Nursing Elites

1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?

• A. 13 ml/hour
• B. 63 ml/hour
• C. 80 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

2. A healthcare professional is obtaining the blood pressure in a client's lower extremity. Which of the following actions should the healthcare professional take?

• A. Place the bladder of the cuff over the posterior aspect of the thigh
• B. Use a smaller cuff designed for lower extremities
• C. Place the cuff around the client's ankle
• D. Ensure the cuff is positioned above the knee

Correct answer: A

Rationale: When measuring blood pressure in the lower extremity, the bladder of the cuff should be placed over the posterior aspect of the thigh. This positioning ensures an accurate measurement. Placing the cuff around the ankle (Choice C) or above the knee (Choice D) would not provide an accurate blood pressure reading in the lower extremity. Using a smaller cuff designed for lower extremities (Choice B) is not appropriate as the standard cuff size should be used with the bladder placed over the posterior aspect of the thigh.

3. A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)

• A. 400 mL/hr
• B. 200 mL/hr
• C. 300 mL/hr
• D. 250 mL/hr

Correct answer: A

Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.

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. A client in the emergency department is being cared for by a nurse and has abdominal trauma. Which of the following assessment findings should the nurse identify as an indication of hypovolemic shock?

• A. Tachycardia
• B. Elevated blood pressure
• C. Warm, dry skin
• D. Decreased respiratory rate

Correct answer: A

Rationale: Tachycardia is a hallmark sign of hypovolemic shock. When a client experiences significant blood loss, the body compensates by increasing the heart rate to maintain adequate perfusion to vital organs. Elevated blood pressure is not typically seen in hypovolemic shock; instead, hypotension is a more common finding. Warm, dry skin is characteristic of neurogenic shock, not hypovolemic shock. Decreased respiratory rate is not a typical manifestation of hypovolemic shock, as the body usually tries to increase respiratory effort to improve oxygenation in response to hypovolemia.
