The nurse is participating in a health screening clinic and is preparing teaching materials about colorectal cancer. Which risk factor for colorectal cancer should the nurse include?

History of Roux-en-Y gastric bypass surgery

High fiber, low fat diet

Personal history of inflammatory bowel disease

Distant relative with colorectal cancer

Answer and Explanation

The Correct Answer is C

A. A history of Roux-en-Y gastric bypass surgery is not a direct risk factor for colorectal cancer; in some cases, it may reduce risk due to weight loss and dietary changes.
B. A high fiber, low fat diet is considered protective against colorectal cancer rather than a risk factor.
C. A personal history of inflammatory bowel disease, such as ulcerative colitis or Crohn's disease, significantly increases the risk for developing colorectal cancer due to chronic inflammation and cellular changes in the colon.
D. Having a distant relative with colorectal cancer may increase risk, but the personal history of inflammatory bowel disease is a stronger risk factor warranting emphasis in teaching.

Correct Answer is C

Explanation

A. Large tumors with distant metastasis may not respond well to radiation therapy, as the effectiveness diminishes when cancer spreads beyond the primary site.
B. While radiation can be effective for superficial cancers, it is most impactful when the cancer is localized.
C. Radiation therapy is most effective for localized cancers, where the treatment can target the tumor directly without affecting surrounding healthy tissues extensively.
D. Cancer spread to multiple sites in one organ complicates treatment and may reduce the efficacy of radiation therapy, as multiple targets may require different approaches.

A. Prone (supported) position B. Dorsal recumbent position C. Lateral recumbent D. Semi-Fowler's position

Correct Answer is D

Explanation

A. The prone position is not suitable post-craniotomy as it can increase intracranial pressure and may compromise respiratory function.
B. The dorsal recumbent position is not ideal for patients post-craniotomy, as it can hinder optimal intracranial pressure management.
C. The lateral recumbent position is generally avoided immediately after craniotomy to prevent pressure on the surgical site and ensure proper cerebral perfusion.
D. The Semi-Fowler's position helps reduce intracranial pressure, promotes venous drainage, and is generally recommended for post-operative care following a craniotomy.
