HESI Fundamentals Study Guide
1. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?
- A. Serum potassium
- B. Serum calcium
- C. Serum albumin
- D. Serum sodium
Correct answer: C
Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.
2. The patient diagnosed with athlete's foot (tinea pedis) states that he is relieved because it is only athlete's foot, and it can be treated easily. Which information about this condition should the nurse consider when formulating a response to the patient?
- A. It is contagious with frequent recurrences.
- B. It is most helpful to air-dry feet after bathing.
- C. It is treated with salicylic acid.
- D. It is caused by lice.
Correct answer: A
Rationale: Athlete's foot, also known as tinea pedis, is a contagious fungal infection that can easily spread to other body parts, particularly the hands. It often recurs if not properly treated, making choice A the correct answer. Choices B and C are incorrect because while it is beneficial to air-dry feet after bathing to prevent moisture buildup, athlete's foot is commonly treated with antifungal medications, not salicylic acid. Choice D is incorrect because athlete's foot is caused by a fungal infection, not lice.
3. A nurse is providing care to a client who has an indwelling urinary catheter. Which of the following actions should the nurse take to prevent catheter-associated urinary tract infections (CAUTIs)?
- A. Irrigate the catheter with sterile water daily.
- B. Empty the catheter bag every 8 hours.
- C. Clean the perineal area with antiseptic solution daily.
- D. Secure the catheter to the client's thigh.
Correct answer: D
Rationale: Securing the catheter to the client's thigh is the correct action to prevent CAUTIs. By securing the catheter, movement is minimized, reducing the risk of introducing bacteria into the urinary tract. Choice A is incorrect because routine irrigation of the catheter is not recommended as it can increase the risk of infection. Choice B is incorrect as emptying the catheter bag every 8 hours is important for proper drainage but does not directly prevent CAUTIs. Choice C is incorrect because cleaning the perineal area with antiseptic solution does not address the main source of CAUTIs related to catheter care.
4. 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.
5. What is the most important action for preventing infection in a client with a central venous catheter?
- A. Changing the catheter dressing every 72 hours.
- B. Flushing the catheter with heparin solution daily.
- C. Ensuring the catheter is clamped when not in use.
- D. Maintaining sterile technique when handling the catheter.
Correct answer: D
Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.
