1. 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.

2. The nurse is preparing to administer a medication through a nasogastric (NG) tube. Which action should the LPN/LVN take to ensure proper administration?

• A. Check the placement of the tube by auscultation.
• B. Flush the tube with 30 ml of water before and after medication administration.
• C. Administer the medication with food to prevent nausea.
• D. Dilute the medication with normal saline before administration.

Correct answer: B

Rationale: To ensure proper administration through a nasogastric tube, the LPN/LVN should flush the tube with 30 ml of water before and after medication administration. This action helps ensure the tube is patent, prevents clogging, and helps deliver the medication effectively. Checking the placement of the tube by auscultation (Choice A) is essential but does not directly relate to ensuring proper administration. Administering the medication with food (Choice C) may not always be appropriate for all medications and may not necessarily prevent nausea. Diluting the medication with normal saline (Choice D) is not a standard practice for all medications administered via an NG tube and may alter the medication's effectiveness.

3. The nurse is assessing body alignment for a patient who is immobilized. Which patient position will the nurse use?

• A. Supine position
• B. Lateral position
• C. Lateral position with positioning supports
• D. Supine position with no pillow under the patient's head

Correct answer: B

Rationale: When assessing body alignment for an immobilized patient, the nurse should use the lateral position. This position helps in assessing alignment and preventing complications such as pressure ulcers. The supine position (Choice A) may not provide an accurate assessment of body alignment in an immobilized patient. While a lateral position with positioning supports (Choice C) may be used for comfort, it is not specifically for assessing body alignment. Using the supine position without a pillow under the patient's head (Choice D) is not ideal for assessing body alignment in an immobilized patient as it may not accurately reflect the patient's overall alignment.

4. What intervention should be implemented by the LPN to reduce the risk of aspiration in a client with a nasogastric tube receiving continuous enteral feedings?

• A. Elevate the head of the bed to 30-45 degrees.
• B. Check residual volumes every 4 hours.
• C. Verify tube placement every shift.
• D. Flush the tube with water every 4 hours.

Correct answer: A

Rationale: Elevating the head of the bed to 30-45 degrees is crucial in reducing the risk of aspiration because it helps keep the gastric contents lower than the esophagus, thereby promoting proper digestion and preventing reflux. This position also aids in reducing the likelihood of regurgitation and aspiration of gastric contents. Checking residual volumes every 4 hours is important for monitoring feeding tolerance but does not directly address the risk of aspiration. Verifying tube placement every shift is essential for ensuring the tube is correctly positioned within the gastrointestinal tract but does not directly reduce the risk of aspiration. Flushing the tube with water every 4 hours may help maintain tube patency and prevent clogging, but it does not specifically address the risk of aspiration associated with nasogastric tube feedings.

5. What are the correct steps used for abdominal assessment?

• A. Inspection, auscultation, percussion, palpation
• B. Palpation, inspection, auscultation, percussion
• C. Percussion, palpation, inspection, auscultation
• D. Auscultation, palpation, percussion, inspection

Correct answer: A

Rationale: The correct order for abdominal assessment is inspection, auscultation, percussion, and palpation. Inspection allows the nurse to visually assess the abdomen for any abnormalities or distension. Auscultation follows to listen for bowel sounds and vascular sounds. Percussion helps to assess the density of underlying structures and detect any abnormal masses. Palpation is performed last to assess tenderness, organ size, and detect any masses. Choices B, C, and D have the steps in the incorrect order, making them the wrong choices.
