Which of the following statements regarding diverticulosis of the colon is INCORRECT
Low-residue diet predisposes to colon diverticula
Diverticulum may become infected, causing diverticulitis
Ulceration of lining of diverticula caused by fecal material in the diverticula may cause bleeding from the ulcerated diverticulum
Diverticula predispose to colon carcinoma
The Correct Answer is D
A. Low-residue diet predisposes to colon diverticula: A low-fiber (low-residue) diet leads to harder stools and increased intraluminal pressure during bowel movements, which promotes the formation of diverticula, especially in the sigmoid colon.
B. Diverticulum may become infected, causing diverticulitis: When fecal material becomes trapped in a diverticulum, it can lead to localized infection and inflammation known as diverticulitis, which may cause pain, fever, or even abscess formation.
C. Ulceration of lining of diverticula caused by fecal material in the diverticula may cause bleeding from the ulcerated diverticulum: Trapped fecal matter can irritate and ulcerate the mucosal lining of diverticula, leading to localized bleeding, which may be seen as rectal bleeding or blood in the stool.
D. Diverticula predispose to colon carcinoma: Diverticulosis is not considered a premalignant condition. Although both conditions may coexist in older adults, the presence of diverticula does not increase the risk of colon cancer.

Correct Answer is C
Explanation
A. Changing an IV: This procedure involves standard precautions to avoid bloodborne infections, not primarily fecal-oral infections like hepatitis A. It is more relevant to viruses such as hepatitis B and C.
B. Disposing of food trays: While hygiene in food service is important, the nurse’s direct role in disposing of trays does not significantly contribute to HAV prevention. HAV is transmitted primarily through the fecal-oral route rather than leftover food on trays.
C. Emptying bed pans: Hepatitis A is spread via the fecal-oral route. Handling feces, especially without strict hand hygiene and appropriate protective equipment, poses a high risk for transmission. Therefore, careful attention is needed during this activity to prevent spread.
D. Taking an oral temperature: This involves mucosal contact but carries minimal risk of spreading hepatitis A, especially when using disposable covers and practicing standard precautions. It is not a primary concern for fecal-oral transmission.
Correct Answer is C
Explanation
A. Glomerulonephritis: This is an immune-mediated condition involving inflammation of the glomeruli and typically presents with proteinuria, hematuria, hypertension, and edema rather than urinary frequency, burning, or foul-smelling urine. The presence of E. coli and leukocytes does not support this diagnosis.
B. Kidney calculi: Kidney stones may present with flank pain, hematuria, and sometimes nausea or vomiting, but are not usually associated with urinary frequency, burning, or bacterial growth on urine culture. Randi’s symptoms point more toward an infectious etiology rather than a structural obstruction.
C. Lower UTI: cystitis (bladder infection) and possibly lower ureters: The burning, itching, frequent urination, and foul smell are classic signs of cystitis. The absence of flank pain and only a slightly elevated temperature further supports a lower tract infection rather than an upper one.
D. Upper UTI (pyelonephritis): Pyelonephritis typically presents with fever over 101°F, chills, nausea, vomiting, and significant costovertebral angle (CVA) tenderness or back/flank pain. Since Randi denies back pain and has only a mild temperature elevation, an upper UTI is unlikely.
