A nurse is teaching a client about fecal occult blood testing (FOBT) for the screening of colorectal cancer. Which of the following statements should the nurse include in the teaching?
“Your provider will use stool from your digital rectal examination to perform the test.”
“Your provider will prescribe a stimulant laxative prior to the procedure to evacuate the bowel.”
“You should begin annual fecal occult blood testing for colorectal cancer screening at 40 years old.”
“You should avoid taking corticosteroids prior to testing.”
The Correct Answer is D
Choice A Reason
“Your provider will use stool from your digital rectal examination to perform the test.” This statement is incorrect. For fecal occult blood testing, stool samples are typically collected at home using a special kit provided by the healthcare provider. The samples are then sent to a lab for analysis. Using stool from a digital rectal examination is not the standard procedure for FOBT.
Choice B Reason
“Your provider will prescribe a stimulant laxative prior to the procedure to evacuate the bowel.” This statement is incorrect. Stimulant laxatives are not typically prescribed before an FOBT. The test requires a small sample of stool, and using a laxative could interfere with the results. Patients are usually advised to follow specific dietary and medication guidelines to avoid false positives or negatives.
Choice C Reason
“You should begin annual fecal occult blood testing for colorectal cancer screening at 40 years old.” This statement is incorrect. Current guidelines recommend starting colorectal cancer screening, including FOBT, at age 45 for individuals at average risk. Screening may start earlier for those with a higher risk, such as a family history of colorectal cancer.
Choice D Reason
“You should avoid taking corticosteroids prior to testing.” This is the correct statement. Corticosteroids can cause gastrointestinal irritation and bleeding, which may lead to false-positive results in fecal occult blood tests. Therefore, it is important to avoid these medications before testing.

Correct Answer is B
Explanation
Choice A Reason
4g sodium diet. While reducing sodium intake is important for managing chronic kidney disease (CKD), a specific 4g sodium diet is not typically prescribed. Instead, patients are generally advised to limit sodium intake to less than 2,300 milligrams per day to help control blood pressure and reduce fluid retention.
Choice B Reason
Potassium-restricted diet. This is the correct intervention. Patients with CKD often have difficulty excreting potassium, leading to hyperkalemia, which can be dangerous. Therefore, a potassium-restricted diet is commonly recommended to maintain normal serum potassium levels.
Choice C Reason
High-phosphorus diet. This statement is incorrect. Patients with CKD are usually advised to limit phosphorus intake because their kidneys cannot effectively excrete phosphorus, leading to hyperphosphatemia. High phosphorus levels can cause bone and cardiovascular problems.
Choice D Reason
High-protein diet. This statement is incorrect. While protein is essential, excessive protein intake can increase the workload on the kidneys. Patients with CKD are often advised to follow a moderate protein diet to reduce the production of waste products that the kidneys need to filter.
Correct Answer is C
Explanation
Choice A Reason:
Taking aspirin is generally not recommended for pain management in polycystic kidney disease (PKD) patients. Aspirin can cause gastrointestinal bleeding and may affect kidney function, which is already compromised in PKD patients. Instead, acetaminophen is often recommended for pain relief.
Choice B Reason:
Reducing dietary fiber intake is not typically advised for PKD patients. In fact, a balanced diet with adequate fiber is important for overall health and can help manage symptoms such as constipation, which can be a concern for PKD patients.
Choice C Reason:
Applying dry heat to the abdomen can help alleviate pain associated with PKD. Heat therapy can relax muscles and reduce discomfort caused by the enlarged kidneys and cysts. This non-pharmacological approach is safe and can be effective in managing pain.
Choice D Reason:
Checking weight once per week is not sufficient for PKD patients. Regular monitoring of weight is important to detect fluid retention and other complications. It is generally recommended to check weight more frequently, such as daily, to promptly identify any significant changes.
