Answer and Explanation

The Correct Answer is D

A.   Probiotics do not typically interact with warfarin. They generally affect gut health and are not known to have significant effects on blood clotting mechanisms.
B.   Coenzyme Q10 has minimal effects on warfarin metabolism. It is mainly involved in cellular energy production and does not significantly alter coagulation.
C.   Valerian primarily affects the central nervous system and has no significant interaction with warfarin. It is mainly used for its sedative properties and does not interfere with blood thinning.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"A"},"D":{"answers":"A"},"E":{"answers":"A"}}

Explanation

A. Antacids can interfere with the absorption of ferrous sulfate, reducing its effectiveness. The client should avoid taking antacids concurrently with the iron supplement.
B. Black stools are a common and expected side effect of taking iron supplements. This is generally not a cause for concern and does not require notifying the provider unless accompanied by other symptoms such as pain or blood in the stool.

C. Liquid forms of iron supplements can stain teeth. Rinsing the mouth after taking the medication can help prevent this staining. Even if taking a tablet, this practice can be a good habit to avoid any residual taste.
D. Vitamin C, which is present in orange juice, can enhance the absorption of iron from the gastrointestinal tract, making the iron supplement more effective.
E. Iron supplements are best absorbed on an empty stomach. However, if the client experiences gastrointestinal upset, it can be taken with a small amount of food, but avoiding dairy products and antacids is important.
