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.

Correct Answer is D
Explanation
The priority topic for the nurse to review with the client is monitoring changes in weight.
A sudden weight gain may mean that the client’s heart failure is getting worse and they should call their doctor if they have a sudden weight gain, such as more than 2 to 3 pounds in a day or 5 pounds in a week.
Choice A is wrong because while daily exercise is important for overall health, it is not the priority topic for the nurse to review with the client.
Choice B is wrong because while daily sodium restrictions are important for managing heart failure, it is not the priority topic for the nurse to review with the client.
Choice C is wrong because while monitoring fluid intake is important for managing heart failure, it is not the priority topic for the nurse to review with the client.
Correct Answer is B
Explanation
This statement indicates an understanding of the teaching because serum ammonia levels can be elevated in liver disease and are used to monitor the progression of liver disease.
Choice A is incorrect because glucose levels are not typically used to monitor liver disease.
