Pharmacological & Parenteral Therapies 4

Welcome to this NCLEX-RN practice test for Pharmacological & Parenteral Therapies. One of the main responsibilities of a Registered Nurse is to safely administer medications, following the Ten Rights of Medication Administration. Your NCLEX test items will include 12-18% on this content, to determine of you are capable of calculating dosages for any route of administration, including intravenous infusions. You are also expected to understand high-risk medications and controlled substances, the complete process of blood product administration, and evaluating client responses to therapies. This practice test includes questions on proper insulin administration, dosage calculations, laboratory values, IV solutions, over-the-counter (OTC) medications, and client education. You can begin this test at any time. If you leave any test before it’s completed, it will remind you where you left off when you return. A good strategy is to read each question carefully and try to think of the answer before looking at the options. Remember that you should select the BEST choice; the correct answer is always there. If you’re not sure, click on the Hint button under the fourth option to get a clue. When you select the correct response, you’ll go the next question. If you make a mistake, an explanation will immediately pop up with the rationale for the answer. Each time you take a practice test, the questions and options are shuffled into a different random order. These are two proven techniques to reinforce your learning.
