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:

Erythromycin Erythromycin is a macrolide antibiotic that is often used as an alternative to penicillin. It is generally safe for use in patients with a penicillin allergy. It works by inhibiting bacterial protein synthesis and is effective against a wide range of bacteria.

Choice B rationale:

Amphotericin B Amphotericin B is an antifungal medication, not an antibiotic. It is used to treat serious, systemic fungal infections. It has no cross-reactivity with penicillin, so it would not be a concern for a patient with a penicillin allergy.

Choice C rationale:

Amoxicillin-clavulanate Amoxicillin-clavulanate is a type of penicillin antibiotic. Patients with a known penicillin allergy should avoid this medication, as they may have a cross-reactivity to it. This is why the nurse should verify this prescription with the provider.

Choice D rationale:

Gentamicin Gentamicin is an aminoglycoside antibiotic used to treat serious bacterial infections caused by gram-negative bacteria. It is not related to penicillin and would be safe for a patient with a penicillin allergy.

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.
