Fundamentals of Nursing HESI

Correct Answer: C

Rationale: When preparing to insert an IV catheter, stroking the extremity before insertion helps to visualize veins, making it easier to locate a suitable vein for catheter insertion. Choosing the most distal site on the extremity is correct because veins more distal are preferred for IV catheter insertion. Applying a cool compress to the extremity before insertion is unnecessary and not a standard practice. Placing the tourniquet below the proposed insertion site is incorrect; the tourniquet should be placed above the proposed insertion site to help engorge the veins for easier visualization and access.

Correct Answer: B

Rationale: The correct answer is to emphasize emptying the child's mouth in any case of possible poisoning. This action is crucial to prevent further ingestion of the poisonous substance. Choice A is incorrect because calling the Poison Control Center should be one of the first steps, not waiting until the situation is identified. Choice C is incorrect as moving the child may spread or exacerbate the effects of the toxic substance. Choice D is incorrect because inducing vomiting can be harmful if the poison is a hydrocarbon, as it may lead to aspiration.

Correct Answer: B

Rationale: The correct answer is B: Moist sterile non-adherent dressing. A moist sterile non-adherent dressing is suitable for covering a neural tube defect and would not require further intervention. This type of dressing helps prevent the dressing from sticking to the wound, minimizing trauma during dressing changes. Choice A, Telfa dressing with antibiotic ointment, is not ideal for a neural tube defect as the ointment may not be necessary and can complicate wound care. Choice C, dry sterile dressing that is occlusive, is not recommended for a neural tube defect as it may not provide the necessary environment for proper wound healing. Choice D, sterile occlusive pressure dressing, is excessive for a neural tube defect and may cause unnecessary pressure on the wound site.

Correct Answer: D

Rationale: The priority action for the nurse is to address the client's immediate physiological need for comfort and pain relief during the dressing change. Administering pain medication 45 minutes before the procedure can help alleviate the pain experienced by the client. Encouraging relaxation techniques (choice A) is beneficial but may not provide sufficient pain relief during the dressing change. Educating about the importance of pain management (choice B) is relevant but does not address the immediate need for pain relief. Assisting the client to a comfortable position (choice C) is helpful but does not directly address the client's pain concern during the dressing change. Administering pain medication is the most direct and effective intervention to ensure optimal client comfort and compliance with necessary procedures.

Correct Answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.
