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. A client has a stage 1 pressure ulcer on the right heel. Which of the following interventions should the nurse include in the plan?
- A. Apply a heat lamp to the area for 20 minutes each day.
- B. Change the dressing on the heel every 12 hours.
- C. Apply a transparent dressing over the heel.
- D. Use a water pressure mattress.
Correct answer: C
Rationale: Applying a transparent dressing over the heel is beneficial as it can protect the ulcer from friction and shear, and allow for continuous observation of the wound. This intervention promotes healing and prevents further damage to the skin. Choice A is incorrect because applying heat can increase the risk of tissue damage and should be avoided. Choice B is incorrect as changing the dressing every 12 hours may disrupt the wound healing process and is not necessary for a stage 1 pressure ulcer. Choice D is incorrect because using a water pressure mattress is not a specific intervention for a stage 1 pressure ulcer on the heel.
3. What action should be taken to prevent respiratory complications in a client who is postoperative?
- A. Encourage the use of an incentive spirometer.
- B. Restrict fluid intake.
- C. Place the client in a supine position.
- D. Administer a cough suppressant.
Correct answer: A
Rationale: Encouraging the use of an incentive spirometer is crucial in preventing respiratory complications postoperatively. The incentive spirometer helps the client perform deep breathing exercises, which can prevent atelectasis (lung collapse) and promote lung expansion. This, in turn, reduces the risk of respiratory complications such as pneumonia. Restricting fluid intake, placing the client in a supine position, and administering a cough suppressant are not appropriate actions for preventing respiratory complications in a postoperative client.
4. A healthcare professional is preparing to administer a subcutaneous injection. Which of the following actions should the healthcare professional take?
- A. Use a 1-inch needle.
- B. Insert the needle at a 90-degree angle.
- C. Use a tuberculin syringe.
- D. Aspirate before injecting.
Correct answer: B
Rationale: When administering a subcutaneous injection, it is important to insert the needle at a 90-degree angle to ensure proper medication delivery into the subcutaneous tissue. This angle helps prevent the medication from being injected too deeply or too superficially, ensuring optimal absorption and therapeutic effect. Choice A is incorrect because the needle length for a subcutaneous injection is typically shorter, around ⅝ to 1 inch. Choice C is incorrect as a tuberculin syringe is not commonly used for subcutaneous injections. Choice D is also incorrect as aspiration is not necessary for subcutaneous injections since there are minimal blood vessels in the subcutaneous tissue.
5. A healthcare professional is assessing a client who has chronic pain. Which of the following findings should the healthcare professional expect?
- A. Hypotension
- B. Tachycardia
- C. Hyperthermia
- D. Depression
Correct answer: D
Rationale: The correct answer is D: Depression. Chronic pain is often associated with psychological effects like depression. Patients with chronic pain may experience feelings of hopelessness, helplessness, and despair, which are characteristic of depression. While chronic pain can lead to changes in vital signs like increased blood pressure and heart rate, hypotension, tachycardia, or hyperthermia are not typically expected findings solely due to chronic pain. Therefore, the healthcare professional should be alert to signs of depression in clients with chronic pain and address these psychological impacts appropriately.
