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.)

Answer and Explanation

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 D

Explanation

A) "I can store unopened bottles of insulin in the freezer."

This statement is incorrect. Insulin should not be stored in the freezer. Insulin should be stored in the refrigerator, and the currently used vial can be kept at room temperature for up to 28 days to avoid the discomfort of injecting cold insulin.

B) "I should not take my regular insulin when I am sick."

This statement is incorrect. When a person with type 1 diabetes is sick, it's important to continue taking insulin. In fact, during illness, blood sugar levels can become more difficult to manage, and insulin may be needed in adjusted doses. Skipping insulin during sickness can lead to uncontrolled blood sugar levels and potentially worsen the illness.

C) "My morning blood glucose should be between 90 and 130."

This statement is a good range to aim for in terms of fasting blood glucose levels, but it's not an indication of understanding the teaching about diabetes management as a whole. While this knowledge is important, the statement about eating a snack before playing soccer directly reflects understanding of how to manage blood sugar during physical activity.

"D) I should eat a snack half an hour before playing soccer."

Explanation:

Managing blood sugar levels is crucial for individuals with type 1 diabetes, especially when engaging in physical activities like playing soccer. Eating a snack before playing helps prevent hypoglycemia (low blood sugar) during exercise. Physical activity can cause the body to use up glucose faster, potentially leading to low blood sugar levels, and having a snack before exercise can help maintain stable blood sugar levels.

A. "My son might complain of feeling shaky when he has a low blood glucose level B. "My son might have nausea and vomiting with hypoglycemia C. Sweating can occur with hyperglycemia D. The onset of low blood glucose usually occurs slowly

Correct Answer is A

Explanation

A. "My son might complain of feeling shaky when he has a low blood glucose level."

Explanation: Correct Choice. Shaking or feeling shaky is a common symptom of low blood glucose levels, also known as hypoglycemia. When blood sugar drops too low, the body releases adrenaline, causing shaking or trembling. This response is indicative of an understanding of hypoglycemia symptoms.

B. "My son might have nausea and vomiting with hypoglycemia."

Explanation: Nausea and vomiting are not typical symptoms of hypoglycemia (low blood sugar). They are more commonly associated with hyperglycemia (high blood sugar) or other conditions. This statement is not accurate in the context of hypoglycemia.

C. "Sweating can occur with hyperglycemia."

Explanation: Sweating is more commonly associated with hypoglycemia (low blood sugar) rather than hyperglycemia (high blood sugar). When blood sugar levels drop too low, the body can respond with sweating as part of the adrenaline release. Sweating is not a typical symptom of hyperglycemia.

D. "The onset of low blood glucose usually occurs slowly."

Explanation: The onset of low blood glucose (hypoglycemia) can vary. It can occur suddenly, especially if the individual takes too much insulin or diabetes medication, leading to a rapid drop in blood sugar. The correct understanding is that the onset of low blood glucose can be rapid and not always slow.
