HESI Fundamental Practice Exam

Correct Answer: A

Rationale: When encountering an unfamiliar medication, the safest action for a nurse is to consult the medication reference book available on the unit. This resource provides accurate and detailed information about medications, including indications, dosages, side effects, and nursing considerations. Administering a medication without understanding it (choice B) can lead to medication errors and harm to the client. Asking a colleague for information (choice C) may not always provide accurate or up-to-date information. Contacting the provider (choice D) should be reserved for situations where immediate clarification is needed, but consulting the reference book is the initial step to gain knowledge and ensure safe medication administration.

Correct Answer: A

Rationale: Practice sessions are an effective psychomotor approach to learning for adolescents with ostomies as they involve hands-on practice of ostomy care skills, which can help reinforce learning through active engagement. Demonstrations (choice B) can be helpful in providing visual guidance but may not offer the same level of active participation and practice as practice sessions. Written instructions (choice C) may be useful for reference but may not be as effective in developing psychomotor skills. Group discussions (choice D) focus more on verbal exchange and may not directly address the need for hands-on skill development required in managing ostomies. Therefore, practice sessions are the most suitable method for enhancing psychomotor learning in this scenario.

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: A

Rationale: The correct technique for transferring a client from a bed to a chair to avoid back injuries is to bend at the knees while maintaining a wide stance and a straight back. This position ensures that the nurse uses leg muscles rather than the back muscles for lifting, reducing the risk of injury. Placing the client's hands on the nurse's shoulders and the nurse's hands under the client's axillae provides additional support and stability during the transfer. Using a mechanical lift may be appropriate for certain situations but is not necessary for a simple bed-to-chair transfer. Twisting at the waist while holding the client can lead to back strain or injury. Asking for assistance from another staff member is a good practice, but proper body mechanics should still be followed to ensure safe client handling.

Correct Answer: A

Rationale: The correct location to auscultate the aortic valve is the second intercostal space to the right of the sternum. This area corresponds to the aortic valve area where aortic valve sounds are best heard. Choices B, C, and D are incorrect for auscultating the aortic valve. The fifth intercostal space to the left of the sternum is where the mitral valve is best heard, the third intercostal space to the left of the sternum is where the pulmonic valve is best heard, and the fourth intercostal space at the midclavicular line is where the tricuspid valve is best auscultated.
