The most common adverse effect of epoetin alfa is:

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.

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.
