A nurse on a medical-surgical unit is planning to delegate tasks to an adult volunteer. Which of the following tasks should the charge nurse avoid assigning to the volunteer?
Delivering meal trays to clients in their rooms
Helping observe postoperative clients who are confused
Assisting ambulatory clients with meals
Delivering mail
The Correct Answer is B
Choice A rationale:
Delivering meal trays to clients in their rooms is a simple task that does not require any specialized skills or knowledge. Volunteers can be safely assigned this task, as it does not involve any direct patient care or decision-making.
Choice B rationale:
Observing postoperative clients who are confused requires a higher level of skill and knowledge than delivering meal trays. Volunteers are not typically trained to assess and monitor patients for changes in their condition, and they may not be able to recognize and respond to potential emergencies. This task is best assigned to a licensed nurse or other qualified healthcare professional.
Choice C rationale:
Assisting ambulatory clients with meals is another task that can be safely assigned to volunteers. This task involves helping patients with simple activities such as opening food containers and cutting food. Volunteers can be trained to perform these tasks safely and effectively.
Choice D rationale:
Delivering mail is a simple task that does not require any specialized skills or knowledge. Volunteers can be safely assigned this task, as it does not involve any direct patient care or decision-making.

Correct Answer is ["A","D","E"]
Explanation
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
Choice A rationale:
Fever is the most reliable early indicator of infection in a client with low WBC because it is a direct physiologic response to the presence of pathogens. When the body detects an infection, it releases pyrogens, which act on the hypothalamus to raise the body's temperature. This elevated temperature helps to create an environment that is less hospitable to bacteria and viruses, and it also stimulates the immune system to fight the infection.
In clients with low WBC, the immune system is already compromised, so the fever response may be even more pronounced. It's important to note that even a slight elevation in temperature (as low as 100.4°F or 38°C) can be significant in these clients.
Choice B rationale:
Chills can also be a sign of infection, but they are not as specific as fever. Chills can occur for other reasons, such as exposure to cold or anxiety.
Choice C rationale:
Tachycardia, or increased heart rate, can also be a sign of infection, but it is not as reliable as fever. Tachycardia can occur for other reasons, such as dehydration, pain, or anxiety.
Choice D rationale:
Dyspnea, or shortness of breath, is not a typical early sign of infection. It is more likely to occur in later stages of infection, when the infection has spread to the lungs.
