A nurse is preparing to administer amoxicillin 320 mg PO every 12 hours to an infant. The amount available is amoxicillin suspension 400 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4.0"]
Step 1: Determine the dosage required. 320 mg
Step 2: Determine the concentration of the suspension. 400 mg per 5 mL
Step 3: Calculate the volume needed. 320 mg ÷ 400 mg per 5 mL = 320 ÷ 400 × 5 = 0.8 × 5 = 4 mL
The nurse should administer 4.0 mL per dose.

Correct Answer is A
Explanation
A: Posting a “No Smoking” sign in the home is crucial for safety when using home oxygen. Oxygen can accelerate combustion, making even a small spark potentially dangerous. This sign serves as a constant reminder to avoid smoking and open flames near the oxygen source.
B: Attaching oxygen containers to a fixed object is important to prevent them from falling over and potentially causing damage or leaks. However, this is not the most critical instruction compared to ensuring no smoking around oxygen.
C: Storing spare oxygen tanks in a closet is not recommended. Oxygen tanks should be stored in a well-ventilated area to prevent the buildup of oxygen, which could increase the risk of fire.
D: Notifying the fire department that oxygen is used in the home is a good safety measure. It ensures that emergency responders are aware of the presence of oxygen, which can affect their approach in case of a fire. However, it is not as immediate a safety measure as posting a “No Smoking” sign.
E: Ensuring oxygen tubing is no longer than 60 feet in length is important to maintain adequate oxygen flow and prevent tripping hazards. However, this is a secondary safety measure compared to preventing smoking around oxygen.
