16
Q

Iron Therapy med

A

Ferrous sulfat

17
Q

Ferrous Sulfate MOA

A

Taken up by bone marrow cells to make Hgb

18
Q

AE of ferrous sulfate

A

GI disturbances, teeth staining with liquid form, tarry stools

19
Q

Dosage issues of iron therapy

A

Ferrous sulfate only contains 20% elemental iron by weight (elemental is 100% absorbed)

20
Q

Interactions with iron therapy

A

Antacids reduce absorption, food helps to prevent GI SE but it also decreases absorption by 50-70%

21
Q

Signs of toxicity with iron therapy

A

Stomach pain, N/V/D

22
Q

Parenteral Iron Therapy med

A

Iron Dextran

23
Q

Indication for Iron Dextran

A

Clear diagnosis of iron deficiency, oral iron is intolerable or ineffective

24
Q

AE of iron dextran

A

potentially fatal anaphylaxis

25
Q

Safety implications for iron dextran (parenteral iron)

A

Only use when you absolutely have to, keep epinephrine and CPR equipment available, do a small test dose and monitor for five minutes before full administration, monitor for 15 minutes after administration

26
Q

Disadvantages of Iron Dextran IM

A

Persistent pain, discoloration, tumors, risk of anaphylaxis

27
Q

Why is it important to use the Z track method with Iron Dextran?

A

To reduce the discoloration. Iron can leak from the muscle into the tissue and cause discoloration.

28
Q

Vitamin B12 med

A

Cyanocobalamin

29
Q

Route for B12

A

Oral

30
Q

AE of B12 (Cyanocobalamin)

A

Hypokalemia

31
Q

Why are we cautious when we use B12 and folic acid together?

A

Folic acid corrects the anemia through stimulating RBC production, but can mask the B12 deficiency

32
Q

Folic Acid MOA

A

Converts the active form of folic acid after administration

33
Q

Indications for Folic Acid

A

Treatment of folic acid deficiency anemia, prophylaxis of folate deficiency, initial treatment of severe anemia from B12 deficiency

34
Q

AE of folic acid

A

none
