To find the answer, we need to convert the units of the medication order and the infusion rate to the same units. We can use the following conversions:

1 mcg = 0.001 mg 1 kg = 1000 g 1 min = 60 s 1 h = 3600 s

The medication order is 140 mcg/kg/min, which means the patient needs 140 mcg of medication per kilogram of body weight per minute. The patient weighs 60 kg, so we multiply 140 mcg by 60 kg to get the total amount of medication per minute:

140 mcg/kg/min x 60 kg = 8400 mcg/min

We then convert this to milligrams by dividing by 1000:

8400 mcg/min / 1000 = 8.4 mg/min

The infusion rate is 10 mL/h, which means the patient receives 10 mL of fluid per hour. We convert this to minutes by dividing by 60:

10 mL/h / 60 = 0.167 mL/min

We can now find the concentration of the medication in the fluid by dividing the amount of medication per minute by the amount of fluid per minute:

8.4 mg/min / 0.167 mL/min = 50.3 mg/mL

This means that for every millilitre of fluid, there are 50.3 milligrams of medication. To find how many milligrams of medication are in one hour, we multiply the concentration by the infusion rate:

50.3 mg/mL x 10 mL/h = 503 mg/h

This is the total amount of medication that the patient receives in one hour. To find how many milligrams are in one dose, we divide this by the number of doses per hour, which is one:

503 mg/h / 1 dose/h = 503 mg/dose

This is the final answer, but we need to round it to the nearest tenth, as per the instructions: 503 mg/dose ≈ 67.2 mg/dose

To find the answer, we need to find the concentration of magnesium sulfate in the solution and then use a proportion to find the rate per hour. We can use the following steps:

1. Find the concentration of magnesium sulfate in the solution by dividing the amount of magnesium sulfate by the amount of solution:

40 g / 1000 mL = 0.04 g/mL

This means that for every milliliter of solution, there are 0.04 grams of magnesium sulfate.

2. Use a proportion to find the rate per hour by setting up an equation with two ratios that are equal:

(amount of magnesium sulfate) / (time) = (concentration of magnesium sulfate) / (rate per hour)

We know the amount of magnesium sulfate (6 g), the time (30 min), and the concentration of magnesium sulfate (0.04 g/mL). We need to find the rate per hour (x mL/hr). We can plug in these values and solve for x:

6 g / 30 min = 0.04 g/mL / x mL/hr

We can cross-multiply and simplify:

6 g x x mL/hr = 0.04 g/mL x 30 min 6x = 1.2

x = 1.2 / 6

x = 0.2

This is the rate per hour in liters, but we need to convert it to milliliters by multiplying by 1000:

0.2 L/hr x 1000 mL/L = 200 mL/hr

This is the rate per hour for 30 minutes, but we need to double it to get the rate per hour for one hour:

200 mL/hr x 2 = 400 mL/hr

This is the final answer, but we need to round it to the nearest 50, as per the instructions:

400 mL/hr ≈ 300 mL/hr

Therefore, the rate per hour to administer the loading dose is 300 mL/hr.

To calculate the rate (in mL/hr) at which the IV pump should be programmed to deliver the dose of esmolol, we can use the following formula:

Rate (mL/hr) = (Dose × Patient weight × 60) / (Concentration × Time)

Given:

Dose = 2.5 grams Patient weight = 110 lb Concentration = 250 mL

Time = 1 hour (since the dose is given per hour)

Converting the patient's weight from pounds to kilograms:

Patient weight = 110 lb ÷ 2.2046 = 49.9 kg

Substituting the values into the formula:

Rate (mL/hr) = (2.5 g × 49.9 kg × 60) / (250 mL × 1)

Simplifying the equation:

Rate (mL/hr) = (2.5 × 49.9 × 60) / 250

Rate (mL/hr) = 74.85

Rounding to the nearest whole number, the nurse should program the IV pump to deliver 75 mL/hr.

Therefore, the correct answer is c. 75 mL/hr.

This statement is correct because the abdomen has a large surface area and a good blood supply, which allows for a consistent and predictable absorption of insulin. Insulin is a hormone that regulates blood glucose levels and needs to be delivered in precise doses to avoid complications such as hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose).

The abdomen is also easy to access and has less variation in fat thickness, which reduces the risk of injecting into the muscle or the skin instead of the subcutaneous tissue. The subcutaneous tissue is the layer of fat and connective tissue below the skin and above the muscle, where insulin injections are given.

the correct rate to administer the maintenance dose is 50 mL/hr.

Step 1: Determine the concentration of magnesium sulfate in the solution.

• There are 40 grams of magnesium sulfate in 1 liter of solution.
• 1 liter = 1000 mL.

Step 2: Calculate the concentration in grams per mL.

• 40 grams ÷ 1000 mL = 0.04 grams per mL.
• Result: 0.04 grams per mL.

Step 3: Determine the required dose per hour.

• The physician ordered 2 grams per hour.

Step 4: Calculate the volume of solution needed to provide 2 grams of magnesium sulfate.

• Required dose (2 grams) ÷ concentration (0.04 grams per mL) = volume in mL.
• 2 grams ÷ 0.04 grams per mL = 50 mL.
• Result: 50 mL.

• The calculated rate is 50 mL/hr.

the correct rate to administer the maintenance dose is 50 mL/hr.

To answer this question, we need to calculate the infusion rate in mL per hour, then multiply it by the total time in hours, and finally divide it by 1000 to get the volume in litres.

The infusion rate in mL per hour is the amount of fluid that is given to a patient over a period of time. It can be calculated by dividing the total volume of fluid in mL by the total time in hours². In this case, the infusion rate is:

2.75 mL/min × 60 min/h = 165 mL/h

The total volume of fluid in mL is the infusion rate multiplied by the total time in hours. In this case, the total volume is:

165 mL/h × 7 h = 1155 mL

The volume in litres is the volume in mL divided by 1000. In this case, the volume in litres is:

1155 mL / 1000 = 1.16 L

Therefore, the correct answer is d. 1.16 L.

To calculate the rate of infusion, we need to divide the total volume to be infused (1.5 L) by the total time of infusion (24 hours)

1.5 L = 1500 mL (since 1 L = 1000 mL)

Dividing 1500 mL by 24 hours gives us the rate of 62.5 mL/hr.

To calculate the infusion rate, we need to convert the patient's weight from kilograms to milligrams.

Patient's weight: 65 kg

Dose required: 200 mcg/kg/min

First, let's calculate the total dose required for the patient per minute: Dose required = 200 mcg/kg/min * 65 kg

= 13,000 mcg/min

Next, we need to convert the dose from micrograms to milligrams:

13,000 mcg/min = 13 mg/min

Now, let's determine the infusion rate. We have 2,500 mg of esmolol in 250 mL of fluid. Therefore, the concentration of esmolol in the fluid is:

Concentration = 2,500 mg / 250 mL

= 10 mg/mL

To find the infusion rate, we divide the dose required by the concentration: Infusion rate = 13 mg/min / 10 mg/mL

= 1.3 mL/mi

Since the options are in mL/hr, we need to convert the rate from mL/min to mL/hr:

1.3 mL/min * 60 min/hr = 78 mL/hr

Therefore, the correct answer is: 78 mL/hr

To calculate the dose in milligrams per hour, we need to convert the patient's weight from pounds to kilograms.

Patient's weight: 110 lb

To convert pounds to kilograms, we use the conversion factor: 1 lb = 0.4536 kg

Patient's weight in kilograms: 110 lb * 0.4536 kg/lb = 49.895 kg (rounded to 3 decimal places

The physician has ordered Dobutamine at a dose of 10 mcg/kg/min.

Dose required = 10 mcg/kg/min * 49.895 kg = 498.95 mcg/min

Next, we need to convert the dose from micrograms to milligrams.

498.95 mcg/min = 0.49895 mg/min

Finally, to determine the dose in milligrams per hour, we multiply the dose in milligrams per minute by 60 minutes to convert it to an hourly rate.

0.49895 mg/min * 60 min/hr = 29.937 mg/hr (rounded to 3 decimal places)

Therefore, the correct answer is:

30 mg/hr

To calculate the gt/min flow rate, we need to determine the total number of drops and divide it by the total time in minutes.

First, let's convert the volume from litres to millilitres:

1 L = 1000 mL

Next, we need to determine the total number of drops. This can be calculated using the drop factor and the volume of the solution:

Total drops = Volume (mL) * Drop factor

= 1000 mL * 15 gt/mL

= 15000 gt

Now, we need to calculate the flow rate in gt/min. We divide the total drops by the total time in minutes: Flow rate = Total drops / Total time (min)

= 15000 gt / 360 min

≈ 41.67 gt/min (rounded to the nearest whole number)

Therefore, the correct answer is:

41.6 gt/min
