A nurse is teaching a patient to obtain a specimen for fecal occult blood testing using the fecal immunochemical testing (FIT) at home. How does the nurse instruct the patient to collect the specimen?
Get three fecal smears from one bowel-movement.
Collect one fecal smear from three separate bowel movements,
Obtain one fecal smear from an early morning bowel movement.
Get three fecal smears when you see blood in your bowel movement.
The Correct Answer is B
A. Get three fecal smears from one bowel movement. FIT only requires one sample per bowel movement, but it is best to test multiple separate bowel movements for accuracy.
B. Collect one fecal smear from three separate bowel movements. FIT testing detects blood proteins using antibodies, and blood presence in stool can be intermittent. Collecting samples from different days increases accuracy.
C. Obtain one fecal smear from an early morning bowel movement. Time of day does not matter, but multiple samples from different bowel movements are preferred.
D. Get three fecal smears when you see blood in your bowel movement. FIT is meant to detect hidden (occult) blood that is not visible.

Correct Answer is B
Explanation
A. Uremia is a buildup of waste products in the blood due to kidney failure, leading to confusion, nausea, and other systemic symptoms rather than acute urinary incontinence.
B. Cystitis (bladder infection) causes inflammation, urgency, frequency, dysuria, and can lead to sudden incontinence in older adults, particularly those with weakened immune systems or cognitive impairment.
C. Diverticulitis is an inflammation of the colon’s diverticula, leading to abdominal pain and bowel disturbances, not urinary incontinence.
D. Nephrosclerosis is a chronic condition involving kidney damage due to hypertension or diabetes, which may lead to kidney failure but does not directly cause acute urinary incontinence.
Correct Answer is C
Explanation
A. Functional urinary incontinence: This occurs when mobility or cognitive impairments prevent the client from reaching the toilet in time. Since this client has a strong urge to void, functional incontinence is not the best fit.
B. Urinary retention: Urinary retention is the inability to empty the bladder completely, often leading to overflow incontinence. However, this client experiences urgency and leakage, not retention.
C. Urge urinary incontinence: This occurs when a strong, sudden urge to urinate leads to involuntary leakage before reaching the toilet. It is often due to overactive bladder or neurological issues.
D. Impaired skin integrity: While prolonged incontinence can lead to skin breakdown, the primary diagnosis should address the cause of incontinence rather than a secondary complication.
