How much of the NCLEX-RN is Pharmacological and Parenteral Therapies?

13–19% of the items, under the 2026 NCLEX-RN Test Plan. The exam is adaptive — between 85 and 150 items — so the count you meet depends on how long your exam runs.

Is there a passing score on the NCLEX?

Not as a percentage. The exam is computer-adaptive and ends when the computer is 95% sure your ability is above or below the passing standard, a level NCSBN sets rather than a number of correct answers.

Is this the official NCLEX?

No. These are original practice questions written for study from the categories in the published test plan. The official exam is administered by NCSBN (National Council of State Boards of Nursing).

NCLEX-RN — Pharmacological and Parenteral Therapies Question 1 of 10

A client receiving warfarin has an INR of 8.0 with visible bleeding. Which medication should the nurse anticipate?

What this section asks

The second-heaviest category and the one candidates fear most, because it feels like memorising a pharmacy. The exam is narrower than that: the rights of medication administration, dosage calculation, what to check before giving a drug, how to recognise the adverse effect that matters, and how to run and monitor an IV line or a blood transfusion. Know the high-alert drugs and their antidotes cold.
