ATI PN Comprehensive Predictor 2020

Correct Answer: B

Rationale: The correct answer is B: 'Wear shoes that fit properly.' In peripheral arterial disease (PAD), it is crucial to wear shoes that fit well to prevent foot injuries. Choice A is incorrect because applying lotion between the toes can increase the risk of infection. Choice C is incorrect since walking barefoot at home can lead to injuries, especially in individuals with PAD. Choice D is incorrect as applying ice to the feet daily can further reduce blood flow to the extremities, worsening the condition in PAD.

Correct Answer: B

Rationale: The correct answer is B - 'Identify the underlying causative condition.' When a client is experiencing delirium, it is crucial to determine the root cause of this acute change in mental status. This can involve a thorough assessment to identify any medical conditions, medications, infections, or environmental factors that may be contributing to the delirium. By pinpointing the underlying cause, appropriate interventions can be implemented to address the specific issue. Choices A, C, and D are incorrect because controlling behavioral symptoms with low-dose psychotropics, increasing environmental stimulation, and administering antipsychotic medication do not target the primary need of identifying and addressing the causative condition of delirium.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Hypokalemia is an adverse effect of digoxin. Digoxin can cause hypokalemia, which increases the risk of toxicity. Monitoring potassium levels is crucial when a client is taking digoxin. Choices B, C, and D are incorrect as hypernatremia, hypertension, and tachycardia are not directly associated with digoxin use.

Correct Answer: C

Rationale: The correct answer is to suction the client when they show signs of irritability. Signs of irritability, such as restlessness or agitation, can indicate the need for suctioning in a client with a tracheostomy. This early indicator suggests that there may be an accumulation of secretions affecting the client's airway. Suctioning should be performed promptly to maintain a clear airway and prevent complications. Choices A, B, and D are incorrect because suctioning should be based on clinical signs and symptoms indicating the need for intervention, rather than a fixed schedule or specific vital sign parameters.

Correct Answer: A

Rationale: Hypokalemia is managed by administering potassium supplements to correct the low potassium levels in the body. Monitoring the ECG is essential because low potassium levels can lead to cardiac arrhythmias. Choice B is incorrect as restricting fluid intake and providing a high-sodium diet are not appropriate for managing hypokalemia. Choice C is incorrect because hypokalemia involves low potassium levels, not sodium levels, and insulin therapy does not directly address this issue. Choice D is incorrect as calcium supplements are not indicated for hypokalemia, and monitoring for hyperkalemia is not relevant in this case.
