A nurse is preparing to administer potassium chloride 20 mEq. The amount available is potassium chloride liquid 40 mEq/15 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["7.5"]
We can calculate the volume of potassium chloride solution to administer using the following steps:
Identify the prescribed dose: The nurse needs to administer 20 mEq of potassium chloride.
Identify the concentration of available solution: The potassium chloride liquid is available in a concentration of 40 mEq/15 mL. This means there are 40 milliequivalents (mEq) of potassium chloride in every 15 milliliters (mL) of the solution.
Set up a proportion to find the volume needed:
Desired dose (mEq) : Volume to administer (mL) = Concentration (mEq/mL)
Plug in the values:
20 mEq : Volume to administer (mL) = 40 mEq/15 mL
Solve for the volume:
To isolate the volume (mL), multiply both sides of the proportion by the volume unit (mL) and divide by the dose (mEq).
Volume to administer (mL) = (20 mEq) x (mL) / (40 mEq/15 mL)
We can simplify the calculation before dividing:
Volume to administer (mL) = (20 mEq x 15 mL) / 40 mEq
Volume to administer (mL) = 300 mL / 40 mEq
Volume to administer (mL) = 7.5 mL (round to one decimal place)
Therefore, the nurse should administer 7.5 mL of the potassium chloride solution.

Correct Answer is B
Explanation
A) Have suction equipment at the bedside:
Having suction equipment at the bedside is not specifically related to the administration of clopidogrel. It may be necessary for clients with respiratory or airway concerns but is not directly associated with this medication.
B) Monitor the client for black, tarry stools:
Clopidogrel is an antiplatelet medication that can increase the risk of bleeding, including gastrointestinal bleeding. Monitoring for black, tarry stools is essential as it can indicate upper gastrointestinal bleeding, which is a potential adverse effect of clopidogrel therapy.
C) Initiate contact precautions:
Contact precautions are not required for clients taking clopidogrel. Clopidogrel does not pose an infection risk that would necessitate contact precautions.
D) Administer the medication with each meal:
Clopidogrel is typically administered once daily, regardless of meals. There is no specific requirement to administer it with each meal.
Correct Answer is ["1"]
Explanation
To determine how many hydrochlorothiazide tablets to administer per dose, we can perform a simple calculation:
Identify the prescribed dose: The nurse needs to administer 25 mg of hydrochlorothiazide per dose.
Identify the tablet strength: Each available tablet contains 50 mg of hydrochlorothiazide.
Calculate the number of tablets: We need to find out how many 50 mg tablets are needed to deliver the prescribed 25 mg dose.
Here, dividing the prescribed dose by the tablet strength will tell us how many tablets are required:
Number of tablets = Prescribed dose / Tablet strength
Number of tablets = 25 mg / 50 mg/tablet
Since the division results in 0.5, we need to round to the nearest whole number for medication administration.
Therefore, the nurse should administer 1 tablet of hydrochlorothiazide per dose.
