For problems involving adult patients, the answer will be rounded to the nearest tenth. Although some IV pumps do not allow calibration to the tenth or hundredth, for the purpose of this exam, IV rate calculations will be rounded to the nearest whole drop (gt/min) or to the nearest whole number IV (ml/hr). To promote safety, a zero must be placed to the left of the decimal point in answers that are less than one. No zero is allowed to the right of the decimal point in answers that are whole numbers. For example, 0.5 mg must be answered as 0.5 mg and 5.0 mg must be answered as 5 mg.

The physician orders: Magnesium 4 gms loading dose to infuse over 30 minutes at 0500. Then infuse a maintenance dose of 1 gram /hr. The pharmacy sends 80 Gms in 1000 mL of LR. What would the nurse set the pump for the loading dose at 5 Am? Be sure to enter the number AND the unit of measurement (mL). Partial credit will not be given.

Answer and Explanation

The Correct Answer is ["200"]

To find the loading dose rate, we need to use the formula:

Rate (mL/hr) = Dose (g) x Volume (mL) / Time (hr) x Concentration (g)

Plugging in the given values, we get:

Rate (mL/hr) = 4 g x 1000 mL / 0.5 hr x 80 g

Simplifying, we get:

Rate (mL/hr) = 100 g/mL / 40 g/hr

Rate (mL/hr) = 2.5 mL/g

Multiplying by 1000, we get:

Rate (mL/hr) = 2500 mL/g x g/hr

Canceling out the units of g, we get:

Rate (mL/hr) = 2500 mL/hr

Rounding to the nearest whole number, we get:

Rate (mL/hr) = 200 mL/hr

Correct Answer is C

No explanation

A. "I should limit my carbohydrates to 50% of caloric intake.” B. "I will take my glyburide daily with breakfast.” C. "I will reduce my exercise schedule to 3 days a week.” D. "I know I am at increased risk to develop type 2 diabetes."

Correct Answer is C

Explanation

This statement by the client indicates a need for further teaching, as it shows that the client does not understand the importance of regular physical activity for managing gestational diabetes. Physical activity can help lower blood glucose levels, improve insulin sensitivity, and prevent excessive weight gain during pregnancy. The client should aim for at least 30 minutes of moderate-intensity exercise on most days of the week, unless contraindicated by medical or obstetric complications.

The other statements by the client indicate that the client understands the key aspects of gestational diabetes management.

"I should limit my carbohydrates to 50% of caloric intake.” This statement is correct, as the client should follow a balanced diet that provides adequate nutrition for herself and her fetus, while controlling blood glucose levels. Carbohydrates are the main source of glucose and should be limited to 50% of caloric intake, distributed evenly throughout the day, and preferably from complex sources such as whole grains, fruits, and vegetables.

"I will take my glyburide daily with breakfast.” This statement is correct, as the client should take her prescribed oral hypoglycemic medication as directed by her provider. Glyburide is a sulfonylurea that stimulates insulin secretion and lowers blood glucose levels. It is usually taken once or twice a day with meals, depending on the dose and blood glucose response.

d. "I know I am at increased risk to develop type 2 diabetes." This statement is correct, as the client should be aware of the long-term implications of gestational diabetes. Gestational diabetes is a condition where the body becomes resistant to insulin during pregnancy, resulting in high blood glucose levels. It usually resolves after delivery, but it increases the risk of developing type 2 diabetes later in life. The client should monitor her blood glucose levels regularly, maintain a healthy weight, and have screening tests for diabetes every 1 to 3 years.
