The nurse should identify that which of the following medications is contraindicated for this client?

Vancomycin.

Clarithromycin.

Metronidazole.

Ceftriaxone.

Answer and Explanation

The Correct Answer is D

Ceftriaxone is contraindicated for this client because it is a cephalosporin antibiotic, which has a similar structure to penicillin and can cause cross-reactivity in individuals with a penicillin allergy.

Choice A is wrong because Vancomycin is not a beta-lactam antibiotic and does not have cross-reactivity with penicillin.

Choice B is wrong because Clarithromycin is a macrolide antibiotic and does not have cross-reactivity with penicillin.

Choice C is wrong because Metronidazole is a nitroimidazole antibiotic and does not have cross-reactivity with penicillin.

Correct Answer is D

Explanation

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.

A. Hypotension. B. Extravasation. C. Headache. D. Chest pain.

Correct Answer is A

Explanation

Dopamine is a medication used to treat hypotension, low cardiac output, and poor perfusion of vital organs.

It is used to increase mean arterial pressure in septic shock patients who remain hypotensive after adequate volume expansion 1.

If the client is still experiencing hypotension while receiving dopamine by continuous IV infusion, the nurse should increase the rate of infusion to improve the client’s blood pressure.

Choice B is wrong because Extravasation, is not the correct answer because it refers to the leakage of IV fluid or medication into the surrounding tissue and is not an indication to increase the rate of dopamine infusion.

Choice C is wrong because Headache, is not the correct answer because it is not specifically related to dopamine therapy or an indication to increase the rate of infusion.

Choice D is wrong because Chest pain, is not the correct answer because it is not specifically related to dopamine therapy or an indication to increase the rate of infusion.
