Edema is a hallmark sign of SIADH caused by fluid shifts into the extracellular space.

Clinical manifestations include concentrated urine output and overhydration.

A patient is recovering from a lung resection because of malignant bronchogenic small cell carcinoma.

His serum sodium is 120 mEq/L and SIADH is suspected.

Which statement is accurate regarding SIADH?

Choice A rationale
Cervical cancer screening is recommended for individuals with a cervix starting at age 21, not necessarily for detecting colorectal cancer. It's an essential screening but irrelevant to middle-aged clients discussing colorectal cancer risk.
Choice B rationale
Lung cancer screening is mainly for people with a history of heavy smoking. Discussing lung cancer screening with a doctor is vital, but it does not address the early detection of colorectal cancer for average-risk individuals.
Choice C rationale
The previous recommendation was to start colorectal cancer screening at age 50. However, guidelines have updated, and this age is now considered outdated for average-risk individuals.
Choice D rationale
Colorectal cancer screening for everyone beginning at age 45 aligns with the latest American Cancer Society guidelines. This change reflects evidence showing the benefit of earlier screening to detect and prevent colorectal cancer in average-risk adults.

Rationale for correct condition: Mucositis is a common side effect of chemotherapy that causes inflammation and soreness in the mouth. The client reports mouth soreness and dry mucous membranes, consistent with mucositis. The presence of mild erythema on the oral mucosa also supports this diagnosis. Chemotherapy drugs such as vincristine and anthracycline are known to cause mucositis. Addressing mucositis early is crucial for maintaining the client’s nutrition and hydration.

Rationale for actions: Providing a soft sponge toothbrush helps maintain oral hygiene without causing further irritation. Maintaining the client’s diet ensures adequate nutrition, which is essential for healing mucositis. Pad the siderails of the bed is unnecessary in this scenario, as there's no indication of seizure risk. Requesting an antiemetic is irrelevant since the client has no significant nausea or vomiting.

Rationale for parameters: Monitoring weight loss helps assess the client’s nutritional status and the effectiveness of dietary interventions. Tracking intake and output ensures the client is adequately hydrated and that oral intake is sufficient. Edema monitoring is unnecessary, as there's no sign of fluid retention. Steatorrhea is not relevant in this context, as there's no indication of fat malabsorption.

Rationale for incorrect conditions: Diarrhea is not indicated as the client’s primary complaint is mouth soreness, not gastrointestinal upset. Angioedema is characterized by swelling and is not observed in the client. Seizures are not relevant here, as the client shows no neurological signs suggestive of seizure activity.
