Test yourself: 3 MACE practice questions

Tap an answer for instant feedback and the full rationale.

Question 1

A resident returns from a medical appointment with a new prescription for an oral antibiotic. The pharmacy delivers the medication, and the delegating nurse adds it to the MAR. The nurse is busy with another resident and asks the Medication Aide to give the first dose. What should the aide do?

▸ Why A is the answer

Reminding the nurse is correct because the Medication Aide scope of practice strictly prohibits administering the first dose of a newly ordered medication due to the risk of unpredictable adverse reactions. Administering the medication is tempting because the aide works under the nurse's delegation, but the aide must refuse delegated tasks that violate their legal scope of practice. Administering and monitoring is wrong because giving the first dose violates scope, and monitoring for allergic reactions requires clinical nursing assessment. Asking another aide to double-check is wrong because a double-check does not change the legal restriction that an aide cannot give a first dose.

Question 2

The unit telephone rings, and a physician is on the line wanting to give a new medication order for a resident. The charge nurse is currently in the restroom. How should the Medication Aide handle the call?

▸ Why B is the answer

Asking the physician to hold or call back is correct because accepting verbal or telephone orders is strictly outside the Medication Aide's scope of practice; only a licensed nurse or pharmacist may do so. Writing down the order is tempting to be helpful, but doing so constitutes accepting a verbal order, which is illegal for a Medication Aide. Taking the order for a routine medication is wrong because the route or classification of the drug does not change the fact that aides cannot accept any orders from prescribers. Repeating the order back is wrong; while this is a safe practice for nurses taking verbal orders, the aide is not legally permitted to take the order at all.

Question 3

According to standard medication administration guidelines, when is the correct time for a Medication Aide to document that a routine medication was given?

▸ Why C is the answer

Documenting immediately after the resident receives the medication is correct because it ensures an accurate, real-time record that the dose was successfully administered. Waiting until the end of the shift is wrong because delayed documentation can lead to memory errors or accidental double-dosing by another staff member. Documenting before entering the room is a common trap; recording a medication before the resident actually takes it is considered falsification of records, as the resident might refuse or drop the pill. Waiting for the nurse to verify is wrong because the Medication Aide is legally responsible for their own documentation and does not need the nurse to verify every routine dose.

Question 1

When preparing a bulk-forming laxative powder for a resident, which technique is correct?

  • A) Pour the dry powder directly into the resident's mouth and follow with a sip of water.
  • B) Mix the powder with a small amount of water to form a paste before administration.
  • C) Stir the powder into a hot beverage and let it sit for ten minutes to dissolve completely.
  • D) Mix the powder in a full glass of liquid and have the resident drink it immediately.✓
Show rationale

Correct. Bulk-forming laxative powders must be mixed in a full glass of liquid (usually 8 ounces) and consumed immediately before the mixture thickens and forms a gel. Incorrect. Pouring dry powder directly into the mouth is a severe choking and aspiration hazard. Incorrect. Mixing the powder into a paste will make it impossible to swallow safely and defeats the purpose of the bulk-forming agent, which requires ample liquid to work. Incorrect. Letting the mixture sit for ten minutes will cause the bulk-forming laxative to gel in the cup, making it too thick to drink.

Question 2

When preparing solid oral medications (pills or capsules) from a multi-dose bottle, what is the correct technique to maintain infection control?

  • A) Pour the pills directly into your gloved hand, then transfer them to the medication cup.
  • B) Use bare, freshly washed hands to quickly place the pills into the medication cup.
  • C) Pour the pills into the bottle cap, then drop the correct number into the medication cup.✓
  • D) Shake the bottle vigorously until the pills fall directly into the medication cup.
Show rationale

This is correct. Pouring pills into the cap and then into the medication cup prevents the caregiver's hands from touching the medication, maintaining strict infection control. Pouring into a gloved hand is tempting, but gloves can still cross-contaminate the remaining pills if you touch multiple surfaces; non-touch technique is the standard. Using bare hands is tempting if they are freshly washed, but touching medications directly with bare hands is a gross violation of infection control. Shaking the bottle directly into the cup is tempting for speed, but it often results in dispensing the wrong number of pills or spilling them.

Question 3

The Medication Aide is preparing morning medications for a busy hallway. To save time, the aide considers popping the pills for the first three residents into separate labeled cups before leaving the medication cart. Why is this practice prohibited?

  • A) Medications must be prepared and administered to one resident at a time to prevent errors.✓
  • B) The cups must be covered with plastic wrap if they are prepared in advance.
  • C) Pills lose their effectiveness if exposed to room air for more than five minutes.
  • D) The Medication Aide must obtain the nurse's permission before pre-pouring medications.
Show rationale

Correct. To ensure the right resident receives the right drug, standard medication safety rules dictate that medications must be prepared and administered for only one resident at a time. Pre-pouring is strictly prohibited. Incorrect. Covering the cups with plastic wrap does not make pre-pouring safe or acceptable; the practice itself violates medication administration standards. Incorrect. While some medications degrade over time, the primary reason pre-pouring is prohibited is the high risk of administering the wrong medication to the wrong resident. Incorrect. The delegating nurse cannot authorize pre-pouring, as it violates fundamental medication safety standards and national guidelines.

Question 4

A Medication Aide is scheduled to give a resident their noon medications, but the resident has left the facility for a family outing and will not return until the evening. What is the appropriate action for the Medication Aide?

  • A) Give the noon medications to the resident's family member to administer during the outing.
  • B) Hold the medications, document the reason they were not given, and notify the nurse.✓
  • C) Leave the medications in the resident's room so they can take them upon returning.
  • D) Document the medications as administered and give them as soon as the resident returns.
Show rationale

Correct. If a resident is out of the facility and unavailable for a scheduled dose, the Medication Aide must hold the dose, document the absence according to facility policy, and inform the nurse. Incorrect. A Medication Aide cannot dispense or delegate medication administration to a family member; if meds are needed for a leave of absence, the nurse or pharmacy must prepare them properly. Incorrect. Medications must never be left unattended in a resident's room due to the risk of loss, ingestion by another resident, or incorrect administration time. Incorrect. Documenting a medication as administered when it was not given is false documentation and a severe medication error.

Question 5

A Medication Aide is preparing to give a resident their scheduled dose of lisinopril. The Medication Administration Record (MAR) lists the dose as 10 mg, but the pharmacy label on the medication bottle states 20 mg. What is the best action for the Medication Aide to take?

  • A) Give half of the 20 mg tablet to match the MAR dose.
  • B) Administer the 20 mg tablet because the pharmacy label is the most current source.
  • C) Hold the medication and immediately notify the delegating nurse of the discrepancy.✓
  • D) Check the resident's chart for the original physician order before giving the 10 mg dose.
Show rationale

Correct. A Medication Aide must never administer a medication if there is a discrepancy between the MAR and the pharmacy label. The aide must stop and ask the delegating nurse to investigate and resolve the issue. Incorrect. The Medication Aide is not permitted to calculate or adjust doses to resolve a discrepancy without the nurse's explicit direction after the nurse verifies the order. Incorrect. The aide cannot assume the pharmacy label is correct; the MAR might reflect a recent order change that the pharmacy has not yet processed, or vice versa. Incorrect. It is outside the scope of practice for a Medication Aide to independently dig through the physician's orders to resolve discrepancies; this is the responsibility of the delegating nurse.
