Answer:

The correct answer is B. The mucosa is responsible for absorption and secretion.

Explanation:

The mucosa is the deepest layer of the intestinal tract, surrounding the lumen, or space inside the tube. This layer comes into direct contact with food (or bolus) and is responsible for absorption and secretion, which are important processes in digestion.

The mucosa is highly specialized in each organ of the intestinal tract, facing a low pH in the stomach, absorbing a multitude of different substances in the small intestine and also absorbing specific amounts of water in the large intestine.

14. Thomas is 3 months old and weighs 15 lb 6 oz. Thomas is prescribed a medication q6h. The label states that there's 400 mg of
lana66690 [7]

Thomas should receive 8.71 ml per day

<h3>Dosage</h3>

A dosage is the amount of a medicine or drug that someone takes or should take, and how ` they should take it.

1 oz = 0.0283495 kg; also 1 lb = 0.453592 kg.

Hence 15 lb 6 oz = (15 lb * 0.453592 kg/lb) + (6 oz * 0.0283495 kg/oz) = 6.97 kg

Since the dosage is 50 mg/kg/day. Hence amount of mg given is:

Amount of mg = 50 mg/kg/day * 6.97 kg = 348.5 mg per day

Each 10 ml contains 400 mg; hence:

ml = 348.5 mg * 10 ml per 400 mg = 8.71 ml per day

Thomas should receive 8.71 ml per day
