The nurse is administering liquid medications through a percutaneous endoscopic gastrostomy (PEG) tube.
Which technique is correct?

Administering the medications using a 3-mL medication syringe

Applying firm pressure on the syringe’s piston to infuse the medication

Flushing the tubing with 30 mL of saline after the medication has been given

Using the barrel of the syringe, allowing the medication to flow via gravity into the tube

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Administering the medications using a 3-mL medication syringe is not the best practice. While it is possible to use a 3-mL syringe for medication administration, it is not the most efficient or safest method. A larger syringe allows for easier administration and reduces the risk of creating too much pressure which could potentially damage the PEG tube.

Choice B rationale:

Applying firm pressure on the syringe’s piston to infuse the medication is not recommended. This can create too much pressure in the PEG tube and could potentially cause damage. It is generally advised to allow the medication to flow into the tube via gravity. Choice C rationale:

Flushing the tubing with 30 mL of saline after the medication has been given is the correct technique. This helps to ensure that all of the medication has been administered and also helps to keep the tube clear of any potential blockages.

Choice D rationale:

Using the barrel of the syringe, allowing the medication to flow via gravity into the tube is a common practice. However, it is not the only step in the process. It is also important to flush the tube before and after medication administration to ensure all medication is delivered and to maintain the patency of the tube.

Correct Answer is C

Explanation

Choice A rationale:

This choice is incorrect. While it’s true that antiviral drugs can be effective in treating the flu, they’re most effective when started within 48 hours of symptom onset. Starting treatment after 4 days may not provide the same benefits.

Choice B rationale:

This choice is incorrect. While a blood test can confirm the presence of the flu virus, it’s not typically necessary to diagnose the flu. Diagnosis is usually based on symptoms and the fact that the flu is widespread in the community.

Choice C rationale:

This choice is correct. Antiviral drugs are most effective when started within 2 days of symptom onset. After this time, the benefits of these drugs decrease. Therefore, starting treatment 4 days after symptoms begin may not significantly reduce the duration or severity of symptoms.

Choice D rationale:

This choice is incorrect. While it’s true that getting a flu vaccine is important, it’s not the best response in this situation. The flu vaccine won’t treat current illness. It’s designed to prevent future infections. In this case, the individual is already sick, so a booster vaccination wouldn’t be the most effective course of action.

A. 75 mLs B. 5 mLs C. 6 mLs D. 15 mLs

Correct Answer is C

Explanation

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.
