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 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.
Correct Answer is A
Explanation
A. Position the child laterally
Explanation: When a child is experiencing a seizure, it's important to ensure their safety and prevent injury. Positioning the child laterally, also known as the recovery position, helps keep the airway clear and allows any fluids to drain from the mouth, reducing the risk of aspiration. It also helps prevent the child from choking on saliva or vomit.
The other options are not appropriate actions during a seizure:
B. Using a padded tongue blade is not recommended during a seizure. Placing objects in the mouth during a seizure can lead to injury, including damage to the teeth, jaw, or airway.
C. Attempting to stop the seizure is not within the nurse's control. Seizures are caused by abnormal electrical activity in the brain and should not be interrupted forcefully. Instead, the focus should be on ensuring the child's safety and managing the situation until the seizure stops on its own.
D. Restraining the child's arms is not advisable during a seizure. Restraining can cause harm and increase the risk of injury to the child or others involved. It's important to allow the seizure to run its course while protecting the child from harm.
