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. A client is receiving discharge teaching about a new prescription for digoxin (Lanoxin). Which statement by the client indicates a need for further teaching?

• A. I should avoid foods high in potassium while taking this medication.
• B. I will check my pulse before taking the medication.
• C. I should avoid taking antacids simultaneously with this medication.
• D. I will take the medication at the same time every day.

Correct answer: A

Rationale: The correct answer is A because clients taking digoxin should avoid foods high in potassium. High potassium levels can potentiate the effects of digoxin, leading to toxicity. Choices B, C, and D are correct statements regarding digoxin administration. Checking the pulse before taking the medication helps monitor for signs of digoxin toxicity. Avoiding taking antacids simultaneously prevents interactions that may reduce digoxin absorption. Taking the medication at the same time every day helps maintain a consistent blood level, ensuring optimal therapeutic effects.

3. During a health assessment, a client who takes herbal supplements makes a statement indicating an understanding of their use. Which statement is most indicative of this understanding?

• A. I use garlic for my menopausal symptoms.
• B. I use ginger when I get car sick.
• C. I take ginkgo biloba for headaches.
• D. I take echinacea to control cholesterol.

Correct answer: C

Rationale: The correct answer is C because ginkgo biloba is commonly used to help with headaches, among other benefits. Choices A, B, and D are incorrect because garlic is not typically used for menopausal symptoms, ginger is mainly used for nausea and vomiting (not car sickness specifically), and echinacea is not known to control cholesterol.

4. A female UAP is assigned to take the vital signs of a client with pertussis for whom droplet precautions have been implemented. The UAP requests a change in assignment as she has not yet been fitted for a particulate filter mask. Which action should the nurse take?

• A. Advise the UAP to wear a standard face mask to take vital signs, and then get fitted for a filter mask before providing personal care
• B. Send the UAP to be fitted for a particulate filter mask immediately so she can provide care to this client
• C. Instruct the UAP that a standard mask is sufficient for the provision of care for the assigned client
• D. Before changing assignments, determine which staff members have fitted particulate filter masks

Correct answer: D

Rationale: The correct course of action for the nurse is to determine which staff members have already been fitted for particulate filter masks before changing assignments. This ensures safety and compliance with infection control protocols. Option A is incorrect as wearing a standard face mask before being fitted for a filter mask does not address compliance with droplet precautions. Option B is incorrect because the priority is to ensure all staff members have appropriate equipment before providing care. Option C is incorrect as a standard mask may not offer sufficient protection when dealing with clients under droplet precautions.

5. The healthcare provider prescribes 1,000 ml of Ringer's Lactate with 30 Units of Pitocin to run over 4 hours for a client who has just delivered a 10-pound infant by cesarean section. The tubing has been changed to a 20 gtt/ml administration set. The LPN/LVN plans to set the flow rate at how many gtt/min?

• A. 42 gtt/min
• B. 83 gtt/min
• C. 125 gtt/min
• D. 250 gtt/min

Correct answer: B

Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) ÷ Time (min) ÷ Drop factor (gtt/mL). In this case, 1000 mL ÷ 240 min ÷ 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.
