Which of the following is the most reliable early indicator of infection in a client with low WBC?

Fever

Chills

Tachycardia

Dyspnea

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is ["C","D"]

Explanation

Cardiovascular disease (CVD) is a significant risk factor for gout. This is because CVD often coexists with other conditions that can elevate uric acid levels, such as hypertension, obesity, and chronic kidney disease. Additionally, some medications used to treat CVD, such as thiazide diuretics, can also increase uric acid levels.

Research has shown that people with CVD have a 2-3 times higher risk of developing gout compared to those without CVD.

The mechanisms linking CVD and gout are complex and not fully understood, but they likely involve shared pathways of inflammation and endothelial dysfunction.

Choice D rationale:

Diuretic use, particularly thiazide diuretics, is a well-established risk factor for gout. These medications work by increasing the excretion of fluids and electrolytes from the body, which can also lead to a decrease in the excretion of uric acid.

This can result in a buildup of uric acid in the blood, which can then crystallize in joints and cause gout attacks.

The risk of gout associated with diuretic use is dose-dependent, meaning that higher doses of diuretics are associated with a higher risk of gout.

Choice A rationale:

Depression has not been consistently shown to be an independent risk factor for gout.
Some studies have suggested a possible link between depression and gout, but others have not found any association. More research is needed to clarify the relationship between these two conditions.

Choice B rationale:

Deep sleep deprivation has not been studied as a risk factor for gout.
There is currently no evidence to suggest that it is directly associated with an increased risk of developing the disease.

A. Develops an acute retroviral syndrome B. Has a CD4+ T lymphocyte level of less than 200 cells/mm C. Is capable of transmitting the virus to others D. Contracts HIV-specific antibodies A nurse is caring for a client who has been diagnosed as HIV positive.

Correct Answer is B

Explanation

Choice A rationale:
Acute retroviral syndrome (ARS) is an early stage of HIV infection that often presents with flu-like symptoms. It does not determine AIDS diagnosis.

Choice B rationale:
A CD4+ T lymphocyte level of less than 200 cells/mm is a defining criterion for AIDS diagnosis. This low count indicates a severely weakened immune system, leading to susceptibility to opportunistic infections and other AIDS-defining illnesses.

Choice C rationale:
A person with HIV can transmit the virus to others regardless of their CD4+ T cell count. Transmission risk is not a diagnostic criterion for AIDS.

Choice D rationale:
HIV-specific antibodies are produced by the immune system in response to HIV infection but their presence does not signify AIDS progression.
