LPN Fundamentals Practice Questions
1. A healthcare provider is caring for a client who has acute renal failure. Which of the following laboratory results should the healthcare provider expect?
- A. Decreased blood urea nitrogen (BUN)
- B. Decreased creatinine
- C. Increased potassium
- D. Increased calcium
Correct answer: C
Rationale: In acute renal failure, the kidneys are unable to excrete potassium efficiently, which can lead to hyperkalemia. As a result, an increased potassium level is a common finding in clients with acute renal failure. Hyperkalemia can have serious cardiac effects, making it essential for healthcare providers to monitor and manage potassium levels closely in clients with renal impairment. Choices A, B, and D are incorrect because in acute renal failure, blood urea nitrogen (BUN) and creatinine levels typically rise due to decreased renal function. Calcium levels are more likely to be decreased in acute renal failure due to impaired activation of vitamin D and subsequent decreased calcium absorption.
2. What is the primary benefit of using electronic health records (EHRs) in healthcare?
- A. EHRs eliminate the need for paper records.
- B. EHRs ensure complete patient confidentiality.
- C. EHRs improve the accuracy of patient information.
- D. EHRs reduce the time spent on documentation.
Correct answer: C
Rationale: The primary benefit of using electronic health records (EHRs) in healthcare is that they improve the accuracy and completeness of patient information. By utilizing EHRs, healthcare providers have access to more reliable and up-to-date patient data, which leads to better patient care outcomes. This improved accuracy enables healthcare professionals to make better-informed decisions and provide more effective treatments, ultimately enhancing patient safety and quality of care.
3. A client is receiving enteral feedings through an NG tube. Which of the following actions should be taken to prevent aspiration?
- A. Monitor gastric residuals every 4 hours.
- B. Position the client in a semi-Fowler's position.
- C. Check for tube placement by auscultating air after feeding.
- D. Warm the formula to body temperature before feeding.
Correct answer: A
Rationale: Monitoring gastric residuals every 4 hours is essential to assess the stomach's ability to empty properly, reducing the risk of aspiration. It helps in determining if the feedings are being tolerated by the client and if adjustments are needed in the feeding regimen. Positioning the client in a semi-Fowler's position helps prevent reflux and aspiration by promoting proper digestion and emptying of the stomach contents. Checking for tube placement by auscultating air after feeding confirms correct tube placement in the stomach. Warming the formula to body temperature before feeding enhances client comfort but does not directly prevent aspiration. Therefore, the correct answer is to monitor gastric residuals to prevent aspiration, as it directly assesses the stomach's ability to empty properly and the tolerance of the feedings.
4. When assessing a client with diabetes mellitus experiencing DKA, which of the following findings should the nurse expect?
- A. Tremors
- B. Urine retention
- C. Kussmaul respirations
- D. Bradypnea
Correct answer: C
Rationale: Kussmaul respirations are a type of deep and labored breathing pattern associated with severe metabolic acidosis, commonly observed in diabetic ketoacidosis (DKA). In DKA, the body tries to compensate for the acidic environment by increasing the respiratory rate, resulting in Kussmaul respirations. This helps eliminate excess carbon dioxide and reduce the acidity of the blood. Tremors (Choice A) are not typically associated with DKA. Urine retention (Choice B) is not a common finding in DKA; in fact, clients with DKA often have polyuria due to the osmotic diuresis caused by high blood glucose levels. Bradypnea (Choice D), which is abnormally slow breathing rate, is not a characteristic finding in DKA where the respiratory rate is usually increased to compensate for metabolic acidosis.
5. A healthcare professional is preparing to administer a cleansing enema to a client. Which of the following actions should the healthcare professional plan to take?
- A. Insert the rectal tube 15.2 cm (6 inches) into the client's rectum
- B. Wear clean gloves before inserting the tubing
- C. Position the client on their left side
- D. Hold the solution bag 91 cm (36 inches) above the client's rectum
Correct answer: C
Rationale: Positioning the client on their left side is crucial when administering an enema as it helps facilitate the flow of the solution into the sigmoid and descending colon. This position allows gravity to assist in the process. Placing the client on the left side is a standard practice to promote optimal outcomes during the procedure. Choices A, B, and D are incorrect. Choice A provides a specific measurement for the insertion depth of the rectal tube, which is not typically necessary to include in the plan of action. Choice B is essential but not specific to enema administration. Choice D mentions holding the solution bag without specifying the correct height, which should typically be around 18-24 inches above the rectum for a cleansing enema.
