ATI Comprehensive Predictor PN

Correct Answer: C

Rationale: The correct answer is C: Apply a sequential compression device. Applying a sequential compression device promotes venous return by assisting with blood circulation in the lower extremities, reducing the risk of blood clots. Encouraging deep breathing exercises can help with lung expansion but does not directly promote venous return. Maintaining the client in a supine position may not be ideal for promoting venous return if the client is unable to move. Massaging the client's legs may be contraindicated postoperatively due to the risk of dislodging a clot or causing trauma to the surgical site.

Correct Answer: A

Rationale: The correct answer is A: Staphylococcus aureus infections, including MRSA. Severe infections like MRSA are required to be reported to the health department as they pose a significant public health risk. Choices B, C, and D are incorrect because severe flu-like symptoms, common colds, and non-severe respiratory infections, and only contagious diseases like meningitis do not fall under the category of infectious diseases that must be reported to the health department.

Correct Answer: A

Rationale: The nurse plays a crucial role in preoperative patient care by providing education and ensuring NPO (nothing by mouth) status. This helps prepare the patient for surgery by ensuring they understand the procedure, what to expect, and also by following necessary preoperative fasting guidelines. While obtaining the patient's health history (choice C) is important for overall patient assessment, it is typically done during the preoperative assessment but does not specifically pertain to the nurse's role. Ensuring informed consent (choice B) is primarily the responsibility of the healthcare provider performing the procedure. Confirming the patient's surgical site (choice D) is usually the responsibility of the surgical team and is done immediately before the surgery to prevent errors.

Correct Answer: A

Rationale: Assessing mobility should be the nurse's priority as it ensures the client's safety and helps in developing an appropriate care plan. By evaluating the client's ability to move after the knee arthroplasty, the nurse can identify any immediate issues or complications that need to be addressed promptly. Monitoring vital signs, providing pain relief, and reinforcing discharge teaching are important aspects of care but assessing mobility takes precedence in ensuring the client's immediate well-being and identifying any potential risks.

Correct Answer: B

Rationale: The correct answer is B: Ensure the blood type is compatible with the client. This is the most crucial step in preparing for a blood transfusion to prevent severe transfusion reactions. Checking the client for a fever (Choice A) is important but not the most critical step. Administering blood via IV push (Choice C) is incorrect as blood transfusions are usually administered as a slow drip. Warming the blood to body temperature (Choice D) is not a standard practice and can lead to hemolysis, making it an incorrect choice.
