Nursing Elites

1. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?

• A. 400 mg
• B. 200 mg
• C. 1600 mg
• D. 100 mg

Correct answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

2. When providing oral care for an unconscious client, which of the following actions should the nurse take?

• A. Place the client in a lateral position with the head turned to the side before beginning the procedure.
• B. Insert a suction catheter before brushing the teeth.
• C. Use a soft-bristled toothbrush only with water.
• D. Brush the client's teeth while they are in a supine position.

Correct answer: A

Rationale: When providing oral care for an unconscious client, it is essential to place them in a lateral position with the head turned to the side before beginning the procedure. This positioning helps prevent aspiration by allowing fluids to drain out of the mouth, reducing the risk of choking or aspiration pneumonia. Inserting a suction catheter before brushing the teeth (Choice B) is not recommended as it can cause discomfort and increase the risk of oral tissue injury. Using a soft-bristled toothbrush only with water (Choice C) is not sufficient for effective oral care as toothpaste helps in removing plaque and bacteria. Brushing the client's teeth while they are in a supine position (Choice D) is not safe as it increases the risk of aspiration since fluids can easily enter the airway in this position.

3. A client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the LPN monitor closely while the client is taking this medication?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: The LPN should monitor potassium levels closely while the client is taking furosemide (Lasix) due to the medication's potential to cause hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Hypokalemia can result in serious complications such as cardiac dysrhythmias. Monitoring sodium levels (choice A) is important but not as critical as monitoring potassium in this context. Calcium (choice C) and magnesium (choice D) levels are not typically affected by furosemide and are not the priority for monitoring in this scenario.

4. A client has been sitting in a chair for 1 hour. Which of the following complications poses the greatest risk to the client?

• A. Decreased subcutaneous fat
• B. Muscle atrophy
• C. Pressure injury
• D. Fecal impaction

Correct answer: C

Rationale: The correct answer is C: Pressure injury. Prolonged sitting can lead to pressure injuries due to continuous pressure on certain body areas, reducing blood flow and causing tissue damage. While decreased subcutaneous fat, muscle atrophy, and fecal impaction are potential concerns, pressure injuries pose the greatest immediate risk as they can lead to serious complications such as tissue necrosis and infection if not addressed promptly. Decreased subcutaneous fat and muscle atrophy may develop over time with prolonged immobility but are not as acutely dangerous as a pressure injury. Fecal impaction, while uncomfortable and potentially serious, does not pose an immediate life-threatening risk compared to the development of a pressure injury.

5. A healthcare professional is teaching about home safety with a client. Which of the following instructions should the healthcare professional include?

• A. Unplug electronics by holding the plug
• B. Use electrical tape to secure extension cords next to baseboards on the floor
• C. To use a fire extinguisher, aim at the base of the flames
• D. Install slip-resistant rugs on tile floors

Correct answer: B

Rationale: The correct answer is to use electrical tape to secure extension cords next to baseboards on the floor. This practice helps prevent tripping and electrical hazards by keeping cords out of the way. Option A is incorrect as unplugging electronics should be done by holding the plug, not the cord itself. Option C is incorrect because when using a fire extinguisher, it should be aimed at the base of the flames, not at the top. Option D is not directly related to home safety teaching and may not be necessary for all clients, as it suggests an unnecessary change that may not improve safety.
