HESI LPN
HESI Fundamental Practice Exam
1. The nurse is caring for a client with a nasogastric (NG) tube. Which action should the LPN/LVN take to maintain patency of the tube?
- A. Flush the tube with 30 ml of water before and after medication administration.
- B. Secure the tube to the client's gown.
- C. Check the placement of the tube by auscultation.
- D. Irrigate the tube with normal saline every shift.
Correct answer: A
Rationale: The correct action to maintain patency of a nasogastric (NG) tube is to flush the tube with water before and after medication administration. Flushing helps prevent clogging and ensures that the tube remains clear for proper functioning. Securing the tube to the client's gown (Choice B) is important for stability but does not directly address tube patency. Checking the placement of the tube by auscultation (Choice C) is crucial for verifying correct placement but does not specifically relate to maintaining tube patency. Irrigating the tube with normal saline every shift (Choice D) is not a routine practice for maintaining tube patency and can lead to electrolyte imbalances.
2. What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?
- A. Assess the client's respiratory rate and effort.
- B. Measure the client's oxygen saturation level.
- C. Monitor the client's arterial blood gas levels.
- D. Check the client's blood pressure.
Correct answer: B
Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.
3. A client has left lower atelectasis. In which of the following positions should the nurse place the client for postural drainage?
- A. Supine and low Fowler's position
- B. Right lateral in Trendelenburg position
- C. Side lying with the right side of the chest elevated
- D. Prone with pillows under the extremities
Correct answer: B
Rationale: Postural drainage is a technique used to help remove secretions from specific lung segments. For left lower atelectasis, placing the client in the right lateral Trendelenburg position is most effective. This position helps target the affected area, using gravity to assist in drainage. Placing the client in a supine or low Fowler's position (Choice A) may not effectively target the affected area. Side lying with the right side of the chest elevated (Choice C) would not utilize gravity for optimal drainage. Placing the client prone with pillows under the extremities (Choice D) is not ideal for postural drainage of the left lower lobe.
4. Which patient will lead the nurse to select a nursing diagnosis of Impaired physical mobility for a care plan?
- A. A patient who is completely immobile
- B. A patient who is not completely immobile
- C. A patient at risk for single-system involvement
- D. A patient who is at risk for multisystem problems
Correct answer: B
Rationale: The correct answer is B because the nursing diagnosis of Impaired physical mobility is appropriate for a patient who has some limitations in mobility but is not completely immobile. Choice A is incorrect as a patient who is completely immobile would not have impaired physical mobility but rather no physical mobility at all. Choices C and D are also incorrect as they do not directly relate to the defining characteristics of Impaired physical mobility, which involve limitations in movement and physical activity.
5. The healthcare provider is caring for a client receiving total parenteral nutrition (TPN). Which laboratory value should be monitored closely to assess for complications?
- A. Serum sodium
- B. Serum calcium
- C. Blood urea nitrogen (BUN)
- D. Blood glucose
Correct answer: D
Rationale: The correct answer is D: Blood glucose. Monitoring blood glucose levels is crucial for clients receiving total parenteral nutrition (TPN) due to the high glucose content in TPN solutions. TPN delivers essential nutrients, including glucose, directly into the bloodstream. Clients on TPN are at risk of developing hyperglycemia due to the concentrated glucose infusion. Therefore, close monitoring of blood glucose levels is necessary to detect and prevent hyperglycemia-related complications such as osmotic diuresis, hyperosmolarity, and electrolyte imbalances. While serum sodium, serum calcium, and blood urea nitrogen (BUN) levels are important parameters in various clinical scenarios, they are not specifically associated with TPN administration. These values are not the primary indicators to assess for complications in clients receiving TPN.
