The LPN/LVN prepares to administer the initial doses of furosemide (Lasix) to a client. It is MOST important for the LPN/LVN to review the client's chart for which of the following client data?

1. Allergy to sulfa drugs.
2. Intake and output for the previous 24 hours.
3. Admission weight and current weight.
4. Signs/symptoms of infection.

The correct answer is 1. Allergy to sulfa drugs.

Explanation:

Furosemide is a loop diuretic and it is given in patients with hypertension and in treatment of edemas.

If a patient is allergic to sulfa or sulfonamides, then the patient may also be allergic to furosemide. So the doctor must ask the patient if he is allergic to any drug.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
