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.)
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:? mL20mEq:15mL=30mEq:xmL
Cross multiply:
20×?=15×3020×x=15×30
20?=45020x=450
Now, solve for ?x:
?=45020x=20450
?=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 ["B","C"]
Explanation
A. Constipation: Constipation is not a commonly reported adverse effect of clopidogrel (Plavix). Clopidogrel is an antiplatelet medication that works by inhibiting platelet aggregation, and gastrointestinal effects such as constipation are not typically associated with its use.
B. Bruising: This is a correct answer. Bruising is a known adverse effect of clopidogrel. As an antiplatelet medication, clopidogrel inhibits platelet aggregation, which can increase the risk of bleeding and bruising.
C. Rash: Rash is a potential adverse effect of clopidogrel, although it is not as common as other side effects such as bruising or gastrointestinal symptoms. Patients taking clopidogrel should be monitored for signs of allergic reactions, including rash, which may indicate the need for further evaluation or discontinuation of the medication.
D. Headache: Headache is not a commonly reported adverse effect of clopidogrel. While some patients may experience headache while taking clopidogrel, it is not considered a frequent or significant side effect of the medication.
E. Diarrhea: Diarrhea is not a commonly reported adverse effect of clopidogrel. Gastrointestinal symptoms such as diarrhea are not typically associated with clopidogrel use, although some patients may experience gastrointestinal upset as a side effect of antiplatelet therapy.
Correct Answer is D
Explanation
A. Most CAM therapies are totally ineffective: Incorrect. Dismissing all CAM therapies as ineffective without considering individual cases could lead to overlooking potentially helpful treatments for patients.
B. Additional treatment may not be needed: Incorrect. Collecting information about CAM use allows healthcare providers to assess the overall treatment regimen comprehensively.
C. Patients must be warned that most CAM therapies are dangerous: Incorrect. While some CAM therapies may carry risks, it's not accurate to generalize that most CAM therapies are dangerous.
D. CAM therapies could interact with prescription and OTC medications: Correct. Understanding potential interactions between CAM therapies and conventional medications is essential for patient safety and optimal treatment outcomes.
