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.) mL.

Answer and Explanation

The Correct Answer is ["0.4"]

To calculate the amount of heparin to administer, use the formula:

mL of heparin=units available units ordered×1mL available

Substituting the values given in the question, we get:

mL of heparin=100004000×11=0.4

Therefore, the nurse should administer 0.4 mL of heparin.

Normal ranges for heparin therapy vary depending on the condition being treated and the laboratory method used to measure APTT.

A general range is 60 to 80 seconds or 1.5 to 2.5 times the control value.

Correct Answer is B

Explanation

This is because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so a central venous catheter is usually required. TPN should only be used when the intestine is unavailable or unable to absorb nutrients.

Choice A is wrong because a midline catheter is a type of peripheral catheter that can only be used for solutions with low or moderate osmolarity, not for TPN.

Choice C is wrong because subcutaneous administration is not a route for delivering TPN, which requires intravenous infusion.

Choice D is wrong because intraosseous administration is an emergency route for delivering fluids and drugs when intravenous access is not available, not for TPN.

A. Apply pressure to the IV site. B. Elevate the extremity. C. Slow the infusion rate. D. Flush the IV catheter.

Correct Answer is B

Explanation

This will help reduce swelling and discomfort caused by the infiltration of fluid into the tissues. Elevating the extremity also promotes venous return and prevents further fluid accumulation.

Choice A is wrong because applying pressure to the IV site can increase the risk of tissue damage and infection.

Pressure can also obstruct blood flow and cause thrombophlebitis.

Choice C is wrong because slowing the infusion rate will not stop the infiltration of fluid into the tissues.

Slowing the infusion rate can also delay the delivery of medication or fluid to the client.

Choice D is wrong because flushing the IV catheter can worsen the infiltration of fluid into the tissues.

Flushing the IV catheter can also introduce air or bacteria into the bloodstream and cause complications.

Normal ranges for peripheral IV infusion are dependent on the type and volume of fluid, the size and location of the catheter, and the condition of the client. Generally, peripheral IV infusion rates should not exceed 100 mL/hr for adults and 60 mL/hr for children.
