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 client with an NG tube is receiving intermittent feedings through an open system. Which of the following actions should the nurse take first?

• A. Rinse the feeding bag with water between feedings
• B. Tell the client to keep the head of the bed elevated at least 30°
• C. Make sure the enteral formula is at room temperature
• D. Wipe the top of the formula can with alcohol

Correct answer: B

Rationale: The correct answer is to tell the client to keep the head of the bed elevated at least 30°. Elevating the head of the bed prevents aspiration of the enteral formula, which is a priority in caring for a client with an NG tube. This action helps in reducing the risk of complications such as pneumonia. Choices A, C, and D are incorrect. While rinsing the feeding bag, ensuring the enteral formula temperature, and maintaining cleanliness are important aspects of enteral feeding care, the priority is to prevent aspiration by keeping the head of the bed elevated. These actions can be implemented after ensuring the client's safety by maintaining the correct bed position.

3. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

• A. Monitor serum calcium levels.
• B. Monitor serum potassium levels.
• C. Monitor serum sodium levels.
• D. Monitor serum magnesium levels.

Correct answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.

4. A home health nurse is discussing the dangers of carbon monoxide poisoning with a client. Which of the following information should the nurse include?

• A. Carbon monoxide does not have a distinct odor.
• B. Water heaters should be inspected every 5 years.
• C. The lungs are not damaged from carbon monoxide inhalation.
• D. Carbon monoxide binds with hemoglobin in the body.

Correct answer: D

Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.

5. When planning to perform passive range-of-motion exercises for a client, what action should a healthcare professional take?

• A. Repeat each joint motion five times during each session.
• B. Perform the exercises quickly to save time.
• C. Focus only on the most affected joints.
• D. Assess the client's range of motion before starting.

Correct answer: A

Rationale: The correct answer is to repeat each joint motion five times during each session. Repetition is crucial to maintaining joint flexibility and muscle function. By ensuring each joint motion is repeated, the client can benefit fully from the passive range-of-motion exercises. Choice B is incorrect because quick performance may compromise technique and risk injury. Choice C is incorrect as neglecting less affected joints can lead to imbalances and hinder overall progress. Choice D is incorrect as assessing the client's range of motion beforehand is vital, but it is not the immediate action to take during the exercise session.
