HESI Fundamentals Practice Test

Correct Answer: B

Rationale: Anticoagulants increase the risk of bleeding during surgery, which can lead to complications such as excessive bleeding and difficulty in achieving hemostasis. This poses a significant threat during a surgical procedure where controlling bleeding is crucial for a successful outcome. The other options (A, C, D) are not as critical as anticoagulants in terms of posing a threat for complications during surgery. Birth control pills, recently completing antibiotic therapy, and using laxatives do not directly impact bleeding risks during surgery compared to anticoagulants.

Correct Answer: A

Rationale: In the scenario where a nurse administers a medication outside the prescribed parameters, the immediate action should be to assess the client for any potential side effects of the medication. This is crucial to ensure the client's safety and well-being. By promptly assessing for side effects, the nurse can address any adverse reactions promptly and provide necessary interventions. Once the client's safety is ensured, documenting the client's responses, completing a medication error report, and assessing pain relief can follow as part of the broader response to the medication error. Choice B is not the first priority because the immediate concern is the potential harm from the incorrect dose. Choice C is also important but comes after ensuring the client's safety. Choice D focuses on the outcome rather than the immediate need to address any side effects of the medication.

Correct Answer: A

Rationale: The first intervention should be to check the drainage tubing for a kink. This step is crucial as any kinks in the tubing could obstruct urine flow, leading to a decreased output. By ensuring the tubing is free from any obstructions, the healthcare provider can address a potential mechanical issue causing the low output before considering other interventions. Reviewing the intake and output record may provide valuable information but should come after ensuring the tubing is clear. Notifying the healthcare provider can be done later if needed, but the immediate concern is to check for any obstructions. Giving the client water to drink may be necessary depending on the assessment findings, but addressing a possible kink in the tubing takes precedence.

Correct Answer: C

Rationale: Coughing, vomiting, and suctioning can precipitate displacement of the tip of the small-bore feeding tube upward into the esophagus, placing the client at increased risk for aspiration. Checking the sample of fluid withdrawn from the tube (after clearing the tube with 30 ml of air) for acidic (stomach) or alkaline (intestine) values is a more sensitive method for these tubes. The nurse should assess tube placement in this way before taking any other action to ensure the tube is still in the correct position and prevent potential complications. Choice A is incorrect because further assessment is needed due to the risk of tube displacement. Choice B is incorrect as stopping the feeding and involving the family is premature without confirming tube placement. Choice D is incorrect as injecting air and auscultating for gurgling is not the recommended method to confirm tube placement.

Correct Answer: D

Rationale: The most crucial assessment for the nurse to make after hemodialysis in a client with chronic renal failure is to check the client's fistula for bruit and thrill (D). This assessment is essential to ensure the patency of the fistula and adequate blood flow. Auscultating lung sounds (A), assessing blood pressure (B), and monitoring weight (C) are important assessments but are secondary to evaluating the fistula. Checking the fistula is vital as it directly impacts the effectiveness of the client's dialysis treatment and the patency of the vascular access, ensuring successful dialysis sessions.
