A nurse is caring for a client who is to receive liquid medications via a gastrostomy tube. The client is prescribed phenytoin 250 mg. The amount available is phenytoin oral solution 25 mg/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["50"]
To calculate the mL of phenytoin oral solution needed for a 250 mg dose, we can use the following equation:
Dose (mg) = Volume (mL) × Concentration (mg/mL)
Given:
Dose = 250 mg
Concentration = 25 mg/5 mL
We need to find the volume (mL):
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Volume (mL) = 250 mg / (25 mg/5 mL)
Volume (mL) = 250 mg / (5 mg/mL)
Volume (mL) = 50 mL
So, the nurse should administer 50 mL of phenytoin oral solution per dose.

Correct Answer is D
Explanation
a. Allow for adjustment of rules to correlate with the child's behavior: While flexibility can be important, allowing rules to be adjusted based on behavior can lead to inconsistency and confusion for the child. Consistent rules and expectations are crucial for children with ASD, as they thrive on predictability and structure.
b. Allow for imaginative play with peers without supervision: Children with ASD may have difficulties with social interactions and imaginative play. Supervision is important to ensure that play is safe, appropriate, and supportive of social skill development. Unsupervised play might not be beneficial if it leads to misunderstandings or conflicts.
c. Provide a flexible schedule that adjusts to the child's interests: Children with ASD generally benefit from a structured and predictable schedule rather than a flexible one that changes based on their interests. Predictability helps them feel secure and reduces anxiety. A flexible schedule could lead to increased stress and difficulty in transitioning between activities.
d. Establish a reward system for positive behavior: A reward system is an effective strategy for encouraging positive behavior in children with ASD. Reinforcement of desired behaviors helps to build and maintain new skills and can provide motivation. This approach aligns well with behavioral interventions commonly used with children on the autism spectrum.
Correct Answer is B
Explanation
A. Dizziness is always a sign of a concussion.
This statement is incorrect. While dizziness can be a symptom of a concussion, it is not always indicative of a concussion. There can be various causes of dizziness, and it is essential to consider other symptoms as well when assessing for a concussion.
B. Bike Helmet Safety
Explanation:
The correct answer to include as part of concussion/head injury prevention teaching to children and parents is "Bike helmet safety." This is because wearing a helmet while riding a bike or participating in other activities that involve head injury risks is crucial to prevent head injuries and concussions. Helmets provide protection to the head by absorbing impact energy and reducing the risk of skull fractures or traumatic brain injuries.
C. Normal fluid intake.
While staying hydrated is important for overall health, it is not directly related to concussion or head injury prevention teaching. This choice is unrelated to the topic.
D. Signs of autism.
Signs of autism are unrelated to concussion or head injury prevention teaching. This choice is not relevant to the topic at hand.
