A nurse is caring for a patient who has rheumatoid arthritis. Which of the following laboratory tests are used to diagnose the disease? (Select all that apply)
Antinuclear antibody (ANA) titer
BUN
Urinalysis
Erythrocyte sedimentation rate (ESR)
White blood cell count
Correct Answer : A,D,E
Choice A rationale:
Antinuclear antibody (ANA) titer is a blood test that detects the presence of antinuclear antibodies, which are autoantibodies that target the body's own tissues. These antibodies are often present in people with autoimmune diseases, including rheumatoid arthritis.
While a positive ANA test does not definitively diagnose rheumatoid arthritis, it can support a diagnosis when considered alongside other clinical findings and laboratory tests.
Choice B rationale:
Blood urea nitrogen (BUN) is a blood test that measures the amount of urea nitrogen in the blood. Urea nitrogen is a waste product that is produced when the body breaks down proteins.
BUN levels can be elevated in people with kidney disease, dehydration, or certain other medical conditions. However, BUN is not specifically used to diagnose rheumatoid arthritis.
Choice C rationale:
Urinalysis is a test that examines the urine for various substances, including cells, bacteria, and chemicals.
It can be used to diagnose a variety of conditions, including urinary tract infections, kidney disease, and diabetes. However, urinalysis is not typically used to diagnose rheumatoid arthritis.
Choice D rationale:
Erythrocyte sedimentation rate (ESR) is a blood test that measures how quickly red blood cells settle at the bottom of a test tube.
A high ESR can indicate inflammation in the body.
ESR is often elevated in people with rheumatoid arthritis, as it is a marker of inflammation.
Choice E rationale:
White blood cell count (WBC) is a blood test that measures the number of white blood cells in the blood. White blood cells are part of the immune system and help fight infection.
A high WBC count can indicate an infection or inflammation.
WBC count can be elevated in people with rheumatoid arthritis, as it is a marker of inflammation.

Correct Answer is A
Explanation
The correct answer is choice A.
Choice A rationale: Assisting the patient to the bathroom every 2 hours is a fixed schedule that doesn't allow for individual variations in bladder function. A bladder-training program should encourage the patient to recognize and respond to their own urge to urinate, promoting self-reliance and bladder control.
Choice B rationale: Offering the opportunity to urinate before bathing is a good practice to prevent accidents and promote comfort. It also helps to reduce the risk of urinary tract infections.
Choice C rationale: Encouraging the patient to urinate when they feel the urge is a key component of bladder training. It helps the patient to develop bladder control and reduce the frequency of accidents.
Correct Answer is A
Explanation
Choice A rationale:
Urinary retention is a condition where the bladder doesn’t empty all the way or at all when you urinate. This can lead to leakage of urine, as the bladder is overfilled and may result in small amounts of urine escaping. This symptom is often associated with urinary retention and is therefore a likely finding in a client with this condition.
Choice B rationale:
Dark-colored urine is not typically a direct symptom of urinary retention. It can be a sign of dehydration, certain dietary factors, or a side effect of some medications. While it’s possible for a person with urinary retention to have dark-colored urine, it’s not a specific or direct symptom of the condition.
Cloudy urine can be a sign of a urinary tract infection (UTI), which can occur as a complication of urinary retention. However, it’s not a direct symptom of urinary retention itself. A nurse would not necessarily expect to see cloudy urine in a client with urinary retention unless a UTI or another complication was present.
Choice D rationale:
Blood in the urine, or hematuria, is not a typical symptom of urinary retention. It can be a sign of various conditions, including UTIs, kidney stones, or more serious conditions like bladder or kidney disease. While it’s possible for a person with urinary retention to have blood in their urine, it’s not a direct symptom of the condition.
