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 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: C

Rationale: Evaluating hemoglobin A1c levels is the most appropriate intervention to assess glycemic control in a client with type 2 diabetes mellitus.

Correct Answer: B

Rationale: When faced with caring for a close friend in a professional setting, it is essential to maintain professional boundaries. The best course of action is to disclose the relationship to the charge nurse and request reassignment to prevent any potential conflicts of interest or compromised care.

Correct Answer: B

Rationale: Avoiding foods high in sodium (choice B) is essential for clients with heart failure to prevent fluid retention and decrease the strain on the heart. High sodium intake can lead to fluid buildup, exacerbating heart failure symptoms. Increasing potassium intake (choice A) can be harmful in heart failure if not monitored closely. Limiting fluid intake (choice C) may be necessary in some cases, but the specific amount should be individualized based on the client's condition. Increasing vitamin K intake (choice D) is not a primary concern in heart failure management.
