Correct Answer: B

Rationale: Monitoring Serum Vancomycin levels is essential to determine the drug's therapeutic range, ensuring optimal effectiveness while avoiding toxicity. Peak levels indicate the drug's highest concentration, while trough levels represent the lowest concentration before the next dose. Assessing renal function is typically done using creatinine, BUN, or creatinine clearance tests, not Serum Vancomycin levels. Evaluating antibiotic resistance involves sensitivity testing, not monitoring Vancomycin levels. Therefore, the correct answer is to determine the therapeutic range.

Correct Answer: A

Rationale: The best approach to dealing with resistance to change is through open communication and understanding. Meeting with the CNA and encouraging him to express his feelings regarding the change allows for a constructive dialogue where issues can be addressed, and alternative solutions can be explored. Ignoring the resistance does not help in resolving the conflict and may lead to further issues. Telling the CNA that a licensed practical nurse (LPN) will perform all computer documentation while he documents intake and output and vital signs does not address the underlying concerns of the CNA and may create more resistance. Threatening the CNA with noncompliance consequences may escalate the resistance and create a negative work environment.

Correct Answer: A

Rationale: A case manager is responsible for coordinating a client's care and monitoring for unexpected outcomes. The situation that indicates an unexpected outcome and the need for immediate follow-up is when a client exhibits signs of increased intracranial pressure after a craniotomy. This indicates a deteriorating condition that requires urgent intervention. Choices B, C, and D describe expected outcomes or normal findings related to specific conditions, which do not demand immediate follow-up.

Correct Answer: C

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

Correct Answer: D

Rationale: The correct answer is 'Hispanic.' Hispanic individuals in the United States are at a higher risk for pesticide-related injuries due to their representation among migrant workers in agricultural settings. This exposure to pesticides in their work environments increases their risk compared to other ethnic groups. Choice A, 'Native American,' although indigenous populations may face environmental health disparities, the higher risk in this context is among Hispanic individuals. Choice B, 'Asian-Pacific,' and Choice C, 'Norwegian,' do not have the same level of exposure to pesticides as Hispanic migrant workers, making them less susceptible to pesticide-related injuries.
