We know figuring out doses is a challenge for nursing candidates. They get anxious about calculations -- for good reason. It can be a lot to figure out, especially with the time constraints of the actual NCLEX. A lot of our customers have asked for more drug dosage calculation questions, and we listened. After all, the more you can practice, the more confident you’ll be for your exam. We’ve prepared a separate test that contains 50 Pharmacological Dosage Calculation problems for NCLEX-RN -- hopefully you’ll find it super-challenging. Here they are -- 50 Pharmacological Calculation problems. We provide a formula for each one. Included: Dosages, IV rates, drug reconstitution, common measurements, and percentage strength.
