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 most appropriate intervention for a client with dementia at risk of falls is to use a bed exit alarm to notify staff of attempts to leave the bed. This intervention allows for timely assistance and prevents falls. Raising all four side rails (Choice B) can lead to entrapment or agitate the client. Encouraging frequent ambulation with assistance (Choice C) may not be suitable for a client at high risk of falls. Using restraints (Choice D) should be avoided as they can increase agitation, risk of injury, and have ethical implications.

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.

Correct Answer: B

Rationale: The axillary method is the most appropriate for newborns because it is non-invasive and safe. Rectal temperature measurement can be uncomfortable and poses a risk of injury, especially in newborns. Oral temperature measurement is not recommended for newborns due to their inability to cooperate and potential inaccuracies. Tympanic temperature measurement may not be as accurate in newborns compared to older children or adults.

Correct Answer: B

Rationale: The correct answer is to prioritize investigating the client's medication history. This is important because certain medications can contribute to agitation in clients with dementia. Understanding the medication history can help identify potential causes of agitation and guide appropriate interventions. Checking for fluid and electrolyte imbalances is important in healthcare but may not directly relate to the client's agitation. While environmental factors can influence behavior, investigating the medication history is more pertinent in this case. Cognitive functioning assessment is crucial in dementia care but may not be the priority when addressing acute agitation.
