A nurse is reinforcing teaching with a client about preventing the transmission of hepatitis A. The nurse should identify that hepatitis A is transmitted by which of the following routes?

Choice A reason: This is a normal finding, not an indication of breast cancer. Lumps that are mobile and tender upon palpation prior to a menstrual period are usually benign and related to hormonal changes.

Choice B reason: This is a normal finding, not an indication of breast cancer. Multiple round masses that are tender and found in both breasts are usually benign and related to fibrocystic breast changes.

Choice C reason: This is a normal finding, not an indication of breast cancer. Bilaterally darkened areolas are usually benign and related to genetic factors, pregnancy, or aging.

Choice D reason: This is an abnormal finding, and an indication of breast cancer. A nontender hard lump that is palpated in one breast is usually malignant and related to abnormal cell growth.

Choice A reason: This is an incorrect instruction, because the client does not need to remain NPO, or nothing by mouth, before a standard EEG. The client can eat and drink normally, unless the provider instructs otherwise.

Choice B reason: This is an incorrect instruction, because the client should not take a sedative, or any other medication that can affect the brain activity, before a standard EEG. The client should take the usual medications, unless the provider instructs otherwise.

Choice C reason: This is the correct instruction, because the client should thoroughly shampoo hair prior to the EEG. The client should wash the hair with a mild shampoo and rinse well, without using any conditioner, gel, spray, or other hair products. This can help remove any oil, dirt, or residue that can interfere with the placement and function of the electrodes.

Choice D reason: This is an incorrect instruction, because the client should not take an additional dose of anticonvulsant medication before a standard EEG. The client should take the regular dose of anticonvulsant medication, unless the provider instructs otherwise.
