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 B
Explanation
Choice A rationale:
Asking the client to describe the intensity of the eye pain using the numerical pain scale is not the most relevant action in this situation. The client's statement indicates a misconception about the purpose of pilocarpine eye drops, so addressing this misunderstanding should be the focus.
Choice B rationale:
Reminding the client that the action of the eye drops is to decrease internal eye pressure is the appropriate action. Pilocarpine eye drops are used to treat glaucoma by reducing intraocular pressure, not to anesthetize the eye.
Choice C rationale:
Documenting in the chart that the client understands the action and use of the eye drops might be necessary but should not be the first action taken. The priority is to correct the client's misunderstanding about the eye drops.
Choice D rationale:
Clarifying with the client that eye pain in glaucoma is uncommon, so drops are rarely needed, is not accurate. While eye pain might not be a common symptom of glaucoma, pilocarpine eye drops are specifically used to manage intraocular pressure and are not intended to address eye pain.
Correct Answer is B
Explanation
The correct answer is choice B: Monitor the client's hearing. Choice A rationale:
Observing the skin for a rash is not relevant to assessing for signs of ototoxicity. Aminoglycosides can cause skin reactions, but this is not a specific sign of ototoxicity.
Choice B rationale:
Monitoring the client's hearing is essential when administering aminoglycosides because these medications can cause ototoxicity, which is damage to the inner ear and auditory nerve leading to hearing loss or tinnitus. Regular hearing assessments can help detect any changes in hearing and prompt appropriate interventions.
Choice C rationale:
Measuring the urinary output is not directly related to assessing for ototoxicity.
Aminoglycosides can cause kidney toxicity, but this is a separate concern from ototoxicity. Choice D rationale:
Checking for changes in vision is not specifically associated with aminoglycoside administration. Vision changes are not a common side effect of these medications, so it would not be a primary assessment in this situation.
