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)

A.

2.5 mL.

B.

25 mL.

C.

2.05 mL.

D.

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 C

Explanation

Step 1: 100 mL ÷ 30 min

Step 2: (100 mL ÷ 30 min) × 60 min/hr

Step 3: 3.33 mL/min × 60 min/hr

Answer: 200 mL/hr

Correct Answer is C

Explanation

The first step when finding an unresponsive person is to check their breathing by tilting their head back and looking and feeling for breaths.
When a person is unresponsive, their muscles relax and their tongue can block their airway so they can no longer breathe.
Tilting their head back opens the airway by pulling the tongue forward.
Palpating for the client’s carotid pulse is a way to check if the client has a pulse and is still breathing.
Choice A: Initiating cardiac monitoring for the client is not an answer because it is not mentioned as the first action to take in my sources.
Choice B: Apply a blood pressure cuff is not an answer because it is not mentioned as the first action to take in my sources.
Choice D: Establishing an IV access is not an answer because it is not mentioned as the first action to take in my sources.
