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: Monitoring the client's respiratory rate and effort is essential to evaluate the effectiveness of oxygen therapy and prevent complications such as respiratory depression. This intervention helps the nurse promptly detect any deterioration in the client's respiratory status and take necessary actions to ensure the client's safety. Encouraging continuous oxygen use (Choice A) may lead to oxygen toxicity. Setting the oxygen flow rate at a specific level (Choice C) without individual assessment can be inappropriate and potentially harmful. Teaching the client to avoid wearing wool blankets (Choice D) is unrelated to the safe use of oxygen therapy.

Correct Answer: A

Rationale: In the scenario where a nurse administers a medication outside the prescribed parameters, the immediate action should be to assess the client for any potential side effects of the medication. This is crucial to ensure the client's safety and well-being. By promptly assessing for side effects, the nurse can address any adverse reactions promptly and provide necessary interventions. Once the client's safety is ensured, documenting the client's responses, completing a medication error report, and assessing pain relief can follow as part of the broader response to the medication error. Choice B is not the first priority because the immediate concern is the potential harm from the incorrect dose. Choice C is also important but comes after ensuring the client's safety. Choice D focuses on the outcome rather than the immediate need to address any side effects of the medication.

Correct Answer: B

Rationale: Positioning the client in low Fowler's position after a craniotomy is essential to promote drainage from the operation site. This position helps prevent fluid accumulation, facilitates the removal of excess fluid or blood, and aids in the healing process. Choice A is incorrect because comfort, while important, is not the primary reason for this specific positioning. Choice C is incorrect as thoracic expansion is not the main concern following a craniotomy. Choice D is incorrect as circulatory overload is not typically addressed by positioning in low Fowler's position post-craniotomy.

Correct Answer: B

Rationale: Administering oxygen via nasal cannula (B) is the priority intervention for a client with COPD exacerbation to improve oxygenation. In COPD exacerbation, there is impaired gas exchange leading to hypoxemia, making oxygen therapy the initial priority. Administering bronchodilators (A) helps with bronchodilation but should come after ensuring adequate oxygenation. Encouraging coughing and deep breathing (C) and positioning the client in high Fowler's position (D) are also beneficial interventions, but the first step is to address the oxygenation needs of the client.
