Correct Answer: C

Rationale: Although presymptomatic testing for genetic disorders allows patients to take action (such as mastectomy) to prevent the development of some genetically caused disorders, patients also need to consider that test results in their medical record may affect insurance, employability, etc. Telling a patient that a decision about mastectomy should be made before testing implies that the nurse has made a judgment about what the patient should do if the test is positive. Although most breast cancers are not related to BRCA gene mutations, the patient with a BRCA gene mutation has a markedly increased risk for breast cancer.

Correct Answer: C

Rationale: The correct answer is C. Clients with liver cirrhosis should avoid acetaminophen because it can cause further liver damage. Acetaminophen is metabolized in the liver, and in individuals with liver disease, it can lead to liver toxicity. Therefore, clients with liver cirrhosis should use alternative pain medications that do not affect the liver, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or opioids as prescribed by their healthcare provider.

Correct Answer: C

Rationale: The correct answer is C: Deep, rapid respirations (Kussmaul breathing). This is a sign of severe acidosis commonly seen in diabetic ketoacidosis (DKA) and requires immediate intervention. Kussmaul breathing helps to compensate for the metabolic acidosis by blowing off carbon dioxide. Prompt intervention is necessary to prevent further deterioration and potential respiratory failure.

Correct Answer: A

Rationale: The correct response is A: 'The cancer involves only the cervix.' In staging, 'Tis' indicates cancer in situ, which means it is localized to the cervix and not invasive at this time. The differentiation of cancer cells is not part of clinical staging. Since the cancer is in situ, its origin is the cervix. Further testing is not required as the cancer has not spread beyond the cervix.

Correct Answer: C

Rationale: When a patient with cervical cancer is receiving external-beam radiation, the radiation to the abdomen can affect organs in its path, such as the bowel, leading to complications like frequent diarrhea. Cleaning the perianal area carefully after each bowel movement is crucial to decrease the risk of skin breakdown and infection. Testing stools for blood is not necessary since inflammation associated with radiation may lead to occult blood in stools. Maintaining a low-residue diet is actually recommended to prevent bowel irritation. Radiation to the abdomen does not cause stomatitis, so inspecting the mouth and throat for thrush is not directly related to the effects of external-beam radiation in this context.
