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.
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.
B. 25 mL.
None
C. 2.05 mL.
None
D. 2.25 mL.

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.

A nurse is providing teaching to a client who is receiving opioids for pain management.
Which of the following information should the nurse include in the teaching?
A. "Itching indicates you are having an allergic reaction to the medication.".
Choice A is not correct because itching can be a side effect of opioids and does not necessarily indicate an allergic reaction.
B. "Monitor urinary output for retention.".
“Monitor urinary output for retention.” Urinary retention is a common side effect of opioid use and should be monitored.
C. "Restrict fluid intake if you experience constipation.".
Choice C is not correct because restricting fluid intake can worsen constipation.
D. "Avoid taking antiemetics with the medication.".
Choice D is not correct because antiemetics may be prescribed to manage nausea and vomiting, which are common side effects of opioids.

A nurse is caring for an older adult client who is suspected of having septicemia.
Which of the following actions is the nurse's priority?
A. Obtain a WBC count with differential.
Choice A is incorrect because while a WBC count with differential can provide information about the presence of an infection, it does not identify the specific microorganism causing the infection.
B. Obtain a blood specimen for culture and sensitivity testing.
The priority action for a nurse caring for an older adult client who is suspected of having septicemia is to obtain a blood specimen for culture and sensitivity testing. This test will help identify the specific microorganism causing the infection and determine the most effective antibiotic treatment.
C. Obtain a history to determine recent injuries.
Choice C is incorrect because while obtaining a history to determine recent injuries can provide useful information, it is not the priority action.
D. Obtain a broad-spectrum antibiotic for rapid administration.
Choice D is incorrect because while administering a broad-spectrum antibiotic may be necessary, it should not be done before obtaining a blood specimen for culture and sensitivity testing.
