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.

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 D

Explanation

The client’s ABG results show a pH of 7.24, which is below the normal range of 7.35-7.45 and indicates acidosis.
The PaCO2 is within the normal range of 35-45 mm Hg, indicating that the acidosis is not caused by a respiratory issue.
The HCO3 level is 18 mEq/L, which is below the normal range of 22-28 mEq/L and indicates a primary metabolic cause for acidosis.
Respiratory acidosis is not indicated by the ABG results as the PaCO2 is within the normal range.
B) Metabolic alkalosis is not indicated by the ABG results as the pH and HCO3 levels are below their respective normal ranges.
C) Respiratory alkalosis is not indicated by the ABG results as the pH is below the normal range and the PaCO2 is within the normal range.

A. Pallor. B. Increased appetite. C. Bone loss. D. Hypoglycemia.

Correct Answer is C

Explanation

Leuprolide can cause bone loss, which can lead to osteoporosis and an increased risk of bone fractures.
Choice A, Pallor, is not the correct answer because pallor (pale skin) is not a common side effect of leuprolide.
Choice B, Increased appetite, is not the correct answer because increased appetite is not a common side effect of leuprolide.
Choice D, Hypoglycemia, is not the correct answer because hypoglycemia (low blood sugar) is not a common side effect of leuprolide.
