A patient has been experiencing acute diarrhea. In order to control this condition, the healthcare provider initially orders Lomotil 10 ml (2 teaspoons), four times a day. Every 5 mL (1 teaspoon) contains 2.5 mg of medication. How many milligrams of medication will the patient receive a day?
15 mg
20 mg
10 mg
2.5 mg
The Correct Answer is B
A. 15 mg: This calculation is incorrect because it underestimates the total daily dosage.
B. 20 mg: This calculation is correct. Here’s the breakdown: Each dose is 10 mL (which contains 5 mg), given four times a day. Thus, 5 mg per dose × 4 doses = 20 mg daily.
C. 10 mg: This calculation is incorrect as it only accounts for two doses rather than four daily doses.
D. 2.5 mg: This calculation is incorrect because it represents the dosage per 5 mL (1 teaspoon), not the total daily dosage.

Correct Answer is B
Explanation
A. Inhale rapidly when using the spacer with the MDI. Inhalation should be slow and deep to allow the medication to be delivered effectively to the lungs. Rapid inhalation can cause the medication to be deposited in the oropharynx instead.
B. The spacer increases the amount of medication delivered to the lungs. A spacer helps to improve medication delivery to the lungs by allowing more time for the medication to be inhaled and reducing deposition in the mouth and throat.
C. The spacer increases the amount of medication delivered to the oropharynx. The spacer actually reduces the amount of medication delivered to the oropharynx by holding the medication in a chamber, allowing for more medication to reach the lungs.
D. Cover exhalation slots of the spacer with lips when inhaling. The exhalation slots should remain open to allow for normal breathing. The child should create a good seal around the mouthpiece but not block any slots.
