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

The nurse should plan to insert a large-bore nasogastric tube for a client who has upper gastrointestinal bleeding due to a peptic ulcer.

Choice A is wrong because a 22-gauge IV line may be too small for rapid fluid resuscitation.
Choice B is wrong because ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of gastrointestinal bleeding.
Choice C is wrong because nitroprusside is a vasodilator used to treat hypertensive emergencies and is not typically used for upper gastrointestinal bleeding.

Choice B: “Lie down for 30 minutes after each meal” is not an answer because it is not mentioned as a self-management strategy for GERD in my sources.
