Correct Answer: D

Rationale: During a vision exam, the confrontation technique is used to assess peripheral vision. By sitting facing the client and moving an object inward from the periphery while looking directly at the client's face, the nurse allows the client to indicate when the object enters the visual field. This method helps in determining the extent of the client's peripheral vision accurately. Choices A, B, and C are incorrect as they do not describe the appropriate method for using the confrontation technique during a vision exam. Choice A involves using an ophthalmoscope to observe pupil constriction, choice B involves testing the peripheral field of vision without the confrontation technique, and choice C describes the Snellen eye chart test for visual acuity, which is not related to the confrontation technique.

Correct Answer: A

Rationale: After reviewing the expected outcomes identified in the plan of care, the nurse's next step should be to determine if these outcomes were realistic. This assessment helps in understanding if the goals set were achievable and appropriate for the client's condition before proceeding to compare them with current client data or modifying nursing interventions. By verifying the realism of the expected outcomes, the nurse ensures a solid foundation for further evaluation and adjustment of the care plan. Option B is incorrect because obtaining current client data comes after assessing the realism of the expected outcomes. Option C is incorrect because modifying nursing interventions should be based on the assessment of the expected outcomes' realism. Option D is incorrect as reviewing professional standards of care is important but not the immediate next step after assessing the expected outcomes' realism.

Correct Answer: D

Rationale: The most crucial assessment for the nurse to make after hemodialysis in a client with chronic renal failure is to check the client's fistula for bruit and thrill (D). This assessment is essential to ensure the patency of the fistula and adequate blood flow. Auscultating lung sounds (A), assessing blood pressure (B), and monitoring weight (C) are important assessments but are secondary to evaluating the fistula. Checking the fistula is vital as it directly impacts the effectiveness of the client's dialysis treatment and the patency of the vascular access, ensuring successful dialysis sessions.

Correct Answer: B

Rationale: In the scenario described, the correct action after a needle stick injury is to discard the contaminated needle safely and choose a new sterile needle to continue the procedure. This step helps prevent potential transmission of infections and ensures the safety of both the individual and the patient. Disinfecting the needle with an alcohol swab is not adequate to address the risk of infection transmission. While completing an incident report and notifying the supervisor are important, the immediate action should be to replace the contaminated needle with a new sterile one to prevent any potential harm.

Correct Answer: D

Rationale: Direct observation of the client performing the skill is the most effective method to assess the client's ability to independently change the dressing. This allows the healthcare provider to evaluate the client's technique, understanding, and readiness to perform the task at home. Choices A, B, and C are not as reliable as directly observing the client performing the dressing change. Determining the client's feelings may not accurately reflect their ability, asking the client to write about the procedure may not demonstrate their practical skills, and having a family member evaluate might not provide an accurate assessment of the client's ability.
