The physician orders Cimetidine HCI 300 ng PO gid. After looking at the label you have on hand, how many teaspoons will you administer to the patient?
The Correct Answer is ["1"]
Label: Cimetidine Chloride 300 mg/5 mL
To calculate the dose in teaspoons:
Determine how many mL contain the ordered dose:
300 mg is the ordered dose. The label shows that 300 mg is in 5 mL.
Therefore, 300 mg = 5 mL.
Convert mL to teaspoons:
1 teaspoon = 5 mL.
Therefore, 5 mL = 1 teaspoon.
So, 1 teaspoon is required to administer the ordered dose of 300 mg.

Explanation
What is the safe and single dose for this child?
The recommended daily dosage is 75 mg/kg/day. For a 20 kg child:
Safedailydose= 75 mg/kg/day × 20 kg
= 1500 mg/day
Since the child is receiving the medication every 8 hours, the single dose would be:
Singledose = 1500 mg ÷ 3
Correct Answer is B
Explanation
a) Interstitial fluid: Interstitial fluid is the fluid that surrounds cells, not the fluid within the cells themselves.
b) Intracellular fluid (ICF): Intracellular fluid makes up about 70% of total body water and is found inside the cells. This is the fluid that plays a key role in cellular functions.
c) Intravascular fluid: Intravascular fluid refers to the fluid within the blood vessels (plasma), which makes up about 5% of total body water.
d) Extracellular fluid (ECF): Extracellular fluid includes both interstitial fluid and intravascular fluid, but it is not the fluid within the cells.
