A patient is receiving hormone therapy for treatment of breast cancer.
The nurse should inform the patient that she is at high risk for the development of which of these serious effects?

Choice A rationale

Suggesting the client avoid eating until hungry is generally not the best intervention for chemotherapy-induced nausea and loss of appetite. Prolonged fasting can worsen malnutrition, lead to energy deficits, and potentially exacerbate nausea due to an empty stomach, hindering recovery and treatment tolerance.

Choice B rationale

Encouraging the client to eat three large meals per day is often counterproductive during chemotherapy when nausea and appetite loss are prevalent. Large meals can overwhelm the digestive system, increase feelings of fullness, and trigger or worsen nausea and vomiting, leading to reduced intake.

Choice C rationale

Advising the client to increase their intake of fatty foods is generally not recommended for chemotherapy-induced nausea. Fatty foods are more difficult to digest, can delay gastric emptying, and are more likely to exacerbate nausea, bloating, and discomfort in a compromised digestive system.

Choice D rationale

Offering small, frequent meals that are easy to digest is the most effective intervention. This approach minimizes gastric distention, reduces the likelihood of triggering nausea, and allows for consistent nutrient intake. Easily digestible foods like crackers, toast, and clear broths are preferred, maintaining hydration.

Choice A rationale

A biopsy involves the surgical removal of tissue or cells for microscopic examination by a pathologist. This is considered the gold standard for cancer diagnosis because it allows for direct visualization of cellular morphology, architectural patterns, and specific cellular markers, providing definitive evidence of malignant transformation and tumor type, which other imaging or blood tests cannot conclusively provide.

Choice B rationale

While a biopsy can differentiate between inflammatory processes, benign growths, and malignant tumors, its primary purpose in the context of suspected cancer is not to determine if an infection is present. Infections are typically diagnosed through microbial cultures, serological tests, or direct antigen detection, not primarily through tissue biopsy for cancer.

Choice C rationale

A biopsy from the primary suspected site of cancer is used to confirm the initial diagnosis and characterize the primary tumor. While biopsies of suspicious secondary lesions can confirm metastasis, the initial diagnostic biopsy is not primarily aimed at confirming metastasis but rather at establishing the presence and type of primary cancer. Metastasis is often assessed through imaging studies.

Choice D rationale

While advancements in molecular pathology allow for genetic analysis of biopsy samples to detect specific mutations associated with cancer (e.g., for targeted therapies), the fundamental and initial reason for a biopsy in a possible cancer diagnosis is to determine the presence of abnormal, cancerous cells through histological examination, not solely for genetic mutation detection.
