A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis. Available is heparin 10,000 units/mL. How many mL of heparin should the nurse administer?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.4"]

To answer this question, we need to use the formula for calculating the dosage of medication:

Dose ordered / Dose on hand = Amount to administer

The calculation is: 4,000 units / 10,000 units/mL = 0.4 mL.

Correct Answer is ["7.5"]

Explanation

The correct answer is 7.5 ML

To answer this question, we need to use the formula:

mL to administer = (mEq ordered / mEq available) x mL available Plugging in the values from the question, we get:

mL to administer = (20 mEq/day / 6.7 mEq/5 mL) x 5 mL Simplifying, we get:

mL to administer = (2.99 mL/mEq) x 5 mL Multiplying, we get:

mL to administer = 14.95 mL/day

Since the order is to divide the dose equally every 12 hours, we need to divide the total daily dose by 2:

mL to administer per dose = 14.95 mL/day / 2 Dividing, we get:

mL to administer per dose = 7.475 mL

Rounding to the nearest tenth, we get:

mL to administer per dose = 7.5 mL

Therefore, the nurse should administer 7.5 mL of potassium chloride elixir per dose.

A. Red man syndrome B. Hypotension C. Hypoglycemia D. Bradycardia

Hypotension can be an adverse effect of phenytoin administration, especially if the medication is administered rapidly.

Choice C rationale:

Hypoglycemia is not commonly associated with phenytoin use.

Choice D rationale:

Bradycardia is not commonly associated with phenytoin use.
