A nurse is about to administer a daily dose of potassium chloride 20 mEq suspension orally.
The available amount is potassium chloride suspension 10 mEq/mL.
How many mL should the nurse administer?
The Correct Answer is ["2"]
Step 1: Determine the amount of medication needed. The order is for 20 mEq of potassium chloride. The available amount is 10 mEq/mL.
Step 2: Calculate the volume of medication to administer. Volume = Ordered dose ÷ Available concentration Volume = 20 mEq ÷ 10 mEq/mL = 2 mL So, the nurse should administer 2 mL of potassium chloride suspension.

Correct Answer is B
Explanation
Choice A rationale
Cleaning the inside of the container with a wipe is not recommended. The container provided for a urine sample is sterile, and cleaning it could introduce bacteria, contaminating the sample.
Choice B rationale
The statement “I will urinate a little then stop” is correct. This is part of the process of collecting a midstream urine sample. The initial stream of urine can contain bacteria from the urethra or genital area, so it’s recommended to start urinating, then stop and collect the sample midstream.
Choice C rationale
The statement “I will use each cleansing wipe twice” is incorrect. Each cleansing wipe should only be used once to avoid reintroducing bacteria.
Choice D rationale
The statement “I will use the cleansing wipe from front to back” is correct. This is the proper way to clean the genital area to avoid introducing bacteria from the anal area into the urethra.
Correct Answer is D
Explanation
Choice A rationale
Glucocorticoid medications are not typically used in the treatment of diabetic ketoacidosis (DKA). These medications can actually increase blood glucose levels, which would not be beneficial in a situation where blood glucose is already significantly elevated.
Choice B rationale
Dextrose 5% in 0.45% sodium chloride is not typically used in the initial treatment of DKA. This solution contains glucose, which would add to the already high blood glucose levels in DKA5.
Choice C rationale
Oral hypoglycemic medications are not typically used in the treatment of DKA. These medications are generally used in the management of type 2 diabetes. In DKA, which is more common in type 1 diabetes, insulin is usually required to lower blood glucose levels.
Choice D rationale
A 0.9% sodium chloride IV bolus is often part of the initial treatment for DKA. This helps to replace the fluid lost through excessive urination, a common symptom of DKA5.
