HESI Fundamentals Practice Exam

Correct Answer: B

Rationale: During a fire evacuation, it is crucial for ambulatory clients to be reminded to walk carefully down the stairs. This helps ensure the safety of the client by preventing falls or injuries during the evacuation process. Directing the client to proceed cautiously down the stairs until reaching a lower floor provides necessary guidance to promote a safe evacuation process. Choice A is incorrect because assigning unlicensed assistive personnel to transport the client via a wheelchair may delay the evacuation process and increase the risk of injury. Choice C is incorrect as it distracts the ambulatory client from evacuating safely by involving them in assisting another client. Choice D is incorrect as opening fire doors may not be the most appropriate action at that moment; prioritizing safe evacuation procedures for ambulatory clients is essential.

Correct Answer: A

Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.

Correct Answer: C

Rationale: Limiting saturated fat from animal food sources to no more than 4 ounces per week is an important diet modification for lowering cholesterol. To be effective in reducing cholesterol, the client should exercise 30 minutes per day, or at least 4 to 6 times per week. Red meat and all proteins do not need to be eliminated to lower cholesterol, but should be restricted to lean cuts of red meat and smaller portions. The low density lipoproteins need to decrease rather than increase.

Correct Answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.
