week 4, hemoglobin up at least 1 g/dL: continue the regimen; recheck at week 8 to 10.
2. At week 4, hemoglobin up less than 1 g/dL: check four causes in order.
a. Adherence and side effects: is she taking it, and is nausea or constipation stopping her? b. Continued bleeding: are her periods still heavy, and is there another source? c. Absorption: is acid suppression still full-dose, is she taking iron with calcium, and has celiac disease been excluded? d. Diagnosis: is this iron deficiency alone, or is there another cause of anemia?
3. After addressing those, still below target at week 8: refer for intravenous iron, which bypasses gut absorption and hepcidin and replaces stores in one or two infusions.
4. At any point, hemoglobin falling, heavy bleeding with dizziness or breathlessness at rest: urgent assessment.
6. Addressing the Cause
The iron treats the deficiency; it does not treat the bleeding. A gynecology referral for evaluation of heavy menstrual bleeding is made on the same day as the prescription, with an appointment date recorded in the plan. Evaluation may identify fibroids, polyps or a bleeding disorder, and treatment options range from hormonal therapy to procedures. Without it, the iron deficiency is likely to return once the tablets stop.
7. End Date
Once her hemoglobin is normal, iron carries on for roughly another three months so the stores can refill, and stops when ferritin has recovered. If hemoglobin normalizes at week 10, the planned end date is about week 22, confirmed by a ferritin at that visit. If heavy bleeding continues, a maintenance plan or recurrence check every six months will be needed.

How this NU553 Unit 4 example is structured
The plan is written in the order a reviewer would audit it, goal before regimen, so the drug choice can be judged against a target that already exists. Her existing list belongs to the plan itself: pantoprazole lowers the stomach acid that keeps iron soluble and absorbable, and calcium in the antacid reduces uptake further, so the regimen section times the tablet away from both and asks whether the acid suppression is still needed. Monitoring dates are derived from physiology, reticulocytes responding within about a week and hemoglobin measurably within a month. The failure branch is specific: adherence and gastrointestinal effects, continued bleeding, malabsorption such as celiac disease, then the intravenous route. The cause is not left to the iron: a gynecology referral for the bleeding appears as a line item with its own date.

NU553 Unit 4 questions, answered
Why does the plan address the patient's other medications?
Because a new agent enters a body already taking things, and some of them change how it works. Here the acid suppressant and antacid reduce iron absorption, which could make the plan fail for reasons unrelated to the iron itself. A plan that checks the existing list first can explain a poor response before it happens, and that foresight is what earns the credit here.
Should the plan include an end date even for long-term drugs?
It should include a point of review, even when stopping is unlikely. For a course like iron repletion, the end is concrete: stores refilled and the cause addressed. For a chronic agent, the plan names the date and the finding that would prompt reconsidering it. Either way, the reader can see that continuing is a decision, not a default.
May the plan name a specific tablet strength?
If the prompt requires it, state it with where it came from, a guideline or a labeled product. The sample brackets the amount as a composite, because a plan's quality in this unit rests on the goal, the monitoring and the decision rules around the regimen. The sample recommends nothing for any actual patient's iron therapy.
