ATI PN Comprehensive Predictor 2023

Correct Answer: A

Rationale: The correct answer is A: Excessive thirst and fruity breath odor. Diabetic ketoacidosis presents with these early signs due to ketone buildup in the body. Choice B, weight loss and increased urination, are more characteristic of uncontrolled diabetes but not specific to diabetic ketoacidosis. Choice C, nausea and vomiting, can occur in diabetic ketoacidosis but are not as early or specific as excessive thirst and fruity breath odor. Choice D, hypoglycemia and fatigue, are not typical signs of diabetic ketoacidosis; rather, diabetic ketoacidosis usually presents with hyperglycemia.

Correct Answer: D

Rationale: Correct Answer: Green leafy vegetables - Green leafy vegetables are high in vitamin K, which can interfere with the effectiveness of warfarin. Tomatoes, apples, and broccoli are not contraindicated with warfarin therapy. While they are healthy choices, they do not have a significant impact on warfarin's effectiveness.

Correct Answer: B

Rationale: The correct answer is B: Administer insulin before meals as prescribed. This is the most important teaching point because insulin administration before meals helps manage blood sugar effectively in diabetic patients. Choice A is incorrect because monitoring blood sugar levels weekly may not provide timely information for managing diabetes. Choice C is incorrect as medications for diabetes should be taken as prescribed, not only when feeling unwell. Choice D is incorrect as blood sugar levels should be monitored at various times throughout the day, not just in the morning, to get a complete picture of the patient's condition.

Correct Answer: B

Rationale: The correct answer is B: 'Keep oxygen tanks upright at all times.' Oxygen tanks should be stored in an upright position to prevent leaks and accidents. Choice A is incorrect as smoking should never be allowed near oxygen due to the risk of fire. Choice C is incorrect as oxygen equipment should be stored in a well-ventilated area, not in a closet. Choice D is incorrect as oxygen tanks must be kept a minimum of 5 to 10 feet away from heat sources to prevent combustion. Therefore, the best practice is to keep oxygen tanks upright to ensure safety.

Correct Answer: B

Rationale: Acetylcysteine is the antidote for acetaminophen overdose. It works by replenishing glutathione, a key component in detoxifying acetaminophen metabolites, thus preventing liver damage. Naloxone is used to reverse opioid overdose, not acetaminophen. Flumazenil is a benzodiazepine antidote. Activated charcoal is used to limit absorption in cases of poisoning, but it is not the antidote for acetaminophen overdose.
