Correct Answer: C

Rationale: The correct answer is C. For droplet precautions, such as in the case of pertussis, a standard face mask is sufficient for protection. Particulate filter masks are required for airborne precautions, not for droplet precautions. Therefore, the UAP can proceed with taking the vital signs using a standard mask without the need for a particulate filter mask. It is important for healthcare workers to understand the appropriate use of personal protective equipment based on the type of precautions in place to provide safe and effective care to clients.

Correct Answer: D

Rationale: Vitamin B12 is an essential nutrient that is predominantly found in animal products. Since individuals following a vegan diet do not consume animal products, they are at a higher risk of vitamin B12 deficiency. Therefore, it is crucial for vegans to include a vitamin B12 supplement in their dietary plan to prevent deficiency-related health issues.

Correct Answer: C

Rationale: In this scenario, the nurse acted appropriately by withholding the medication, consulting with the healthcare provider, and administering the newly prescribed dose, albeit with a delay. The correct course of action for the nurse is to document all these events in the nurse's notes. Documenting the sequence of actions taken is crucial for maintaining an accurate record of the client's care, ensuring transparency, and providing essential information for future reference and continuity of care.

Correct Answer: C

Rationale: The ANA's Scope and Standards of Nursing Practice are essential guidelines for nursing practice in various specialties, including mental health. The document outlines the expectations and responsibilities of nurses in providing high-quality care within their specific practice areas. In the context of opening a mental health services department, using the Scope and Standards specific to psychiatric-mental health nursing would ensure that the unit's nursing guidelines align with best practices and professional standards in mental health care.

Correct Answer: C

Rationale: A report of shortness of breath (C) indicates that the client is not tolerating the oxygen therapy well and may need an adjustment. Shortness of breath is a critical symptom in a client with COPD, as it signifies potential respiratory distress. A respiratory rate of 14 (A), oxygen saturation of 92% (B), and respiratory rate of 24 (D) are not as immediately concerning as they may still fall within acceptable ranges for a client with COPD.
