The nurse is caring for a client who receives a prescription for valproic acid in which the maximum safe dosage is 60 mg/kg/day.
How many mg/day is the maximum safe dosage for a client who weighs 176 pounds? (Enter numerical value only.).
4012 mg/day.
4800 mg/day.
3520 mg/day.
6171 mg/day
The Correct Answer is B
Choice A rationale:
4012 mg/day is not the correct answer. To calculate the maximum safe dosage of valproic acid, you need to convert the client's weight from pounds to kilograms. The client's weight in kilograms can be calculated by dividing the weight in pounds by 2.2. Therefore, 176 pounds divided by 2.2 equals 80 kilograms. The maximum safe dosage is 60 mg/kg/day, so 60 mg multiplied by 80 kg equals 4800 mg/day.
Choice B rationale:
Step 1: Convert the client’s weight from pounds to kilograms. We know that 1 kg is approximately equal to 2.2 pounds. So, we have:
176 pounds ÷ 2.2 = 80 kg (approximately)
Step 2: Calculate the maximum safe dosage for the client. We know that the maximum safe dosage of valproic acid is 60 mg/kg/day. So, we have:
60 mg/kg/day × 80 kg = 4800 mg/day
So, the maximum safe dosage for a client who weighs 176 pounds is 4800 mg/day.
Choice C rationale:
3520 mg/day is not the correct answer. It does not accurately calculate the maximum safe dosage based on the client's weight.
Choice D rationale:
6171 mg/day is not the correct answer. It is significantly higher than the correct calculation and would exceed the maximum safe dosage for the client's weight.

Correct Answer is B
Explanation
Choice A rationale:
Drinking electrolyte fluid replacements may be necessary if the client is dehydrated due to diabetic ketoacidosis (DKA). However, addressing the increased thirst, which is a sign of DKA, should involve insulin administration to correct the underlying problem of high blood sugar.
Choice B rationale:
Giving a dose of regular insulin as prescribed is the most appropriate action to address increased thirst in a client with type 1 diabetes and early signs of DKA. Elevated blood sugar levels are the cause of the increased thirst, and insulin helps lower blood sugar levels.
Choice C rationale:
Resuming normal physical activity may not be advisable when a client is experiencing early signs of DKA. Strenuous physical activity can exacerbate hyperglycemia, and the primary focus should be on insulin administration and rehydration.
Choice D rationale:
Measuring urine output over the next 24 hours is important for monitoring hydration status in a client with DKA. However, the immediate priority is to address the increased thirst and hyperglycemia with insulin therapy.
Correct Answer is D
Explanation
Choice A rationale:
Assigning the newly hired unlicensed assistive personnel (UAP) to clients who require the least complex level of care is not the best approach to ensure adequate care for all clients. It may limit the UAP's opportunities for learning and growth and may not fully utilize their skills.
Choice B rationale:
Asking the most experienced UAP to partner with the newly hired UAP is a reasonable approach, but it may not provide a comprehensive solution. It can be beneficial for mentorship and guidance, but it may not address all the clients' needs efficiently.
Choice C rationale:
Reviewing the UAP's skills checklist and experience with the person who hired the UAP is an important step in assessing competency. However, it alone may not ensure adequate care for all clients. Competency assessment should be ongoing and include direct observation of care delivery.
