Correct Answer is D

Explanation

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.

A. Subcutaneous insulin injections. B. Bicarbonate by IV infusion. C. 0.9% sodium chloride 15 m/kg/hr. D. Potassium chloride 10 mEq/hr.

Correct Answer is C

Explanation

The first intervention for a client with diabetic ketoacidosis and a blood glucose level of 800 mg/dL should be to initiate fluid replacement therapy with 0.9% sodium chloride at a rate of 15 mL/kg/hr.

This will help to replace fluids lost through excessive urination and to dilute the excess sugar in the blood.

Choice A is wrong because subcutaneous insulin injections are not the first intervention for diabetic ketoacidosis.

Insulin therapy is generally given intravenously.

Choice B is wrong because bicarbonate by IV infusion is not the first intervention for diabetic ketoacidosis.

Choice D is wrong because potassium chloride at a rate of 10 mEq/hr is not the first intervention for diabetic ketoacidosis.

Electrolyte replacement may be necessary to replace minerals such as sodium, potassium, and chloride, but this is not the first intervention 2.
