A client with iron deficiency anemia is taking ferrous sulfate elixir. Which instruction should the nurse provide this client?

1. First, convert the client's weight from kilograms to pounds:
   • 1 kg = 2.2 lbs
   • Step 1: 90 kg × 2.2 lbs/kg = 198 lbs
2. Since the client weighs less than 265.5 pounds, the protocol specifies cefazolin 2 grams/100 mL over 1 hour.
3. Determine the flow rate in mL/hr:
   • The total volume to be infused is 100 mL.
   • The infusion time is 1 hour.
   • Step 2: 100 mL ÷ 1 hour = 100 mL/hr

Therefore, the nurse should program the pump to deliver 100 mL/hr.

Choice A reason: Using a straw to ingest ferrous sulfate elixir is recommended because it helps minimize the staining of teeth, which is a common side effect of liquid iron supplements. This instruction helps protect the client's dental health while ensuring they receive the necessary treatment for iron deficiency anemia.

Choice B reason: Swallowing ferrous sulfate elixir undiluted is not recommended as it increases the risk of teeth staining and potential gastrointestinal irritation. It's better to dilute it or use a straw to minimize contact with the teeth.

Choice C reason: Taking ferrous sulfate with milk is not advisable because calcium in milk can interfere with iron absorption, reducing the effectiveness of the supplement. Clients should avoid consuming iron supplements with calcium-rich foods or beverages.

Choice D reason: Mixing ferrous sulfate with an antacid is not recommended because antacids can also interfere with iron absorption. Clients should avoid taking antacids close to the time they take their iron supplement.
