A patient has been prescribed 1 L of Lactated Ringer’s IV to be infused over a 12-hour period.

The IV administration set delivers 15 gtt/mL. What should be the infusion rate in gtt/min? (Provide a numerical value only.

If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["21"]

Step 1 is: Convert 12 hours into minutes. 12 hours × 60 minutes/hour = 720 minutes.

Step 2 is: Calculate the infusion rate. (1000 mL ÷ 720 minutes) × 15 gtt/mL = 20.83 gtt/min. Therefore, the infusion rate should be approximately 21 gtt/min when rounded to the nearest whole number.

Correct Answer is ["1.32"]

Explanation

Step 1 is to convert the patient’s weight from pounds to kilograms. There are approximately 2.2046 pounds in 1 kilogram. So, the patient’s weight in kilograms is 132 lb ÷ 2.2046 = 59.87 kg.

Step 2 is to calculate the total dose of lorazepam the patient should receive. The prescribed dose is 44 mcg/kg. So, the total dose in micrograms is 44 mcg/kg × 59.87 kg = 2634.28 mcg.

Step 3 is to convert the total dose from micrograms to milligrams. There are 1000 micrograms in 1 milligram. So, the total dose in milligrams is 2634.28 mcg ÷ 1000 = 2.63428 mg.

Step 4 is to calculate the volume of lorazepam solution to administer. The concentration of the solution is 2 mg/mL. So, the volume in milliliters is 2.63428 mg ÷ 2 mg/mL = 1.31714 mL. Therefore, the nurse should administer approximately 1.32 mL of the lorazepam solution, rounding to the nearest hundredth as required.

A. diagnosed at the age of 4 years old and has had 2 previous hospitalizations B. reports taking edible marijuana C. started having difficulty breathing on a hike D. took her usual dose of albuterol, but the symptoms did not resolve E. mild subcostal retractions F. Wheezes are noted throughout the lung fields G. client is pale H. heart rate is 122 beats/minute I. blood pressure 134/85 mm Hg J. oxygen saturation 91% on room air

Correct Answer is ["C","D","E","F","G","H","J"]

Explanation

Based on the provided information, the following assessment findings require immediate follow-up by the nurse:

Difficulty breathing on a hike: This is a significant symptom of asthma exacerbation and needs immediate attention.
Symptoms did not resolve after taking albuterol: Albuterol is a quick-relief medication for asthma symptoms. If symptoms do not improve after its use, it indicates that the asthma exacerbation is severe.
Mild subcostal retractions: This is a sign of respiratory distress and indicates that the client is using accessory muscles to breathe.
Wheezes noted throughout the lung fields: Wheezing is a common sign of asthma and indicates airway obstruction.
The client is pale: Paleness can be a sign of decreased oxygenation.
Heart rate of 122 beats/minute: A high heart rate can be a sign of distress or could be due to the body’s attempt to compensate for decreased oxygenation.
Oxygen saturation of 91% on room air: Normal oxygen saturation is typically 95% or higher. A saturation of 91% indicates that the client is not getting enough oxygen.
