ATI PN Comprehensive Predictor 2020

Correct Answer: B

Rationale: The correct safety measure that the nurse should emphasize is to keep oxygen tanks upright and away from heat sources. This is crucial to prevent the risk of fire or explosion. Choice A is incorrect as smoking near oxygen can lead to a fire hazard. Choice C is also incorrect as storing oxygen tanks in enclosed spaces can be dangerous. Choice D, although related to safety, does not address the immediate risk of keeping oxygen tanks away from heat sources.

Correct Answer: B

Rationale: The correct answer is B: Place the client in a 30-degree lateral position. Positioning the client laterally reduces pressure on bony prominences, improving circulation and helping prevent pressure injuries. Placing the client in a prone position (choice A) increases pressure on the bony prominences, raising the risk of pressure injuries. Similarly, placing the client in a high Fowler's position (choice D) can also increase pressure on certain areas. While encouraging the client to reposition every 4 hours (choice C) is important, the specific lateral positioning is more beneficial in preventing pressure injuries.

Correct Answer: A

Rationale: Hand hygiene is considered the most effective method to prevent the spread of infection in a healthcare setting. Proper hand hygiene, including washing hands with soap and water or using hand sanitizer, is crucial in reducing the transmission of pathogens from one person to another. While wearing personal protective equipment, sterilizing equipment, and isolating infected patients are also important infection control measures, they are not as universally effective as hand hygiene in preventing the spread of infections. Personal protective equipment can prevent contact with infectious materials, sterilizing equipment reduces the risk of contamination, and isolating infected patients helps prevent the spread of specific infections, but they are more targeted approaches compared to the broad and essential practice of hand hygiene.

Correct Answer: A

Rationale: The correct answer is A: Obesity, sedentary lifestyle, and poor diet are established risk factors for developing Type 2 diabetes. Obesity puts extra pressure on the body's ability to properly control blood sugar levels. A sedentary lifestyle contributes to weight gain and insulin resistance. Poor diet, especially one high in processed foods and sugary beverages, can also increase the risk of developing Type 2 diabetes. Choices B, C, and D are incorrect because age, gender, family history, smoking, alcohol consumption, and hypertension can impact overall health but are not the primary risk factors for Type 2 diabetes.

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.
