ATI PN Comprehensive Predictor 2020

Correct Answer: B

Rationale: Performing a wound culture before administering antibiotics is crucial when managing a client with a wound infection. This step helps identify the specific pathogens causing the infection, allowing for the prescription of the most effective antibiotics. Changing the wound dressing every 24 hours (Choice A) is important for wound care but not the priority when an infection is present. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and may delay wound healing. Applying a wet-to-dry dressing (Choice D) is not recommended for infected wounds as it can cause trauma to the wound bed during dressing changes.

Correct Answer: B

Rationale: The correct answer is B because taking warfarin later on the same day if a dose is missed helps maintain therapeutic levels. Choice A is incorrect because warfarin should be taken with food to enhance absorption. Choice C is incorrect as skipping a dose can lead to fluctuations in warfarin levels. Choice D is incorrect as taking an additional dose can increase the risk of bleeding.

Correct Answer: B

Rationale: The correct answer is to investigate the client's recent medication changes. In a client with dementia who frequently becomes agitated, medication changes can often be a significant factor contributing to their behavior. Checking recent medication changes can help identify if any specific medication is causing or exacerbating the agitation. Choice A about fluid and electrolyte balance is less likely to be the priority unless there are specific indications in the medical record. Choice C, investigating recent changes in cognitive functioning, may be important but addressing the agitation first is a more immediate concern. Choice D, investigating the client's psychosocial environment, is also important but may not directly address the immediate cause of the agitation as medication changes could.

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: 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.
