Pharmacological & Parenteral Therapies Questions
What It Tests
Pharmacological and Parenteral Therapies is 13 to 19 percent of the exam, the second-largest category. NCSBN puts in it expected effects, adverse effects and interactions, medication administration, dosage calculation, pain management, blood products, IV therapy, central lines, and parenteral nutrition. On screen the item is a drug name you probably know followed by one of several different questions about it, sometimes with a number beside it, and sometimes no drug at all, only a line or a unit of blood with something going wrong.
Rule 1
Name what the stem asks about the drug: expected effect, adverse effect, hold rule, or teaching. The same drug has a different right answer for each asker, so decide before the options can pick one for you. Worked: "A client on an ACE inhibitor reports a dry cough the stem calls expected. Which action?" → teach that it is expected; expected earns teaching, never a hold.
Rule 2
A number next to a drug is a hold-or-give decision; if the rule fails, hold, then notify. The comparison is the whole item; a normal second number never rescues a failed rule. Worked: "Metoprolol due; hold for an apical pulse below 60. The nurse counts 54; blood pressure is 118/72." → hold the dose and notify; give and recheck in an hour is the miss.
Rule 3
Stop what is running before you call anyone. Every second the bag, unit, or line keeps going adds harm, and no assessment or call can undo it. Worked: "Fifteen minutes into a unit of packed red cells the client reports chills and back pain. Which action first?" → stop the transfusion; slowing it, assessing, or calling the provider first is the miss.
What to Review
Clinical Pearl
Name what the stem asks about the drug, compare every number to its hold rule, and stop what is running before you call.
