ATI Comprehensive Predictor PN

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.

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 most appropriate intervention for a client with left-leg weakness learning to use a cane is to maintain two points of support on the floor at all times. This ensures stability and helps distribute weight evenly between the legs, reducing the risk of falls. Using the cane on the weak side of the body (Choice B) may not provide adequate support. Advancing the cane and the strong leg simultaneously (Choice C) can lead to imbalance and increases the risk of falls. Advancing the cane too far with each step (Choice D) can also compromise balance and stability.

Correct Answer: B

Rationale: The correct answer is B: Fever. Fever in a postoperative client can indicate an infection, which is a serious complication and should be reported immediately to the provider for further evaluation and management. Clear lung sounds (Choice A) are a positive finding indicating normal respiratory function. Pain in the operative leg (Choice C) is expected postoperatively and should be managed with appropriate pain relief measures. Capillary refill of 2 seconds (Choice D) is within the normal range (less than 3 seconds) and is not a concerning finding postoperatively.

Correct Answer: A

Rationale: Low birth weight increases a child's vulnerability to physical maltreatment due to additional care needs. Advanced maternal age (choice B) is not directly linked to an increased risk of physical maltreatment. Single parenthood (choice C) is not a characteristic that inherently increases the risk of physical maltreatment. Premature birth (choice D) is not listed as a characteristic that directly increases a child's risk of physical maltreatment.
