HESI LPN
Fundamentals HESI
1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?
- A. Blood glucose level
- B. Prothrombin time (PT) and INR
- C. Serum potassium level
- D. Serum creatinine level
Correct answer: B
Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.
2. A nurse is preparing to provide tracheostomy care for a client. Which of the following actions should the nurse take first?
- A. Perform hand hygiene
- B. Identify the client using two identifiers
- C. Prepare the sterile field
- D. Don sterile gloves
Correct answer: A
Rationale: Performing hand hygiene is essential before any direct patient care procedure to prevent the spread of infection. Proper hand hygiene helps reduce the risk of introducing harmful microorganisms to the client, especially when dealing with a procedure like tracheostomy care. Identifying the client, preparing the sterile field, and donning sterile gloves are all important steps in tracheostomy care, but hand hygiene precedes them to maintain asepsis and ensure patient safety.
3. The nurse is assessing a 17-year-old female client with bulimia. Which of the following laboratory reports would the nurse anticipate?
- A. Increased serum glucose
- B. Decreased albumin
- C. Decreased potassium
- D. Increased sodium retention
Correct answer: C
Rationale: The correct answer is C, 'Decreased potassium.' Clients with bulimia often have decreased potassium levels due to frequent vomiting, which causes a loss of this essential electrolyte. This loss can lead to various complications such as cardiac arrhythmias. Option A, 'Increased serum glucose,' is not typically associated with bulimia. Option B, 'Decreased albumin,' is more related to malnutrition or liver disease rather than bulimia. Option D, 'Increased sodium retention,' is not a common finding in clients with bulimia; instead, they may experience electrolyte imbalances like hyponatremia due to purging behaviors.
4. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?
- A. 11,000 units.
- B. 13,000 units.
- C. 15,000 units.
- D. 17,000 units.
Correct answer: A
Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
5. The nurse is having difficulty reading the healthcare provider's written order that was written right before the shift change. What action should be taken?
- A. Leave the order for the oncoming staff to follow up
- B. Contact the charge nurse for an interpretation
- C. Ask the pharmacy for assistance in interpretation
- D. Call the provider for clarification
Correct answer: D
Rationale: The nurse should call the provider for clarification. In situations where there is difficulty reading an order, it is crucial to directly contact the healthcare provider to ensure the correct order is understood and followed. Leaving the order for the oncoming staff (Choice A) may lead to misunderstandings and errors. Contacting the charge nurse (Choice B) may cause delays as they may also need to contact the provider. Asking the pharmacy (Choice C) is not the most direct and immediate action in this scenario, as the provider is the one who can provide immediate clarification.
