The best time for her iron tablet
Iron is best absorbed on an empty stomach and with vitamin C. However, this client stopped her previous iron tablet because taking it before breakfast made her nauseated. When iron causes stomach upset, it can be taken with or right after food; a little less absorption is far better than not taking the drug at all. It must also be separated by about 2 hours from milk, calcium, and antacids, which reduce absorption. Taking it with orange juice right after lunch at 12:00 meets all of these rules.
Applying the rules to her day
| Option | Problem or benefit |
|---|
| With breakfast and milk at 07:00 | Milk and calcium reduce iron absorption |
| At bedtime at 22:00 with the antacid | Antacids reduce iron absorption |
| One hour before breakfast at 06:00 with water | Ideal for absorption, but it caused the nausea that made her stop |
| With orange juice right after lunch at 12:00 | Limits nausea, vitamin C aids absorption, well apart from milk and antacid |
Why adherence comes first
Watch out! The before-breakfast option follows the textbook rule for maximum absorption, which makes it tempting. But the question tells you this regimen already failed because of nausea. Iron therapy for iron deficiency anemia needs months of daily doses to correct the hemoglobin and refill iron stores, so a regimen she can actually continue is the priority. Her heavy menstrual bleeding over the past year, tachycardia, and near-fainting show significant anemia that needs consistent treatment.
Other teaching points
The nurse tells her that iron turns stools dark or black, which is expected. Constipation is common, so she should increase fluids and fiber. Tea and coffee taken at the same time also reduce absorption. Liquid iron preparations can stain the teeth and should be taken through a straw. She should keep iron out of reach of children, because iron overdose is dangerous in young children. She is also advised to return for follow-up of her hemoglobin and evaluation of her heavy periods, since treating the cause of blood loss is essential.
Exam takeaway
Take iron with vitamin C, away from milk, calcium, and antacids; if it causes stomach upset, take it with or after food rather than stopping it. Key point! When a stem tells you a past regimen failed, choose the option that solves that problem while keeping the other rules.
