HESI Fundamentals Practice Exam

Correct Answer: B

Rationale: After ensuring the correct placement of the NGT, the nurse should flush the tube with water to prevent any obstructions and ensure proper medication delivery. Flushing the tube is essential before, after, and in between each medication administration. Clamping the tube for 20 minutes should be done after all medications are administered to prevent clogging. Administering medications as prescribed and preparing medications by crushing tablets and dissolving them in sterile water should only be done after the tube has been appropriately flushed to maintain its patency and effectiveness.

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: 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: Administering regular insulin IV (A) is the initial intervention for a client with diabetic ketoacidosis (DKA) to rapidly reduce blood glucose levels. This is vital in reversing the ketosis and acidosis seen in DKA. Administering IV fluids (B) helps to correct dehydration and electrolyte imbalances. Administering sodium bicarbonate (C) and furosemide (D) may be necessary depending on the client's condition, but insulin administration takes precedence in the management of DKA.

Correct Answer: D

Rationale: Before assisting the client out of bed, the nurse should first assess the client's blood pressure and pulse. This assessment is crucial to determine the client's physiological stability and readiness for ambulation. It ensures the client's safety during the transfer and helps prevent any potential complications that may arise from getting out of bed. Administering oxygen, lying the client back down, or quickly moving the client to a chair without assessing vital signs can compromise the client's safety and may lead to adverse outcomes.
