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
Lying down with arms at the side is not the recommended position for a breast self-exam. The recommended positions are either standing or lying down with the arm raised.
Choice B rationale
Using the finger pads of the three middle fingers to apply pressure to the breast is a correct technique for a breast self-exam. This method allows for thorough examination of the breast tissue.
Choice C rationale
It is not correct to avoid checking under the arm if the breast feels fine. The breast tissue extends into the underarm area, so it is important to check this area as well during a breast self-exam.
Choice D rationale
Working from left to right down the breast towards the ribs is not a standard instruction for a breast self-exam. The recommended method is to use a circular, up-and-down, or wedge pattern.

Correct Answer is B

Explanation

Choice A rationale
Hyperglycemia, or high blood sugar, is not typically associated with poor feeding and low temperature in infants. It’s more commonly seen in conditions like diabetes.
Choice B rationale
Neonatal infection could cause an infant to feed poorly and have a low temperature. These symptoms could be a sign of sepsis, a serious and potentially life-threatening infection that requires immediate medical attention.
Choice C rationale
Hemolytic anemia, a condition where red blood cells are destroyed faster than they can be made, is not typically associated with poor feeding and low temperature in infants.
Choice D rationale
Prematurity could potentially cause poor feeding and low temperature, but these symptoms would not typically appear suddenly in a well-baby nursery setting.
