HESI Practice Test for Fundamentals

Correct Answer: D

Rationale: When using wrist restraints, it is important to allow room for two fingers to fit between the client's skin and the restraints. This practice ensures proper circulation and comfort for the client while still providing the necessary level of security. Choice A is incorrect because removing restraints every 4 hours may compromise the effectiveness of restraint use. Choice B is incorrect as restraints should not be attached to the side of the bed where they could cause harm or be tampered with by the client. Choice C is incorrect because allowing minimal movement may lead to discomfort and compromise proper circulation.

Correct Answer: A

Rationale: The correct action when a client suddenly grabs at their neck and appears frightened is to ask if they are choking. This allows the nurse to gather more information from the client directly. Performing abdominal thrusts (choice B) should only be done if the client is unable to speak, cough, or breathe. Calling for emergency help (choice C) should be done after assessing the situation and confirming choking. Checking the client's airway (choice D) is important but should come after confirming that the client is choking.

Correct Answer: A

Rationale: The correct first step in using a fire extinguisher is to remove the safety pin. This action enables the extinguisher to be activated and used effectively. Choice B, aiming the extinguisher at the base of the fire, comes after removing the safety pin. Choice C, squeezing the handle to release the extinguishing agent, and choice D, sweeping the extinguisher from side to side, are subsequent steps in using a fire extinguisher and should follow removing the safety pin.

Correct Answer: D

Rationale: In this scenario, the priority is to ensure the client has a clear airway to facilitate breathing. After verifying unresponsiveness and calling for help, the nurse should open the client's airway to aid in maintaining ventilation. Checking the carotid pulse (Choice A) may be important but comes after ensuring a clear airway. Delivering abdominal thrusts (Choice B) is indicated for choking, not for an unresponsive client. Giving rescue breaths (Choice C) is also important but only after the airway has been established.

Correct Answer: B

Rationale: The correct answer is B. Gently applying pressure to the front part of the ear after administering drops helps with absorption. Pulling the ear down and back is a correct technique for adults. Snugly inserting the nozzle of the ear drop bottle or placing a cotton ball all the way into the ear canal is unnecessary and can potentially cause harm or discomfort. Therefore, choices A, C, and D are incorrect.
