Simulated
A nurse is preparing to administer 18 units of mixed insulin (NPH/Regular 50/50) for a client with type 2 diabetes. How many units of NPH will the client receive per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
9
Rationale
The correct answer is 9 units of NPH. Since the mixed insulin is 50/50 NPH/Regular, 18 units total means half of it, which is 9 units, will be NPH. Regular insulin will also be 9 units, making the total 18 units. Therefore, the client will receive 9 units of NPH per dose. Other choices are incorrect because they do not reflect the correct calculation based on the ratio of the mixed insulin given.
