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 C

Explanation

First, convert the client’s weight from pounds to kilograms: 121 lb /.2 = 55 kg. Then, calculate the dose in mg: 1 mg/kg * 55 kg = 55 mg.

Finally, use the ratio of available enoxaparin to calculate the volume to administer: (55 mg / 60 mg) * 0.6 mL = 0.55 mL.

Rounded to the nearest tenth, this is 0.6 mL.

Choice A is wrong because it is less than the calculated dose of 0.6 mL.

Choice B is wrong because it is equal to the calculated dose of 0.6 mL but not rounded to the nearest tenth.

Choice D is wrong because it is greater than the calculated dose of 0.6 mL.

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.
