How many questions are on the MACE and how long is it?
The MACE has 60 multiple-choice questions and a 120-minute time limit. Fifty questions count toward your score and ten are unscored pretest items mixed in — you cannot tell which is which, so answer every question carefully.
How is the MACE scored, and what score do I need?
The MACE uses a scaled score set by NCSBN, and the passing standard can vary by state board. Because the cut score is scaled rather than a simple percentage, focus on demonstrating competence across all three areas rather than chasing a specific percent — confirm your state’s requirement with your board or program.
What are the three content areas?
Medication Administration, Observation & Reporting (60%); Medication Concepts & Measurements (24%); and Authorized Duties (16%). The weighting tells you where to spend your time.

What the questions actually look like

The format is one thing; the questions are another. Here are three realistic examples.

Question 1

A Medication Aide is preparing to give a resident their scheduled over-the-counter pain reliever. Upon checking the bottle, the aide sees that the medication expired two months ago. What should the aide do?

▸ Why D is the answer

The aide must ensure medications are in-date during the standard checks; if expired, the correct action is to hold the drug and notify the nurse so a replacement can be ordered. It is a common misconception that over-the-counter medications do not expire, but no medication should ever be administered past its expiration date due to lost efficacy or chemical changes. Adjusting a dose might seem logical for a weakened drug, but a Medication Aide is never allowed to calculate or change a dose. Throwing the medication away immediately solves the immediate problem, but medications must be disposed of according to strict facility policy, never in a regular trash can, and the nurse must be notified first.

Question 2

Mr. Jones usually talks clearly and feeds himself, but today he is very confused, slurring his words, and unusually sleepy. He is scheduled to receive his routine morning medications. What should the Medication Aide do first?

▸ Why A is the answer

A sudden change in mental status (confusion, slurring, lethargy) is a significant change in condition that must be reported to the nurse immediately before giving any medications. Giving water might seem helpful to wake a resident, but giving any oral intake to an unusually sleepy and slurring resident poses a severe choking and aspiration risk. Crushing medications might make them seem easier to swallow, but it does not eliminate the aspiration risk for a lethargic resident, and crushing requires a specific order. Skipping the dose without notifying anyone avoids the choking risk, but it neglects the resident's potentially urgent medical situation which requires immediate nursing assessment.

Question 3

When checking the medication cart, the Medication Aide notices a bottle of liquid antibiotic that has a pharmacy sticker reading "Keep Refrigerated." The bottle has been sitting in the room-temperature cart since yesterday. What is the best action?

▸ Why B is the answer

Medications requiring refrigeration can lose effectiveness or spoil at room temperature; the aide must withhold the dose and notify the nurse so the pharmacy can be contacted for a safe replacement. Returning the bottle to the refrigerator seems like the right way to fix the error, but the medication has been left out for an extended period and may have already spoiled. Shaking liquid medications is often required, but it does not fix the fact that the medication was stored at the wrong temperature and may be degraded. Documenting the error is important, but administering improperly stored medication is unsafe and could result in the resident receiving an ineffective or harmful dose.
