Order: Cefotaxime 750mg IM twice a day.

Available: 1gm.

The pamphlet states to add 3mL of diluent equals 3.4 mL. How many milliliters (mL) would you give per dose?

Answer and Explanation

The Correct Answer is ["220.6 "]

Here's the breakdown of the calculation: 

Calculate the concentration of the medication after adding diluent: 

Concentration = (Amount of medication) / (Total volume) 

Concentration = (1 gm) / (3.4 mL) 

Concentration = 0.294 mg/mL 

Determine the desired amount of medication per dose: 

Desired amount = 750 mg 

Calculate the volume of the prepared solution needed to deliver the desired amount of  medication: 

Volume = (Desired amount) / (Concentration) 

Volume = (750 mg) / (0.294 mg/mL)

Volume = 2551.36 mL ≈ 220.6 mL (rounded to one decimal place) 

Therefore, you would need to administer approximately 220.6 mL of the prepared solution per  dose to deliver 750mg of cefotaxime.

Correct Answer is B

Explanation

Choice A rationale
Giving an infant with a positive PKU test a high protein diet is not recommended. This is because phenylalanine, which cannot be broken down by individuals with PKU, is found in high-protein foods.
Choice B rationale
Parents of infants with a positive PKU test should provide the infant with a diet containing small amounts of phenylalanine. This is because while phenylalanine is harmful in large amounts to individuals with PKU, it is still an essential amino acid that the body needs in small amounts.
Choice C rationale
Early introduction of cow’s milk is not necessary before 1 year of age for infants with a positive PKU test. In fact, cow’s milk is high in phenylalanine and should be avoided.
Choice D rationale
Following up with a pediatric cardiologist is not specifically related to the dietary management of PKU. While regular medical supervision is important for children with PKU, it does not necessarily have to be with a cardiologist.
