To calculate the rate at which the nurse should set the IV pump to deliver the LR infusion, we need to divide the total volume (500 ml) by the total time (2 hours).

500 ml / 2 hours = 250 ml/hr

Therefore, the nurse should set the IV pump to deliver the LR infusion at a rate of b. 250 mL/hr.

Subcutaneous (SC) insulin is usually administered into the abdomen as the preferred site because there is steady absorption of insulin from this area.

The abdomen has a rich blood supply and a relatively higher number of capillaries compared to other subcutaneous sites. As a result, insulin injected into the abdominal subcutaneous tissue is absorbed more consistently and predictably. This allows for better control of blood glucose levels.

To calculate the rate of infusion required for the continuous intravenous (IV) infusion of 1.5 L of normal saline (NS) over 24 hours, we need to divide the total volume (1500 ml) by the total time (24 hours).

1500 ml / 24 hours = 62.5 ml/hr

Therefore, the rate of infusion that should be set in the infusion pump is a. 62.5 mL/hr.

B. 41.7 mL/hr: This rate is too low and would result in the infusion taking longer than the prescribed 24 hours.

C. 20.8 mL/hr: This rate is even lower and would result in an even longer infusion time, which is not consistent with the prescribed 24 hours.

D. 83.3 mL/hr: This rate is too high and would result in the infusion being delivered faster than the prescribed 24 hours.

Therefore, the correct rate of infusion to be set in the infusion pump for the continuous IV infusion of 1.5 L of normal saline over 24 hours is a. 62.5 mL/hr, as it ensures the prescribed volume is infused within the specified time frame.

To calculate the total volume of IV fluid being infused, we need to multiply the infusion rate ratio (2.75 mL/min) by the total time (7 hours) and then convert the result to liters.

2.75 mL/min * 60 min/hour * 7 hours = 1155 mL

To convert mL to liters, we divide by 1000:

1155 mL / 1000 = 1.155 L

Therefore, the total volume of IV fluid being infused is d. 1.155 L.

A. 1.161 L: This value is slightly higher and does not match the calculated result.

B. 1.25 L: This value is significantly higher and does not match the calculated result.

C. 1.15 L: This value is slightly lower and does not match the calculated result.

Therefore, the correct total volume of IV fluid being infused is d. 1.155 L, as calculated based on the given infusion rate ratio and total time.

To calculate the mL/hr flow rate for the continuous infusion of 0.9% sodium chloride solution over 15 hours, we need to divide the total volume (2.5 L) by the total time (15 hours) and then convert the result to mL/hr.

2.5 L / 15 hours = 166.67 mL/hr

Therefore, the mL/hr flow rate for continuous infusion is a. 166.67 mL/hr.

To calculate the rate at which the nurse should infuse esmolol to the client, we need to determine the total amount of medication (in mg) required per minute and then convert it to mL/hr based on the concentration of the medication.

First, we need to calculate the total amount of esmolol required per minute:

Dose per minute = dose/kg/min x weight Dose per minute = 200 mcg/kg/min x 65 kg

To convert mcg to mg, divide by 1000:

Dose per minute = (200 mcg/kg/min x 65 kg) / 1000

Now, let's calculate the rate of infusion based on the concentration of the medication:

Rate of infusion (mL/hr) = (Dose per minute (mg/min) / Concentration (mg/mL)) x 60 min/hr

Given that the dose on hand is 2,500 mg esmolol in 250 mL of fluid:

Rate of infusion (mL/hr) = ((200 mcg/kg/min x 65 kg) / 1000 mg/mg) / (250 mL/2500 mg) x 60 min/hr

Simplifying the equation:

Rate of infusion (mL/hr) = (13 mg/min) / (1 mL/min) x 60 min/hr

Rate of infusion (mL/hr) = 13 mL/hr

Therefore, the rate at which the nurse should calculate to infuse esmolol is b. 13 mL/hr, rounded to the nearest whole number.

To calculate the dosage of Dobutamine in milligrams per hour (mg/hr), we need to convert the patient's

weight from pounds to kilograms and then multiply it by the ordered dose.

First, let's convert the patient's weight from pounds to kilograms:

110 lb / 2.2046 = 49.9 kg (rounded to the nearest tenth)

Now, we can calculate the dosage in milligrams per hour: Dosage = dose per kg/min x weight in kg x 60 min/hr Dosage = 10 mcg/kg/min x 49.9 kg x 60 min/hr

To convert mcg to mg, divide by 1000:

Dosage = (10 mcg/kg/min x 49.9 kg x 60 min/hr) / 1000

Calculating the dosage:

Dosage = 29.94 mg/hr (rounded to the nearest hundredth)

Therefore, the patient should receive approximately 30 mg/hr of Dobutamine, which corresponds to the option.

To calculate the gt/min flow rate for administering 1 L of 0.9% sodium chloride solution over 6 hours, we need to determine the total number of drops required and then divide it by the total time in minutes.

First, let's calculate the total volume of the solution in mL:

1 L = 1000 mL

Next, we need to calculate the total number of drops based on the drop factor:

Total drops = total volume (mL) x drop factor (gt/mL) Total drops = 1000 mL x 15 gt/mL

Now, let's calculate the flow rate in gt/min:

Flow rate (gt/min) = total drops / total time (min)

Flow rate (gt/min) = (1000 mL x 15 gt/mL) / (6 hours x 60 min/hour)

Simplifying the equation:

Flow rate (gt/min) = (15000 gt) / (360 min)

Calculating the flow rate:

Flow rate (gt/min) = 41.67 gt/min (rounded to the nearest hundredth)

Therefore, the gt/min flow rate for administering 1 L of 0.9% sodium chloride solution over 6 hours is approximately 41.67 gt/min, which corresponds to option a. 41.6 gt/min.

To calculate the rate in mL/hr that the nurse should program into the IV pump for administering nitroprusside to the patient, we need to convert the patient's weight from pounds to kilograms and then calculate the dosage based on the weight and ordered dose.

First, let's convert the patient's weight from pounds to kilograms: 154 lb / 2.2046 = 69.85 kg (rounded to the nearest hundredth)

Now, we can calculate the dosage in mcg/min:

Dosage = dose per kg/min x weight in kg Dosage = 3 mcg/kg/min x 69.85 kg

To convert mcg to mg, divide by 1000:

Dosage = (3 mcg/kg/min x 69.85 kg) / 1000

Now, let's calculate the rate in mL/hr:

Rate (mL/hr) = (Dosage (mg/min) / Concentration (mg/mL)) x 60 min/hr

Rate (mL/hr) = ((3 mcg/kg/min x 69.85 kg) / 1000) / (100 mcg/mL) x 60 min/hr

Simplifying the equation:

Rate (mL/hr) = (0.20955 mg/min) / (0.1 mL/min) x 60 min/hr

Rate (mL/hr) = 1257.3 mL/hr

Therefore, the nurse should program the IV pump to deliver nitroprusside at a rate of approximately 1257.3 mL/hr, which corresponds to option a. 1260 mL/hr.

A pediatric medication dose calculated from an adult dose should be avoided if the drug insert specifically states that the medication is not intended for pediatric use.

The drug insert or package labeling provides important information about the medication, including indications, dosage, contraindications, and safety considerations for different patient populations. If the drug insert explicitly mentions that the medication is not suitable for use in pediatric patients, it means that the medication has not been adequately studied or approved for use in children. In such cases, it is essential to follow the prescribing guidelines and seek alternative medications or dosage forms that are specifically approved for pediatric use.
