A nurse is reinforcing teaching with a client who is prescribed ferrous sulfate. Which of the following statements by the client indicates an understanding of the teaching?

A. "I expect the color of my urine to be amber." Ferrous sulfate does not typically affect the color of urine. This statement indicates a misunderstanding of the medication's effects. B. "I will expect dark, tarry stools." Ferrous sulfate can cause stools to become dark or black, which is a common and expected side effect due to the iron content. This indicates the client understands a normal side effect of the medication. C. "I will not get as many infections." Ferrous sulfate is used to treat iron deficiency anemia and does not directly influence the incidence of infections. This indicates a lack of understanding of the medication’s purpose. D. "I will take extra care to protect against increased bruising." Increased bruising is not associated with ferrous sulfate. This indicates a misunderstanding of the medication's side effects.
