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 D

Explanation

Choice A rationale:

Acyclovir is an antiviral medication used to treat infections caused by certain types of viruses. It is primarily used for the treatment of herpes simplex virus infections, chickenpox, and shingles. However, it is not typically used as an anti-HIV drug.

Choice B rationale:

Ribavirin is an antiviral medication used to treat hepatitis C and certain other viral infections. While it has broad-spectrum antiviral activity, it is not specifically used to prevent mother-to-child transmission of HIV.

Choice C rationale:

Foscarnet is an antiviral medication used to treat or prevent cytomegalovirus (CMV) retinitis in individuals with AIDS. It is also used to treat cold sores and genital herpes. However, it is not the first-line choice for preventing mother-to-child transmission of HIV.

Choice D rationale:

Zidovudine, also known as AZT, is an antiretroviral medication used to prevent and treat HIV/AIDS. It is generally safe for use during pregnancy and is commonly used to prevent mother-to-child transmission of HIV12. It works by inhibiting the reverse transcriptase enzyme, thereby blocking viral replication. The use of Zidovudine and other antiretroviral drugs in pregnant women with HIV has significantly reduced the rate of mother-to-child transmission of the virus.

Correct Answer is ["2.5 "]

Explanation

Step 1: Identify the given values. The nurse needs to administer 2.5 mg of hydromorphone. The available amount is 5 mg/5 mL.

Step 2: Set up the calculation. We need to find out how many mL correspond to 2.5 mg. We can set up a proportion using the given values:

5 mL5 mg=x mL2.5 mg

Step 3: Solve for x. Cross-multiply and solve for x:

5 mg×x mL=2.5 mg×5 mL

Step 4: Simplify the equation:

x=5 mg.5 mg×5 mL

Step 5: Calculate the value of x:

x=2.5 mL

So, the nurse should administer 2.5 mL of the hydromorphone elixir.
