HESI Fundamentals Exam

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: In this scenario, it is crucial to prioritize the comfort of the child. By examining the mouth last, discomfort is minimized, and the child is given the opportunity to settle down. Choosing to examine the mouth first may escalate the distress of the child further. While reassuring the child is important, in this case, addressing the physical discomfort before providing emotional reassurance is more effective. Offering a pacifier may provide some comfort, but addressing the immediate physical discomfort by examining the mouth last is the most appropriate action to help the child settle down after the procedure.

Correct Answer: B

Rationale: The nurse should address the client's lack of understanding regarding the need for surgery first. Ensuring that the client comprehends the rationale for the procedure is essential for informed consent. Choices A, C, and D, while important, do not directly impact the client's understanding of the necessity of the surgery and can be addressed after clarifying the reason for the procedure.

Correct Answer: A

Rationale: The correct action the nurse should take first is to auscultate bowel sounds. This step is crucial to assess bowel activity before proceeding with palpation or administering medications. Assessing bowel sounds can provide valuable information about bowel motility and potential obstructions. Administering an antiemetic or offering pain medication may be necessary but should come after assessing bowel sounds to ensure appropriate treatment. Palpating the abdomen should be avoided initially to prevent potential discomfort or complications, especially if there is suspected abdominal pathology.
