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
Fluid Requirement (mL/24 hours) = Weight (kg) × Fluid Requirement (mL/kg)
Given that the child weighs 70.4 pounds, we first need to convert this weight to kilograms (1 lb = 0.453592 kg):
Weight in kg = 70.4 lb × 0.453592 kg/lb ≈ 31.89 kg
Now, let's calculate the fluid requirement using the given choices:
A) 1740:
Fluid Requirement = 31.89 kg × 55 mL/kg = 1753.95 mL
B) 134056:
This number is significantly larger than any reasonable fluid requirement and is likely an error.
C) 2:
This value is far too low to represent the fluid requirements of a child.
D) 12:
This value is also too low to represent the fluid requirements of a child.
So, the correct answer is A) 1740 mL. The child's estimated daily fluid requirement would be around 1740 mL in a 24-hour period, based on a weight of 70.4 pounds.
Correct Answer is B
Explanation
A) Low-protein, low-potassium diet:
While low-protein and low-potassium diets can be appropriate for certain kidney conditions, such as chronic kidney disease, they are not typically the primary focus in the acute phase of glomerulonephritis. Protein restriction might be considered if there is significant kidney damage, and potassium levels are elevated.
B) Low-sodium fluid-restricted diet:
This is the most appropriate option. In acute glomerulonephritis, the kidneys' ability to regulate sodium and fluid balance may be impaired due to inflammation and decreased glomerular filtration. Fluid retention and peripheral edema are common. A low-sodium diet helps reduce fluid retention and manage edema.
C) Low carbohydrate, low-protein diet:
Low-carbohydrate and low-protein diets are not the main dietary considerations for acute glomerulonephritis. The primary focus is on managing sodium and fluid intake due to impaired kidney function.
D) Regular diet, no added salt:
A regular diet without added salt might exacerbate the fluid retention and edema associated with acute glomerulonephritis. Sodium intake needs to be controlled to prevent further fluid buildup.
