A client is receiving intravenous (1V) vancomycin and the nurse plans to draw blood for a peak a. trough to determine the serum level of the drug. Which collection times provide the best determination of these levels?

Thirty minutes into the administration of the IV dose and 30 minutes before the next administration of the medication.

Two hours after completion of the IV dose 2nd 00 0000 before the next administration of the medication.

One how after completion of the IV dose and one hour before the next administration oldie medication.

Immediately after completion of the IV dose and 30 minutes before the next administration of the medication.

Answer and Explanation

The Correct Answer is D

A. Thirty minutes into the administration of the IV dose and 30 minutes before the next administration of the medication:

This timing doesn't align with the standard practice of drawing peak levels immediately after the IV dose is completed.

The trough level should be taken just before the next dose, not 30 minutes before.

B. Two hours after completion of the IV dose and 1 hour before the next administration of the medication:

Waiting for two hours after the dose to draw the peak level is too long. Peak levels are typically drawn immediately after completion.

Drawing the trough level one hour before the next dose doesn't provide an accurate assessment of the lowest drug concentration just before the next administration.

C. One hour after completion of the IV dose and one hour before the next administration of the medication:

Similar to choice B, waiting one hour after the dose to draw the peak level is not in line with standard practice.

Drawing the trough level one hour before the next dose is administered is too early to accurately represent the lowest concentration.

The best collection times for determining the peak and trough levels of intravenous (IV) vancomycin are:

D. Immediately after completion of the IV dose and 30 minutes before the next administration of the medication.

Explanation:

Peak Level: Peak levels of vancomycin are drawn immediately after the completion of the IV dose. This is done to assess the highest concentration of the drug in the bloodstream, which is important for ensuring its therapeutic efficacy and monitoring for potential toxicity.

Trough Level: Trough levels are drawn just before the next dose is administered. A trough level represents the lowest concentration of the drug in the bloodstream, ensuring that the drug is still present at a therapeutic level before the next dose is given. Taking the trough level 30 minutes before the next administration is appropriate, as it allows time for the drug to reach its lowest concentration before receiving the next dose.

Correct Answer is ["4"]

Explanation

To calculate the infusion rate in gtt/min, you can use the following formula:

Infusion rate (gtt/min) = (Volume to be infused (mL) / Time of infusion (min)) x Drop factor (gtt/mL)

In this case:

Volume to be infused = 500 mL

Time of infusion = 2 hours = 120 minutes (since 1 hour = 60 minutes)

Drop factor = 10 gtt/mL

Now, plug these values into the formula:

Infusion rate (gtt/min) = (500 mL / 120 min) x 10 gtt/mL

Infusion rate (gtt/min) = (5/12) x 10

Infusion rate (gtt/min) = 50/12

Infusion rate (gtt/min) ≈ 4.17 gtt/min

Rounded to the nearest whole number, the nurse should regulate the infusion at approximately 4 gtt/min.

A. Obtain a stool specimen to evaluate for occult blood and fat content. B. Instruct the client to increase her intake of saturated fats over the next week. C. Advise the client to stop taking the drug and contact her healthcare provider. D. Ask the client to describe her dietary intake history for the last several days.

Correct Answer is D

Explanation

A. Obtain a stool specimen to evaluate for occult blood and fat content:

While assessing stool content can provide valuable information, it is not the initial action needed in response to these side effects, which are commonly associated with orlistat use.

B. Instruct the client to increase her intake of saturated fats over the next week:

Increasing the intake of saturated fats is not a recommended action, especially when taking orlistat, as it may exacerbate the gastrointestinal side effects.

C. Advise the client to stop taking the drug and contact her healthcare provider:

While contacting the healthcare provider is important if the side effects are severe or persistent, the initial step should involve assessing the client's dietary choices and discussing possible dietary modifications before discontinuing the medication.

When a female client taking orlistat (a medication used for weight management) reports experiencing increasingly frequent oily stools and flatus, the nurse should take the following action:

D. Ask the client to describe her dietary intake history for the last several days.

Explanation: Oily stools and flatus are common side effects of orlistat, which works by blocking the absorption of dietary fat in the gastrointestinal tract. To assess the situation and provide appropriate guidance, the nurse should inquire about the client's dietary intake history. This will help determine if the side effects are related to the consumption of high-fat foods while taking the medication.
