A nurse is reinforcing teaching with a client who has a prescription for ferrous sulfate elixir.

Which of the following statements by the client indicates an understanding of the teaching?

Blurred vision in the third trimester of pregnancy can be a potential sign of preeclampsia, a serious condition characterized by high blood pressure and organ damage.

Shortness of breath when climbing stairs is a common symptom in the third trimester as the growing uterus puts pressure on the diaphragm and limits lung expansion. While it is important to monitor the client's respiratory status, it is not an immediate cause for concern unless accompanied by severe or persistent shortness of breath.

Leukorrhea refers to an increase in vaginal discharge during pregnancy, which is a normal physiological change. It is typically white or clear and does not indicate any immediate problems unless it is accompanied by other symptoms such as itching, foul odor, or irritation.

Numbness or tingling in the fingers during pregnancy can be caused by pressure on nerves due to fluid retention or changes in the body's circulation. While it can be uncomfortable, it is not typically considered an urgent issue unless it is severe, persistent, or accompanied by other concerning symptoms.

Giving change-of-shift report to a nurse outside the client's room helps to maintain client confidentiality. By discussing sensitive client information in a private and secure area, such as a designated report room or a location where other clients or visitors cannot overhear, the nurse ensures that the client's personal and medical information is not disclosed to unauthorized individuals.

Writing a client's diagnosis on the message board in the client's room can potentially expose sensitive medical information to anyone who enters the room, including visitors or other healthcare providers who are not directly involved in the client's care.

Discussing a client's prognosis with an assistive personnel who is caring for the client may violate the principle of need-to-know confidentiality. While it is important for healthcare team members to collaborate and communicate about client care, sensitive information should only be shared on a need-to-know basis.

Discarding worksheets containing client information in a wastebasket without proper shredding or disposal methods can potentially expose client information to unauthorized individuals who may come across the discarded documents. Proper procedures for document disposal, such as shredding or using secure disposal containers, should be followed to protect client confidentiality.
