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.”

Answer and Explanation

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 A

Explanation

Choice A Reason:

A red tag is used to label those who cannot survive without immediate treatment but who have a chance of survival. The child’s respiratory rate of 8/min, unresponsiveness to verbal commands, and groaning to painful stimuli indicate severe injuries that require urgent medical attention. Immediate intervention is necessary to address potential life-threatening conditions.

Choice B Reason:

A yellow tag is assigned to those who require observation and possible later re-triage. Their condition is stable for the moment, and they are not in immediate danger of death. Given the child’s critical condition, a yellow tag would not be appropriate as it suggests the child can wait for treatment, which is not the case here.

Choice C Reason:

A green tag is for the “walking wounded” who will need medical care at some point after more critical injuries have been treated. This tag is not suitable for the child in question, as their condition is far from minor and requires immediate attention.

Choice D Reason:

A black tag is used for the deceased or those whose injuries are so severe that they are not expected to survive despite receiving care. While the child’s condition is critical, they still have a chance of survival with immediate treatment, making a black tag inappropriate.

A. Expressive aphasia B. Poor impulse control C. Left hemiparesis D. Disorientation to place

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.
