Order: 200 mL normal saline bolus IV over 15 minutes
On hand: 500 mL normal saline bags
What rate will the nurse set the pump to deliver the fluid?
The Correct Answer is ["800"]
This choice is correct because it is the result of dividing the volume of the bolus (200 mL) by the time of the infusion (15 minutes) and multiplying by 60 minutes per hour. The formula for calculating the rate of the pump is:
Rate = (Volume/Time) x 60
Therefore, the rate of the pump is:
Rate = (200 mL/ 15 min) x 60 = 800 mL/hr

Correct Answer is A
Explanation
Choice A reason: This is correct because high lipid levels, such as cholesterol and triglycerides, are a risk factor for cardiovascular disease. HMG-CoA reductase inhibitors, also known as statins, lower the production of cholesterol in the liver and reduce the risk of heart attack and stroke.
Choice B reason: This is incorrect because blood glucose of 60 is not related to the need for an HMG-CoA reductase inhibitor. Blood glucose of 60 is below the normal range and may indicate hypoglycemia, which is a low blood sugar level. Hypoglycemia can cause symptoms such as dizziness, confusion, sweating, and hunger.
Choice C reason: This is incorrect because platelets over 150,000 are not related to the need for an HMG-CoA reductase inhibitor. Platelets are blood cells that help with clotting and prevent bleeding. The normal range of platelets is 150,000 to 450,000 per microliter of blood. Platelets over 150,000 are within the normal range and do not indicate a problem.
Choice D reason: This is incorrect because low INR is not related to the need for an HMG-CoA reductase inhibitor. INR stands for international normalized ratio and is a measure of how long it takes the blood to clot. The normal range of INR is 0.8 to 1.2. Low INR means the blood clots faster than normal and may indicate a risk of thrombosis, which is a blood clot in a vein or artery.
Correct Answer is ["0.75"]
Explanation
To calculate the volume of morphine injection that the nurse should administer, we can use the following steps:
Determine the volume to be administered:
We have a concentration of 10 mg/mL.
7.5 mg ÷ 10 mg/mL = 0.75 mL
Therefore, the nurse should administer 0.75 mL of morphine injection subcutaneously.
