Nursing Elites

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. A client has been admitted to the hospital with severe diarrhea. The nurse should monitor the client for which complication?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.

3. The LPN/LVN is assisting with the care of a client who has just had a liver biopsy. What position should the nurse place the client in immediately following the procedure?

• A. Supine with the right arm raised above the head
• B. Supine with the head of the bed elevated
• C. Right side-lying with a pillow under the costal margin
• D. Left side-lying with the head of the bed flat

Correct answer: C

Rationale: The correct position for a client immediately following a liver biopsy is right side-lying with a pillow under the costal margin. This position helps prevent bleeding by applying pressure to the biopsy site. Placing the client supine with the right arm raised above the head (Choice A) or supine with the head of the bed elevated (Choice B) are not ideal positions for post-liver biopsy care as they do not provide the necessary pressure to the biopsy site. Left side-lying with the head of the bed flat (Choice D) is also not recommended as it does not assist in preventing bleeding after a liver biopsy.

4. A healthcare professional is administering 1 L of 0.9% sodium chloride to a client who is postoperative and has fluid-volume deficit. Which of the following changes should the healthcare professional identify as an indication that the treatment was successful?

• A. Increase in hematocrit
• B. Increase in respiratory rate
• C. Decrease in heart rate
• D. Decrease in capillary refill time

Correct answer: C

Rationale: Fluid-volume deficit causes tachycardia. With correction of the imbalance, the heart rate should return to the expected range. An increase in hematocrit (Choice A) would indicate hemoconcentration, not a successful fluid replacement. An increase in respiratory rate (Choice B) could indicate respiratory distress or hypoxia, not improvement in fluid volume status. A decrease in capillary refill time (Choice D) may indicate improved peripheral perfusion but is not a direct indicator of fluid replacement success.

5. A nurse is collecting a blood pressure reading from a client who is sitting in a chair. The nurse determines that the client's BP is 158/96 mmHg. Which of the following actions should the nurse take?

• A. Ensure that the width of the BP cuff is appropriate for the client's arm circumference.
• B. Reposition the client supine and recheck their BP.
• C. Recheck the client's BP and measure their other arm for comparison.
• D. Request that another nurse check the client's BP in 30 minutes.

Correct answer: C

Rationale: When a nurse obtains a blood pressure reading that is elevated, the appropriate action is to recheck the client's BP and measure the other arm for comparison. This step helps ensure accuracy by ruling out errors like improper cuff size, positioning, or equipment malfunction. Repositioning the client supine is not necessary unless the client shows signs of distress or symptoms. Ensuring the appropriate cuff width is important for accurate readings but does not address the immediate need to confirm the current BP. Requesting another nurse to check the BP in 30 minutes delays immediate action and does not address the need for verification and comparison of the current reading.
