HESI Fundamentals Exam

Correct Answer: B

Rationale: During a Weber test, the nurse should place an activated tuning fork in the middle of the client's forehead. This test is used to assess for lateralization of sound in a client with possible hearing issues. Choice A is incorrect because the Weber test does not involve delivering high-pitched sounds at random intervals. Choice C is incorrect as it describes the Rinne test, not the Weber test. Choice D is incorrect as whispering words into one ear is not part of the Weber test procedure.

Correct Answer: A

Rationale: Paralytic ileus is a condition where there is a temporary paralysis of the bowel, leading to absent bowel sounds and abdominal distention. This occurs because the bowel is not functioning properly to propel contents, resulting in a lack of bowel sounds. Absent bowel sounds with distention are typical findings in paralytic ileus. Hyperactive bowel sounds with pain are more indicative of increased motility and are not expected in paralytic ileus. Normal bowel sounds with cramping may be seen in other conditions, such as gastroenteritis. Diminished bowel sounds with tenderness are not typical findings in paralytic ileus.

Correct Answer: C

Rationale: The Z-track method is used to minimize tissue irritation by sealing the medication in the muscle. This technique helps prevent leakage of the medication into subcutaneous tissue, reducing the risk of irritation and staining at the injection site. Option A about decreasing the risk of injecting medication into a blood vessel is not correct as the primary purpose of the Z-track method is to prevent tissue irritation. Option B stating it delays medication absorption is incorrect as the Z-track method does not affect the rate of medication absorption. Option D mentioning it accelerates medication excretion is incorrect as the Z-track method does not impact medication excretion but rather focuses on minimizing tissue irritation.

Correct Answer: C

Rationale: The correct answer is C. This statement reflects the client's understanding of advance directives, as it indicates a specific preference regarding life-sustaining treatment. Advance directives enable individuals to outline their healthcare preferences, including decisions about treatments they wish to receive or avoid. Choice A mentions family members but doesn't address specific healthcare wishes; choice B focuses on the surgery rather than personal directives; choice D discusses doctor approval but lacks details about the directive itself.

Correct Answer: A

Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.
