Peds math calculations on nclex!

Published

My friend recently took nclex, she told me that she had peds math calculation questions, no she did not tell me specifics! But she told me that she kept getting similar peds math calc, she was wondering if she maybe got them wrong and that nclex kept asking her similar questions to see if she knew what she was doing....any comments on why she kept getting peds math calc, did she get them wrong??

Just a question, were these repeat questions exactly the same and asked multiple times? does this mean you answered it wrong the first time?

does anyone know how to answer this peds sample question? it is driving me crazy, i just could not figure it out on my own. thanks in advance

The nurse is caring for a client who has a prescription for gentamicin (Garamycin) 2 mg/kg, IV, every 8 hours. The client weighs 143 lb. The nurse has Garamycin 100 mg in 50 ml of solution available. How many ml should the nurse administer to the client with each dose?

CORRECT ANSWER 65 ml

CORRECT ANSWER 65 ml

1. 143 lbs/ 2.2 kg= 65 kg x 2 mg/kg= 130 mg

2. 100 mg/ 50 ml = 2mg/ ml

3. 130 mg divide 2 mg/ml = 65 mg

Thats how i solved the problem

It is a reasonable assumption that when a question is asked in different forms several times, that the tester got it wrong the first time. I distinctly remember this on my test. I did not know the answer the first time and most likely got it wrong the subsequent times it was asked, using different wording. It did not occur to me to answer the question differently.
