A.

75 mLs

B.

5 mLs

C.

6 mLs

D.

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 A

Explanation

Choice A rationale:

Hypoglycemia, also known as low blood sugar, is a condition where blood sugar levels fall below the standard range. It is often related to diabetes treatment. When blood glucose levels are too low, individuals may experience symptoms such as shakiness, which is why the statement “I will feel shaky” indicates an understanding of the manifestations of hypoglycemia.

Choice B rationale:

The statement “My skin will be warm and moist” does not accurately represent the symptoms of hypoglycemia. While sweating can be a symptom of hypoglycemia, it does not necessarily mean that the skin will feel warm and moist. Therefore, this choice does not indicate a correct understanding of the manifestations of hypoglycemia.

Choice C rationale:

The statement “I will be more thirsty than usual” is more commonly associated with hyperglycemia, or high blood sugar, rather than hypoglycemia. Thirst is not typically a symptom of low blood sugar. Therefore, this choice does not indicate a correct understanding of the manifestations of hypoglycemia.

Choice D rationale:

The statement “My appetite will be decreased” is not a typical symptom of hypoglycemia. In fact, hunger is a common symptom of low blood sugar. Therefore, this choice does not indicate a correct understanding of the manifestations of hypoglycemia.
