Pharmacological & Parenteral Therapies 4
- Based on the official NCLEX-RN exam guidelines
- Updated for June 2026
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.
- Perfect for nursing students and professionals preparing for the NCLEX exam

How we keep NCLEX practice questions accurate
Our NCLEX practice tests are built around the written knowledge exam and the skills topics nurse aide candidates are expected to know.
Written by Andrei Zakhareuski
Updated over a week ago
At Nurse.plus, we review question wording, answer choices, and explanations against current nurse aide exam topics instead of treating old quiz banks as final.
Here's how we keep the practice tests useful and reliable.
Content creation and review process
-
Exam alignment:
We map practice questions to core NCLEX exam areas, including basic nursing skills, infection control, residents' rights, safety, communication, and personal care. -
Clear explanations:
Each question is checked for plain language, answer-choice clarity, and an explanation that helps after a wrong answer. -
Foundational nursing review:
Winona Suzanne Ball, RN, MHS, helped establish the nursing review standards behind Nurse Plus. New updates are maintained by the Nurse.plus content team and checked before publication. -
Editorial QA:
Before a question goes live, we review the clinical point, the distractors, formatting, proofreading, and whether the item fits the test it appears in. -
User feedback:
Every question can be reported from the test screen. When a learner flags wording, an answer choice, or a rationale, we review it and update the item when needed. -
Ongoing updates:
We refresh examples, explanations, and provider references as NCLEX testing guidance changes.
That process is not flashy, but it matters: learners need practice questions that read like the exam and explanations that actually help after a missed answer.
