ATI Comprehensive Predictor PN

Correct Answer: B

Rationale: The correct first step in preparing a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to ensure compatibility and prevent adverse reactions. Administering the blood via IV push (Choice A) is incorrect as it skips the essential step of verifying the blood type. Warming the blood to body temperature (Choice C) is important but comes after verifying the blood type. Administering diuretics (Choice D) is not part of the preparation process for a blood transfusion.

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: B

Rationale: When caring for clients with dementia, addressing restlessness and agitation is a priority as it can lead to distress, safety risks, and potential harm to the client or others. Restlessness and agitation are common behavioral symptoms of dementia and can indicate unmet needs, discomfort, or confusion. Managing these symptoms promptly can help improve the client's quality of life and prevent complications such as falls, injuries, or escalation of challenging behaviors. While other issues like mild confusion, incontinence, and wandering are also important to address, managing restlessness and agitation takes precedence due to its immediate impact on the client's well-being and safety.

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: A

Rationale: Corrected Question: When assessing a patient with hyperkalemia, monitoring the ECG and administering insulin are crucial steps. Hyperkalemia can affect the heart's function, leading to life-threatening arrhythmias. Monitoring the ECG helps in identifying any cardiac abnormalities associated with high potassium levels. Administering insulin, along with glucose, helps shift potassium from the bloodstream into the cells, temporarily lowering the potassium levels. Choice B is incorrect because monitoring blood glucose levels and providing fluids are not the primary interventions for hyperkalemia. Choice C is incorrect as monitoring for muscle weakness and administering calcium gluconate are not the first-line treatments for hyperkalemia. Calcium gluconate may be used in specific situations to stabilize cardiac cell membranes in severe cases of hyperkalemia. Choice D is incorrect because monitoring electrolyte levels and providing potassium supplements would worsen hyperkalemia, as the patient already has elevated potassium levels and does not require additional potassium supplementation.
