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 C
Explanation
A. Place a pillow under the child's head.
Explanation: While providing comfort is important, the priority in this scenario is to ensure the child's safety. Placing a pillow under the head can be considered after addressing immediate safety concerns.
B. Clear the area of hazards.
Explanation: Correct Choice. Ensuring the area is clear of hazards is the nurse's priority. During a seizure, the child can experience uncontrolled movements, and having hazards around can lead to injuries. Clearing the area helps prevent harm. But priority is to position the child side lying.
C. Position the child side-lying.
Explanation: Correct Choice. Placing the child in a side-lying position helps prevent choking and aspiration due to vomiting during the seizure. It also minimizes the risk of airway obstruction and helps manage secretions.
D. Loosen restrictive clothing.
Explanation: While loosening restrictive clothing can facilitate breathing, the priority in this situation is addressing safety concerns related to the seizure and vomiting. Ensuring a clear and safe environment takes precedence.
Correct Answer is A
Explanation
A. Inattention, Hyperactivity, Impulsivity
Explanation: Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity. These symptoms can significantly impact an individual's ability to function in various areas of their life, such as school, work, and social interactions.
The other options are not accurate descriptions of ADHD:
B. "Can never be well treated" is not correct. ADHD can be effectively managed and treated through a combination of strategies, which may include behavioral interventions, psychoeducation, counseling, and in some cases, medication.
C. "Inability to learn" is not a defining characteristic of ADHD. While individuals with ADHD might face challenges in learning due to their symptoms, they are certainly capable of learning and can benefit from tailored strategies to support their learning process.
D. "Excess tiredness, impulsivity, and hyperactivity" describes a combination of symptoms, but ADHD is specifically characterized by inattention, hyperactivity, and impulsivity. Tiredness, while not a primary symptom of ADHD, can be a secondary effect of difficulties in focusing and maintaining attention.
