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. Always infantize the child
Incorrect Explanation: "Infantizing" a child with a growth hormone deficiency is not a relevant or appropriate approach.
Explanation: Growth hormone deficiency is a medical condition that affects a child's growth. Treating the child as an infant could potentially have negative psychological and social effects. It's important to provide appropriate support and understanding without treating the child differently due to their medical condition.
B. Monitor for leukemia
Incorrect Explanation: Monitoring for leukemia is not directly related to growth hormone deficiency.
Explanation: Growth hormone deficiency primarily affects a child's growth and development due to inadequate production of growth hormone. While there might be certain health concerns associated with the condition, monitoring for leukemia is not a common aspect of managing growth hormone deficiency.
C. Help the parents set realistic goals based on the child's age and abilities
Correct Explanation: This is an important aspect to include in teaching.
Explanation: When a child is diagnosed with growth hormone deficiency, it's crucial for parents to set realistic expectations regarding their child's growth. Growth hormone therapy can help, but it's essential to understand that the child's growth might still differ from their peers. Setting realistic goals based on the child's age and abilities can help manage expectations and provide appropriate support.
D. This illness is only seen in males
Incorrect Explanation: Growth hormone deficiency is not limited to males.
Explanation: Growth hormone deficiency can affect individuals of any gender. It is not exclusive to males. The condition results from insufficient production of growth hormone by the pituitary gland, and it can occur in both males and females.
Correct Answer is D
Explanation
A. Elevated blood glucose is remarkable with Cushing's Triad:
Elevated blood glucose is not one of the components of Cushing's Triad. The triad focuses on cardiovascular and respiratory changes associated with increased intracranial pressure, not blood glucose levels.
B. Cushing's Triad includes a positive Macawen's sign:
Macawen's sign is not part of Cushing's Triad. Cushing's Triad is specifically related to the physiological responses seen in response to increased intracranial pressure and is not associated with Macawen's sign.
C. Cushing's Triad includes tachycardia, seizures and rapid respirations:
This option is not accurate. Cushing's Triad involves bradycardia (slow heart rate), irregular respirations, and a widening pulse pressure. Tachycardia (rapid heart rate) and seizures are not part of Cushing's Triad but might be indicative of other medical conditions or complications.
D. Bradycardia, irregular respirations and a widening pulse pressure.
Explanation: Cushing's Triad is a set of three clinical signs that are indicative of increased intracranial pressure (ICP) and are considered ominous as they suggest serious brain injury or pathology. The triad consists of:
Bradycardia: This refers to a slow heart rate. As intracranial pressure increases, it can lead to a decreased heart rate due to pressure on the brainstem, which is involved in regulating heart rate.
Irregular Respirations: Increased ICP can affect the brainstem's control over breathing, leading to irregular patterns of breathing, often known as Cheyne-Stokes respiration. This is characterized by periods of rapid breathing followed by apnea (temporary cessation of breathing).
Widening Pulse Pressure: Pulse pressure is the difference between systolic and diastolic blood pressure. An increase in ICP can cause an increase in systolic blood pressure and a decrease in diastolic blood pressure, leading to a widening pulse pressure.
