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 D
Explanation
A) "It’s a good idea to help make sure your husband can sleep comfortably":
While the partner's intention may be to ensure the client's comfort, PCA pumps are designed for the client to self-administer medication according to their own pain level. Allowing the partner to administer doses without the client's input may lead to overmedication or misuse of the PCA pump.
B) "Next time you think he needs more medication, call me and I’ll push the button":
This response encourages the partner to involve the nurse in determining when additional medication is needed, which is appropriate. However, the ideal approach with a PCA pump is for the client to self-administer doses based on their own pain assessment and to communicate directly with the nurse if assistance is needed.
C) "Why do you think your husband needs more medication when he is asleep?":
This response may come across as confrontational and could imply mistrust in the partner's actions. It's important to address the situation without causing discomfort or defensiveness.
D) "Your husband should decide when more medication is needed":
This is the correct response because PCA pumps are specifically designed for the client to control their pain management. The client is encouraged to use the PCA pump to administer medication when they feel they need it, based on their own pain assessment. The partner's role should be to support and assist the client as needed, rather than making decisions about medication administration.
