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.

Explanation
Choice A rationale:
This statement is incorrect. Suicidal ideation is not a diagnosis in itself but rather a symptom or thought process associated with various mental health conditions.

Correct Answer is D
Explanation
Choice A rationale:
An altered level of consciousness is not a typical finding in Alzheimer's disease. This condition is characterized by cognitive decline and memory impairment, but consciousness itself is not directly affected.
Choice B rationale:
Rapid mood swings can occur in individuals with Alzheimer's disease due to the changes in brain structure and function. These mood swings are a common behavioral symptom. However, the more distinctive hallmark of Alzheimer's disease is the cognitive decline rather than mood swings.
Choice C rationale:
Excessive motor activity is not a prominent feature of Alzheimer's disease. Instead, individuals with Alzheimer's disease often experience a decline in motor skills and coordination as the disease progresses.
Choice D rationale:
Failure to recognize familiar objects is a common symptom of Alzheimer's disease. This is referred to as agnosia, where individuals may struggle to recognize familiar people, objects, or places. It results from the progressive damage to brain regions responsible for memory and sensory processing.
