ATI Comprehensive Predictor PN

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 nurse should question the dosage of haloperidol as it is typically administered in milligrams (mg) and not milliliters (mL). The dosage should be expressed in a standardized unit for accuracy and to prevent medication errors. Frequency, timing of doses, and route are also important components of a prescription, but in this case, the nurse should focus on the unusual dosage form.

Correct Answer: D

Rationale: The correct answer is D. New onset of tachypnea indicates a potential respiratory complication that requires immediate attention. Assessing the client with a hip fracture and tachypnea first is crucial to address the respiratory issue and prevent further deterioration. Choices A, B, and C do not present immediate life-threatening complications that require urgent assessment compared to a new onset of tachypnea.

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: C

Rationale: The most important nursing action when administering IV potassium is to administer it slowly and dilute it in IV fluids. This approach helps prevent irritation and hyperkalemia. Monitoring for decreased urine output (Choice A) is important but not as critical as ensuring the safe administration of IV potassium. Administering potassium via IV push (Choice B) is unsafe and can lead to adverse effects. Ensuring the client drinks water before administration (Choice D) is not directly related to the safe administration of IV potassium.
