The physician orders an injection of dexamethasone (Decadron) 6mg IM for a patient.

The available stock is dexamethasone 4mg/1ml in a 5ml multidose vial.

How many mLs of this medication will the nurse prepare?

75 mLs

5 mLs

6 mLs

15 mLs

Answer and Explanation

The Correct Answer is C

The correct answer is Choice C.

Let’s go through the calculation step by step:

Step 1: Identify the order and the available medication. The order is for dexamethasone (Decadron) 6mg IM. The available stock is dexamethasone 4mg/1ml in a 5ml multidose vial.

Step 2: Determine the amount of medication needed to fulfill the order. This is done by dividing the ordered amount by the concentration of the available medication.

So, we have:

Step 2 Calculation=Concentration of Available MedicationOrdered Amount Substituting the given values: Step 2 Calculation=4 mg/mL6 mg Step 3: Perform the calculation.

Step 3 Calculation=1.5 mL

So, the nurse will prepare 1.5 mL of this medication.

Now, let’s discuss the rationales for each choice:

Choice A rationale:

75 mLs is not the correct amount. This would be a significantly larger dose than ordered, which could lead to an overdose.

Choice B rationale:

5 mLs is not the correct amount. This would also be a larger dose than ordered, which could lead to an overdose.

Choice C rationale:

1.5 mLs is the correct amount. This is calculated by dividing the ordered dose (6 mg) by the concentration of the available medication (4 mg/mL).

Choice D rationale:

15 mLs is not the correct amount. This would be a significantly larger dose than ordered, which could lead to an overdose.

Correct Answer is C

Explanation

Choice A rationale:

Fluconazole Fluconazole is an antifungal medication used to treat and prevent fungal infections. It works by stopping the growth of certain types of fungus. However, it is not effective against bacterial infections such as anthrax.

Choice B rationale:

Tobramycin Tobramycin is an aminoglycoside antibiotic used to treat various types of bacterial infections, particularly Gramnegative infections. It works by stopping the growth of bacteria. However, it is not typically used to treat anthrax.

Choice C rationale:

Ciprofloxacin Ciprofloxacin is a fluoroquinolone antibiotic used for the treatment of a number of bacterial infections. This includes bone and joint infections, intra-abdominal infections, certain type of infectious diarrhea, respiratory tract infections, skin infections, typhoid fever, and urinary tract infections, among others. For the treatment of anthrax, ciprofloxacin is one of the antibiotics that could be used. It works by killing the anthrax or by stopping the anthrax from growing. When the anthrax can’t grow anymore, it dies.

Choice D rationale:

Vancomycin Vancomycin is an antibiotic used to treat a number of bacterial infections. It is recommended intravenously as a treatment for complicated skin infections, bloodstream infections, endocarditis, bone and joint infections, and meningitis caused by methicillin-resistant Staphylococcus aureus. However, it is not typically used to treat anthrax.

A. Polyuria B. Sweating C. Tachycardia D. Blurry vision

Correct Answer is ["B","C","D"]

Explanation

Choice A rationale:

Polyuria, which is frequent or excessive urination, is not typically a symptom of hypoglycemia. It is more commonly associated with hyperglycemia, or high blood sugar levels.

Choice B rationale:

Sweating is indeed a common symptom of hypoglycemia. When blood sugar levels fall too low, the body may respond by sweating as it releases adrenaline in response to the hypoglycemic state.

Choice C rationale:

Tachycardia, or a fast heartbeat, is another common symptom of hypoglycemia. This is part of the body’s response to low blood sugar levels, as it releases adrenaline to try to raise these levels.

Choice D rationale:

Blurry vision can be a symptom of hypoglycemia. When blood sugar levels fall, it can affect the ability of the eyes to focus, leading to blurry vision.

Choice E rationale:

Polydipsia, or excessive thirst, is not typically a symptom of hypoglycemia. Like polyuria, it is more commonly associated with hyperglycemia.
