A nurse is preparing to administer amoxicillin 300 mg PO. The amount lable is amoxicillin oral solution 250 mg/5 mL. How many mL should the nurse administer? (Hound the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A.

10 mL

B.

6 mL

C.

5 ml

D.

7 mL

Answer and Explanation

The Correct Answer is B

Given:

Ordered dose of amoxicillin: 300 mg

Concentration of amoxicillin oral solution: 250 mg/5 mL

 

Step 1: Set up the proportion:

Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

 

Step 2: Substitute the values:

300 mg / Volume = 250 mg/5 mL

 

Step 3: Solve for the unknown volume:

Volume = 300 mg / (250 mg/5 mL)

Volume = 300 mg x (5 mL / 250 mg)

Volume = 6 mL

Correct Answer is B

Explanation

A) Esophagus
Enteric-coated tablets are designed to not dissolve or disintegrate in the esophagus. They are coated with a protective layer that prevents the tablet from breaking down in the acidic environment of the stomach. This is to ensure that the medication is released in the part of the digestive tract where it is most needed, typically beyond the stomach.

B) Duodenum
Enteric-coated tablets are designed to disintegrate in the duodenum, which is the first part of the small intestine. The coating protects the tablet from stomach acid, allowing it to pass intact through the stomach and into the small intestine, where the pH is higher and the coating dissolves, releasing the medication for absorption.

C) Stomach
Enteric-coated tablets are specifically designed not to disintegrate in the stomach because the stomach's acidic environment could either damage the drug or cause premature release. The coating ensures that the drug is protected until it reaches the more neutral pH of the duodenum.

D) Colon
The colon is too far along in the digestive tract for enteric-coated tablets to typically disintegrate. The design of enteric coatings is intended to protect the drug until it reaches the duodenum, where absorption is most efficient. Enteric coatings are not meant to disintegrate in the colon.

Correct Answer is D

Explanation

Given:

Ordered dose of clindamycin palmitate: 225 mg

Concentration of clindamycin palmitate oral suspension: 75 mg/5 mL

Step 1: Set up the proportion:

Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

Step 2: Substitute the values:

225 mg / Volume = 75 mg/5 mL

Step 3: Solve for the unknown volume:

Volume = 225 mg / (75 mg/5 mL)

Volume = 225 mg x (5 mL / 75 mg)

Volume = 15 mL
