protected from heat, sunlight, and strong fluorescent light; should not be stored in close proximity to volatile chemicals.15.What factors can cause a failure of the expected control results to occur on a guaiac slide test?Use of outdated slides or developing solution; an error in technique; subjection of the slides to heat, sunlight, strong fluorescent light, or volatile chemicals.16.List the advantages of the fecal immunochemical test (FIT) compared with the guaiac slide test.FIT is more sensitive to the presence of lower gastrointestinal bleeding; FIT is not affected by drugs or food and therefore does not require medication and dietary restrictions; FIT has fewer false-positive test results.17.How does a fecal DNA test function to detect colorectal cancer?Uses DNA technology to detect abnormal cells that are shed into the stool from cancerous growths or colorectal polyps.18.What is the purpose of performing a sigmoidoscopy?Following a positive fecal occult blood test to determine the source and cause of the bleeding; to evaluate patient symptoms related to the colon such as lower abdominal pain, diarrhea, or constipation; to detect the presence of lesions, polyps, hemorrhoids, fissures, infection, and inflammation.19.Describe the following patient preparation required for a sigmoidoscopy:a.The day before the procedure and continuing until the examination is completed:?Do not consume any solid food or milk products; consume only gelatin (Jell-O) or popsicles (except purple or red, which could be mistaken for blood in the colon); drink only clear liquids (water, apple juice, sport drinks [e.g., Gatorade], soft drinks, clear broth); do not drink alcohol; coffee or tea is permitted with no milk or cream.b.The evening before the procedure:Drink the following laxative between 5 p.m. and 7 p.m.: one 10-ounce bottle of Magnesium Citrate; continue drinking plenty of clear liquids throughout the evening.c.The day of the procedure:?You may continue drinking clear liquids until 4 hours before the procedure; 2 hours before the examination: Insert one Fleet’s enema rectally following the package instructions; 1 hour before the procedure: Insert another Fleet’s enema.20.What is the purpose of the digital rectal examination (DRE)?To palpate the rectum for the presence of tenderness, hemorrhoids, polyps, or tumors; also to relax the sphincter muscles and to prepare the patient for the insertion of the endoscope.21.What is the purpose of insufflating air into the colon during a sigmoidoscopy?To distend the lumen of the colon for better visualization.22.What is the purpose of suctioning during sigmoidoscopy?To remove secretions such as mucus, blood, and liquid feces, which interfere with proper visualization of the intestinal mucosa.23.What is the recommended position of the patient during flexible fiberoptic sigmoidoscopy?Sims’ position.24.How can the medical assistant help the patient relax during the sigmoidoscopy?By telling the patient to breathe slowly and deeply through the mouth.25.What parts of the colon are viewed during a colonoscopy?Sigmoid colon, descending colon, transverse colon, and ascending colon.26.What is the purpose of a full bowel preparation before a colonoscopy?To empty the colon of fecal material that can interfere with good visualization of the wall of the colon, making it?difficult to detect abnormalities.27.How should a patient consume the liquid laxative solution when preparing the bowel for a colonoscopy?Drink one 8-ounce glass of the liquid laxative solution every 10 to 15 minutes until 2 quarts (eight 8-ounce glasses) have been consumed.28.Where is the prostate gland located?The prostate gland surrounds the urethra and is located just below the bladder and in front of the rectum.29.What are the symptoms of prostate cancer?Difficulty in urinating; weak or interrupted urinary flow; pain or burning during urination; frequent urination; blood in the urine; pain in the lower back, pelvis, or upper thighs.30.How is the digital rectal examination used for the early detection of prostate cancer?Normally, the prostate gland should feel soft, whereas malignant tissue is firm and hard.31.What conditions can cause an elevated PSA level?Prostate cancer, benign prostatic hyperplasia, and prostatitis.32.What is the PSA level for each of the following:a.Normal range 0 to 4?ng/ml.b.Slightly elevated range 4 to 10?ng/ml.c.Moderately elevated range 10 to 20?ng/ml.d.Highly elevated Greater than 20?ng/ml.33.What patient preparation is required for a PSA test?Engage in normal activity for 2 days before the test (avoid vigorous exercise); do not have sexual intercourse for?2?days before the test.34.What tests may be ordered by the physician if the patient has positive prostate screening results?Transrectal ultrasound, biopsy of the prostate gland, bone scan, and CT scan.35.What is the definition of the term screening?The process of testing an individual to detect a disease in that individual who is not yet experiencing symptoms of?that disease.36.What is the American Cancer Society recommendation for the PSA test and the DRE?Health care providers discuss the potential benefits and limitations of prostate screening with men older than 50?years of age; following this discussion, the PSA test and the DRE should be offered annually to men 50 years and older who are at average risk for prostate cancer and have at least a 20-year life expectancy. Those men who indicate a preference for testing should be tested.37.When does testicular cancer most commonly occur?Between the ages of 15 and 34.38.When is the best time for a male to perform a testicular self-examination (TSE) and why?After taking a warm bath or shower. Heat allows the scrotal skin to relax and become soft, making it easier to palpate the underlying testicular tissues.39.What are the risk factors for testicular cancer?History of undescended testicles, family history of testicular cancer, cancer of the other testicle, Caucasian race.40.What is the most common sign of testicular cancer?A small, hard, painless lump located on the front or side of the testicle.Critical Thinking ActivitiesA.
