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

Answer and Explanation

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 ["250"]

Explanation

DesiredDose=250mg

AvailableConcentration=125mg/5mL

VolumetoAdminister=DesiredDose/AvailableConcentration × Volume

= 250 mg ÷ 125 mg/5mL

= 250/125 × 5mL

= 2 ×5mL

= 10 mL

So, the nurse should administer 10 mL.

A. bronchi B. nasal passages C. alveoli D. larynx

Correct Answer is C

Explanation

A. bronchi: The bronchi are air passages that conduct air into the lungs. They branch into smaller tubes (bronchioles) but are not involved in the actual gas exchange process.
B. nasal passages: The nasal passages filter, warm, and humidify incoming air. They are involved in air preparation but not in the exchange of gases.
C. alveoli: The alveoli are tiny sacs within the lungs where oxygen and carbon dioxide are exchanged between the air and blood. This is the primary site for gas exchange in the respiratory system.
D. larynx: The larynx, or voice box, is involved in sound production and protecting the airway during swallowing. It is not involved in gas exchange.
