Answer and Explanation

Correct Answer : B,D,E,F

E. Are you taking any supplements? - High potassium levels can sometimes be related to potassium-containing supplements, so it's essential to inquire about any supplements the client may be taking.

F. Do you use any salt substitutes? - High potassium levels can be caused by the excessive use of salt substitutes, which often contain potassium chloride.

A. Have you experienced itching or hives? - While itching or hives can be associated with various conditions, these symptoms may not be directly related to the specific lab results mentioned.

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.

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.
