A nurse is reviewing the medical record of a client to identify risk factors for colorectal cancer. The nurse should identify which of the following findings as increasing the client's risk?

History of Crohn's disease

Diet high in fiber

Age 46 years

BMI of 24

Answer and Explanation

The Correct Answer is A

A history of inflammatory bowel disease, such as Crohn's disease or ulcerative colitis, is a risk factor for colorectal cancer . These conditions cause chronic inflammation and damage to the cells lining the colon and rectum, which may increase the likelihood of DNA mutations and cancer development. A diet high in fiber may help lower the risk of colorectal cancer by promoting regular bowel movements and reducing exposure to toxins. Age 46 years is not a significant risk factor, as most cases of colorectal cancer occur in people older than 50. BMI of 24 is within the normal range and does not indicate obesity, which is another risk factor for colorectal cancer.

Correct Answer is D

Explanation

Positive end-expiratory pressure (PEEP) is a mode of mechanical ventilation that maintains a positive pressure in the airways at the end of expiration, preventing alveolar collapse and improving oxygenation. PEEP does not affect tidal volume, inspiratory pressure, or ventilation rate, which are determined by other ventilator settings.

A. Check the client's gag reflex. B. Inform the client they might experience a low-grade fever. C. Provide the client with sips of water. D. Instruct the client to report bleeding.

Correct Answer is A

Explanation

The nurse should assess the client's gag reflex before allowing oral intake to prevent aspiration. The client's throat may be numb after a bronchoscopy, which is a procedure that uses a thin tube with a camera and light to examine the lungs and airways . The other actions are important but not the priority.
