A nurse is reinforcing teaching with a newly licensed nurse about obtaining a fecal occult blood test from a client. Which of the following information should the nurse include?
Use toilet paper to transfer the stool specimen.
Collect two stool specimens from the same area of the stool.
Apply four drops of developing solution to each stool specimen.
Wait 30 seconds after applying the developing solution to obtain the results.
The Correct Answer is D
A. Use toilet paper to transfer the stool specimen: Incorrect. Toilet paper is not sterile and can contaminate the sample. Use a clean applicator or stick.
B. Collect two stool specimens from the same area of the stool: Incorrect. Collect specimens from two different areas to increase accuracy.
C. Apply four drops of developing solution to each stool specimen: Incorrect. The number of drops may vary depending on the test kit instructions.
D. Wait 30 seconds after applying the developing solution to obtain the results: This allows the solution to react with any blood present in the stool, providing accurate results.

Correct Answer is C
Explanation
A. Immediately before meals: Although the gastrocolic reflex is stimulated after eating, taking the client immediately before meals does not align with the natural defecation reflex.
B. Every 2 hr while the patient is awake: This does not consider the client’s natural bowel patterns and may lead to frustration or noncompliance.
C. When the client has the urge to defecate: Bowel training is most effective when timed to coincide with the client's natural urge to defecate, promoting a routine and reducing the risk of constipation or incontinence.
D. After the client feels abdominal cramping: Cramping could indicate discomfort from gas or constipation, not necessarily the optimal time for defecation.
Correct Answer is B
Explanation
A. Decrease in systolic blood pressure: Incorrect. Aging often results in increased systolic blood pressure due to arterial stiffening, not dehydration risk.
B. Decrease in kidney function: Aging decreases kidney function, reducing the ability to concentrate urine and regulate fluid balance, increasing the risk of dehydration.
C. Increase in percentage of body water: Incorrect. Aging is associated with a decrease, not an increase, in body water, contributing to dehydration risk.
D. Increase in saliva production: Incorrect. Aging leads to reduced saliva production, not an increase, but this is not directly related to dehydration.
