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

This is because pioglitazone can cause fluid retention and edema.

Choice B is wrong because tinnitus (ringing in the ears) is not a common adverse effect of pioglitazone.

Choice C is wrong because insomnia (difficulty sleeping) is not a common adverse effect of pioglitazone.

Choice D is wrong because orthostatic hypotension (a drop in blood pressure when standing up) is not a common adverse effect of pioglitazone.

A. "Administer the medication into one nostril once per week.” B. "Lie down for 1 hour after administering the medication.” C. "Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose.” D. "Plan to self-administer this medication for the next 6 months.”

Correct Answer is A

Explanation

Nasal cyanocobalamin is a form of vitamin B12 that is used to treat pernicious anemia.

It is typically administered once per week into one nostril.

Choice B is wrong because there is no need to lie down for 1 hour after administering the medication.

Choice C is wrong because using a nasal decongestant before administering the medication is not necessary and may interfere with the absorption of the medication.

Choice D is wrong because the duration of treatment with nasal cyanocobalamin varies and should be determined by the provider based on the client’s individual needs.
