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 A
Explanation
A. You do not need to lose consciousness to suffer a concussion.
This statement is true. Concussion is a type of traumatic brain injury (TBI) that can occur without loss of consciousness. Many concussions happen without the person losing consciousness at all.
B. You will suffer permanent brain damage.
This statement is not necessarily true. While some concussions can lead to lasting effects, not all cases result in permanent brain damage. The severity and long-term effects of a concussion can vary widely.
C. We encourage fluids after a concussion.
This statement is true. Adequate hydration is important after a concussion. Staying hydrated can help support the brain's recovery process.
D. Bleeding always occurs with a concussion.
This statement is not true. Concussion is defined by the disruption of normal brain function due to a blow or jolt to the head or body, and bleeding is not always a necessary component of a concussion. However, more severe head injuries could involve bleeding and would not be classified as just a concussion.
Correct Answer is D
Explanation
A) Places the infant in a side-lying position:
Positioning is important in the care of an infant with myelomeningocele. The infant is usually placed in a prone (on the abdomen) position to prevent pressure on the sac and protect the neural tissue. Placing the infant in a side-lying position may not provide the needed protection.
B) Maintains a dry dressing over the sac:
The sac should be kept moist with a sterile, non-adherent dressing moistened with saline to prevent drying and cracking, which could lead to infection.
C) Performs range of motion on the infant's hips:
Infants with myelomeningocele often have flaccid paralysis below the lesion, and excessive manipulation of the lower limbs could cause injury.
D) Takes an axillary temperature:
Rectal temperatures should never be taken, as they can cause mucosal damage or irritate the exposed spinal cord, leading to complications like meningitis. The axillary route is the safest method for temperature assessment.
