The nurse is assessing a patient’s arteriovenous (AV) fistula. Which finding provides evidence of its normal function?

Pulselessness.

Ecchymotic area.

Redness.

Enlarged vein.

Answer and Explanation

The Correct Answer is D

Choice A reason: Pulselessness is not a sign of normal AV fistula function; a palpable pulse should be present.
Choice B reason: An ecchymotic area suggests bruising and is not indicative of normal function.
Choice C reason: Redness may indicate inflammation or infection, not normal function.
Choice D reason: This is the correct choice. An enlarged vein is typical for an AV fistula and indicates good blood flow through the fistula.

Correct Answer is C

Explanation

Choice A reason: Applying a warm, moist pack is not the most appropriate action as it may increase swelling and does not address the underlying cause of the edema.

Choice B reason: While it is important to report significant changes to the healthcare provider, mild edema post-surgery can be expected and managed with elevation.

Choice C reason: Elevating the legs on pillows can help reduce edema by promoting venous return and decreasing swelling.

Choice D reason: Encouraging movement of the toes is beneficial for circulation and preventing stiffness, but it is not the primary intervention for edema. Elevation is more effective in this scenario.

A. Meningitis B. Family history C. Environmental toxins D. Mother had gestational diabetes

Correct Answer is A

Explanation

Choice A reason: Meningitis is an infection of the protective membranes covering the brain and spinal cord and is not typically listed as a risk factor for ADD/ADHD.

Choice B reason: A family history of ADD/ADHD is a known risk factor, as the disorder can have a genetic component.

Choice C reason: Exposure to environmental toxins, such as lead, is associated with an increased risk of developing ADD/ADHD.

Choice D reason: While maternal health issues like gestational diabetes can impact a child's development, they are not directly linked to ADD/ADHD as a risk factor in the same way as genetic or environmental factors. However, this choice is less incorrect than Choice A, as there is some evidence suggesting a potential association between gestational diabetes and developmental disorders.
