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
A client who has a chest tube and reports a pain level of 6 on a scale of 0 to 10. While pain management is important, this client is not in immediate life-threatening danger. Pain can be addressed after ensuring there are no urgent allergic reactions or other critical conditions.
Choice B Reason
A client who received parenteral cephalosporin and reports urticaria and edema. This is the correct choice. Urticaria (hives) and edema (swelling) can indicate an allergic reaction, which can progress to anaphylaxis, a life-threatening condition. Immediate assessment and intervention are required to prevent severe complications.
Choice C Reason
A client who is being admitted with bilateral stage 3 pressure injuries on both heels. While stage 3 pressure injuries are serious and require prompt attention, they do not pose an immediate life-threatening risk compared to a potential anaphylactic reaction.
Choice D Reason
A client who has a systemic infection and an oral temperature of 39.1°C (102.4°F). Although a systemic infection with a high fever is concerning and needs timely intervention, it is not as immediately life-threatening as a potential anaphylactic reaction.
Correct Answer is A
Explanation
Choice A Reason
Expressive aphasia is a common symptom of a left-hemisphere stroke. This condition, also known as Broca’s aphasia, affects the ability to produce language, making it difficult for the patient to speak fluently. The patient may understand speech but struggle to form coherent sentences, often speaking in short, choppy phrases.
Choice B Reason
Poor impulse control is more commonly associated with right-hemisphere strokes. The right hemisphere of the brain is responsible for controlling impulsive behavior and emotional regulation. Therefore, this symptom is less likely to be observed in a patient with a left-hemisphere stroke.
Choice C Reason
Left hemiparesis refers to weakness on the left side of the body. Since the left hemisphere of the brain controls the right side of the body, a left-hemisphere stroke typically results in right-sided weakness or paralysis. Therefore, left hemiparesis is not a typical finding in this scenario.
Choice D Reason
Disorientation to place can occur after a stroke, but it is not specifically associated with left-hemisphere strokes. Disorientation is a general symptom that can result from various types of brain injuries and is not exclusive to strokes affecting the left hemisphere.
