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:
Assessment of tobacco use geared toward adolescents is an important topic, but it may not directly address the immediate concerns related to the increase in suicides in the community. While substance abuse can be a risk factor for mental health issues, focusing on stress self-management techniques may be more relevant in this context as it can help adolescents cope with various stressors and emotions that could contribute to suicidal thoughts.
Choice C rationale:
Showing statistics on suicide rates may be informative but may not be the most engaging and effective approach to teaching adolescents about mental health. Statistics alone may not provide them with practical tools and strategies to manage their mental well-being.
Choice D rationale:
Providing handouts for local substance abuse treatment centers is important if substance abuse is a concern, but it may not address the broader issue of mental health and suicide prevention. The primary focus should be on teaching adolescents how to manage stress and emotions in a healthy way, as this can be a preventive measure for various mental health issues, including suicidal thoughts.
Correct Answer is D
Explanation
The correct answer is choice d. Activate the lockdown procedure.
Choice A rationale:
Asking the mother if any visitors were expected to arrive is important for gathering information, but it is not the immediate priority when a newborn is missing. The primary concern is to ensure the safety and security of the infant.
Choice B rationale:
Matching ID bands of all infants and mothers on the unit is a crucial step in verifying the identity of the newborn, but it should be done after ensuring that the unit is secure and the baby cannot be taken out of the facility.
Choice C rationale:
Determining if the newborn is in the nursery is also important, but it should be done after securing the unit to prevent any potential abduction.
Choice D rationale:
Activating the lockdown procedure is the first and most critical action. This ensures that all exits are secured, preventing anyone from leaving the unit with the infant. It is a safety measure to protect the newborn and is the immediate priority in such situations.
