HESI Fundamental Practice Exam

Correct Answer: B

Rationale: To ensure proper administration through a nasogastric tube, the LPN/LVN should flush the tube with 30 ml of water before and after medication administration. This action helps ensure the tube is patent, prevents clogging, and helps deliver the medication effectively. Checking the placement of the tube by auscultation (Choice A) is essential but does not directly relate to ensuring proper administration. Administering the medication with food (Choice C) may not always be appropriate for all medications and may not necessarily prevent nausea. Diluting the medication with normal saline (Choice D) is not a standard practice for all medications administered via an NG tube and may alter the medication's effectiveness.

Correct Answer: D

Rationale: Crepitus around the chest tube insertion site may indicate subcutaneous emphysema, a serious condition that requires immediate attention. It can be a sign of an air leak in the lung or surrounding tissues. Constant bubbling in the suction control chamber is expected in a functioning chest tube system as it indicates proper suction. Intermittent bubbling in the water seal chamber is also normal, showing that the system is functioning correctly, allowing air to escape but not re-enter. Drainage of 50 ml per hour is within the expected range for chest tube output and does not require immediate intervention unless there are other concerning signs such as rapid increase or a sudden change in color or consistency.

Correct Answer: A

Rationale: When providing mouth care for an unconscious client, the nurse should turn the client's head to the side. This action helps prevent aspiration by allowing any fluids to drain out of the mouth, reducing the risk of choking or aspiration pneumonia. Placing fingers into the client's mouth can be dangerous and may cause injury. Brushing the client's teeth only once a day may not be sufficient for proper oral hygiene care. Injecting mouth rinse into the center of the mouth is not recommended and can potentially lead to aspiration. Therefore, the correct action for the nurse to take is to turn the client's head to the side.

Correct Answer: A

Rationale: The correct answer is A. Changing the colostomy bag every day is not necessary; it should be changed as needed, usually every 3-7 days. This statement indicates a need for additional teaching as frequent changes can irritate the skin and are not typically required. Choices B, C, and D are all correct statements regarding colostomy care. Avoiding gas-producing foods, emptying the bag when it is one-third to one-half full, and taking care of the skin around the stoma are all essential aspects of colostomy care to prevent complications and maintain skin integrity.

Correct Answer: A

Rationale: Using a transfer belt if the client is unsteady is essential to provide added safety and support during ambulation. This device helps the nurse assist the client in maintaining balance and prevents falls. Walking beside the client without support (choice B) may not offer enough assistance for a frail, older adult who is unsteady. Encouraging the client to use a walker (choice C) could be helpful in some cases, but if the client is unsteady during ambulation, additional support like a transfer belt is more appropriate. Holding the client's arm for support (choice D) may not provide enough stability and safety compared to using a transfer belt.
