HESI Nutrition Exam

Correct Answer: A

Rationale: To prevent unnecessary hypoxia during suctioning of a tracheostomy, the nurse must apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia by removing too much oxygen from the patient. Maintaining a sterile technique (choice B) is important to prevent infection but does not directly relate to preventing hypoxia. Lubricating the catheter tip (choice C) helps with the insertion process but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not contribute to preventing hypoxia.

Correct Answer: D

Rationale: For a client with a percutaneous endoscopic gastrostomy (PEG) tube, flushing the tube adequately with water before and after use is essential. This action helps prevent clogging and ensures the proper administration of feedings and medications. Choice A is incorrect because pulverizing all medications into a powdery condition is not necessary for PEG tube administration. Choice B is incorrect as squeezing the tube to break up stagnant liquids may damage the tube. Choice C is incorrect because cleansing the skin around the tube daily with hydrogen peroxide can be too harsh and lead to skin irritation.

Correct Answer: D

Rationale: The correct sequence for initiating enteral feeding includes verifying tube placement to ensure safety, checking the residual feeding contents to prevent complications, and then administering the feeding. Limiting protein intake is not a step in the sequence for initiating enteral feeding. Protein intake may be adjusted based on the patient's specific nutritional needs, but it is not a part of the immediate sequence for initiating the feeding. Therefore, option D is the correct answer. Options A, B, and C are essential steps to ensure the safe and effective administration of enteral feeding.

Correct Answer: C

Rationale: The correct answer is C: Chloride. Chloride levels are typically low in cases of hyponatremia, as it often accompanies sodium loss. Magnesium (choice A) is not directly related to hyponatremia. Calcium (choice B) and Potassium (choice D) levels are usually not significantly affected by hyponatremia, making them less likely to be below the expected reference range in this scenario.

Correct Answer: B

Rationale: In this scenario where the upper leg dressing becomes saturated with blood post-femoral popliteal bypass, the nurse's first action should be to apply pressure at the bleeding site. Applying pressure is essential to control hemorrhage and prevent further blood loss. Choice A is incorrect as wrapping the leg with elastic bandages would not address the immediate issue of controlling the bleeding. Choice C is incorrect because reinforcing the dressing and elevating the leg should come after controlling the bleeding. Choice D is incorrect as removing the dressings and re-dressing the incision should only be done after the bleeding is under control to prevent excessive blood loss.
