Fundamentals HESI

Correct Answer: A

Rationale: The correct statement is: 'The temperature around the IV site is cooler.' Cooler temperature around the site is indicative of infiltration, where IV fluid leaks into the surrounding tissue, causing tissue swelling. The other options are incorrect: B) An increase in infusion rate is not a sign of infiltration; instead, it could indicate an issue with the infusion pump or the IV catheter. C) Redness around the IV site is more indicative of infection rather than infiltration. D) A damp IV dressing is more suggestive of a leak in the IV system, not infiltration.

Correct Answer: A

Rationale: Athlete's foot, also known as tinea pedis, is a contagious fungal infection that can easily spread to other body parts, particularly the hands. It often recurs if not properly treated, making choice A the correct answer. Choices B and C are incorrect because while it is beneficial to air-dry feet after bathing to prevent moisture buildup, athlete's foot is commonly treated with antifungal medications, not salicylic acid. Choice D is incorrect because athlete's foot is caused by a fungal infection, not lice.

Correct Answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

Correct Answer: C

Rationale: The statement 'I can't find my missing shoes. Have you seen them?' displays disorganized thinking or speech, which is characteristic of a thought disorder. The mention of 'missing shoes' in a context that does not make logical sense suggests a disturbance in thought processes. Choices A, B, and D do not demonstrate disorganized thinking typical of thought disorders. Option A reflects emotional expression, option B indicates mild confusion, and option D shows a redirection of focus to someone else's problem.

Correct Answer: A

Rationale: The correct answer is A because clients taking digoxin should avoid foods high in potassium. High potassium levels can potentiate the effects of digoxin, leading to toxicity. Choices B, C, and D are correct statements regarding digoxin administration. Checking the pulse before taking the medication helps monitor for signs of digoxin toxicity. Avoiding taking antacids simultaneously prevents interactions that may reduce digoxin absorption. Taking the medication at the same time every day helps maintain a consistent blood level, ensuring optimal therapeutic effects.
