HESI Fundamentals Study Guide

Correct Answer: D

Rationale: In a closed wound drainage system, it is essential to maintain the drain in a dependent position to allow for proper drainage. Gravity aids in the flow of drainage, preventing fluid backflow or pooling. Avoiding pressing the container down to create a vacuum (Choice A) is crucial as it can lead to complications in the system. Wearing sterile gloves (Choice B) is important for infection control when handling the drainage system. Resetting the container with the drainage port closed (Choice C) is incorrect as it can cause spillage and contamination of the surrounding area.

Correct Answer: A

Rationale: The nurse should prioritize seeing the patient with a hip replacement on prolonged bed rest reporting chest pain and dyspnea first. This patient is at higher risk for deep vein thrombosis due to prolonged bed rest, which can lead to a life-threatening embolus. Chest pain and dyspnea could also indicate a potential pulmonary embolism, which requires immediate assessment and intervention. The other patients, while requiring care, do not present with symptoms that suggest an immediate life-threatening situation, making them lower priority at this time. Therefore, option A is the correct choice as it addresses a potentially critical condition that requires immediate attention.

Correct Answer: A

Rationale: Flushing the NG tube with water before and after medication administration is essential to ensure the tube is patent and prevent clogging. This action helps in clearing the tube and ensures that the medication is delivered properly. Administering medication with food (Choice B) may not be appropriate for all medications and can interfere with their absorption. Verifying tube placement by aspirating stomach contents (Choice C) is important but does not directly relate to ensuring proper medication administration. Diluting the medication with normal saline (Choice D) is not a standard practice for administering medications through an NG tube.

Correct Answer: A

Rationale: Observing the rate, depth, and character of the client's respirations is crucial after repositioning a client experiencing shortness of breath. This action provides immediate information about the client's respiratory status. Checking blood pressure (Choice B) is not the priority in this situation, as assessing respirations is more urgent. Assessing the pulse (Choice C) is also important but does not provide direct information about the client's respiratory status. Offering supplemental oxygen (Choice D) may be necessary based on the assessment of respirations, but it should not be the first action taken without assessing the client's breathing pattern.

Correct Answer: C

Rationale: The correct position for a postoperative client using an incentive spirometer is the Semi-Fowler's position. Placing the client in Semi-Fowler's or high-Fowler's position maximizes lung expansion and the effectiveness of the incentive spirometer. Side-lying may not provide optimal lung expansion. The supine position is not ideal for postoperative clients using incentive spirometers as it may limit lung expansion. The Trendelenburg position is not recommended due to potential complications postoperatively.
