Pharmacological & Parenteral Therapies Questions

Pharmacological and Parenteral Therapies is 13–19% of NCLEX-RN items (2026 test plan). Name what the stem asks about the drug, then check any number against its hold rule.

01 · Read the stemName it: effect, adverse effect, hold or teach

02 · The ruleNumber fails the parameter: hold and notify

03 · Reaction startsStop the infusion first, keep the IV access

How to pick the answer

Name the question, then check the number

Name what the stem asks: expected effect, adverse effect, hold rule or teaching

Look only for the finding that answers that question

Treat a number beside a drug as a give-or-hold check

Value fails the written parameter → hold the dose and notify the provider

A normal second value does not rescue a failed one

Check the rights: patient (two identifiers), drug, dose, route, time

Teach it · hold or act on it

Teach it

Opioid: pain relief and constipation are expected effects

ACE inhibitor: dry cough is a common side effect to teach about

Hold or act on it

Opioid: hard to rouse or RR under 12/min is the adverse effect to act on

ACE inhibitor: report a persistent cough (may switch to an ARB)

Any value that fails the written parameter: hold and notify

Real examples

Metoprolol → count the apical pulse 1 full minute; hold if under 60

Loop or thiazide diuretic → hold and notify if K⁺ under 3.5 (normal 3.5–5.0)

High-alert antidote: naloxone reverses opioids

High-alert antidote: protamine sulfate reverses heparin

High-alert antidote: vitamin K reverses warfarin

Insulin or heparin → second-nurse independent double-check

Follow the written hold parameter when one is ordered. On an opioid, sedation level catches trouble earlier than the respiratory rate.

When the answer is stop first

A reaction during an infusion: stop it, then keep the IV access

Chills, fever, back pain or hives in a transfusion → stop it stop first

Then run normal saline through new tubing

Notify the provider and blood bank; return the bag

Burning, swelling or pain at a vesicant site → stop the infusion extravasation

Aspirate the drug back per protocol, then notify the provider

Opioid patient hard to rouse or RR under 12/min act now

On the exam

13–19% of NCLEX-RN items (2026 NCSBN test plan)

Second only to Management of Care (15–21%)

NCSBN content here: expected effects, adverse effects and interactions, medication administration, dosage calculation, pain management, blood products, IV therapy, central lines and parenteral nutrition. Each exam's share can differ by up to ±3% from the stated range because the NCLEX-RN is adaptive and variable-length; NCSBN's chart shows about 16% for this category.

Pearl

Name what the stem asks, hold any dose whose number fails the parameter, and stop the infusion first when a reaction starts.
