A nurse is preparing to administer naloxone 10 mcg/kg via IV bolus to a client who weighs 220 lb. The amount available is 0.4 mg/mL. How many mL should the nurse administer? (round off to the nearest tenth)

2.5 mL.

25 mL.

2.05 mL.

2.25 mL.

Answer and Explanation

The Correct Answer is A

Let’s break down the problem step by step:

Step 1: Convert the client’s weight from pounds (lb) to kilograms (kg). We know that 1 kg = 2.2 lbs. So, we have: 220 lb ÷ 2.2 = 100 kg

Step 2: Calculate the total amount of naloxone needed. The doctor ordered 10 mcg/kg, and the client weighs 100 kg. So, we have: 10 mcg/kg × 100 kg = 1000 mcg

Step 3: Convert micrograms (mcg) to milligrams (mg). We know that 1 mg = 1000 mcg. So, we have: 1000 mcg ÷ 1000 = 1 mg

Step 4: Calculate the volume of naloxone solution needed. The available naloxone solution is 0.4 mg/mL. So, we have: 1 mg ÷ 0.4 = 2.5 mL

So, the nurse should administer 2.5 mL of naloxone. Since we are asked to round off to the nearest tenth, the final answer remains 2.5 mL.

Correct Answer is B

Explanation

“Furosemide.” The nurse should anticipate administering furosemide because the client’s symptoms of bounding peripheral pulses, hypertension, and distended jugular veins may indicate fluid overload.
Furosemide is a diuretic medication that can help reduce fluid overload by increasing urine output.
Choice A is incorrect because diphenhydramine is an antihistamine medication that is not used to treat fluid overload.
Choice C is incorrect because acetaminophen is a pain reliever and fever reducer that is not used to treat fluid overload.
Choice D is incorrect because pantoprazole is a proton pump inhibitor that is used to treat acid reflux and stomach ulcers, not fluid overload.

A. Fasting blood glucose level. B. Glycosylated hemoglobin level. C. Oral glucose tolerance test results. D. Postprandial blood glucose level.

Correct Answer is B

Explanation

The glycosylated hemoglobin level (also known as HbA1c or A1C) is a laboratory test that reflects average levels of blood glucose over the previous two to three months.
It is the most widely used test to monitor chronic glycemic management.
Choice A is not the answer because fasting blood glucose level reflects only short-term glycemic control.
Choice C is not the answer because oral glucose tolerance test results reflect only short-term glycemic control.
Choice D is not the answer because postprandial blood glucose level reflects only short-term glycemic control.
