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: A

Rationale: Observing a colleague accessing a patient's EHR without a legitimate reason is a violation of HIPAA, which protects patient confidentiality. The appropriate action in this scenario is to communicate the colleague's actions to the unit charge nurse immediately. The charge nurse can then address the issue internally and ensure that patient privacy is maintained. Reporting the incident through the appropriate channels within the healthcare facility is the most effective and professional way to handle such breaches of patient confidentiality. Choices B, C, and D are incorrect because they do not involve addressing the issue internally within the healthcare facility. Reporting such incidents internally is essential to ensure that patient privacy is protected, and the matter is handled appropriately by healthcare authorities.

Correct Answer: B

Rationale: When caring for an immobile client, the nursing diagnosis with the highest priority is impaired gas exchange. This is because impaired gas exchange implies difficulty with breathing, which is essential for sustaining life. Adequate oxygenation is crucial for all bodily functions, and any impairment in gas exchange can lead to serious complications, making it the priority nursing diagnosis to address in an immobile client. Choices A, C, and D are important considerations as well when caring for an immobile client, but they are secondary to impaired gas exchange. Risk for fluid volume deficit may occur due to immobility, but ensuring proper gas exchange takes precedence as it directly impacts the client's immediate survival. Risk for impaired skin integrity is a concern in immobile clients but does not pose an immediate threat to life like impaired gas exchange. Altered tissue perfusion is also critical but is usually a consequence of impaired gas exchange, reinforcing the priority of addressing gas exchange first.

Correct Answer: A

Rationale: Increased oxygen saturation (A) is the most direct indicator of the effectiveness of albuterol (Proventil) in improving breathing. Oxygen saturation reflects the amount of oxygen in the blood, showing that the albuterol is helping with air exchange in the lungs. While decreased respiratory rate (B), absence of audible wheezing (C), and improved exercise tolerance (D) are positive outcomes, they are secondary to oxygen saturation. Oxygen saturation directly reflects the improvement in the client's respiratory status and the effectiveness of the medication.

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.
