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.
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.

Explanation
A pericardial friction rub is highly specific for acute pericarditis and is generally heard over the left sternal border.
It is often louder at inspiration but sometimes can be better heard on forced expiration while the patient bends forward.
Choice A is not the answer because it does not correspond to the left sternal border.
Choice B is not the answer because it does not correspond to the left sternal border.
Choice D is not the answer because it does not correspond to the left sternal border.
Correct Answer is C
Explanation
“You should expect a warm sensation after the injection of the contrast dye during the procedure.” During cardiac catheterization, a contrast dye is injected into the body to highlight blood flow through the arteries and show blockages in the blood vessels that lead to the heart.
This can cause a warm sensation.
Choice A is incorrect because usually, patients are awake during cardiac catheterization but are given medications to help them relax.
Choice B is incorrect because recovery time for a cardiac catheterization is quick.
Choice D is incorrect because there is no information found to support this statement.
