ATI PN Comprehensive Predictor 2020

Correct Answer: D

Rationale: The correct intervention for a client with dementia at risk of falling is to use a bed exit alarm to notify staff of attempts to leave the bed. This intervention helps in preventing falls by alerting the staff when the client tries to get out of bed. Keeping the bed in the lowest position (Choice A) may not prevent falls and could make it challenging for staff to provide care. Raising all four side rails (Choice B) can be a restraint and is not recommended as it may lead to entrapment or other risks. Assisting with ambulation every 2 hours (Choice C) may not be feasible or effective in preventing falls, as the client may attempt to get out of bed at any time.

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: A

Rationale: The correct answer is A: Prostate-specific antigen (PSA). PSA is a marker specifically used for prostate cancer screening. Elevated levels of PSA can indicate prostate cancer or other prostate-related issues, prompting the need for further diagnostic investigations. Choices B, C, and D are not typically associated with prostate cancer screening. Human chorionic gonadotropin (hCG) is related to pregnancy, alpha-fetoprotein (AFP) is associated with liver and germ cell tumors, and carcinoembryonic antigen (CEA) is linked to colorectal cancer.

Correct Answer: B

Rationale: Performing a wound culture before applying antibiotics is crucial for determining the specific type of infection present and selecting the most effective antibiotic treatment. Changing the dressing daily (Choice A) is a routine wound care practice but may not address the root cause of the infection. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and delay wound healing. Applying a wet-to-dry dressing (Choice D) is an outdated practice that can cause trauma to the wound bed and hinder the healing process.

Correct Answer: A

Rationale: After removing an IV catheter due to phlebitis, the next step is to apply a warm compress over the IV site. This helps reduce inflammation and discomfort for the client. Recording the findings in the client's chart is important for documentation purposes but not the immediate next step. Notifying the client's primary care provider may be necessary depending on the severity of the phlebitis, but it is not the initial action. Inserting a new IV catheter is not appropriate until the phlebitis has resolved.
