Which finding for a client with an arteriovenous fistula (AV Fistula) should the practical nurse (PN) report to the healthcare provider?
Descriptions of numbness and tingling in fingers distal to the AVF.
A loud and consistent bruit is auscultated at the AVF site.
Bruising at the AVF site is purple and green in color.
Radial pulse distal to AVF is absent and ulnar pulse is present.
The Correct Answer is A
The correct answer is choice A: Descriptions of numbness and tingling in fingers distal to the AVF.
Choice A rationale:
Descriptions of numbness and tingling in fingers distal to the arteriovenous fistula (AVF) suggest possible nerve compression or impaired blood flow, which are concerning findings. These symptoms could indicate reduced perfusion to the distal extremities and require immediate attention to prevent further complications.
Choice B rationale:
A loud and consistent bruit auscultated at the AVF site is an expected finding and indicates adequate blood flow through the fistula. A bruit is the sound of turbulent blood flow and is commonly heard over functional AV fistulas.
Choice C rationale:
Bruising at the AVF site is a common occurrence after the creation of the fistula. It is expected due to the surgical intervention and the manipulation of blood vessels. As long as the bruising is not severe or accompanied by other concerning symptoms, it does not need immediate reporting.
Choice D rationale:
The absence of the radial pulse distal to the AVF and the presence of the ulnar pulse are normal findings in a functioning AV fistula. The AV fistula diverts blood flow away from the radial artery, leading to a diminished pulse. This is not a cause for concern as long as the ulnar pulse is present, indicating adequate perfusion to the hand.

Correct Answer is A
Explanation
The correct answer is Choice A:
"Are you planning to obey the voices?.”. Choice A rationale:
The PN should ask the client if he plans to obey the voices because it helps assess the potential risk of harm to himself or others. If the client indicates an intention to follow the voices' commands to harm someone, it indicates a serious concern for safety and may require immediate intervention to protect the client and others.
Choice B rationale:
While asking if the client believes the voices are real is important for understanding the client's perception of the situation, it may not immediately address the risk of harm that the client or others might be facing.
Choice C rationale:
Asking if the client has taken any hallucinogens is relevant to explore possible substance- induced psychosis, but this question should be asked later in the assessment process. The priority is to assess immediate safety concerns related to the client's compliance with the voices' instructions.
Choice D rationale:
Inquiring about when the voices began is important, but it is not the most urgent question in this situation. Although the onset of the symptoms is relevant, addressing the potential for harmful actions should be prioritized.
Correct Answer is A
Explanation
A thready pulse is a weak and rapid pulse that is easily obliterated by light pressure. It indicates poor blood flow and perfusion and may be caused by conditions such as shock, dehydration, or hemorrhage.
The other options are not correct because:
B. A missing pulse is a pulse that is absent or cannot be detected, even with firm pressure. It indicates a complete blockage of blood flow, and may be caused by conditions such as arterial occlusion, embolism, or trauma.
C. Light pressure applied to pulse is not a documentation of the pulse quality, but a description of the technique used to palpate the pulse.
D. Pulse skips beats is a documentation of an irregular pulse rhythm, not a pulse volume. It indicates that the heart beats are unevenly spaced, and may be caused by conditions such as arrhythmia, stress, or caffeine intake.
