Correct Answer: B

Rationale: The correct answer is to assist the patient to sit down slowly. This intervention is appropriate for a patient experiencing dizziness when standing up, as it helps prevent falls due to orthostatic hypotension. Encouraging deep breaths (Choice A) may not address the underlying cause of dizziness, which is related to postural changes. Instructing the patient to use a walker for support (Choice C) or teaching the patient how to change positions safely (Choice D) are not the most immediate and direct interventions to address the immediate risk of falling when feeling dizzy upon standing.

Correct Answer: C

Rationale: The primary purpose of turning and repositioning an immobile patient every 2 hours is to prevent skin breakdown and pressure ulcers. Prolonged immobility can lead to pressure ulcers, making this a crucial nursing intervention. Choice A is incorrect because while turning can help improve circulation and relieve pressure, the primary purpose is to prevent skin breakdown. Choice B is incorrect as preventing contractures and muscle atrophy is important but not the primary purpose of turning. Choice D is incorrect as improving respiratory function and preventing pneumonia are not directly related to turning and repositioning for skin integrity.

Correct Answer: B

Rationale: The correct first step for the nurse when encountering a medication order that appears excessively high for the patient's condition is to hold the medication and consult the provider. Administering the medication immediately (Choice A) without clarification could pose a risk to the patient's safety. Reducing the dose without consulting the provider (Choice C) is not recommended as it may lead to suboptimal treatment. Administering the medication after double-checking with another nurse (Choice D) is not sufficient; consulting the provider directly is crucial to ensure the accuracy and safety of the medication order.

Correct Answer: B

Rationale: Using bed alarms to prevent falls is the most important intervention to implement for a client with a history of falls. Bed alarms can provide timely alerts to the healthcare team, allowing for quick assistance to prevent falls. Increasing the frequency of bed checks may not necessarily prevent falls as effectively as direct intervention with bed alarms. Keeping the room well lit is important for general safety but may not address the immediate risk of falls. Encouraging the client to use a walker for mobility is beneficial but may not be as crucial as implementing bed alarms to prevent falls in this scenario.

Correct Answer: A

Rationale: The most critical lifestyle change for a patient with hypertension is to reduce salt intake. Excessive salt consumption can lead to increased blood pressure levels. While limiting alcohol consumption (Choice B) and regular exercise (Choice C) are also beneficial for managing hypertension, reducing salt intake has a more direct impact on blood pressure control. Avoiding high-cholesterol foods (Choice D) is important for heart health but may not have as significant an impact on blood pressure as reducing salt intake.
