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 C

Explanation

Fentanyl buccal film is a small film that sticks to the inside of the cheek and eventually dissolves within 15 to 30 minutes after it is applied.

It is used to manage breakthrough pain in patients with cancer who are already using another opioid pain medicine around-the-clock.

Choice A is wrong because the medication should not be placed on the client’s tongue for dissolution.

Choice B is wrong because the medication should not be dissolved in water before administering it.

Choice D is wrong because the client should not be instructed to swallow the medication with a sip of water.

A. Avoid massaging the site after injection. B. Inject the medication into the abdomen. C. Administer the medication through clothing if necessary. D. Aspirate prior to administration of the medication.

Correct Answer is C

Explanation

The nurse should instruct the client to administer the medication through clothing if necessary.

In an emergency, an epinephrine auto-injector can be given through clothing.
Choice A is wrong because massaging the site after injection is not mentioned as something to avoid in the instructions for using an epinephrine auto-injector.
Choice B is wrong because the medication should be injected into the outer thigh, not the abdomen.
Choice D is wrong because aspiration prior to administration of the medication is not mentioned as a necessary step in the instructions for using an epinephrine auto-injector.
