A nurse is preparing to administer amoxicillin 100 mg PO every 8 hr to a toddler who weighs 20 kg. The recommended dosage range is 20 to 25 mg/kg/day. Which of the following actions by the nurse is appropriate?
The nurse determines the prescription is above the recommended dosage range.
The nurse determines the prescription is insufficient to achieve the desired effect.
The nurse administers the prescribed dosage.
The nurse contacts the pharmacist to adjust the prescribed dosage.
The Correct Answer is B
According to the recommended dosage range of 20 to 25 mg/kg/day for a toddler weighing 20 kg, the daily dosage should be between 400 mg (20 kg x 20 mg) and 500 mg (20 kg x 25 mg).
Therefore, the prescribed dosage of 300 mg per day is below the recommended range.

Correct Answer is A
Explanation
A. Alcohol can affect blood clotting mechanisms and increase the risk of bleeding. Chronic alcohol consumption is associated with liver dysfunction, which impairs the production of clotting factors, leading to an increased risk of bleeding during and after surgery.
B. Alcohol consumption does not decrease the risk of postoperative infection. In fact, alcohol use, especially if it’s chronic, can impair the immune system and delay wound healing, potentially increasing the risk of postoperative infections.
C. Alcohol does not enhance the effectiveness of anesthesia; rather, it can complicate anesthesia management. Alcohol can interact with anesthetic agents, potentially altering their effects, leading to unpredictable outcomes.
D. Alcohol does not reduce the risk of postoperative nausea and vomiting (PONV). In fact, alcohol use can exacerbate nausea and vomiting, particularly when combined with anesthetic agents.
Correct Answer is C
Explanation
A. Petroleum-based products should not be used in conjunction with oxygen therapy. They are flammable and can pose a fire hazard when used near oxygen. Instead, use water-based moisturizers to prevent dryness of the lips and skin.
B. Wool and other synthetic fabrics can generate static electricity, which is a fire hazard when using oxygen
therapy. It’s safer to use cotton blankets, as they are less likely to cause static buildup.
C. Oxygen tanks should be stored upright to prevent them from falling over and to ensure the regulator and valves are properly aligned. Storing tanks upright helps maintain stability and prevents accidental damage to the equipment.
D. While the recommendation to keep oxygen tanks away from electrical sources is important, the distance may vary based on specific guidelines. It is generally advised to keep oxygen tanks at least 5-10 feet away from electrical sources and heat sources to avoid any risk of ignition or fire.
