The correct abbreviation twice a day is:

First, let's calculate the child's weight in kilograms:

27 lb ÷ 2.205 lb/kg = 12.25 kg

Next, we can calculate the total daily dose of albuterol that the child should receive:

0.3 mg/kg/24 hr x 12.25 kg = 3.675 mg/24 hr

We need to divide this total daily dose into three equal doses to be given every 8 hours: 3.675 mg/24 hr ÷ 3 doses = 1.225 mg/dose

The available Albuterol syrup is 2mg/5ml, which means each 5ml of syrup contains 2mg of albuterol. To administer 1.225 mg of albuterol, we need to calculate the volume of syrup required using the following formula:

Volume (ml) = (dose (mg) ÷ concentration (mg/ml))

Volume (ml) = (1.225 mg ÷ 2 mg/ml)

Volume (ml) = 0.6125 ml

Therefore, the child should receive 0.6 ml (rounded to the nearest tenth) of Albuterol syrup per dose, to be given orally three times a day.

Enteric-coated tablets and time-released tablets should never be crushed or broken before administration. Here are reasons why enteric-coated tablets and time-released tablets should never be crushed: 1. Effectiveness: Enteric-coated tablets are designed to resist the acidic environment of the stomach and dissolve in the alkaline environment of the small intestine. Crushing these tablets will alter their absorption pattern and effectiveness.

2. Safety: Time-released tablets are designed to slowly release the medication over an extended period, which helps to maintain a consistent therapeutic level in the body. Crushing these tablets can result in an immediate release of the entire dose, which can cause an overdose or adverse reactions.

3. Irritation: Crushing enteric-coated or time-released tablets can cause irritation to the throat, mouth, and airways, leading to coughing, choking, or breathing difficulties.

4. Accuracy: When tablets are crushed, the amount of medication that is delivered may be inaccurate, which can lead to underdosing or overdosing.
