Correct Answer: A

Rationale: The correct answer is A: Inability to communicate. Critically ill patients often experience pain and anxiety due to their inability to effectively communicate their needs and discomfort. This can lead to unaddressed pain and increased anxiety levels. Choices B, C, and D are incorrect because while invasive procedures, monitoring devices, and preexisting conditions can contribute to pain and anxiety in critically ill patients, they are not factors that directly predispose patients to these issues. It is the lack of communication that significantly hinders the ability to address and manage pain and anxiety effectively in these patients.

Correct Answer: B

Rationale: The correct answer is B: Assign the client to a negative air-flow room. This is crucial to prevent the spread of TB to other patients and healthcare workers. Negative air-flow rooms help contain airborne pathogens. Option A is not sufficient as it only protects the client, not others. Option C is important for infection control but not the priority in this situation. Option D is not as effective as placing the client in a negative air-flow room. Overall, option B is the best choice to ensure the safety of everyone in the unit.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Ensuring the IABP console is turned off is crucial to prevent further complications and stop potential harm to the patient. 2. By turning off the IABP console, the nurse can halt the pumping action, allowing assessment of the situation without interference. 3. This action takes priority over other steps as it addresses the immediate issue of blood backing up into the IABP catheter. 4. Once the console is turned off, the nurse can proceed with assessing the patient's vital signs, notifying the healthcare provider, and obtaining supplies if needed. Summary of Incorrect Choices: - Option B: Assessing vital signs and orientation is important, but addressing the malfunction of the IABP takes precedence to prevent harm. - Option C: Notifying the healthcare provider is necessary, but first, the immediate issue of blood backing up into the catheter must be addressed. - Option D: Obtaining supplies for a new catheter is premature without first addressing

Correct Answer: A

Rationale: The correct answer is A: Elevated creatinine. Ibuprofen can cause kidney damage, leading to elevated creatinine levels. This is because ibuprofen is metabolized in the kidneys, and prolonged use can impair kidney function. Elevated platelet count (B), elevated white blood count (C), and low liver enzymes (D) are not typically associated with ibuprofen use. Platelet count and white blood count are more related to inflammation or infection, while low liver enzymes are not a common side effect of ibuprofen.

Correct Answer: A

Rationale: The correct answer is A because allowing family members to remain at the bedside can provide emotional support and comfort to the patient, helping them feel safe in the critical care setting. Family presence can also facilitate communication and understanding between the healthcare team and the patient. Choice B is incorrect because consulting with the charge nurse before making patient care decisions may not directly contribute to the patient feeling safe. Choice C is incorrect because providing informal conversation about work-related topics may not address the patient's need for safety and security in the critical care setting. Choice D is incorrect because explaining how to communicate for assistance is important for patient care but may not directly contribute to the patient's sense of safety in the critical care setting.
