A nurse is providing discharge teaching about warfarin to a client who has deep- vein thrombosis.
The nurse should instruct the client to obtain which of the following laboratory tests monthly?

Platelet count.

aPTT.

Fibrinogen.

INR.

Answer and Explanation

The Correct Answer is D

A client who has deep-vein thrombosis and is taking warfarin should obtain an International Normalized Ratio (INR) test monthly.

This blood test measures how fast the blood clots and helps the healthcare provider determine if the client is taking the right dose of warfarin to keep them safe from bleeding and making clots.

Choice A is wrong because Platelet count, is not the correct answer because it measures the number of platelets in the blood and is not specifically related to warfarin therapy.

Choice B is wrong because aPTT, is not the correct answer because it measures the time it takes for blood to clot and is used to monitor heparin therapy, not warfarin therapy.

Choice C is wrong because Fibrinogen, is not the correct answer because it measures the amount of fibrinogen in the blood and is not specifically related to warfarin therapy.

Correct Answer is A

Explanation

Total parenteral nutrition (TPN) is a method of administration of essential nutrients to the body through a central vein.

TPN solutions are customized for each client’s needs, including the exact amount of calories and nutrients necessary for total nutritional needs.
Monitoring the client’s weight daily is important to determine if nutritional goals are being met and to assess fluid volume status.
Choice B is wrong because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so they require a central venous catheter and should not be hung to gravity to infuse.
Choice C is wrong because TPN solution should not be titrated to blood pressure.
Choice D is wrong because the client’s blood glucose level should be monitored more frequently than weekly when receiving TPN.

A. "I will limit potassium-rich foods in my diet.” B. "I will take the medication on an empty stomach.” C. "I will use salt substitutes in place of table salt.” D. "I will double up on my medication if I miss a dose.”

Correct Answer is A

Explanation

Spironolactone is a potassium-sparing diuretic that can increase potassium levels in the blood.

It is important for clients taking spironolactone to limit their intake of potassium-rich foods to prevent hyperkalemia (high potassium levels).

Choice B is wrong because “I will take the medication on an empty stomach,” is not the correct answer because spironolactone can be taken with or without food.

Choice C is wrong because “I will use salt substitutes in place of table salt,” is not the correct answer because many salt substitutes contain potassium and can increase the risk of hyperkalemia.

Choice D is wrong because “I will double up on my medication if I miss a dose,” is not the correct answer because it is not recommended to double up on medication if a dose is missed.
