Coumadin 7.5 mg is ordered for a patient with deep vein thrombosis. Coumadin 2.5 mg oral tablets are available in the electronic medication administration system on the nursing unit. How many tablets should the nurse administer to the patient?

To calculate the number of milliliters per minute the nurse should administer, you can set up a proportion based on the ordered dose and the concentration of the medication:

1 mL (containing 1 mg) is administered in 60 seconds (1 minute).

Now, you want to find out how many milliliters (mL) you need to administer for 5 mg in 60 seconds (1 minute).

Let's set up the proportion:

(1 mL / 1 mg) = (X mL / 5 mg)

To solve for X (the number of milliliters per minute):

X = (5 mg * 1 mL) / 1 mg = 5 mL / 1 = 5 mL

So, the nurse should administer 5 milliliters per minute to the patient.

A.It is the least painful location for this injection.
This statement is not necessarily true for everyone. Pain perception varies among individuals, and what might be the least painful site for one person might not be the same for another. Pain perception can also depend on factors such as the size of the needle, the technique of administration, and individual sensitivity.

B.There are fewer insulin side effects when given in this site.
The site of insulin administration (abdomen, thigh, arm) does not significantly affect the occurrence of side effects of insulin. Insulin side effects, such as hypoglycemia or allergic reactions, are related to the medication itself and individual patient factors, rather than the injection site.

C.There is steady absorption of insulin from this site.
This statement is correct, which makes it the preferred site for many people. However, the other choices incorrectly suggest reasons for this preference. The steady absorption from the abdomen is due to the consistent blood supply and tissue characteristics in this area.

D.It causes less bruising at the site.
The injection site does not solely determine the likelihood of bruising. Factors such as needle size, technique, and individual patient characteristics play a more significant role in whether bruising occurs. Bruising can happen at any injection site if proper techniques are not followed.
