A nurse is preparing to administer potassium chloride 30 mEq PO daily. The amount available is potassium chloride 20 mEq/15mL. How many mL should the nurse administer?

(Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["23"]

To determine how many milliliters (mL) of potassium chloride the nurse should administer to provide 30 mEq, we can set up a proportion:

20 mEq is contained in 15 mL. So, to find out how many mL contain 30 mEq, we can set up the proportion:

20 mEq:15 mL=30 mEq:𝑥 mL20mEq:15mL=30mEq:xmL

Cross multiply:

20×𝑥=15×3020×x=15×30

20𝑥=45020x=450

Now, solve for 𝑥x:

𝑥=45020x=20450

𝑥=22.5x=22.5

So, the nurse should administer approximately 22.5 mL of potassium chloride.

Rounded to the nearest whole number, this would be 23 mL.

Therefore, the nurse should administer 23 mL of potassium chloride.

Correct Answer is D

Explanation

A. Most CAM therapies are not totally ineffective: While some CAM therapies may lack strong scientific evidence, it's not accurate to say they are all ineffective. Some CAM therapies may have benefits, but it's important to be aware of them to avoid interactions.

B. Not all CAM therapies are dangerous: Many CAM therapies are generally safe. However, some can interact with medications or have unforeseen side effects, so assessing use is crucial.

C. Additional treatment may still be needed: Even if a patient uses CAM, they might still require conventional medical treatment. Assessing CAM use helps ensure a complete picture of the patient's healthcare regimen.

D. CAM therapies could interact with prescription and OTC medications. Correct. The primary reason to assess CAM use is to identify potential interactions with medications, potentially improving patient safety and treatment effectiveness.

Correct Answer is ["7"]

Explanation

Dosage (mL) = Desired dose (mg) / Concentration (mg/mL)

Dosage (mL) = 350 mg / (250 mg/5 mL)

Dosage (mL) = 7 mL (rounded to nearest whole number)

Therefore, the nurse should administer 7 mL of amoxicillin suspension.
