HESI Fundamental Practice Exam

Correct Answer: A

Rationale: The correct answer is A. Changing the colostomy bag every day is not necessary; it should be changed as needed, usually every 3-7 days. This statement indicates a need for additional teaching as frequent changes can irritate the skin and are not typically required. Choices B, C, and D are all correct statements regarding colostomy care. Avoiding gas-producing foods, emptying the bag when it is one-third to one-half full, and taking care of the skin around the stoma are all essential aspects of colostomy care to prevent complications and maintain skin integrity.

Correct Answer: A

Rationale: The correct answer is A. Clients taking warfarin need to be consistent with their vitamin K intake to maintain a balance in blood clotting. Avoiding foods high in vitamin K is essential as they can interfere with the medication's effectiveness. Choices B, C, and D are all correct statements regarding warfarin therapy. Regular blood testing to monitor INR levels ensures the medication is working effectively, taking the medication at the same time daily maintains a consistent level in the bloodstream, and using a soft toothbrush helps prevent gum bleeding due to warfarin's anticoagulant effects.

Correct Answer: A

Rationale: The correct action for the nurse to take is to remove the client's stockings at least once during each shift. This is important to inspect the skin and prevent complications such as pressure injuries or impaired circulation. Rolling the top of the stockings down can compromise their effectiveness in preventing blood clots. Seating the client in a chair prior to applying stockings is not directly related to the care of anti-embolic stockings. Measuring the length of the client's leg from the heel to the gluteal fold is not necessary for the application or care of knee-length anti-embolic stockings.

Correct Answer: A

Rationale: The correct instruction for electrical safety is to avoid taping electrical cords to the floor. Taping cords can create tripping hazards, leading to falls and potential injuries. Choice B, cleaning electrical equipment before disconnection, is not directly related to electrical safety but rather to equipment maintenance. Choice C, covering exposed wires with tape before use, is incorrect as exposed wires should be properly insulated and repaired by a qualified professional. Choice D, disconnecting electrical equipment by grasping the plug, is unsafe and can lead to electrical shocks. It is always recommended to unplug devices by holding the plug itself, not by pulling the cord.

Correct Answer: C

Rationale: Choice C is the correct answer because it demonstrates that the client understands the importance of communicating with the nurse if the pain persists while using the PCA device. This is crucial as it ensures proper pain management and monitoring. Choices A and B are incorrect because delaying the use of the device until necessary or being cautious about pushing the button too much do not necessarily reflect understanding of using the PCA device effectively. Choice D is incorrect as having someone else, like an adult child, push the dose button goes against the principle of the client self-administering the medication through the PCA device.
