A nurse is teaching a newly licensed nurse about obtaining a fecal occult blood test from a client.
Which of the following information should the nurse include?
Collect two stool specimens from the same area of the stool.
Use toilet paper to transfer the stool specimen.
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
Choice A rationale
Collecting two stool specimens from the same area of the stool is incorrect because specimens should be taken from different areas to ensure a representative sample of the stool for testing.
Choice B rationale
Using toilet paper to transfer the stool specimen is not recommended as it can contaminate the sample and interfere with test results.
Choice C rationale
Applying four drops of developing solution to each stool specimen is incorrect. The usual procedure involves applying a specific number of drops as indicated by the test instructions, which may vary.
Choice D rationale
Waiting 30 seconds after applying the developing solution is correct. This waiting period allows the test to react and provide accurate results for the presence of occult blood.

Correct Answer is D
Explanation
Choice A rationale
Blood in the urine (hematuria) is not a typical finding in urinary retention. It may indicate other conditions such as infection, stones, or malignancy.
Choice B rationale
Cloudy urine is often a sign of infection, not typically associated with urinary retention. It can be caused by the presence of bacteria, white blood cells, or crystals.
Choice C rationale
Dark-colored urine can result from dehydration or certain foods and medications. It is not a specific finding of urinary retention.
Choice D rationale
Leakage of urine, also known as overflow incontinence, can occur in urinary retention. This happens when the bladder becomes overly full, and small amounts of urine leak out due to the pressure.
Correct Answer is D
Explanation
Choice D rationale
Intravenous (IV) administration has the fastest rate of absorption because the medication is delivered directly into the bloodstream, bypassing the absorption barriers of the digestive
system or muscle tissue. This ensures rapid onset of action.
Choice A rationale
Enteral administration involves the gastrointestinal tract, including oral and feeding tube methods. Absorption is slower as the medication passes through the digestive system before
entering the bloodstream.
Choice B rationale
Intramuscular (IM) administration involves injecting the medication into muscle tissue, where it is absorbed into the bloodstream. Absorption is quicker than enteral routes but slower
compared to IV administration.
Choice C rationale
Topical administration involves applying medication to the skin or mucous membranes. Absorption is generally slower and is intended for local or systemic effects, depending on the medication.
