Correct Answer: B

Rationale: Checking the placement of the NG tube before each feeding is crucial as it ensures the tube is correctly positioned, reducing the risk of complications such as aspiration or improper delivery of feedings. Flushing the NG tube with water before and after each feeding can disrupt the feeding schedule and is not a standard procedure. Administering medications through the NG tube every 4 hours may not be necessary for all patients and should be based on specific medication requirements. Increasing the feeding rate without proper assessment and monitoring can lead to feeding intolerance or complications, making it an inappropriate intervention.

Correct Answer: A

Rationale: The correct answer is A: White blood cell count (WBC). Monitoring the white blood cell count is crucial when caring for a patient with an infection as it helps assess the body's response to the infection. An elevated white blood cell count often indicates an active infection or inflammation, while a decreasing count may signal improvement or potential complications. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are nonspecific markers of inflammation and not as specific to monitoring infection progression as the white blood cell count. Hemoglobin and hematocrit levels are important for assessing oxygen-carrying capacity and blood volume, but they are not the primary indicators for monitoring infection.

Correct Answer: C

Rationale: The most important action for the nurse to take after finding a patient on the floor who reports falling out of bed is to notify the health care provider. This is crucial to ensure that the incident is reported, documented, and that the patient receives necessary follow-up care. Reassessing the patient is important, but notifying the healthcare provider takes precedence to address any potential injuries or issues that may have resulted from the fall. Completing an incident report is necessary, but immediate notification to the healthcare provider is more critical in this situation. Doing nothing is not an appropriate response, as the patient's safety and well-being must be the top priority.

Correct Answer: A

Rationale: Auscultating the entire lung region is the most appropriate action when assessing a patient for respiratory complications related to immobility. This approach helps the nurse identify any abnormalities in lung sounds, such as diminished breath sounds or the presence of secretions. Assessing the patient at regular intervals (choice B) is important but does not specifically address the respiratory assessment needed in this situation. Focusing auscultation on the upper lung fields (choice C) may miss potential issues in other areas. Inspecting chest wall movements primarily during the expiratory cycle (choice D) is not the most effective way to assess lung sounds and identify respiratory complications.

Correct Answer: B

Rationale: If a nurse manager assigns a nursing assistant a task that is outside of their role, the nursing assistant should report the task to the charge nurse. This is important because the charge nurse can provide guidance on whether the task is appropriate for the nursing assistant to perform. Choice A is incorrect because blindly following a directive that is outside of the nursing assistant's scope could lead to negative consequences. Choice C might not be the best course of action initially, as it's important to seek clarification first. Choice D is also not the best option because performing a task outside of one's role without proper authorization can pose risks to both the patient and the nursing assistant.
